Improving Change of Direction Ability with Tom Dos’Santos

Freelap Friday Five| ByTom Dos’Santos

Rugby Athlete

Tom Dos’Santos is a Ph.D. student in Sports Biomechanics at the University of Salford, U.K., where he is investigating the biomechanical determinants of performance and injury risk during change of direction. Dos’Santos has published approximately 40 peer-reviewed journal articles and is a certified strength and conditioning specialist (NSCA). He has previously worked as a strength and conditioning coach in soccer, netball, rugby, lacrosse, and BMX. He currently consults on strength and movement profiling with professional rugby and soccer teams in Greater Manchester and is a co-creator of the science of multidirectional speed.

Freelap USA: The penultimate step is of great importance for coaches to understand change of direction. Often, we read the research but need a good explanation of what the role of that step is for redirecting an athlete. Can you share a simple definition for us and explain why it’s important to know how that step works?

Tom Dos’Santos: Changing direction is a multistep action1 and the penultimate foot contact (PFC) plays a major role in facilitating such actions. The PFC is defined as “the 2nd to last foot contact with the ground prior to moving into a new intended direction”16 (figure 1), and it serves two primary functions depending on the change of direction (COD) scenario, angle of COD, approach velocity, and physical capacity for that athlete:

  1. Positional/Preparatory Step – to facilitate an effective whole-body position for effective push-off during the main COD foot contact (i.e., final foot contact (FFC)).
  2. Braking Step – to reduce momentum prior to push-off during the FFC (typically for CODs of sharper angles >60°, but dependent on the COD scenario, approach velocity, angle of COD, and athlete physical capacity).

Foot Contact Figure
Figure 1. The image on the left illustrates final foot contact (FFC), and the image on the right illustrates penultimate foot contact (PFC).


During COD, athletes typically initiate the directional change one or more steps prior to the main COD foot contact. This is known as an anticipatory postural adjustment. These postural adjustments typically include kinematic changes in foot placement, trunk lean and rotation (and pelvis rotation), and head rotation. As shown in figure 2, by typically pre-rotating the step prior to the main push-off (FFC), it helps reorient the whole-body center of mass (COM) toward the intended direction of travel, thus reducing the redirectional demands of the FFC and facilitating faster performance13.

Posture Foot Contact
Figure 2. Illustration of anticipatory postural adjustments during penultimate foot contact (PFC).


For sharper directional changes (i.e., 90° cuts and 180° pivots), the PFC also plays an important role as a preparatory step by positioning the whole-body COM for effective push-off during the FFC. For example, in a 505 agility test, you athletes go through rapid knee, hip, and ankle dorsiflexion to lower the COM. This is performed in a rotated position to reorient the COM toward the intended direction of travel, again reducing the redirectional demands during the FFC. This then puts the athlete in a favorable position for effective push-off during the FFC.

Soccer COD
Figure 3. In sports actions, penultimate foot contact (PFC) acts as a preparatory step in a pre-rotated position for effective COD performance.


When performing COD actions, athletes typically reduce their velocity (i.e., momentum) prior to changing direction. As approach velocity and angle increase, athletes need to reduce their momentum over the PFC, and potentially over a series of steps prior to the FFC, in order to perform the intended angle COD, which we describe as an angle-velocity trade-off18. Based on the literature, it appears that for CODs ≤ 45°, PFC braking forces are limited, and velocity maintenance is key (though the PFC is still important for effective body positioning). However, for CODs >60°, the PFC plays an important role in braking and, undoubtedly, preliminary deceleration is needed. It is worth noting that with greater approach velocities, distances, and angles, preliminary deceleration will occur over a number of foot contacts.

Results from research show that PFC-dominant braking strategies (i.e., maximizing and emphasizing horizontal braking force) could be one way to help improve COD performance14,19,21 while reducing injury risk16,19. From a performance perspective, by braking earlier during the PFC (and potentially steps prior):

  1. We increase braking impulse, which leads to a reduction in horizontal momentum of the COM.
  2. This then allows more effective weight acceptance and preparation for the drive-off phase of the directional change and can allow the FFC to emphasize propulsion rather than braking. This also results in a shorter ground contact time (a key determinant of faster performance).
  3. Greater PFC braking forces are associated with faster 90° and 180° COD performances.14,19,21

From an injury perspective, PFC-dominant braking strategies may help alleviate knee joint loads during the FFC.16,19 Knee joint loads have the potential to strain the ACL and, when high enough, can result in rupture. Emphasizing braking during the PFC is a safer strategy compared to the FFC because:

  1. PFC braking is typically performed in the sagittal plane, where we can utilize the strong hip and knee musculature, and the ground reaction force (GRF) vector is more aligned with the knee joint (though athletes should ensure strong frontal plane alignment).
  2. The knee goes through greater knee flexion range of motion (PFC 100–120° versus FFC 20–60°), which equals greater angular displacement. Thus, based on the work-energy principle, ↑ work = greater reduction in kinetic energy and ↓ velocity.
  3. We reduce FFC GRF and subsequent knee joint loads in FFC—the limb that gets injured during COD actions.
  4. Crucially, ACL injuries occur ≤ 50 ms, which provides insufficient time for postural adjustments (neuromuscular feed-forward mechanism). Thus, reducing momentum is critical for reducing knee joint loads and potential ACL strain.
Reducing momentum is critical for reducing knee joint loads and potential ACL strain, says @TomDosSantos91. Share on X

A review article we have published presents technical guidelines for coaching the PFC.16 Hopefully, coaches understand the importance of the PFC as a preparatory and braking step.

Freelap USA: The isometric mid-thigh pull is growing in popularity here in the U.S., for good reason—it’s safe and valid in determining an athlete’s peak force and rate of force production. Can you share why you feel the test has so much value in sports performance?

Tom Dos’Santos: As the ability to apply force over time intervals (i.e., impulse) underpins movement (i.e., change in velocity), and greater strength (i.e., the ability to exert force) is typically associated with superior dynamic performance (during numerous athletic tasks) and potential injury mitigation, practitioners are interested in methods to evaluate the rapid and maximal force production capabilities of athletes. The isometric mid-thigh pull (IMTP) is a fantastic assessment for evaluating the rapid and maximal force production capabilities of athletes when the testing and data analysis are performed correctly! I strongly encourage coaches to read and follow the recommended testing and data analysis guidelines that we have recently published9.

In comparison to traditional 1RM testing, which requires skill and can be a time-consuming and fatiguing process with the potential risk of injury, IMTP testing is simpler, safer, and a more time-efficient method (typically 5–8 mins to test one subject) that induces less fatigue. Importantly, strong associations have been observed between IMTP peak force (PF) and 1RM back squat, deadlift, and weightlifting performance; thus, the IMTP could be used as a potential surrogate to 1RM testing9.

The critical advantage of IMTP testing is it allows examination of time-limited force expression variables, such as time-specific force, RFD, and impulse over time intervals. Share on X

The critical advantage of IMTP testing, however, is that not only can maximal force production be attained from the vertical ground reaction force data (i.e., peak force) collected from the force plate, but time-limited force expression variables can also be examined, such as time-specific force, rate of force development (RFD), and impulse over time intervals, typically 30–300 ms (figure 4). Being able to examine these rapid production characteristics is significant, and arguably more important than maximal force production, because of the time constraints to express force rapidly during sprinting, jumping, and COD.

Rate of Force Development
Figure 4. IMTP force-time profile created for an athlete. We can use this for strength diagnostics, setting benchmarks, and talent identification.


During IMTP testing, a force-time curve is generated and, subsequently, we can create a “force-time profile” for our athletes (figure 4) that we can use for strength diagnostics and profiling, setting benchmarks, and talent identification. The key variables of interest include PF, time-specific force, RFD, and impulse over specific time intervals (i.e., 30–300 ms), as shown in figure 4. Specifically, PF has demonstrated high within- and between-session reliability measures across a range of different athletic populations7, and time-specific force values appear to provide the best reliability measures compared to RFD and impulse9,15. RFD, impulse, and time-specific force variables provide similar information; thus, I recommend practitioners inspect time-specific force values along with PF, due to the better reliability measures.

The aim of strength and conditioning is to shift the force-time curve up (i.e., magnitude of force) and to the left (rate of force development), and the IMTP directly allows practitioners to identify strengths and deficiencies so that we can create individualized training programs. We can monitor the effectiveness of training interventions by reassessing IMTP force production (under standardized conditions) and determining whether the changes are greater than the smallest worthwhile change (SWC) or smallest detectable difference (SDD) (figure 5). We can continually go through this process throughout our mesocycles and macrocycles.

Finally, we can also use the IMTP to assess neuromuscular preparedness and training readiness.24 As illustrated in figure 6, practitioners may consider using the IMTP as a neuromuscular preparedness/training readiness tool prior to sessions to identify athletes who may be displaying reductions in maximal or rapid force production characteristics. This reduction could potentially be viewed as “fatigue,” and, thus, practitioners can delve deeper by identifying the cause and devising strategies to overcome the “fatigue.”

It is stressed that if practitioners are going to use the IMTP as a neuromuscular preparedness assessment, they should follow three recommendations:

  1. Establish their own between-session reliability measures.
  2. Select a variable that will be sensitive to change.
  3. Establish individual SWCs/SDDs to determine “real” changes in performance.

Norris et al.24 recently found that PF was not meaningfully suppressed post Australian rules football (ARF) matches (up to four days) and that RFD 0–50 milliseconds and 100–200 milliseconds were variables more sensitive to changes (i.e., reductions) post ARF matches (2–4 days).

Freelap USA: The change of direction deficit is a practical and simple test for coaches. Knowing that most strength coaches still struggle to get access to technology, how can they use simple timing gates and software to get more out of 5-10-5 tests?

Tom Dos’Santos: As we are all aware, an assessment of COD performance based on completion times that only use timing gates is heavily biased toward faster athletes22, and the COD deficit has been developed to provide a more isolated measure of COD ability that is not biased toward faster athletes17,23. This can be simply calculated by subtracting the COD completion time by a linear speed time of the equivalent COD test distance. The commonly used method for calculating COD deficit is: 505 completion time – 10-meter sprint time. These tests commonly feature in testing batteries for most practitioners and sports, and subsequently require very little effort to calculate (as you have already collected the data).

As it is advantageous to be equally proficient at changing direction rapidly from both limbs, I encourage practitioners in their COD assessments to first examine COD performance from both limbs to establish if any athlete displays a performance deficit when turning/COD from either limb. Doing this can help inform future training for that athlete.

Next, practitioners with access to contact mats, OptoJump, or other software that can be synced with timing gates could gather a lot of information during the 505, 5-10-5, or other COD speed assessments. Rich Clarke has recently been at the forefront of devising simple strategies to gain more insight into COD and deceleration ability during tasks such as the traditional or modified 505 (figure 7), and I recommend that coaches read his posters and presentations on his ResearchGate profile.

COD 180 degrees
Figure 7. How to gain more insight into COD ability during 180° assessments (adapted from Rich Clarke). Clarke suggests obtaining more information on the entry profile prior to the COD (red arrow), COD ground contact time (black cross), and exit profile (green arrow), by syncing timing gates with a contact mat, OptoJump, etc.


If we look at figure 7, Rich Clarke suggests that we could obtain more information regarding the entry profile prior to the COD (red arrow), COD ground contact time (black cross), and exit profile (green arrow), by syncing timing gates with a contact mat, OptoJump, etc.

In the hypothetical example above, an athlete performs a modified 505 in 2.5 seconds. We can divide this total time into three components to gain better insight into how they achieve the time:

  1. Entry time (red arrow). Duration from athlete crossing start timing gate (first break of beam) to touchdown of the COD at the turning line = 1.1 seconds (1st split time).
  2. COD (black cross). Duration from touchdown of COD to toe-off of the COD (performed at the turn line) = 0.4 seconds (2nd split time).
  3. Exit time (green arrow). Duration from end of COD GCT to athlete crossing the finish timing gate = 1.0 second (3rd split time).

By applying this method, the practitioner can gather more information on how the total time was achieved and determine where an athlete’s strengths and deficiencies are in terms of deceleration, COD GCT, and reacceleration. They can then use this to inform future training. It is worth noting that I have adapted Rich Clarke’s method, as he adds 50% of COD GCT to the entry and exit times and does not include COD GCT in terms of his profiling.

Personally, I think it would be beneficial to divide the total time into the three components, but it is the discretion of the practitioner as to which method they apply, as long as analysis procedures are standardized longitudinally when monitoring changes. Irrespective of method, the process outlined in figure 7 could be applied to the traditional 505 (as Rich Clarke has done), the 5-10-5, or cutting tasks.

Finally, for coaches who do not have access to timing gates, Carlos Balsalobre-Fernandez has developed and validated the COD timer app, which uses the high-speed video capabilities of a smartphone to film COD tests2. Carlos has initially validated the app for modified 505 COD speed tests. This simply requires the coach to stand perpendicular to the start/finish line, film the trial using a smartphone, and manually select the start, touchdown, and toe-off of the FFC, and finish. Consequently, the coach obtains total time and GCT for the COD.

I believe Carlos is working on updating the app to encompass the entry and exit times that Rich and I have discussed, which would be a great addition. A video outlining how to use the COD timer app is presented below.

Freelap USA: The dynamic strength index is a crude ratio but some coaches like it because it’s simple to calculate. Can you go into the pros and cons of this metric?

Tom Dos’Santos: The dynamic strength index (DSI), also known as the dynamic strength deficit (DSD), is a combined assessment method that examines the ratio between dynamic (ballistic) propulsive PF (i.e., squat or countermovement jump) and isometric PF (i.e., IMTP or isometric squat) for the lower limb, and the ratio between dynamic bench press throw PF and isometric bench press PF for the upper limb25,26. For the purpose of this section, I will focus on lower-limb DSI, but we are essentially assessing how much of an athlete’s strength potential can be expressed dynamically.

The key aspect of the ratio is that it is used to assist in the profiling and training prescription for an athlete. As shown in table 1, Shepperd et al.25 suggests an athlete displaying a ratio <0.60 would warrant training emphasis on ballistic force expression, >0.80 would warrant training emphasis on maximal force expression, and 0.60–0.80 would warrant a combination of ballistic and max force expression training.

Dynamic Strength Index
Table 1. DSI training recommendations. Coaches’ testing batteries commonly include jump and isometric strength assessments, so this ratio would require very little effort to calculate.


As coaches’ testing batteries commonly include jump and isometric strength assessments, this ratio would require very little effort to calculate. We have shown that better between-session reliability measures are obtained when using CMJ PF versus SJ PF10, most likely attributed to the CMJ being easier to standardize and perform. However, it is imperative that coaches ensure they are using PF during the propulsion phases of the CMJ, not the braking phase. This is extremely important for athletes who may display bimodal CMJ force-time profiles, as illustrated in figure 8.

Furthermore, athletes can also alter their CMJ strategies to alter their force-time characteristics, which coaches should be aware of. Verbal cues can affect force-time characteristics; thus, it is imperative that CMJ instructions are consistent longitudinally. Typically, “jump as fast and as high as possible,” is common practice and produces reliable measures.

Peak Jump Forces

Additionally, I prefer IMTP testing to isometric squat testing. In my experience, athletes dislike driving up against a fixed immovable bar during isometric squatting due to the spinal compression. Irrespective of testing method, coaches should be conscious of the method of obtaining DSI when comparing values to normative data across the literature.

A significant limitation of the dynamic strength index (DSI) is that it is only a ratio, and interpretation of the ratio alone could lead to incorrect evaluations, says @TomDosSantos91. Share on X

A significant limitation of the DSI is that it is only a ratio, and interpretation of the ratio alone could lead to incorrect evaluations. For example, an athlete may display a ratio of 0.6 (CMJ PF = 18 N/kg / IMTP PF = 30 N/kg), and based on the ratio alone, they would warrant combination training. However, inspection of the IMTP PF indicates that the athlete is relatively weak (based on relative IMTP data from our lab–table 2) and would most likely benefit from getting stronger (i.e., developing maximal force expression)11,27. Thus, I advise caution when looking solely at ratios, and I strongly encourage coaches to look at the absolute values of the two components (i.e., CMJ PF and IMTP PF) for a more holistic overview.

IMTP Relative Peak Force
Table 2. IMTP relative PF benchmarks, which help practitioners decide whether an athlete needs a training emphasis on maximal or rapid force expression.


Alternatively, I suggest practitioners examine relative IMTP PF to decide if an athlete warrants emphasis on maximal or rapid force expression. Table 2 provides some benchmarks from our lab (i.e., inclusive of BW). If an athlete achieves very good to excellent scores for IMTP relative PF, they would benefit from shifting their training emphasis to rapid force production. If they do not hit these benchmarks, I suggest targeting maximal force expression.

Additionally, I encourage coaches to examine additional variables, not just DSI, when profiling their athletes. Variables such as RSI during a 10/5 or DJ and inspecting alternative variables for CMJ testing such as jump height, time to takeoff, and subsequently RSI mod can be used for profiling and to assist in the training prescription for an athlete.

Freelap USA: Asymmetries are complicated to manage, as there are natural differences between right and left. What can youth or academy coaches do to help screen out problems but not overreact to differences in leg power? What do you think is a good approach to get a practical assessment in place for high school athletes ages 14–18?

Tom Dos’Santos: An inter-limb asymmetry is simply a difference in performance or function of one limb with respect to the other4, and it can be categorized into strength (force asymmetries—i.e., IMTP PF) and skill asymmetries (i.e., difference in COD time between left and right limb)20. Before I discuss the methods and processes for assessing asymmetries, we first must look at the bigger picture and question whether being asymmetrical is a problematic issue. Currently, there is no clear consensus that an athlete with greater strength asymmetries (i.e., PF, impulse/ power deficits between limbs) will display inferior athletic performance and is predisposed to increased risk of injury.

There is currently no clear consensus that an athlete with greater strength asymmetries will display inferior athletic performance and is predisposed to increased injury risk. Share on X

The issue with strength asymmetries is that they are task- and metric-dependent, with the magnitudes of % imbalance inconsistent across tasks (e.g., isokinetics typically have a greater % imbalance than IMTP PF), and metrics within the same task (e.g., IMTP PF % imbalance < impulse % imbalance)3,28. Additionally, the directions of asymmetry are also task- and metric-dependent3,28. For example, an athlete may display superior IMTP PF on their right limb but display greater concentric knee extensor strength during isokinetic assessments for the left limb. This issue has been excellently highlighted by Chris Bishop and Chris Thomas in recent work investigating strength asymmetries in team sport athletes, and it shows the difficulty in diagnosing a consistently dominant and stronger limb.

Personally, I would be more concerned about an athlete’s coordination and skill asymmetries in performance during dynamic tasks; for example, examining inter-limb asymmetries in jump-landing mechanics, COD performance, etc. I would argue that athletes displaying suboptimal landing mechanics for their left limb are of greater concern than a 15% imbalance in IMTP PF, which is only reflective of that one muscle quality during that specific task. Nevertheless, when exploring strength asymmetries, there is a whole range of tests available, as outlined excellently by Chris Bishop6 in table 3 below.

Testing Battery
Table 3. A look at the testing battery for assessing asymmetries. (Taken from Bishop et al. (6))


While looking at strength asymmetries can be insightful, there are a whole range of factors that we must consider. Once the coach has chosen their tests (and acknowledged the task-dependent nature of asymmetries), we must decide how to calculate and determine a meaningful imbalance between limbs. Chris Bishop and Chris Thomas have done some great work in this area, and there are a whole range of equations that you can use to calculate a % imbalance or ratio.

Importantly, the different equations result in different % imbalances (which may alter your evaluation)4. Bishop et al.5 has recommended the use of this equation—assessments % imbalance = (D-ND)/D×100—for unilateral, with D and ND referring to stronger and weaker limbs, respectively. Additionally, for bilateral assessments, this equation has been proposed: % imbalance = (D-ND)/total of left and right limb×100.

Next, the difficulty is how to define a meaningful imbalance between limbs. Currently, there is no consensus across the literature for an asymmetry threshold, with various methods employed. A 10–15% imbalance has generally been considered a meaningful asymmetry; however, there is very little evidence to support this. Coaches may consider comparisons to normative data or adding the mean % imbalance and SWC for their group of athletes to define an asymmetry threshold.

It has been recently suggested that in order to establish a “real” asymmetry between limbs, the difference must exceed the variability/error (% imbalance = 10%, % CV = 5%). However, in order to be confident that a real asymmetry is present, I would suggest establishing the between-session reliability to see if the % imbalance and direction of asymmetry are consistent. For example, does an athlete displaying 15% greater IMTP PF on the right limb also display the same imbalance for the right leg 48/72 hours later? If an athlete does not consistently display a similar % imbalance for the same leg, I would caution against defining an athlete as asymmetrical and ask coaches not to overreact in this situation.

If an athlete doesn’t consistently display a similar % imbalance for the same leg, I would caution against defining an athlete as asymmetrical, says @TomDosSantos91. Share on X

As stated earlier, the issue with strength asymmetries is that they are task-dependent and can vary between tasks (i.e., athlete right limb dominance for IMTP PF but left limb dominant for CMJ propulsive impulse). Additionally, the metrics during the same task, such as an IMTP, can also fluctuate in terms of limb dominance. Furthermore, Bishop et al. has also highlighted that the magnitudes and directions of asymmetry are not necessarily consistent between sessions3, longitudinally over a season, and they are also sensitive to post-match fatigue (24/48 hours)8. These issues are problematic and can lead to different evaluations being made in terms of an athlete’s asymmetry profile and potentially erroneous conclusions that could lead to incorrect training prescription.

