XPE Combine

5 Takeaways from Combine Training at XPE to Use at All Sport Levels

Blog| ByMark Hoover

XPE Combine

The NFL Combine is an annual event where prospective draftees look to make the jump from college to professional football via the NFL Annual Player Draft. This weeklong experience allows the Draft prospects to showcase their physical and mental abilities to team officials, who use it as the final piece in developing their Draft board. The athletes typically spend the months leading up to this showcase preparing themselves for the very specific testing they will face. The majority of these athletes will select one of many facilities across the nation that specialize in Combine preparation.

For those unfamiliar with Tony Villani and Matt Gates, they operate one of the nation’s most successful NFL Combine training facilities, XPE Sports, in Ft. Lauderdale, Florida. It isn’t the fancy, high-tech facility you may picture when you think of “Combine Prep.” What is XPE? It’s a high-energy, high-performance facility that, year in and year out, produces the best performances the NFL witnesses at its yearly Draft Combine. Unlike many other facilities that work with Draft Prep athletes, XPE does it with a much smaller number of athletes to keep the trainer-athlete ratio low.

The chart above, taken from a Matt Gates tweet, shows the 40-yard dash event success XPE had in 2022, with only 8% of the total athletes at the Combine being trained at their facility. Needless to say, when you visit XPE during Combine Prep time, you see the world’s best Combine Prep coaches working with some of the best athletes in the world.

I spent two days at XPE during Combine Prep period. To say what I experienced was anything short of amazing would be an understatement, says @MarkHoover71. Share on X

I was blessed to be invited to spend two days at XPE in early February during the midst of the Combine Prep period. To say that what I experienced was anything short of amazing would be an understatement. I walked away with a much more in-depth perspective of what happens inside this “speed laboratory.” While I left with many more details, I wanted to outline my top five takeaways from this eye-opening experience.

1. Combine training is not football-specific training; for the most part, it is task specific.

Obviously, there are football-specific drills being done during this time. However, what jumped out at me during my short visit was how those take a back seat to the preparation for the specific tests the athletes will be evaluated on.

One of the first conversations I happened to eavesdrop on gave some insight into this—a position coach (who may have been employed either by XPE or an individual athlete) was pushing for more on-field skill work. This may not seem like an unusual request at face value—within the landscape of a precision work/rest to peak performance schedule of a high-performance facility, though, it is a potential issue. Everything is scheduled and accounted for in the XPE performance model, including:

  • Training
  • Rest and recovery
  • Nutrition
  • Physical therapy

Adding more stress to this could potentially impact the detailed and very task-specific preparation plan.

“Our process takes precedence this time of year,” was the response. “They won’t lose their ability to play football in six weeks.”

The reality is that these athletes are not there to be better football players—while football specific-drills have a place during Combine Prep, the sole purpose of this once-in-a-lifetime preparation period is to prepare for the best performance possible in each of the Combine events. I heard Tony tell his athletes, “This will be the most important and most likely last 40 you will ever be timed in.” The scouts and coaches have watched film: they know what each player is capable of on the field. Draft status—and the financial potential that comes with a top-notch performance—are the primary goals during this period.

XPE Training

As an athletic performance/development professional who works with student-athletes at the high school level, my personal takeaway was that we have to recognize there may be times that we must make training adjustments based on things the athlete may face, even if it’s outside of our comfort zone.

A sports coach may demand performance on a conditioning test that we see as pointless or misused. But if the athlete will be judged by it, we need to put aside our bias and do our job by preparing the athlete for it. Most recognize that the best Combine performances are often achieved by players who end up not being good enough at the game to make it in the League. Still, if the gateway to entry is a 40 or a timed 18 100 test, our job is to give the athlete the best possible preparation for it.

2. The level of speed and quickness compared to a high school or college training session is eye-opening.

This sounds like a “thank you, Captain Obvious” statement. And I absolutely 100% expected to see a significant difference in the speed and quickness of potential NFL players compared to high school or even the average college-level player. But the reality of it gave me chills.

When we have an athlete at the high school level run a 4.5 laser-timed 40, it’s a huge moment. We celebrate it, and rightfully so. The number of combine prep guys that ran past me at 4.5 or above (to quote my friend Cody Hughes, who also spent time at XPE this year) “could be counted on one hand.” I’ve never been to a NASCAR event (and I am not a fan), but my friends who go to the races live will say, “The speed and sound the cars make as they pass by give you chills.”

Standing 3 feet or less away from this group of Combine guys as they flew past—you can feel a true 4.2 or 4.3 guy as he passes. The pure force they put out also has a different sound than anything I’m used to. When we sit in the stands or watch these guys on TV, we are watching the top 1% compete against the top 1%. The difference between this level of athlete and what the ordinary high school coach sees on a daily basis is massive.

While the speed and size of these guys were notable, one thing really separated them from the vast majority of athletes I have worked with: not only the sheer force and power they put into the ground as they take their initial steps (linear or lateral steps) but also the force behind their limb movement. No rolling start, long build-up, flailing arms, or less-than-optimal range of motion. These guys PUSHED and ripped through the start, and it shot them by me like they came out of a cannon. Not just once in a while, either. Every single rep, everything they did.

If I could bring any message back to the athletes I work with, that would be the main one. Put force into the ground with the proper angles and mechanics, and let physics do what it does.

Coming from a high school coaching perspective, another observation I shared with one of the XPE guys was the difference it would make having just ONE of these types of athletes on your high school team. There’s a lot of talk on social media about what type of impact a coach has on wins and losses at that level. While I am not downplaying the importance of coaching, if the school you coach at produces even one player of this caliber per year, you will be a pretty good coach, regardless. If you play against these types of guys, you better have some to match. Otherwise, you may be the best coach in America and probably still won’t win.

3. Watching the current NFL players train with the Combine guys allows you to see what professionalism is.

XPE has turned out a long list of Hall of Fame and high-level NFL performers. While I was on-site, I was able to see several current and former NFL players either working in the drills or actually leading them. While they are all incredible athletes (obviously), one characteristic stood out more than anything: the level of “professionalism” with which, to a player, they all carried themselves.

From one of the NFL all-time reception leaders to the All-Pro Caliber player all the way to the practice squad member or USFL star I was able to observe, they all had “it.” How would I define “it”? That’s tough to put into words, but my biggest takeaway was that “it” is characterized by intense and obsessive attention to detail during training.

I’m sure plenty of great athletes may not have “it” and are talented enough to still be great. The guys I saw at XPE? It was an across-the-board characteristic. Their focus on being in the moment and task-oriented was incredible to see. When they realized they missed a step or did something they didn’t mean to do–whether a coach or other player called them out or not—they self-corrected and refused to take a bad rep. It was inspiring and made me wonder what a force multiplier that would be if high school coaches could somehow make that a more common occurrence at our level.

Villani Gates

This also helped me look at the Combine and really see who was ahead of the game and already shared some of those characteristics. I noted a few and asked the staff about those particular guys. They ranged from a potential first-round pick to a couple of Pro Day guys who are long shots. The one common characteristic was that the XPE staff regarded each as a guy who would likely exceed their Draft Day potential and probably play well in the NFL.

I saw the power of Anquan Bolden and his effect on the younger athletes as well. When he spoke? They listened and took everything he said seriously. It was awesome to see him pouring his knowledge into these guys.

Yet another force multiplier at our level is allowing more experienced athletes to step in to teach the less experienced ones. This model of giving back should be standard practice at all levels. Share on X

It also reaffirmed the power we have as coaches—we have the ability to stack that type of learning in our programs, whether it’s having a star varsity athlete teaching our youth players or a college/NFL alumnus coming back to do the same with that star varsity player. Yet another force multiplier at our level is allowing the more experienced athletes to step in to teach the less experienced ones. Our voices are heard daily, for years. This model of giving back should be standard practice at all levels.

4. The areas where performance breaks down from a technical standpoint are common across levels.

Believe it or not, this is not much different for most of the Combine or even NFL guys than it is for the high school athletes I work with. The reaction to the coaching tends to be a bit different. The level of self-organization to improve based on experience does too. But the performance breakdowns, such as poor foot placement, improper mechanics, less than optimal movements, etc., seem to be the same across the board.

For example, at one point, a current NFL player and four middle school players were working on eight-vector cuts: 45, 90, 135, and 0. Tony coached up the same initial mistakes from all five. Of course, the speed and power taking place were vastly different, but as an example, the NFL guy and the 13-year-olds were all stepping too far outside their body on the 45-degree cut when the drill began.

The drills the group did to prepare for a laser-timed sprint also sounded a lot like the drills at my school (at least initially). “Put force into the ground” or “force into form” are cues I heard at XPE as well as when I returned to my coaching job later in the week.

Also, while I was there, I was told there was an athlete who could be great, but “They don’t push themselves enough, and it hurts them.” Sound familiar to everyone who’s ever attended a middle school or high school workout? Probably.

One common factor exists with every athlete, from the youngest you work with to the 13-year NFL vet—they are still not a finished product, says @MarkHoover71. Share on X

The bottom line is that one common factor exists with every athlete, from the youngest you work with to the 13-year NFL vet—they are still not a finished product. This is an important point that I brought back to our athletes. If Courtland Sutton is still working hard to be a better player, then there is no excuse for us to believe we have achieved all we can as athletes while in high school.

Another thing that leaped out at me was how many of these high-level players struggled with some of the most basic movement skills compared to others in their group. I’m fairly certain this is because their pure athletic ability was enough at their previous level, so they could get away with neglecting some of the basics. Many of these guys were so athletic that worrying about the small things seemed redundant. It got me thinking about what would be possible with a team of athletes for whom, regardless of talent, basic movement skills were the priority. I think that thought alone could be a powerful tool for any high school coach who would choose to embrace it.

5. Your athletes are not always entirely YOUR athletes.

This is a well-known reality for all high school coaches—we deal with athletes being pulled in all directions. Club coaches, parents, sports coaches, private trainers…the list goes on. I didn’t realize until my visit how much of an issue it was even at this level.

The trainers and coaches preparing athletes for a chance to play at the premier level of their sport still deal with private coaches pulling athletes into their sphere of influence. They also have position coaches (as stated above) who are anxious to get their influence in. Then there are agents and (believe it or not) parents or friends…and they all want to have their input. While I was at XPE, an athlete who had been contacted by a private skill coach during the Combine training decided to do extra sessions outside of the XPE world. That private trainer blasted it on social media, which luckily alerted the XPE crew and the player’s agent, both of whom made sure the athlete knew what a bad idea it was.

Just like we, as high school coaches, are not really able to order the kids not to play club during a varsity season or not to attend a personal trainer, etc., this remains just a strong suggestion even for this level of athlete. In this case, the athlete understood what was at stake, but often our athletes either don’t buy into what we say on the issue or don’t care. That’s just part of the landscape. However, the diplomatic, fact-based discussion that was had showed us a very important lesson: We can’t force athletes to stop doing these things; we just have to do our best to educate and inform about the potential adverse outcomes of working outside the plan.

The Most Important Takeaway

The most important takeaway of spending a few days with elite trainers preparing elite athletes to play an elite professional sport? It was how much I learned from being a fly on the wall that I could bring back to my athletes.

The things I was able to add to my toolbox that will benefit the players I work with were numerous. It was an eye-opener for me, to say the least. Obviously, there will be a curve as to how I will use the exact methods when working with a younger level. However, the basic principles that XPE uses to help their athletes blow the doors off the Combine every year are the same.

I would encourage you to get to know Tony, Matt, and the rest of the XPE crew. Seeing them work their craft was truly a thing I will never forget. From the warm-up to the guys hitting PRs on the ShredMill and transferring those to insane fly 10 times, it was an amazing experience.

Cardio Minute Intervals

Keep Your Cardio Simple with Minute Intervals

Blog| ByCole Hergott

Cardio Minute Intervals

Too many people complicate their conditioning work and intervals by trying to get their athletes into the “fat-burning zone” or train at their lactic threshold, etc. The only thing is, those will be different for different people, and each prescribed interval session has a different effect based on how fit your athletes are at the time.

As a university strength and conditioning coach, I have to write conditioning programs for six different sports (12 teams). I dove into the research, read many books on the subject, and thought I was an expert in cardiovascular health and improvements. Then I tried to apply these specific protocols with the different teams, hoping each team would increase their fitness to the specific level required by their sport.

Do you know what happened?

Not that!

The prescriptions were too confusing and too hard to follow. I tried individualizing their conditioning work using the Maximal Aerobic Speed (MAS) protocol by basing their distances and interval times off their most recent fitness testing scores (Yo-Yo, mile run, Bronco, etc.). Most athletes didn’t do the workouts at all or just went for a 5-kilometer run instead. So, after all that hard research (which is great knowledge to have moving forward), at the end of the day, simplicity wins (Keep It Simple Stupid—KISS). Shocker.

At the end of the day, simplicity wins. I now prescribe minute intervals as conditioning for both my athletes and my non-athlete clients, says @chergott94. Share on X

What I have settled on now, especially in-season for our athletes as a measure of top-up to their fitness levels, and what I prescribe to all my non-athlete clients are minute intervals. Short, to the point, and deadly.

How It Works

There are three protocols.

  1. The first is very high-intensity work with longer rests (anaerobic alactic). The athletes push as hard as they can (maximal effort) for 10 seconds. Then they rest for 50 seconds (the remainder of a minute) and repeat for the number of sets you want for them (more on that later).
    • I recommend most of my teams hit the bike for this sort of protocol, as they can push harder on a bike than if they were running outside or on a treadmill. Regardless of sport (rugby, soccer, basketball, etc.), it gets them off their feet and hammering the intervals as hard as they can.

  1. The second is high-intensity work, but starting to hit that lactic feeling in their legs that many sadistic folks crave. They push hard for 20 seconds and rest for 40 seconds. Repeat for the number of intervals you want.
    • These are really easy to run in a shuttle fashion. I often get my athletes to set a distance (e.g., 10 meters) and run back and forth as many times as they can in that time. That way, they get some change of direction work, reducing hamstring injury risk (instead of sprinting all-out for 20 seconds in a straight line).

  1. The third session is for sure giving them jelly legs as they push moderately hard for 30 seconds, then rest for only 30 seconds before repeating. So, the work isn’t as high as the other two, but the rest is shorter to compensate.
    • I recommend my teams hit the bike, or they can shuttle these as well. These intervals could also be done as hard tempos, but once again, for the sake of the hamstrings, a shuttle is best (e.g., 10m–20m) or hitting the bike.

As you can see, each interval adds up to a minute (hence the name). I love these intervals for many reasons, but the simplicity of the timing is great because even if the athletes don’t have a timer app on their phone (which everyone does nowadays) or they forgot their phone altogether, they can simply look at a clock, watch, etc. and easily keep track of the time.

Second, they can do these on any equipment they have—rower, bike, treadmill, stair climber, jog outside, shuttle runs, etc. Any and all modes of cardio equipment will get the job done. As mentioned before, having athletes hit the bike allows them to push harder, which is more beneficial for the 10:50 protocol while also reducing the joint stress for impact sports (soccer, rugby, basketball).

Sprinting is good for conditioning and is obviously more “sports-specific” for running sports. Still, as mentioned above, I recommend putting these into a shuttle format so that athletes aren’t just all-out sprinting for 20–30 seconds (which would be close to 200 meters). This will reduce hamstring injuries for sure, and if there is one thing we all know, if an athlete gets hurt doing your conditioning work, that is bad news for you!

