Basketball Dunk

7 Philosophies on Increasing Vertical Jump Skill and Power

Blog| ByJoel Smith

Basketball Dunk

When it comes to validating one’s self as an athlete, jumping is the first request on many training priority lists. Think of the famous sporting feats that are etched in our memory:

  • Vince Carter leaping over Frederic Weis in the 2000 Olympics for the thundering slam dunk finish.
  • The famous front-flip touchdown by Jerome Simpson of the Bengals.
  • Bo Jackson leaping and running up the outfield wall following a running catch against Baltimore.

Sure, it’s embarrassing to get beat down the court or on the open break by an opposing player, but it’s far more humiliating to get dunked on (Weis lost the opportunity to play in the NBA due to his notoriety as the 7 foot guy who got jumped over), your shot blocked, or a spike rammed down your nose. Nobody is “posterized” by simply getting beat by an offensive player downfield. It is as if Stan Lee decided that the superhero version of the modern athlete was one with unbelievable jumping ability. The marketing engine, as it exists, likes to cater towards those athletes with these superhero aspirations. Who wouldn’t want a program that will turn them into the Batman of athletes for only $67?

Speed wins games, but jumping seems to be the envy of those who want to impress. It also doesn’t hurt the cause of becoming a better athlete. Real vertical jump training with the goal of advanced performance can be muddy waters, particularly through the efforts of those who have seized up much of the available information with marketing based information, directed towards novice athletes.

The goal of this article is to provide some philosophies and guidelines for the rest of us, those who are interested in the long-term process of sport mastery, and the journey of taking athletes to their best possible performance. These points are often left up to debate in the various training forums and roundtables of the world on the subject of increasing vertical leap ability so I am sharing my thoughts on them, all in one place, right here. I derived these from my time as an athlete, a track coach, a strength coach, as well as in my work with online clientele of various backgrounds.

Let’s start with a common point that most coaches already know, but one that may need a bit extra clarification in regards to jumping.

One

Exercises are in your program for a season, and sometimes a lifetime, but are only a means to an end.

I hear it all the time:

“You need to be doing X exercise if you want to jump higher.”

In athletic performance training and particularly vertical jump training, there is a recurring theme of “exercises”. Often athletes swear by this or that exercise, or exercise sequence, in regards to their athletic ability. Track athletes often carry with them an exercise that “they need to be doing” because there was “this one time” in their athletic career when they were performing that particular exercise and competition went well for them.

The truth is that there is a window of time each exercise will be effective in providing a significant short-term boost to vertical jumping ability, largely due to the skill improvement that the particular exercise delivered to the athlete’s jump technique. Once the skill improvement is transferred, there isn’t as great of a need to keep introducing the exercise in such a volume during the rest of the athlete’s career.

For example, as far as speed training is concerned, I have found that the barbell hip thrust is a fantastic way to get an athlete’s glutes up to speed in terms of activation and pelvic posture, but once I have brought an athlete to the appropriate activation level, bringing their max from 500lbs to 550lbs by continual focus on that exercise is probably a waste of time. With the new level of activation gained from hip thrusts, many of the other exercises that they do will help to maintain that improved strength and size of their posterior. It is a similar story with jumping.

The following are some examples of traditional jump exercises, and the corresponding skill of the jump that they can bring up to speed.

  • Jumping rope provides a rapid boost in ankle function and stiffness for an athlete who tends to live on their heels.
  • Squatting provides a rapid boost in athletes who need to learn to apply forces for longer periods of time to the ground in two leg jumping. (Vertical jump height off of two legs is a stark contrast to one leg as the amount of time that an athlete can input force into the ground directly correlates with the final vertical velocity of the jump).
  • Plyometrics provides a rapid boost in performance in athletes who lack stretch shortening cycle efficiency and general foot strength.
  • Pistol squats provide a rapid boost in leg stability and linking of the feet and hips.
  • Olympic lifting gives an immediate infusion of posture and coordination through triple extension of the hips, knees and ankles.
  • And so on and so forth.

These exercises will provide a rapid boost for a period of time, as they but in order to attain long-term progress, many of them will need to take a back seat to what is truly important. Clearly they should be kept in the program in some form, or rotated to prevent a lack of accommodation. Also, we know that a rotation of exercises that are very close to velocity and mechanics to the primary exercise are vital in long-term athletic improvement for motor learning and accommodation reasons, so strategic use of exercises will also rotate based on these needs.

Although many exercises must be kept in a program for the purpose of maintenance in particular qualities, the primary areas that truly need to be addressed for continual jump improvement during all periods of specific and competitive preparation in order of importance are:

  • Specific work capacity in the type of jumping that one wishes to improve (the ability to jump maximally and in enough volume to deliver repeated, specific training effects).
  • Speed. Specifically, acceleration.
  • Rate of force development in the specific motor pathway an athlete utilizes to jump. Quick jumpers prefer specific plyometric based movements, while power jumpers ofen prefer specific barbell oriented movements such as squats or barbell step ups).

Two

Understand the squat to bodyweight debate. Lift for explosiveness and complimentary benefits, not to hit a magic number.

“To die as a warrior means to have crossed swords and either won or lost, with no consideration for winning or losing.” — Miyamoto Musashi

What in the world does the above quote have to do with lifting for athletic performance?

Well, aside from giving me an excuse to put a samurai reference in this article, it also represents a nice ideology for the purpose of strength training as far as increased athleticism is concerned.

Just like the warrior who enters battle for the ritual of combat, and not so much the determined outcome as a means of validation, the athlete who enters strength training does so for the transfer of skills to the field of play, and not the outcome goal of lifting itself.

Why would anyone validate their ability as an athlete based on a means used to train, and not the actual competition itself? This happens regularly with strength. Although barbells are a great and often indispensable training means, when the urge to utilize the barbell as a form of athletic (or personal) validation creeps in, the whole training system can be thrown out of balance.

This mentality can also cut athletes career progressions short as athletes thrown through the barbell grinder in high school or college can often scrape out nice performances for that particular time period, but struggle and regress in the next phase of their athletic journey.

Another thorn of this mentality, particularly with high school athletes, is that those high school athletes who responded well to year-round heavy lifting in high school will mentally rely on this type of work as a means to success in their college years. This often spurs a negative cycle of regression on their part, which the solution to is often, “more heavy lifting!”.

As far as improving athleticism, lifting weights serves the purposes of:

  • Improved posture
  • Body awareness
  • Coordination
  • Joint stability
  • Potentiation of proximal speed and power training sessions
  • Positive hormonal changes (testosterone and growth hormone)
  • Increased cross-sectional area of relevant muscle fiber pool (when done correctly, and there is a limit to this based on an athlete’s genetics)
  • Increased strength at key joint angles and torques

Looking at these benefits it is easy to see that strength training is an important tool to making the rest of training better; any of the benefits are those that can easily be “maxed out”, early in their use or an athlete’s career. For example, an athlete will reap immediate body awareness, explosive coordination and postural benefit from a well-designed lifting program, but those benefits will only take them so far. There isn’t an infinite improvement rate as far as posture and coordination are concerned.

As far as vertical jumping goes, athletes with a great squat to bodyweight ratio will jump higher than their weaker counterparts, all other factors being the same. There is an important chicken-or-the-egg consideration to make with these athletes, however. Athletes who are naturally strong and explosive will experience a rapid train of improvement in barbell exercises, along with lots of psychological momentum. Athletes on the weaker end will find rapid improvements via lifting, especially in the motor benefit realm, but their results will taper off far sooner than their stronger counterparts. Unfortunately, rather than playing to their more natural plyometric and elastic strengths, these weaker athletes will sometimes put their heads down and strive for a particular lift number that hamstrings (sometimes literally!) their long term athletic progress.

“I was pretty average until I decided to work hard to hit that 2.5x bodyweight squat, after which I won the Olympics,” said no athlete ever.

Athletes who tend to improve their vertical jump the most by focusing primarily on the lifting portion of their program are, more often than not, athletes with a lot of fast twitch muscle mass, who generally jump in a style resembling their lifting. Their lifting makes their jumping better (to a point), and their jumping makes their lifting better. Realize that many athletes are not built like this.

Lift maxes are a trick of sorts. Maximal strength often indicates the functional motor pool available in an associated movement, but intensely pursuing maximal strength doesn’t transfer well to speed based activities. The goal in lifting to bring maxes up that help athleticism is to do so in a way that doesn’t look like you are actually training for it; lots of powerful work in the 60-80% range, coupled with plenty of explosive plyometric, jump and sprint work. Believe it or not, many explosive wired athletes will find that their lift maxes will actually go up by following this methodology over a powerlifting style of training. Bottom line, speed builds useable strength more than strength builds speed.

Three

Use Olympic lifts for skill development and speed, not to end up on AllThingsGym.

As long as we are on the topic of lifting, find me an NCAA strength program that doesn’t use any Olympic lifts. The Olympic lifts can be very effective in the right context for building vertical jump related qualities, but they can also be lousy when they are worked in the wrong direction with the wrong cues, especially in athletes seeking to break through to the higher end of their genetic abilities.

Let’s make this as simple as possible and talk about the benefits of an Olympic lift in regards to vertical jumping skill. Regarding vertical improvement, any lift is only as good as it can improve the skill of a jump in an explosive manner. Here are the positives of Olympic lifting:

  • Teaching coordination in triple extension.
  • Providing a new set of motor instructions in regards to explosive concentric triple extension.
  • Teaching basic force absorption qualities in the catch.
  • Teaching advanced force absorption qualities, in transfer to two leg jumping, in the full catch.
  • Teaching posture in conjunction with explosive efforts.

An Olympic lift is a “jump”, but with one caveat: there is a bar that manipulates the athletes’ center of gravity (just like any barbell lift). Although a proper Olympic lift is done where the bar never passes more than a couple of inches away from the body, this is often done in-correctly more times than it is done correctly.

Getting into the 1RM race as far as cleans are concerned is also a battle that many athletes will eventually lose when it comes to building a better vertical jump. In order to bring a clean or snatch to its own highest level far past the initial complimentary benefits, the body must adapt itself to a different set of neural instructions that jumping requires, especially in regards to the feet (which we’ll get to in the next point).
Bryan Mann, in his great book, Velocity Based Training, recommends keeping a bar speed of at 1.2-1.4 m/s on cleans with perfect technique, the bar never straying far from the body. Doing heavy and relatively slow cleans with a bad bar path is one of the best ways to keep an athlete below the rest of the crowd, as this type of work has zero, or even a negative transfer to vertical jump height.

Four

Teach the feet.

In nearly every athlete I train who has a lousy standing vertical jump, the primary deficiency isn’t one of power, but rather one of foot function and force transfer through the torso. I have female high jumpers clearing 5’10 who regularly vertical jump under 20” because of ankle function. For high jump, this isn’t hurting them (and I am not on a mission to improve these girls standing jumps), it just reflects itself in the way that they jump off of two feet, as their primary reaction in directing force though the ankle is based around negative shin angles to perpendicular shins, where standing jumps rely more on positive shin angles.

Many athletes who have a well-rounded athletic background have pretty good foot function in regards to jumping. It is often over-specialization, coupled with the over-use of standard barbell training performed on a regular basis that can cause dysfunction in this area. Wearing shoes all the time also tends to put a damper on fast, reactive feet, as the plate of the shoe causes foot neurons that usually fire individually, to all wire together in one brute reaction to the ground.

In athletic performance, the faster an athlete can direct pressure to the big toe, and the more powerful the extension of the plantar flexion, the higher an athlete will jump. When an athlete lowers their frequency of re-enforcing this quality, and starts to spend two or three days a week performing exercises where they focus on directing force away from the big toe, or delaying it until the very last second, such as the way that cleans and snatches are often taught, this can wreak havoc on vertical athletic qualities. I see this all the time when we test the jumps of strong collegiate athletes who have been on a regular lifting program through high school. The ones who display the best vertical jump mechanics in the lower leg are often those who haven’t lifted much in their past, and played a jumping sport in their earlier school years.

So what to do?

The solution here is to make sure that athletes are being cued correctly in lifting activities (not lifting through the heel, and keep plenty of lifts that allow for some extension through the toe at the top of the lift), and perform lifts in a low enough volume as to not interfere with the correct lower leg action. It is also good practice to mix and superset barbell work with exercises and drills that do encourage the correct foot function, such as low-level plyometrics, assisted jumps, and lower leg jump drills. If I have the space, I’ll always superset Olympic lifting sets with a few vertical throws, focusing on complete ankle extension, or low-amplitude speed bounding, depending on the vertical outcome goal.

I’ll also say that many of these exercise prescriptions may be a bit primitive in light of Chris Korfist’s ankle rocker drills, while are one of the best new areas of jump training I have read in a long time, and they can restore foot and ankle function in a hurry.

Five

Know how to do a depth jump correctly and use energy efficiently.

If you look up “depth jump” on YouTube, be prepared for a cluster $%& of the highest magnitude. Depth jumps are rarely taught the way that they should be. I was fortunate to come across a vertical jump program (The Science of Jumping) when I was in high school that revolved almost entirely off of the correct performance of the depth jump exercise and its variations. Here are some common faults in typical YouTube videos on the topic:

  • Improper posture during the drop and land phase (often looking down).
  • Improper or minimal use of the arms (very small or non-existent arm swing).
  • No emphasis on landing softness whatsoever. No emphasis on where the foot pressure should be (the balls of the feet, and possible initial mid-foot pressure for single leg jumpers).
  • No emphasis on landing stiffness. Many athletes go into far too much knee flexion upon landing. Since the goal of depth jumps is rate of force development under increased load, knee flexion should be less to allow less ground reaction time.
  • No emphasis on the need for maximal upwards explosion on each repetition (this is the number one offense). Depth jumps are maximal efforts. In order to maximize upwards explosion, an outcome goal, such as an overhead target (for force) or a collapsible hurdle (for rate of force development) should be implemented. Athletes should seek to improve these outcomes throughout training sessions.

Let me talk about one aspect of depth jumping, and plyometrics in general, that coaches and athletes need to know: smoothness.

Good jumpers… really good jumpers, have one main thing in common. They make their jumps look incredibly smooth and easy. Good jumpers are quiet. This is something that is easy to say, but rarely put into practice. Check out this force/time graph of a novice jumper vs. an accomplished jumper to see what I’m talking about from a force perspective.

Novice versus Advanced Depth Jump
Figure 1: The grey shaded line represents Ug the Ogre’s heel-heavy landing, followed by an attempt to reverse the movement to vertical. The black line would likely represent a well-trained ninja performing a silent depth jump, with no passive jump forces present, and an efficient energy conversion.

What is the best way to improve one’s ability to produce force efficiently? A plyometric progression, starting with correctly coached drop jumps. Drop jumps (dropping from a box of appropriate height with an emphasis on landing mechanics) is a great way to teach force absorption. Once an athlete knows how to do this right, then to make lasting changes, a somewhat high volume of work is needed to wire it in. This is where submaximal plyometrics, coached with the same cues as the drop jump can help to gear an athlete’s nervous system and muscle-tendon structure towards transferring force in a more efficient manner.

Six

Understand the difference between body types in training.

Not every athlete is destined to squat twice their bodyweight. Not every athlete is born to master a depth jump from a 1 meter platform. Athletes need to eliminate weaknesses that are liabilities to their jump performance, but they shouldn’t pursue their weaknesses past this point to achieve their highest vertical potential.

Ultimately, athletes are built, and subsequently, developed for a particular jumping style. Through their adolescent development, their neurons that fired together to form a particular platform of movement, wired together to make that movement more powerful in their maturity.

Imagine taking a competitive swimmer at age 22, who had no real land based sport background and expecting them to be able to perform a technically perfect triple jump within a few months, or even years! Imagine taking a competitive triple jumper at age 22 and expecting them to perform a perfect butterfly stroke! Once the way our bodies tend to move are “wired in” those sequences generally represent the most powerful way that a person can move and apply force, and future specialization in the body’s current weakness is an impossibility.

When an athlete learns to produce force in a particular manner through adolescence (this is usually done in accordance with the athlete’s individual strengths) these patterns are wired in, and it becomes impossible to wire over it with another pattern that eclipses the old pattern in terms of power and efficiency. Athletes sprint and jump from just a few years old, so these patterns are very hard wired. Granted, there are technical refinements that can and should be made to anyone (otherwise, we might as well give up coaching!), but in general, wired movement patterns are hard to break.

What I am really talking about here is that some athletes will utilize little knee bend and elasticity in jumping (they often make good high jumpers and single leg jumpers), while others use considerable knee bend (they tend to make good 60m dash athletes and football players). You can’t take either of these athletes and expect them to jump like the other. In the same vein, you can’t take one athlete and expect that training like the other is going to bring them to their highest potential.

Seven

Don’t stop playing team sports and realize it’s power as a maximal jump incubator.

Within team sport play comes a wealth of explosive movement patterns. The highest levels of explosive power as exhibited in jumping are the product of other more basic movement patterns found in sport, such as the acceleration found in the jump approach, or the rapid decelerations that the lower limbs encounter during the absorption phase of the jump.