Finally, the major issue to consider is that asymmetries are simply a percent or ratio, and, as I stated regarding DSI, we must also take into account the absolute values and compare these values to some normative data/benchmarks. For example, an athlete may be strong and asymmetrical, but their weaker limb still outperforms the rest of the squad. Alternatively, you may have an athlete who is symmetrical but weak and the worst performer for that metric in the squad.

When monitoring changes in asymmetries, I not only advise coaches to inspect the % imbalance, but they must consider the direction of asymmetry (i.e., an athlete may still have a 10% imbalance, but the dominance has changed from left to right). More importantly, they must also inspect the absolute values because an athlete can reduce their % imbalance by the dominant limb becoming weaker while maintaining strength in the non-dominant limb.

Ideally, we’d want athletes to be symmetrical in terms of force production and skill. However, there’s evidence that simply getting athletes stronger can reduce strength asymmetries. Share on X

In an ideal situation, we would want athletes to be symmetrical in terms of force production and skill. However, there is evidence that simply getting athletes stronger can reduce strength asymmetries12. Generally, I would concentrate my efforts on getting athletes stronger and to a high strength level (i.e., 1.5–2×BW squat/ IMTP PF 45 N/kg) before overreacting and specifically targeting force asymmetries. Conversely, I would argue skill asymmetries are a problematic issue, and every effort should be made to correct such imbalances in landing mechanics, COD ability, etc. between limbs.

Plyometric Bounding

A Unilateral to Bilateral Training Progression for Team Sports

Blog| ByCameron Josse

Plyometric Bounding

Training team sport athletes is complex, with so many ways to prepare them and variables to consider. In truth, any program that allows for the progressive overload of various forms of intensity (not just weight lifted, but also increases in outputs of power, speed, etc.), performed with safe biomechanical positioning, will typically lead to positive results from a physical preparation context.

We see this time and time again with most high-level team sport athletes having similar levels of physical fitness despite each strength and conditioning staff having their own unique approach to the problem. However, team sports exist as multiple layers of complexity and chaos, and to have a better understanding of preparation protocols, it’s necessary to try and consider all the layers as best as possible.

‘Chaoplexity’

“The term chaoplexity brings together the theory of complexity and chaos theory…the complexity of the game exists in a world founded on chaos. Combine this with social laws, the rules of competition, and training or practice schedules, and we see that players are experiencing what can only be described as chaoplexity.” – Fergus Connolly

For me, part of this chaoplexity is understanding how all the various layers interact and how that will determine what I choose to do with my athletes from a physical preparation standpoint. This is especially important for younger developmental players who stand to gain a lot from physical preparation in their overall performance.

I want to expose my athletes to various motor skills and coordination challenges, bring up their power and capacity outputs, and do all of this while still considering the impact of skill acquisition, sports practice, and sports competition. I am in search of structured training variation, based on:

  • Desired training effects
  • Time of the year
  • The specific athlete
  • Multiple other factors

“Variation is the key to efficient coaching. This does not only apply to optimizing motor learning processes. When planning physiological adaptations during training, variation should again be the main feature of the training…Variation is therefore the first and most important training principle, along with individualization.” – Frans Bosch

This article presents one ideological approach I use in my current search for structured variation. This approach is specifically geared toward team sport athletes. Based on the demands of team sport physical preparation, I use a system that progresses the general (italicized on purpose) strength and power training by building a foundation of unilateral activities first, and then shifting toward a realization of high-power output with bilateral activities. This general training progression is layered with specialized forms of speed, power, agility, and endurance training performed in conjunction with what’s laid out here.

Varying Unilateral and Bilateral Strength and Power Training

First off, this is not a new concept. I know for a fact this idea has been used before (see the picture of Joe DeFranco’s notes from a Charles Poliquin seminar below). But for me, this whole idea started from a simple conversation with my good friend Chad Dennis, a highly experienced strength coach for the past 17 years.

Poliquin Notes
Image 1. Joe DeFranco’s notes from a Charles Poliquin seminar in 1999. Here, Poliquin discussed improving vertical jump performance by starting with a base of stability first and then progressing to emphasizing max strength and power in later phases.


Chad visited me at DeFranco’s Gym in New Jersey earlier this year, and I reviewed my training program principles with him. I was trying to add some variability into my program by alternating between unilateral and bilateral emphases for strength and power every couple of weeks. At the time, I was operating based on a couple of things I had learned. Number one, thanks to some reading on recent theories of motor learning, I learned the importance of variability for resilient, adaptable skill development. Number two, thanks to plenty of conversations with my friend Mike Boyle, I learned that unilateral training is typically an untapped area of potential for great training effects. I knew I wanted to try to include both concepts in my program, so this was the solution I developed.

I wanted to include both variability, which is important for resilient, adaptable skill development, and unilateral training, a typically untapped area of potential for great training effect. Share on X

Chad reviewed my notes and then took a couple of breaths before asking me, “Have you ever tried doing a foundational period of unilateral emphasis followed by a specialized period of bilateral emphasis?” I asked him to elaborate on his thoughts, and he said, “Well, for me, I tend to look at unilateral power as falling more in line with ‘strength,’ whereas bilateral power seems to align better with ‘speed.’ There’s something there with the kinetics and the ground contact times.”

Movement Physics Tell the Story, Not Movement Appearance

As soon as Chad said that, my mind wandered to two specific places. The first was Triphasic Training by Cal Dietz and Ben Peterson, where they wrote the following:

“A single leg plyometric, as shown by [a] motion analysis machine, is so much slower in producing forces…With double leg plyometrics…there is higher potential for developing speed because of the shorter amortization phase, and thus, a more explosive rebound…Single leg plyometrics should be viewed more as a strength plyometric whereas double leg plyometrics develop speed.” 4

We often assume that single leg training is more “sports-specific,” since most athletic actions occur on a single limb. When speaking strictly kinematically—that is, based on how a movement appears—then yes, that’s true. But when we consider the kinetics of the motions—that is, how the movement was caused in terms of the forces and time frames involved—we start to see that we can’t just look at the appearance of a movement. In order to better determine the desired training effect, we must also consider the physics involved.

The other place where this thought hit home for me was a recollection of work by Derek Hansen highlighting ground contact time as a simple way to gain insight as to where training effects occur along the force-time continuum.

GCT in Athletic Actions
Figure 1. A representation of various contact times based on typical athletic actions for team sport athletes and how these contact times seem to align with different physical qualities.


From this image, we can easily see how all these activities involve a single limb contacting the ground, but the force-time components of each action and ground contact are very different. Sprinting at top speed will ultimately require a single leg action that is at least four times faster than that of coming to balance in a full deceleration.

It’s not enough to think in terms of “single leg is more specific” when designing programs—it’s the overarching desired training effect that is most important. Share on X

So, it’s not enough to think in terms of “single leg is more specific” when designing programs—it’s the overarching desired training effect that is most important. As I discovered, taking a broader perspective on the why’s of training brings up some interesting thoughts and questions into when, how, and why to use different forms of unilateral and bilateral training.

Unilateral vs. Bilateral Power

Unilateral power and plyometric training are growing in popularity, especially with team sport athletes for whom having the ability to display power on one limb in multiple directions is an obvious advantage due to the demands of the game. Training in multiple planes seems to be an important factor, with research supporting the notion that having single leg power, deceleration, and coordination in multiple planes is an area of necessity when designing training programs for team sport athletes.1, 9, 10, 12

Both bilateral and unilateral power training will result in general adaptations associated with improvements in power, namely speed of muscle contraction, faster motor unit activation, enhanced neural firing rates, decreased duration of the stretch-shortening cycle, and improved proprioception. However, there are specific adaptations that occur depending on the training means used.

The reported training effects following unilateral power and plyometric training may occur over a period of 6–12 weeks. These effects seem to follow the SAID principle, where specific adaptations occur based on imposed demands. So, it’s typically reported that training with unilateral activities will have the greatest impact on unilateral actions, though some research has suggested that bilateral countermovement jump performance may also improve following a period of unilateral jump training1.

Figure 2 presents some of the reported effects of unilateral power and plyometric training:

Rationale Unilateral Power
Figure 2. Training adaptions that coaches can target with multi-planar, unilateral power methods.


In addition, all locomotive motion will require the transmission of force into the ground with various time constraints (dependent on the task). Therefore, we can use ground contact times as a simple indicator of how unilateral and bilateral power activities might differ in their force-time expression and how they align with different athletic actions like accelerating, sprinting at top speed, changing direction, or decelerating.

GCT Various Actions
Figure 3. Common power exercises shown in relation to ground contact times.

Preparing for Collision

Another point of consideration with unilateral power training for team sport players relates to tissue resiliency and robustness. For contact sports like rugby and American football, collision is a major concern. Thanks to advances in integrated accelerometry (IA) technology, researchers can monitor the magnitude and frequency of impact and collision in team sport players.

It has been reported that the prevalence of high-velocity eccentric actions (i.e., changing direction and deceleration), in combination with tackling and other forms of impact trauma, induces a significant load to the players’ musculoskeletal systems, as evidenced by large elevations of creatine kinase (CK) and cortisol following match play. Soft tissue trauma is part of the game, and if players are loaded too much or too little in training, it stands to reason that noncontact soft tissue injuries are likely imminent.11

However, it seems that the bulk of collision loading in contact sports like rugby and American football occurs in the form of ground-reaction forces generated by accelerating, changing direction, jumping, or rapid decelerations, all resulting in inertial load on the body.5, 15

Force plate data has helped shed light on the magnitude of these impacts as measures of vertical ground reaction forces, which can range from 2–7 times the body weight of a team sport player during jumping, change of direction, and sprinting actions. Further, these are actions that are usually sustained on one leg due to the dynamics of team sport game play.

Vertical Ground Force
Figure 4. Table representing measures of vertical ground reaction forces associated with athletic and training activities (3).


It’s worth mentioning that explosive/elastic activities incorporate a greater influence of the entire musculotendinous unit to help aid in force production. The greater contribution from elastic structures like tendons allows for the body to sustain such high forces. We simply cannot simulate these forces in a weight room, due to the slow nature of resistance training, which directly stresses the muscle more. Thus, it’s important that we incorporate power and plyometric activities to develop the tissue integrity, proprioception, and coordination required to perform rapid, explosive actions competently and safely.

“The moment you enter a gym, forget about specific training unless you are a bodybuilder, a powerlifter, or a weightlifter.” – Henk Kraaijenhof

One paper investigated the demands of American football using a workload-injury etiology model and determined the following3:

  • Coaches and practitioners working with American football players need to expose them to a high number of collisions in training to better prepare players for game demands.
  • A balance must exist between the number of exposures required to improve fitness and the number that elicits negative fatigue responses and increased injury risk.
  • Players who can produce high average inertial load values were less susceptible to contact and noncontact soft tissue strains and sprains.
  • Players with a high level of neuromuscular responsiveness and control can produce high inertial load values through rapid acceleration, deceleration, and change of direction, which may offer protective benefits.

Vertical Stiffness
Figure 5. A comparison of good and poor vertical stiffness in sprinting, based on the work of Dr. Ken Clark.


So, being able to overcome the resistance of inertia with great efficiency seems to have a protective effect for team sport athletes. This information falls in line with how unilateral power training in multiple directions is a necessary training consideration for a complete team sport program. The forces of unilateral plyometric activity appear to be just as high as those of a bilateral countermovement jump, revealing a unique training stimulus that can help prepare the structures of the lower limbs for high impact loading at fast speeds.

The forces of unilateral plyometric activity appear to be just as high as those of a bilateral countermovement jump. Share on X

The research seems to indicate that the most complete training program is one that incorporates a combination of bilateral and unilateral power training. This makes sense when looking at the ground contact image in figure 3, where bilateral and unilateral power and plyometric activities are scattered all along the force-time continuum. 

Unilateral vs. Bilateral Strength

Speaking of implementing a complete program, we can’t neglect the development of muscular strength. It seems there are benefits to using both unilateral and bilateral means in this realm as well. The benefits of general strength training are well-established and beyond the scope of this article, but the primary adaptations associated with heavy resistance training include enhanced neural capabilities, increased energy stores, muscle gain and improvements in body composition, anabolic hormonal responses, and potential enhancement of ligament, tendon, and collagen integrity.8

Most resistance training research has investigated effects using bilateral strength exercises like the leg press, barbell squat, or barbell deadlift. The research regarding training for maximal strength using unilateral exercises pales in comparison to the research on bilateral barbell training. In practice, most coaches perform unilateral strength training, using exercises like rear foot elevated split squats, pistol squat variations, or single leg deadlift variations. The following is a quote taken from the classic training text Supertraining by Yuri Verkhoshansky and Mel Siff:

“Research has shown that the transfer of strength developed in bilateral training (e.g. using squats or power cleans) offers specific improvement in performance in bilateral events…while unilateral training (e.g. with dumbbells or split cleans) enhances performances more effectively in unilateral activity such as running, jumping.”

In recent peer-reviewed literature, the reported performance gains associated with unilateral strength training show similar effects to what is reported with bilateral strength training, which may be important for athletes who are contraindicated for exercises like barbell squats or deadlifts. If axial loading is an issue, especially for older athletes in contact sports who have experienced low back or hip injuries and feel discomfort when loading bilaterally, unilateral exercises may prove to be an effective form of strength training for the lower body.

In recent peer-reviewed literature, the reported performance gains associated with unilateral strength training show similar effects to what is reported with bilateral strength training. Share on X

Thus, more work is needed before we really understand what adaptations occur from heavy unilateral strength training.

Rationale Unilateral Strength
Figure 6. Summing up some key literature claims from both peer-reviewed journals and empirical theories with regard to training unilateral strength.


In my own experience using unilateral exercises with my athletes and conversing with them about the movements, most of them tell me that they feel an element of athleticism with the unilateral strength exercises. I imagine that this is due in part to unilateral exercises emphasizing cross-body patterns and putting the joints in positions with more degrees of freedom, requiring more stability.

Here are some of the reasons that I personally like using unilateral strength exercises, especially early in a developmental training progression:

  • Unilateral strength exercises are naturally more unstable, emphasizing stability, coordination, and balance in the face of more degrees of freedom.
  • Due to greater instability, athletes should perform unilateral strength exercises with a controlled tempo, emphasizing time under tension for greater local muscular endurance and hypertrophy.
  • Unilateral strength exercises will reduce the overall axial load, allowing for a period of unloading the spine while emphasizing strength and tension of the local leg musculature early in the training process.
  • With split patterns and positions, mobility may be trained against load in positions like deep hip/knee flexion, hip extension, and ankle dorsiflexion while minimizing spinal compression.

Field First, Weight Room Second

In my programming, I always take a skill-centric view and work backward from the athletic qualities needed in the sports game. This means that I always think in terms of field first, weight room second.

Certain athletic activities will demonstrate massive vertical ground reaction forces in minuscule amounts of time—let’s just consider how top-speed sprinting can produce up to 6x body weight of vertical ground reaction force in about a tenth of a second on one leg! You just can’t match this kind of output in the weight room. I can find activities that may have a positive correlation and potential transfer to sprinting performance in the weight room, but if I really expect to build better sprinting with my athletes, I must have them sprint.

I always take a skill-centric view and work backward from the athletic qualities needed in the sports game. This means that I always think in terms of field first, weight room second. Share on X

The same goes for other athletic activities like jumping, change of direction, and deceleration. I must train these qualities as they exist on the field in order to keep the experience specific to what’s encountered in the game. So, for agility work, I will use game-like situations to put my athletes in positions that feature specific perceptual-cognitive elements to help hone their skills of anticipating, reading, and reacting appropriately to what they see.

A popular sprint training progression from Charlie Francis is the Short-to-Long Model, where we expose athletes to shorter distances (i.e., 10–20 yards) earlier in the training process and gradually progress to longer distances over time. This makes sense because shorter distances do not feature speeds or ground reaction forces that are nearly as intense as longer distances, where athletes reach top speeds. Therefore, athletes can train at high intensities of sprinting with less risk of structural damage early on by using shorter distances and gradually expanding their power and speed exposure with longer distances as the program carries on.

In similar fashion, when I train for change of direction speed or agility in the form of open/reactive game experiences, I use a progression of “small to large,” where I start with smaller field spaces early on and gradually increase to larger field spaces. By starting with small spaces, my athletes experience these high-intensity movements with less impact, since the spaces and movement speeds are reduced. As the program progresses, I use larger spaces, and changes of direction feature larger impacts from decelerating from higher movement speeds.

High Intensity Training Components
Figure 7. This table portrays different forms of training exercises and how they might align with and transfer to different sprint distance segments based on their execution and intent.

Common Denominators of Effective Programming

When I look at various texts on programming and periodization for sports, the principles seem to be consistent, regardless of the specific periodization model applied, whether it is the traditional model, vertical integration system, block periodization model, block training system, or whatever. There will always be a General Preparatory Period that initiates the training process, followed by a Specific Preparatory Period to emphasize more specific qualities, and finally a Competitive Period where the effects of training are realized in live competition. There is also a Transition Period of reduced loading following phases of competition or team sport seasons.

Comparing Periodization Models
Figure 8. This table breaks down principles from multiple periodization models (6–8,14).


The Vertical Integration Model, also sometimes referred to as the Complex-Parallel Model (popularized by the late sprint coach Charlie Francis), seems to be the most advantageous approach for intermediate to advanced team sport athletes.

This model is characteristic of keeping all forms of training present throughout the entire year—hence, vertically integrating the training components like the traditional model—but rotating the emphasis of training into blocks or phases and accounting for greater inclusion of technical/tactical training. It is a system that falls somewhere in between the traditional model and the block models, where definitive blocks are used but all physical qualities are present to some degree all year long due to the nature of team sport requirements.

Team sports are incredibly complex in comparison to individual sports, with a wide array of physical qualities always needed, far more tactical strategy involved, and a greater repertoire of technical skills to develop. In addition, team sport athletes will not need the same level of physical output as an individual sport athlete. A sprinter lives by maximizing speed and a thrower lives by maximizing power, but a team sport player only requires enough physical output to operate effectively within the rules of the sport game.

Progressing from Unilateral to Bilateral Emphasis

The idea of progressing from a unilateral to bilateral emphasis for strength and power is about starting with a base of coordination and gradually shifting toward increasing motor outputs in the general training as the specific training on the field becomes more intense and more technical in relation to the sport. Thus, in team sports, this shift toward specificity will necessitate increasing the intensity and exposure to field-based activities with faster speeds, higher power, more intense change of direction, and greater perceptual-cognitive complexity using open/reactive games and agility training.

It’s also important to spread out the stresses of each training period so that the most important qualities can flourish. With unilateral training, there is an expectation of greater soreness in the local tissues and musculature. This can prove problematic when we want to really emphasize technical elements and intensified field training during the SPP. Sore legs make speed and technique work difficult.

It makes more sense to emphasize unilateral training when there is reduced field training intensity, typically earlier in the training process. Share on X

In the early training periods, specialized technical training is less of a priority, so it allows for the opportunity to stress the structures of the lower limbs with less worry of reduced quality in high-speed efforts or activities of high technical demand. It’s much easier to have a quality 10-yard sprint with some leg soreness than it is to have a quality 40-yard sprint. Therefore, it makes more sense to emphasize unilateral training when there is reduced field training intensity, typically earlier in the training process.

Unilateral to Bilateral Jumps
Figure 9. Progressing from a unilateral jumps emphasis early in the off-season to a bilateral emphasis later in an off-season training program.


In the SPP periods, the primary unilateral emphasis shifts in favor of what’s being done on the field with more specialized training. Here, the field work must be of high quality to get the desired training effect. So, we can reduce local soreness by shifting the emphasis of the general power and strength work in favor of bilateral activities, which also gives us a nice one-two punch because the kinetic qualities of bilateral training align very nicely with higher speeds on the field.

Unilateral to Bilateral Strength
Figure 10. Progressing from a unilateral strength emphasis early to a bilateral emphasis later in the off-season training program.


With bilateral training, more power and speed are possible since the force effort is spread across more total body structures. Monitoring the velocity of barbell lifts shows that this is apparent, as a repetition of a barbell squat at 80% 1RM will move faster and with more power (due to greater load) than a repetition of a barbell rear foot elevated split squat at 80% 1RM.

Sample Progression
Figure 11. A sample of how I progress from an emphasis on unilateral to bilateral training over the course of a full off-season period.


IMPORTANT NOTE:

Just because the emphasis of a certain training phase may be on unilateral training, this does not mean that we abandon bilateral activities. On the contrary, keeping elements of bilateral training present while emphasizing unilateral training will prove fruitful, allowing for athletes to develop the motor control needed for bilateral activities that we will load later.

Just because the emphasis of a certain training phase may be on unilateral training does not mean that we abandon bilateral activities. Share on X

For example, I keep bilateral squat and hinge movements present in accessory weight training, using lighter loads and manipulating execution tempos to emphasize eccentric or isometric control. I also perform jump testing with my athletes all year long, so exposure to bilateral squat jumps, countermovement jumps, depth jumps, and the reactive strength index (RSI) is consistent in all phases.

What About the In-Season?