Next, these minute intervals are very easy to start with for programming. As for the specific number of intervals, I usually start my athletes off with 10. It is a nice round number, and that also means it only takes 10 minutes to complete (which doesn’t sound that intimidating until you are four intervals deep and have six to go). Another reason I love the simplicity of the format is that the athletes can just do as many intervals as they have time for. If they only have five minutes to hit conditioning after their lift, they just do five. It’s as simple as that!

Lastly, progressing the intervals is a very straightforward process. An easy way is to simply add a rep each week or so. So, week one, you do 10, week two, you do 11, and so on.

TrainHeroic Intervals
Figure 1. One-minute conditioning interval workouts prescribed to athletes via TrainHeroic.

You can also play around with which option you prefer based on their training schedule. If they do their conditioning work three times a week, you could do the 10/50 on Monday, 20/40 on Wednesday, and 30/30 on Friday. Boom! Simple.

Now, if they only do conditioning twice a week, they could still rotate through by hitting 10/50 on Tuesday, 20/40 on Thursday, and then 30/30 on the following Tuesday. This would lead them back to the 10/50 that Thursday. That way, they still hit all three interval sessions, but they are just spread out more.

Which Methods Is Best for Me?

This is a question I often get asked by my athletes and clients; as always, the answer is that it depends. Primarily, it depends on what area of their fitness is lacking the most for your athletes individually.

  • Do they get tired easily at the beginning of a high-intensity shift or play? Then maybe ramp up the 10/50 protocol, so they have the alactic capacity to push each time.
  • If their legs get that burning feeling after only 10–15 seconds of work/play? Then give the 20/40 a go to try and push that feeling until later so you can perform more optimally longer by pushing your lactic threshold a bit higher (increase lactate clearance ability).
  • And lastly, if they find that halfway through their shift or by the end of the shot clock they are gassed, then the 30/30 will help with that by increasing lactic tolerance. (Because after a hard 30 seconds, it will build up, but we want to make sure they can push through it.)
As you can see, there are many options for progress and variability with the minute intervals, which is why I like the method so much, says @chergott94. Share on X

As you can see, there are many options for progress and variability with the minute intervals, which is why I like the method so much. At the end of the day, each of these will give your athletes a killer session—they won’t enjoy them much (sorry), but they will give them the fitness levels and cardiovascular gains they seek.

So pick your modality, pick your option, and get after it!

Peace. Gains.

Boo Shexnayder

CVASPS Seminar Q&A Series: Boo Schexnayder

Blog| ByJay DeMayo

Boo Shexnayder

I’m so excited to be welcoming Boo Schexnayder back to The Seminar this July—his presentation at Union Fitness last spring on return to play was fantastic, and this year we’re bringing him back to talk about what many would say is Coach Boo’s bread and butter: how to make athletes faster. His resume is second to none and only eclipsed by how great a person he is and how willing he is to share to help coaches get better. I hope you enjoy our conversation.

CVASPS: What are a handful of the mistakes you routinely see made by strength and conditioning coaches in the United States and around the world, and what specifically do you feel should be done differently to correct these issues?

Boo Schexnayder: I am hesitant to make critical statements about a profession in general, but I think there are some directions that S&C coaching culture has taken us in that can be improved. First, we have yet to move from a muscle-based model to a neural-based model.

There are some directions that S&C coaching culture has taken us in that can be improved. First, we have yet to move from a muscle-based to a neural-based model, says @BooSchex. Share on X

These athletes are talented not because of the characteristics of their muscles but because of the effectiveness of the nervous system in activating muscle—and few of our training constructs are designed with improving recruitment and rate coding in mind. As a result, speed and power are very misunderstood, strength training is not quality-based, and rehabilitations take far longer than they should. Knee-jerk reactions to new technology and research also produce an array of problems.

CVASPS: What advice would you give a coach to improve their knowledge as a process of continuing education? By which I mean, can you point our readers in a few concrete directions to find the scientific and practical information to improve the methods used to improve performance?

Boo Schexnayder: I feel strongly that mentorship may be the most productive means of professional improvement for young coaches. While it does limit the diversity of viewpoints you are exposed to, it’s a good way to get into the ballpark quickly as a young coach. I think it’s important to recognize that 5% of your training program should act as a working laboratory because the answers you find on your own are always the most meaningful.

Lastly, all professions, including ours, tend to become inbred. We talk to each other too much and fail to reach outside the commonly accepted boundaries of our professional coaching culture into other fields. I think there is a lot to learn that can be applied by studying other sports, the medical and therapy fields, psychology, philosophy, engineering, history, and so many other fields that would view our problems and potential solutions in an entirely different light.

CVASPS: For readers unfamiliar with your history, can you provide some background on your niche in the world of athletics, the educational/career path you took en route to your current role, and any notable publications, courses, or products you have available that you’d like to direct readers toward to dive deeper?

Boo Schexnayder: I started as a high school coach, coaching football and track, and eventually moved into collegiate track coaching, coaching a year at Blinn (Junior) College, three years at Southwestern Louisiana (now Louisiana-Lafayette), and then 13 years at LSU. During that time, I had a good bit of success turning out winning athletes at the national and world levels. I was fortunate that my success opened some doors for me, so I also became very involved in clinics and coaching education and began working with potential NFL players in Combine prep.

I left LSU in 2007 and continued international-level coaching and coaching education projects, and I began consulting in various sports and levels. I returned to LSU for another five-year stint as strength coach for track and field in 2017 and retired from the university in 2022. I continue to do a lot of clinics, write a lot of curricula for coaching education programs, mentor lots of younger coaches, teach coaching education courses, and perform consulting work for many NCAA programs, professional sports teams, and a few foreign countries. I operate a website, sacspeed.com, where you can read articles I have written and learn more about me and the materials I have to offer.

CVASPS: Can you provide a sneak peek at the topic you will be covering at The Seminar and a few valuable takeaways on the presentation for those who may not be able to attend?

Boo Schexnayder: The topic is “Critical Factors in Speed Development.” I plan to get very detailed about speed/power development programming. I think 75% of athletes never reach their genetic potential for speed, and I’ll explain why. I’ll look at effective speed training practices and the common programming mistakes we make. Speed development training is generally undervalued as far as the way it increases the effectiveness of the strength (and other) programs, so we’ll examine speed training not only as a way to get faster but also as a way to increase the overall effectiveness of the program.

(In my session at The 2023 Seminar) I’ll examine speed training not only as a way to get faster but also as a way to increase the overall effectiveness of the program, says @BooSchex. Share on X

I’ve also observed over the years that many coaches design effective speed training that looks great on paper but doesn’t work well. Speed acquisition doesn’t happen because other portions of the program are set up in an incompatible way. I’ll go into detail about how to avoid these common mistakes. We’ll even touch on how these philosophies can be applied in the rehab field.

CVASPS: I hope you enjoyed this brief look into the thoughts of Coach Boo and understand why I’m so excited to have him back on the docket for The 2023 Seminar. Join us at PLAE HQ in Canton, Georgia, on July 21 and 22 for what is going to be an absolutely fantastic event.

Kinvent Force Plates

Kinvent KForce Review: What’s Changed

Blog| ByVien Vu

Kinvent Force Plates

Force plates have been growing in popularity in the performance and rehabilitation world due to their unique metrics that may inform player safety and preparedness. Their popularity has expanded beyond research labs now that well-known companies like Vald and Hawkin Dynamics have integrated software to make the user experience much more approachable. Kinvent is newer to this market.

At the end of the day, all force plates measure force; there are, however, little nuances with software that may make one brand desirable over another based on preferences and operations, says MuyVienDPT. Share on X

Kinvent is an interesting addition in the sense that it began with a clinical approach to its software and hardware. In contrast, brands like Vald started from a performance-driven perspective and just recently branched out to the clinical side with Vald Health. Yes, at the end of the day, all force plates measure force; there are, however, little nuances with software that may make one brand desirable over another based on preferences and operations. This review will give you an idea of what to expect with the Kinvent KForce plate and help you decide if this is the right purchase for your current operations.

Technical Specifications

The elephant in the room cannot be ignored: you cannot perform jumps on KForce plates. Due to reports of calibration, collection, and syncing issues with the generation 2 plates, the company removed the feature for new users. If prior users with the function attempt to jump on them, the company won’t cover any damages or malfunctioning of the plates caused by the jumps. Although the company offers the more expensive Delta force plates, the removal of the jumping ability still leaves users with more to desire, given that the company sells a “jump frame” for these force plates and more than doubled the load capacity. If these could handle jumps, these would be a bargain at the current price range (as were their generation 2 plates before all the issues).

Because of the inability to assess jumps, I don’t recommend KForce plates for performance coaches or rehab specialists in high performance. However, they do perform well for the majority of rehab specialists and fitness specialists who find data from stationary movements valuable.

Given its relatively low price, these third-generation KForce plates offer a good middle ground for those looking for a device to measure non-impact forces, balance, and weight shift. Share on X

With the removal of jumps, it is hard to decide whether to compare these to force mats or force plates (figure 1). They are cheaper than force mats, yet more practical and applicable, but they are less useful than their more expensive competitors. Given their relatively low price, they offer a good middle ground for those looking for a device to measure non-impact forces, balance, and weight shift (figure 2). However, the customer must determine whether they desire that middle ground.

Force Plate Models

The removal of the jump assessment is a large disappointment—however, users can still utilize the increased load capacity with isometric mid-thigh pulls. Their previous load capacity was not high enough for elite athletes and was not at the standard capacity of their competitors. Additionally, their sampling rate is now as high as competitors, with an upgrade from 75 Hz to 1,000 Hz; 1,000 Hz is recommended for human movement assessments.1 Kinvent suggests the sampling rate can be programmed up to 4,000 Hz; however, most users will not need that high of a sampling rate.

Cost

Kinvent’s battery life continues to be legendary, and they have upgraded it from the generation 2 force plates. To give an example, I’ve heavily used the generation 2 force plates for nine months and only had to charge them twice. The batteries never completely ran out, either.

These generation 3 force plates carry on with this trend, as no charge has been required for more than a month. USB-C ports have also been added, which is very welcome since most devices use the same cord. The package arrives with two charging cords; however, users in the United States will have to purchase the standard United States outlet adapters.

The biggest complaint with the generation 2 force plates was their inability to sync consistently. Errors occurred several times, with one or both force plates losing sync with the tablet before, during, and right after tests. This was extremely frustrating, as users were advised to reinstall the app, restart the plates, recalibrate the plates, or even all of the above. This is not good when you have lines of athletes waiting to be tested or a busy clinic full of patients who need your attention, or you need to keep reps consistent for research.

Users also had to completely close and re-open the app to test a new user because the force plates would not sync once one user was complete. All that negative feedback led the engineers to focus significantly on the device’s connectivity, and generation 3 units are much improved in that area. An app restart is still needed at times when switching between users, and the force plates still lose sync—however, these errors occur far less frequently.

Hardware

In regard to the hardware, the force plates are a great size—they even accommodate size 15 shoes—yet they remain light and small enough to carry in a backpack (figure 3). This makes them versatile for many athlete and patient populations while also accommodating those who may have concierge services or travel to local teams for monitoring and screening.

Force Plate Sizes
Figure 3. Pictured are size 15 shoes on the third-generation force plates. Although they may be perceived as small, large-footed athletes can still perform all the compatible tests without issues.

Although the technical specifications have been upgraded from the second generation, the build quality did not significantly improve (figure 4). The formerly robust and durable surface was replaced with a thinner plastic that does not seem like it can handle impacts over time. The power button was replaced with a rubber button that may be more aesthetically pleasing but is not very pressure-sensitive. Users will have to push the button hard to feel the “click” of the actual button underneath and may sometimes even need to push it with a pen. The LED lights on the top and side remain from the generation 2 version, making it easy for users to see if the plates are on, synced, or charging.

Of note, I evaluated two sets, each made with slightly different materials (figure 4). One came as a part of a kit, and the other came as a standalone set. Overall, the force plates that came with the kit feel more robust and of higher quality. It is undetermined if two different types will exist or if the company will commit to manufacturing just one type.
Comparison

The Software

A short time before the generation 3 release, Kinvent released the K-physio app and discontinued support for their KForce app. The K-physio app is a significant upgrade and is what all Kinvent users will want. It gives you a host of metrics, such as center of pressure, impulse, peak force, and rate of force development at specific time intervals. The software comes with three different options. The starter package is the best option for KForce users since it gives you access to the most popular tests that these force plates can measure.

The software provides great data visualization, and you can easily save test results to a customized PDF, depending on the software package purchased. This is a nice feature, but it has room for improvement given that competitors allow users to customize exactly which metrics and groups to show/hide—this is important when data is delivered to stakeholders.

While they offer a web platform for desktops, it is lacking (figures 5 and 6). Users who access their data will be missing out on 90% of the mobile app’s functionality. Among the missing features at the time of this review are inabilities to:

  • Delete test sessions.
  • Edit users.
  • See advanced metrics (for jumps).
  • Customize reports.
  • Make/sort groups.

Most importantly, there is no ability to administer a test.

The desktop app does not pick up or allow the entry of participants’ demographic info. This hinders the daily operations of rehab specialists who need to document and multitask on their laptops.

Training on these plates is a strong point since they offer excellent games. Karl the Kangaroo is their mascot, and the games are goofy enough to get anyone smiling and competitive about it. Users can adjust the difficulty, amount of anteroposterior weight shift, and amount of mediolateral weight shift. I’ve had more than dozens of postoperative athletes, within and between session changes to squat weight shifting, who have been quick and effective with these games.

Lastly, the software is fast-evolving, and Kinvent’s developers seem to release a fix or brand-new feature each month. Although there could be improvement based on the above summary, the software team acts quickly and will likely enhance features even more after the publication of this review.

Score: 7.5/10

These force plates were made for those in clinical settings who, at most, want to measure squatting, balance, and isometric strength objectively. The build quality leaves much to be desired compared to Kinvent’s previous iteration. Still, the new hardware brings technical specifications up to date with their competitors at a relative bargain price.

The software provides and visualizes enough data for users to make well-informed decisions but lacks the advanced analytic functions of its competitors; the desktop version is severely lacking. Overall, I recommend this more for those in a clinical setting, but anyone working with athletes should look into Kinvent’s Delta force plates, Vald’s Force Decks, or Hawkin Dynamics’ force plates, since they offer the ability to test jumps.

Elastic Strength Resilience

Preventing ACL and Achilles Injuries with Elastic Strength Training

Blog| ByKim Goss

Elastic Strength Resilience

(Lead photo by Linda Brothers, LiftingLife.com.)

On December 12, 2022, Arizona Cardinals quarterback Kyler Murray was scrambling toward a first down when he collapsed awkwardly, tearing his right ACL. What puzzled the sports broadcasters was that no one touched him—it was, to use a term we seem to be hearing more frequently, a “non-contact injury.”

It’s one thing for a quarterback to suffer a severe injury when pounced upon by a 300-pound lineman, but how could Murray sustain a season-ending injury just by zigging when he should have zagged? After all, the NFL supports its athletes with elite strength coaches, state-of-the-art training facilities, and eight-figure annual sports medicine budgets. Let’s look at the bigger picture.

Although the numbers vary according to the sport, about two-thirds of lower body injuries are considered “non-contact.” The rest are considered “contact,” involving a collision with another athlete or an external object. Over the past decade, ACL injuries in the NFL averaged about 50 per year, with slightly more occurring during the season. Further, those with a history of ACL reconstruction are more likely to suffer a subsequent ACL injury.

ACL injuries are bad, but Achilles tendon injuries may be the worst. Complete recovery from an Achilles rupture can take a year and may signal the end of a promising career at the pro level. How about some numbers?