Team sport play also helps to maintain elasticity and build stronger lower legs, ankles, and feet. They deliver some of the strength that can be built only through repetition. The constant, rapid fire cuts, accelerations, quick hops and outcome based sport movements (such as jumping for a blocked shot) offer a unique training stimulus that can’t quite be attained via traditional training methods.

Remember, training in many cases is putting together very close variations of the primary movement you are trying to improve. In the scope of jumping, an athlete is getting plenty of jumps, no two of which are exactly the same which builds a bigger “bank” of motor patterns that the body can use to create a stronger movement. The variety also prevents injury, and perhaps of the greatest benefit, utilizes the important principles of fun and competition. Anytime you can make hard, effective work fun, it is generally a win-win.

Although experienced jump athletes who are specializing in something aside from basketball, volleyball or football need a base of team sport play in their younger years, they clearly shouldn’t be playing games constantly in their time of specialized performance. Despite all this, they should never completely lose touch with their team sport roots. Matt Hemingway re-vitalized his high jump career through his love of basketball in his later years of competition. A few 30 to 45 minute sessions of off-season, controlled team sport play for a few sessions a week goes a long, long way in keeping the movement bank of track and field jumpers full for their long competitive seasons. (Side note: hurdling is a great way to keep the movement bank full with slightly less risk of a rolled ankle)

Conclusion

My vertical jump journey, and the way that I coach athletes has been heavily influenced in some way, shape or form by the above principles. Most of them took around a decade for me to truly understand, but now that I do, I am a better coach and mentor for it. Each of these points on their own can be helpful. Together, they can make a great difference in producing the next great aerial touchdown or center-clearing dunk, or at least, the aspiring junior athlete who finally impresses his friends by shoving the round-ball through the rim.

Women 100 Meter High Hurdles

What Are the Real Elements of “High Performance?”

Blog| ByChris Gallagher

 

Women 100 Meter High Hurdles

Mladen Jovanovic Tweet

This tweet from Mladen Jovanovic, football physiologist at ASPIRE Academy for Sports Excellence, and the responses it generated illustrate a subject many who work in competitive sports environments are pondering.

From my knowledge of institutes in the UK, any university can designate its student gym as a “high-performance” center, as if such a grandiose title gives the impression that anyone other than the BUCS (British Universities and College Sport) competing football team trains there. There are of course some genuine high-performance facilities attached to universities with elite athletes training there. However, that does not change the fact that many institutions abuse the title.

High performance is not something you can justify by simply giving yourself, your institution, or facility that title. So, is high performance about the equipment and facilities in which you work with your athletes? The latest equipment certainly adds value to your program. Having velocity-based training (VBT) tools like GymAware, Tendo, or Push Bands advance strength and power training in your gym. Guys like Bryan Mann, Dan Baker, and Mladen Jovanovic or his articles, “The future of Velocity Based Training” or “Velocity Based Strength Training” put out quality information on how these tools can enhance your athletes’ training programs.

Advanced GPS Systems such as Catapult provide coaches and sports scientists with a wide array of sports analytics information. Performance management systems such as Omegawave allow you to monitor training, holistic, and lifestyle stress and readiness to train so you can adjust your training program if need be.

You can go on and on about the wide array of different technologies constantly being developed and updated to offer anyone involved in athletic performance development all the information they could require. But coaches and athletes were achieving world-class performances in years gone by without all this data and information. So how could you fail to be high-performance today with access to all those gadgets and numbers?

Does having all this equipment automatically qualify you as high-performance? No. Can you be high-performance without this stuff? Yes. Don’t get me wrong. Of course, it is awesome to have access to these tools, high-level facilities, the latest treadmills, running tracks, properly maintained courts and fields, and so forth. But not having it is not a barrier to high performance and excelling in competition.

Are the latest greatest, biggest, and brightest new types of equipment and facilities a prerequisite of high performance?

High performance is about much more than the name and facilities and equipment. It is not merely about capturing data. As many have said before me, collecting data has no value unless you utilize it properly. Are you monitoring athletes’ progress to gauge how your program is working for them, or to adjust future training practices? Spreadsheets, folders, and filing cabinets full of numbers are useless unless they impact your coaching.

Why is it so hard to understand that data without context is just a collection of random numbers.

— Vern Gambetta (@coachgambetta) September 11, 2015

What, then, is a real high-performance environment? To me, it consists of three simple, yet major facets: people, philosophies, and culture.

People

People are, or should be, your greatest commodity, your greatest resource in a high-performance environment. Talented, driven, inquisitive and ambitious people are essential You should never lose sight of the fact that people are at the center of everything when it comes to high performance.

Nice amenities do not cultivate talent … hardship does. – Brett Bartholomew

People use facilities as an excuse when in reality it is a failure of creativity. – Dan Pfaff

Learned, experienced, and forward-thinking coaches. Talented athletes with the right blend of innate physical gifts and psychological makeup: the right character, openness to coaching, discipline, and willingness to work hard. Support staff with the skills and knowledge to augment the training process, enhance the delivery of programs to athletes, and complement the coach–athlete relationship. All these people are far more important than equipment and facilities. World-class coaches working with top athletes can produce world-class performances with only basic equipment and facilities. The reverse does not necessarily hold true. Producing a high-performance environment with elite facilities but without world-class people is virtually impossible.

Vern Gambetta

Philosophy

While you must attract, recruit, and hire elite performers in all areas of your organization, that is only the start. Once you have the right people in the right positions, you need to educate them, develop them, and allow them to grow. This must be a basic tenet of your overarching philosophy.

Many coaches have a very large toolbox but cannot decide what to do because they don’t have a philosophy. – Dan Pfaff

Dan Pfaff has 40 years’ experience at the sharp end of sport, including helping Olympic long jump champion Greg Rutherford complete a clean sweep of major titles by winning the World Championships in Beijing in August (Fabrice Lapierre, also coached by Dan, took silver).

High-performance environments produce high-performance results.

Working out of Phoenix, Arizona-based Altis, Dan believes successful coaches require a governing philosophy. How can you generate logical, sensible, and effective programs and adapt them to the chaotic environments of elite sport and human physiology and psychology without a defining philosophy?

Dan recently summed up his philosophy: “Training should be enjoyable, educational, and mechanically efficient.” All coaches need a similar guiding philosophy. They should be able to define it in relatively simple terms, clearly and precisely.

In an interview, UK-based sports scientist and strength and conditioning specialist John Kiely also advocated the benefits and necessity of a coaching philosophy underpinning everything you do: “Your background philosophy steers all training designs and decisions: it should be a fusion of all your experiences and learning. If you want it to be robust, you need to invest time and energy; you need to evolve it.”

You get pretty consistent messages coming out of Phoenix (though the guys at Altis are not afraid to disagree with each other). Stuart McMillan also champions the need for a coaching philosophy in his excellent series of articles, “A Coaches’ Guide to Strength Development.” I strongly recommend the entire series.

“Good coaches are better able to learn from history—because they have a philosophy,” he says, and adds that “a philosophy protects from the comings and goings of the various trends that permeate the profession. Good coaches maintain a core set of principles—and are far less influenced by the current trends of the day.”

Stuart records his philosophy annually, restricting himself to a single side of paper. Being that exact and precise allows him to dial in on what is really important. Stuart identified his major principles as

  1. Mastery of the Basics
  2. The Planning Trap
  3. Micro dictates Macro

If one line sums up mastery of the basics, it is this—consistent application of the fundamentals. Only through applying consistent stimuli and analyzing the results can you make more confident predictions of how athletes will respond and adapt to current and future training.

Emotional attachment to a painstakingly prepared training program is what Stuart terms the planning trap. Coaches often write these detailed plans weeks and months ahead of being carried out. Devoting so much time and energy to constructing an intricate plan makes it difficult for the emotionally attached coach to deviate in the midst of delivering it, according to the physical and emotional state of athletes and how they are responding.

McMillan’s micro-organization has certain repeating fixtures throughout each cycle. For example, Monday is potentiation day, followed by acceleration day on Tuesday. There is little variation in the program in terms of structure and loading in relative terms. So in this way the micro dictates the macro.

Altis, therefore, is the very definition of a high-performance environment, with their athletes picking up five medals at the World Championships in August. Hopefully, these examples highlighting the emphasis they put on creating a guiding philosophy show how vitally important it is to operate as a high-performance coach within a high-performance environment.

Culture

The remaining vital facet in operating a truly high-performance program is culture. Culture encapsulates the ethos, values, principles, and beliefs of the people and the environment as a whole. Culture can be a powerful driver in your organization by instilling a subconscious driver of desirable behavior among everyone involved in the program.

Build a program and a culture that is built on positive expectation and accountability. – Chidi Enyia, sprints coach, Altis.

Rugby fans are fully aware of the culture of the All Blacks, the New Zealand national rugby team with probably the best all-time winning percentage of any team, a staggering 78%!. That percentage has climbed to 84% since the sport went professional. Part of the reason a team from such a small country (population 4 million compared to 50+ million in England) can be so dominant in the Rugby Union is its culture.

View image | gettyimages.com

All Blacks Captain Richie McCaw and Coach Graham Henry celebrate winning the 2011 World Cup. Culture plays a critical role in their unparalleled success.

For a sports team littered with superstars, there is a humility, dedication to hard work and doing what needs to be done. “Ego has to be left at the door; there is a rigidly enforced ‘no d—head policy’ in the squad, and every player takes turns in sweeping the changing room clean after each game,” says assistant coach Gilbert Enoka. Players themselves—not just the coaches—enforce standards. Players who transgress are answerable to their teammates.

The All Black mantra is “leave the jersey in a better place.” There is strict accountability and responsibility. The team, the jersey, and the role models they are required to be stand far above and beyond the needs or wants of the individual. This is an exceptional culture at work.

Culture drives Habits
Habits drive Behavior
Behavior drives Results!
– Alan Stein

Working in an established high-performance culture is one thing, but what about developing your own culture? Brett Bartholomew often extols the importance of creating a culture. In this article, he discusses his views on nurturing the right culture. In the gym and in training, athletes must move with a “violent grace.” He links the explosive intent of a squat or Olympic lift to a sprinter exploding out of the blocks or a throwing athlete launching their chosen implement to their training—in every case, bringing a focused intent to the work they are doing.

Brett remarks that there are many painters but few artists in coaching. Many coaches have all the paintbrushes and color palettes but cannot paint a picture. Starting the session with the “why”— the desired outcomes of the session and their relevance—brings the painting to life for the athlete. This idea is reinforced at the end of the session by helping the athlete to identify and understand what just took place.

This ties in neatly with Dan Pfaff’s coaching philosophy and the overall philosophy of athlete education at Altis. Altis proves that high performance is not about equipment and facilities. They utilize a University track and rent the strength and conditioning suite. Altis coaches expect athletes to “become PhDs in their sport.”

This approach can be summed up by Altis founder John Godina: “My only hope is that we can continue to be able to help everybody that could possibly want help from us; it is a good problem to have when your biggest concern is being able to keep up with the demand. I work hard to make sure our coaches and administrative team have everything inline for what they need, so they feel like they are pursuing what they love to do the best way possible. If we take care of our people, then I know that the athletes will always have a great place to be.”

Altis provides graphic evidence that people, philosophy, and culture are the key pillars to a high-performance environment. These three elements are intertwined, difficult to separate, and there is a great deal of overlap. How much does one drive the others? It is a bit of a chicken and the egg situation. Good people with strong, enlightened and efficient philosophies drive a positive and effective culture but each pillar reinforces and develops the other.

Sports Timing System

A Buyer’s Guide to Sports Timing for Speed

Buyer's Guide / ByChristopher Glaeser

 

Sports Timing System

Measuring how fast an athlete can go from point A to point B is a vital part of evaluating how training programs are performing. Many different options exist with sports timing, and we review the key players in speed testing and training here in this article.

Buying a timing system means you value objective feedback and want to see the cause and effect to working with athletes. It doesn’t matter if you are a weight-training-based coach, a team coach, a talent identification professional, or a technique guru—measuring speed matters. Timing systems can’t assess every movement, and they are not perfect with validity of speed since many sports have small idiosyncratic parts that make them different than track and field. On the other hand, linear speed is still a major factor as to whether athletes succeed or not. For instance, while it’s fine for Tom Brady to run 5.2 seconds at the NFL Combine, no receiver or defensive back will ever be drafted with that type of general speed.

When making the decision to invest in timing systems, you should determine how often you plan to actually test speed. This is highly related to the level of athlete you are working with, as well as the sport. Surprisingly, some coaches spend enormous amounts of money on equipment that measures everything else besides the most coveted quality in sport—athlete speed—and wonder why they seem to have inconsistent results year after year. If you are focusing on conditioning and strength training and only test speed once a year, it may make sense to leave timing systems alone and simply use a chronometer video product like Dartfish or Kinovea. However, if you are trying to improve speed, in any fashion, testing it frequently requires a system that can time quickly and accurately.

Another factor to think about is testing versus training, as some products are not great for measuring a lot of athletes quickly and some are horrible for daily use with athletes. Some of the systems available can do a combine or testing day with large groups of athletes because they use timing gates and RFID sensors to organize who is actually running, but some, like the open source products, are more appropriate for research settings. Remember that the Olympics don’t use any sports testing timing systems at all; they still use high-speed camera-based options and sometimes manually capture an athlete’s time from a photo finish. Sport timing systems are about convenience, while track timing systems are about competition timing and not day-to-day operational testing.

How Timing Systems Work

The majority of timing systems still use technology that is decades old and rely on infrared beams with timing gates. A timing gate is simply a pair of tripods placed at specified distances that relay data to a hub or collection device for display or data collection. The assumption with timing gates is that, if the beam breaks for a fraction of a second, it means an athlete has passed that exact distance at that moment in time. Unfortunately, using a beam isn’t perfect for all conditions because a running body may have arms and legs in front of the center of mass, and those few inches will trigger the beam early, thus resulting in some very small accuracy issues. Some products use double beam systems to ensure that no false (read, faster) measurements are collected, and many of the larger systems have tall tripods so nearly the entire body is measured.

Custom Electronic Timing System
Image 1: The older and more aggressive brother of sport is war; meaning that many of the technologies for athletes trickle down from the military. The speed timing system pictured here was repurposed from security systems that trigger lethal force when an intruder walks by.

 

Nearly every timing system is reliable; but again, as with any technology expect them to fail, sometimes at the worst time imaginable. We always suggest having a video camera and mini cones as backup if the testing is important, and coaches should record video of athletes anyway. Times are very important, but how you get to point B from point A is also just as valuable.

Challenges With Measuring Speed in Research and Training

Measuring speed isn’t as simple as setting up some cones and using a stopwatch. While the use of hand times is good for some situations like conditioning and long sprints, electronic timing is instrumental for seeing true change in athletic speed. The core challenge with speed testing is actually deciding on the type of protocol to use, since reliable speed and valid true measures of speed are difficult to discern.

The best step in testing speed is to determine if you are testing first movement, off a reaction stimulus, or first foot fall in the sport of track and field. A video will be able to detect when an athlete moves, but block sensors know when force is being produced. A contact mat can determine when the first step is made, but it doesn’t equate a reaction to a gun. Finally, reaction time is just a summary of when an athlete is triggered to respond, and has no connection to the movement strategy afterwards, as an athlete can stumble out and have a poor start with an amazing reaction time. As you can see, how you decide to test speed requires a lot of thinking about details, and details matter with short periods of time that mean everything in sport.

Swift Speed Light
Image 2: Competition increases arousal and output, so many coaches want timing to be done at the same time. Combines usually time athletes individually, so space is not a premium during testing, but it is during training.

 

Research on speed testing is sometimes brilliant and sometimes a scientific embarrassment that makes coaches cringe. The issue with many sport science research studies is that the timing protocol may be different based on the construction of the experiment or the access to equipment and facilities. A simple 10- or 20-meter sprint can be radically different when a timing gate is used and an athlete is rolling into it a meter back than when an athlete uses a touchpad to initiate the timing process from a stationary three-point start instead of a lean.

We also have the issue with some programs using a manual trigger to see first movement; all it takes is a middle-aged volunteer deciding to take a day off from coffee to taint the data. The starting process for testing is potentially the most at-risk point of data integrity failure. For years, athletes have found ways to inflate their times or performances to get better numbers, even it means their training process could be impacted.

The priority in testing for speed is to accept that interchangeability of times or performances between multiple programs or research is not likely possible, due to all of the variables involved. This is fine for personal data comparison or to tease out changes in research, but it does create problems in the way interventions are weighed. The need for comparing populations besides subject descriptions in studies relies on the quality of data, and some studies show such poor validity of actual speed for 10-meter sprints that we have to take the findings with a grain of salt.

Absolute abilities need to be compared to similar populations so we can decide if the value of implementing the information from the research is worth it. Several times in both research and coaching records the context for the way the data was collected makes a strong conjecture for what works or is not very difficult. When timing on your own, make sure the procedure is very carefully implemented to ensure that it’s repeatable each sample period or the analysis becomes highly suspect.