The main body of this article deals with the off-season preparation periods. However, given that the specific context is in relation to team sports, we come across an issue: Team sports like basketball, soccer, and volleyball require competition almost all year long. For these sports, there is a greater requirement to develop a knowledge of the stress imparted on players from sports practice and games and to make educated decisions on how to structure the in-season training.

In his new book, Methodology of Training in the 22nd Century, Coach Henk Kraaijenhof explains how we simply have to throw many periodization models out the window with in-season training, as the majority of the models were designed at times when athletes were simply not competing as frequently as they do in today’s commercially driven world. Thus, we must take a more agile approach, like the morphocycle design of tactical periodization pioneered by Vitor Frade and brought further to light in Fergus Connolly’s Game Changer and my most recent book with Fergus, The Process: The Methodology, Philosophy & Principles of Coaching Winning Teams.

This kind of approach is based on the following components:

  1. Preparedness – The underlying long-term adaptations that have occurred for the player, such as overall strength, power, speed, endurance, and other qualities based on previous experiences and training exposure. This requires knowledge of the player’s sport involvement and training history and how it affects what must be done during in-season practice and training interventions.
  2. Readiness – How well the player’s body is functioning at the current moment. Readiness must be high upon entering game day and must be maximized as much as possible for important conference games or championship games. Improper training and practice interventions will disrupt player readiness and game day performance.
  3. Psychological Resilience – The player’s ability to cope with mental stressors associated with high levels of competition. Practice and training sessions have an impact on a player’s psychology, as physiology is largely intertwined with a player’s mental state and one will impact the other.

During a competitive season, a coach must keep these three components front of mind. Most team sports play at least one game each week, and some upward of three or more depending on the time of year. The game itself is the most important testing protocol for sports performance, meaning that sports practice becomes the most important training session.

In terms of physical preparation, it becomes about winning small battles. So, there is no answer as to how to progress the training; there is only a necessity to be aware of potential training effects and the insurance that what is imposed on the players aligns properly with what is happening in practice on the road to game day.

Vertical Pulling

Programming for a More Powerful Vertical Pull

Blog| ByJeff Richter

Vertical Pulling

In my previous post, I presented a case for why the pursuit of power development in vertical pulling is a worthy endeavor. Through my own experience and the limited research available, I also tried to project how to use VBT to assist the process of creating more intentional and tangible adaptations in this regard.

Encountering athletes with varying strength and power in vertical pulling is the obvious norm, so there are particular considerations for how we program for athletes at different stages of development. Also, individual athletes come to training on a given day in various states depending on their nutrition, hydration, sleep, DOMS, and general state of recovery. Even psycho-social factors such as relational and financial stressors can affect a training session.

I’m not the first to observe this trend, as coaches have never trained robots. Fortunately for us, a principle has long existed in the world of strength and conditioning to help us embrace these individual changes that occur daily. In Mel Siff and Yuri Verkoshansky’s book, Supertraining, they describe cybernetic periodization as when “the original preplanned periodization scheme is regularly modified by subjective and objective feedback obtained from the lifter’s current performance state.”1

A coach who intentionally creates a culture of conversation and honesty encourages athletes to give subjective feedback. This type of feedback is a two-way street, as the sharp strength and conditioning coach can observe how an athlete’s body language may be “off” from what is typical. We’ve also never had more opportunities for objective feedback and evaluating athlete readiness than we have today through technology such as VBT, HRV, force plates, hand grip dynamometers, and sleep monitoring devices.

With this article, I’m offering a programming map and three distinct periodization models that I’ve had success with. Efficient maps and models offer wisdom to the decision-making process, and positive results from their use are conditional on the discerning application of the model (to ever-changing athletes); I hope you receive them in these terms. I’ve constructed my models from what I understand to be truthful about the human body and how the average body best responds to training. Models “written in pencil” assume they evolve, which can mean days and not years.

Credit to Mladen Jovanovic’s Strength Training Manual for delivering a resource that aptly explains how understanding the difference between small and large worlds allows us to employ models more successfully:

The real world is very complex and uncertain. To help in orienting ourselves in it, we create maps and models. These are representations of reality, or representations of the real world. Everything written in this manual represents Small Worlds—self-contained models of assumptions about how things work or should work. Although they are all wrong, some of them are useful (to quote George Box), especially as a starting point in your orientation, experimentation, and deployment to the Large World.2

I hope you find some of my models useful. As coaches, we ultimately will face the fork in the road where we have to commit to a direction of programming for our athletes, and because of this, we can’t live entirely in the abstract. We need to make decisions, and good models can influence our decisions for the better.

Mapping the Spectrum of Vertical Pulling Programming

My path to coaching an athlete to gain a more powerful vertical pull begins with a flow chart map to situate the athlete in the proper model. The flow chart allows the coach to execute short-term strategies with big-picture intent in mind—to become more powerful in vertical pulling. In general, we can administer these models with relative ease into most holistic strength and conditioning programs.

Recognize vertical pulling as a main movement during at least one session a week to avoid the pitfalls of downgrading it to an assistance exercise. Share on X

I ask you to consider, however, the merit in recognizing vertical pulling as a main movement during at least one session a week and avoid the pitfalls of habitually downgrading it to an assistance exercise. Our distinction between the two practically means we are more likely to place it at the beginning of the session if we value it as a main lift, and our athletes can perform the movement in a less fatigued state.

Programming for the Novice

A novice is an athlete who can’t perform one entire full range of motion (ROM) bodyweight vertical pull (and has no injury or pain concerns). These athletes often are unnecessarily and exclusively relegated to the lat pulldown machine or permanently stuck on the same assisted band variations that never intentionally and precisely increase in intensity. A starting point that’s an alternative to the former approach, which I’ve had success with, is systematically progressing through a six-week triphasic model that begins at lower forces-higher velocities and ends at higher forces-lower velocities.

The novice model undulates in volume session to session (time under tension and total reps), has linear increases in intensity every two weeks (the athlete pulling up more of their own weight), and includes just a hint of a conjugate element (switching the vertical pull variation via the grip, width, and bar thickness every six weeks). I’ve experienced great freedom because the elements I periodize don’t have to be mutually exclusive. I thank Greg Nuckols for his article on this very topic. He perfectly sums up this idea:

Westide is Conjugate Periodization! Such-and-such powerlifter uses Daily Undulating Periodization! Beginner or intermediate lifters should use a Linear Periodization program! It sounds like these are disparate concepts, when really almost all training plans weave all of these elements together to reach the desired end. They can do this because, as we touched on initially, training is organized on different time scales.3

Every two weeks, the athlete advances from a band assisting the entire ROM to ¾ ROM and then to finally ¼ of the movement assisted. This method follows what we know to be true about progressive overload: the athlete who progressively has to produce more force will get stronger over time and as the athlete receives less and less assistance over time—this method accomplishes this.

Check out my previous article, which has videos of the exercises I use in the assisted band category. You’ll see the varying degrees of assistance bungee bands can offer, depending on the distance the carabiners drop down from the bar.

The triphasic approach from Cal Dietz4 has been a game-changer for me. In this case, integrating the concepts provides the novice valuable time under tension. This athlete requires significant total work, and greater time under tension in longer eccentric and isometric contractions are very appropriate to teach them to own their positioning in a controlled manner.

Cluster training was impressively discussed by Carl Valle,5 so I won’t go into it here. I simply suggest that novices will benefit greatly from it. Although clusters are often thought of as an advanced strategy, they are just as important for weaker athletes as stronger ones.

The Tufano 2017 study6 really opened my eyes in this regard, as he found:

Intra-set rest provided in clusters allowed for greater external loads than with traditional sets, increasing total work and time under tension while resulting in similar peak power (PP) and % velocity loss (%VL). Therefore, cluster-set structures may function as an alternative method to traditional strength- or hypertrophy-oriented training by increasing training load without increasing %VL or decreasing PP.

The goal is to increase total work and time under tension, and clusters give novices these very things without compromising power production. An athlete who does clusters literally can get more work in than the typical 3 x 8-10 hypertrophy approach and perform high-quality reps. To me, it’s a no brainer.

Cluster training increases total work and time under tension for novices without compromising power production, says @RichterJeff. Share on X

To make matters more practical, when an athlete loses velocity with this movement, they often do leg kicking and jolting motions, as they generally lack the discipline to finely execute grinder reps occurring late in a set while under fatigue. The compromise of technical execution is a problem that coaches can get in front of. It’s a proactive approach that may very well reduce the risk of poorly performed reps, especially when we have a weight room full of athletes and our eyes are in a single place at a given moment.

To execute clusters for this population, Tufano again has key wisdom to offer from his 2018 study. 7 He showed that it might not be enough to have a velocity cut-off protocol where intra-set rest begins as speeds fall below a given number (he refers to this as contemporary traditional sets). In his study:

Each set during the traditional set (TS) protocol included as many repetitions as possible until two consecutive repetitions dropped below 90% MPmax, which was followed by 120 s inter-set rest. The design was identical for cluster sets (CS) but with an additional 20 s intra-set rest after every 2 repetitions. The number of repetitions performed, mean velocity, and mean power output, were analyzed using 2(protocol)*6(set) repeated measures ANOVA. The number of repetitions during CS (51.8 ± 14.4) was greater than TS (31.9 ± 3.7) (p = 0.001), but the average velocity (CS = 0.711 ± 0.069, TS = 0.716 ± 0.081 m·s-1; p = 0.732) and power output (CS = 630.3 ± 59.8, TS = 636.0 ± 84.3 W; p = 0.629) of those repetitions were similar.

He concluded, “These data indicate that cluster sets are a viable option for increasing training volume.” My experiences mesh with this study in that a session’s total volume can be compromised when you wait for reps to fall below a specified threshold, especially with a novice in vertical pulling (even when using a high number like 90% in the study).

Ironically, by attempting to limit slower reps with chin-ups and push-ups, we actually enable slower reps, says @RichterJeff. Share on X

Ironically, by attempting to limit slower reps, we actually enable slower reps—reps slower than the cut-off are still performed. I have found this concept to be true during the chin-up or pull-up when the novice knocks out reps well above a planned velocity point and then hits the wall and has poor peak power on the next rep. Diligence in increasing the frequency of intra-set rest maximizes the cluster effect, and there is most certainly an art to coaching this.

As an alternative to velocity cut-offs, I recommend using the final velocity or power of a rep in a cluster to serve as competition for the athletes to have with themselves. For example, if they complete a cluster, and the final rep of the set is “x” m/s, that’s now their target to not go below for the next clusters. Since the athlete most likely does not see the VBT readings, I call out the numbers (or have another athlete do so) and watch their intensity mount as numbers progressively lower as the cluster goes on.

This does two things:

  1. A coach with a big team doesn’t have to deal with the tedious task of having each athlete in the midst of the pull-up know exactly when to stop the set since they can’t see the VBT feedback screen.
  2. As referenced in my first article, we know that visual or verbal feedback enhances an athlete’s performance.

In a separate 2016 study of his,8 Tufano found that in the back squat, clusters of two were superior to clusters of four in peak velocity (PV), mean velocity (MV), peak power (PP), and mean power (MP) when averaged across all repetitions. For novices to achieve quality reps when using the full ROM assisted band, I’ve found that three often is the ideal maximal number of reps before intra-set rest should begin.

As always, make adjustments when necessary. And try to arrive at the total amount of work that is planned with the best rep speed possible while taking into account that training time is not unlimited; there’s certainly a balance between maximizing time in the weight room and producing high-quality repetitions.

My last note regarding novices is that I’ve found it unproductive to superset the vertical pull with vertical pushing because it greatly diminishes the quality of the next set. Instead, I have the athlete perform a “filler” exercise during inter-set rest. Depending on the athlete or team, this is often a low-intensity core/cuff exercise or a shoulder mobility filler. Even lower body lifts as a superset work. This way, a coach with a team doesn’t have athletes standing around between their turn on the bar. There’s also more high-quality work done in the vertical pulling aspect of the program.

At the end of the six weeks, the novice attempts to perform a full ROM unassisted bodyweight vertical pull. If they’re successful, they move on to the next phase. If not, they repeat the six-week phase with less assistance from the bands at each of the two-week intervals for the following mesocycle.

Programming for the Intermediate

Intermediate athletes can perform at least one bodyweight vertical pull but cannot pull 71% 1RM (bodyweight + load) with at least their bodyweight. Intermediates should not just target getting stronger; they also must get more powerful!

The fastest way to get an athlete to hit 71% 1RM with at least their bodyweight is by embracing conjugate periodization elements and changing the training stressor in each of the two vertical pull sessions per week. This way, they are training two different physical characteristics: high forces and high power outputs. Another conjugate element is switching out the vertical pulling exercise variation every three weeks. There are still triphasic considerations, undulation in volume session to session, and linear increases in intensity during the six weeks.

The fastest way to hit 71% 1RM with at least bodyweight: conjugate periodization elements & and change the stressor in both vertical pull sessions. Share on X

The first three weeks includes the assisted band variations for the highest expressions of power in the concentric portion of the lift, or what some may refer to as the dynamic effort day (it’s worth pointing out from my first article that the Munoz-Lopez study found power correlates more highly with velocity than force in the pull-up). The isometric and eccentric focus is always on the descent after an explosive pull-up.

The max effort day offers no assistance and has the athlete perform bodyweight or greater vertical pulls at their 2RM starting in week one. The goal is to add 2.5 lbs of additional load each week. I recommend that these athletes use added weight attached to a belt rather than holding a dumbbell between their feet. It’s generally easier to find a 2.5 lb plate to slip onto a chain than DBs that increase by 2.5lbs.

By the time the athlete gets to weeks 4-6, I find it a great time to incorporate medicine ball training in the form of slams to achieve faster velocities than the assisted band reps can offer. I contrast the medicine ball slams after the higher force max effort pulls. Carl Valle made some outstanding points about medicine ball training when he called for a “tighter and more-specific strategy”9 for their use. The contrast effect is exactly that in this instance—we get robust strength qualities and the peak velocity movement in the same session.

The Ignjatovic 2012 study10 showed that medicine ball training has its place in a holistic program that seeks to improve power. When incorporated with a regular training program, “applied medicine ball training improved peak power during bench and shoulder press at 30 and 50% of 1RM” compared to a control group that performed everything the same except the medicine ball work.

With weighted pulls now occurring twice a week instead of once, the athlete receives more focus on the maximal strength qualities and performs a different vertical pull exercise in the last three weeks than the first. I’m a big fan of these subtle changes to the max effort exercise variation, as they tend to recruit a more diverse pool of muscle over the long term versus staying with one vertical pull variation.

For example, the lower traps have a peak MVC score of 87.2 in the wide pronated grip pull-up. In the close parallel grip, the peak score is 69.1.11 The variation in recruitment patterns is important for the traps, rhomboids, and biceps to develop and assist the lats consistently.

Just like weeks 1-3, the goal is to increase the amount of weight lifted at each rep scheme in weeks 4-6. This is the linear component at work. For the same given volume, seeking to increase force capabilities for as long as possible until plateauing is low hanging fruit. During this time, it’s critical to have access to 0.5 kilos and 2.5 lb plates.

At the end of the six weeks, the athlete will see if 71% of their 1RM (bodyweight + load) is at least their body weight. If not, they repeat the 6-week mesocycle. If successful, they move to the final phase and model.

Programming for Advanced Athletes

Advanced athletes are those whose 71% of 1RM is at least their body weight. William Wayland did an excellent job teaching his approach to supramaximal training,12 and my use of these techniques on the advanced athlete is undoubtedly influenced by his work.

An athlete who is significantly strong and powerful in vertical pulling, as demonstrated by the ability to hit 71% 1RM with at least their body weight, can still get stronger and more powerful. But their improvements in vertical pulling—like any other exercise—often plateau in both strength and power gains. With that in mind, it’s important to find a way to stress the body more significantly than just weighted pulls emphasizing concentric components and eccentric lowering at submaximal weights.

That’s where supramaximal eccentric and isometrics come in. As William wrote:

Compressed intensive training is a period in which we apply the greatest stimulus to accumulate the desired response in the shortest time possible—this is where we apply supramaximal training. Supramaximal training is one of the approaches that excites muscular physiologists, as it leads to rapid adaptations and a reduced need for the repeat exposures we get from the same contraction focus at submaximal loads. Time, as a commodity, is always in short supply. It’s not for the faint of heart, nor the inexperienced.

During the second session each week after the supramaximal reps for both the eccentric and isometric movements, I like to contrast with singles with a concentric focus. Adding the band-resisted reps for the contrast work is a great way to develop explosive pulling abilities through the entire ROM. The benefits of accommodating resistance are known widely,13 and I tend to find their implementation in a vertical pulling program more appropriate for athletes without an explosive pulling deficit.

After two weeks spent on both eccentric and isometric supramaximal work, deload weeks are appropriate. These set up the athlete nicely to arrive at weeks 7-8 ready to target some potentiation effects from the concept of wave loading to see peak power capabilities improve. With a very similar structure to the Chiu 2012 study,14 each wave consists of multiple sets of pulling where we increase the resistance for each set until the completion of a wave. The athlete then lowers the intensity and performs two vertical pulls at 71% 1RM to take advantage of PAP.

In his study, Chiu saw a 5.77% vertical jump increase at the midway testing point and a 5.90% increase at the end of the second wave due to the potentiation effects on vertical jumping from full snatches. After testing peak power at 71% 1RM pre-, mid- (after first wave), and post- (after second and final wave), I’ve seen an average improvement of 2.5% peak power (watts) after the first wave and 1.8% after the second wave in the 80%+ wave protocol and 2.2% and 2.1% for the 50-80% wave protocol.

Although I need to obtain a larger sample size, my initial findings for wave loading in the pull-up suggest wave loading does work to increase peak power in athletes who are advanced in vertical pulling ability and more so after the first wave than the second.

I hope this provides you with a practical resource to situate your athlete in an appropriate model so your athletes can ultimately achieve greater levels of power in vertical pulling.

Golfer Swing

Overspeed: Facts and Fallacies of Training Beyond Maximal Velocity

Blog| ByChris Finn

Golfer Swing

Club head speed is a hot topic in golf, and it should be. There is a very strong relationship between how much money PGA Tour players make and how far they can hit the ball. Club speed is a skill that gives golfers an edge at every level, and it is therefore heavily sought after. Phil Mickelson and Brooks Koepka are both known to say that they would rather have an 8 iron from the rough than a 5 iron from the fairway. This is the common mentality on the PGA and LPGA tours.

Because of this, there are many companies coming out with speed products in the golf space, and they are all marketing those products as the quickest and best ways to pick up speed. One of the industry leaders is SuperSpeed Golf, which has more than 650 touring professionals using their tool, demonstrating the popularity of this type of training.

Some of the companies focus on improving technical skills to maximize speed. Others, like SuperSpeed, focus on taking advantage of the nervous system gaps that exist for most untrained golfers and helping them maximize their speed from that angle. They do this by utilizing what has become known as overspeed training.

Technically, this is nothing new, as overspeed has been used and studied in sprinting for years, and the Russians even used it 50–60 years ago for their throwing athletes. Since then, over-weighted and under-weighted balls have become quite the hot topic in baseball and cricket as those two sports’ form of over/underspeed training. Heavy and light bats are a big discussion point when talking about bat velocity in baseball as well.

While there has been zero research published on this topic for golf (at least that I could find while writing this article), there are a number of articles published in the track and field, baseball, cricket, and handball spaces that I took a look at to better understand the context of this topic as objectively as possible. What follows is the result of hours and hours of review of the available literature.

In addition, we have completed two randomized in-house clinical trials at Par4Success, lasting six and eight weeks respectively, and seven years of clinical and strength and conditioning work with thousands of golfers longitudinally at this point. In the interest of this article not being 10,000 words long, I have only included in the citations the articles with the best methods and those directly quoted. The studies I cite below refer to another 50 or so further studies if you really want to dive in. Buckle up…here we go!

Why Care About Overspeed?

The world of strength and conditioning features a number of well-accepted, researched ways to gain speed and ultimately increase an athlete’s power. It is widely accepted that taking any relatively untrained individual and introducing them to foundational strength training will improve their speed, among other desired athletic attributes, including power output. As an athlete increases in strength and skill in their sport, there is the idea that they will reach a point when they are “strong enough.” At this point, the speed of contraction starts to become more of a focus for gains that are most transferable to sport. This is where much of the recent velocity-based training research has been focused, particularly for professional and elite-level athletes.

A lot of this research is still new to much of the field even though early research was done years ago. That being said, during this progression of athletic development, there is also a concurrent focus on improvements in technical efficiency and equipment optimization. At the end of the day, all parts of the puzzle operate with the aim of creating as much power expression in sport as safely and sustainably possible.

Knowing this, you might ask: Why do I even care about overspeed training if I know my athletes will improve in speed and power numbers by sticking to the tried and true? Once they get “strong enough,” I will just jump into VBT, right? Is there really any value in having them swing or throw heavy and light stuff hundreds of times a week? That will increase the load on my athlete’s nervous system and potentially increase risk for injury—is it really worth it? I asked myself these same questions, which is why I am taking the deep dive into this rabbit hole with you.

The specific question we have in the golf world is: “Does overspeed training fit into the context of training golfers to produce more speed with maximal efficiency and safety, and if so, where?” I want to emphasize safety and efficiency here. Gaining speed is easy. Figuring out how to do it efficiently and without injury is the hard part, especially with the presence of high volume protocols, which are accepted as the gold standard in the golf performance space.