On February 22 of last year, the NFL reported 25 Achilles injuries during the season, and players in the Canadian Football League didn’t fare much better. In a 2021 training camp, four players on the Saskatchewan Roughriders team suffered Achilles tendon tears. These were non-contact injuries, and all four occurred in just six minutes! Grass versus artificial turf debates aside, something wrong is going on—and it’s not just in football.

Sports Illustrated
Image 1. In 1986, Sports Illustrated reported on the NFL’s disturbingly high rate of injuries. Devastating injuries to the knees and ankles are still a concern.

As with the NFL, NBA superstars enjoy an entourage of support from their strength coaching and sports medicine resources. Still, the NBA’s rate of lower extremity injuries has not decreased significantly in the past dozen years, despite the emphasis on three-point shooting where there is less contact (and that fuels the Jordan vs. LeBron debate!). Consider the Golden State Warriors.

In the 2019 NBA season, many sports commentators believed the Warriors would repeat as champions. However, Kevin Durant pulled a calf muscle, then injured his Achilles; DeMarcus Cousins, who joined the Warriors while on the mend from an Achilles tear, tore his quad and then his ACL; a tender Achilles hampered Andre Iguodala; and after injuring his hamstring, Klay Thompson tore his ACL! And that’s just one team!

Between 1995 and 2007, the NBA reported four Achilles injuries. In 2019, there were six in a single season! Share on X

On a larger scale, between 1995 and 2007, the NBA reported four Achilles injuries. In 2019, there were six—again, in a single season! Adding injury to injury, before the 2021 NBA playoffs, the league’s premier players missed 370 out of 1,944 games. Although a lot of roughhousing occurs during NBA games, basketball is still considered a non-contact sport.

I’ve been focusing on men’s sports. Let’s now take a deep dive into women’s sports.

Risky Business: The Female Knee

A study published in 2021 concluded that “there are approximately 200,000 to 250,000 ACL injuries that occur in the United States annually, a rate that has doubled over the last 20 years; and this rate has been increasing by a rate of 2.5% annually in the United States.”

Breaking these numbers down in terms of gender, researchers have found that “the relative risk of ACL injury in women is 3 to 8 times greater than males.” The numbers for several women’s sports are so bad that many parents forbid their daughters from ever playing them! Unquestionably, the No. 1 sport parents are concerned about is soccer.

One study reviewing 793 articles found that female soccer and basketball players were about three times more likely to tear their ACL than males. Another study suggested that sport skill level was not the primary issue, as it found that female college soccer players were significantly more susceptible than high school players to injuring their ACLs. The question appears to be not if a female will get a non-contact injury from playing soccer but when?

One straightforward solution to reducing injuries is not to specialize in a single sport. In a 2017 study involving 1,544 high-school-age athletes (half female), sports specialization was identified as an independent risk factor for injury. Specifically, the researchers found that lower extremity injury was 85% higher for those athletes who played a single sport year-round. Also, the popularity of triathlons in the ’80s has been partially attributed to the high injury risk associated with those who focused on long-distance running workouts to compete in marathons, an event on just about every recreational runner’s bucket list. Just one problem.

One straightforward solution to reducing injuries is not to specialize in a single sport…but is that the only answer—the best way to reduce injuries in a sport is to stop playing it? Share on X

To refine their skills to perform at the highest levels and better their odds of earning a scholarship, high school athletes often play on non-school sports teams year-round. Further, college coaches rarely allow their athletes to play multiple sports, particularly at the Division I level. But, again, is that the only answer—the best way to reduce injuries in a sport is to stop playing it?

Multisport

The Weightlifting Paradox

The extent of non-contact injury problems has led many medical experts and sports broadcasters to throw up their hands and say, “Such is the nature of sports!” and “It is what it is.” If so, how come weightlifters rarely get hurt? ACL and Achilles’ injuries are so uncommon in weightlifting that coaches often go their entire careers without seeing either.

Take a look at the scenes in image three that initially seem, well…horrific. In the top left photo, the female lifter drops nearly 297 pounds across her thighs, slamming her knees against the platform. In the bottom left photo sequence, a 152-pound male lifter drops 392 pounds across his outstretched back leg. In the last photo sequence, an athlete awkwardly loses a snatch overhead, causing the weight to fall on her and twisting her knees and ankles in ways that knees and ankles should not be twisted.

Barbell Impacts
Image 3. These barbell-to-body impacts look bad, but none of these athletes were injured. (Bud Charniga photos)

If you thought the impact of having these massive weights crash on these athletes caused crippling injuries, you would be wrong. All three lifters avoided injury, and such escapes are commonplace in the sport. What’s going on? To find some answers, let’s talk anatomy.

Tendons are not rigid, cable-like structures connecting bones to muscles but can stretch up to 8% of their length. The tendons and ligaments of the foot, ankle, knee, and hip work together as a single biological leg spring. These leg springs can stretch, store energy, and recoil to enhance power. There’s more!

Weightlifting sports scientist Andrew “Bud” Charniga says these tissues possess a “reactive protective mechanism” that immediately responds to unstable and unanticipated conditions by releasing muscle tension rapidly and dissipating and redistributing mechanical energy. This mechanism is active in all sports, enabling quarterbacks to safely zig when they should be zagging. It also works with the upper body.

During an arm wrestling match, when the tension on the opponent with the weaker arm is too high, the arm muscles instantly shut down, and the forearm slams on the table. That’s a good thing. If the weaker opponent continued, muscles and connective tissue could be torn, and bones could be fractured.

Does this reactive protective mechanism work just as effectively in females? Consider the results of a five-year study on 480 women who competed in the week-long European Weightlifting Championships. When you add the training lifts for those who arrived several days before they competed and their competition warm-ups and platform attempts, tens of thousands of maximal and submaximal lifts were performed.

Considering those fragile Q-angles women possess, you would think the medical staff at this competition would have been swamped with injuries and have the European equivalent of 911 on speed dial. However, researchers reported zero hip, thigh, knee, lower limb, or foot injuries. Success leaves clues!


Video 1: Nicole (Patruno) Morales demonstrates the large amplitude, dynamic movements involved in weightlifting that use the elastic properties of the connective tissues. Nicole broke junior New England weightlifting records, and her best official lifts are a 178-pound snatch and a 229-pound clean and jerk.

Now that I’ve got your attention, please be open-minded and consider the following human movement perspective on preventing non-contact ACL and Achilles injuries. It may seem a bit radical because many concepts were introduced a half-century ago, but hear me out.

Non-Contact Injuries, Lies, and Athletic Tape

One popular theory explaining the high number of ACL injuries is poor conditioning. There’s even a name for it: “Exercise Deficit Disorder.”

The term was used in a research paper to explain why some NFL players had an increased risk of ACL injury during the COVID-19 period because they did not display the “enhanced physical prowess and necessary neuromuscular control” to avoid injury. As such, one recommendation I’ve seen to reduce the risk of ACL and Achilles injuries in athletes is boot-camp conditioning drills to prevent excessive fatigue. One college program I’ve read about even hired military personnel dressed in combat fatigues to motivate the athletes.

Other proactive methods that have me scratching my head include movement drills designed to keep an athlete’s ankles, knees, and hips in perfect postural alignment. During one coaches’ meeting, I was presented with some rather odd ACL prevention methods movement for women’s basketball developed by an athletic training group. For example, they said that whenever an athlete jumps for a rebound and grabs the ball, they should drop into a full squat to protect the ACL! Huh?

As for all the unstable “functional” strength training exercises recommended, many seem inspired by Cirque du Soleil and do little but distract athletes from being stronger through conventional methods. I say this because Dr. Michael Jonathan Wahl has extensively researched stability training and found that the brain motor patterns exhibited when performing exercises on unstable surfaces were the same as those on stable surfaces. Dr. Wahl had some strong opinions about the value of unstable exercises in injury prevention during an interview I did with him in 2007:

“Sure, a Swiss ball exercise can be taxing for someone who has never done any exercise before; but get a first-year physics student to explain the disrupted torque on the body that occurs when someone squats 500 pounds, and you’ll see that the entire muscle system has to work tremendously hard to handle that type of weight. When an athlete turns their ankle, it’s often because they are not strong enough to handle the disrupted force of the activity, so why not train to get used to that excessive force using the principle of progressive resistance?”

Wahl Study

For women, research has found that during a women’s monthly cycle, hormonal variations weaken the connective tissues, making them more susceptible to injury. The recommendation would be to alter training loads during each phase of the menstrual cycle, but you have to question the practical value of this advice. Are coaches supposed to chart each athlete’s menstrual cycle and pull them out of practices and games due to unacceptable hormone levels?

Then, there are the shoes. Like homeowners with power tools, athletes don’t buy shoes—they invest in shoes. The athletic shoe market is a profitable business, such that considerable funding has been provided for researching footwear to reduce injuries. For example, a study on foot fractures concluded that narrow cleats with minimal stiffness might contribute to fractures of the fifth metatarsal (i.e., Jones fracture). One extensive review concluded that in studying foot injuries, we need to “measure and record the surface properties and potentially the properties (or at least the model) of the footwear worn by study participants.” Good to know.

Canadian weightlifter Francis Luna-Grenier never got the memo. Luna-Grenier competed in the 2008 Olympics in the 152-pound bodyweight class and currently holds all the Canadian records in the 160-pound class. He is shown in video 2 snatching 286 pounds without knee wraps, taped ankles, or a spine-saving weightlifting belt. And in contrast to the high-priced adamantium-laced tennis shoes endorsed by celebrity athletes, Luna-Grenier demonstrates the stability he developed by performing this lift with bare feet!


Video 2: Canadian weightlifter Francis Luna-Grenier demonstrates remarkable strength and stability, snatching 286 pounds in bare feet.

Among the most common ways to prevent ACL and Achilles injuries is to “stabilize” body parts using athletic tape and other forms of bracing, even if those body parts are not injured! On that subject, consider what could be called “The Curious Case of Mac Jones.”

An article published on August 16, 2021, reported that the New England Patriots quarterback wore a brace on his left knee for “protective reasons,” not in response to an injury. Jones told reporters that the knee being braced was the one he plants with, thus the need for extra protection. “I feel good…just want to make sure I keep it safe,” said Jones. In many game-day and practice photos, in addition to the protective brace, Jones also appears to have athletic tape connecting his shoe to his lower ankles (you know, because you can never be too safe).

Fast forward 13 months and the game with the Baltimore Ravens. On one play gone horribly wrong, 307-pound defensive lineman Calais Campbell fell on Jones, causing Jones’ ankle to twist awkwardly. Jones’s stabilized knee and lower ankle were fine, but the collision resulted in a high ankle sprain. Coincidence?

Perhaps Charniga is on to something when he says that restricting the mobility of one joint interferes with the “reactive protective reflexes” of the connective tissues? How can the athlete’s body react to the complexities of moving about the athletic field; be ready to dissipate or otherwise redistribute the mechanical energy of sharp turns, cutting, accelerating, falling and deceleration involved in pursuit and avoiding pursuit with all this stiffness of muscles, ligaments, tendons and joints?” Let’s keep going.

Perhaps Charniga is on to something when he says that restricting the mobility of one joint interferes with the ‘reactive protective reflexes’ of the connective tissues? Share on X

Strength coach and posturologist Paul Gagné says one of the problems with athletic tape is that it may interfere with the proprioception of the fascia, which is the connective tissue that runs throughout the body. “The fascia contains mechanoreceptors in the tendons and ligaments that respond to stress. Athletic tape may compromise body awareness and affect the ability of the tendons and ligaments to react to excessive tension.” For example, Gagné says he’s seen many powerlifters squat several hundred pounds over body weight using a thick belt and be just fine “but then screw up their lower back when shoveling their driveway because of a lack of proprioception in their core muscles.” There’s more bad news.

Charniga says that if you immobilize an area on one limb, such as with athletic tape, the imbalance may increase the risk of injuring an area on the other limb. One high-profile example of this issue he gave was the injury history of Miami Dolphins’ quarterback Tua Tagovailoa. On December 1, 2018, Tagovailoa suffered a high ankle sprain to his left ankle that required surgery. On October 19, 2019, he sustained the same injury to his right ankle and required surgery. Lastly, on November 16, 2019, he dislocated his right hip and required surgery. Coincidence?

Athletic Tape
Image 5. Knee braces and athletic tape are essential tools in sports medicine, but excessive or inappropriate use may do more harm than good.

Athletic tape and knee braces are essential in many situations, such that athletes sometimes couldn’t train or compete without them. On January 21, 2013, Kansas City Chiefs quarterback Patrick Mahomes injured his right ankle in the first quarter of the game against the Jacksonville Jaguars. He hobbled to the sideline to get taped up, then went back out for a few plays. He returned to run a half-dozen plays in the second half before being taken out of the game.

This was the postseason, so apparently, the risk of Mahomes making the injury worse was worth the reward of being one step closer to the Super Bowl. Final score: Kansas City 27, Jacksonville 20. The following week, Mahomes’ ankle was heavily taped in their meeting with Cincinnati. Mahomes was obviously uncomfortable throughout the game, favoring his ankle. But Kansas City kicked the winning field goal in the final seconds, and the Chiefs earned another appearance in the Super Bowl!

Braces and athletic tape, particularly used as a protective measure in non-injured athletes, MAY interfere with the functions of the tendons and ligaments, increasing the risk of injury. Share on X

The takeaway is that braces and athletic tape, particularly used as a protective measure in non-injured athletes, may interfere with the functions of the tendons and ligaments, increasing the risk of injury. This brings us to training.

The Relaxation Response

Gagné has worked with more than 500 NHL players in the past 40 years, pro athletes in several other sports, gold medal Olympians, and our barefoot weightlifter Luna-Grenier. He says we should turn to neuroscience rather than just looking at muscle contractions to prevent injuries.

Jean-Pierre Roll won the highest awards in neuroscience, and Gagné has applied Roll’s research to strength training and injury prevention. “Roll says it’s the eccentric contraction that codes movement. If I’m a baseball player and throw a ball, an eccentric contraction of the long head of the biceps will decelerate my arm and protect my shoulder and elbow joints. Likewise, when kicking a football, the hamstrings are more active than the quads because of their involvement in the deceleration of the leg.”

The success of Louie Simmons and his Westside Barbell Club athletes attests to the value of using bands in training powerlifters. However, Gagné says bands can adversely affect neuromuscular coding because as the bands stretch, their resistance increases, so the antagonist muscles do not need to contract as hard. Charles R. Poliquin would agree.

About 30 years ago, I asked this legendary strength coach about the value of elastic band exercises, which were becoming popular with powerlifters. He told me that when he was hired to work with the Canadian National Synchronized Swimming Team, there was an epidemic of shoulder injuries on the team. When he asked about their strength training program, he learned they use elastic band exercises. He was able to resolve their shoulder injuries simply by eliminating these exercises. From then on, he referred to band training as “tendinitis in a can.” How about one more example?

In the ’70s, many track and field coaches thought they could make runners faster by having them wear ankle and wrist weights during training. It didn’t work and even made some athletes run slower when they stopped using them. What’s more, the weights created momentum in the arms and legs that was challenging to control, affecting the deceleration of the limbs and leading many athletes to complain of overuse injuries.

Tube Warm Up

Legendary track coach Bud Winter’s motto was “Relax and Win!” It’s true. Sports scientist Leonid P. Matveyev has shown that in dynamic sports, muscles contract faster than they relax in novice athletes. However, muscles can relax faster than they contract in elite athletes. Matveyev’s colleague, sports scientist Yuri Verkoshansky, noted that in speed endurance events such as the 400m and 400-meter hurdles, “the key factor defining and regulating sport results at all stages is the speed of muscle relaxation.”