The Challenges of Measuring Agility With Timing Systems

Change of direction (agility) with athletes is a bit of a gray area since even linear speed testing has limits to its carryover in games. Testing or timing “lateral” speed is second tier when it comes to performance evaluation, due to the limitations of the equipment and context of the measurement. Agility testing still has value though, as global ability to change direction has some merit with athlete development, but the priorities should focus more on the capacity to eccentrically handle the forces and be exposed to realistic environments.

Some of the systems, like Fusion Sport, provide lights to help add in a component of reaction to the agility assessment equation. Choreographed agility tests are valid ways to estimate general agility skills, but they don’t provide enough information to determine who will be the best on the field. Like linear speed testing, poor scores are viable ways to see gross problems, but fast times could mean the athlete is just practicing to the test.

Getting better at taking a test is not the same as being smarter or knowing the material. Several combine and training facilities do an excellent job at getting better on tests, but don’t help the athlete get better on the field. This is perfectly acceptable, though, as the business of sport encourages preparing for general athletic tests, so criticisms on preparing an athlete for agility tests by repeated rehearsals is a moot point.

Freelap Tx Junior Pro Transmitter
Image 3: The strength of small timing sensors, like the Freelap Tx Junior Pro, is that they don’t create the visual debris that a forest of tripods can create.

 

Since most of the timing systems are designed for linear speed testing, timing gates that are large and bulky provide poor simulations to game requirements. Visually seeing a sea of tripods is not natural, and most of the athletes look down at cones or other equipment instead of keeping their eyes on other athletes, a ball, or field landmarks of interest. Many coaches currently use a 5-10-5 test, as well as other sensors, to evaluate how an athlete is elusive—an arguably more valid measure of agility outside of reactiveness. Do what you think you need and keep updated with the research that is constantly peeling the onion back with athletic motion.

The Top 6 Sport Timing Systems

Some open source products and other custom systems are not listed here because most coaches want to buy something that fits their needs, not make their own timing system. Coaches who say they can make their own system for less money are indeed right, but the same coaches who claim they can build their own seldom do because they are lost in a vast wasteland of other projects. Companies like Chronojump provide materials and software for timing, but, again, you have the responsibility of self-support for anything you buy in the open source world. The list provided contains the most commonly used and purchased products that have been around for years, thus ensuring that they have both a history and a good reputation.

What is not shared in each summary are prices and details like battery types and other small features. For the most part, pricing is hard to give, as many distributors will sell bundles and discount based on deals—something that is annoying to coaches who just want to know what the true cost is. We share some general information about the company on the product list, as well as how the data is collected and the unique elements of the product. Except for Freelap, most of the products are IR systems, which means they use timing gates with infrared beams. Some of the systems are used in research—in fact, nearly all of them at some point—and all of them are accurate for everyday training.

Brower Timing: The most common timing system in the U.S. is still Utah-based Brower, which has been around for decades. The system is single beam and require a lot of set-up time if preparing for multiple splits. The system is dated, meaning it requires household batteries and uses readouts that seem stuck in the 1980s, but because the product is straightforward, it keeps selling. The Ski option connects to a smartphone, but requires a transmitter link to do so. Some research used the timing system for simple experiments, but over the past year more of the studies used other options like Microgate and Swift.

Freelap: This Swiss option is perhaps the most unique system on the speed timing market. What is different about the Freelap product system is the transmitters are tiny and don’t take up valuable track real estate. The product is also the only wearable model, as a chip is required for each athlete to speed up workflow and to indicate the athlete moved past the transmitter’s magnetic cloud. One benefit we love is the ability to time multiple athletes at the same time, with the equipment taking very little time to set up. The data is sent to an Android or Apple iOS device instantly, instead of only being stored locally on the sensor.

VALD: Well known for its comprehensive suite of human measurement technologies, VALD acquired the SmartSpeed Timing Gate System from Fusion Sport. Offering the entry-level SmartSpeed Dash and the more advanced SmartSpeed Pro, both timing systems use Single Beam with Error Correction Processing (ECP) technology and are renowned for their accuracy. SmartSpeed Pro’s multi-colored lights allow for a range of reactive agility tests, while a portable jump mat accessory and additional RFID wristbands add to the wide array of testing options. The ability to wirelessly control gates and conduct drill sessions through the app ensure the systems are popular with sporting teams and high performance professionals around the world.

Microgate: This Italian company has two primary timing systems: a conventional gate system (Witty) and their Optojump system, which resembles a train track, only with hundreds of IR beams along the way. Microgate have an IMU system, but it’s not really used for timing athletes for speed. While the Witty system has no special features, it’s a high-quality design and offers promise to coaches.

Swift Performance: Swift Performance is an Australian company that provides a jump mat and enterprise timing system for research and serious teams, mainly rugby. One of their key features is a connection to an iPad, as many coaches want data to go straight to their hands instead of a laptop. Swift has a great history of working with research universities and published studies have used their equipment. One of the strengths of the Swift timing system is the Speed Start. Instead of the common button starting pad, this system uses a beam near the ground, giving it a natural feel for many athletes.

Zybek Timing System: Zybek Sports is another U.S. company, based on Boulder, Colorado. Like Brower Timing, they have other products, like training equipment, but focus on timing systems. One of their key successes is that they have been part of the NFL Combine in Indianapolis for years. They have a very extensive focus on agility measurement and have several bundles that focus on American football tests. In addition to their hardware, they help facilities assess speed better with a program called S.A.T.

Most of the companies allow for incremental purchasing, meaning you can buy a start and finish bundle and add more splits if you want. Some also provide popular packages for a small discount. Price points are highly sensitive to key details like the design of sensors, indicator lights and battery life, and relay ability to tablets and handhelds. Our suggestion is to look at the type of environment you plan to be in and whether you are training with the system consistently. If you time speed a lot, go with Freelap or the two American products. If you are doing research, go with the Italian or Australian options.

Getting Started With Sports Timing

A word of wisdom when getting started with timing systems is to practice a few times before adding speed testing to your program. Nearly every system is stable enough to provide a reliable and effective way to measure speed, but some demand more administrative duties than others. Budgeting is perhaps the No. 1 factor in selecting a timing system, but the cost is not just price; it’s also how much time and effort it takes to provide timing for your athletes. We have used nearly every system and each has its own pros and cons, but just getting a sample of how fast an athlete can sprint is invaluable. We highly recommend getting a timing system to evaluate your program.

Block Start

Moving Your Center of Mass Faster: The Importance of the 0 Step

Blog| ByChris Korfist

Block Start

When running a business which deals with high school athletes, parents sometimes contact me when their child seems to lack a skill that is forcing them to fall behind their peers. Even if the child was at the top of their game at one time, they’ve fallen behind and are frustrated. To help their child succeed and achieve their goals, the parents bring in outside help.

One of the first traits the parents always mention is first step quickness. From what they’ve seen, there’s something that causes the child to be a step slow. Or the child can’t get past the opposing players as they once did.

When we plan a path to improve this, they’re often disappointed that the issue is not about being quicker. It’s about moving the body’s center of mass faster.

As I have mentioned in previous blogs, JB Morin’s research on acceleration has surfaced recently. For those who want to cut to the chase, look at Peter Weyand’s and Ken Clark’s review of Morin’s research. They conclude two things. First, horizontal force applied in a useful manner is a key determinant of speed. We will focus on this in a coming blog.

Second, there’s a speed difference in the 0 step. The 0 step is the acceleration from the block to the first step. Morin’s research showed a 0.5m/s difference between the 10.0 athlete and the 10.5 athlete. It accounted for 80% of the difference among the athletes tested.

After reading these papers, my “rabbit hole” turned into researching the 0 step. It took me months to truly understand the concept.

I had two flashes that helped me put the idea together. The first was in Austin, Texas, where I was hosting a Reflexive Performance Reset seminar. Peter Holmertz, President of 1080 motion, gave me a tour of the city and took me to notable, cutting edge facilities in Texas. We stopped at one of the best planned facilities I’ve seen called Xceleration Sports Performance Labs owned by Matt Neel. He commented, “It is great if we know all of this stuff. The trick is to communicate it with your athletes.” He had a special grid that communicated to his athletes their 0 step. It suddenly made sense to me.

My second epiphany happened during the first night of the TrackandFootballConsortium IV. I spoke before Stuart McMillan of ALTIS and talked about the importance of the 0 step. In his great presentation, he talked about five things a coach can do better. One of his topics was the 0 step.

However, he had a much better term than 0 step. He called it projection. This is a far better word to use to communicate to my athletes what we are striving for when coming out of the blocks.

When explaining the 0 step, talk to your athletes about projection. Share on X

With these new guiding principles, I went to work on my project to figure all of this out. I wanted to see what it would take to get my athletes to project their body further “coming out of the blocks.”

Using my 1080 Sprint to collect data, I wanted to see how and why some were better than others at this. I wanted to use the MySprint app as well, but Chicago had some bad weather that made running outside difficult. (I don’t know which hinders runners more, 0-degree temps, 8” of snow, or that to save money, the village does a poor job of plowing and salting.)

In conjunction with that, I stole Matt Neel’s idea of measuring the athlete’s hip distance when their foot hits the ground. Currently, I’ve measured about 25 athletes, with more to come. I picked four of them to show different aspects of what I’ve found. I am looking at N/kg, w/kg and velocity at 0.5m, and their projection distance. The first three numbers were taken from the Sprint 1080 with 1KG of resistance.

Time to Peak Velocity
Image 1. Gillian weighs 49 kg, her N/kg is 0.77, her w/kg is 1.85, and her peak velocity is 2.40 m/s at 0.5m.

Athlete Projection Score
Image 2. Gillian has the farthest projection score of 3.5 ft.

Time to Peak Velocity
Image 3. Mike plays football in the CFL. His scores are 0.58 N/kg in force, 1.5 w/kg and a peak velocity of 2.79 m/s at 0.5m.

Athlete Projection Gate
Image 4. Mike also has a 3.5 ft. mark in the projection gate.

Time to Peak Velocity
Image 5. Isiah is an All-state 400/800m runner. His scores are 0.66 N/kg, 2.05 w/kg and a peak velocity of 3.07.

Sprint Start Projection
Image 6. Isiah’s projection is 2 ft.

Time to Peak Velocity
Image 7. Athlete 4 is a sophomore football player. His force is 0.49 N/kg, his power is 0.91, and his peak velocity at 0.5 m is 2.0 m/s.

Sprint Start Projection
Image 8. Athlete 4’s projection is 1.5 feet.

From these examples and others that I have stored on my 1080 chart, we see that force is an important factor in getting the body out. I like to use force/body weight because it puts all athletes on an equal playing field. Also, from all of the data I’ve collected over the last 18 months, N/kg and w/kg seem to be the determining factors in acceleration.

Force gets the body out of the blocks. N/kg and w/kg help determine acceleration. Share on X

Isiah doesn’t quite fit into the scheme. While having the best time and power output, his N/kg is not the best. He is an athlete who gets his feet down quickly, pushes quickly, and generates power quickly. All athletes are different and get there the way they know best. So, where do we go from here? Stay tuned. More to come.

Kettle Bell

What We Know About Training Athletes with Kettlebells

Blog| ByKen Jakalski

Kettle Bell

I love training my athletes with kettlebells. Have I been influenced by folks like Pavel Tsatsouline and Dan John? Yes. I also understand that the hype over the kettlebell results from its re-introduction to American coaches as some secret Russian special forces training device when, as David Landau points out, the kettles are really “tied to the Circus, Vaudeville, and good old Show Biz.”

Kettle Bells

Landau refers to the kettlebells as “faux entertainment, a crude weight implement that has many shortcomings.” So how do we explain the excitement over the kettle comeback? Landau believes it’s a belief in the apparent superiority of Russian training systems. He refers to Rocky IV as evidence. In the movie, the Russian boxer Ivan Drago is the product of high-tech training and sophisticated diagnostic equipment. He’s not like ole Rocky training in a barn and doing core twists with an oxen yoke across his shoulders.

It was Rick Bruner who clarified the reality of Eastern Bloc training in his book, Soviet Training and Recovery Methods. “In real life,” he says, “the scenario is just the opposite. The Soviets are training in barns and basements, and the equipment is forged from old railroad car axles. They also run in the snow. Most Soviet athletes have never seen a computer, let alone a computerized Cybex machine, a Lifecycle, or a Stairmaster.”

Landau confirms this, recounting how Americans visiting Russia in the 1980s found athletes using crude training implements. When asked where they were getting their training information, they “pointed to an old stack of Weider Muscle Magazines.” In addition to barbells and isometric racks, there were “a few odd weights that may have been kettlebells.”

So the kettlebell we know today is not a modern version of scientifically researched strength training equipment. It appears to be, as Landau concludes, a “rather crude weight implement that has many shortcomings.” Weightlifters from those early days admitted that the kettlebell had limitations and shortcomings. As Alan Calvert said in 1911: “The man who buys only a kettlebell and thinks that he is going to be able to train all the muscles in his body to the same degree of development is going to be very badly fooled.”

Why I Use Kettlebells With My Athletes

If this is the case, why are these big balls with handles a staple of my program as well as so many others? Proponents of kettlebell training—and there are many–raise some valid points. For example, John Powers notes that “one advantage of kettlebells over dumbbells, barbells, and machines is the dynamic, ballistic nature of the moves.”

His point is that athletes can use kettles to lift, push, pull, and reach. Their most significant benefit is that the “demand for greater inter and intramuscular coordination and kinesthetic awareness remains stable during the exercise.” More muscles and joints are involved in each kettlebell movement, and “the core, hips, and other muscles involved in stabilizing the body are constantly working.”

Kettlebell movements demand muscular coordination and kinesthetic awareness. Share on X

Dan John has often commented that “if all I do is teach a proper swing and encourage some form of deadlift, I know I will have an impact. The kettlebell swing remains my go-to for both fat burning and building athletes.”

I use kettles as a transition to my primary lifts: the trap bar deadlift and such variations as single leg deadlifts, single leg cleans, and step-ups.


Video 1. The athlete performs a single leg, split leg deadlift with two kettlebells.


Video 2. A deadlift with a trap bar is demonstrated here. I also have an open back trap Superbar that allows athletes to extend the back leg during these variations. I call it a half-trap.

Kettles serve as a good lead-in to these lifts. I specifically like the goblet squat and the kettle swing.


Video 3. This athlete demonstrates the goblet squat while holding one kettlebell with both arms.


Video 4. This goblet squat is performed with two kettlebells.


Video 5. The athlete demonstrates the classic kettlebell swing.


Video 6. The video shows the athlete performing a reverse kettlebell swing.

An article entitled “Kettlebell Lifting as an Effective Means of Physical Education” appeared in the 1984 Russian Weightlifting Yearbook. The article concluded that kettlebell lifts were suitable as a means of education for a wide range of sports:

“The appropriateness of kettlebell lifting is associated with the possibility of individual workouts, the technical simplicity of the exercises, the ease of obtaining, and the possibility of training and competing with people of different ages. Kettlebell lifting develops basic physical qualities and increases physical work capacity. All of these lead one to consider kettlebell lifting an effective means of physical education.”

Even though a considerable number of athletes are discovering and defend their use, is the kettle a magic orb that improves all aspects of physical performance? Is kettlebell training any better than training with dumbbells or barbells? Might the current hype surrounding kettles be nothing more than an example of what the great Dutch Speed Coach Henk Kraaijenhof used to describe as “old wine in new bottles”?

I like kettles because my athletes like using them, not because I view kettles as better than other strength training protocols. I also understand why kettles are just one of many worthwhile approaches coaches can take for strength training. I think Mel Siff said it best, “Kettlebell training can be great, it can be fun, so can dumbbell training, so can barbell training, so can many other forms of strength training. Only don’t let one’s love for anything turn you into a fanatic who fails to see the merits in other walks of life.”

Protein Nutrition Athlete

What Every Athlete Should Know About Protein

Blog| ByCraig Pickering

Protein Nutrition Athlete

If there’s one nutrient that’s most strongly linked to athletic performance, it’s protein. There are so many myths, or bro-science, regarding protein requirements that it’s easy to be misled and confused. Further complicating the issue, supplement companies aggressively target athletes with marketing about the need for protein. In this article, I’ll look at what the research suggests is the best practice for athletes when it comes to protein intake and timing.

Protein Explained

Before we dig into the sports-specific research, I’ll quickly explain what protein is. There are three major macronutrients: carbohydrates and fat, which our bodies mainly use as fuel, and protein, which we primarily use for growth and repair (in certain situations it can also be used as a fuel). Each gram of protein provides about four kilocalories (kcal) of energy–the same as carbohydrates.

Proteins are long chains of amino acids joined together by peptide bonds. Some of these amino acids cannot be produced by the body, so we need to get them from our diet. These are called essential amino acids, of which there are nine. Six amino acids are termed conditionally essential; while the body can produce these from other nutrients, this ability can be significantly reduced during periods of stress. Finally, there are five amino acids which the body can produce itself; these are called dispensable amino acids.