Does overspeed training fit into the context of training golfers to produce more speed with maximal efficiency and safety, and if so, where? Share on X

You can take any untrained individual, tell them to do anything fast, and they will move faster—this wouldn’t surprise or shock most strength coaches. Research has shown clearly that simply having golfers perform three countermovement jumps before they swing will increase their club speed immediately. Nervous system potentiation is not rocket science, and there is plenty of literature on it. Think “newbie gains” in the gym.

That being said, the real questions that I will answer here are these:

  • Once initial adaptations occur, is there any merit to this type of training long-term?
  • Do the initial transferable gains of overspeed training to sport outperform those of traditional strength and conditioning?
  • Can we use overspeed training as a substitute for traditional strength and conditioning?
  • Are long-term results (1+ years) optimized if we combine overspeed training with traditional strength and conditioning versus using it in isolation or not using it at all?
  • What sort of frequency, protocols, or volume should we utilize for maximal benefit, minimal risk of injury, and minimal system load?
  • Do any of the potential gains of overspeed training (either long-term or short-term) outperform the traditional methods that are proven to transfer to sport?

Clearly, there are a TON of questions to answer and most of these have been answered, in theory. Few, if any, have answers rooted in scientific truth.

What the Sprint Research Says

Overspeed training in the sprinting world comes from the idea that if you increase speed, you need to either increase stride length or frequency. Every athlete will have an anatomical limit to their stride length, obviously. But, from a training perspective, large gains may be made in the frequency realm.

In their study, Behrens, et al.1 discussed downhill sprinting versus high-speed treadmill sprinting, as well as resisted sled running and hill sprints. Throughout their review, they gave the pros and cons of every popular method, and they pointed out that there is a point of diminishing returns in terms of utilizing too much of an incline or downhill grade, as well as going too heavy on the sled loads. Use just the right amount of slope and get the effects that you want; use too much and you run the risk of changing the technique of the sprinter in question.

These findings are similar to those of a completed Par4Success study showing that, if a golfer swings an implement that is too light or too heavy, their kinematic sequence will dramatically change from what is considered ideal or normal for them under playing conditions (more to come on this later).

If we focus on the overspeed element, Dintiman and Ward3 cited that a 1–2.5% downhill grade was the most a sprinter could utilize without producing a braking effect, while another study by Plisk4 recommended a 3- to 7-degree grade, and yet another study found that 5.8 degrees produced the fastest results. We further see suggested in the research that declines greater than 3% can lead to greater braking effects with excessive stride lengths and without increases in stride frequencies.

So, as you can see, there is a lot of conflicting research on downhill sprinting that presents many discrepancies in recommended gradients to maximize efficiency. The water is a bit murky in terms of the ideal gradient, but it certainly appears that training for increased stride frequency with a downhill gradient produces a positive effect on a sprinter’s speed. That being said, I think you would be hard-pressed to find a sprint coach who only utilizes this type of training in isolation without traditional strength and conditioning methods, which have no question as to their efficacy. I wish the same could be said in the golf coaching world.

What the Baseball Research Says

There have been a number of different studies on over-weighting and under-weighting bats and balls for swinging and throwing in baseball. One study showed that dry swing warm-ups are a more effective means of enhancing bat speed outcomes when performed with a standard-weight bat versus heavyweight and lightweight bats. Another study found that actually hitting a ball in live batting practice produced better results than just dry swings—again, some murky conclusions to be drawn.

When thinking about how the weight of the implement can impact kinematic efficiencies and sequencing, this was the same result seen in the 2018 study by Par4Success. It is accepted that the ideal efficient kinematic sequence is initiated with the lower body, followed by the trunk, and then by the arm and club, respectively.

With a 20% lighter club, each golfer’s arms and club measured with the K-Motion 3D system initiated before their lower body and torso in a significant manner when compared to the golfer’s regular swing with their standard driver. This results in a more upper body driven swing, which is inefficient, but more importantly, the exact opposite of the sequence that many of these golfers exhibited when they swung their normal club.

When measuring the kinematic sequencing while a golfer was swinging a heavy club (10% heavier), there was an increased x-factor (separation between upper and lower body at impact) beyond PGA Tour norms and beyond what was seen with each golfer’s normal club.

As seen with the dry swing study, both heavier and lighter clubs lead to much different results in speed outcomes. You should consider kinematic sequence impact when thinking about prescribing these types of protocols.

DeRenne and colleagues10 and Southard and Groomer7 concluded, in their respective studies, that the very heavy commercial donut ring, a heavy 51-ounce bat, and the very light 23-ounce bat used in warm-ups decreased game bat velocity by 5 mph.

This result is similar to what Par4Success found in golfers in their 2018 study when looking at only completing overspeed training with a heavier golf club. The golfers in this randomized group also saw a decrease in their swing speeds.

The research is similar to a 2018 Par4Success study where golfers who only completed overspeed training with a heavier golf club saw a decrease in their swing speeds. Share on X

Montoya et al.9 reported that swinging a light (9.6-ounce) or “normal” 31.5-ounce bat produced the highest bat swing velocities compared with a heavy (55.2-ounce) bat in the on-deck circle. Furthermore, Southard and Groomer7 reported that after warming up with two heavy-weighted bats of 34 and 56 ounces, respectively, bat swing velocity significantly decreased, while moment of inertia significantly increased.

The results with a 6–10% lighter club in both the 2018 and 2019 Par4Success studies, which produced speed gains, seem to support these findings. Montoya, et al.9, however, did find a different result with the significantly lighter club compared to the 2018 Par4Success study. Montoya saw an increase in speed, while Par4Success saw the group that only trained overspeed with the 20% lighter club lose club speed, on average.

Southard and Groomer7 concluded that baseball batters should warm up with their respective standard game bat and using a bat with a larger moment of inertia will reduce bat velocity and change the batter’s swing pattern. Montoya, et al.9 also suggested not to swing a heavy bat in the on-deck circle because it produced the slowest bat swing velocities. These results and conclusions support, in part, the findings of DeRenne and colleagues10, which suggested that players should warm up by swinging bats that are ±12% of their standard game bat weight (30 ounces) before game competition.

In summary, the big takeaway findings from much of this research in baseball are from Szymanski, et al.14 In terms of the take-home points, the “big hitters” were:

  • One-hundred swings daily for three times a week will increase bat speed in untrained individuals.
  • Swinging a bat that is within 12% of the game day bat’s weight will increase a player’s speed, while swinging one that is too heavy or too light will hurt a player’s speed.
  • The players with the greatest strength, power, and lean body mass had the greatest bat swing and batted ball velocities.

I will get into the reason these points are important for golf. But first, there were a couple other interesting studies in handball and cricket.

What the Cricket and Handball Research Says

Cricket and handball have also had a few studies looking at over-weighted and under-weighted balls in the past few years. One of the earlier studies in cricket by Petersen, et al.13 looking at fast bowlers found that a 10-week program of modified implement training was not effective at increasing the bowling speed in its test subjects. However, this study was performed on senior-level club players and did not include any strength and conditioning measures. The likely question here is: “Did these subjects have enough strength to begin with to benefit from overspeed training?” This is a common question in the golf sector as well.

In the more recent study by Wickington12, they followed a similar approach and did not include strength and conditioning. Their conclusion was that modified implement training “might” be productive in producing speed increases—not very convincing. But again, we are viewing these results with blinders on and not assessing any other aspects of the athletes.

Finally, a four-week study on elite-level handball players by Ortega-Becerra, et al.11 found no significant improvement in velocity after a program focusing on throwing balls with different techniques and weights. This suggests that with higher level athletes (the average player in this study had 11 years of experience), doing only an overspeed and underspeed training program was not sufficient in that short amount of time to produce the results desired.

Similar to track and field and baseball, it is difficult to pull out stone-cold scientific facts from this research. There has just not been enough convincing work done with large enough samples to have a definitive answer. That being said, there are a number of common threads and they should be extrapolated to golf.

Answering the Initial Questions for Golf

There are a number of common questions asked about overspeed training in golf. There are also a number of important ones that I need to address that aren’t necessarily at the front of people’s minds. Here are some of the more common and important ones.

Once initial adaptations have occurred, is there any merit to overspeed training long-term?

None of the studies that I was able to find discussed longitudinal improvements or the causation of those improvements. This is the hardest type of research to do, which points to the lack of evidence. If you speak with most strength and conditioning coaches, it is relatively accepted that periodizing athletes throughout the year with higher and lower amounts of neural stress clearly works for long-term improvement, and you cannot constantly train high neural load all year, every year.

I recommend a well-rounded approach to training using both strength and conditioning, along with nervous system-focused exercises. Constantly completing overspeed training throughout the year without periodization to focus on strength building or nervous system recovery would seem to be inappropriate if we look at other forms of nervous system training. That being said, we have seen it be very useful, particularly in the 40+ population, to employ overspeed training in conjunction with the conversion to power phases or other phases focused on speed generation to produce swing speed gains year after year, well into a golfer’s 70s.

Do the initial gains of overspeed training outperform those of traditional strength and conditioning?

Talking specifically about golfers, look at the Par4Success studies from 2018 and 2019 and compare the speed gains in these time frames to Par4Success’ longitudinal data when golfers were involved in a strength and conditioning program for golf but not using overspeed training. When we look at these numbers, there appears to be a bigger jump with the addition of overspeed training than solely with strength and conditioning, by almost threefold. In six and eight weeks, respectively, the average gain was just around 3 mph, which is three times the average gain of 1 mph for adult golfers over a 12-week period with just traditional strength and conditioning.

The reason for this is likely that, neurologically, many golfers underperform what they are physically capable of, and the acute spike in fast, golf swing movements “wakes up” their systems. When I look at our database, I see that the golfers who tend to do the best with overspeed training are initially the ones who perform much lower on their speed percentiles relative to their power percentiles that are correlated to club speed. These are the golfer who you see add 10 mph to their club speed in 12 weeks.

Golfers with lower power percentiles relative to their swing speed percentiles aren’t ideal candidates for overspeed training as they don’t have the strength base to benefit. Share on X

Golfers who have lower power percentiles relative to their swing speed percentiles are not ideal candidates for overspeed training, as they do not have the strength base to benefit. These are the ones in the Par4Success database who fail to improve at all or significantly beyond what would be expected with traditional strength and conditioning.

Can we use overspeed training as a substitute for traditional strength and conditioning?

No—emphatically, no. It would be irresponsible to use overspeed in isolation to train golfers for increased speed. First, increasing how fast someone can swing without making sure they have the strength to control that speed can set someone up for injury and failure. Secondly, if overspeed training is appropriate for a golfer (they have full rotational mobility and their power percentiles are greater than their swing speed percentiles based on their age and sex), you need to be sure to increase their strength as their speed increases. Failure to do so will put the golfer at risk for potential injury if their speed is allowed to outpace their strength.

Like all nervous system training tools, if you utilize overspeed training in the right scenario with the right person, the gains can be quick and impressive. I have seen 10+ mph in under 10 minutes in the right situation. This leads to a lot of hype and excitement around it in the social media training world and, unfortunately, a lot of misinformation, which I hope this article helps to clear up.

Are long-term results (1+ years) optimized if overspeed training is combined with traditional strength and conditioning versus in isolation or not at all?

It appears that combining overspeed training with traditional strength and conditioning increases speed gains compared to either modality alone. This conclusion is based on the results I have seen with our longitudinal programs that use overspeed training periodized with an athlete-specific strength and conditioning program and sport-specific training (i.e., technical lessons, equipment, etc.—not medicine ball throws or cable chops).

In order to keep decreases in club speed to no more than 3–5% during the competitive season (as is the normal amount in Par4Success’ data), it is imperative to keep golfers engaged in an in-season strength and conditioning program focused on maximal force and power outputs. By minimizing this in-season loss, it assures that we see gains year over year.

It is unclear if overspeed training in conjunction with strength and conditioning during the season further decreases this standard loss due to nervous system fatigue, but this would be a great area for future research.

What sort of frequency, protocols, or volume should I utilize for maximal benefit and minimal risk of injury?

Most of the studies specifically on swinging that I was able to find looked at about 100 swings at three times a week (baseball). The SuperSpeed protocols that are the most popular in the golf world follow a similar volume recommendation. It is a concern, especially with untrained individuals, that adding 300+ maximal swings per week might increase the risk of injury due to the incredible increase in load. This is especially true for the amateur golfer who only plays on the weekends and does not engage in a strength and conditioning program, as this is a significant volume increase from their baseline.

The Par4Success studies in 2018 and 2019 found no significant difference in swing speed gains between high volume protocols and a lower volume protocol, which required only 30 swings two times a week but also required a two-minute rest between every 10 swings.

There need to be more studies looking at this beyond just these two. I would recommend, specifically in golf, not to engage in high volume protocols, as they appear to increase the load on the athlete significantly without increasing speed gains. Having utilized this lower volume approach beyond the two randomized studies, we continue to see similar results.

Specifically in golf, I’d recommend not to engage in high volume protocols, as they appear to significantly increase the load on the athlete without increasing speed gains. Share on X

Do any potential gains from overspeed training outperform the traditional methods that are proven to transfer to sport?

This is a hard question to answer, but based on the golf-specific findings and the other findings across all of the sports mentioned, it would not appear that overspeed training is superior to any one training method, but rather a tool to use in conjunction with other proven methods. The key here is to assess your athletes and look to implement this type of training in golf when you know that mobility is not an issue and their physical ability to produce power is higher than their ability to generate club speed. In this scenario, overspeed training can be a game-changing tool. In the wrong scenario, it can be a nail in a golfer’s coffin.

What This Means for Golf

As you digest all of the research, you start to see how murky the waters really are around these ideas. It is no longer surprising why there tends to be so much heated discussion around these topics. With minimal science-based fact, there is a lot of room for emotional beliefs to take hold.

In the end, I think Szymanski, et al.14 hit the nail on the head with their highlight of the clear relationship between the fastest bat speeds occurring with the stronger and more powerful players. We need to help golfers become stronger and more powerful with traditional strength and conditioning techniques to maximize performance and longevity and reduce injury likelihood. From here, overspeed training can become an amazing tool to implement at different times during the year at lower volume and system loads than are currently being used industry-wide.

To be clear, it is my opinion that overspeed training works in both the high volume and low volume protocol formats based on the available research and my firsthand training experience of more than 1,000 golfers. There is statistically no difference in outcomes between high volume overspeed protocols and low volume ones. Because of this, high volume protocols are unnecessary and a waste of golfers’ time and energy when they can see the same results with 66% fewer swings. High volume protocols also put unnecessarily high amounts of maximal stress on golfers’ bodies, putting longevity at risk, especially when they are carried out in the absence of a customized strength and conditioning program for golf.

A “properly designed golf performance plan” does not only include one single element of overspeed training or solely traditional strength and conditioning. It is a plan that is periodized throughout the year for an individual golfer that includes soft tissue care, mobility, stability, strength, speed, and power development, both in general athletic and sport-specific terms.

The golf swing is an incredibly powerful movement and requires significant rest in between swings for physiological recovery to occur. Because each swing happens in seconds, the glycolytic system is one of the major energy systems required for the athlete to be explosive. The problem is that this energy system requires a LOT of rest between bouts in order to recover fully. If you don’t allow for full recovery, each swing becomes a maximal effort of 90%, then 80%, then 70%, and so on. Effectively, you trade quality for quantity, and each subsequent swing is less effective than the previous one.

Based on available research & my experience with more than 1,000 golfers, I believe overspeed training works in both the high volume and low volume protocol formats. Share on X

In order to combat low-quality reps, it is necessary to take rest breaks with 5–10:1 rest-to-work periods. If these are not adhered to, the effectiveness of the training suffers. This is another reason why low volume protocols would be preferable to high volume ones. To take these necessary rests, a high volume protocol would take more than an hour. With the lower volume protocols, you can still keep the work time to 10 minutes.

In summary, the golf world needs more randomized control studies that expand on this study to further validate and improve the science available to the greater golf performance community.

A Simple and Systematic Approach to Monitoring Fatigue

Blog| ByWill Ratelle

Volleyball Serve

Managing training load has become an increasingly prevalent concern in athletics, for sport coaches as well as strength and conditioning coaches. I work with an NCAA volleyball team, and it is imperative to monitor and manage fatigue for a number of reasons: reducing injury risk; improving performance in general; specifically maximizing performance for key matches; and managing the overall readiness of each team member individually, as well as the team as a whole. Off-season training is different, but this article will discuss a method (and justifications) for measuring fatigue during the competitive sport season.

Addressing the Specific Demands of a Sport

Jumping is a critical movement in volleyball. Across practices, matches, and training, volleyball players jump more frequently than athletes of many other sports. Intense hops, bounds, and depth jumps require the highest nervous system demand and generally necessitate 2–3 days of recovery before training again.1 Unfortunately, college volleyball players are not afforded the luxury of taking 2–3 days off between practices, games, or strength and conditioning training sessions.

For volleyball, jump performance is a useful metric in helping coaches make adjustments to the training needs of the athletes, explains @will_ratelle. Share on X

Tracking fatigue—both acute and chronic—is important to training for the maximum performance at the critical time. For volleyball, jump performance is a useful metric in helping coaches make adjustments to the training needs of the athletes.

Constraints in Collegiate Sports Training Programs

Ideally, strength training would occur when an athlete is rested and recovered from practice or competition. NCAA sports, however, have unique circumstances that must be addressed when developing practice plans and training sessions. Every team must follow the same maximum practice/training hours rules per week, but each team will have different situations regarding:

  • Practice time of the day
  • Training time of the day
  • Travel schedule
  • Class schedules
  • Age/gender of athletes

The volleyball team that I work with consists of 18- to 22-year-old females, with practice times at 6 a.m. Our weight room training sessions occur immediately after practice ends, with a 10-minutes transition period from the court into the weight room. Training after practice isn’t ideal, but it’s the time slot available. We share facilities with both the men’s and women’s basketball teams, so we all have to work together to get our practices and training sessions in.

The team travels at inconvenient times, sometimes early in the morning or late at night, and sometimes they’ll be out of town for as much as six consecutive days. Every college student athlete has to go to class, and some have more rigorous class schedules and workloads than others. There are 15 players on the volleyball team, and there are many factors that cannot be controlled that may or may not impact their performance.

How to Use Squat Jumps to Measure Fatigue

Our program measures three squat jumps at the beginning of each conditioning training session using the Just Jump Mats. A squat jump is defined as a vertical jump at a self-selected depth without a counter movement. The athlete gets into a jumping stance, drops into a self-selected squat depth, holds for a count of “one one-thousand two,” and then jumps from that position without dipping down again. A squat jump height is usually lower than a countermovement jump.2


Video 1. A single squat jump performed from self-selected squat depth and using proper form.

We have our baseline jump height for each athlete that is recorded at the beginning of the pre-season. We get three jumps on the first two days, for a total of six jumps. We take the average of these six jumps, calculate the coefficient of variation of the six jumps, and multiply the coefficient of variation by 1.1. Then we subtract that number from the average of the six jumps. The resulting value is what we call the athletes’ caution number (caution number = jump height average less coefficient of variation x 1.1).

Caution Number Table
Table 1. How we calculate each athlete’s “caution number” based on a formula from six pre-season jumps.


Throughout the season, we take daily measures of the athletes’ squat jump heights and compare these to their caution numbers. The athletes jump two times: If both of their jumps are higher than their caution number, then the athlete follows the training plan as scheduled. Their jump results indicate that they are in a good enough state to train hard.

If one of the two jumps is under their caution number, the athlete will jump a third time. If their third jump is higher than their caution number, the athlete will follow the training plan as is, but we will monitor them a little bit more closely. If both jumps are under their caution number, we make the necessary adjustments to their training plan. Generally, we reduce volume, and we possibly reduce load or consider making additional adjustments to other training variables.

A specific example of how we’ve adjusted training based upon the athletes’ jumps occurred at a time when we had most of our players jumping below their caution number. We were scheduled to perform four sets of two on cleans that day, and three sets of three on back squats. We ended up cutting out all of the sets of cleans and just got right into our squatting sets. The following day, our jumps went back up to their normal range.

We have access to Tendo Units as well, so when we have only a couple athletes jump under their range, we can give them a speed range to hit that is a little bit faster than what is planned for the day. This will lead to lightening the load, but the intent should still be there because the athlete is moving the bar as fast as they can. The good thing about having a small team to work with is that we can more readily individualize the training program.

One problem that we sometimes see when having the athletes perform the squat jump is that after they pause in the bottom position, they want to quickly dip a little bit lower and innately turn it into a countermovement jump. When that happens, we just have them perform another trial and remind them not to dip a second time.


Video 2. A squat jump performed with improper form, with a dip that mimics some of the qualities of a countermovement jump.