Elastic bands prolong the time an agonist muscle is under tension, which is precisely what you don’t want. Share on X

This brings us back to using bands with barbells. Bands prolong the time an agonist muscle is under tension, which is precisely what you don’t want. Matveyev said the near-isometric methods (often used by strongmen, powerlifters, and bodybuilders) could create “internal tension” that affects the ability of antagonist muscles to function efficiently. Matveyev referred to this condition as “coordination enslavement.”

Tension Lift

The takeaway is that weightlifting is one of the most effective ways to prevent non-contact lower-body injuries since it enhances the elastic strength qualities of the connective tissues. What if weightlifting is not an option? Let’s explore some alternatives.

The Fast Eccentrics Solution

If you don’t know how to teach weightlifting or don’t have the equipment or facilities to perform these lifts safely, you have other training methods available. One of these options could be referred to as “fast eccentrics.”

The textbook Supertraining by Verkhoshansky and Mel Siff, Ph.D., was published in 1993. It was here that they introduced a concept they called “the triphasic nature of muscle action.” They said that all athletic movements contain three types of contraction: eccentric, isometric, and concentric. Their message was that knowing the qualities of each type of contraction should influence how strength coaches and personal trainers should design workouts.

I first met Siff in the early ’90s and wrote many articles with him. He expanded on this concept by telling me about the value of performing exercises emphasizing rapid eccentric movements. One such exercise was a large-amplitude squat jump characterized by a fast eccentric motion with a slight bounce out of the bottom: full knee extension is not emphasized, and you only elevate a few inches off the floor (video 3). Note the emphasis on “large amplitude.”


Video 3: Dynamic, large-amplitude squat jumps and assisted split squat jumps enhance the elastic qualities of the connective tissues.

Charniga says performing exercises through a large range of motion is critical to keeping connective tissues healthy (again, the example of injury-free weightlifters). Consider that, in one research study, surgeons who repaired ACL tears found that the tissues being repaired often showed signs of long-term damage before the tear. The damage predisposed the ligament to injury, acting like a frayed, old rubber band that can easily snap. This finding suggests that exercises performed by today’s athletes (such as partial range squats?) may increase the risk of ACL and Achilles tendon tears.

I’ve used many variations of these exercises with my athletes over the years, particularly figure skaters and sprinters. About 14 years ago, I was a volunteer strength coach for a girls’ weight training class at a high school in the Midwest. That first semester, the primary athletes attending were basketball players, and the coach told me she had to spend 45 minutes before every practice taping ankles.

Before the end of the semester, the coach told me she didn’t have to tape anymore, and there were no catastrophic injuries, such as ACL or Achilles injuries. This was not a scientific study (and the data could be dismissed as N=1), but again, success leaves clues! Oh, I should also mention that within a year, the class had 12 girls clean 135 pounds and nine girls vertical jump over 23 inches.

Besides weightlifting and unique jump exercises, iso-inertial training using flywheel devices is another way to injury-proof the body. Share on X

Now let’s see what modern technology has to offer. Besides weightlifting and unique jump exercises, iso-inertial training using flywheel devices is another way to injury-proof the body.

Gagné has used iso-inertial training with pro hockey players and elite athletes in other sports for more than a dozen years. Among his success stories are the three Dufour-Lapointe sisters who compete in mogul skiing. In 2014, Justine won Olympic gold, Chloe won silver, and Maxime joined them as an Olympian. Gagné has been their only strength coach and has used iso-inertial training with these remarkable athletes since he started with them.

Olympic Sisters
Image 8. The Dufour-Lapointe sisters competed in the 2014 Olympics, capturing gold and silver for Canada. Paul Gagné, shown at right, has been their only strength coach.

Gagné says iso-inertial devices enable athletes to perform numerous resistance exercises at high speeds during the concentric (muscle shortening) and eccentric (muscle lengthening) phases. “The goal is not only to increase force production but to enable the muscles to contract and decelerate faster,” says Gagné. “Being able to decelerate faster enables the athlete to change direction faster.” Consider sprinting.

One component of running speed is ground contact time—the less time athletes spend on the ground, the faster they go. Iso-inertial training enables athletes to flex and extend their legs and ankles faster, reducing ground contact time so that the athlete covers more ground with each step.

“This is why iso-inertial training is so good,” says Gagné. “The flywheel forces you to transition quickly between concentric and eccentric muscular contractions, which is the key in any sport. It’s not at the top of a movement when you want to produce the most force; deceleration occurs in sports at the top of the movement, where injury happens. At the bottom of a movement, a stretch reflex will help get you out.” Gagné added that iso-inertial training complements weightlifting, and he used it when he trained Luna-Grenier.

Iso-Inertial

As a bonus, because iso-inertial training focuses on the dynamic properties of the connective tissues, it will result in little or no soreness. “Slow, eccentric training is most responsible for muscle soreness,” says Gagné. “If you were to slowly walk down several long, high hills the next day, you might experience a high level of soreness. Iso-inertial training involves fast eccentric movements, utilizing the elastic components of the tissues, so post-workout soreness is rare. Likewise with weightlifters—rarely have I ever heard of weightlifters complaining of muscle soreness.”

Because iso-inertial training focuses on the dynamic properties of the connective tissues, it will result in little or no soreness. The lack of muscle soreness has significance for program design. Share on X

The lack of muscle soreness has significance for program design, particularly in-season training. How often have sports coaches, particularly sprint and jump coaches, forgone any resistance training in-season because they feared their athletes getting sore? The result is that athletes make minimal gains in strength during the year, as much of their training is regaining the strength they lost from these in-season “maintenance” phases. Thus, the strength coach is happy to train athletes harder in the weight room, and the sports coach is happy because their athletes are not sore going into practices or competitions. It’s a win-win!

To summarize, here are six key points I want you to take away from this article:

  1. The continued high rates of non-contact ACL and Achilles injuries suggest that many training methods to prevent these injuries are ineffective.

  1. The risk of ACL injuries in women due to structural and hormonal differences may be exaggerated.

  1. Athletic tape and bracing have their place in sports performance. However, if used as a preventive method in non-injured athletes, they may increase the risk of ACL and Achilles injuries.

  1. The ability to relax muscles quickly is a critical component of athletic performance and injury prevention.

  1. Weightlifting and fast eccentric exercises may reduce ACL and Achilles injuries by enabling athletes to better deal with excessive stress and unstable conditions.

  1. Fast eccentric training enables athletes to increase power production without experiencing high levels of muscle soreness.

Can the ideas I shared with you guarantee that an athlete will never tear an ACL or Achilles tendon? Of course not. However, when you train the body how it was meant to move and perform, there is a good chance that “non-contact injury” may no longer be part of your vocabulary!

BJJ Training

Developing Strength, Power, and Endurance in the Brazilian Jiu Jitsu Athlete

Blog| ByJimmy Pritchard

BJJ Training

Brazilian jiu jitsu (BJJ) is a grappling sport that was derived from Judo in the early 20th century. Long-time Judo practitioner Mitisuyo Maeda spent significant time traveling around the globe spreading knowledge and teaching Judo techniques to students in various countries. Eventually, he crossed paths with Brazilian natives Carlos and Helio Gracie, who took the techniques they learned from Maeda and adapted them to fit their physical capabilities more appropriately, which did not include size or strength.1 This is widely considered the birth of BJJ, which allows the smaller or less physically gifted individual to defeat a larger opponent through technique.

Since its inception, BJJ has grown in popularity, primarily due to its successful use in mixed martial arts (MMA) fights and self-defense situations.2,3 As BJJ has grown in popularity, so too has the research behind the physiological makeup of the BJJ athlete and effective training methods to develop strength, power, and endurance for grappling. Sound technical and tactical strategies will always remain the backbone of success in jiu jitsu; however, developing strength, power, and endurance are now a critical piece of the puzzle for hobbyists and elite practitioners who wish to maximize their potential. In order to improve said physiological qualities, one must first understand the demands of BJJ on the athlete and the appropriate training strategies to improve performance potential.

As Brazilian jiu jitsu has grown in popularity, so too has the research behind the physiological makeup of the BJJ athlete, says @jimmypritchard_. Share on X

The Breakdown of BJJ

As previously mentioned, BJJ plays a major role in the overall arsenal of many MMA fighters, but it is a competitive sport in its own right, too. BJJ matches are classified as “Gi” or “No-gi,” where the athletes are either wearing a thick kimono (known as a gi) or tight compression apparel, respectively. Both styles of BJJ have their own technical nuances, but the overarching goal of both styles remains the same.

Every match begins with both athletes standing and attempting to either take their opponent down or pull-guard (attacking from the bottom position). The objective is to win by securing a chokehold or joint lock, which ultimately forces the opponent to submit or “tap” to avoid being strangled unconscious or suffering injury from joint manipulation. If neither grappler can submit the other, the grappler who accumulated the most points for dominant positions is awarded the win for the match.

Match length varies depending on one’s skill level and rank with the following times being most common:

  • White belt: 5 minutes
  • Blue belt: 6 minutes
  • Purple belt 7 minutes
  • Brown belt: 8 minutes
  • Black belt: 10 minutes

Elite or professional jiu jitsu athletes may have only one match against a predetermined opponent as in MMA; however, the overwhelming majority of BJJ matches occur in tournament-style brackets, where an athlete may have 4-5+ matches in one day. This style of competition and the training itself place a huge demand on the athletes, requiring them to prepare with sound strength and conditioning methods for optimal performance outcomes.

Strength

While BJJ relies heavily on technical ability to defeat an opponent, strength underpins the ability of the athlete to express said abilities against another skilled opponent, making it an important attribution to the overall makeup of a BJJ athlete.4 Research by Andreato et al.5 has demonstrated that BJJ athletes possess excellent abdominal/upper body strength and endurance, as well as high levels of isometric low back strength. More specifically, grip strength, pulling motions (dynamic strength), resisting positional advances against an opponent (static strength), and holding an advantageous position all require high levels of strength from the BJJ athlete.1

BJJ athletes possess excellent abdominal/upper body strength and endurance, as well as high levels of isometric low back strength, says @jimmypritchard_. Share on X

The degree to which strength ultimately determines success in a BJJ match is difficult to quantify due to the collective variables at play, including technique, experience, weight division, and fatigue. Regardless, with the findings from this research along with a biomechanical analysis of the sport, it could be argued that developing an adequate level of maximal strength and subsequent strength endurance, particularly through the upper body/trunk area, aids BJJ performance positively.5

Power

BJJ requires slow/static movements to control one’s opponent and apply force during submissions; however, several instances occur where these movements need to be executed in a rapid fashion. A match can end in a matter of seconds or grind for 10+ minutes (black belts). Research demonstrates that during the average competitive BJJ bout, each 117-second block of work contains four 3-5 second expressions of high intensity effort followed by 25 seconds of lower intensity work, bringing the “Hi:Low” work to rest ratio (HI:LO) to around 1:5.6,7,8 This indicates that the adenosine triphosphate phosphocreatine system (ATP-PC) is in fact an important part of the BJJ athlete’s performance make-up, as it is the primary fuel source for these high force expressions.8

The high force expressions include things such as takedowns, throws, positional/submission escapes, and certain submission applications. A high level of technical mastery is required to apply high force with a technique at a particular time to induce a successful outcome. It is particularly advantageous for a BJJ athlete to possess adequate rate of force development (RFD) ability relative to their body weight, as they compete against athletes that are the same size as they are more often than not.9

Endurance

A BJJ athlete requires both anaerobic endurance and aerobic capacity to be well suited for competition.10,11 The ability to withstand the acidosis produced from buffering hydrogen ions during a bout is key for the athlete’s ability to maintain grip controls, frame against their opponent, apply submission techniques, escape, and perform nearly all other continuous activities involved in the sport.5 However, when it comes to training, direct comparisons between methods of preparation for BJJ and other grappling sports (such as wrestling and Judo) have led to confusion.

A BJJ athlete requires both anaerobic endurance and aerobic capacity to be well suited for competition, says @jimmypritchard_. Share on X

Judo, for example, typically only contains 30-37 seconds of work followed by 10-15 seconds of rest, or a 3:1 work to rest (W:R) ratio, whereas BJJ contains around 117 seconds of work with a 20-second pause, or 6:1 W:R ratio.10,12 This paucity creates confusion amongst researchers and practitioners who may equate the conditioning needs of a BJJ athlete to that of other grappling sports when in fact it is quite different.10

Aerobic capacity contributes to the recoverability both within and between matches for the BJJ athlete. As matches get longer and closer to the 10+ minute mark seen at the black belt level, aerobic capacity becomes even more pertinent.1,8,11

Injuries and Mobility

One of the known dangers of competing and training in a grappling sport is the inherent risk of injury. BJJ athletes are attempting to manipulate one another’s joints to the point of damage prior to forced submission, which, when combined with chaotic scrambles for dominant positions or unpredictable counter movements from the opponent, can lead to an array of both acute and chronic injury accumulation over time. This is due to the compression, torque, and wear/tear on the body that occurs in training and/or competition. One research study by Scoggin et al. examined the prevalence of injury occurrence during BJJ competition and found an injury rate of 9.2 per 1000 exposures, 78% of which were orthopedic.13 The elbow joint was most injured due to the “arm bar” joint lock submission, occurring twice as often as knee injuries and three times as often as ankle/foot, hand, and shoulder injuries collectively.

Considering whether these types of injuries are preventable or not is an interesting concept. Competition is particularly chaotic and unpredictable, meaning that anything can happen. Interestingly, a vast majority of injures appear to occur during training, which is far more controllable, suggesting that coaches and athletes could more closely monitor training scenarios so that risk for injury is reduced.14 In addition, BJJ athletes can certainly make themselves more robust and resistant to injury by obtaining adequate mobility through the shoulders, hips, lumbar spine, and posterior chain so that they are more easily able to maintain position, recover guard, execute sweeps, and escape unfavorable positions.15

A major opportunity for further research would be to analyze common BJJ injury data and compare the training regimen, nutrition, medical history, recovery tactics, and lifestyle of the given athletes to better understand potential mechanisms of injury. Due to the nature of BJJ, injuries are always a possibility, meaning that athletes and coaches should aim to strengthen all areas of the body including the neck, shoulders, hips, knees, elbows, back, and ankle/foot to reduce the likelihood of injury occurring.

Training

Devising a training plan that meets the demands of a BJJ athlete is a delicate blend of volume, intensity, frequency, and exercise selection. Performance training that detracts from or negatively impacts BJJ-specific training should be avoided. This becomes difficult from a recovery standpoint when a BJJ athlete trains 5-6 times a week for 1.5-2 hours at a time and perhaps competes dozens of times per year.

Outside of enhancing performance, several key considerations for a BJJ training program include the following:

  • Most BJJ athletes compete in a specific weight class—therefore, excessive muscular hypertrophy should be avoided in most cases, unless the athlete wishes to compete at a higher weight class.
  • High volume, high intensity BJJ skill sessions can put major stress on the joints and compression/torque on the neck/mid-low back. Consequently, exercises must be selected carefully so as not to further stress these areas.
  • Scheduling workouts throughout the week must be done carefully to allow for enough recovery between sessions.
  • Less can often be more. The overarching goal of strength and conditioning for BJJ is to provide the minimum effective dose for the desired adaptations and ultimately allow for more time to train BJJ, recover, or possibly cut weight if necessary.