Table 1. There are nine essential amino acids we can only get from food. Our bodies can produce six of these from other nutrients unless we are under stress. The body can generate the five dispensable amino acids by itself.
Type Amino Acid
Essential Amino Acids Phenylalanine, Valine, Threonine, Histidine, Lysine, Methionine, Tryptophan, Leucine, Isoleucine
Conditionally Essential Amino Acids Proline, Glutamine, Glycine, Arginine, Cysteine, Tyrosine
Dispensable Amino Acids Alanine, Serine, Asparagine, Aspartic Acid, Glutamic Acid

Whenever we eat protein in whole forms, such as food and protein powder, we are consuming a mix of these amino acids. Within the essential amino acids, there is a sub-group called branched-chain amino acids (BCAA), which again are aggressively marketed by nutrition companies. These BCAAs are leucine, isoleucine, and valine, and they have important roles. Ideally, about 35% of our protein should be in the form of BCAAs. Fortunately, that’s the rough ratio of BCAAs found in most food products.

Protein has several roles in the human body, many of which are important to athletes, and is abundant in our bodies. There are structural proteins, such as those found in muscle and skin, and functional proteins, such as enzymes, growth factors, and parts of the immune system. When we exercise, we cause damage to our muscles. As our muscles are largely comprised of proteins, we need to repair and replace the damaged proteins; this can also lead to hypertrophy. Amino acids also play a role in a variety of different metabolic pathways, support immune function, and can be used as energy.

Protein Requirements for Athletes

It appears logical that athletes, who are engaged in a greater amount of exercise and will suffer from greater protein damage and turnover, will need more than a “normal” human. The typical recommendation for non-athletes is around 0.8g of protein per kilogram of bodyweight per day. Individuals who consume animal products regularly will likely get sufficient amounts through their diets.

How Much Protein Do Athletes Need?

But how much do athletes need? Several research papers have attempted to answer this question, and one of the key researchers in this field is Professor Stuart Phillips from McMaster University. In a paper from 2006, Phillips explained that many studies support the notion that athletes of all kinds have higher protein requirements than sedentary individuals.

In a 1992 paper, Lemon and colleagues reported that, in a group of twelve resistance training males, protein requirements were 1.6-1.7g per kilogram of body weight per day–double the recommended daily allowance (RDA). There appeared to be no benefit regarding muscle strength or size with higher protein intake (the researchers tested 2.6g/kg/BW). These results were mirrored by Tarnopolsky and colleagues in another 1992 paper finding that 1.76g/kg/BW of protein per day was optimal for strength-trained athletes.

It’s not just strength and power athletes who require increased protein, however, with research suggesting that amounts above the RDA are also important for endurance athletes. Increased protein intake by athletes also supports immune function and guards against overtraining. Clearly, it’s important for performance athletes to have higher intakes of protein than the RDA.

Protein Requirements for Weight and Fat Loss

From time to time, athletes are also interested in losing weight and fat. In non-weight category sports, athletes usually want to decrease fat mass while maintaining or gaining muscle mass to improve the crucial power to weight ratio. It’s important to note that the optimal amount of body fat is highly individual, depending on a person’s unique makeup and sporting demands.

In sprinting, for example, during the general preparation period, athletes need to consume sufficient calories to support training adaptations. However, before the competition periods, sprinters typically aim to “lean out,” and lose a bit of fat while maintaining muscle strength and power. In weight category sports, athletes tend to live day to day at weights well above their category and then cut their weight before a competition. Again, maintaining lean body mass is important; if an Olympic weightlifter loses strength before competition, they likely won’t perform their best. Higher than normal protein intakes give them an advantage.

Several studies of non-athletes suggest that higher protein intake helps with fat loss by increasing thermogenesis as protein requires greater energy to metabolize than required by fats and carbohydrates. Protein also improves diet adherence by increasing satiety, keeping you feeling full longer.

While restricting calories, increased protein helps athletes keep their hard won muscle mass. Share on X

During periods of caloric restriction, increased protein intakes appear to successfully maintain lean mass levels, allowing athletes to keep their hard won muscle mass. A 2004 paper, authored by Stuart Phillips published in Sports Medicine, suggested that athletes undertaking a calorie restricted diet may need to consume as high as 3g/kg/BW per day to offset the loss of lean body mass.

Can Athletes Consume Too Much Protein?
Is there such a thing as too much protein? We often hear too much protein can damage the kidneys, but research indicates that protein intakes of up to 2.8g/kg/BW per day are safe for healthy individuals with no previous history of kidney issues. Higher amounts may also be safe, but it isn’t clear due to a lack of data. In an 80kg athlete, this would equal close to 900 calories of protein (224g of protein), the equivalent to 800g of chicken breast.

When Athletes Should Consume Protein

We’ve established that protein is important for athletes and that they almost certainly need intakes higher than recommended for the general population. The next question is: when should athletes consume their protein? Research indicates the BCAAs, especially leucine, activate a number of key enzymes involved in muscle hypertrophy and repair. Based on this, it seems obvious that we want to consume at least some protein around the time of our training session to allow this activation to occur.

After resistance training, combining protein and carbohydrates increases muscle protein synthesis when compared to carbohydrate intake alone. We can enhance this increase by adding leucine to the protein-carbohydrate drink. However, it’s worth pointing out that the subjects in the research study were in the fasted state–they hadn’t eaten since the previous evening. This is a common practice in research because it removes the effect of a pre-training meal; individuals might consume different foods which might alter what the researchers are measuring. This is a great example of how science doesn’t always carry over to practice, unless you’re performing resistance training in a fasted state.

Consuming protein before training may be more important than after training. Share on X

In fact, some research suggests that consuming protein before training is more important than post-training. Again, this is logical, given that it takes time for the protein to digest and be transported to the muscles. Based on these findings, it’s sensible to suggest that athletes consume protein both before and after training.

Placing this into a real world context, if you have a meal before training, ensure it contains protein. After training, have another meal with protein or a protein supplement (possibly with added leucine). It appears that 20g of protein post-training is the minimal amount. In a really good review on whether or not the post-training anabolic window exists, the authors suggested that protein intakes of 20-40g both before (one to two hours pre-) and after training were optimal for building muscle.

There’s considerable scientific debate about how often athletes should consume protein. There is evidence that the “muscle full” effect exists, where protein intake above a certain level does not further enhance muscle protein synthesis. For example, this study found that 20g was sufficient to maximally stimulate muscle protein synthesis, and any intake above this amount led to an increase in amino acid oxidation for energy. An earlier study had similar findings, stating the optimal protein intake was 20g every three hours while greater intakes potentially reduced muscle protein synthesis.

Ingesting more than the optimal amount of protein may reduce muscle protein synthesis. Share on X

We can conclude that we want fairly regular intakes of protein spread throughout the day, as opposed to one large serving. For an individual training in the morning, this could mean having protein at breakfast (this is the meal with typically the lowest protein intake), followed by a post-training protein shake. The athlete should have protein at lunch and dinner and possibly an additional protein snack between lunch and dinner or before bed, depending upon meal times. Three to four hours between protein intakes is considered “ideal.”

Protein Sources for Athletes

We can find abundant protein in our diets, provided we eat the correct foods. Animal products, especially meat, typically have the highest protein. And these proteins are complete proteins, containing all the essential amino acids. Protein shakes, which often consist of whey or casein, and amino acid supplements are also protein sources. These have the advantage of being convenient but are typically devoid of other nutrients. One way around this is to use protein powders in a smoothie. I tend to mix mine with frozen berries, spinach, and almond or coconut milk for additional nutrients.

For vegans, protein sources can be harder to come by, and vegan proteins are often incomplete proteins. Vegan athletes must combine numerous protein sources to ensure they meet their protein needs. This isn’t to say that vegans can get sufficient protein, just that it may require additional planning.

Conclusion

We’ve seen that the RDA for protein is insufficient for athletes in all sports. Intakes of about 1.5g/kg/BW are likely optimal for endurance training athletes, with slightly higher amounts–1.7g/kg/BW–ideal for resistance training athletes.

Higher protein intakes may be ideal at certain times, for example during a low-calorie diet. Eating protein throughout the day, including pre- and post-training, is better than a single large protein intake. As such, at least 20g of protein should be present at all meals three to five times a day, ideally with three to four hours between each meal. Finally, these amounts of protein are safe for healthy athletes, contrary to popular myths.

EDGE10 Athlete Management System

A Buyer’s Guide for Athlete Management System Software

Buyer's Guide / ByChristopher Glaeser

EDGE10 Athlete Management System

The popularity of earlier articles on sports training and rehabilitation equipment and technology was a natural sign that we should provide information on Athlete Management Systems. Currently, about a dozen systems exist on the market, but we narrowed it down to the top 10 based on market usage and the projected outlook of the company.

Several vendors have come and gone, meaning they started out with gusto but are now struggling to get adoption. New companies are sprouting up every year; some make it and some don’t. While the market is evolving quickly, we share timeless advice in this review on how to go about selecting the right system for your needs.

What Is an Athlete Management System?

If you ask different coaches and sports medicine professionals what an Athlete Management System (AMS) is, you will likely get a few different answers, but everyone will know it’s software. AMS products range from very inexpensive cloud software to major custom investments that cost tens of thousands of dollars.

While it’s hard to define what an AMS is, everyone in the sports technology space will likely agree it’s a platform to update important athlete status information for organizations and teams. The details of what the platform can do beyond storing simple data like biographical information or a limited medical record will vary, but those differences are the reason we put this guide together.

ISTA Conference
Image 1: At the International Sports Technology Conference, the Boston Red Sox data management team discussed how organization collects and shares information. They are currently Kinduct users, utilizing the software as a central hub for communication.

A good case for an AMS to simply be a central organization solution for teams was accurate in the early 2000s, but today the expectations are much higher. Professional teams, colleges, and leading training centers demand more than a portal to update athlete data; users want to have analysis and integration with devices and other software programs. A perfect definition isn’t possible now, but the expectations are that the AMS market should do more than just recordkeeping.

Some software products are mostly training or workout design tools, while others are excellent dashboard solutions but can’t do much beyond visualization data. A few solutions do a great job managing different data sets from devices, while others can’t import anything beyond their own hardware. With such a range of differences and variations of roles, AMS shopping is very difficult to do without knowing what is possible with athlete’s software and what may be important in the future.

Important Technology Terminology for Coaches and Sports Medicine Staff

If they don’t know the key terminology specific to software, professionals can get quickly lost in a sea of three-letter acronyms that sound exciting at a sales meeting but are likely just buzz words. The backroom staff is growing larger and larger, so organizations now have more support personnel than players. With different roles and needs, one software program will have a lot of work to do to satisfy the many unique requirements that staff have in sport. We have touched on many of the terms below, but now we are going to define them and explain why they are important for every staff member.

AMS software has to satisfy the many unique requirements of different sport staff members. Share on X

Metric: A single measurement is called a metric, and usually its value and how often it is calculated separates a metric from a random measure. Metrics can be nearly anything, ranging from morning Heart Rate Variability scores to practice workloads. Metrics are predominantly distilled to single numbers and displayed, but they are also used in calculations with other metrics to tell a more contextual story.

KPI: Many measurements matter in sport, but Key Performance Indicators (KPI) are usually high-value metrics because they connect to success more than other measurements. Teams and performance experts typically use KPIs to guide them in training and to see a cause and effect with design training and competition strategies.

Dashboards: The most common feature of an AMS is the athlete or team dashboard, a one-screen or one-page summary of the current status of the player(s). Dashboards are simple at-a-glance summaries of athletes with data that changes rapidly, and those measurements are usually KPIs. Dashboards are visually stunning to coaches and medical staff and are huge sales tools to encourage adoption, but most of a team’s needs are in other areas like workout builders and reporting.

Algorithm: The most abused buzzword in sport science is the term “algorithm,” or another way to say a calculation. A simple weight conversion formula from kilogram to pounds is technically an algorithm, but the term conjures Manhattan Project blackboards with high-level astrophysics. While you can argue that any calculation is an algorithm, the true connotation is that it’s a high-level, step-by-step, custom procedure in software to handle difficult math that is unique to the needs of the problem.

Analytics: Data is an easy way to spark up the value of what coaches are doing, and the current trend is to look at as much data as possible to see patterns or trends that go beyond the eyeball test. Advanced statistical analysis is necessary at times to show true importance or validity of a belief, but for the most part the best data is actionable, it’s simple and it’s straightforward. Some AMS programs provide analytic engines, or software to help break down data into meaningful outputs, but many AMS products work with third-party products.

API: An API is simply a way for external developers to interact with the website or application. Coaches, especially those that use wearables or monitoring tools, demand an API from the device companies to extract information and aggregate it to a central AMS product. Constantly exporting files and uploading them is time-consuming and monkey work, so team staff has asked device companies to provide an API for AMS companies. Some data providers are not allowing for an API as they want their own platform to sell, and they are “cutting off the pipe.” This is the reason costs are high and speed of use is low.

EMR or HER: The first AMS product was likely the paper or analog medical health record that eventually evolved into the modern electronic medical record. There isn’t much of a requirement to be considered an EMR from a technology standpoint, just being current with software security. Medical record software requires HIPAA compliance and that’s easy for any vendor to do. Most EMR products are shortened medical histories of dates of service, medications, and past medical imaging. Because all EMRs are top-down—meaning doctors summarizing their findings—sports teams are using more bottom-up approaches from athletes and their support staff and leaving EMRs to store medical imaging and prescriptions.

AMS Graph
Image 2: Monitoring athletes is the No. 1 priority of most AMS products. This an example of a dashboard with KPI lists from the Canadian company, AthleteMonitoring.com.

The above terms are most of what constitutes an AMS product, and they are enough to help you select the right software package. Some systems don’t touch medical information, and some are mainly medical in nature, especially the early AMS products from the U.K. Managing data centrally is not a big challenge; the real challenge is making it user-friendly for everyone, while keeping it powerful enough to do what teams need.

Essential Components and Functionalities in AMS Software

Most of the core features of AMS products involve communication between parties and the ability to share information when communication isn’t possible. Beyond those two needs, the market gets into a gray area of when a product becomes something else. For example, designing workouts and storing them is the most effective way to reduce injuries, but for the most part, training loads from GPS products are one of the few shared data sets.

Team coaches or position coaches rarely see workouts in the weight room, resulting in a limited view of the process. Add into the equation the fact that athletes often hire private trainers even during the season; the AMS system usually has only a partial snapshot of what is truly going on.

Common AMS Features

A Calendar Planner allows for everyone to view what and where things need to be, and organizes large groups effectively. Some conflicting information exists on how athletes should share their private calendar, but this is resolving as the market evolves.

Every system should have a standard or customized Dashboard so staff can act quickly and effectively.

Push or SMS Notifications are a staple for teams wanting to organize communication beyond texting from a smartphone.

Simple Data Visualization is a midpoint, since action steps taken afterward are the full solution. Still, the right charting and graphing properly informs staff to make the right decision for the athlete.

Wellness Questionnaires are a staple with most products because they are easy for software developers to make, but on average most of them lack the user experience required to keep athletes engaged.

Session Designer tools are important, and they range from very functional strength and conditioning tools to a glorified whiteboard application that allows for the sharing of text. Typically, as you focus on monitoring, the training programs seem to fall off the hierarchy of importance.

It’s uncertain if AMS products will start to evolve and grow or break into smaller components that work with other systems instead of competing. The challenge is to service teams and sporting organization with more turnkey solutions, but the standard and feature’s demand for power only makes development slower and more difficult for companies that build AMS products.

CMP Mobile App
Image 3: The mobile experience with the athlete is arguably the most important step in successful data collection. No matter how great the analytics are on the backend, the bottlenecks are always the athletes themselves.

Several AMS companies have partnered with other similar software platforms that have unique differences to encourage collaboration and communication. Other data providers that collect physiological or sensor data have analysis software that simply can’t be replicated to be housed in an AMS product, but some metrics can be pushed to dashboards and other analysis that is more manual can still be done offline.

Top AMS Companies

We will refresh the current list of AMS providers in a year or two, as the market has been surprisingly stable since 2012. One expectation is that the list will grow and market share will likely shrink due to the space having very few ratings and vetting programs. Based on adoption rates—meaning how much client traction the AMS product has—the list below summarizes the most commonly used systems and the next review will feature more software evaluation. For now, here are the Top 10 software options.

CoachMePlus: CoachMePlus is an applied sports science platform that is changing the way coaches and athletes prepare for competition. CoachMePlus focuses on making data collection and analysis more straightforward and simpler for coaches. Its powerful software provides teams the most complete set of tools for safely preparing athletes for competition. While many other companies on this list specialize in either large teams and organizations or smaller market gyms, CoachMePlus’s versatility makes it the only platform on the market that is able to cater their platform to accommodate the size and scope of any organization. Their platform easily accommodates many different types of organizations ranging from high schools, and private training facilities, to colleges, pro teams, and the military. Their suite of tools allows coaches and athletes to work together locally or remotely on programming.