The Jumps as Metrics: Vertical, Approach, and Squat

A vertical jump is a standing countermovement jump for maximum height with no approach steps, while an approach jump is a jump for maximum height using self-selected approach steps prior to the jump. Typically, volleyball programs test the vertical jump and approach jump to measure improvements pre- and post-macrocycles in training. These two types of jump tests have been shown to be correlated to other athletic performances, such as sprinting ability and change of direction ability.3

The squat jump is a standing jump for maximum height with hands on hips at a self-selected squat depth with no countermovement. The squat jump is a common test for researchers with a force plate that can measure:

  1. Takeoff velocity
  2. Rate of force development
  3. Starting gradient (1/2 peak vertical force divided by time at 1/2 peak vertical force)
  4. Acceleration gradient (1/2 peak force (time to peak force minus 1/2 time to peak force))
  5. Jump height
There are many advantages to using the squat jump in a monitoring program over the countermovement jumps, says @will_ratelle. Share on X

There are many advantages to using the squat jump in a monitoring program over the countermovement jumps. There is less intra-subject variation in performance in a squat jump compared to the countermovement jumps, which allows for a smaller co-variance and, therefore, a smaller window of performance and more reliable measurements. Also, psychologically, volleyball players are not worried about seeing low jump heights on the squat jump because they know that it is supposed to be lower than a countermovement jump. Because they do not jump as high, the exercise itself is less intensive compared to the countermovement jump.

Since jumping is a skill that is part of every volleyball game—and research suggests there is a strong correlation between vertical jump performance and fatigue and athletic performance in other skills—we measure it daily to get feedback and adjust training.

You could argue that using a countermovement jump would be more useful to test volleyball players because it is more specific to the way they jump on a court, it includes the stretch shortening cycle, and it includes a buildup of muscle stimulation, as well as allowing elastic energy to contribute to the performance.2 One study compared the differences between different types of jumps and found that concentric neuromuscular activity does not seem to vary when the subject is attempting to maximally jump, while eccentric neuromuscular activity does vary depending on factors such as landing, speed of movement, etc.4 Utilizing the SJ eliminates all of the other noise that may or may not contribute to jump height performance.

However, having a higher squat jump may have just as much or even more value, as it reflects the capability to reduce the degree of muscle slack and quickly build up stimulation, which is important to high-intensity sports such as volleyball.2 Another point to consider is that it takes approximately .4 seconds to produce maximum force5, and the squat jump reduces the amount of time allotted for the athlete to produce force, possibly indicating the fatigue or freshness of their neuromuscular state of well-being.

A high squat jump reflects a capability to reduce the degree of muscle slack and quickly build up stimulation, which is important to high-intensity sports such as volleyball. Share on X

Due to time and the number of players, it is not logistically feasible to track all three jumps for all players on a regular basis, so we just use the squat jump.

Sharing Our Data with the Coaching Staff

We track all of the athletes’ squat jump trials throughout the season and periodically share our findings with the coaching staff. We provide this in both table and chart formats to easily visualize trends.

Table-Team-Avg-SJ
Table 2. The team average for jump heights on our volleyball team. August 6 was the first day of the pre-season, after we had gotten their six jumps’ average two days prior. August 24 was the last day of the pre-season. The team had the 25th off, and on the 26th, their jump heights were almost back to their first-day average. They had a scrimmage on the 27th, and you can see that their jumps took a dip on the 28th.


The coaching staff appreciates actionable data that they can implement into their practice and game preparation as they consider the athletes’ physical status and fatigue. On top of the SJ tracking, the athletes also fill out a session Rating of Perceived Exertion (RPE) after every training session we do, along with a soreness grade on a scale of 1–5. Some may not like using RPE, but if you can establish trust with some of the older athletes or the captains on your team, it can be a useful tool.

RPE-Graph
Table 3. This chart shows the RPEs and Soreness that the players fill out on their workout card daily.


As an additional factor in our athlete monitoring program, we also track body weight: not necessarily for fatigue management, but as a way to hold the athletes accountable to make sure they get enough food in throughout the day. As I mentioned above, our team practices at 6 a.m.—knowing how college students sleep, it is unlikely that they wake up early enough to make breakfast. Most of them probably roll out of bed at 5:30 and head straight to the gym without eating more than some toast or a protein bar.

We track body weight, not necessarily for fatigue management, but as a way to hold athletes accountable for getting enough food in throughout the day, says @will_ratelle. Share on X

Tracking body weight helps reduce some of those habits when the scale shows that they are down 6 pounds from the previous week. It is also interesting to check if there are any correlations between body weights and jump heights on a daily or weekly basis. We haven’t noticed anything as of now, but it can’t hurt to continue collecting data—perhaps I’ll learn more about what to do with the information down the road in a way that can help enhance our program. The system we have now works for us, and hopefully we continue to grow and expand our abilities on this subject to keep improving.

We are fortunate enough to have access to two pieces of reliable technology: Just Jump mats and the VERT monitoring system. The players wear the VERT every day during practice, and it provides live recordings of jump counts, jump heights, landing impacts, etc. Our volleyball staff finds VERT very useful during practice and even during games. If you do not have access to this type of technology, you could always just use a Vertec or a G-Flight by Exsurgo Technologies. It is all up to what resources you have access to and what your situation is.

We previously tried to monitor our athletes’ fatigue using the Tendo Unit. If the athlete doesn’t hit the targeted velocity on their first set, then load gets reduced. There are, however, two problems I see with that method. First, if we only use the bar speed, we only reduce absolute load, when in reality it is probably best to reduce volume instead. Second, our athletes play sports, they are not powerlifters, so their bar speed will have much more variation from rep to rep since they are not necessarily elite barbell athletes.

So, it is a tool—and a useful tool—but we are finding more success using the squat jump at the beginning of our sessions right now. The goal from here on out is to continue building on what we are doing: making ourselves better to improve the performance and the lives of the athletes that we train.

Coaching Science Fallacies

Busting the Fallacies of Sports Science with Jared Fletcher

Freelap Friday Five| ByDr. Jared Fletcher

Coaching Science Fallacies

Dr. Jared Fletcher is currently an assistant professor in the Department of Health and Physical Education at Mount Royal University in Calgary, AB, Canada. There, he teaches courses in exercise physiology, biomechanics, and statistics. His current research interests lie in examining the energetic implications of muscle-tendon interaction during running and walking and physiological methods to optimize performance in athletes. Specifically, Dr. Fletcher is interested in how measures of heart rate variability and skeletal muscle fatigue can be used to best prescribe training intensity and duration in elite and recreational athletes.

Freelap USA: Potentiation is popular with coaches, but social media often tends to inflate and misconstrue what really happens physiologically. Can you identify mistakes you see in terms of coaches who assume they use PAP but do not actually perform such an event?

Dr. Jared Fletcher: Coaches and sports scientists have long thought that PAP (post activation potentiation) contributes to improved human performance. This probably began with a popular (and excellent) review by Digby Sale in 20021, highlighting what muscle physiologists had known for some time: Muscle twitch force, or low-frequency force, increases following a conditioning contraction like a maximal voluntary contraction, the mechanism of which is myosin light chain phosphorylation. Coaches and sport scientists then took this phenomenon to imply that if contractile force could be improved following these conditioning contractions, then so could sport performance. An athlete’s warm-up should, therefore, incorporate these conditioning contractions to try to elicit PAP to improve subsequent performance.

Many human studies have been designed to try to demonstrate this. For example, athletes perform two types of warm-up: one without a type of conditioning contraction and one with these contractions followed by a performance outcome. When the performance outcome is improved with the warm-up containing the conditioning contractions, the mechanism is said to be PAP.

These types of studies typically make several key assumptions or errors, which are well described in a paper by MacIntosh et al.2. [Full transparency: Brian MacIntosh was my graduate supervisor, but I was not involved in the writing of this paper.]

  1. PAP, at the level of the muscles, is often never measured. That is, the response to a single, electrically evoked twitch is not quantified, so there is no way to know whether muscle twitch force increases.
  2. Confounding factors to the conditions, such as muscle temperature, blinding of the subjects, and/or the study investigators, are often not accounted for.
  3. Performance is often measured at times when you would not expect PAP to be present. PAP dissipates quickly following a conditioning contraction, but performance is often measured 10 minutes or more following the contraction.
  4. PAP is thought to be the mechanism behind improved performance, but perhaps it is as simple as the conditioning contractions improving the warm-up, so performance is improved simply because the athlete had a better warm-up.
  5. Almost all sporting events involve multiple contractions—they themselves should evoke PAP (and also fatigue), but these repetitive “conditioning” contractions are never considered. For example, coaches spend every effort to potentiate the performance with conditioning contractions like maximal countermovement jumps, med ball throws, etc. However, they ignore the fact that the first contraction of an event will also potentiate the subsequent contraction, the second will potentiate the third, and so on…
Coaches & sports scientists have long thought that PAP contributes to improved human performance, but it’s difficult to determine this specifically, says @jfletcher14. Share on X

This isn’t to say that these “conditioning contractions” often performed as part of an athlete’s warm-up can’t improve performance—clearly, there are many studies showing performance improves following this additional warm-up. However, it is difficult to determine specifically whether this improved performance is a result of PAP or something else.

Freelap USA: Swimming is seen as a sport from another world due to the properties of water. For coaches to take advantage of the medium, how should they treat pool training in their monitoring if they are a land-based team sport? It’s possible to get a high metabolic load with low eccentric stress, making it a tricky training session for some coaches who don’t know how to quantify the workout.

Dr. Jared Fletcher: When I first began working with swim teams and coaches as a graduate student, I was frankly (naively) amazed at the volumes these athletes could apparently handle. As a former middle-distance runner, I was amazed that a 400m freestyle swimmer could do so much more work than a 1500m runner, despite the duration of the events being similar.

My message to coaches is often a simple one: Find some method you are confident in to quantify athlete load and stick with it, says @jfletcher14. Share on X

Quantifying the workout/training week/month/year of any athlete is a contentious issue, both in the training literature and on social media, probably because it is so difficult to try to quantify “load” in any sport. We wonder whether intensity x duration is enough, how to define “intensity,” etc. All of these methods, from simple to extremely complex, have their pros and cons. Therefore, my message to coaches is often a simple one: Find some method you are confident in and stick with it. With regular monitoring of various physiological and performance measures, coaches and physiologists start to get a good sense of what is “too much” or “too little” (however that may be quantified).

Freelap USA: You have a lot of experience with shoes and athletes, and cycling seems to have more going on than people once believed. In the past, the focus was above the ankle, especially with quads and hip flexors; now, a lot of attention is how the foot works within the stroke. Can you share how this may matter for those involved in soccer who use bike routines to improve fitness or aerobic capacity?

Dr. Jared Fletcher: Thanks very much for that compliment, but I would consider myself very low on the footwear totem pole compared to many of my colleagues (within and outside of the footwear industry). That said, when I was a postdoc in Dr. Benno Nigg’s lab, we were tasked with quantifying the mechanical and physiological effects of different cycling shoes, and we eventually published.3

The key difference between the shoe conditions we tested was in the torsional (twisting) stiffness, such that one shoe type allowed slightly more “twisting” along the longitudinal axis of the shoe. This would be closely equivalent to allowing pedal “float” on a bike setup. The hypothesis was that allowing the ankle/shoe complex to move relative to the pedal would reduce knee moments, which would eventually reduce overuse injuries. We found some minor, subject-specific differences in knee moments, but no differences in gross efficiency, so we began to question what the real benefit of cycling shoes could be.

A follow-up study then used a third shoe condition (a lightweight running shoe) as an “extreme” torsional stiffness shoe, for which we also show no difference in gross efficiency and, again, some small subject-specific differences in knee and ankle joint moments. These results essentially confirm the results of Straw and Kram4, who also showed gross efficiency was no different between running and cycling shoes. We, and others, hypothesize that the benefits of cycling shoes may be seen over long-duration trials (perhaps several hours, as is seen in stage races) and/or during the sprint finish of stage races, but this remains to be tested.

If you use cycling shoes, you probably want to ensure your shoe/pedal interface has at least some float to reduce knee and/or ankle joint loads, says @jfletcher14. Share on X

So, for those athletes cycling as part of a cross-training program, my simple suggestion is that shoe-type probably doesn’t matter for most of us: we cycle at relatively low power outputs for relatively short periods of time. However, if you use cycling shoes (anecdotally, they “feel” better, I will admit), you probably want to ensure your shoe/pedal interface has at least some float to reduce knee and/or ankle joint loads.

Freelap USA: HR monitoring is useful but obviously limited. Can you share what is truly useful with heart rate? It seems some coaches have abandoned it, while others are overconfident with what they can do. Perhaps you could share some middle ground?

Dr. Jared Fletcher: The usefulness of HR is that it is a measure of exercise intensity: HR increases linearly with speed or power output. The issue with HR measurement is that HR takes some time to reach a steady state (2–3 minutes), so for intervals shorter than this, the measured HR will be lower than what the intensity would suggest. Further, above the anaerobic threshold, HR will not reach a steady state, and so the time at which HR is measured will affect the actual HR measurement. Lastly, over long-duration events, cardiovascular drift will also affect the interpretation of HR over time.

So, coaches need to account for all of these factors (and others, like caffeine use, over/under training, previous exercise, etc.) to properly interpret HR measurements during a workout session. Is it useful to monitor the intensity of an easy off-day run or swim to ensure the athlete isn’t going too hard? Probably. Is it beneficial to try to measure HR at the end of a 100m freestyle swim to determine if the athlete “gave it their all”? Probably not. We coaches and sport scientists need to manage the on and off kinetics of HR to properly interpret what the HR measurement actually implies.

Freelap USA: Isometric strength and Achilles tendon development is a hot topic. How should we look at the role and function of the Achilles and how do we prepare it for sport? Coaches are confused about how elastic energy is utilized, and a lot of return to play strategies are failing now. Is there something most coaches are missing?

Dr. Jared Fletcher: Of course, I’m biased, but what an exciting time to be conducting Achilles tendon research! Back in the early 2000s, several studies from Kubo et al.5–8 showed that isometric strength training increased Achilles tendon stiffness (how much force is required to stretch it).

One of my first graduate studies9 attempted to replicate these studies in a group of well-trained distance runners and then examine the impact of this training on changes in Achilles tendon stiffness and running economy. The idea was based on a previous study by Arampatzis et al.10, which showed that runners with good running economy (a low-energy cost to run a given distance) had a higher Achilles tendon stiffness. So, using a crossover, randomized design, we tested the hypothesis that running economy would improve following a period of isometric strength training of the ankle plantar flexors as a result of increases in Achilles tendon stiffness compared to another group of similarly trained runners who did not perform the isometric training.

While we found a relationship between how much the Achilles tendon stiffness increased/decreased and how much the energy cost decreased/increased, a larger question arose: How or why do increases in Achilles tendon stiffness result in a lower energy cost of running? Since then, we (and many, many others) have performed a range of studies, trying to examine how the muscle and tendon interact during various forms of exercise.

In short, our lower limbs consist of various muscle-tendon units and having a tendon that can stretch and recoil at various lengths and velocities allows the muscle length changes and velocities to remain low. If our lower limbs did not have tendons, this length change would have to be accomplished by the muscle itself and this lengthening/shortening costs energy and/or reduces the force or power capability of the muscle. So, tendons serve to reduce the energy cost of muscle contraction during long-duration events and may also act as power amplifiers during short-duration events (because the tendon can stretch and recoil faster than the muscle can).

Tendons serve to reduce the energy cost of muscle contraction during long-duration events and may also act as power amplifiers during short-duration events, says @jfletcher14. Share on X

When a tendon is stretched, it stores elastic strain energy, which can subsequently be released during shortening. This strain energy contributes to the mechanical work that the muscle would otherwise have to do. It is often thought that this strain energy contributes quite a substantial portion of the total energy required to run. We11 recently proposed the idea that this elastic strain energy does not come with zero metabolic cost, so we calculated the cost of storing/releasing this strain energy of the Achilles during running at various speeds and in different levels of runners (trained males and females, and some well-trained male runners). We proposed that the metabolic energy required to store and release energy from the tendon is quite high; even greater than the strain energy returned from the tendon.

From these data, we proposed a bit of a paradigm shift: Runners are able to run economically, not necessarily because their tendons store and return large amounts of strain energy, but because these economical runners’ tendons allow the muscles to operate at favorable lengths and velocities to keep their metabolic costs low. The idea that different runners have an “optimal tendon stiffness” has been proposed in the literature, depending on whether the tendon helps to reduce metabolic cost (like in distance running) or allow the whole muscle-tendon unit to lengthen and shorten faster to amplify power (like in sprinting).

In terms of return to play strategies, coaches and athletes should be aware: 1) of the basic physiology and mechanics of what the tendon might be doing during the activity, and 2) that the tendon is sufficiently strong to handle the stretch-shortening imposed on it during the activity. Certainly, there is some great work out of Dr. Keith Baar’s lab (and some excellent podcasts recently) showing various exercise (i.e., skipping rope) and nutritional (consuming gelatin) interventions to increase collagen synthesis and improve tendon health.12

15 Things to Remember If You Love Your Child-Athlete

Blog| ByJeremy Frisch

Frisch Youth Training

Countless parents want to know how to be properly supportive of their children who participate in sports. Usually, most fathers and mothers have good intentions, but when it comes down to it, the biggest problem with youth sports is the parents themselves. The good news is that most of the current challenges in youth sports can be solved with education and awareness. So, if you care about enriching an athlete’s childhood, make sure you consider the following points. Of course, there are things to consider beyond this list, but if you tackle even just a handful of the recommendations, your child will be better off in the long run.

Most fathers and mothers have good intentions, but when it comes down to it, the biggest problem with youth sports is the parents themselves, says @JeremyFrisch. Share on X

I am a father of four kids and own a training facility, so I understand both the business and personal sides of the sports equation. We all want our kids to be the best they can be, but if we push our kids too hard, they will likely end up having a bad experience. Much of what I recommend isn’t intuitive at first glance, but if you stop and think about what’s best for kids in the long run, you will likely agree with me. Here are 15 helpful hints and recommendations that will make a difference in your child’s growth in sports.

1. Don’t Join Travel Teams Too Early

Nearly every athlete who joins a travel team pays an unnecessary cost to play sports. Playing sports should be a right, not a privilege. Just playing sports locally has a cost, and it is simply not necessary to add travel to the equation. Most of the travel teams in youth sports are money-making businesses that actually do more harm than good. Kids don’t need to fly to the other side of the country to find the right competition, especially when an older sibling or neighbor can usually hand a convincing loss to your son or daughter.

Besides the cost of travel and club fees, the amount of competition in tournaments is too much for a young body to handle. When a kid plays the same sport year-round, burnout is likely to occur, and by the time they reach high school, the probability of your son or daughter wanting to play in college isn’t high. Save your money and let them enjoy their recreation or town league, as it gives them the opportunity to have fun and grow into the game without the pressure to win.

As your child grows, choose an organization committed to player development. That means fewer competitions and more focus on practice opportunities, says @JeremyFrisch. Share on X

As a child grows and enters high school, traveling a few times a year may make sense, but be sure to do your homework to choose the right organization. Look for an organization committed to player development. That means fewer competitions and more focus on practice opportunities. Playing for a team that competes as much as possible just for exposure is often a road to burnout and injury. Even if a young athlete is truly national-level athlete material, competing all the time isn’t necessary to become an elite athlete, as college athletics has plenty of opportunities to improve. If you want your son or daughter to make a college coach excited, be sure you tell them they play multiple sports because you are giving them a wide array of movements and experiences to learn from.

2. Teach Your Kid How to Swim

You don’t need to turn your son or daughter into the next Michael Phelps or Katie Ledecky, but you need to make sure they are aware of the risks and requirements when it comes to enjoying the water. Whether it’s a small pool or an ocean, the inability to swim can lead to a life-or-death scenario. Learning to swim is a life skill that is just as important as learning to read and write.

As kids grow up and gain their independence, the parent may not always be around. It’s good peace of mind for parents when their son or daughter knows how to swim, especially if a water situation should arise. Kids who are competent in the water are safer when participating in outdoor activities such as boating and going to water parks. For those parents who want professional coaching, this is one of the few times when getting a qualified instructor early makes sense and is recommended.

Don’t expect your school to provide swimming instruction anymore. In the past, colleges required students to pass a swimming test in order to graduate! Now, swimming is seen as optional, and, like reading, there are an unfortunate number of kids growing up not knowing how to swim. Even if your child doesn’t enjoy or excel at swimming, it’s one of the few activities you need to put your foot down on and require. Kids are often reflections of their parents, so if you don’t swim or don’t know how to swim, it’s likely they won’t either, unless you intervene with lessons.

No matter their interests in other sports, kids need to learn how to swim. Who knows—if they love it, they may grow up to be the next Olympic champion, but start with safety first.

3. Play Games Year-Round, Not Sports

Most sports are demanding on adult bodies, so you need to evaluate the assumption that playing sports is good exercise for kids. Games and activities that are sport-like but usually less competitive in nature are important for exposing kids to a wide variety of athletic challenges. For instance, pickleball is great because it’s quick to learn and encourages more kids to get involved. Throw a frisbee around or play simple games such as tag or pick-up versions of sports rather than “over-organized” sports.

Kids should enjoy the play part of sports, not need to be the next Tom Brady or Serena Williams. Game play focuses on the experience of the moment, not trying to win or make a squad. Kids don’t have to win or lose to be productive, so instead of giving everyone a trophy for participation, just eliminate the score and focus on the fun. There are many games and activities that are not about winning or keeping score, such as playing catch or shooting hoops, so don’t worry about your son or daughter getting enough structured sports.

Sometimes, too much coaching leaves kids robotic and less instinctual, rendering your child less athletic. As kids mature and head toward middle school, games can become actual sports games, but limit their competition so they are not doing too much. Playing six games over a two-day tournament every single weekend is too much on developing bodies. Tournaments are fine if the games are abbreviated and modified, but most of the time, playing too many competitive games for hours leaves kids exhausted and flat.

