Diving in Deep with Proteus Analytics

Today's guest post comes from physical therapists Will Waterman and Tanner Allen.

In an analytically driven world, finding a way to capture coveted and seemingly intangible qualities of athletes is highly sought after. Back in January, Cressey Sports Performance - FL began looking into Proteus as a potential way to bridge the gap between training programs and objective measures (see the article Taking Proteus for a Spin). Following Proteus Motion’s release of the General Power Test in June of this year, we decided to apply this testing to CSP-MA and their college summer program in hopes of finding out what role power plays in a collection of athletic qualities. Today, we'll reviewr the results of our power testing on athletes and discoveries that may have an impact when creating and enhancing individualized training programs for our athletes.

The Power Test report shown above is an output shown on the Proteus system’s touchscreen after 17 exercises are performed in under 5 minutes. The data is tracked for each player over time, and can also be printed, shared by email, or accessed remotely through a web login.

Before we dive in, it will be helpful to know a little bit about the Power Test listed in the video below as well as the structure of our small study and what we intended to capture. The CSP-MA college summer program consisted of 14 collegiate pitchers tested 3 times over a 6 week period (beginning, middle, and end). Normally, it would have been a longer training period and sample size, but COVID-related restrictions thinned the herd a bit and led to a shortened timeline. We looked at General Power Test reports utilizing Proteus and pitching velocity captured by Rapsodo. This 3-minute video will briefly explain the General Power Test.

The five primary goals that we intended to identify utilizing Proteus throughout this study included:

● Showing objective improvements in CSP’s training with test and retest findings
● Establishing normative power profiles that quickly help identify areas of weakness among athletes
● Finding intra-body norms for push vs pull as well as unilateral vs bilateral comparisons and imbalances
● Identifying other metrics that Proteus captures to create more specific tests in the future to further enhance its capabilities
● Identifying correlations between Proteus and pitching velocity

Following the completion of the 6-week study, we were able to collect normative data ranges for our test group sample. This allows coaches using Proteus to analyze patterns in search of the lowest hanging fruit to address in training. Through providing easy-to-digest information, this helps coaches identify outliers as well as over and underperforming athletes within a group.

In the picture below, you are able to see a breakdown of how an individual improved from his 1st session at the beginning of training to his 3rd session following completion of CSP training over the six weeks. The dotted red line depicted below represents the average scores across the entire test group, allowing for simultaneous comparison. This ultimately allows for quick recognition of areas in which a specific athlete has under or over-performed compared to their age group norms and peers.

The addition of this quantitative and analytic test of power output can then be compared with the rest of CSP's assessments to create a comprehensive view of how an athlete is currently performing, how they are improving, and which areas require further development. This comprehensive approach lets strength coaches and other healthcare professionals understand how structural and functional presentations may affect power output.

Next, I want to show examples of interesting findings related to intra-body comparisons along with unilateral and bilateral imbalances discovered within the baseball population using Proteus.

*Disclaimer: These are based on small sample sizes, so by no means should these be assumed as a one size fits all.

1. Greater power in dominant side rotation compared to non-dominant side rotation

A unique attribute of Proteus is the ability for rotational qualities to be tested. One would think that these athletes have an increased amount of power rotating towards their non-dominant side (e.g. throwing or hitting a baseball), but our findings were the opposite. In our study, 7 out of 10 right-handed pitchers showed an average of 5.6% increased power output rotating towards their right (dominant side). After considering what could be the reasoning for this metric finding, we generated five hypotheses:

● Proteus motion is concentric in nature with the testing protocol performed in a non-counter (“non-plyometric”) fashion which does not allow the athlete eccentric loading prior to the task. With natural movements such as throwing a baseball, an athlete naturally pre-loads prior to rotating towards their non-dominant side. Due to the testing design, this could provide motor interference to what would normally be a natural movement to them
● PRI (Postural Restoration Institute) considerations, as Left AIC patterns are commonly seen throughout the baseball population.
● Years of eccentric stress from decelerating on their right side obliques improves strength on their dominant side over time.
● Limited thoracic rotation or decreased testing ROM.
● Simple fatigue as these tests were completed following max effort Rapsodo bullpen sessions.

Note from EC: we've effectively eliminated the last point (fatigue) as a consideration in the extensive testing we've done in our professional baseball players this offseason. The differences have been just as pronounced (if not moreso) in this population, and without a bullpen before testing.