CoachMePlus provides a full platform for coaches and sport scientists with many unique and innovative features including:

  • Performance and movement testing
  • Injury tracking and management
  • Nutrition, weight, and hydration tracking
  • Athlete-coach communication & Learning Management System
    • In-app messaging
    • Custom Library (Videos, documents, etc.)
    • In-app athlete feed (can be automated)
  • Automated Program Assignment
  • Available for IOS and Android
  • Universal Data Importer
  • Over 60 device integrations

This platform gives you access to elite training software used by the highest-level strength and conditioning coaches. Using CoachMePlus all athlete performance data is captured and centralized in a comprehensive, customizable set of individualized reports, dashboards, assessments, and alerts where information is communicated to the right people at the right time.

Kinduct: This Canadian AMS option is no stranger to the team and fitness sector, and has a strong presence in all major sports, especially in North America. Kinduct’s popularity in pro sports is due to the fact it has very strong visual appeal and the ability to use data from different providers. Kinduct is active with some high schools and colleges, but they focus on pro teams and private training facilities.

AthleteMonitoring: This system has improved tremendously since our last review. While keeping a large focus on the management of workload and the ability to identify risk of injury with evidence-based metrics, the system has evolved into a complete AMS platform now used by sport academies, national sports organizations, universities, sport medicine research centers, and Olympic programs worldwide. Based in Canada like Kinduct, AthleteMonitoring is exceptionally strong in the realms of sport science, injury prevention and sports medicine / medical needs. The cost-effectiveness, versatility, simplicity, and feature set of AthleteMonitoring are the main reasons why teams and institutions love them, as the system is simple enough for the daily management of athletes’ workload, but also includes all the research and data management tools required by scientists and administrators.

SMARTABASE: Australia-based Fusion Sport is the company behind SMARTABASE, and it has a rich tradition of working with sport scientists. SMARTABASE connects seamlessly to testing products like electronic timing and jump testing, and the product can import a lot of different data types and do marvelous reporting. The adoption is strong with larger organizations, such as big-time colleges and professional teams, but the price point is not appropriate for high schools and small facilities. SMARTABASE is doing very well internationally, and they have entered surprising markets like research and military.

Metrifit: Similar to AthleteMonitoring, Metrifit is a smaller market product, with enough of a following to appear on this list. However, due to the competitiveness of the space, they are less visible in the market than Kinduct, SMARTABASE, and CoachMePlus. One of the Metrifit’s strengths is that they are very developed on the mobile side of things, and really focus on the core essentials of AMS products, namely communication and subjective athlete monitoring. Many satisfied clients, ranging from English Premier League football to college basketball, are in favor of the product doing the fundamental aspects of athlete support.

AMP: AMP is a smaller company like Metrifit, and has a nice solution for simple and fast communication between coaches and athletes. AMP was at the International Sports Technology Association Conference and should be poised to grow and evolve if they take advantage of the brain trust from the meeting. AMP is a lean solution, and is working on a way to push correspondence training programs as it caters to more Olympic sports based on their early adopters. Due to the cost of the system, some teams consider it an entry point product, but with software development in a year this can change very quickly.

BridgeAthletic: BridgeAthletic builds strength and performance software for coaches, personal trainers, and physical therapists. Founded in 2013, Bridge gained an early stronghold in collegiate athletics and is now considered a premiere training software for professional and elite athletics.

Bridge presents a flexible and easy to use programming builder, which includes several differentiating features:

  • seamlessly clone and template macro-cycles, meso/micro cycles, workouts and workout components
  • drag and drop functionality
  • individual edits ‘on the fly’ via tablet
  • proprietary % difficulty algorithm for individually adaptive weight prescription
  • volume, intensity, and load visualization for prescription analysis
  • API capabilities with Smartabase, Edge10, Kitman, Kinduct, and other data aggregators
  • Dedicated account manager with any of their annual plans

Bridge is well known for their workout builder to design your own macro, meso, and microcycles, as well as build multi-week circuit progressions across programs. Bridge’s tablet features allow you to build and deliver plans directly, without needing a computer. Lastly, they are the only training software to offer a truly dedicated account manager with any of their annual plans.

TeamBuildr: Another U.S. product, this one is getting a lot of traction in the small college setting and is thriving with high schools as well. Mainly an Excel and clipboard replacement for teams, TeamBuildr does have some limited communication tools that are sufficient enough to function, but not robust to be dependent on. TeamBuildr is a very small company, with less than five employees, and is one of the least expensive entry point products on the market next to fitness apps. The strength of TeamBuildr is that it’s simple and fast for coaches who may not have a lot of office time and need to be on the floor.

TrainHeroic: This Colorado startup is very strong on the strength and conditioning side because they place a lot of development resources into the strength-training design parts of the software. The company also has a marketplace for coaches to share their workouts like the iTunes store. Another strategic benefit is their geographical proximity to TrainingPeaks, the most successful endurance software product on the market, giving them an anchor to lean on as the competition becomes more demanding. TrainHeroic works with high schools, colleges, and some of the best pro teams. The product has some monitoring features, but its primary role is workout design and post-training analysis.

EDGE10: One surprise in the AMS space is the U.K. company, EDGE10, which survived the onslaught of new companies over the last five years. With strength in soccer, they were agile enough to grow to other sports here in the U.S., including American football. One of the best features of EDGE10 is the medical recordkeeping, and other tools like statistical analysis of other areas outside of sport science. EDGE10 has its roots in other markets outside of sports, and that may either be a strategic move to ensure revenue or a way to learn from other industries (or both).

PLT4M: Founded in 2012, PLT4M has flown under the radar while modifying and improving their product. PLT4M is the only software built exclusively for high schools, and are now one of the leaders in that market, providing their programs and software to over 700 Athletic and Physical Education departments across the U.S. What makes PLT4M unique is its mix of content and software. Offering 12 programs for every level from the novice 7th grader to the college-bound athlete, PLT4M programs are supported by 500+ demo videos. For those schools with established workouts, PLT4M also provides the ability to integrate and build unlimited programs. With both an iOS and Android app for kids and coaches, PLT4M provides improved data tracking and reporting along with streamlined organization and workout delivery. As one of the more affordable options, PLT4M provides great value for the Athletic and Physical Education Departments.

MaxOne: This is another U.S. product thriving in the high school space and gaining traction with clubs and select colleges. Labeled as the all-in-one coaching app, MaxOne delivers calendars, messaging, and training features to coaches looking to run a more efficient program in every single area. Coaches can create customizable workouts that can then be assigned to the athlete directly on their mobile device. Parents, coaches, and athletes can all stay on the same page via one-touch messaging where coaches can send texts, emails, and push notifications from their phone or from the web. MaxOne also allows color-coded calendars making organization as easy as possible, eliminating any confusion on schedules or events. Teams and coaches across the country love how affordable the MaxOne platform is when considering the versatility and variety of the services it provides. MaxOne certainly gives coaches a great bang for their buck in relation to other AMS software.

FYTT: Emerging from the fast-growing tech sector in Utah, FYTT provides strength & conditioning software for high-performance sports and tactical organizations. Developed within the University of Utah Athletics ecosystem, the product is designed and battle-tested every day by active practitioners. This has resulted in a superbly useful and intuitive application. The software’s key benefits include: Extremely fast program design using spreadsheet-like functionality, collaboration among coaches, scientists, and sports medicine staff to create a cohesive, holistic plan, long-term planning with the ability to quickly adapt for injuries and changing schedules, and seamless execution of both in-person and remote training using the tablet and mobile interfaces. Altogether, FYTT helps you provide more individualization and produce better outcomes. Coaches spend less time monkeying around in spreadsheets and more time practicing the art and science of high-performance training.

The list above will surely grow even if companies go out of business, which is a notable fear of teams worried about committing to a product that orphans them later. Smaller products are being launched, meaning much of the growth is in specialty solutions, but even those companies feel compelled to widen their services to accommodate fickle clients. There are other products on the market being used as replacement AMS products, such as business management solutions and developer tools for collaboration.

Not included in this list is the new system from Microsoft that recently launched. The reason we didn’t include it was because any platform must have two years under its belt for us to evaluate. Also not listed is Mladen Jovanovic’s software, Athlete SR, a specialized program that includes a rapid and effective way to capture both session RPE and wellness questionnaires. While Athlete SR is not a full AMS product, its value is more effective data collection and having the right tools to maximize the subjective monitoring process.

What You Need to Know Before You Trial or Buy

Overall, the entire market is the Wild West, and many teams and colleges are simply unsure about what they want, tending to buy only because other competitors use an AMS product. Several teams have built their own system or collaborate with different platforms that are not listed, such as Kitman Labs. The key is to decide what your needs are and how much time users have or want to invest.

The worst thing a team can do is having meetings with companies without having the actual users give their feedback. A vital reminder is that the goal of an AMS product is to save time and clarify roles for who should be doing what. It is not about the number of features the product has or who is using it when making a purchasing decision.

Before buying or even trialing, create your own list of expectations, send them to the company, and ask if they can fulfill those needs or provide additional ideas if a gap can be filled with a complementary smaller product bundled in. Commit to using it for a year before thinking about other products. Then, after using it, decide if it satisfies your needs and performs what you need it to do. Talent, not software, is usually the winning reason why a team succeeds or fails, so don’t stress too much about picking the perfect product.

Foot Pressure Mapping

An In-Depth Buyer’s Guide to Pressure Mapping in Sport

Buyer's Guide / ByChristopher Glaeser

Foot Pressure Mapping

In the last two years, there has been a growing shift in sports technology from measuring general body motion to measuring foot action. With a quarter of the bones located below the ankle, the foot complex is a very difficult joint system to evaluate and an even harder system to manage. In the next five years, pressure mapping is going to explode, with several companies all fighting over the data to monetize the capture and analysis of athlete gait. Of all the buyer’s guides from SimpliFaster, this is the most demanding subject area yet, and perhaps the most important part of helping athletic performance.

What Is Pressure Mapping in Sport?

Pressure mapping sometimes gets confused with force analysis, as the data is similar and the charting of a jump may look nearly identical. The main difference between force plates and pressure is that the former is direct objective kinetic measurement and the latter is more descriptive of the application of ground reaction forces. If you want to know how much force is interacting through the ground in jumping or other sport action, plates are appropriate; if you want to know how the foot applies forces for anatomical reasons, pressure mats and in-shoe systems are appropriate. The most-common reason pressure mapping isn’t a well-known area in sports is because the technology is extremely difficult to consumerize, as both the sports and medicine industries are extremely demanding and companies tend to allocate resources to research and industrial markets instead of coaches and sports medicine professionals.

Plantar Pressure Map
Image 1: Most of the data coaches want is simply on how the foot is functioning during walking, running, sprinting, and jumping. Other sport-specific actions can also be evaluated, liking kicking and lateral agility movements.

Two primary options exist for pressure mapping equipment: a mat for barefoot analysis and insole technology designed to measure inside a shoe. One system alone doesn’t tell the full story of what is going on, as both barefoot and in-shoe analysis are needed to see how footwear interacts with the foot strike of the athlete. The understanding of pathomechanics and clinical examination of the lower extremity are far more important than the brand of technology selected.

Mat Analysis Benefits and Limitations

Mats are still relevant today, as wearable devices are only appropriate in-shoe and barefoot evaluation needs a mat. Barefoot is a pure evaluation and, due to the fact it’s “naked,” it’s nearly impossible to apply systems that can capture detailed motions of the foot. It’s not easy to measure plantar pressures of the sole of the foot without a pad or mat. Mats—specifically walkway products—give orientation information on the foot strike, such as how the foot lands in time and space. Most in-shoe products just capture the data in a vacuum, but newer products are adding sensors to help assist with orientation perspective.

Foot Pressure Mat
Image 2: Mats are fine options and essential for barefoot conditions, in order to see how the natural foot structure is functioning. Many programs use mats for simple evaluation but should also consider in-shoe evaluations.

Professionals can use mats for unshod foot strike, but you miss a lot of valuable data when footwear is added to the mix. Unfortunately, it’s not a complete solution if you don’t evaluate the addition of cleats or athletic footwear because some mechanical changes occur when the foot is shod. In order to improve shoe design, the interaction of the foot, shoe, and ground must be combined.

In-Shoe Benefits and Limitations

It is very difficult to use an insole sensor system because most of the technology requires a compromise somewhere in the system, usually with the sensor density, sampling speed, or size of the hardware. As of July 2017, no company has an in-shoe product with hardware that leads in all categories; the bulky products usually have superior sensor data but they also have cumbersome harnesses to relay data to a laptop or desktop. The more mobile the product, the more likely it captures less information, but the data is more natural. For example, some systems that have wired connections will create a gait disturbance, thus interfering with the quality of the data even if the sensors are more accurate and precise.

Moticon Ortho
Image 3. In-shoe systems have evolved to become ultra-thin and completely wireless, a milestone necessary to gather accurate and valid data. Moticon insoles are now available after years of development, and sample at a solid rate for more athletic tasks.

Overall, in-shoe systems compromise the data width and depth in order to provide mobility. Many of the products in the wireless pressure insole market fail to live up to the research-grade quality needed to actually do something productive with the data, but their smaller price points lure coaches and sports medicine professionals into buying them. This will change in the next few years as the market is large enough for innovation, but it will take another year after that to validate the claims of the new systems.

What Are the Key Measurements of Pressure Mapping?

Five metrics that are pragmatic and actionable exist with pressure mapping, as some measurements can’t be changed because they are anatomical and not responsive to interventions. The problem unique to pressure mapping analysis is that the data is multidisciplinary and requires a very collaborative and integrated staff to fully solve the problems encountered.

Without clinical evaluation, pressure mapping is just guesswork. Share on X

Here are the five primary and unique measurements of both in-shoe and mat-based systems. More metrics exist that are useful, but for the most part the five below are common and universal to all systems.

Gait Curves: The most common and familiar metric with step analysis is the force-time gait curve we see with force plates and pressure mapping. Walking and running have typical norms, and the staff’s responsibility is to identify negative changes and possible dysfunctions from asymmetry due to injury. Baseline testing is still uncommon, so most teams are still evaluating late in the injury process, usually after repeated problems or re-injury.

Gate Time Pressure Plot
Image 4: Pressure and time curves, similar to force plates, are great for identifying changes in foot function. Simple line plots are great ways to see how velocity and pressure change during stance, walking and even sprinting.

Center of Pressure: The center of pressure, or CoP, is a specific measurement in both in-shoe and mat systems. CoP measures the calculated trajectory of the entire foot strike based on the surface area and pressures of the step. Not only do systems look at the trajectory and path of the center of pressure, but they also look at the speed within the beginning and end of the foot strike. Interpreting CoP is difficult without a lot of expertise, because each foot must be evaluated structurally and functionally. A fast and uncontrolled CoP is just as dangerous as slow regions that have mobility impairments, such as turf toe and other joint restrictions.

Symmetry Profiles: The measurement of symmetry is common because a change in mirrored balance usually indicates a risk of injury from acute dysfunction. There is normal and sometimes necessary asymmetry in sport, but interpretation of the changes or current functional outcomes is up to trained professionals. Right and left symmetry serves as a baseline to situations when pre-injury values have not been obtained.

Topography Mapping: The simple animation of pressures, usually shown with either 3-D values or color schemes, is the raw presentation of each step. The visualization is like an MRI, as an expert must view the data to fully exploit the benefits, but the value of this data plot is that laypeople can identify obvious problems, thus connecting the process to all parties.

Regional Evaluation: A less-common mapping process that varies in both application and accuracy is the segmental analysis of pressure profiles. Segmental analysis is estimating the joint action or foot mechanics through calculations and time periods. Many of the companies in the market try to prescribe orthotics by using this process, and the outcomes have been, on average, very poor. Without clinical evaluation, pressure mapping is just guesswork, because some changes could exacerbate patterns, but sometimes the appliances may work. Advanced modeling is where things are going in sports podiatry, and we see some elite teams leveraging it, but some high-profile teams are missing the boat entirely.

System Software and Third-Party Integration

The market of pressure-mapping hardware usually has software that is functional, but nothing spectacular for the most part exists from companies. The strongest software option is from Tekscan, as they have a strong history of refining the product. Some programs are designed to skip analysis and go right into orthotic fabrication and, for the most part, they provide little value beyond small tweaks to plaster casting or laser molding.

Due to the need for multiple data types to synchronize capture events, many of the products have recording triggers and plug-ins to ensure video, EMG, force plates, 3-D motion, and other information sets. The only drawback to pressure mapping is the lack of format-agnostic analysis tools that can important any file type to do a deep review of the mat or in-shoe data. Currently, some products can merge raw data to run some analysis, but nothing on the market now impresses the international experts.

Many of the companies have partnered with manufacturers of over-the-counter orthotics or customized products, but as we mentioned earlier, without clinical evaluation the process is severely flawed and prone to error.

Education and Application Resources

Educational services, such as manuals and user groups, are the most limited area in pressure mapping. Some companies do webinars or provide a few white papers, but hardly any of them are known as thought leaders. A common approach is to have a noted authority conduct a one-day workshop for customers, but due to the travel demands, they are difficult to attend and are too general to appease the wide range of professionals in need of education.