Practical Application

There is no “one size fits all” programming style for the BJJ athlete due to factors such as skill level (elite vs. non-elite), age, training availability, experience, and injury history. While no two BJJ athletes’ schedules are alike, most serious competitors have their competition schedule laid out far in advance to allow for proper training camps and potential weight cutting. The examples provided below demonstrate snapshots of an eight-week periodized training cycle, which begins with strength endurance and ends with a focus on maximal strength and power.

There is no “one size fits all” programming style for the BJJ athlete, says @jimmypritchard_. Share on X

This would be ideal if a BJJ athlete has a break in their competition schedule or very few competitions of importance during the training period. The traditional “annual plan” where an athlete goes through extended offseason, preseason, and in season training periods does not apply to the BJJ athlete due to the fact that competitions can occur year-round and there are almost never extended periods of time where one stops training. Below is a further look at the first block of training focusing on strength endurance.

Endurance Week
Table 1. Example of programming week focused on improving strength endurance.
*(5:2) indicates cluster set: complete 5 reps, rest 10 seconds, and repeat until all fifteen are done.

This block is intended to build the athlete’s ability to withstand stress and workload accumulation for higher intensity training to come in later weeks. Several methods accomplish this, including cluster sets, which are a popular resistance training strategy using short periods of rest between single or groups of repetitions within a set.16 Cluster sets are used for key primary exercises such as the Zercher squat and trap bar deadlift to allow for both improved technical execution and the potential for greater load. Various exercises targeting the low back/posterior chain (reverse hyperextensions, split stance RDLs, etc.) and upper body (single-arm KB press, half kneeling landmine press, gi chin-ups, etc.) are used to address the specific needs of BJJ athletes as discussed earlier. Each session is considered a “full body session” so that volume is dispersed throughout the week, which helps reduce the likelihood of soreness and fatigue accumulation compared to an upper or lower body split routine.

On Tuesdays and Saturdays, the conditioning is general and aimed at improving the athlete’s aerobic power through maximum aerobic speed training (MAS).9,17 In this example, running is used as the primary method on Tuesdays and rowing on Saturdays. While this W:R ratio is simply 1:1, it can be later adapted to meet the demands of BJJ more closely as discussed previously in the endurance section.

The next block highlighted below is from week 6 (of 8) in the program, where the primary emphasis has shifted towards developing strength and power.

Strength Power Week
Table 2. Example week of programming focused on improving strength and power.
*Mas = Maximum Aerobic Speed
*KB = Kettlebell, *DB = Dumbbell

In this block, the athlete’s volume has dropped significantly; however the intensity has also increased significantly. Exercises such as the barbell back squat and rack pull are used to initiate high force production from the athlete and are paired with contrasting high velocity movements such as box jumps and power cleans. Key areas of the body (e.g., low back, posterior chain, back, shoulders, etc.) are all still addressed as well; volume for these movements, however, is at a maintenance level in order to not overload the athlete and create undue fatigue.

The conditioning in this portion of the program is targeted at short bouts of high intensity exertions paired with intermediate bouts of moderate intensity exertion, as seen by the MAS workout on Tuesday. Saturday’s MAS workout is optional and can be replaced with a low intensity steady state session if BJJ sport training is becoming more pertinent and higher intensity.

Balance

Balancing a weekly schedule in BJJ training is a difficult task, as previously mentioned. A fine line exists between overtraining and under-recovering—therefore, practitioners and coaches alike must be meticulous with the way they devise their weekly training routine. The previous two training examples gave insight into how one may train specifically in the gym to improve their BJJ performance, but the example below provides insight into how one may balance physical technical/tactical training throughout the week.

BJJ Week
Table 3. Balancing performance and sport-specific training during the week for BJJ.

Competitive BJJ athletes will likely do some form of technical/tactical training on a daily basis, therefore the key is to set up training such that it never detracts from that. Good strategies as depicted above are:

  • Dividing physical and technical/tactical training into AM/PM sessions (ideally 4-6+ hours apart):
    • Strength training in the AM if BJJ is to be done in the PM so that performance is not compromised in the gym.
    • Conditioning in the PM if BJJ is to be done in the AM so that performance is not compromised in BJJ training.
  • Allowing a minimum of one full day rest per week.
  • Oscillating between higher and lower intensity/volume days throughout the week.
  • Keeping volume during strength training to a “minimum effective dose.”

Final Takeaways

BJJ is a rapidly evolving sport that requires an array of physical and technical competencies to be successful. A delicate balance exists between performance training for BJJ and actual BJJ training in that the former must be careful not to detract from the latter, but instead serve as an enhancement. Keeping the BJJ athlete healthy and ready to compete are two of the most important aspects of a BJJ training program, followed by:

  • Specific endurance.
  • Strength.
  • Power development.

Research analyzing the specific physiological profile of elite BJJ athletes and mechanisms of injury is continuously evolving with several informative pieces of literature being published in the past 5 years alone.4,5,9,12,18 In addition to this literature, a major opportunity exists for further research to take place in analyzing the aforementioned areas of performance and physiology in BJJ.

Recognizing and Developing Talent on the Track with Karl Goodman

Freelap Friday Five| ByKarl Goodman, ByDavid Maris

Melissa Jefferson

Karl Goodman is the Associate Head Coach at Coastal Carolina. He is the coach to two World Relay Champions (Senior & Under 20), two USA Champions (Senior and Under 20), one NCAA Champion, 12 All-Americans, 20 Conference Champions, and 31 Conference medalists, and he has also coached athletes to seven Sunbelt records. Karl holds an MSc in Exercise Physiology from the University of Texas at Arlington, and he was a collegiate athlete representing UTA and the University of Mount Olive.

Freelap USA: You’re a young coach in the collegiate system and have some great mentors. Can you share some of the coaches that have had a big influence on you and what you have taken from them?

Karl Goodman: The biggest influence on my practice is the staff at UT-Arlington, and Coach Tyrone Edgar in particular (who is now at TCU). I was a graduate assistant at UTA, and Edgar taught me how to recruit and identify talent and wasn’t afraid to tell me if I was doing something wrong. If I set up a practice wrong, he would explain the mistakes and make me do it again. I really appreciated the fact that he was so honest with me because it enabled me to see some of the shortfalls I had in my own practice and work on them to become a better coach.

Goodman Edgar
Image 1. Coach Karl Goodman with Melissa Jefferson (left) and Coach Tyrone Edgar (right).

Coach Edgar also had a lot of good mentors, so I could ask him about his experiences with John Smith, Pat Henry, or Dan Pfaff, for example. He and I still bounce ideas and workouts off each other. In the past, we were in the same conference—so while it could be seen as competitors helping each other, we just tried to elevate and bring the best out of each other. I see him as a big part of why I’ve been able to help the athletes I’ve had be successful, and I’m thankful for that.

Additionally, Coach Matt Kane has been very helpful, and we’ve spoken a lot about the transition from being a collegiate athlete to being a professional athlete. Prior to his current role at FSU, he exclusively coached professionals. He still has some pros alongside his college group, such as Trey Cunningham, who went professional at the same time as Melissa Jefferson. He’s helped me with workouts and interpreting workout performance and determining what that may translate into in racing performance, specifically with regard to the 100m.

Melissa Karl Sandy
Image 2. Coach Karl Goodman with Melissa Jefferson and Sandy Fowler.

Coach Sandy Fowler, the Director of Track and Field at Coastal Carolina, has been great for my development. She has given me a good deal of autonomy within my role and allows me to spend the bulk of my time actually coaching on the track, working with the 32 sprinters and hurdlers we have on our roster. The way she has managed and delegated tasks has really allowed me to refine and develop my coaching practice.

I have also had Zoom conversations with Håkan Andersson regarding resisted sprinting and how to implement that into my program. I have to say he has been really helpful in this regard.

Freelap USA: You grew up in the south of England before competing as a collegiate athlete and then coaching in the U.S. What are some of the differences you’ve noticed between being a young athlete in the UK and a young athlete in the U.S.? Do you think your coaching experience would be different if you were in the UK?

Karl Goodman: I wasn’t ever an international-level athlete, but my experience of being an athlete in the UK is that it was more of an amateur setup and largely required self-motivation. I didn’t have to train if I didn’t want to, for example, and my dad would drive me to training twice a week to be coached by volunteers—whom I had a tremendous amount of respect for because they did this on their own time out of love for the sport.

At the top junior level, my perception is the British athletes might have it easier because there isn’t the same depth as in the U.S. Therefore, they may get made to feel more special and get access to resources, such as treatment, that they might not be entitled to in the U.S. if they were running the same times. And I wonder if this impacts how effective Great Britain is at transitioning junior talent to senior talent. Admittedly, I don’t know a lot of these athletes’ backgrounds and circumstances. Still, from an outsider’s perspective, I feel like I see a lot of talent at the junior level in the UK that I would expect to see do well as a senior, yet it often doesn’t happen.

In the U.S., I think you have a spectrum where, at one end, you have a high school athlete who has a private coach, facilitated by the financial investment of their parents in the hope of them getting an athletic scholarship—and this can be the case even if the athlete may not love the sport. On the other end of the spectrum, you have under-coached athletes who simply do the high school season without any external coaching. They may have more of a love for the sport as they haven’t been exposed to so much pressure, and their involvement is perhaps for purer reasons.

In terms of coaching in the UK, I think many of the more prominent coaches have either been international athletes themselves or have, at some point, been through a UK Athletics apprenticeship-type program. As I do not fall into either of these categories, I am not sure if I would have the same support or opportunities to be successful there that I do here.

The U.S. collegiate system is a very chaotic environment, with many other factors outside of writing and managing a training program built into the role, says @karlgoodman. Share on X

The U.S. collegiate system is a very chaotic environment, with many other factors outside of writing and managing a training program built into the role. I think this can bring challenges to the role that a developing coach in the UK may not be prepared for. Of course, there are different challenges in the UK, so while it is a chaotic environment in the U.S., there are structures and systems in place to hold the athletes accountable and make sure they are at practice. In the UK club coaching sector, it is far more challenging to provide the athletes with the same level of accountability.

Freelap USA: You have done a fantastic job with Melissa Jefferson, and it was really only in 2022 that the track community realized how talented she is and how much potential she has. Were you expecting her to be as good as she is when you started coaching her? Was there anything you saw in her that you feel others may not have seen?

Karl Goodman: I started my coaching position at Coastal Carolina when Melissa started her first year, so I wasn’t involved in recruiting her. However, when I took the position, looked through our roster, and checked everyone’s performances and videos on MileSplit, I saw the state championship in which Melissa was racing, and her frequency stood out. To this day, that is still one of my favorite races to watch, and despite her time only being 12.0, it appeared to me that she had something special.

Throughout her first season, which was the first year impacted by the pandemic, I noticed she was making sacrifices that a first-year college athlete typically would not. For example, she paid special attention to things like her diet, and she would come to the office early in the morning and ask me if we could do some extra practice before the actual session was scheduled to start. Additionally, while she did not have a 400m background, due to the fact we didn’t have a huge amount of depth at this time, she would run a leg of the 4×400 meter relay with no questions asked.

All this demonstrated how motivated she was, and combined with her talent, I believed she was going to do something special. I remember being in a staff meeting in February 2021 and telling the coaching staff that I thought Melissa would run 10.9. From then on, I set about fixing some of the issues that I felt prevented her from expressing that level of talent, most of which were centered around her acceleration. If you look at her 60 meters progression, you can see that in 2020 she ran 7.55; in 2021, she ran 7.41; and in 2022, she ran 7.09.

Throughout the first year, we worked on her maximum velocity a lot—through wicket drills, for example—and while that improved, it wasn’t translating as well as I would have liked to better race performances. What I found was that Melissa could execute maximum velocity mechanics really well from a standing start, but it was more of a struggle for her to do so from blocks. We went about targeting her acceleration so that she could use it to set up her positions better to capitalize on the maximum velocity skill set she had already developed early in her collegiate career. It didn’t need too much tweaking apart from perhaps trying to increase her stride length slightly.

Freelap USA: What are your key performance indicators for sprint performance? Do you use much technology to help you assess whether an athlete is improving with training?

Karl Goodman: With Melissa, the two main tests I use are a 300-meter time trial in the fall to assess her specific endurance qualities and a 40-meter test to assess her acceleration. Many of my assessments have been based on what I see and hear: Is the athlete hitting the positions I want? Do the ground contacts sound sharp? But more recently, I have started being more thorough with respect to timing workouts and paying attention to the progressions I see here.

For example, on our first day of practice, I had the Freelap timing system out and timed some accelerations. Then, three weeks later, I got the Freelap out again and compared the sets of times to judge if the training was trending in a positive direction, which can reinforce what I’m seeing and hearing in terms of technical abilities. As a matter of interest, before the 2022 indoor season started, Melissa had run a 7.15 60m using the thumb pad, so I had a strong inclination that she was ready to run fast that season.

I’m not sure if it necessarily counts as technology, but I mentioned I use resisted sprints, and I am starting to implement more assisted sprinting into the workouts. However, I want to be very careful how I do that to ensure I’m not doing any damage. Therefore, I have slowly added this into the program in small doses and seen how the athletes respond, and then I adjust the dosage from there.

A benefit I see with technology is that it holds the coach accountable, says @karlgoodman. Share on X

One point I would like to stress is that a benefit I see with technology is that it holds the coach accountable. The implementation of technology often requires planning and/or setting up. Therefore, if I want to use technology, it means I need to invest time in planning and setting up the sessions properly before the athletes are out on the track.

Freelap USA: What does a typical training week look like for Melissa?

Karl Goodman:

    Monday – Extensive/intensive tempo day that is typically 800–2000m volume, often with circuit exercises between the runs to assist in conditioning the athlete while avoiding extra impact that greater running volume would incur. Lift.

    Tuesday – Acceleration and shorter speed work. We typically do acceleration work and finish with a rep or two in the 50–60 meter range, but we never go further than 60 meters here. Lift.

    Wednesday – Recovery day, which might be yoga, massage, bike, or pool; in the off-season, this is largely up to Melissa. But as we get toward the season, I’ll guide her more toward yoga or massage than bike or pool.

    Thursday – Maximum velocity and shorter speed endurance with work in the 12–18-second or 120–150-meter range. I may include some wicket drills or runs over 50, 60, or 80 meters in the maximum velocity component, and Melissa particularly likes workouts such as 60m, 90m, 120m, 150m, 120m, 90m, 60m or 30m, 60m, 90m, 120m. Lift.

    Friday – Hills, and this can be a combination of short and long reps to develop acceleration and/or conditioning qualities, depending on the time of year and the goal of the workout.

    Saturday – Exercises that take place on the track or turf (but typically not running) geared to power development, such as bounding.


This is the basic structure, but I am flexible with this. Things like the weather can place constraints on what we do, so I may move the days around. In the same respect, sometimes, if it’s colder and I don’t feel that it’s safe for the athletes to be running on the flat, I may swap in hills for any of the track sessions as well.

In addition to this, Melissa will lift on Monday, Tuesday, and Thursday, and we have been experimenting with a fourth day of lifting because I felt she needed to add a little bit more mass as she was very light by the end of the season.

Improving Your Recovery with NormaTec Go

Blog| ByDanny Foley

Normatec Go

With the recovery and restoration market exploding over the last decade, it has become somewhat difficult to differentiate quality products that offer valid solutions from gimmicks. The essence of recovery is to minimize the margins of deficits by keeping athletes as close to their physiological equilibrium as possible—as we know, this starts by managing training inputs (volume, intensity, workload) appropriately and establishing the fundamentals (sleep, nutrition, stress management).

Once those items are addressed, it then becomes a continuum of balancing acts between monitoring load , applying stress, and implementing recovery strategies for your athletes. While the fundamentals apply equally across all individuals, recovery in itself can be highly individualistic, where more nuanced and specific restoration modalities may be needed or desired.