2. Greater power in non-dominant side lateral bound compared to dominant side bound

In this example, imagine a right-handed pitcher being more powerful in his lead leg compared to his dominant right leg (his drive leg in pitching delivery) with a frontal plane movement like a Heiden. This group showed a 4.5% bias in power on the non-dominant leg (i.e., right handed pitcher was better pushing off from the left to go to the right).

One hypothesis might again be explained by the Left AIC pattern as described by PRI. Many athletes are subconsciously unaware that they tend to jump off of their left leg when going for a layup, jumping for a ball, or cutting for example. PRI explains this as a consequence of the L AIC pattern, as those with that pattern tend to be more comfortable in LOADING via standing or landing on their right leg and tend to be more proficient with EXPLODING or launching movements off their left leg. PRI explains this as a common implication of the Left AIC pattern, which is a pattern of being over lateralized on the right side in the frontal plane. This finding might be an indication of that pattern, as most of the athletes were biased towards having more power jumping off of their non-dominant left lower extremity. Greater sample sizes in the future will help us confirm or deny this finding.

3. Unilateral pressing and rowing movements are more powerful than bilateral variants by 4%

The likely reasoning for this finding is the rotational sport athlete’s ability to tap into the transverse plane component of these movements. Since Proteus Motion utilizes 3D resistance, the athlete is not confined or restricted by specific planes of motion (frontal or sagittal) as they are in other traditional training methods (e.g., shoulder blades being pinned down on a bench). This allows for proper scapular protraction and retraction to take place throughout the test.

In the picture below, you can see an example of points 1&2, of a right-handed pitcher showing both qualities.

Besides intra-body comparisons, we also looked at comparisons of Proteus data to pitching velocity to see if we were able to identify what movement qualities may translate to throwing performance. We used Rapsodo to capture pitching velocity, and then cross referenced it against all metrics that Proteus measures, even those not provided in the General Power Report (which only provides power data and does not give breakdowns of acceleration, deceleration, and other metrics). Whadiscovered was that average dominant side acceleration in (m/s2) had a strong correlation with pitching velocity showing a R-value of .76, and P-Value of .003 during Session 3 testing. This was an intriguing finding and one that has started future planning of a potentially better and more specific baseball related Power Test.

Dominant Side Acceleration = Average Acceleration of all dominant side movements except using non-dominant trunk rotation instead of dominant side.

In conclusion, here are the key takeaways the team has learned this summer and how we plan on implementing our findings into future iterations of CSP tests:

1. We can use Proteus for benchmark testing to help us identify areas of weakness or strengths in each athlete. This information can help to quickly adapt individualized training programs to improve training efficiency and outcomes.

2. In addition to measuring power in (Watts), we want to incorporate acceleration (m/s2) into our future readings and reports as well as provide a comparable metric across different resistances. This can be extremely beneficial for coaches when tailoring programs for individuals to allow for appropriate starting points along the strength/speed or speed/strength continuum (e.g., medicine ball movements and weight best suited for the individual).

3. Measuring the difference in output of an individual between using non-counter movements (which is currently how the General Power Test has been performed) vs counter-movements such as plyometrics. We can then compare the ability of the athlete to create elastic vs reactive qualities of movement. By allowing for small eccentric loads while transitioning between movements during the amortization phase, we can assess different metrics of power and acceleration of a plyometric and compare it to pure concentric drive when there is no or low loading phase present. Prior to Proteus, coaches relied heavily on visual observations and movement patterns to differentiate plyometric and concentric biased movements. Proteus will assist and enhance coaches targeted interventions specifically for upper body and core movements.

Overall, the summer study that Proteus and CSP MA performed had huge success in identifying the progress of players, improving target metrics for specific populations, and enhancing testing qualities. On average, athletes had a 25% improvement on the General Power Test from Proteus between sessions 1 and 3. Pitchers also improved on 3+ mph on their fastball velocity on average following their six-week training camp (84 -> 87 mph). Proteus Motion offers a lot of different benefits for both short term and long term development of athletes by capturing objective data throughout an individual’s strength and conditioning journey. Proteus provides CSP a unique way to objectify future evaluations, program development, readiness testing, and monitor training and rehabilitation.

Variation Without Change

I can recall the late Charles Poliquin speaking many years ago about the concept of "Variation Without Change."

When I first heard this phrase, I believe he was referring to the stimuli needed to induce muscular hypertrophy. If you wanted bigger lats, you might do chin-ups (supinated grip) for a month, then neutral grip pull-ups for a month, then regular (pronated grip) pull-ups for a month. Simultaneously, the focus might shift from sets of 8-10 reps to sets of 4-6 reps.