Clinical Evaluation of Feet
Image 5: Technology without education is not ideal, and medical evaluation of the foot is essential or staff will be hampered by what to do with the data. If you don’t evaluate the foot properly, the connections to interventions are very limited.

Research with pressure mapping is also very limited for several reasons. First is the lack of foot evaluation for each subject, as foot type is not a static measure, but a comprehensive profiling of the structural anatomy, current joint mobility, and lower extremity function, as well as evaluation of the shoes. Analogous to blood transfusions, many interventions fail not because of intent, but because each foot is unique enough to require specific, rather than blanket, interventions.

It is very probable that as the adoption pattern increases, the market will increase the ecosystem of added-value consultants and educational partners. Regardless of the current drought of experts, before investing in the hardware, education should be the first priority.

Interventions and Staff Responsibilities

Typically, there are three common tiers of expertise: performance staff, sports medicine, and sports podiatry. Roles and responsibilities must be aligned for pressure mapping to succeed, otherwise success will be impossible. The unique challenge to pressure mapping is that the data is useful to many members of a sporting organization, but managing the information and what it can provide is difficult. For example, a specific cleat may have problems that require shoe modification by the equipment manager, but he or she may not know how to determine which athlete needs specialized changes. Orthotics is another example, and the NBA has many vendors providing appliances without a shred of evidence that the intervention does anything but add a modeled carbon fiber insole.

Image 6: Custom orthotics are the primary intervention now, but as 3-D printing increases, athletic footwear will become more customized. Performing analysis on the footwear, as well as pressure mapping the foot, is the future.

Shoe design is another area that is, shockingly, left without many checks and balances to claims or accountability. Like the common toothbrush, the marketing language is often infectious, vague, and built on pseudo-science. The shoe design industry is more art than biological function, and this is because most customer base their buying patterns on aesthetics and not individualized function and personalization. Buzzwords like “pronation control,” “stability,” “high-tech cushioning materials,” and now “barefoot simulation” are polluting the sports world. While this topic is beyond the scope of this review guide, the role of pressure mapping is to ensure what is applied to the athlete is indeed working.

The Top Systems on the Market

Based on market saturation and adoption rate, most of the products listed are used in research and clinical settings. Some companies provide both an in-shoe product and mat device, but others just specialize in one or the other. It is important to remember that, for a comprehensive evaluation of complex problems, it’s wise to use both in-shoe and mat systems to tease out more information. However, one measurement can provide a lot of insight. Here are the top products on the market.

Tekscan F-Scan and MatScan: This Boston-based company has an array of medical and dental products that use their film-based pressure system, and the F-Scan (in-shoe) is going through a redesign process. The MatScan provides two primary options, a single step solution and a walkway product. Tekscan is a leader in both the education side of the space and with their software, but they’re limited by hardware that is outdated and bulky.

Tekscan should be used for walking and some treadmill evaluation, and ESPN’s “Sport Science” featured it in the past. The sampling frequency and resolution is ideal for sports podiatry and is the most clinically powerful of all the systems. Walking analysis and linear locomotion is the backbone to clinical evaluation because injured athletes are unlikely to perform movements that are more sport-specific. A lot of information can be found with walking analysis and from slower velocity running that can be sufficient to making progress with return-to-play decision-making.

Moticon: Moticon is the Porsche of pressure mapping, as their insoles are completely wireless and don’t require any transmission equipment outside the shoe. With nothing but a pure insole, Moticon is the future. The limitations of the product are the sensor density and sampling frequency, as well as the software. What this means is that events inside the shoe are going to have low resolution but are still strong enough to get gait curves and athletic motions that you can never get with mats or the like.

The future will be flooded with products like Moticon because they are the only tool that can monitor training. While the Munich company only recently entered the market, they have been working in sport for nearly a decade and understand the demands coaches and sports medicine require. Moticon is a strong solution for those wanting solid data with an emphasis on simplicity and mobility.

RSscan: The Belgian company made a tremendous comeback with its new footscan product and partnership with Materialise, but they are entering risky waters with their orthotic fabrication algorithms. The hardware is a mat or multi-step walkway, and it includes software that is elegant but limited. Seven years ago, the website looked like the company was barely solvent, but now they are making a lot of strategic and logical business development moves.

The company is more known in Europe, but has made a few connections in the U.S. market and is working indirectly with an NFL team in the Northeast without much fanfare. The company has a foot scanning device called the Tiger 3D scanner, and it’s a brilliant option to model the structural shape of the foot. However, it doesn’t have medical imaging, so it’s more for comfort and fit than for function. Using the 3-D scanner with pressure mapping is the future of performance and rehabilitation.

Medicapteurs: This French company has a small niche with its two products, the WIN-TRACK and WIN-POD systems. WIN-TRACK is appropriate for comparison because it uses dynamic pressure mapping versus a more static evaluation like the WIN-POD option. Like the MatScan, the S-Plate is a single-step option and is promoted to help with diagnosis of the lower extremity. The company is more clinical and it’s international, with distributors worldwide. The software is current but is not notable compared to Tekscan. Perhaps the most noted element is that the design of the product is aesthetically pleasing and intelligently crafted, with each system functioning well and providing solid data.

Novel Pedar: This German company is well-known in the research world, and they provide a more permanent product than Tekscan. Instead of disposable films that last only for a handful of uses, the product is reusable. Studies for soccer widely use Novel’s pedar-xf product for obvious reasons, as they collaborate with leading cleat manufacturers for product development. Pedar, like Tekscan, uses a very dated but necessary transmission harness, as the data requires a lot of bandwidth. The excessive wires and cumbersome “data fanny pack” make it impossible for real-world monitoring. Pedar’s software is on par with most on the market, but is a clear step (no pun intended) behind Tekscan. The technology requires recalibration and maintenance, but due to the fact none of the sensors are disposable, many researchers like the system.

The Orthotic Group (TOG) GaitScan: The Orthotic Group’s system, called GaitScan, is a smaller player but still relevant. The Canadian company’s strength is understanding business models and reporting, along with the ability to monetize orthotic prescription. The product’s core weakness is that its automation removes a lot of clinical evaluation necessary to give athletes the best option, since a barefoot walking step is not enough to do much outside of very general orthotic prescription. Many orthotics are prescribed without enough thought and analysis, leading to a worsening of the condition or at least failing to do anything measureable. Some systems like the GaitScan can help many patients with shoe comfort, but for athletic needs, the system isn’t appropriate. Still, comfort is hard to measure as it’s very subjective.

Roughly a dozen more companies and products could be listed, but many of them are out of business, struggle to gain market traction, fail to provide accurate data, or are just concept projects looking for venture capital. Unless the products provide enough impact for research and professional use, including them on a longer list is not fair to the reader. Expect the list to grow dramatically in the next few years, however, with products like Moticon becoming available.

The Future of Pressure Mapping and Market Speculation

Pressure mapping technology is a revolution for the right professionals, but inappropriate for casual users and that does include most coaches who lack the clinical ability to evaluate foot function. Like any tool, the purpose of the insole measures or mat system is highly dependent on the skills of the user. Professionals should have a working idea of what they want to do with the data, and pressure mapping systems and analysis software isn’t for everyone. The investment in the technology requires time, expertise, and experience solving problems mentioned earlier. Pressure mapping removes much of the burden and time with the indirect forces it measures, and sport performance and sports medicine finally have the right information for better results.

We have seen roughly 20 systems firsthand in the last five years, and the evolution of this market is ironically moving at glacier speed, even though it’s a technology. The future will feature more insole type products and third-party analysis software to connect the data to 3-D printing tools. While the prices will likely be lower entry points, the overall cost of solving foot function areas will grow, due to the entire ecosystem expanding. Pressure mapping technology is ripe for Cambrian explosion in the sports world, so continue to look at the space over the next few years as it’s going to be a standardized part of sport performance and rehabilitation.

CoachMePlus: Athlete Management System for Decision Making

Blog| ByBrad Stenger

Basketball Players

Basketball Game

The era of sports science in the world of competitive team sports is just getting started, but the movement’s technological underpinnings are beginning to settle. Motion sensors and computer vision track athletes movement patterns and force production. New platforms for chemical sensors tell more and more about athletes’ physiological makeup. And the simple, everpresent questionnaires, anthropometric measures, weigh-ins and heart rate calculations have proven value. All of that data gets funneled into computer interfaces, and sports management moves irreversibly towards evidence- and analytics-based decision-making.

Teams will prioritize some data and ignore others. They will emphasize some results and downplay others. And they will be ready, or not, for the next-generation of sports science tech to come on-line. Those choices, for better or worse, are becoming a sports organization’s recipe for athlete performance, the secret sauce of their team’s won-lost record.

One core piece of emerging sports science technology is Athlete Management System (AMS) software (like CoachMePlus). Think of it as a scaffold for teams to build their sports science programs and their secret sauce. The increasing adoption of these software platforms speaks to the value they have for teams, but heads up, these are new products in a relatively new market.

The newness of AMS’ products has implications for customers, namely:

  • These products will change, evolve and improve.
  • A community of technically-minded AMS users will emerge, connect, and in time, grow to define itself.
  • AMS’ technical advances will lead to users’ (and teams’) innovations in workflow, analysis, and tactics as the product developers and the community make progress toward interface and usability standards.

Culture and community are forms of collaboration. (So are sales, software development, and transition defense.) Successful collaboration defines teams’ success. And collaboration will be critical to shape how teams take to an athlete management system and make it into something valuable, now and in the future.

Understanding the Athlete Management System

It’s best to know how to walk before you learn how to run. Progressions are essential for athletes’ development. And no surprise, there’s a progression for moving through the learning curve of sports science collaboration and AMS adoption.

Team sports at every level benefit from measuring athletes’ performance systematically. The decision to begin measuring starts an organization down the path of applied sports science. More sports science decisions follow, and a big one is whether to purchase and use an athlete management system or to stick with a custom solution, often assembled from Excel spreadsheets or custom databases. Either way, AMS or no AMS, the data collected and the interfaces for the athlete data are going to be as much a part of the makeup of that team as any staff member, any trainer, any player, any coach.

The athlete performance data and interfaces are an opportunity for competitive advantage; together they are the secret sauce teams use to assess talent, develop players and, ultimately, win games. The measurement technologies, in practice and from vendors, are often new and, in some cases, still emerging — biomarkers, sleep, FMS, player tracking, force plates, RPE, questionnaires, Catapult, and Omegawave.

CoachMePlus Partners
Figure 1. Vendor partners will get teams all kinds of data. Making it useful is ultimately up to the teams.

AMS software, like CoachMePlus, is, by necessity, opinionated software. It’s software with a vision and an approach for how best to get work done. CoachMePlus’ vision and approach come from the best practices of applied sports science. (Also, the opinionated-ness is not a lack of flexibility or control for users; users have both. Lots of both in fact.)

If you use Microsoft Excel or something else custom (and less opinionated) to manage athlete performance, you are in complete control of the data, it’s input, output, and management. You are the developer and the user, and out of necessity, you make lots of data management and presentation decisions. Excel is not opinionated software, and it creates more work.

Most times the decisions that get built into the user interface involve steering a user through the tasks that software has been built to help with. “Software requirements” are what software developers call these task definitions that, once built, are important elements of the software’s services. Tasks that are not defined well enough to be included in requirements documentation will not get designed into the user interface, and determining requirements is the crucial early step for building useful digital tools and services.

Having an already-built, commercial AMS helps a team to avoid starting its applied sports science program with a completely blank slate. Fill in the forms and click buttons on whatever starter template to get to a useful place with the technology. But work remains to go from starting out with the basics to making an AMS into something that reflects a team’s approach to sports science.

There can be significant advantages to going without an AMS though. The legwork in using Excel, or even paper, to manage athletes health and performance creates a useful, hands-on, personal relationship with athletes’ data. Manually entering data can be an effective, practical way to see athletes’ patterns. It is also time-consuming, sometimes to the point of being impractical for taking lots of measurements and for managing larger numbers of athletes.

CoachMePlus User Interface
Figure 2. Data entry can be onerous, but it can also be a way to gain insight for whoever plugs in the numbers — coaches, trainers or the athletes themselves.

An AMS might be necessary, but it’s important to understand what it means to surrender some degree of control to an opinionated technology. It’s also important to understand what you as a software customer can do to influence, evolve and improve opinionated technology.

A team can guarantee that its data systems evolve according to its needs by developing its own systems, but the team that goes with a commercial AMS needs to remain aware of how changes in data can lead to workflow changes that might call for changes in the user interface. The task definitions that are scoped out as requirements can be inaccurate, imprecise or fail to keep up with users’ needs. It helps to remember that sports science is a young discipline, and the technologies are new.

The inability to make sense of the data takes time away from coaching, training and otherwise helping athletes. The situation is a user interface failure. Like so many efforts that do not succeed it is also a learning opportunity, a chance to examine what’s happened, apply the lessons and make progress.

CoachMePlus Data Analysis
Figure 3. Four days of data collected by a 12-player professional-level basketball team occupies 87 spreadsheet columns. Context is lost. At-a-glance observations about the changes in the physical condition of the athletes are difficult. A more robust user interface would help.

Software tends to work better when the task and the analysis are well-defined. Technology gets better as developers, designers, and engineers improve their understanding of how it should be used. Requirements that start off murky eventually become clear.

“Design Patterns” are what often maps the requirements for a user task to its implementation in a software interface. Design patterns also provide a helpful way to understand how good software takes advantage of modular components that work together. One design pattern is a reusable solution to a specific problem, like the easy solution to gathering health data by assigning clickable zones to a simple representation of the body. Good software is built component by component, where each component does its job, much like what coaches ask for from players. Design patterns provide a common language and helpful shortcut to bridge what users need from software to the code that helps do those tasks.

Design Patterns
Figure 4. The data represented on a spreadsheet for a Functional Movement Screen. Or the same data rendered using a representative point-and-click interface, an example of an interface solution from a Design Pattern.

More than with any other task, an AMS shines when asked to provide an overview, helping busy users see the big picture on a dashboard: that athletes are thriving, who might be injured, what practice patterns seem to get the desired results.

Stephen Few, a noted information design consultant, has articulated what makes for good dashboard design, “Visual monitoring involves a series of sequential steps that the dashboard should be designed to support.”

  • The user should begin by getting an overview of what’s going on and quickly identifying what needs attention.
  • Next, the user should look more closely at each of those areas that need attention to be able to understand them well enough to determine if something should be done about them.
  • Lastly, if additional details are needed to complete the user’s understanding before deciding how to respond, the dashboard should serve as a seamless launch pad to that information.
CoachMePlus Athlete Performance Profile
Figure 5. CoachMePlus makes extensive use of data dashboards.

It’s here, at the dashboard, that the AMS and the team using it have to be in sync. Software for athlete performance is going to incorporate a wide range of data inputs: weight, body composition, hydration, questionnaires, velocity-based training, sleep, nutrition, blood markers, fitness tests, movement screens, heart rate, heart rate variability, athlete tracking, readiness monitoring, load, video analysis and game analytics. The dashboard needs to reflect the priorities of the team, or it isn’t putting users’ attention where it should go.

Applied sports science depends on an effective athlete management system that has to do two very different things at the same time. It has to value the simple presentation of good dashboard design. And it has to capture the complexity of all the different facets of athlete performance. The tension to maintain simplicity while also adding new complex features is another fundamental consideration of user-center design.

The tension between design simplicity and feature complexity is likely always to be an issue for athlete management systems. New sensors and data sources continue to be invented. Teams are adding sports science personnel who bring a range of backgrounds and place new demands on the software. If you agree that AMS is opinionated software, you will want to pay attention to how an AMS is set to evolve on these fronts in the future.

Athlete Management System
Figure 6. The complexity involved with measuring athlete performance can be staggering, and it is increasing.

In addition to the tension between simplicity and new features, supporting collaboration among users is another design dimension that will shape the future of the AMS. Collaboration plays a role in turning information into actionable insights that will improve athletes and teams, and in using the evidence at hand for organization decision-making about players.

Authorities on effective collaboration point to the “shared artifact” as the thing that everyone has in common and which provides a single frame of reference for the group discussion. An AMS can be the shared artifact for all of the different stakeholders in a sports organization that helps them work together.

AMS Group Reporting
Figure 7. The AMS interface needs to transition effectively from views that serve individual users to group views that enable collaborative insight and decision making.

This is the AMS progression for doing sports science:

  • Start by simply entering data.
  • Do basic analysis.
  • Develop a unified dashboard.
  • Incorporate a wider range of sports science data inputs.
  • Increase the complexity of the data interface.
  • Ultimately make the AMS a tool for collaboration.
  • A progression, yes. An easy progression, no.

Advocacy, Customers and the Future of Athlete Management Systems

The goal for CoachMePlus (and our product development roadmap) has us getting more flexible and more collaborative as the product evolves. Inside our organization we are building out the APIs, data modeling tools and dashboard functionality for our internal product teams, These are the technical tools that will improve our internal collaboration, setting us up to work better with our customers and partners.