Recovery Pillars
Restoration is a multivariant process, as it requires attending to multiple subsystems and is a different process for every athlete. But a major component of this equation is managing blood flow: namely, promoting venous return. Although there are several ways we can directly improve blood flow, NormaTec compression boots have been a staple in the Rude Rock recovery paradigm for years. NormaTec uses external pneumatic air compression (EPC) to help promote increased venous return, particularly following bouts of exercise.1 The mechanism is simple and largely effective, utilizing an alternating cadence of compress-relax; the NormaTec boots help blood flow back to the heart through this pumping action.

Aerobic Capacity
While the NormaTec boots have been a popular tool for several years, NormaTec has more recently launched the NormaTec Go. This is an innovative version of their conventional boots that offers the same premise but is much more versatile and convenient for use. This streamlined version of NormaTec has been a tremendous addition to our recovery protocol and, as far as we’ve been able to tell, provides the same impact on enhancing circulation.

The NormaTec Go offers the same premise as the conventional boots but is much more versatile and convenient for use, says @danmode_vhp. Share on X

With the demands of sport and life continuing to increase for us all, practicality and feasibility of implementation are necessary considerations for coaches and practitioners. Although we can often become dismayed or frustrated by the lack of physical time we have with our athletes, it has since become our responsibility to be more versatile with our approach and strategies. A part of this strategizing requires us to consider ways we can buy time for ourselves in training but also keep the extraneous tasks at a minimum for our athletes. It’s in situations such as these that the NormaTec Go unit has really demonstrated its value—with a minimal setup requirement, no time impediment, and the ability to perform daily/life tasks while you recover, the NormaTec Go really offers the user a more-bang-for-your-buck recovery option.

Benefits of Improving Circulation

Irrespective of the individual deficits or demands of sport, improved circulation is invariably important for optimizing health and performance. As athletes continue to be exposed to high stress demands and accumulate injuries or wear and tear, optimal circulation can become evasive.

Beyond diagnosed metabolic or cardiac ailments, overtraining, musculoskeletal injuries, and even head injuries can also lead to compromised blood flow, as body-wide fluid dynamics may be disrupted or altered.2 Improving blood flow should also be a consideration for athletes who’ve suffered severe lower-extremity injuries, such as ACL or Achilles tears, or more chronic issues such as plantar fasciitis or shin splits. The resulting inflammation from lower-extremity injuries can have adverse effects on venous return as the injury heals.

Accumulatively, changes in blood flow or return can have adverse effects on health and wellness: namely, deprived oxygen to muscles, disruption to HRV, or onset of chronic fatigue/illness.

It has been well documented that foot and lower leg circulation are generally more easily compromised than other areas of the body. Although this is thought to be an effect of gravity, it is primarily due to the weight of the blood in the venous structures of the leg column making it more difficult for it to travel back to the heart. Compromised venous return has been shown to have a direct link to adversely influencing overall stroke volume and cardiac output.3 As individuals age, become deconditioned, or experience bouts of high stress demands, venous return can become further compromised.

This is where the application of NormaTec is really useful, as the compression mechanism of the NormaTec Go assists in this pumping action. As a result, deoxygenated blood is accelerated back to the heart to be reoxygenated. Depending on the athlete or individual, the effects of lower leg compression may be limited to just transient local improvements, while for others, it may have more of a global effect. This typically corresponds with the general state of the individual’s cardiac and metabolic health.

Blood isn’t the only fluid that benefits; other vital biological fluids like lymph, interstitial fluid, and hyaluronic acid are also accelerated during modalities like NormaTec sessions. Share on X

I should also note that when we discuss improving flow, blood isn’t the only fluid that benefits. Other vital biological fluids like lymph, interstitial fluid, and hyaluronic acid are also accelerated during modalities like NormaTec sessions. The lymphatic system is critical for processing metabolic waste from the bloodstream and is fundamentally an essential contributor to not only acute recovery but overall health and wellness as well. Unlike the cardiovascular system, which has an internal mechanical pumping action to help drive flow, the lymphatic system does not have the same type of pumping action to facilitate movement. As such, things like the NormaTec Go sleeves are likely highly beneficial for helping the flow of lymph by providing a compression-relaxation mechanism to the calves.

For athletic populations, accelerated venous return may not be an outcome-determining factor, but it can certainly play a small role in the recovery process. For more of the general population, particularly aging adults, something as simple as improved venous return may be more decisive in promoting accelerated recovery and allow them to train at a higher intensity, frequency, or both.

If we go a step further and consider individuals with poor metabolic or cardiovascular health—for instance, low-level ankle edema, high blood pressure, or pre-diabetic—then products like the NormaTec Go may be even more valuable. Providing assistance for blood flow for these individuals becomes even more significant and may be a fundamental component of their maintenance strategies. And for all groups listed, I would venture to say that improving lymphatic flow will be a significant factor for just about any individual or athlete.

The Convenience of NormaTec Go

I believe the ultimate value of the NormaTec Go unit is in its versatility and ease of use. As discussed in the opening paragraphs, time is fleeting for us all, and as life continues to throw impediments at us, managing and sustaining things like recovery protocols can fall by the wayside.

While it may seem like a bit of an inflated point, I believe we need to be considerate of the efficiency with which we task our athletes, and the NormaTec Go certainly checks this box. The NormaTec Go unit runs on a cordless battery, allowing you to be mobile during use, which provides a huge incentive to remain consistent with your routine. Moreover, the battery life is impressive, as a full charge gives you about 10 hours of usage time before needing another charge.

The NormaTec Go is a very efficient product with the potential for great impacts on certain populations while likely being at least somewhat beneficial for just about anybody, says @danmode_vhp. Share on X

The product is also lightweight, durable, and small enough to fit into a backpack or carry-on bag with ease. An effective treatment session does not require much, as it appears to be sufficient to use it for 15–20 minutes for 4–5 days per week. All in all, this is a very efficient product that has the potential for great impacts on certain populations while likely being at least somewhat beneficial for just about anybody.

Power

Developing Elite Football Talent with “Power”

Blog| ByJoshua Martin

Power

Performance attributes are measured in many ways. In every industry, key performance indicators (KPIs) are all the buzz.

In strength and conditioning (S&C), we commonly use KPIs from sprint times, shuttles, jumps, benches, squats, deadlifts, and other exercises. Are we missing the point of using highly skilled exercises to predict athlete performance?

Utilizing physics and Newton’s 2nd Law may be the simplest way to evaluate an athlete. According to Joel Jamieson, sports can be broken down into three main components:

  • Performance
  • Skill
  • Tactical

Coaches need to start bridging the gap between performance and skill training components. S&C coaches spend most of their time facilitating performance components, while sports coaches primarily focus on skill and tactical components. For sports coaches, this includes the scheme and strategies they plan to use in competition.

In football, these elements are used to create an advantage or negate one, taking numbers, vectors, and relative space into consideration. An easy way to think about the modern game of football is that the offense’s goal is to create space, while the defense’s goal is to take away space. S&C coaches are tasked with increasing their athlete’s performance-related attributes, such as power.

An easy way to think about the modern game of football is that the offense’s goal is to create space, while the defense’s goal is to take away space, says @CoachBubsMartin. Share on X

In football, power wins—it is so highly regarded that at the core of the game is the run concept called “Power.” For that reason, I will break down key blocking responsibilities in that Power play later in the article. I will provide specific movement techniques and vectors as examples of how the three components of sports connect in training.

In physics, power (P) is the product of force and velocity or mass, acceleration, and velocity. Ultimately, we work to produce large amounts of force at a rapid rate and in the most efficient angle possible. At MVP Academy, we use the following terms:

  1. Force Production—High ground contact times
  2. Rate of Force Production—Low ground contact times
  3. Force Application Angles—Vectors

Force Production

Newton’s 2nd Law tells us that Force = Mass x Acceleration. In the weight room, we increase force production over time through one of two methods: increasing load (increase in mass) or increasing how fast we move a given load (increase in acceleration). This can be perceived as the “S” portion of the “S&C” in our field.

An absurd number of methodologies have proven to increase strength. I’d say that most S&C coaches are effective with this prescription. We will leave the “my kung fu is better than your kung fu” discussions for the bird app.

On the field, high-force production events are seen in high accelerations, decelerations, and impacts. These movements require longer contact times to produce these higher outputs of force. When training on the field, we simply “slow the athlete down” by adding some form of resistance or opposing motion. This may be in the form of sled towing, pushes, hills, bands, or various other methods. Intensive plyometrics, jumping for maximum height or distance, and resisted or loaded jumps are other prescription methods that help increase force production.

Rate of Force Production

To increase the rate at which force is produced, we aim to “speed the athlete up.” In the weight room, we can move a very light load faster—increasing the number of reps in a short, specific amount of time—or prescribe assisted movements with bands, etc. We want to prescribe movements requiring shorter ground contact times and minimize the time in which we produce a given force.

How hard we push is not the goal. We want to get the load away from our torso or get off the ground as fast as possible: the floor is lava. Extensive plyometrics and assisted jumps with bands are methods we can use to increase the rate at which athletes produce force.

On the field, there is no better way to train an athlete to increase their force production and stride frequency rate than maximum velocity training. The fastest a human can move their body is by sprinting and achieving maximum velocity. The best method to do that is with flying sprints.

We tell our athletes constantly, “Want to get fast? Run FAST! Want to stay fast? Run fast consistently!” Once our athletes have progressed to maximum velocity drills, we do at least three reps of flying 10s a week, with either a 20-yard or 30-yard build-up. We prefer to use a 30-yard build-up in our athletes because they just don’t yet have the acceleration capabilities to hit maximal speeds in 20 yards. These end up being full sprints for 30 yards, which defeats our intent of limiting load by doing minimal reps of flying 10s.

Force Application Angles

The closest distance between two points is a straight line. When athletes learn how to create good angles, they can efficiently use the forces they produce. An easy way to teach this is with vectors. At the NHSSCA National Conference in Nashville, Tennessee, Bobby Stroupe described how he teaches his vector system.

When athletes learn how to create good angles, they can efficiently use the forces they produce, says @CoachBubsMartin. Share on X

There are eight basic vectors. We can use the navigational directions as a guide; imagine facing north, going clockwise.

  • North = 0°
  • Northeast = 45° (right)
  • East = 90° (right)
  • Southeast = 135° (right)
  • South = 180°
  • Southwest = 135° (left)
  • West = 90° (left)
  • Northwest = 45° (left)

Angles of Movement

Movement Patterns on the Field of Play

Sport is played at a speed set by the athletes on the field. They must play at this speed to perform skill-related tasks during play. Increasing linear speed just for the sake of running a fast 40 or any other exercise-driven event misses the point. The goal is to be good at sports.

Becoming fast enables an athlete to play at game speed at a lower relative intensity. In the game of football, the idea is to get fast so we can play slow. An athlete needs to stay under control and move efficiently to get into the positions and postures to make plays.

Becoming fast enables an athlete to play at game speed at a lower relative intensity. In the game of football, the idea is to get fast so we can play slow, says @CoachBubsMartin. Share on X

On average, football is played between 12 mph and 16 mph, as noted by Tony Villani. This is clearly a submaximal velocity. One needs to be able to get to a spot in an effective position and posture to make a play. As a longtime sports coach, I genuinely feel S&C coaches can provide immeasurable value by bridging performance and skill through coaching movement patterns.

Lee Taft defines his 7 Fundamental Movement Patterns in Athletics as:

  1. Linear acceleration
  2. Linear max velocity
  3. Lateral shuffle
  4. Lateral run/Crossover
  5. Backpedal
  6. Jumping
  7. Hip turns/Flips (transitional)

We want to utilize slower movement patterns before we get into linear acceleration and, eventually, maximum velocity. Maximum velocity, by the way, is rarely reached in sports. Removing jumps and hip turns/flips, we can rank the movement patterns from slow to fast:

  1. Lateral shuffle
  2. Backpedal
  3. Lateral run/Crossover
  4. Linear acceleration
  5. Max velocity

The faster athletes move, the harder it is to change directions and transition between movement patterns. Transitions between movement patterns and changing directions must occur when an athlete’s foot is on the ground. This foot must produce force in the opposite direction of motion to decelerate, accelerate, and/or set up changes of direction. Teaching this fundamental concept helps train the athlete on foot placement and orientation.


Video 1. Each lineman can need to apply a different movement pattern when executing a given play.

TASKR

We currently use the acronym TASKR to deliver and teach our tactical scheme to the football athletes on our team. We define TASKR as:

    T – Technique. How we perform a specific task.

    A – Alignment. Where one lines up on the field of play.

    S – Stance. Related to the positions and postures the athletes should be in when the ball is snapped.

    K – Key. This is where an athlete’s eyes are. Typically, it’s the near hip of our target/assignment. This creates a high level of eye discipline. It helps us gather data before, during, and after each play, enabling informed decision-making as the game progresses.

    R – Responsibility. This defines each individual’s task or job. Any given play’s call will dictate an athlete’s responsibility, which may revise their T-A-S-K above.

How do we connect the dots between performance, skill, and tactical strategies to help our athletes succeed on the field? Let’s break down the Power of an 11-personnel offense versus a 4–2 over front (Nickel) defense. This is an early install in nearly every modern offense’s offseason.
MVP Power

We only focus on the six blockers tasked to block the six defenders in what is called “the box.” The goal is to create space (another gap, C) between the playside defensive tackle (T on the right) and end (E on the right), so the backside (L) offensive guard can wrap to block the playside middle linebacker (S).

The ball carrier (R*) will follow this guard through that gap (C*) created. The center down/back blocks on the backside defensive tackle (N on the left), and the backside tackle performs a hinge technique to protect any penetration into the gap created by the vacating guard and then looks backside, which is detailed below. In summary, this is the tactical strategy of running the play known as Power.

Power YouTube
Image 1. A breakdown highlighting roles and responsibilities in Wisconsin’s version of “Power” available here from Dustin Michelson of ChampionshipProductions.com.

Every player involved in this play requires the skill levels to perform the Technique (T) originating from their Alignment (A) and Stance (S) while maintaining eye discipline on their Key (K) to execute their given Responsibility (R*).

Kickout Technique: H-Back

The H-back, generally called a wing in this alignment, is typically lined up somewhere behind and between the playside guard and tackle. He is tasked to “Kick” block out the playside End (E). The goal is to create as much space as possible between himself and the offensive tackle.

From his alignment, he pushes off his inside foot (left) and heads at an angle to stay inside of the E. The E is taught to squeeze the down double-team block that the tackle is performing. He must aim somewhere right of the tackle’s outside hip. With his eyes on the inside edge (hip), he must attack his opponent with leverage and high force. We utilize an angled shuffle with the near (right) foot up to strike the inside (right) half of our opponent.

Hinge Technique: Backside Tackle (Left in Diagram Above)

The backside offensive tackle is tasked with performing what is commonly called a “Hinge” technique. Pre-snap, his eyes will be on the backside middle backer (W), looking for him to blitz. Out of his staggered stance—right foot forward in this example—he will perform a quick shuffle to his right by pushing off the inside of his left foot. If the W does NOT threaten him, he will perform a hip flip at approximately 45° to his left and transition into what’s most likely a shuffle to his left to block the backside end (E on left). This E will most likely be squeezing his left hip and attacking his left/outside edge because our tackle’s movement indicates a down block initially.

Wrap Technique: Backside Guard

The backside guard is tasked with performing what’s called a “Wrap” technique to the playside middle linebacker (S). There are multiple ways to perform this technique. We utilize a lateral POP start, push-open-push, into a crossover/lateral run.