4. Stop with Youth Conditioning Programs, Please

As kids mature and become adults, the need for formalized strength and conditioning programs increases. But having a child replicate the same training as a college football strength and conditioning session misses out on athletic development. There’s nothing wrong with medicine balls and barbells, or even bodyweight training, but we need more physical education dealing with how to move. An athlete who is 8 or 9 shouldn’t necessarily be exercising; they should be playing and learning.

For example, activities like an obstacle course allow kids to self-challenge and explore movement. Using watered-down strength and conditioning programs in middle school undermines the opportunity for kids to learn to run, jump, and throw properly. Conditioning and barbells are not dangerous—they just enhance athleticism; they do not create better movers. A combination of teaching and training is best for youth athletes and doing only one or the other leaves kids with large gaps in physical literacy.

5. Be a Good Sports Fan

One of the most overlooked problems of sports is not the athletes, but the fans. As parents, we are role models for our children, and we should treat a sporting event like a positive experience. It’s okay to “boo” bad sportsmanship or dirty play, but don’t heckle athletes who are not performing well if they are trying. A modern sporting event might not be a cheap experience for a family after you pay for tickets, concessions, and parking, but that doesn’t give us the right to be a bad fan in the stands.

Showing a positive and composed demeanor to your son or daughter teaches them to become good fans and, hopefully, good teammates. Often, a child-athlete will not be a starter, so they will need to be a good teammate to their peers when they are on the bench. If you are a good fan to begin with, you will be a better teammate when you are an athlete competing. It is essential to learn to respect officials and referees from a young age, and bringing a healthy fan experience to youth sports is even more important. It’s disgusting to see parents fighting and being mean to children, and to stop it, we need to start teaching the next generation to become good fans in sports.

6. Don’t Forget to Play with the Dog

Something as simple as playing with the family dog will not result in medals, but it will be a rewarding experience for everyone involved. When your son or daughter plays with your dog outside, it not only helps your pet, it may even result in your child becoming a better athlete! Dogs are fast, agile, and bundles of energy. Going outside and chasing and fleeing from a dog is fun and challenging for young kids.

One of the biggest gifts in life is spending time with someone, and kids today are playing less in general and likely leaving “man’s best friend” out of the picture. In fact, a 2018 study by the Association for Pet Obesity Prevention found that 56% of dogs were overweight or obese. It’s not surprising that with less-active children come less-active dogs.

You can play catch or keep away with a dog—it doesn’t matter what. Just playing with a dog is a great way to teach kids responsibility for someone else. If a child-athlete understands the need to keep another living being healthy, they will likely respect their own need for exercise in the future.

7. Host a Wiffle Ball Tournament

A surprising idea that I stumbled upon a while ago is the idea of having kids create a playoff system for a game that is timeless but dying off. Wiffle ball is fun and easy to play and requires very little officiating to run. The reason we like tournaments with Wiffle ball is that it gives an opportunity for the kids to organize the game, such as deciding on home run distances, policing outs when plays are close, and removing parents from stands.

You don’t need to attend a sports camp to be a better athlete—you have plenty of options for development in your own town, says @JeremyFrisch. Share on X

It balances Little League games and, while a tournament may sound competitive, it’s more about everyone playing each other than finding out who the best team is. You don’t need to create winners’ and losers’ brackets; just make it a round robin format so everyone can play each other. You can make it coed and mixed age groups, as long as it’s balanced so the tournament is a healthy competition, meaning it is not too one-sided. You don’t need to attend a sports camp to be a better athlete; you have plenty of options for development in your own town.

8. Learn Gymnastics Fundamentals

The heart and soul of most gymnastics activities is body manipulation, not a ball or implement. The best way to learn to become more athletic is by learning fundamental gymnastics actions, and not competing is perfectly fine. Before we start scoring the proficiency and style of a movement, we need to make sure kids are safely able to do core movements in gymnastics.

Years ago, we saw the term “tumbling” used interchangeably for gymnastics, and while it was wrong, the intent was right on. Gymnastics develops plenty of upper and lower body strength, and as the athlete ages and grows, the demands of the exercises increase as well. You don’t need to do a floor routine to get value from gymnastics; you can simply learn to climb a rope and balance dynamically without fear of injury.

If you are a parent looking for physical activities for your young child, enroll them in a basic gymnastics program before getting involved in t-ball or flag football, says @JeremyFrisch. Share on X

Kids need gymnastics more than ever, as they are moving on to specialized sports too early. Gymnastics, like dance, is for both boys and girls, and teaching them to value coordination and speed at an early age is a great head start for becoming a better athlete. If you are a parent looking for physical activities for your young child, I would recommend enrolling them in a basic gymnastics program before getting involved in t-ball or flag football. The development of all-around strength and coordination will go a long way in helping develop skills in traditional competitive sports later on.

9. Reinforce Unstructured Play

You can play a sport, play a game, or just play. Parents need to let kids just enjoy being kids, not worry that they are not adding the right ingredients to become a better athlete. A happy kid has the best chance at becoming a great athlete, so let your kids do activities that are just fun without any structure at all. Games are part of the formula, but you don’t even have to play a game at all to be a successful athlete down the road.

Games have rules or structure, while sports have rules and an end where half the participants or more are losers. Free play is just enjoying the moment, like jumping on a trampoline or jumping off a swing. Riding bikes was always a favorite of mine. It was especially fun to ride on local trails through the woods. Riding up and over small hills, over rocks, and through streams was always enjoyable and messy, and I developed a good bit of coordinated riding ability.

You don’t need to follow a strict set of rules or guidelines, and that fosters creativity and exploration. Plenty of options that have some structure like foursquare and hopscotch exist, but they have very minimal rules and kids don’t need a coach to play. Unstructured play removes the adult from the equation, and that is the best gift you can give a child, as it encourages them to learn to teach themselves.

10. Make Dodgeball for Everyone

Dodgeball isn’t the problem with physical education; it’s likely the way we treat each other that is the culprit behind a bad dodgeball experience. When those outside the trenches weigh in on experiences they don’t know firsthand, we see a distorted reality that isn’t a true depiction of the problem. Dodgeball should not be seen as anything outside of a sport, as it’s not dangerous and not unhealthy to a child’s psyche.

Imagine being the kid who strikes out and lets a team down in a Little League title game compared to a gym class that plays for time rather than a score. The game of dodgeball isn’t about picking on the weak; it’s about learning to find ways to contribute and be crafty. The game is very self-limiting with risk, so if you are not as athletic, you can play defensively.

Some versions of dodgeball include alternatives rules where each player can contribute in different ways outside of throwing, dodging, and catching. One great way to play is, instead of a player being eliminated from the game, you add a movement exercise and then they rejoin the game. This version is great as the game almost never ends, and kids get plenty of movement and exercise. Kids will always have to deal with activities that they are not the best at, so blaming dodgeball for hurting a child’s morale is just as foolish as banning spelling bees or science fairs.

11. Demand Physical Education for Movement Literary

Physical education is one of the first classes cut or eliminated by schools, and that is a major mistake for both sport and academic achievement. Along with recess, having constant exposure to movement is one of the best ways to help kids focus and learn their subjects in school. Instead of complaining or discussing why other countries like Norway or Finland are better models than the U.S., make sure you organize locally by attending school committee meetings. Don’t settle for answers that sound more like convenient excuses—fight for the health and well-being of the students.

Schools are under pressure for testing performance, so change will be a prolonged battle. Small wins, such as another recess period in the morning or another half hour during the week, will add up in the long run. Keep in mind that you are fighting for real physical education, activities that teach skills, not wellness for children. With childhood obesity so prevalent, many schools resort to fitness classes that are not engaging or effective for actual weight management. Kids should be playing games and learning activities all the way into high school. Some high schools have adopted the weight training class to pay for strength and conditioning coaches, but we need to remember that specialization is already extreme at that point, and small exposures to different sports and activities may improve an athlete as well.

12. Roughhouse and Wrestle with Both Sons and Daughters

It’s sad that the sport of wrestling is at risk of being left out of the Olympics, and the only way to save it is to support it. Wrestling is not just for boys anymore, and all athletes, not just male ones, should learn how to wrestle. The popularity of MMA and other combat sports is a great sign for the future of the sport, but for kids, it’s okay to wrestle and embrace the chaos of one of the world’s oldest sports.

Wrestling is not about violence and doesn’t create aggressive children. In fact, it allows them to be expressive and improves their connections to their parents or siblings. Roughhousing, provided it’s safe, is normal and expected for children. Even toddlers love the exhilaration of the twisting, turning, and flipping of rough-and-tumble play with a parent. Not only are rough-and-tumble activities fun, but they are a fantastic avenue to develop the all-important vestibular apparatus of the inner ear, which is involved in balance, coordination, and emotion.

These days, more and more kids struggle to control their emotions and temper, and it may be because they have very little experience to know what is right and what is wrong with rough play. There are several articles available online that are supported by enough psychologists to justify that you are likely just fine roughhousing with your kids. Read this article on play-fighting for yourself and be your own judge.

13. Hire Private Coaches Sparingly

When kids are not excelling early, there is a temptation to do more work or tutoring. There are plenty of benefits to working with a coach, including building self-esteem, but when a child-athlete equates all of their value with sport, it becomes unhealthy. Kids don’t need to be great at sports right away, they just need to have fun playing them. Parents need to realize that kids will get better with enough time and practice.

Obviously, it doesn’t feel great socially to not excel, but provided they feel included and are not viewed as a liability for team play, not being a starter has value in the long run. Kids must learn to problem-solve without the help of an adult. Bailing kids out of athletic ineptitude won’t help them when they are on their own, so don’t hire a private coach unless a child wants to be better. I have found that when the young athlete asks for help, and not the parent, it is a good time to look for an outside coaching source because the kid truly wants to get better rather than it just being the parents’ dream.

Kids don’t always learn to be good teammates when winning is rewarded and learning is a means to an end. Kids who work with private coaches tend to forget the value of practicing with their team coach, and it becomes a political nightmare when too many cooks are in the kitchen. Add in an overzealous parent, and soon the process is too crowded with opinions.

Private coaches are not the problem. At times, they are a part of the solution. But hiring them for the wrong reasons and wrong time is not a good idea. Parents, coaches, and the youth athlete should be involved with the discussion on private coaching, and when the group thinks it’s a good idea, then proceeding with tutoring or coaching makes sense.

14. Let Your Kids Officiate or Play Alone

While I encourage families to be together for dinner, having parents chaperone every sporting event or practice is a bad idea. Kids need some free time away from mom and dad. Helicopter parenting has actually decreased a child’s ability to think and reason since thinking and reasoning are done for them, and playing with others is a social skill, not just a physical endeavor. More and more kids need to play sports and control their environment by learning to compromise, negotiate, and be diplomatic. Organized sports are too organized, forcing kids into rules and a structure that are more about what the parents want and not what the kids need. Allowing kids to create their own rules and/or change the activity to what they perceive is fun will tailor sports to their enjoyment.

Organized sports are too organized, forcing kids into rules and a structure that are more about what the parents want and not what the kids need, says @JeremyFrisch. Share on X

One way to do this is to make a sports bag for the kids, and fill it with Wiffle balls, bats, kickballs, tennis balls, frisbees, etc. Give the kids the bag, some space, and free time, and then get the heck out of the way. Parents forget that kids just want time away and/or freedom, as they are too often controlled by adults. Not having fans or parents watching allows kids to experiment, take risks, and express themselves through sport in different ways than during the constraints of organized sports.

The optimal balance between structure and open free play is unknown, but when sports are too formal, the fun starts to wane and the drop-off rate increases. Kids need just enough structure to be on the right path, but parents should not be the trailblazers, the youth athlete needs to be.

15. Practice, Practice, Practice

Sometimes repetition is necessary to learn a skill or sport, so don’t just hope that everything will fall into place. Batting practice in baseball is a great example of why a kid may literally take 4–5 swings in a game and technically fail to reach first base even if they make contact. Spending time in the backyard or with a bunch of other kids is not expensive, and they should only seek out hitting instructors as needed. It’s pointless to spend time and money on technique if the coach doesn’t have much to work with.

Parents should be involved at early levels but, as the child matures, leave the growth and improvement to qualified coaches. You don’t need to have a child spend countless hours with mind-numbing drills, but if a kid likes to shoot around for hours, let them. Usually, children self-regulate when they are tired or bored, so trust that they will decide how much is enough.

If a child-athlete wants to be better, you will know it: They will talk often about how much they love the sport, and they will put in the effort to get better. This is how you will know they are enjoying the journey. Kids who are stagnating because they don’t know how to properly execute a task need a hint or two, not full immersion in a coaching program or extra lessons. It’s okay to struggle, provided it’s productive, and that means experimenting, not just expecting different results by doing the same thing over and over. 

A Smile Is the Best Sign of Athletic Development

Remember: A happy athlete is one who will more than likely improve, so don’t lose sight of the fact that sports at early ages are not meant to be professional or elite. Even young talents need to enjoy their childhood and just be kids. What we are seeing is a growing trend, especially with more affluent families, to chase excellence with resources instead of being patient and trusting a process that leaves us feeling less in control. Sports are a gift, and we need to embrace the fact that talent and time tend to be more influential than investing in coaching and training. Of course, proper instruction and having good coaches matter, but athleticism is more about genetics and environment than any other combination.

Support your children by adding an enriching experience of as many activities as possible, and only start specializing as they get closer to adulthood. The truth is that most of the successful athletes in college are multi-sport athletes because they were talented and didn’t burn out. Forcing a kid to specialize in the hopes they will get a scholarship or be accepted by a better school is a lousy plan, and it usually leads to injury and/or disappointment.

Campus Sports Complex

How Setting Department Procedures and Policies Can Improve Athlete Safety

Blog| ByGeorge Greene

Campus Sports Complex

Collectively, strength and conditioning professionals need to help raise the standards of the profession, and one important way to achieve this is by setting institutionalized procedures and best practices. The CSCCa and NSCA Joint Consensus Guidelines for Transition Periods is a positive step in the right direction and provides a valuable resource for coaches to use when onboarding student-athletes.

When an athlete steps off-campus for summer or winter break—or is a new athlete entering your program—their true training history is unknown. Maybe they worked out at their high school or a local private facility, but unless you are in constant communication with these athletes, there’s a good chance you’re in the dark. Did they follow a progressive resistance training program? Were they on a running program that established a foundation for summer conditioning equivalent to the athletes currently on campus?

For the most part, the answers most likely are no—therefore, it’s your responsibly as a coach to meet them where they are currently. It’s also critical to establish open lines of communication with other key support staff members who impact the student-athletes.

This article will cover two key topics:

  1. How we onboard incoming freshmen and transfers, outlining the standard procedures that help us run our program effectively.
  2. How we communicate and collaborate with sports medicine and use other operating procedures to serve our student-athletes best.

Having a plan and a process allows you to have professional guardrails in place to improve outcomes and athlete safety.

Challenges with Incoming Freshmen and Transfers

Most coaches I’ve talked to around the country have the same struggles when trying to onboard new athletes into their program. Although every university has its own unique set of challenges, here is a list of some of the issues most commonly faced.

Unknown training history. Athletes report to campus from all over the world, and their training history and background can vary significantly. I’ve had freshmen come from places like Cressey Sports Performance with great training backgrounds and others who have never set foot in a weight room before entering ours.

Short acclimation period (fall teams). Many of our fall sport teams have 10-14 days of practice before their first official game, offering little to no time to train optimally. And freshmen and transfers often compete for playing time immediately.

Structural imbalances. With athletes specializing earlier, we see many athletes come in with imbalances and movement deficiencies. For example, a basketball player might arrive on campus with a 40-inch vertical but still can’t do a lunge without losing balance.

Integrating freshmen and transfers with the returners. It is easier said than done to have multiple programs going on at one time in your facility—especially if you’re running the sessions single-handedly.

Steps to Address These Challenges

Step 1. Put all new athletes on the Block Zero program. More on this below.

Step 2. Juice up your internship program. Tap into your campus resources and local exercise science departments to improve your internship program. With multiple programs going on in one session, you need more eyes on the floor. On campus, we use the physical therapy, health science, and nutrition departments for volunteers, interns, and work-study students. Our internship coordinator also has established relationships with several local universities that send us full-time semester interns. As our internship program has grown, we’ve had several certified post-graduate interns looking to gain experience, as well. This takes some work on the front end, but in the long run, it can really help you grow your department.

Step 3. Institute an “all hands on deck” approach when necessary. If you don’t have enough help, use full-time staff who work with other teams during the onboarding phase. It’s never a bad thing to have other coaches from your staff get to know other student-athletes.

Step 4. Use overtime cards. Once athlete deficiencies are recognized, we prescribe the athletes individualized corrective exercises or short workouts to do with the training program either before or after workouts (or on a separate day). This allows us to individualize training and give athletes extra work based on their needs. For example, if an athlete is struggling from a conditioning standpoint, they might do bike intervals while an athlete with poor core strength does extra suitcase carries, planks, and Pallof presses.

Overtime Cards
Image 1. Overtime cards provide extra individualized workouts or correctives for incoming athletes to work on their deficiencies.

Establishing a Block Zero Program

We took this concept from Coach Joe Kenn, Head Strength and Conditioning Coach of the Carolina Panthers. Regardless of the sport, we have every new athlete complete our Block Zero program. Athletes must pass competency in each of our main movements before progressing to more advanced movements. We’ve had this system in place as a department for the past three years, and it has allowed us to:

  1. Teach and enforce proper movement from Day 1
  2. Safely progress athletes with varying training histories
  3. Separate the incoming players from the returners so we can have more eyes on them during a critical period
  4. Create good training habits and break bad ones

Incoming freshmen who play a spring sport are split from the returners during the session and have a completely different program. For those who compete right away in a fall sport, we use the Block Zero exercises to replace our more advanced exercises used by the returners. For example, if our upperclassmen are front squatting, the freshmen will do landmine or goblet squats. If our upperclassmen are barbell benching, our freshmen are doing tempo push-ups or DB bench press. This lets us keep everyone together to account for the demands of the hectic in-season schedule.

A question I often get from other strength coaches is, “Do your sport coaches have any issues with this?” In three years, we haven’t had one coach question this program. If anything, they appreciate that their athletes will be taught how to do everything the right way while we continue advancing and pushing the returning players.

Below is the bank of exercises our coaches can choose from when designing their Block Zero program. If you have more advanced freshmen or transfers, you can continue to challenge them within these parameters. For example, you can add tempos to a landmine squat or a vest to the single-leg squat.

  • Squat Pattern: Banded BW Squat, Goblet Squat, Landmine Squat
  • Hinge Pattern: Dowel Hinge, Band Good Morning, DB RDL, Band Pull Through
  • Single Leg: BW SL Squat (off a short box), BW or DB Split Squat
  • Press Pattern: DB Bench Press, Tempo Push-Ups, Seated DB Shoulder Press
  • Pull Pattern: Chest Supported Row, Lat Pull Down, Cable Rows
  • Core: Suitcase Carries, Pallof Press (and variations), Dead Bugs, Farmers Walks, Plank Variations

Below is a sample of one of our original programs. We paired each exercise with a corrective to help improve the quality of the movement, and each week the athletes progress in either load or volume.

Block Zero Sample Lifts

Table 1. A sample of one of our original programs. We paired each exercise with a corrective to help improve the movement’s quality. Athletes progress in either load or volume each week.


In addition to our weight room progressions, we have speed and plyo progressions. You can see an example 8-week outline below. We used Complete Jump Training by Adam Feit and Bobby Smith as a resource to develop this program. While many of our athletes come in with great athleticism and impressive vertical jumps, most of them struggle with the ability to land correctly. This program has been extremely helpful for us to coach and progress jumps and movement in the same capacity we do our compound lifts.

Stony Brook Plyo

Lastly, below is an outline of our 5-week conditioning progression for incoming freshmen and the acclimation periods. The set work/rest ratios allow each coach the flexibility to use different methods while sticking with parameters that safely progress the athlete. We designed this program based on the guidelines set by the CSCCa and the NSCA. We implemented this protocol over the previous summer and found it provides the right ratio for groups of athletes who have varying training histories.

For example, we had one group of incoming players that included a junior college transfer, a true freshman, and a true freshman coming off a minor injury. The program was relatively easy for the junior college transfer, challenging for the true freshmen, and hard but appropriate for the freshman coming off an injury.

Block Zero Plyos

Results of Our Block Zero Program

Reduced injuries. Since implementing these programs across the board, we’ve seen a significant decrease in injuries with incoming freshmen, both in the weight room and on the playing field or court.

Improved performance. The before and after photo below is the 9-month transformation of a former student-athlete. He was a junior college transfer who had done no formal training before stepping on campus—and at 6’7 with a 7’0 wingspan, weight training didn’t come naturally for him. In his first year, he was a starter right away for us, and we did not deviate far from the sample weightlifting program shown above. Combined with improving his diet and consistently working hard every single day, he put on 28 lbs and increased his vertical by 3.5 inches during a season in which he started all 33 games.

Our first-year men’s basketball players average a 10-pound gain in body weight & a 4-inch vertical jump increase, says @GreeneStrength. Share on X

With our men’s basketball program, we’ve seen an average body weight increase of 10lbs and a vertical jump increase of 4 inches for first-year players in our program. In short, it doesn’t take an advanced program for someone new to training to make extraordinary progress.