Already, customers can call with an idea they want to try and our tools enable less than a 24-hour turnaround. Eventually, the APIs, modeling tools, and dashboards should become self-service interfaces for teams to take greater ownership of how they use their data and which will help teams to extract maximum value of athletes’ data.

There are many pathways to realizing potential; it’s true for athletes, and it’s true for technology. Each athlete management system is going to have unique elements for the team operating it. If the team has someone whose job is to administer the AMS, all of the ongoing change in sports science is going to make for challenges.

High up on the list of challenges is the way an AMS administrator has to represent all of the different stakeholders and be an advocate for athletes, coaches, clinicians, trainers and team management as he or she guides the evolution of the AMS and the workflows a team uses with the AMS. The point: It’s not enough to simply passively administer the team AMS, not when these products are set to evolve rapidly, even within the timeframe of a team’s season.

AMS administrators are advocates when it comes to working with CoachMePlus or any of the developers of the technology. Administrators are the voice of their team’s otherwise voiceless stakeholders who benefit from the technology. The better those team-side communication channels are working, the more aware AMS administrators are of their needs when they have their conversations with their technology partners.

Teams that make the most out of sports science will need to make the most of their athlete management system, and that will be difficult for teams that choose to be passive participants in AMS evolution.

Ultimately teams will get the AMS they deserve, based on how much they participate in moving the technology forward. In time, there will be communities of practice for applied sports science technology, but until that day arrives, the quality of the tools depends on the quality of the collaboration on teams, between teams and technology providers, and among everyone who comes together in the nascent community of sports science technology developers.

Participation is not mandatory and karma is not guaranteed. But please share so that you and your peers in the present and the future may benefit.

A Buyer’s Guide to Flywheel Training Equipment

Buyer's Guide / ByChristopher Glaeser

 

Proinertial

Ever since the invention of the wheel, technology has evolved to enhance the training of modern human beings. While much of the current interest in flywheels is the result of the resurgence of eccentric training, the reality is that flywheels are about redirecting momentum, not providing a true eccentric overload. Isoinertial training is old news, but the new companies providing equipment are also providing fresh ideas that dramatically improve the outcomes of training. The promise of this article is simple: We outline the necessary components of a great flywheel product and list the companies in the industry who are leading the way.

Before the Space Race: A Very Brief History of Flywheels

Usually the story of flywheel training starts with Per Tesch and NASA, but the truth is it’s likely somewhere between the first potter’s wheel and the 1970s when isoinertial exercise machines were invented. Flywheels are used today in other industries outside of sports equipment, so they are not unique to exercise. Sports training flywheels are simply disc-based machines that spin and provide an efficient way of conserving energy, usually through squatting or pulling motions.

Flywheels are not eccentric overload machines that increase the force beyond the concentric contribution from the athlete. The machine does not create eccentric overload; it’s the exercise technique in receiving the load that is truly an increased eccentric muscle action.

Several companies provide flywheel training devices, and some have taken the equipment to new levels with their designs, but the evolution is only a refinement, not a quantum leap. The reason is obvious: Flywheel technology is primitive and exercises are, for the most part, ancient. So why the increased popularity of flywheel systems? The answer is simple: The science is gaining (pardon the pun) momentum. The proponents of loading the body to assist in rehabilitation—usually with more aggressive approaches than in the past—are driving interest in flywheel training. Today, we see about a half-dozen international providers with flywheel equipment, and this is likely to grow with the American companies starting to spring up now.

The Biology Behind Flywheel Muscle Contractions

What do flywheels do uniquely to muscles and the nervous system as compared to conventional gravity-based options like barbells and bodyweight exercises? Recent investigations using tensiomyography indicate that flywheels provide a specific stimulus that challenges the neuromuscular system differently, and those differences have shown up in other research studies that include performance testing.

Flywheels challenge the neuromuscular system differently than barbells or bodyweight exercises do. Share on X

Flywheels resemble an old lawnmower start, and finish with a rapid eccentric rebound. A barbell squat begins with the bar lowering until the athlete redirects the load up concentrically. Each rep usually includes a rest period of a second or more, then the work continues again with another eccentric to concentric pattern. Flywheels have no break in the work being done, as the repetition constantly cycles from concentric to eccentric activity. Additionally, the work being done on the eccentric portion experiences a redirect of velocity from the peak velocity of the concentric side. Thus, the rate of the early eccentric work is dramatically different because free weights respond to muscle tension and gravity.


Video 1: Split squats and lunge exercises need a base of support that enables a free movement pattern, so some platform models that are oversized really help coaches get more out of their investment.

Peak eccentric forces are about how the body receives the redirected energy from the flywheel, not about the machine in any way boosting the force. True eccentric overload occurs when the total work done is greater than what was either volitionally provided by the preceding concentric action or what could be done if the athlete was to evoke a maximal concentric action. Researchers are exploring muscle architectural changes or morphological adaptations to muscles that favor performance and injury resilience benefits.

So far, we do know that any eccentric overload that creates a lengthening of the muscle is more resilient to injury, especially in the hamstring group. Hamstring curls using flywheel training do provide a lot of torque, but only when a partner assists the concentric portion does the eccentric work become very interesting to coaches and researchers. Classic approaches like two legs up and one leg down are examples of eccentric overload without the need for a flywheel, and are back in use due to the Nordic hamstring exercise becoming popular in sport again.

Generally speaking, most of the techniques using flywheels are about generating a larger-than-possible force into the machine, such as a partner-assisted motion or bilateral concentric to unilateral receiving exercise. What coaches are trying to do is train the body differently eccentrically or overload it more by using an exercise pattern that exploits the ability to transition to a different motion after the flywheel redirects the forces. An example of this is a squat to Romanian deadlift, where the athlete is squatting concentrically and fighting the eccentric action early with the Romanian deadlift action.

Common Design Choices of Flywheel Training

Flywheels usually come in two options: a platform with a disc wheel or a cube with a cone-shaped mechanism. Most flywheel training platforms are for squatting movements, while the cube options are for total body movements and rotational patterns. Both options can be used for leg training, but the squatting platforms are popular because they are a portable lower body option for soccer teams. Due to the culture of the sport, getting athletes to train before they leave the pitch is a needed benefit for teams.


Video 2: In this video, Mark Verstegen demonstrates various exercises using the VersaPulley system. The VersaPulley flywheel is a conic option that uses a baseboard for lower body motions.

Platform systems are the most popular in the industry, and nearly every company has a “squat” device of some sort. Most systems are about 1 meter long and half a meter wide, and resemble a table saw. Most of the systems have the flywheel outside and on the top of the platform, but the kBox has the system on the bottom of the platform and uses small legs to keep the flywheel free. The cables are mainly either straps or rope-like materials, and the discs are alloy metals with a hexagonal hole in the middle. Companies usually provide harnesses for squatting, similar to a vest or backpack.

Cube systems are mainly conic-shaped flywheels, so the cables can wind and unwind smoothly. Cube or box systems provide opportunities for exercises that require more movement, like upper body exercises that use rowing motions. Cube systems are also solid solutions for squatting and lunging motions, and many American coaches are familiar with the VersaPulley popularity of the early 2000s.

Due to the portability of the machines, coaches tend to use them outdoors or bring them out in the weight room. Some of the companies allow for mounting for clinics and therapy rooms, but for the most part these systems are more mobile in design.

Quantifying the Loading of Flywheel Training

A lot of high-level math is needed to get precise work transferring through a flywheel, as countless variables can interact with energy creation, storage, and redirection. Due to safety considerations, training flywheels collect energy, but don’t enhance the energy or speed they receive. So, treat flywheels like a rubber ball rebounding off a surface, not an underhand softball throw to a home run monster, creating more energy than it receives. Coaches have to trust the companies that build the machines to have valid measurements, since small details like weight and radius must be very precise or the estimations will be inaccurate. Additionally, other details, like the materials used, angular velocity, and additional weights near the edge, require a lot of development time and effort to ensure the calculations are accurate.


Video 3: The video above shows the instant feedback using the Desmotec system. If you are serious about flywheel training, you’ll want and need the quantification of peak forces throughout the workout.

The estimation of work done with flywheels can be made with different instruments, but for the most part the calculations are done from RPMs of the crankshaft or the use of a positional transducer. The kMeter was already reviewed, and systems like GymAware have been used to help display and record flywheel training work in the past.

Rotational energy is the consolidated work calculated from all of the sensors and instruments available and, while that is a fair summary, it doesn’t tell much beyond the work performed. Coaches and therapists at first want to know how much work is done per repetition of an exercise, but as they become more experienced, they are likely to want more specific context such as the time frames involved and the distance of motion of each repetition. Unfortunately, most of the problem with flywheel equipment is that the sensors are on the machine instead of the body. While it’s fine to see how a human interacts with a machine for the purpose of quantify output, we also need to know how athletes create the forces to understand how training is trending up or down. Coaches and therapists must be careful to not rely on one metric or score, as a number in isolation usually doesn’t tell much beyond the result of an action.

While slightly oversimplified, the sports training flywheel is a cable-driven machine that can quantify the work from the pulling action and the work receiving the redirected energy. The challenge is that, in general, stroke distance provides a better way to create force. However, receiving the load quickly usually decreases the distance of work and makes it difficult for the next rep to have the same concentric output. Also, if the athlete can lower their body to a deep receiving position, they may not be strong enough to handle the abrupt forces on their joints. The unique back-and-forth motion of the flywheel systems are a challenge to perform and quantify, as the need to see specific work done on parts of the body is far different than on the body as a whole.

Top Systems in the Flywheel Market

The top seven systems providers are all selling equipment to coaches and physical therapists for performance and rehabilitation. More companies exist in Spain than are listed now, as the market is extremely saturated in that country for some reason, but those companies are not selling enough and have not been around long enough to be considered. Expect a very dramatic change in the U.S. market at the end of 2017, as some creative coaches are likely to get involved in the flywheel space.

Exxentric kBox 4 Pro Platform
Image 1: The Exxentric Company just released the fourth version of their kBox, in both a professional size (larger) and a lite version (simpler and smaller). Small nuances are important to know, such as the retraction mechanism and the quality of accessories.

 

A good test to see the quality of a machine is spinning the flywheel with the disc and timing the duration of the rotation period. The longer the spin, the better the flywheel machine. Also, welding is more durable than using brackets, but most systems will last for nearly a decade, save the rope or strap system. Each system must be maintained though, so like cable or selectorized machines, physical maintenance is required. All of the companies offer accessories, but third-party vendors are important to consider, as they can provide very specialized harnesses, bars, and handles.

VersaPulley – Heart Rate Inc., the American company that makes the VersaClimber and other products, was founded in 1978. Known for their VersaPulley product line, the company has three models of conic isoinertial products, and they range from a portable to a platform to a cube hybrid system for more specific leg exercises. The mid-range product is a wall-mount system, and the company offers a rep counter and a display, but it’s not a tool that indicates actual force or power. Many strength coaches in the U.S. will remember VersaPulley was endorsed by Mark Verstegen before he transitioned to Keiser. Phil Wagner, the founder of Sparta Science, endorsed the product more recently.

Exxentric – Founder of the kBox, this Swedish company provides a series of platform options that use a band- or strap-based flywheel. The cardinal difference with the kBox is that it has a flat top; the flywheel crankshaft is under the platform, but it requires legs to keep the flywheel disc from hitting the ground. The product provides an excellent opportunity for those wanting to do deadlift movements and deep squatting, as no machinery is near the foot area. The kBox series has an oversized pro option, as well as a lite option for maximum portability. The strongest feature of the product, besides the flat foot area, is the kMeter, the sensor that transfers the RPMs of the crankshaft to useable data on iPads and iPhones.

Proinertial – This Spanish company has been in business for 10 years and is growing internationally. They provide multiple machines besides platforms, and can also customize for a very small fee. Their systems use Chronojump technology to calculate work performed by the user in training, and feature a rope-driven flywheel. Their products are very popular in soccer clubs and training facilities, and just entered the U.S. market this year. Proinertial’s product line includes a platform option with oversized boards for tall athletes, and their slant boxes are permanently fixed for lateral lunges and squats. The cube products are portable and can be mounted to walls, and they even have a leg press.

Desmotec – Similar to Proinertial, this Italian company has two primary models. Each model has customized features that are optional, like sliding mounts and a specialized platform option for therapists. The system is popular in soccer, and it has been on the professional market in the U.S. for years. The products are well-crafted, and their attention to detail makes them the sports car versions of flywheels. Several professional athletes have their own home systems and, like the previously mentioned companies, Desmotec offers a complete line of accessories. They also offer perhaps the most developed software, and data is captured via a linear positional transducer.

Space Wheel – The Space Wheel system is a combination product that is one part platform and another part pulley option. The Space Wheel doesn’t currently offer any sensor to calculate output, and the system is very barebones. The one strong area of note is that the product is arguably the most portable of all of the platforms, after the kBox lite. The Space Wheel is known for its spiral decorated disc that nearly hypnotizes the viewer due to the design. Space Wheel is a very small Italian company and has some traction in the market, but they’re not as visible as Desmotec.

nHANCE – nHANCE is known for their collaboration with Dr. Per Tesch, and their product line includes other options, like a leg press and hamstring machine. The squat platform system offers a connection to a third-party sensor for output measures, and has a long history with teams. One of their most popular products is the YoYo Leg Curl machine, which elicits a high amount of EMG activity. It is known to place a lot of strain on hamstrings—enough to create adaptations beyond typical curls. The company has not innovated in years, and is likely feeling the impact of competition.

RSP – The final company is from Vigo, Spain. The company has three systems: a pure conic option, a wall system, and squat system. Its products are very contemporary and they don’t have any sensors: all are conic-shaped flywheel systems except for the platform. Because they provide a smooth experience, the products are known for their rehabilitation benefits, likely for early shoulder strengthening post-operation.

These flywheel systems range from about $2,000-$5,000 USD, and accessories are all priced differently. Most of the time coaches want the waist belts, as the torso harnesses are more expensive. The sensors for quantifying work range from $500-$1000 USD, and connect to either a laptop or tablet. One major factor in the purchasing decision is the shipping cost, which adds at least $200 to the equation.

Educational videos and articles are the lifeblood for the products, since most sports training courses and textbooks don’t mention flywheels, except in passing. Some courses and conference exist, but they are usually extended infomercials and focus on the benefits of the product instead of deeper science. So far, the Exxentric company is the leader here, with other companies soon to be following suit.

What to Expect in the Future With Flywheel Training

Don’t hold your breath for a radical change in the market. Most of the cost of flywheels is the cost of materials, not the development needs. The real innovation is on quantification of the energy created and received, as well as nuances such as accessories and refinement to the construction.

It’s safe to say that flywheels are not going away soon. Several other technologies can provide isoinertial experiences, but they are more expensive. Although the price of motorized resistance is currently very high, they do provide true eccentric overload and the user experience and exercise options are better. Flywheels are going to be around for a while, due to the fact they don’t require much to work, and are a staple in many training programs.

The Warm-Up Smorgasbord: What and How Much to Choose

Blog| ByKen Jakalski

Athlete in the Buffet Line

One of the summer activities I have my cross-country runners do is throw a turbo-jav into a trash can. Since I give prizes for the winning toss, every time I do this my runners always want to take some warm-up tosses prior to competition. But are these warm-up tosses improving either their distance or their precision once competition begins?

Runners Throwing the Turbo Javelin
Figure 1: In the summer, I have my cross-country runners throw a turbo-jav into a trash can as one of their activities. I give prizes for the winning toss, so they always want to take some warm-up tosses first. But do warm-up tosses actually improve their distance or precision?

A classic study from 1957 provides us with an insight on warming up for an activity similar to my “javelin in a can.” Forty-six male students were given a five-minute warmup and then instructed to throw a softball as far as they could. The participants came back a little more than a week later and, like my javelin toss, they would win prizes (in this case, money) if they could throw the softball farther than they did previously, but this time without benefit of a warmup. So, what happened? None of the participants threw farther than they had before.

Does this 60-year-old study suggest the inherent value of a warmup for any movement activity, or am I simply “lobbing a softball” to those who want to use this as evidence to corroborate why it makes sense to do some kind of warmup activity prior to competition?

What Is the Goal of Warmups?

It is a complicated answer because the concept of “warming up” means different things to different coaches. Is warming up stretching? Is it a combination of stretching with various movements? Is it mental rehearsal? Lighting up the central nervous system?

The concept of ‘warming up’ means different things to different coaches. Share on X

Maybe it is all of these and more. But, if warmups are a smorgasbord of various activities with different purposes, do we need to fulfill all of these purposes in order for the warmup to be truly effective? The current debate on the value of static stretching is just one example of the confusion over which items from the warmup smorgasbord coaches and athletes need to put on their plates. That may depend on what specific physiological effect—as well as psychological effect—of warming up coaches most value, and there are many to choose from.

Is it muscle temperature? This makes sense since a temperature increase allows muscles to contract faster and with more fiber recruitment. For example, nerve impulses in people travel eight times more slowly than they do in frogs, which have much lower body temperatures. We know that a warmer muscle is likely to experience less damage, especially during eccentric contraction. Is it increased blood flow to the heart and muscles by way of movement that needs to be addressed? Might it be muscle plasticity?