The principle was simple but effective: if you do what you've always done, you'll get what you've always gotten. However, subtle variations to the approach - without throwing the baby out with the bath water - were important for providing for longer term adaptation while not developing overuse injuries or mind-numbing boredom.

To me, "variation without change" is a subcategory of periodization. The overall training priority might be adjusted from one mesocycle to the next, but some of the exercise categories can remain relatively consistent. Medicine ball work is a good example; we use it in a variety of ways throughout the year.

In-season, for a right-handed pitcher, we might do left only rotational med ball scoop tosses to counteract some of the crazy imbalances that can emerge in such a unilateral dominant sport.

In the early offseason, we might utilize anti-rotation drills to give athletes reminders on where to find rotation without being so aggressive that it beats them up at a time of year when they should be recovering.

As the offseason progresses, we can get to more drills where we attack rotation - and then build in sequencing that incorporates momentum.

Finally, as the season approaches, we can make the drills more open-loop by having athletes either respond to a "go" command or have to "receive and release:"

As you can see, all of these exercises fall under the same broad heading, but are each categorized slightly differently. In our recent podcast with Bill Parisi, we discussed how pronounced fascial changes take 18-24 months, so you need variety to keep athletes engaged while still incorporating these long chain, multijoint movements at varying speeds and loads.

In the weeks ahead, I’ll have a few new articles to dig deeper on the topic of rotation. In the meantime, however, I would strongly encourage you to check out my new Medicine Ball Master Class. I created this new resource in collaboration with Athletes Acceleration, and it’s on sale for 20% off through this Sunday at midnight.

Accidental Strength and Conditioning Success

I often joke that some of the biggest training successes of my career came about when I was trying to develop one athletic quality, but actually wound up accidentally developing something else that yielded a great return on investment. Medicine ball training might be the absolute best example of this.

Back around 2007, I started implementing high-volume medicine ball training: both rotational and overhead work at least three times per week with our baseball athletes. There was some decent research on how it could positively impact throwing velocity and bad speed, but I found the training protocols in those studies to be really underwhelming. It was just a lot of “three sets of 10 reps” monotony and relatively basic and unathletic drills. by getting more creative with exercise selection, I felt that it would yield bigger returns on power development while keeping athletes more engaged. And, it accomplished both goals.

What I didn’t realize at the time was that it was also simultaneously creating much better movers. You see, all that medicine ball training was chipping away at some important adaptations we needed in the fascial system to prepare athletes for elasticity in more extreme positions of rotation. By manipulating load, the extent to which we pre-loaded, and where we sat on the force-velocity curve, each rep was helping athletes to develop adjustability, something that’s crucial to withstanding the unpredictable nature of many sports.

And, the truth is that what we learned from training with medicine balls, gave rise to open mindedness in similar avenues. The Versapulley allows us to train higher load, lower velocity rotation with more eccentric overload. 

Proteus allows us to train both high and low load rotation with a concentric focus.

Rotational work on traditional functional trainers seems to be a happy medium between the two. I’ll have their place, but you just need to know what to train.

In the weeks ahead, I’ll have a few new articles to dig deeper on the topic of rotation. In the meantime, however, I would strongly encourage you to check out my new Medicine Ball Master Class.

It goes without saying that scapular control - or the ability to position the shoulder blades appropriately - is absolutely essential to safe and effective upper extremity movement. In order for that to occur, though, the shoulder blades have to start in the right position. With respect to scapular rotation, "neutral" posture has the shoulder blades sitting at 5 degrees of upward rotation at rest. In the picture below, the black line represents where he should be in terms of upward rotation, but instead, you'll see that he sits in about 20-25 degrees of downward rotation (for the record, there are a number of other things wrong with this posture, so this is only a start!). The problem with starting in this much downward rotation (or any downward rotation, at all) is that it's like beginning a race from 20 yards behind the starting line. When the arm starts to move up, the shoulder blade needs to rotate up to maintain the ball and socket congruency. If it starts too low, it can't possibly be expected to catch up - so the ball will ride up relative to the socket, regardless of how strong the rotator cuff is to try to prevent that superior migration. You'll wind up seeing irritation of the rotator cuff, biceps tendon, labrum, or bursa if it's left unchecked. Step 1 is to simply educate people on where the scapula actually should sit, and step 2 is to work on training from that correct new starting position.