Increased buy-in from coaches and sports medicine. Since there is a clear understanding of what a large population of student-athletes will do when they first start in the weight room, our coaches, sports medicine staff, and athletic performance staff are all on the same page, which leads directly into my next topic.

Common Communication Challenges with Sports Medicine

Our communication and collaboration with sports medicine are critical for the development and health and safety of our student-athletes. These two groups need to work closer than any other support units in the department. Both strength and conditioning coaches and athletic trainers spend a great deal of time with the student-athletes and can make a tremendous impact when they’re on the same page.

Ego. One of the most common issues with strength and conditioning coaches and athletic trainers around the country is ego. In most cases, one person believes their job is being done by the other. Another contributor is the lack of understanding of each role.

Return to play programs. If there is no structured process for return to play protocols as athletes transition back into the weight room, you’re doing your athletes a disservice and setting yourself up for conflict between the two parties. All athletes need to be treated as individuals when they are coming back from injury. And protocols that we’ve discussed, reviewed, and agreed upon give everyone involved peace of mind. Why would the athletic trainer want to turn the athlete over to strength and conditioning staff if there isn’t a plan in place? Adjustments can be made as you go, but have a structured program in place.

Poor communication. A lot of issues that arise across the board in any field come down to poor communication. A poorly worded email or text, forgetting to send a response to a message, or leaving someone out of a discussion can cause problems even when it wasn’t intentional.

Lack of collaboration. The reality is both fields have a lot of crossovers, especially regarding areas like flexibility, recovery, and nutrition. Naturally, people tend to grab hold of things instead of using each other as a resource. And for those strength and conditioning coaches and athletic trainers responsible for multiple sports, the communication might be limited to just an email or two per week or catching up in the hallway if they ran into each other, which causes miscommunication.

Athletic trainers and S&C coaches who travel and attend practice together have better relationships, trust, & collaboration, says @GreeneStrength. Share on X

We found that teams that have an athletic trainer and a strength and conditioning coach who traveled and attended practice together always had better relationships, trust, and collaboration. This was due to the amount of time spent together during the year with road trips and long practices. The head athletic trainer and I worked together to put protocols in place that allowed staff members the opportunity to create relationships.

Steps to Address Communication Challenges

Meetings. Each ATR and S&C meet at least once per week (outside of practice) to discuss the athletes in general, what they see in the weight room, current training program, current rehab programs, etc. This not only keeps everyone on the same page when it comes to the athlete, but it also helps improve the relationship and trust between the two groups.

Aligned hours. We do not open for any weight training or conditioning sessions unless someone is present in the training room.

Return to play programs. All athletes returning from concussions or surgery of any kind have set protocols agreed upon by both the athletic performance staff and the athletic training staff. We also have a staff member who has a primary administrative assignment to oversee the programming and progression for each athlete coming back after surgery.

Individual screening process. Our athletic performance staff and athletic training staff work together to screen all incoming student-athletes and create protocols specific for each team. For example, our basketball program will do a series of jumps on the force plate, an overhead squat, and a single-leg squat test while our baseball program will go through a completely different assessment. This helps us identify structural imbalances and performance strengths and weaknesses and also pushes members of both staffs to work together and be on the same page.

Group staff meeting. Two years ago, we organized a meeting with both staffs and laid out an overview of communication expectations as well as any coordinated projects between the two groups to keep everyone on the same page. At the start of each academic year, we get together to lay out any new plans for staff members joining the department.

Results of Increased Communication

Improved working relationship. The scheduled meetings significantly increased the trust and respect between the two groups, and the miscommunications slowly disappeared with this collaborative approach.

Friendships. Many of the staff members have become friends outside of work. Friendships are not a necessity but have brought the two groups closer together which, in turn, has positively impacted the student-athletes.

Ego is left out of it. When you get to know someone, you usually understand their intentions better and don’t take things personally. The increased communication has allowed all parties to do what is best for the athletes, regardless of who comes up with the idea.

Positive crossover. Because of the nature of the strength and conditioning and athletic training professions, there will be some crossovers. Athletes might come into the weight room to roll and stretch, or they might go down to the training room. We use the overtime cards for athletes who have pre-existing injuries and need some extra work but not necessarily one on one treatment in the training room. These are two examples of how having everyone on the same page can save everyone time. It also allows athletes who might need specific individual attention with a trainer to get better while athletes who just need maintenance work can fit it into their routine.

Other Effective Operating Procedures

High-performance meetings. Last year, we began having high-performance meetings with several teams, which included the sport staff, strength and conditioning, athletic training, and academics. In-season teams would meet once a week, and off-season teams would meet bi-weekly. The meetings helped everyone stay on the same page regarding logistics like travel, schedule changes, or tough academic periods. It also helped keep everyone in tune with athletes having a tough time and managing the load of the athletes.

Athletic performance meetings and chalk talks. Every Friday, my staff and I get together and recap the week and discuss new training blocks for our teams. For example, if women’s soccer is about to start a new program, their coach will print copies of the plan and walk the entire staff through their thought process, bouncing ideas off everyone in the room. The process also lets us make sure we don’t have any holes in our programs and serves as a good opportunity for young coaches to practice describing their plan before they speak to the head coach.

Credentials. The fact that there are still people in collegiate strength and conditioning without earning certifications through the NSCA or CSCCa is scary. As a department leader, it’s your job to make sure that every member of your staff is certified and maintains their certification throughout their employment at your university. This is something every director should do at each institution to improve how we’re viewed as a profession.

Safety in numbers. Football obviously requires more attention than other sports in addition to larger teams like lacrosse and baseball. With these teams, we do everything in our power to get as many eyes in the room as possible. Sometimes that calls for all hands on deck or asking two coaches on staff to partner up on a team. Growing our internship program also has helped us with this.

Reporting lines. All athletic performance staff members report directly to me as the Associate AD for High Performance.

Pre-workout fueling. We do everything in our power to make sure the athletes have something in their bodies before each session. While educating them on the importance of eating before training is important, we go a step further to ensure they are prepared to work out. Snacks like bananas, chocolate milk, and granola bars are in our facility and available before any training session.

In-services. We aim for quarterly in-services or Skype sessions with programs and individuals around the country. One presentation that has benefited us from a health and safety perspective is from Josh Bullock, the Athletic Development Coach for US Ski and Snowboard. His topic was “Managing Common Health Conditions Encountered by the Exercise Professional,” which covered managing athletes with sickle cell, diabetes, spondylolisthesis, and asthma, among others.

Wrap Up

These protocols and policies have developed over time and continue to evolve each year. My staff and I at Stony Brook have chipped away at these to best serve our athletes during the last four years. Credit goes to my initial staff: Vincent Cagliostro, Director of Athletic Performance for Football at Stony Brook; GC Yerry, Assistant Strength and Conditioning Coach at Army West Point; and Patrick Cummings, Director of Football Performance at Buchholz High School for collaborating on the original protocols as well as my current staff—Kaitlyn Newell, Joe Quattrone, Joel Lynch, Kelly Cosgrove, and Rob Deese for bringing new ideas and updating these protocols each year.

The big takeaway from this article is for coaches, administrators, and high-performance professionals to look at their situation and address their unique problems in a systematic way—not necessarily to adopt these exact procedures.

New Head Coach

You Got a Head Coaching Job…Now What?

Blog| ByCarmen Pata



New Head Coach

By Carmen Pata

Here is what I see as a thoroughly confusing problem, not only in sports, but in the business world as well. We spend so much time and effort learning how to be really good at our job or profession, but nothing teaches us how to become a leader in those positions. Just think about it for a moment: If your education is similar to mine, then we both have a master’s degree in exercise and sport science on top of an undergraduate degree in a related field. Looking back at my curriculum in undergraduate and graduate school, I took classes on nutrition, anatomy, and physiology, coupled with all sorts of exercise testing, prescription, and theory.

Everything I had learned and accomplished prepared me to apply for a head coaching position but did nothing for me once I was hired as a head coach, says @CarmenPata. Share on X

Everything I had learned and accomplished prepared me to apply for a head coaching position—but the same education and experience that made me look like a good candidate on paper actually did nothing for me once I was hired as a head coach. Ironic? Yep. Here I am, finally the boss. I get to make all the decisions. I could do what I wanted to do, how I wanted to do it. And do you know what made the job even better? I had an assistant, which meant I had someone to whom I could assign all the work that I didn’t want to do. Happy days, right?

Well, no, not really.

Everything Works Until It Doesn’t

Despite my years of education and experience, nothing had prepared me to actually be in charge. And, at first, I was a really bad boss. I don’t know what happened, but being in that position of authority caused a brief bout of amnesia and I forgot all the lessons that I’d learned working in a woodworking factory in my hometown. Before I knew it, I was micromanaging, and being overbearing and untrusting on top of it.

This was a really easy trap to fall into simply because I was a more accomplished coach than the other staff members. I knew more about physiology. I knew more about psychology. I knew more about the training theories we used. And, I was better at getting the athletes to do what was programmed. My thought process centered around the belief that if my staff couldn’t get it done right or perform the task at my level, then I’d have to do it myself.

Now, being a better coach than the rest of your staff doesn’t necessarily mean that you are prepared to be in charge. Think about that for a second. I received a promotion because I was good at my job, but my story isn’t unique. When we all start out in our professions, we spend our education learning how to do our job to the best of our natural ability—but we never learn what to do once we’re promoted to those higher levels. Consequently, once that advancement is offered, we keep doing the exact same things that helped us get the promotion in the first place—working hands-on (micromanaging), doing everything ourselves (overbearing), and checking in with our staff much too often (untrusting).

Being a better coach than the rest of your staff doesn’t necessarily mean that you are prepared to be in charge. Think about that for a second, says @CarmenPata. Share on X

Here are three things I wish someone had told me when I first received that promotion, but I had to learn the hard way. Each of these three tips has helped me become a better head coach.

One

Become Really, Really Good at Asking for Help

Early on in my head coaching tenure, I really didn’t have any idea what I was doing. All of a sudden, I had to do budgets, risk assessments, staff evaluations, and more previously unknown things than I can even remember. All the feelings I had about this uncharted administrative world didn’t matter—the fact is, I needed to do these unknown tasks because they were now part of my job. So, I struggled with my newfound duties and responsibilities, which I’d never learned about during my education or in any of my prior roles.

Professionally speaking, this was a dark time for me. I was finally in the position that I wanted—I was the boss—but I was suffering from the negative stress and found myself wishing I could return to being an assistant again. Email after email landed in my inbox telling me I wasn’t following the minutiae of policies and procedures we were supposed to know about, even though no one ever told me or directed me where I could learn about these requirements. It didn’t matter: I was in the position for all of four days before I received a nasty email scolding me about a procedure I hadn’t followed.

Looking back on that situation, it was not like I was exposing athletes to immediate and life-threatening danger. I hadn’t accidently sent out a list of login credentials and passwords. I hadn’t carelessly downloaded a malicious computer virus. The issue was that I’d neglected to tell a vendor that we are a tax-exempt institution and was therefore charged $0.87 in tax on a purchase. That one error started a chain reaction of eight emails, two phone calls, and an eight-minute in-person scolding. If paying $0.87 in taxes caused that sort of reaction, what would happen if I made a real mistake with actual consequences?

It wasn’t until I was getting berated by our athletic director about making this mistake that I realized I had no clue how to do the job I’d been hired for. Even worse, while I didn’t have an understanding of how to do this job, I also didn’t feel like I could talk to the AD about it. Now that I was on everyone’s radar, it felt like instead of receiving support to pursue the things that I excelled in, people were trying to catch me messing up so they could remind me about each thing I’d done wrong.

What I’m going to say next is very embarrassing, but for a while all I did was just enough to get by. I wasn’t taking any risks. I wasn’t experimenting. I wasn’t trying to grow and improve myself or my staff. I wasn’t doing any of that; I was just trying to do my day-to-day tasks without drawing any extra attention to myself. All of this is the exact opposite of how I have tried to live my personal and professional lives. By acting this way, I felt that I was becoming a diminished version of myself—and, more importantly, that I wasn’t fit for the position I held.

Finally, I was fortunate to have a conversation that changed everything.

Just like it happens day-in and day-out in every gym, someone needed a spotter. Although I was working in my office and there were plenty of other capable people on the floor lifting, there was a knock at my door and a man I’d never met asked me for a spot while he was benching. Maybe he came to me simply because we were the only two people in the gym who were clearly not college-aged lifters. After his reps, we began the typical small talk that happens after you have just trusted a complete stranger to save your life if the lift goes wrong. It turned out that the man I spotted was the new commander of the Reserve Officers’ Training Corp (ROTC) on campus. As he reminded me, the ROTC program is there to prepare people to enter the United States military as officers.

Among the first topics in our unfolding conversation was what the cadets would do for training. We talked about the typical style of physical training (PT) and the obstacle course, but what stood out to me was the confidence course. Unlike the obstacle course, which is timed, with students scored on their performance, the confidence course is never timed and most of the challenges are very difficult to complete by yourself. Instead, the cadets learn that in order to pass and score well in the confidence course, they have to help each other.

Interestingly, the commander said that those cadets who are exceptionally strong, fit, or athletic, and who can complete the course by themselves, slowly find themselves ostracized by the rest of the group. That is, until they start helping others complete the course.

Reflecting on this, I wondered if I was in a similar situation. Here I am, strong and proud, doing everything on my own and struggling with it all. So, I did a little experiment—I offered my help. Starting small, I talked to our coaches. I asked them what problems they were having and tried to help them fix these issues. In the course of helping the coaches solve their problems, we talked about the administrative issues I was having. Guess what? While helping our coaches find solutions to their problems, I was getting solutions to my problems. It took some time, but after a while I wasn’t on the radar where people still tried to catch me making trivial mistakes. I felt like myself again: I was taking risks, I was experimenting, I was trying to grow and improve myself and my staff. Finally, I was again fit for the position I held.

I made a conscious decision at that moment to create an environment where my staff felt comfortable coming to me and asking for help, says @CarmenPata. Share on X

I made a conscious decision at that moment to create an environment where my staff felt comfortable coming to me and asking for help. It takes a lot of courage to go to your boss and tell them, “I’m struggling. I have no idea how to do this.” Being able to ask for and accept help has been one of the qualities I try to develop because, as the Army displays in the confidence course, all of us need each of us.

Now, let me be clear: I’m not saying for you to hire incompetent people. Not at all. You have to hire quality people, encourage them to take risks, and put these staff members into situations where their professional skills, education, and background will not be adequate. Sure, you can let your staff struggle with situations that they have never been prepared for. This is something that I still do, at least for a while. I want them to feel the struggle and give them the time and freedom to use their creativity and talents to find the solution. Then, after a while, I come by and ask the staff member a simple question: “What can I do to help you do your job better?”

Two

Learn to Talk Last

A classic example of this plays out on TV, in movies, and in real life: In a boardroom, executives sit by rank. The most senior people sit closest to the head of the table, while the most junior people sit farthest away. One person comes in, sits at the head of the table, and says: “Here’s our problem and this is what I think the solution is. Now, what do you think?”

Is anyone surprised that the boss’s idea usually passes with an overwhelming amount of support, regardless of how good or bad the idea actually is? Of course not. When the meeting is over, everyone goes back to their area and talks about the decision. Some are happy, others are disappointed, and many are resentful. They are resentful because they had a better idea, but they never had a chance to express it. Sure, the boss asked, “Now, what do you think?” But we all know that doesn’t work. Once the boss presents their idea, who will have enough courage to disagree with it?

So how do you take advantage of letting people be heard? Learn to be the last to speak and to actually hear what other people say. This is not an easy skill to learn. In his lifetime, South African president Nelson Mandela had a reputation for being a great mediator and a wise leader, attributes he credited his father with teaching him when he was young. Mandela’s father was a tribal leader, and whenever there was an issue in their community, all the other leaders would gather in a circle, the problem would be brought to the group, and everyone would state their opinion. Ultimately, the person who had the final say would be the last to speak—and this skill, waiting to be the last to speak, is one that Mandela credited as key to his growth into a world leader.

How do you take advantage of letting people be heard? Learn to be the last to speak and to actually hear what other people say, says @CarmenPata. Share on X

Which brings us back to you and your staff. I’ll assume you didn’t just hire a bunch of “yes men,” but people who see the world a little differently than you do. These people are going to use their range of educations, experiences, and backgrounds to come up with different ideas or solutions to the issues that challenge your team. This is why diversity is important: to produce different solutions. Let your staff pitch their ideas before they can be influenced by your thoughts. You just might be surprised when they come up with an idea you would have never thought of.

Three

Understand Your Real Responsibility

As assistants, it’s our responsibility to get really, really good at our jobs. We apply all that formal education and our past experiences to become the very best coach we can be, and we are responsible for getting results. Our athletes (and their sport coaches) want to see improvements, and they demand that we provide those results. What I’ve learned, however, is that this very thought is the exact opposite of what constitutes a head coach’s job. We are no longer responsible for the results—we are responsible for the people who get the results.

There is a lot to unpack in that sentence. From my experience, the further up the promotion chain you go, the less time you spend doing the job you were originally hired to do. In our case, it means the less time you spend actually coaching athletes. Because we have to spend more and more time doing all of our other duties, we find people to help do the things we don’t have time to do anymore. Once we start getting people to help us, we start putting in guidelines and policies (or at least I did).

In my mind, I had to make sure that everyone who helped me worked within the plan for the program. Before too long, it felt like everyone was bogged down and my staff was asking me questions about every little thing. This happened because I imposed so many rules that they needed to follow, and the staff didn’t want to make a mistake and get into trouble.

Like I said, we do have to have some sort of boundaries. You just can’t walk into a bank and have the teller withdraw a million dollars when you only have $5 in your account. Nor should someone simply have carte blanche to do whatever they want within a program as an assistant. But the first thing that a new head coach should do is set up an environment where people cannot just survive their work day, but thrive in it. The real job of a head coach is no longer to simply get results from the athletes, but to take care of the people who are in charge of getting results from the athletes.

I’ll be the first to admit that people in our profession are very unique. We have decided to go into a field where working 60+ hours a week is the norm. We have decided to go into a field where having a master’s degree is a preferred job requirement, but we are not even remotely compensated for that educational achievement. We have decided to go into a field where many of us are being evaluated by people who do not understand our area of expertise.

In spite of all of these negatives, an overwhelming majority of us decide to stay in this field. Sure, we might change jobs, but we stay in the profession. That says something about the type of people strength coaches are. We shall pay any price, bear any burden, and meet any hardship because we really want to teach people to…what? To power clean? No, that’s not it. We choose to suffer these because we believe that there is something more noble than simply working for a paycheck. We believe in our own ability to teach other people to become the best possible version of themselves.

This profession is hard enough, and we don’t need the extra stress of a micromanaging head coach to compound it. What we do need is a head coach who will support their staff and help them grow professionally and personally along the way. When your staff feels supported and taken care of, then they have better interactions with the athletes, who will then have better workouts. When people have better workouts, they have better results, which makes everyone happy. All of this will happen when you realize the real responsibility of being the head coach is to take care of your staff, since they are the ones who have the most interaction with the athletes.

Use It Wisely

Now that you have gotten your head coach position, you are truly in a position of leadership and authority. You have the power to make other people do what you say, but you also have the responsibility to take care of the people in your charge. It’s not always an easy thing, to spend time teaching and nurturing people, and sometimes it blows up in your face. This is why you need to have the one universal trait of leadership: Courage.

Listen to people who have done things truly heroic, putting their lives on the line. When soldiers, police officers, and firefighters are asked why they rush into dangerous situations to help their colleagues, their response is almost automatic: Because they would do the same for me. Courage isn’t some magical attribute that some people have and some people don’t. What gives people courage is the knowledge that someone else will place themselves at great risk for them. Knowing that gives you the confidence to put yourself at great risk in return. In other words, your staff will take risks for you and your vision of your program only if they know that you will expose yourself to risks for them in return.

It takes courage to let a new staff member run with a new project. It takes courage to admit you made a mistake in a staff meeting. It takes courage to let other people voice their solutions to a problem and actually use their ideas. This is why being a true leader takes a lot of courage.

If you want to be a leader and be fit to hold the position that you now have, you have to let people struggle and grow, says @CarmenPata. Share on X

There is nothing riskier than letting one of your assistants struggle taking a team when you know, deep down in your heart, that you could do better than they can. But we all know that, unless there is struggle, there is no growth. Assistants don’t want to stay assistants forever, so they are going to have to grow—which means you have to let them struggle. If you want to be a leader and be fit to hold the position that you now have, you have to let people struggle and grow. But, as they grow, so will you.

Female Weightlifter

Getting Athletes on the Podium with Irineu Loturco

Freelap Friday Five| ByIrineu Loturco

Female Weightlifter

Irineu Loturco has a Ph.D. in sport science and a postdoctoral degree in Mechatronics Engineering and Mechanical Systems. He is the founder and director of the Nucleus of High Performance in Sport (NAR; São Paulo, Brazil), a high-performance training center that serves hundreds of top-level athletes from many different sports and develops social projects to help children and young people from low-income families.