The guard is taught to push with great force off his backside foot (left), which is outside and back in his staggered stance. Then he opens his front side with his foot pointed at an angle between 45° and 90° to the playside (right). Now he crosses over with his backside foot/left in the front to perform a lateral run/crossover while keeping his eyes on his target and chest square to the line of scrimmage. His goal is to clear the double-team block performed by his teammates on the playside guard and tackle with the least amount of space possible between them and himself. Once he clears, he climbs vertically to his target, S.

Down/Back Block Technique: Center

Penetration by the interior defensive lineman will destroy any run play, especially by the backside tackle versus Power. Any penetration risks the wrapping guard being disrupted on his path, which increases the chances of freeing up the playside middle linebacker. The center’s job is to eliminate penetration by cutting the defender’s path off. He must take an angle, sometimes lateral, by pushing off his playside foot.

Some centers prefer a lateral shuffle. Positioning on the defender is more important than “blowing the guy up,” in this case. The goal is to keep the defender on the backside of the center while preventing any upfield penetration.

Apex Double-Team, Post and Gallup Technique(s): Playside Guard & Tackle

“Power is not the guard wrapping to the front-side backer. It is our ability to create movement with our front side double team to the backside backer.” – Brennen Carvalho (Center), Kaua’i native and professional football athlete

The apex double-team block on the playside of Power is the play’s most critical component. The offense’s playside guard and tackle must work in unison to move the three-technique off his spot. Ideally, they want to move him onto the lap of the backside middle linebacker.

The playside guard is commonly referred to as “the postman.” His initial assignment is similar to the center’s but on the playside. The guard must prevent any upfield penetration by the three-technique by beating him to the “spot.” The guard will push off his backside foot and attack his man by aiming to get his playside foot into the crotch of the defender.

Meanwhile, his partner, the tackle, will perform a gallop technique. Essentially, this is an angled shuffle. The tackle aims his gallop (angle shuffle) with the goal of getting the playside foot into the crotch of the defender and violently banging his hip. We want to drive through the hip of the defender to move him to the backside of the guard. The guard will take over the block by positioning himself on the playside of the three-technique, freeing up the tackle to go and block the backside middle linebacker. Ideally, the tackle wants to stay on the playside of the backside middle linebacker.

Reverse Engineering

There’s an advantage in having the ability to reverse-engineer strategies, plays, or schemes and then implement drills to build skills and the physical performance attributes needed, says @CoachBubsMartin. Share on X

The intent of this article is to share how bridging the gap between performance, skill, and tactical strategy benefits athletics. For any team, there’s an advantage in having the ability to reverse-engineer strategies, plays, or schemes and then implement drills to build skills and the physical performance attributes needed to execute these skills and strategies. This integration enhances the value of coaches and the athletes involved.

CVASPS Seminar Q&A Series: Jay DeMayo

Blog| ByJay DeMayo

Jay DeMayo

I’m really excited that Nathan and all the great people at SimpliFaster have allowed us to introduce you to our lineup of presenters for The 2023 Seminar, which will be held July 21 and July 22 at PLAE HQ in Canton, Georgia. Moving the event to a new location has allowed me to take a bit off my plate and provided an opportunity to step on stage and share some of what we do here in Richmond with our student-athletes. I’m excited to discuss the thought process and systems we have built here over the past 19 school years (you don’t get the name “Graybeard” because you stay young) and, hopefully, walk out with better ideas on how I (selfishly) can improve them.

Through this six-article series, I hope that SimpliFaster readers will come away with a better understanding of what drives the practitioners who will be speaking in July. I figured we would get me out of the way first and then bring in the real headliners who will—for sure—be the best lineup in the U.S. this year. I hope you’re able to join us, but first, enjoy our Q&A sessions.

CVASPS: What are a handful of the mistakes you routinely see made by strength and conditioning coaches in the United States and around the world, and what specifically do you feel should be done differently to correct these issues?

Jay DeMayo: In the world today, we are bombarded with information. There are hundreds of books (guilty of contributing) and podcasts (yup, guilty again) that get released yearly in our vocation. Tie in Twitter, Instagram, and Facebook (okay, I get it, I’m old—I’m still on Facebook), and you have a complete oversaturation of information in our space.

This oversaturation has led to a change in how we vet whom we learn from. At one time, it was the professors who did the research and coaches who led from the front, trying new methods with success in winning. Today, it’s who has the most followers or clout on IG, who can speak the loudest on Twitter, or who puts out the coolest infographics or videos. Don’t get me wrong, I’ve fallen into the trap here as well, and it’s led me to ask this question to each person/company I associate with/learn from: Do you do what you say you do?

Let’s say you’re selling a course or giving a talk on speed, asks @CVASPS. Wouldn’t the primary factor on whether your presentation is valid be whether you actually make people faster? Share on X

For example, let’s say you’re selling a course or giving a talk on speed…wouldn’t the primary factor on whether this presentation is valid be: if you do or do not actually make people faster? I’m all for cool-looking drills that are fun for the athletes, but don’t you think it’s pretty important that your speed work make kids faster? So, if someone is selling a speed course, but they don’t get people faster, why buy it?

All too often, we do these things because we listen to what they say or their graphics or videos look cool, but do they do what they say they actually do and is it successful? If people will share more of those “before/after numbers” (like I do here with our 1×20 work—sorry in advance for how awful the audio is—and also here) and/or we ask those questions, it will lead to much better dialogue and greater growth in our profession. If we tie that in with going to the actual source of the information—meaning the person or people who actually came up with the means or methods we are discussing—a lot of fake confusion revolving around how to improve performance would evaporate.

CVASPS: What advice would you give a coach to improve their knowledge as a process of continuing education? By this, I mean, can you point our readers in a few concrete directions to find the scientific and practical information to improve the methods used to improve performance?

Jay DeMayo: Piggybacking off the last question, I think it is to go to the source. All too often, we inadvertently bastardize someone’s life work because of our own biases in training. It’s just human nature to see what we see through our own eyes and put our own little flavor on it. With that in mind, though, you see people doing things differently than what the work of the people who established the means and methods actually states. If you are using the name of their method and not doing it the proper way, it’s not their method.

If you are using the name of somebody’s method but not doing it the proper way, you’re not using their method, says @CVASPS. Share on X

A great example of this is HICT, a method that was made famous in Joel Jamieson’s book, originally coined by Dr. Viktor Seluyanov. High-intensity continuous training is performed to help increase the mitochondrial density in the type II fibers, but to activate the type II fibers, what is required? Super high loads, or MAX Intent. But when you look at people who post they’re using this method on “The Gram,” you see people doing step-ups with bands looking so bored and discontent that they could fall asleep. That is not HICT; that is a waste of time and an insult to Viktor’s work.

I probably shouldn’t take things like this as personally as I do, but I do because most of the things that I see people confused about are means and methods that were presented on at The Seminar: how to progress the jumping exercises, what depth jumps and plyometrics are, what extensive vs. intensive means, truly understanding simple energy system development… Oh, and don’t get me started on 1×20. These are all things that were presented on by the people who are the experts on them and who built these systems. They’re things that have been really misunderstood because people listened to someone’s interpretation of someone else’s work rather than going to the source.

Once you have gone through what the originators have said, sure, dig a bit, talk with others who use the method, and see what they see, but let’s keep in mind that most of their first names are “Doctor” for a reason. Chances are they figured out why their way is better than ours at some point already. Not saying that there may not be a better way, just saying that more often than not, they’re right.

CVASPS: For readers unfamiliar with your history, can you provide some background on your niche in the world of athletics, the educational/career path you took en route to your present role, and any notable publications, courses, or products you have available that you’d like to direct readers toward to dive deeper?

Jay DeMayo: I’ve been very fortunate to hold the same position for nearly 20 years. I’ve been granted a lot of leeway to make mistakes and allowed to fall on my face a few times and really grow as a coach. Professionally, I’m the head strength coach for men’s basketball and tennis at the University of Richmond, where I get to work with some really awesome athletes and coaches.

We have put together an exceptional support staff in “The Q” that is truly forward-thinking and pushes each other to be better for the athletes we work with. Our “team behind the team” has really helped me regain my drive for personal and professional growth, so I owe them a lot.

I am also the head strength coach for NOVA Aquatics, where I work with a fantastic head coach and some really great swimmers. I’ve been fortunate to work with an athlete who went on to win an Olympic gold medal and another who won international championships. It must be something in the water (pun intended), because the club keeps putting out swimmers that make U.S. teams and high major college swim squads. I’m really fortunate to have been able to be a small part of it and watch the club’s growth over the past 15 years.

On top of that, I run Central Virginia Sports Performance or, as many refer to it, CVASPS. With CVASPS, we have a yearly event, The Seminar, that will be held at PLAE HQ in Canton, GA (Atlanta suburb), on July 21 and 22. I’m super excited about that and the opportunity everyone at PLAE is providing for us to bring the “200-Person Round Table and BBQ” to a sensational location. Alongside the event, we have a yearly publication, The Manual, which is 10 unique chapters from past contributors on a vast array of topics. Finally, we also have a podcast that has been on and off, but we are back to putting out episodes at the moment. You can find that on your preferred podcast platform under “CVASPS.”

CVASPS: Can you provide a sneak peek at the topic you will be covering at The Seminar, as well as a few useful takeaways on the presentation for those who may not be able to attend?

Jay DeMayo: In my presentation, I will give a breakdown of how we practice reverse engineering in our programming. I plan on giving the 15,000-foot view and then taking a step back and walking through 2–3 specific examples. This will hopefully help coaches:

  1. Understand how to utilize this thought process in their practice.
  2. Provide examples of how we did it for them to recycle or alter for their setting.
  3. Teach the principles we follow to help regress movements to improve transfer.

CVASPS: What’s one question or topic that no one ever thinks to ask you about (or tends to be under-discussed across the board), and what would you like to add on that subject?

Jay DeMayo: I think the biggest things coaches need to talk about more are things outside of coaching, but more specifically, ways we can be better financially. I spoke about it in the last Freelap Friday Five I had the opportunity to participate in. The better your finances are in order, the better a coach you can become because you’re not afraid of the “what ifs.” There are a bunch of different avenues to explore and ways we can better ourselves in that realm; you just need to find the one that is best for you, do your homework, and grow from there.

Squat Lift

The Goldilocks Rule of Post-Activation Potentiation

Blog| ByDrew Hill

Squat Lift

Imagine you’re walking into a store with a list in your hand, determined to get out as fast as possible. You don’t want any distractions or impulse buys to take up your time or money—but right as you hit the first aisle, a uniform-clad employee shoves a pamphlet in your face. Agitated, you furrow your eyebrows and glance at it quickly: How dare they try and upsell me! I know what I need. And then you realize smack dab on the front page are all the things you came there for, with coupons to cut your bill way down.

In our haste, we sometimes ignore all of the ads and discounts around us because we have a “mission.” In our hurried state, we become like Goldilocks, who ignored the warning signs and tried to get a good meal and bed, but was set on fire and eaten by anthropomorphic bears instead (according to the 1831 version of the story, and I promise I have a reason for bringing this up).

Post-activation potentiation (PAP) takes the training we would already do and gets us the results we want, faster, says @endunamoo_sc. Share on X

As coaches, we can be unwilling to realize our mission has put us in a bear’s den when a great opportunity for nourishment and recovery lies elsewhere. That’s how I like to look at the training phenomenon known as post-activation potentiation (PAP). Many of us are so focused on certain aspects of our training—such as optimal squat depth or whether we should use a trap bar—that we aren’t experimenting with a system that affects the real reason we train athletes: getting faster and more powerful. PAP takes the training we would already do and gets us the results we want, faster.

You’re Doing What to My Potentiation?

We’ve all had good days, bad days, and just plain okay days. Too hot, too cold…and sometimes just right, whether that be in the gym or just life in general. As you get older and wiser, you learn how to turn bad days into okay ones, and okay days into great ones. You can apply the same principle to training athletes. By manipulating things like warm-ups, exercise selection, and even intensities, we can create a “sweet spot” that maximizes the output that someone has available for that day.

PAP is a theory that prior activity can positively impact the performance of subsequent movements. Many coaches have already heard of this theory, but a layperson might ask, “Wouldn’t doing more activity make you tired?” After all, nobody ran a marathon and then magically dunked for the first time. The answer to your/my/their hypothetical question is, “It depends.”

Fatiguing muscle activity can decrease performance—however, stimulating contractions can enhance it. This is the Goldilocks effect of sports training. Too much activity and you get tired, too little activity and you waste your time, but just the right amount can create PR performances—and keep you from inferno bear consumption. The most common example of this is a heavy squat paired with an explosive jump: done under the right circumstances, this can result in lifetime best verticals.

You might be thinking that PAP sounds overly complicated and not your cup of tea, but I bet you a hot bowl of porridge that you’ve used the concept before and didn’t even realize it. Walk into any weight room, field, or court, and at the beginning of activity, you’ll find almost every single team WARMING UP. Dynamic warm-ups are a great way to improve the function of muscle as well as the subsequent performance—in other words, a very mild form of post-activation potentiation.

Or maybe you’re on the other side of this conversation, saying “Who doesn’t know about PAP?” It’s easy to pair like exercises and think you’ve got a winning formula, but what looks like a good workout complex to a casual bystander might not be the “just right” formula.

Strategies like French contrast training have become very popular, but there is an elephant in the room we need to address. Without tracking intra-workout metrics, you might be introducing more fatigue than potentiation.

Likewise, it seems that stronger and more developed athletes have a greater positive response to PAP than novices.1 So, breaking this out with your U12 soccer team may not be as effective as you thought. Even more, some research has shown that higher performers respond better to the PAP effect of isometric holds as well, while others have no effect at all.2 The novice training effect works in reverse when it comes to PAP strategies—the more trained you are, the better the improvement.

Not Too Hot

I’ve watched numerous videos online where coaches/trainers/influencers prescribe their workout routines trying to use the PAP effect. The flash and pizzazz of the videos look great, but that’s where the success typically ends. By overstimulating to make the workout look hardcore, the results are most likely an over-fatigued and underperforming athlete. This porridge is too hot.

If you don’t track the secondary movement metrics, you might never realize that the training you’re doing is actually not working out so well, says @endunamoo_sc. Share on X

If you don’t track the secondary movement metrics, you might never realize that the training you’re doing is actually not working out so well. The three biggest mistakes I see are always:

  1. Contrast Exercises without Adequate Recovery Times. This results in too much fatigue. If you’ve ever run a busy weight room, you know what it feels like to have athletes standing around and twiddling their thumbs. And you better gird your loins if the football coach walks in and doesn’t hear screaming and bars banging at all moments of the workout.
    Unfortunately, adequate PAP requires several minutes of passive recovery. It’s okay to stimulate the mind, but it’s very hard not to find something physical to do as well. Although it feels counterintuitive to do nothing, you can supersede baseline performances with longer rest periods. There is hope though. Lower-intensity/lower-duration movements like jumping seem to require less rest than sprinting movements.