Distance coaches will point out that a warmup results in increased oxygen and carbon dioxide exchange, and that a more-efficient oxygen transport means more available ATP. Others will contend that a warmup can reinforce important motor skills. I have always considered the warmup a valuable means to achieving competitive arousal. For example, Frank Shellock pointed out that a warmup leads to psychological increases in focus and attention, and that a warmup decreases the fear of injury.

We see examples of unique kinds of arousal techniques used in various sports. Football players will tap helmets together and punch down on shoulder pads, and boxers will glove their faces before the opening bell. Long jumper Mike Powell often slapped his face before taking off down the runway, and many sprinters still jump up and down a few times before backing into their blocks.

Others see the value of the warmup as a form of visualization—what Mel Siff used to describe as “imagineering.” You see this with wrestlers who jog around the mat as they mentally rehearse shooting for a takedown. Some athletes perform specific kinds of rehearsals right before a trial. Dwight Stones, for example, bobbed his head as he visualized his approach steps in the high jump. And there is some performance justification for suggesting that these activities are more than just ritual. Charles Duhigg described how, every night, Michael Phelps would play a mental recording of himself setting world records. Maxwell Maltz introduced this concept back in the early ’60s, and referred to it as “psycho-cybernetics,” the process of enhancing self-image through visualization and mental rehearsal.

Many elite coaches might also choose specific activities in a warmup because they intend to use them to spot any imbalances. In this case, the warmup might be considered a kind of movement screening. This makes sense, since most coaches and trainers say that the key goal of the warmup is to ward against potential injury, while at the same time getting athletes ready to compete.

But some warmup activities make more sense than others. I know cross-country and track coaches who have their runners jog a couple of laps or even a mile, then have them plop down on the turf or track to do 20 minutes of old-school static stretches, with each of those stretches held to a 10-count by the group leader. They then have those runners get back up and run another lap or two because they don’t quite trust that they are ready to race, or because they want to re-elevate things like core muscle temperature and blood pressure, both of which dropped back down during the static stretching. Some say they do this because they want their runners to “re-break a sweat.” Is the value of this approach more about its team bonding and ritual aspect?

I have always liked what Loren Seagrave and Kevin O’Donnell referred to as the “big warmup,” and many coaches include those activities in their pre-competition protocol. I like incorporating various kinds of skipping, hopping, or galloping done forward, backward, and laterally, and it’s extensive enough be its own workout. These kinds of activities seem to accomplish many different things, including elevating the temperature and blood pressure, and challenging runners neurologically. Additionally, since the group must duplicate the speed and amplitude of the group leader’s movements, athletes need to concentrate and stay focused. The activities I select are what I call “gravity constant,” emphasizing such things as timing, core stiffness, coordination, and reactivity.


Video 1: I like incorporating various kinds of skipping, hopping, or galloping done in all directions—forward, backward, and laterally—into warmups, and it’s extensive enough to be its own workout. Here, an athlete engages in complex rope skipping in all directions.


Video 2: In group warmups, the groups must duplicate the speed and amplitude of the group leader’s movements, forcing each athlete to concentrate and stay focused. I select what I call “gravity constant” activities, which emphasize such things as timing, core stiffness, coordination, and reactivity.

The Inclusion of Self-Massage Activities

In recent years, the warmup has involved activities for removing tissue micro-trauma from previous training sessions. Trainers often describe small “hot spots” or knots in muscles as trigger points. They no longer try to remove these knots by way of conventional stretching, believing that if these trigger points are indeed like knots, pulling on the ends of the knot via conventional stretching only further tightens them—kind of like the old Chinese finger trap.

Chinese Finger Trap
Figure 2: Warmups have evolved to include activities that remove “hot spots” or knots in muscles that are trigger points. However, trainers no longer removed these knots using stretches, as they now believe pulling on the ends of a knot only tightens them further, like a Chinese finger trap.

So, a form of self-massage has evolved. Again, at first this seems like nothing new, since the massage stick—which I used to describe as a rolling pin with bicycle handles on the ends—goes back more than 30 years.

Girl with Massage Stick
Figure 3: Instead of conventional stretching, athletes now remove muscle knots by using a form of self-massage. Here, an athlete uses a massage stick as part of her warmup.

Perhaps that stick, refined over the years by way of soft rubber knobs and waffles replacing the original hard plastic rings, will be viewed in a whole new way, thanks to Ben Affleck’s self-massage technique in the film, “The Accountant.”

Ben Affleck Self-Massage
Figure 4: Ben Affleck’s character in “The Accountant” uses a stick as a self-massage tool, potentially to help self-soothe after too much sensory stimulation.

The theory is that rolling applies pressure to tissue sore spots in the muscle, thereby breaking up scar tissue and adhesions, and thus releasing the trigger points. In this regard, the stick has now evolved to tubes—the original being just sections of PVC soil pipe—but now these tubes consist of various configurations of denser foam. These new massage tubes are now very popular.

Trigger-Point Therapy Using PVC Pipe
Figure 5: An athlete uses a regular length of PVC soil pipe to engage in trigger-point therapy. The theory is that rolling applies pressure to tissue sore spots in the muscle, breaking up scar tissue and adhesions, and releasing the trigger points.

Foam Roller
Figure 6: The massage stick has evolved from PVC soil pipe to popular massage tubes featuring various configurations of dense foam.

The technique used with these foam tubes has a technical name—SMR or Self-Myofascial Release. These rolling techniques increase both flexibility and range of motion through “autogenic inhibition.” And what does that mean? The tension the roller puts on the muscle causes the brain to relax that muscle to prevent it from tearing.

Trainers and therapists often progress to using tennis balls or lacrosse balls to target deeper trigger points, especially those in the back. There is no end to the therapist’s creativity here. Some tape these balls together to form what they call “massage peanuts.”

It Comes Down to a Matter of Taste

So, not only is the warmup a smorgasbord of choices, it also appears that even choices we make continue to undergo changes. I very much agree with Rett Larson, project manager for EXOS- China, who said that the “concept of the warmup needs to shift from simply focusing on the muscles of the body to embracing the multi-factorial nature of pre-training or competition preparation.”

The takeaway from all of this is that many techniques can activate muscles before training. Whatever coaches choose to implement in their warmup, what they are actually accomplishing may be the kind of neurological arousal that they believe best prepares their athletes for the demands of the sport or event they are competing in.

Coaches choose warmups they like through experience, but not everyone has the same experience. Share on X

Like a smorgasbord, we can sample a variety of warmup routines, but whatever we choose to maintain is really the result of an “acquired taste” for what we think works best. These are activities we come to like through experience, but keep in mind that they reflect an appreciation that others might not share if they have not had similar experiences with the athletes they train.

Cheetah Running Fast

5 Drills to Improve Vertical Force and Run Really Fast

Blog| ByChris Korfist

 

Cheetah Running Fast

My introduction to Dr. Peter Weyand came late last century on a snowy day at Benedictine University in Lisle, Illinois. Respected Illinois high school coach Ken Jakalski led a seminar featuring Weyand and his new research on sprinting speeds.

At the time, Kevin O’Donnell and Loren Seagraves were the rage with their Speed Dynamics VHS tapes. Every coach had their own copy. They could recite all of the drills from “A” skips to whatever the last alphabet letter they used. You weren’t a good sprint coach unless you had all of your athletes lined up doing the drills in unison.

I can still hear the sound of a good practice because everyone’s feet were hitting in unison. And in the back of all the coaches’ minds was the stride rate vs. stride length controversy. This was such a powerful, overriding factor that we even had sticks set out to work length or shorten the distance-to-do rate. And on acceleration days, we threw out the slats with rope to measure the lengths of acceleration. Those were the days.

Jakalski’s entertaining introduction reminded us of our journey with speed development, touching on such cool toys as the Kolka Thigh Trainer, Russian parachutes, and other well-marketed devices that caught the attention of desperate sprint coaches who had a spare Benjamin or two in their budgets. He ended with the statement that Dr. Weyand was going to change all of that. And he did.

Dr. Weyand is not a sprint coach. At that time, he was a Harvard University researcher, working at a nearby one-time Nike anti-aircraft missile control center. He had a force plate and high-speed cameras that recorded animals and people running. If my memory serves, he started working for the US Army to look into calorie expenditure and running. From there, he looked into birds running, like ostriches. That led him to limb repositioning.

In his paper “Faster top running speeds are achieved with greater ground forces not more rapid leg movements” (Journal of Applied Physiology, 89: 1991-2000, 2000), he determined that repositioning of legs was just about the same in everything he tested. (Everything except the common house cat. He had every kind of animal and human run on the plate but couldn’t get a cat to do it). He even inherited a lion that had started living at the facility.

What was cooler than the roaming lion was Weyand’s conclusion that what determines speed is the amount of force an athlete applies to the ground. This not only applies to humans but also to animals as well. The really fast ones—cheetahs, ostriches, greyhounds—hit the ground much harder than sheep, lions, and other slower animals. I have Boerboels. They are very fast for big dogs, just for about 50 yards. When they go by, you can hear the thud of their feet on the ground. When my really fast sprinters go by, it is like a drum. Weyand concluded that the harder you hit the ground, the faster you are. He compared the world’s top sprinters to other runners and found the same thing.

MBumba the Dog
That is my dog MBumba. He wins all short races. He can generate some force.

The seminar was a game changer. But, it was only a game changer in theory because no one gave any tips on how to develop the ability to put force to the ground. It was a brand-new game. Is it strength or stiffness that needs the work? Do we do a ton of plyometric work? Do we start lifting large amounts of weight?

Both create problems. Plyometrics are often supported by two legs and lack the challenge to the lateral chain that is so important for a stiff contact. The strength portion is too slow and sometimes not in the proper range of motion. I have seen many athletes who can lift the house but can’t run. Others can’t deadlift much but run like a deer. So where does that leave us?

Before I get to the weight room stuff that I found to be very effective, training the test is very effective. Sprinting itself can have a huge impact on vertical force. Like Tony Holler preaches, electronically timed short sprints are the best way to develop sprint speed. There is no way around it. Start with fly 10s and gradually spread out to 30s by the peak of the season. In The Rise of Superman, Steven Kotler writes about the importance of Flow. Flow is the neurological state necessary for optimal performance. Immediate feedback is one of the keys for Flow.

So at our practices, people scream out numbers so athletes immediately know exactly how they did. That creates a reaction in the brain to do better, or ride the wave and do even better yet. Every night after practice, I post times which show improvement (or lack thereof) from the previous workout. All this creates a positive environment. Most times, our practices become more competitive than our meets. So even if all you have is a short hallway, that’s enough for an effective workout. I have had the luxury of a 200m track for the last 9 years. All we need is a straight and that is enough for most of our workouts.

But, if you are short of space or want to change things up, you can try this workout I created several years ago. It has proven very effective for my athletes.

One

The first exercise is a psoas and glute exercise. If you read my previous post, “5 Effective Glute Exercises,” you know about the relationship between the glute and psoas. I want to establish this relationship in most of these exercises. I also want to establish the scissoring action of the knees.

In his book Strength Speed: Technology and Training for Sprinter Speed and Long Jump, Swedish coach Jan Melén shows the differences between athletes of varying levels and their knee lift. I think we all agree that faster sprinters get their knees high. Part of that knee height is a reaction to the drive onto the ground.

But there is also an element of psoas activity. If the psoas is not firing, the knee lift will come from the hip flexors in the thigh and will not have the power to lift the leg all of the way to a position with the torso past 90 degrees. This exercise drills the knee lift. The athlete has a strap around the thigh and standing straight brings the knee past parallel.

When I tried it on my kBox, it lit my glutes and psoas. Initially, I used a weight that was too heavy. It went to my quads and was ineffective. I called the guys at Exxentric and asked them to build me a very small plate so my body would not cheat. Two weeks later, I received a package from Sweden with a tiny kBox plate. (Thanks Erik and Andreas! Great customer service! Something lacking from some other companies mentioned in my other posts.) The tiny plate rocked it. My glutes were burning after a set and the psoas was jacking my knee up. When I stepped off the machine, I felt like I could fly. Awesome! I tried it with some rubber bands. Not as good. It doesn’t have the eccentric pull that the kBox has, which seems to really fire the psoas.

What does this have to do with ground force? If the psoas and glute are reciprocal functioning mechanisms, the glute will work better if the psoas is firing. And, since the glute is in its peak contraction at the midstance phase, we are strengthening this pattern where we need to. Timing is half of sprinting. But in the weight room we never work on that. Now we are.

Asafa Powell and Usain Bolt
The two best. Do they have huge rectus 6-packs or huge psoas underneath that push the 6-packs out?

 

 

Two

The second exercise is a reactive single leg squat. We challenged the push of the swing leg knee with our kBox psoas lift. Now we will weigh down the stance leg. I use my Hammer Strength deadlift, but dumbbells work well as do rubber bands—or any combination of the three. The athlete picks up the weight and does reactive quarter squats up to his big toe. To work on timing, the swing leg will come high. And the top of extension, the athlete will rapidly drop back down and repeat.

The keys are an ankle bend into a rocker position and a slight hip bend so the glutes and hamstring will need to extend. I usually hook my micro-muscle lab to the bar to monitor force output but it died on me. The Gymaware people don’t respond to emails so I am waiting to hear back from them so I can get back to measuring. I have been measuring this output for years and my fastest runners are the ones who put out the watts. It never fails. I usually vary between 45-135 lbs. After that the power output drops.

 

Three

The third exercise is kickbacks on the Shuttle MVP. Now we are leaving the ground. I adjust the weight to less than body weight for weaker athletes so their contact time is quicker. I weigh down stronger athletes and really force them to hit the plate hard. Some athletes like to be face-down and others on their side. I don’t put them on their back because foot placement is too far in front. No Shuttle? No problem. Hang some rubber bands from the ceiling or the top of a squat rack and do French Contrast jumps, a la Cal Dietz. Again, the body weight can be controlled by the strength of the band.

 

Four

The fourth exercise ties everything together. We call it Boom Booms because I want to hear the foot punch the ground. The second boom comes if we want to do two contacts to the ground. I stole it from Frans Bosch’s Running DVD (I stole a lot from that DVD). Athletes start with a butt bungee around their waist and walk out to tighten the band. This gets more glute function, though I have no proof other than feel. They lift their swing leg and arms to a perfect position. Quickly they step down with the swing leg, scissoring their legs. The swing leg hits the ground and punches back up to the starting position.

In his book, Melén shows the positions of where knees pass each other in a variety of sprinters. The faster the athlete, the further away from the ground the knees pass. From the picture, you can see that there are different surfaces on the floor. I want them always changing the surface. Sometimes I put 5-pound plates under them to make them uneven. There are lots of variations to this exercise that we use but I will cover those on my forthcoming warm-up and lateral chain articles.

 

Five

The last exercise is a fly 10. We do 2-3 to warm up and get a top time and then start to cycle through the exercises. The kBox is great because I can take it out to the track and do kickbacks and single leg squats with it to try to replicate the full indoor workout. The athletes usually feel great when they run and the neural drive for the exercises sometime coaxes some really good times, even after they are fatigued. When their times slow more than 5-6%, I stop them. It is usually 2 cycles.

This is a great workout because it kills two birds with one stone. The athletes get a “weight room” workout and sprint together. I think one of the biggest barriers for high school athletes today is doing too much. Dawn patrol workouts, breakfast club, Animal farm, etc. before school and sprinting after creates a horrible recovery situation. It is just way too much. And it is not just their coaches. It is them too. They will sneak off to Lifetime Fitness to get more in and the body, both neurally and muscularly, never gets a chance to recover. I see it every year. The ones who don’t get better do too much. I see when I muscle test as well. I am sure the Omegawave and Bioforce people are tracking that also. Rest is a workout and drugs are not an option for the people I train.

When I used this workout extensively, my athletes had their best fly 100 times and ran some of the fastest times in Illinois history. Why did I get away from it? I get bored like you do. I constantly look for new stuff when I already have all that I need in front of me.


Here are some ideas I play with. Maybe something to them, I don’t know. The second to last one has John Fox pulling over my 4-way hip machine. That is some power.

 

Sprint Relay Team

We all have groups of student/athletes who we hope we can change their lives. Sometimes you have a group that changes a coach’s. This group ran 41.84 and 1:26.06, two of the fastest times in state history. (From left) Tarrance Williams, who graduated from Eastern Illinois. You all recognize him as the Eastbay catalogue model. Jimmy Sullivan threw the javelin for University of Illinois, spent a semester in Patagonia in National Outdoor Leadership School, and then walked across South America. John Fox ran at Illinois, but his career was curtailed with a recurring hamstring injury. He is enrolled in law school. Khara Williams is currently breaking into a career in theater.

This is another group of athletes. The first one is a long jump state champion and all-state 100m. The second is a girls all-state 400m runner. And last is a good high school sprinter who ran 11.4 FAT.