Loturco has worked as a strength and conditioning coach in major Brazilian soccer clubs and with different Olympic and Paralympic sports, especially national teams. Currently, he is Professor of Methodology of Sports Training at the Federal University of São Paulo (UNIFESP) and Visiting Professor at the University of South Wales, in Pontypridd, U.K. Loturco has a large range of scientific publications with elite sport, and the vast majority of his studies involve professional athletes, many of them competing at the Olympic level.

Freelap USA: Hamstrings and glutes are vital for sprinting, but how do you train them dynamically outside of doing Nordic hamstring curls and barbell hip thrusts? Is it possible to use other exercises to stimulate improvements in posterior leg and hip strength?

Irineu Loturco: The hip extensors are particularly important for sprinting performance, as they “push the body forward” during the stance phase, especially during the acceleration phase. Besides the use of Nordic hamstrings and barbell hip thrusts, we regularly prescribe numerous other exercises in our training center to improve leg and hip strength in professional sprinters. These include different variations of back squats, weightlifting derivatives (e.g., squat clean and squat snatch from the floor with a deep catch), reverse hyperextensions, stiff-leg deadlifts, Romanian deadlifts (and single leg Romanian deadlift), hex-bar deadlifts, and lunges, among others.

As examples of “more dynamic exercises,” and supplementary training strategies, to increase leg and hip strength and power, coaches are encouraged to frequently use:

  • Resisted sprint training methods (e.g., sled towing)
  • Uphill sprinting (we have a 75-meter, 1% inclined track at our facility)
  • A combination of resisted and uphill sprinting
  • Wearable resistance apparel (attached to the ankle or to the leg, according to the training objective)

For all these methods or variants, we use a typical “limit of speed reduction” to define and prescribe the individual training loads. (The loads should not lead to a speed reduction >10–15%). We use this limit to avoid substantial changes in sprinting mechanics—especially in relation to hip mechanics, since too much load will, for example, increase contact time and impair hip extension. This strategy is also important to reduce the accumulation of by-products of metabolism (the “side effects” of training), as the majority of these athletes compete at an international level and thus have a very congested training, travel, and competitive routine.

In addition, specifically for hamstrings, coaches are recommended to regularly include in their routines eccentric box drops (with or without weighted vests) and eccentric backward steps. In a general way, all sprinters in our training center systematically perform these exercises, with some slight variations according to the coach’s criteria and methodology.

Freelap USA: Barbell tracking technologies are popular, but what mistakes do you see that coaches and researchers may not be aware of? With your extensive experience, what do you think the majority of coaches and sport scientists could improve on? I see you have used MPV with some of your research, could you elaborate on the reason?

Irineu Loturco: Before answering this question, let me say that I was honored to have Professor Juan José González Badillo as a supervisor for my Ph.D. project. He long ago described what we now know as the “load-velocity relationship,” a concept that gave rise to “velocity-based training.” I recently watched an interview with Professor Badillo on social media, where he said we were entering an unnecessary and exaggerated zone of study, comparing variables and relationships that, in essence, are already extremely accurate and consistent.

Generally speaking, numerous studies have shown very strong linear relationships (R² > 0.95) between load and velocity for the vast majority of exercises. This seem to be independent of the measures used (i.e., MV, MPV, and PV), which are, in turn, highly precise and consistent (i.e., CV ≤ 5–7%; ICC ≥ 0.90). In this sense, I use MPV as a base (although I use PV in some research that involves only ballistic exercises) because of the need to standardize only one measure for works involving different types of exercises, and because of the influence of the classical (and for me, unsurpassed) studies of Badillo and Luis Sánchez-Medina. In relation to coaches, I believe that we, as researchers, have the fundamental role of simplifying the training process by offering uncomplicated, accessible, and, above all, efficient strategies.

As researchers, I believe we have the fundamental role of simplifying the training process by offering uncomplicated, accessible, and efficient strategies, says @IrineuLoturco. Share on X

Strength training is part of the daily routine of athletes of different individual and team sports. Thus, any unnecessary minimalism or complication is not well received, and this can turn coaches away from the scientific field. From years of experience working with literally hundreds of coaches and thousands of athletes in different sports, I realize that many of these professionals really know what they are doing, but they base their strategies above all on subjective perceptions. Therefore, it is essential to present simple and viable training strategies, bringing effective solutions (and not unnecessary complications) to these professionals.

At this point, I think sport science has lost control over velocity-based training; in a war of egos, in minimalism. So, I think the biggest mistakes here are ours as researchers, and not with the coaches. At our training center, our premise is to guide coaches on the major (and critical) differences that exist when athletes train in different velocity zones and, most importantly, which directions to follow in each phase of training, according to the goals of athletes, adapted to the needs of each sport. This is independent of equipment or measurement, but stems from complete, applied, and “real” knowledge about the training process.

Thus, we have “uncomplicated” this process and keep moving forward on different fronts. This even allows us to publish studies with dozens of Olympic-level athletes, including Olympic champions and world champions. In this way, we have achieved significant results, and today we serve a huge number of professional coaches and athletes, not only from Brazil, but from different countries in South America. For me, this is the fundamental and most important role of sport science.

Freelap USA: HRV as a monitoring tool requires a lot of interpretation and experience with athletes. Do you have any recommendations for teams that don’t have a sport scientist but do employ crafty fitness coaches?

Irineu Loturco: I agree with you. In my opinion, as with any other variable used with the purpose of monitoring athletes’ training status and evaluating adaptations (responses) related to training, HRV requires a solid statistical background for analysis and interpretation. Although HRV is a time-saving variable in terms of data collection (e.g., depending on the methodological approach, it requires less than five minutes), when collecting HRV for a team with athletes of distinct characteristics and responses to the training sessions, appropriate interpretation of the data is crucial.

Currently, there are several devices that facilitate data collection and promote a quick demonstration of the HRV outputs. In addition, more recently, several valid and reliable mobile apps have been developed with the purpose of increasing the practicality of the HRV assessment. However, a “simple HRV result” does not represent anything without understanding the training and competitive context and properly interpreting this data. For this reason, no matter which variable you are collecting, proper data management and interpretation are crucial in any situation.

For this purpose, for example, the use of practical statistical tools such as magnitude-based inferences can facilitate the analysis and interpretation of variables that require more detailed and robust interpretation. Fitness coaches can develop their own spreadsheets with the automatic calculation of the smallest worthwhile changes and confidence limits, which may allow them to perform an individualized analysis of the responses of each athlete and use this in their decision-making process in terms of training prescription and load control. Although it is not easy to customize and manage these spreadsheets (especially when the data is collected on a daily basis), this facilitates data analysis and increases the quality of interpretation. At the Nucleus of High Performance in Sport, we have a team specifically dedicated to supporting coaches and sport scientists with HRV measurements and data interpretation.

Freelap USA: Going more local to muscle groups rather than systemic with the autonomic system, can you explain how to use tensiomyography with teams with at-risk muscle groups over the week for soccer or rugby?

Irineu Loturco: Tensiomyography (TMG) is a very practical and useful method; however, in our facilities, due to our natural expertise and objectives, we primarily use this measurement to provide insight into muscle fatigue, readiness for training, and training adaptations. As you know, these insights are not always related to injury risk, and in fact, as a research team, we do not have studies that demonstrate (or even evaluate) the role of TMG in injury prevention. On the other hand, we frequently use this measurement as an alternative tool to provide coaches with more detailed information regarding acute and chronic training responses, on an individual and (in some specific cases) daily basis.

We frequently use TMG as an alternative tool to provide coaches with more detailed information regarding acute and chronic training responses, says @IrineuLoturco. Share on X

As a passive and rapid evaluation, TMG can be used in different situations, independent of the training phase and status, which is a great advantage in high-performance training settings. More recently, especially with professional soccer and rugby players, we have been using the TMG-derived velocity of contraction (Vc), a measure that simultaneously combines three different TMG outputs (muscle displacement, delay time, and contraction time), thus providing a more comprehensive view of the training adaptations (and changes over time).

In summary, among other things, we have observed that both increases and decreases in Vc are directly (and respectively) related to increases or decreases in speed and power-related capacities. We also regularly use this measurement with elite sprinters and jumpers, especially close to competitions, in order to precisely adjust their individual training loads and assess readiness for competition.

Freelap USA: Developing change of direction ability throughout a career with different age groups is tricky. What advice can you give coaches and clubs that try to properly develop this speed quality in their athletes?

Irineu Loturco: This is a very good question. We work with hundreds of athletes from distinct age categories and numerous sports. Nonetheless, one issue that is very common among all sports is that, from younger to older categories, these athletes do not become more efficient in changing direction. Although they “usually” improve their linear sprint capacity throughout the specialization process, the “change of direction deficit” (a measure that represents the additional time that one directional change requires when compared with a linear sprint over an equivalent distance) appears to progressively increase with increasing age.

One common issue among all sports is that, from younger to older age categories, these athletes do not become more efficient in changing direction, says @IrineuLoturco. Share on X

There is a series of issues that may be associated with this phenomenon, including mechanical aspects, as faster (and heavier) subjects probably present increased sprint momentum (thus, inertia), which may hamper their ability to execute sequential accelerations and decelerations when changing direction. But besides this, in my opinion, there is another critical factor contributing to this “lack” of improvement throughout maturation: the absence of effective and specific speed training practices, especially those focused on the context of the game. Despite the growing attention given to neuromuscular training in recent years, clubs and academies generally concentrate their efforts on developing training programs primarily related to injury prevention or to the development of more traditional speed and power qualities, such as straight sprints and vertical jumps.

As Ian Jeffreys states in many of his works, the transfer of these capacities to specific “game speed” cannot be guaranteed. Therefore—and, again, in my opinion—federations and youth sport academies should include in their scientific and technical staff, practitioners whose fundamental interest (and ability) is in understanding and improving the speed-related performance of young athletes, specifically focused on the context of the game.

Youth Soccer Scrimmage

By Eric Udelson

It is no secret that, in the past decade, soccer in America has seen significant advancement in terms of popularity and also its ability to cultivate talent, as evidenced by the U.S. Men’s National Team ultimately reaching the highest level of international soccer. Look no further than Christian Pulisic, who at only 20 years old was recently acquired by Chelsea F.C. of the Premier League in England (widely considered the best league in the world) for $73 million. So, relative to the standing of American soccer a few years ago, there has been major growth, yet there is still significant work to be done to catch up to dominant nations like Brazil, Spain, and France.

Although the development of young soccer talent has improved, there still are some very concerning practices and beliefs from coaches and parents that impede athletic development. As a player myself, I’m well aware that success in this game is about much more than athleticism. But why not maximize our young players’ physical capabilities so they can be stronger, faster, and fitter athletes while simultaneously making them more injury-resistant?

This article will detail various issues with America’s development of youth soccer players that only seem to hinder athletic development, and it will provide potential solutions for this critical aspect of the future of American soccer.

The Scope of the Problem

Among the plethora of issues that exist with youth soccer development in America, one of the premier issues is the overscheduling of games in a season. Specifically, this issue refers to players having too many games concentrated in a short time period rather than having too many overall games. This distinction is important because the central problem is the insufficient rest period in between games and not the specific number of games in a season. Similarly, you could also add that the ratio of training sessions to games could be altered to having fewer games and more training.

During my progression through youth soccer growing up in Massachusetts, I had firsthand experience with this type of chaotic schedule. From the ages of 12–16 years—extremely key years in athletic development—I played on the pre-academy team for a club team called the FC Boston Bolts. The other teams in our division consisted of clubs that were spread out along the East Coast, going down as far as Pennsylvania, so naturally there was a fair amount of travel involved.

The problem lay in the fact that there were multiple teams in the Pennsylvania area and multiple teams in the Boston area, so when it came time to travel down south to play these teams, the league decided to create a double-header format with a game on Saturday and another on Sunday. The logic behind this scheduling made sense from an efficiency standpoint, as making just the one trip to Pennsylvania was already expensive and time-consuming, especially when discussing youth soccer for 13-year-olds. Yet, when speaking in terms of youth athletic development, the concept of competing in 90-minute games on two consecutive days is criminal and most likely destructive.

Even more outrageous is the format of youth soccer tournaments at the town level. For me, this was during ages 9–12. We would have tournaments that consisted of three games per day during a two-day period! Even as a young kid with all the energy and enthusiasm in the world, I vividly remember slogging through that last game of the day really just trying to cross the finish line rather competing at my best level.

The Baggage of Competition

Why is the over-concentration of games so damaging? Intriguingly, on the surface it may not seem so destructive, as young pre-adolescent and adolescent kids seem to be significantly less affected by an overload of volume. Better yet, young kids also will most likely maintain the same enthusiasm while being overworked compared to college athletes. When you’re that young, you just love playing in games and most likely won’t be as transparent about sore muscles or aches/pains. Nonetheless, the fact remains that the large number of games in a short time period causes excessive fatigue and stress on youth athletes during possibly their most important period for athletic development.

This issue plays out in the classic “domino effect” format. For instance, if a 14-year-old player plays two full games during the weekend, they build up in inordinate amount of fatigue that requires more time than normal to recover from. Therefore, when they report to training on Tuesday, they will likely not have recovered to an adequate level to compete again and will therefore be performing at a lesser intensity (intensity referring to explosive change of direction movements, sprint speed, neuromuscular firing rates) than is normal.

Training with this type of residual fatigue is not so harmful at first, but if made a habit throughout an entire season, it can take on more serious decrements and could certainly create a risk for overtraining syndrome. First among the decrements could be a decrease in explosive movements regarding maximal velocity and change of direction, both obviously invaluable markers for an athlete’s performance in soccer. More importantly, in general, if an athlete habitually trains the body at lower speeds than normal—which occurs when shouldering residual fatigue—the muscles will create a new norm, seeing as there is less demand for explosive movements. Getting into the biology, this could happen through a translation of type II muscle fibers to less-explosive type I fibers within their muscle on a molecular level.

Other than performance decrements, overscheduling games during crucial adolescent years could increase the risk of injury. During an athlete’s adolescent years, their tissues (muscles, tendons, ligaments) are still developing in terms of size, and also in terms of integrity. Take, for example, a college soccer player who has two training sessions in one day for their preseason versus a 13-year-old boy who participates in a double-header like that of my personal example.

Assuming no previous injury for either party, the college athlete would be better able to handle high workloads, as they have more collagen content in their tissues, giving them a greater ability to withstand high levels of pounding on tissues from high-intensity exercise without sustaining injury. Conversely, the 13-year-old is in the midst of puberty, which is, among other things, a time of immense anatomical development. His tissues are not as densely packed with shock-absorbing collagen, creating a greater chance of the tearing of tissue fibers from continued stress.

How to Fix the Problem with Realistic Solutions

There are simple solutions for this problem, many of which rely on rational scheduling and therefore manipulation of workload. This could mean not having teams from Massachusetts in the same division as Pennsylvania teams, as there would be no need for a double-header weekend if the farthest the Massachusetts team had to travel was to New York, for example. Next, there needs to be a readjustment of the ratio of trainings to games. The ratio that should be maintained is roughly 3–4 trainings to one game per week. That way, workloads can be manipulated from session to session, depending on fatigue levels, to provide for optimal performance in the sole game of the week.

Lastly, even though some youth teams may understandably struggle for these resources, the concept of monitoring fatigue/soreness levels for youth athletes could be very useful. This is true even if the monitoring only consists of an online survey for players to fill out and doesn’t involve any sort of advanced technology. This could provide for the accurate progression of intensity throughout the week of training, instead of simply guessing based on the naked eye.

Besides irrational scheduling, an additional issue that plagues athletic development in youth soccer is the development of poor running mechanics. The correct sprinting mechanics is something that must be taught and then reinforced, but youth soccer players seem to almost completely ignore it. This means that players will develop various bad habits and maintain those habits until they are shown otherwise.

My belief is that most of these habits develop from players thinking they are employing mechanics that are advantageous to the game of soccer. For instance, a common error for youth players is that, while sprinting, they will be hunched over with an arched back and shoulders shifted forward. This habit might be advantageous while dribbling, as it’s important to have an athletic, crouched stance to ward off defenders, but while sprinting, these principles only reduce speed. Instead, during maximal velocity sprinting, players should be taught to be upright with shoulders relaxed and shifted back.

Another example of poor mechanics common with youth soccer is players having short, choppy strides. Because of these choppy strides, these players cannot drive their knees to an adequate height, which in turn detracts from the amount of force they can generate into the ground, ultimately reducing speed. Again, this technique is quite useful while dribbling or during any situation where they need a quick change of direction. However, in terms of sprinting, players should adopt longer, more power strides, particularly focusing on driving their knees vertically, combined with aggressive arm action.

Of course, young kids most likely will not want to hear a technical explanation of proper mechanics, so a simpler takeaway is that moving your feet faster does not necessarily mean more speed. I think it’s possible that youth players try to emulate their favorite professional players who are undersized but lightning-quick, like Lionel Messi, and in an attempt to appear faster, these youth players actually develop inefficient mechanics.

The central key to developing correct sprint mechanics early on and ridding players of bad habits is, first and foremost, to separate their sprint work from their training with the ball. This means that, other than their team training that involves ball work, players should consider adding a few sessions per week, or even 30 minutes before a team session, that is completely devoted to speed work. This way, they can develop mechanics within a sprinting context and not within a soccer context.

It’s crucial that sprint work is completed without the ball because it gives kids a chance to really hone their mechanics without having to worry about controlling a ball simultaneously. Developing sprint mechanics can be a gradual process when starting from scratch like many youth players do. Sometimes it will require an entire session’s worth of reps to make progress on one, single aspect of sprinting, such as arm action or staying upright. Therefore, if they’re to make progress, youth players cannot be overstimulated with an overload of cues or the addition of a ball. Players should be trained to sprint like sprinters, not like soccer players, which requires the right environment and belief in the gradual process of motor learning.

Changing the Culture and New Horizons

Speaking to what is limiting athletic development in youth soccer, we have discussed poor scheduling that leads to undue fatigue, as well a lack of emphasis on proper running mechanics. Yet there is another deficiency of the American youth soccer system that is more of a culture problem. Specifically, I’m referring to the widespread mistrust toward resistance training for youth soccer players.

Unfortunately, a negative stigma has developed around weight lifting for youth players that is not founded in objective science or factual evidence. It seems that this mistrust is based on various misconceptions about resistance training for youth athletes, the first of which is that weight lifting is unsafe for adolescents and could cause injury. This perception is, in fact, completely untrue, and the truth is quite the opposite. Assuming that loads and scheduling are handled rationally, a resistance program could actually prevent injury.

As discussed before, the research shows that if an athlete commits to a consistent schedule, weight lifting will improve tissue integrity as well as bone mineral density, both markers that aid in preventing injury. Besides better preparing your tissues, participating in plyometric exercise over a period of time can also prevent injury. For youth players who normally have limited experience in the weight room, the main focus of plyometric exercise centers around landing mechanics. Learning how to properly absorb the ground force after being airborne has been shown to be crucial for preventing knee injuries, specifically valgus knee.

Other than an unfounded fear of injury, there is also the misconception that resistance training makes young athletes lethargic and bigger in size. Although it is true that when starting a lifting program at an untrained state the athlete will most likely gain some lean body mass, this will most likely not cause any losses in quickness or speed. The central flaw in the association between being lethargic and lifting is that people assume that lifting, by definition, is based around hypertrophy (growth in muscle size). The reality is that hypertrophy is only one of the many possible training goals around which strength coaches can form a program.

For example, a freshman college football player may require more muscle size to be able to compete at his position. However, with youth soccer, it is all about providing them with a weight-lifting foundation that can yield performance improvements without disrupting natural growth by adding too much load or overcomplicated exercises. It’s very simple to choose certain exercises and devise set/rep schemes that will produce speed and explosiveness results for young soccer players while still staying light and shifty.

Any half-decent strength coach will respect a young player’s early stage of development and form their program around soccer-specific workouts that will improve the player’s athletic prowess without gaining too much mass to create any lethargy. A properly managed lifting program will also improve a young athlete’s neuromuscular skill. A growing awareness of the body and its movements is crucial for sport performance, as it allows muscle actions to be executed with more fluidity and less energy, which is distinct from physical measures like improving speed or agility.

Of the current issues that seem to be limiting youth soccer athletic development, reversing the stigma associated with lifting may prove the most challenging. Unfortunately, there will always exist a certain population that will hold its beliefs even if objective scientific research shows otherwise. The best we can do as members of the sports science world is try to educate and debunk any irrational fears that are held by youth players, coaches, or even youth player’s parents.

One more important step in convincing people who have set feelings about weight lifting is attacking the source of their feelings. Many of these people who need convincing view resistance training as an activity based around machismo—lifting massive weights to obtain the largest muscles possible. If we can educate people that resistance training for youth players is a carefully crafted process that will be soccer-specific and tailored toward developing a strength foundation and injury prevention, considering a youth player’s early stage of development, then maybe we can change the narrative.

What the Future Holds

Although youth soccer has made great leaps in terms of being taken seriously on the world stage, we can do better to develop dominant young athletes. This means connecting those who are uninformed to science-based methods that have been shown to lead to major performance increases, whether that concerns improving speed, conditioning, or injury resistance. Only relatively recently have there been MLS teams that create full-time positions for sports scientists; meaning that the field is being taken more seriously, with the intention of obtaining any competitive advantage possible. This sort of mentality and respect for performance science needs to be adopted by youth soccer so that we can cultivate dangerous athletes and hopefully start on the path to rival the best soccer nations in the world.