  1. Wrong Stimulus for Desired Output. In most cases, an adequately heavy movement is required before the dynamically fast action. But it’s a fine line between heavy enough and too heavy. You can also utilize more power-based exercises or the right intensity isometric. In addition, most research shows that there is MASSIVE individual variance—meaning, what might work for a more-trained individual will have NO effect on a younger athlete.
  2. Poor Exercise Pairing. This may not be the end of the world, but it can result in subpar outputs. In theory, any kind of CNS-stimulating act should create systemic improvements—but, in practice, we want to make sure that we line up the square peg with the square hole and don’t just jam a triangle in sideways. In most cases, pairing like movements should yield the best results. The grey space occurs when we have an activity like a sprint, where a bilateral back squat or deadlift can yield huge improvements. It is up to the coach to track the output of the desired exercise and make sure the shapes line up.3

Not Too Cold

I know that most of us aren’t small-engine mechanics, but if you ever struggle to get your lawnmower started, grab a can of carb/choke cleaner and blast it into the choke valve shaft. Once all of the gunk has been cleared, you’ll hear that engine crank. A lot is happening on the inside of that engine, but all you need to know is that this works.

Choke Cleaner

But, as strength coaches, we might need to know exactly what’s happening inside our athletes when we implement certain training strategies. PAP has been attributed to the phosphorylation of myosin regulatory light chains, which makes actin and myosin more sensitive to Ca2+. The potentiated state has also been attributed to an increase in α-motoneuron excitability, as reflected by changes in the H-reflex. In laymen’s terms, the correct exercise can act like a carb fluid that kickstarts performance into overdrive.

To take advantage of this, we can improve the power or velocity of an athlete over time by training at a higher level each workout. For example, if athlete A has a peak vertical at 23 inches and they perform traditional plyometric work, they might perform a series of jumps between 19 and 21 inches. Meanwhile, athlete B has the same vertical but uses a PAP strategy and performs their jumps between 20 and 23 inches. Which one will adapt to greater peak power?

Most likely the one jumping higher: athlete B.

We can improve the power or velocity of an athlete over time by training at a higher level each workout, says @endunamoo_sc. Share on X

By contrast, athlete A missed out on dozens of jumps closer to their peak vertical. We adapt to what we do, and jumping higher requires high jumps. This porridge is too cold.

It’s My Activation, and I Want It Now

I teamed up with my local university in 2019 to produce a study that asked what the ideal percentage of an athlete’s squat 1RM needed to be to acutely improve vertical jump performance. We concluded that 75%–80% 1RM was the greatest and most consistent intensity for our goals. While some research suggests up to nine minutes of passive recovery is effective, we opted for the more realistic one minute of sitting.

During this data collection, I realized that I had my own faux pas in training. My athletes’ recovery time wound up being closer to 30 seconds—roughly the time it took for them to walk to their next station. And I know that I’m not alone in making this blunder—with so much we want to accomplish, it’s hard to sacrifice time for sitting around. To make sure we find the bed that is just right, I’ve coined the three I’s of PAP:

  • INTENSITY—most power-based research suggests that 70%–80% of the 1RM is best for standard strength and power Olympic exercises, or 35%–40% of standard strength exercises done as a ballistic or plyometric.
  • INACTIVITY—a minimum of one minute of doing NOTHING is required to stimulate performance, but if you have the time, you can wait up to 16 minutes for more taxing activities like top-speed sprinting.4 (You will have to decide based on your resources and the secondary movement’s output.)
  • INFLUENCE—we should be pairing movements that will positively affect each other and not just take up time. If your goal is to improve max vertical jump, pairing bench press with box jumps might not be the right call.

PAP Three Is

The Newest Trick in the Book

In August 2018, during the NFL’s Brown’s football warm-ups, the world was humored by Assistant O-Line Coach Bob Wylie when he said, “Did you know, World War I and World War II, all those guys that fought in that war…they did…none of this fancy [expletive]. And they won two World Wars. Do you think they were worried when they were running across Normandy about [expletive] stretching?” Coach Wylie’s opinion on properly warming up before activity is one that died with the old guard years ago. The world of sports has evolved past this instance of ignorance, but we still have some muddy waters to traverse.

The new “dark age” we need to get out of is ignoring the benefits of a good pre-game lift. I asked a few coaches why they wouldn’t do pre-game lifts or even day-before workouts, and the most common answer was “We don’t want to be sore.”

This would make sense if you don’t weight train during your season, but I’m going to assume this isn’t the case for most of us. Long-term PAP is often referred to as post-activation performance enhancement (PAPE) to distinguish between short-term training gains and long-term sports improvements.

When done correctly, resistance training can be a primer to enhance performance on game day. Training as close as six hours before a game can have significant improvements on your team’s performance.5 But if that makes your football coach uncomfortable, that’s okay; you can even train the day before and still see some enhancement in things like power and sprint times.6 The catch is that most of the training should be lower volume, moderate intensity, and power based.

Don’t Overcomplicate Things

In college, we all go through a program or take a test called “Practicum.” It’s like taking a nurse out of the classroom and putting them into a hospital setting to see what they’ve learned (also known as clinicals). Below is a quick example of how to take PAP and PAPE from strategy to application.

There are many ways to use PAP in your training; I just recommend you use SOME form of metric monitoring. It’s tempting, but don’t fall victim to overcomplicating a simple thing, says @endunamoo_sc. Share on X

There are many ways to utilize PAP in your training, but my only recommendation is that you have SOME form of metric monitoring. It is tempting, but don’t fall victim to overcomplicating a simple thing. There are other systems to utilize PAP or PAPE, some of which are called contrast training. (French contrast training is a popular model.) For most of our athletes, LESS is MORE, and adding layers could negate some of the benefits.

To determine whether you chose the right system or adhered to the three I’s of PAP, you simply need to track how the secondary movement is affected. If you see a drastic decrease in the desired output, you might need to adjust the rest length, the exercise volume/intensity, or both!

PAP

Squat x 3 @ 70%

Rest x 1 minute FULL

Max Effort Jump x 5 (An easy way to track this is with a box jump set at a specific height -or- an object touch like a rim -or- jump mats)
*Complete 3 to 5 rounds 
PAP Example

PAPE

Trap Bar Jump 3×5 @ 40% (DL MAX) Rest x 1–2 full minutes between bouts
Back Squat 5×1 @ 70% (explosive intent) Rest x 1–2 minute between bouts
Bench Press 5×1 @ 70% (explosive intent) Rest x 1–2 minute between bouts
PAP Training

This One Is Just Right

Utilizing PAP or PAPE cannot be your entire training philosophy, but you shouldn’t ignore the nice employee trying to hand you the deal of the year because a checkout line is right there. We didn’t even talk about long-term progression or how to include conditioning or other qualities a good S&C program would need. But PAP is a tool that can help most programs get more out of their training.

PAP is a tool that can help most programs get more out of their training, says @endunamoo_sc. Share on X

A quick Instagram search turned up ZERO accounts that have post-activation potentiation in their username. (I have found this the best way to determine whether something is trendy and has a shelf life.) That being said, if we can implement PAP principles within our training, we might find the perfect porridge to get the results our athletes are growling for. Goldilocks might not have had the ending she wanted, but we S&C coaches have a real shot at making our bears, er, head coaches, say “JUST RIGHT.”

Odd Object Training

Six Ways to Program Training with Odd Objects

Blog| ByBrandon Holder

Odd Object Training

The implementation of odd object training has become more common and popular over the years. What was once reserved only for those in the underground world of warehouse and garage-style gyms can now be found in your standard commercial gym and the most prestigious collegiate and professional weight rooms.

When considering odd objects, some of the primary forms available are sandbags, kegs, tires, kettlebells, stones (or heavy medicine balls to replicate), ropes, and other fat grip pieces of equipment. These tools can be used in countless ways to improve upon and build a well-rounded training program.

Odd objects are versatile enough to place them within any training program and can be effective tools for novice, intermediate, and even advanced trainees. Share on X

This increasing popularity of odd object training is due to several benefits. From developing total body strength to tremendous amounts of grip strength, these pieces of equipment are true developers of applicable “functional” strength. They are versatile enough to place them within any training program and can be effective tools for novice, intermediate, and even advanced trainees.

Fundamentals

Using odd objects to train the fundamental movement patterns is a fantastic new way to stimulate these exercises away from the barbell. In some cases, training the fundamental movements with odd objects can even be easier in comparison to their barbell-based counterparts.

For example, teaching a novice how to squat correctly while hugging a sandbag will train and check off many of the requirements of the squat, such as trunk tension, proper posture, and hip mobility, yet require even less upfront teaching than getting under a barbell. Not to mention that they’re probably handling more load than they would when training technique with an empty barbell. This serves as a great prerequisite for when they do get under the barbell, putting them in a much better starting position, figuratively and literally.

Looking at performing the exercises, they can be interchangeable with multiple pieces of equipment. However, some may be better suited to use than others just from the position or leverage that the equipment may offer.

1. Squats

Sandbag Squats

Performing squats with a chaotic piece of equipment like the sandbag is great for developing stabilization. It offers a different challenge with every rep as the load continuously shifts around.


Video 1. Sandbag squats can be performed from the bear hug, Zercher, or shouldered position. 

Kettlebell Front Rack Squat

The kettlebell front rack squat is a challenging and effective squat variation to build up the upper back muscles and force the athlete into perfect positioning. This exercise often surprises people with how difficult it really is, even when just performing with a moderate set of kettlebells.


Video 2. This exercise can be performed with a double front rack or single front rack to train the trunk in an off-loaded position.

For younger or less-experienced athletes, both exercises are great to master before moving on to the barbell squat.

2. Hinge

Bear Hug Good Morning

Bear hugging a sandbag, keg, or any other odd object tight to the chest when performing the good morning develops the entire posterior side and grip. This exercise is especially beneficial for the mid back and trains muscles your athletes didn’t even know they had.

Focus on keeping the load secure to the body when performing the exercise, and a little load goes a long way with this movement.


Video 3. Odd object good mornings and RDLs

RDLs

A secondary option for the hinge would be to perform Romanian deadlifts with the implement in the hands. Whether it be a sandbag, stone, or other option, the chaotic nature of the implement creates a greater challenge to perform this otherwise standard exercise.

3. Press

Keg/Sandbag Overhead Press

Pressing a keg or sandbag overhead challenges the stability of the shoulders and trunk as the weight in the load shifts throughout the exercise. The keg’s thickness will alter the overhead press’s starting position, but a neutral grip position helps allow for a smoother technical finish.


Video 4. Overhead press with a keg and a sandbag.

Tire Partner Battle

The tire partner battle allows you to get some horizontal pressing into the program, and you can use it as a great finisher or to conclude a warm-up with a highly driven neural exercise.

With a partner or coach, the tire will start upright and be forcefully chest-pressed back and forth for the set reps or time duration. The entire body will be involved, but primarily the muscles of the upper body to accept and redirect the heavy tire back into your partner.

4. Pull

Rope Pull-Ups

Pull-ups are already tough, but adding a rope to perform them takes it to an entirely new level. Rope pull-ups are not only the ultimate test of grip strength but also help develop the upper body and trunk. After performing a set, athletes often mention how their midsection is sore from the maintained brace when performing!

You can also use a rope to perform additional exercises such as inverted rows, rope rack climbs, or full rope climbs, like gym class back in the day.

Fat Bar Bent Rows

Fat bars are a little more uncommon than some of the other pieces of equipment found in this list, but that shouldn’t limit you from their benefits. A strong substitute is fat grips that you can buy and use on almost all of your pieces of equipment.

Using a fat grip will cause the athlete to squeeze more, creating more tension and overall muscular and neural involvement throughout the entire body.


Video 5. Using fat bars with an exercise like bent-over rows is a great option, but the bars and grips shouldn’t be limited only to this exercise.

5. Single Leg

Single-leg training should also be used with odd objects.

  • Reverse lunges
  • Split squats
  • Step-ups

Similar to the squat, multiple pieces of equipment can and should be used, as well as various positions of holding the odd objects: bear hug, Zercher, shouldered, etc.


Video 6. Single-leg movements include step-ups, reverse lunges, and split squats with various odd objects.

6. Total Body Training

The durability of these pieces of equipment is perfect, enabling you to violently throw, drag, flip, carry, and do any combination of movements imaginable to train the entire human body.

When performing many exercises with odd objects, it’s necessary to use the total body. You can use these exercises as alternatives to the more technical Olympic lifts, and they are also better suited when training in a circuit or conditioning training session.

Shouldering/Up and Overs

Shouldering a heavy object or completing the movement by throwing it over the shoulder is great for developing forceful hip extension and a strong initial pull from the ground using the legs, trunk, and back.


Video 7. Shouldering exercises.

Weighted Get-Ups

One of the sneakiest and most challenging exercises, the weighted get-up, requires total body strength and coordination.


Video 8. The execution of the weighted get-up is easier said than done—hold an implement while sitting on the ground and *simply stand to your feet.*

When implanting this movement, I like to offer little insight, so it then falls on the athlete to problem-solve and figure out their own methods to get to their feet. Placing constraints on them—such as only allowing the use of one or no hands to stand—affects the pattern and difficulty of the exercise.

Tire Flips

While I am more selective with programming tire flips due to their technical requirements and ability to cause low back strain, it doesn’t take away from the fact that they develop brutal strength and total body explosiveness.

When performing the tire flip, it’s important not to pick it directly up off the ground but instead drive through the tire horizontally. This takes the pressure off the low back and is a more efficient way of flipping the tire as a whole. Once you get the tire up to your knees, you can use your knee and hip to get it vertical and finish forcefully with the upper body.

Tire Sledges

Hitting a truck tire with a sledgehammer works to develop rotational strength in the trunk, hips, and shoulders, as well as develop the grip. This may require some upfront coaching—and coordination is helpful—but once you have it down, athletes can perform this exercise in multiple different planes, such as lateral and cross-body swings.

Keg Clean and Press

Taking a keg from the ground and putting it overhead is a challenging exercise that can humble even the strongest athlete if they’re not prepared.


Video 11. Just like a standard clean and press, the hips are required to bring the keg overhead while keeping your midsection braced and body rooted as the weight in the keg shifts.

Fat Bar Complexes

Using a fat bar to perform complexes will develop unreal grip strength while also strengthening and developing the entire body, regardless of the exercises chosen.

Complexes shouldn’t be limited to only certain exercises or rep ranges, and I would recommend a balance of upper body, lower body, and low to high rep ranges involved.

An example of this complex would be performing five reps of each movement before putting the bar down for three total sets:

  • Overhead press
  • Bent row
  • RDL

Fun/Challenge

There is something inherently more fun and stimulating about training with odd objects. When performing the exercises, it’s much harder to just go through the motions and perform with a lack of not only physical engagement but mental engagement as well.

Speaking with several athletes and clients over the years, utilizing these pieces of equipment has completely altered training sessions and sparked spontaneous competitions. They viewed the objects in front of them as a challenge and a self-confidence booster.

Additional Resources to Check Out

Dinosaur Training – Lost Secrets of Strength and Development, by Brooks D. Kubik

The original book on odd object training, Dinosaur Training, details how to train with odd objects such as sandbags, logs, fat bars, and more. This book set the foundation for many strength and conditioning coaches today. It should be required reading if you’re interested in learning more on this topic (or just about strength and conditioning in general).

The Encyclopedia of Underground Strength and Conditioning, by Zach Even-Esh

I consider Zach Even-Esh to have helped pave the way for strength and conditioning today, as well as being a driving force on the use of odd objects in training. Much of what was brought up in this article was inspired by Zach and by my following his work from a very young age.

He has spoken on the subject for years. While he has several resources available on the subject, nothing comes close to his actual encyclopedia of odd object training, amongst other training topics he covers in the book.

Final Takeaway

Training with odd objects exceeds the hype. Using movements outside the standard strength training tools will progress the fundamentals, build total body strength, and create a more meaningful and engaging session. You are now more likely to find these pieces of equipment wherever you may train, and you should integrate these odd objects into your training sessions to take athletes to the next level.
