Random Thoughts on Sports Performance Training – Installment 35

It's a new month, so here's a new installment of Random Thoughts on Sports Performance Training. This month, it won't be quite so random, as I want to hone in on shoulder stuff because today is the last day to get $40 off on my popular resource, Sturdy Shoulder Solutions. Just head to www.SturdyShoulders.com and enter coupon code OFFSEASON19 to get the discount.

Now, let's get to the new content:

1. The neck is the easiest place to start with cleaning up shoulder movement.

I've written a lot in the past about how our arm care programs work proximal to distal, meaning that we focus on the center of the body before the extremities. Usually, the right proximal changes yield immediate distal improvements both via reducing protective tension and reducing stiffness in the muscles we're trying to "overpower" to create good movement. Usually, though, when it comes to proximal changes, folks look at the thoracic spine and rib cage only. In reality, the cervical spine ought to take precedence over both of them - particularly because all the nerve of the upper extremity originate from the brachial plexus, which ranges from C5 to T1.

Fortunately, while it might be anatomically correct, coaching optimal positioning in the neck is actually very simple in the context of weight training and arm care drills: get it to neutral and keep it there. In 99% of cases, that means getting people out of upper cervical extension, which fires up the levator scapulae (which competes against all the scapular upward rotation we want). Here's a video that walks you through what you need to know:

The thoracic spine and rib cage are sexy right now, but the cervical spine is an older, reliable option for cleaning up movement quickly in just about everyone.

2. Whenever possible, get core control integrated in your arm care drills.

I often come across arm care protocols that literally have athletes laying on a table for 30 minutes worth of "exercise." This not only leads to a disengaged athlete, but also overlooks the fact that the entire kinetic chain needs to be synced up to keep a shoulder healthy. We'll often use predominantly table-based exercises in month 1 to make sure athletes are picking up the technique in a controlled environment, but in almost all scenarios, these table drills are actually "fillers" between sets of strength training exercises that have the athletes up and around in the gym.

More importantly, after that first month, I try to make sure that at least half of our arm care exercises are done separate from the table. Maybe we do our horizontal abductions in a side bridge position, or integrate more bottoms-up carries or bear crawls for serratus activation. Perhaps the prone trap raises take place on a stability ball, or we shift to a TRX Y instead. Or, we could move the athlete to half-kneeling, split-stance, or in a rear-foot elevated position for their 90/90 external rotation holds.

Regardless of what we choose, the buy-in from athletes is definitely better - and just as importantly, the resulting training effect has a more specific carryover to sporting success.

3. Yet another study reminds us that GIRD is a measurement and not an actual pathology.

Glenohumeral internal rotation deficit (GIRD) was all the rage in the baseball sports medicine community for decades. Unfortunately, what many practitioners fail to appreciate is that GIRD can be a completely normal finding as long as an individual's total motion is symmetrical between throwing and non-throwing shoulders. We expect to see less internal rotation and more external rotation in a throwing shoulder because of retroverion in the throwing shoulder; the arc is just shifted. Here's a glimpse at what it looks like:

 

Today is Day 12 of #30DaysOfArmCare. Thanks to #Tigers pitcher @adamrav12 for the assist! Key takeaways: 1. Retroversion is a common finding and throwing shoulders. It gives rise to greater lay-back at max external rotation. 2. The more passive range of motion you have, the more consistently you must work to maintain active stability of that ROM. ROM without stability is injury risk. 3. Perform your cuff work in the positions that matter - and keep in mind that individual differences in passive ROM may be present. 4. Don't stretch throwers into external rotation, especially if they already have this much lay-back! Follow #30DaysOfArmCare and @cresseysportsperformance for more tips to keep throwing arms healthy. #cspfamily #armcare #baseball #mlb

A video posted by Eric Cressey (@ericcressey) on

Anyway, we are now at a point in time where more and more research on GIRD is out there, and it's pretty resounding: it doesn't predict injury as well as we once thought. And, more importantly, the opposite seems to be true: a loss of external rotation (usually from a combination of less retroversion and soft tissue limitations) equates to a greater injury risk. We need to get more of the "GIRD? So What?" literature into the hands of doctors who aren't familiar with the latest research, as many are still making "GIRD" diagnoses when they really are just range-of-motion measurements. I delve into this in great detail in the Sturdy Shoulder Solutions product, but figured another study reiterating the point can't hurt. This one - Relationship Between Glenohumeral Internal Rotation Deficit and Medial Elbow Torque in High School Baseball Pitchers - just found that GIRD wasn't associated with medial elbow torque in high school pitchers.

It's time to move on from GIRD!

4. If you're about to have shoulder surgery (or any surgery), get your Vitamin D checked.

For years, we've known that having an adequate Vitamin D status was important for a myriad of biologic functions. Perhaps the most well known among observations on this front was a 2015 study of NFL players that demonstrated that players with inadequate preseason Vitamin D levels were more likely to have suffered a lower extremity or core muscle injury. In fact, the likelihood of a hamstrings injury was 3.61 higher in those with inadequate vitamin D levels! As such, it's become a big area of focus in the nutrition and supplementation world for athletes.

However, I've honesty never heard of an orthopedic surgeon looking at it for those who either have chronic pain or are about to undergo a surgical intervention to treat a structural defect. We need to change that, though. A recently published study, Preoperative Vitamin D Deficiency Is Associated With Higher Postoperative Complications in Arthroscopic Rotator Cuff Repair, should help in that goal, though. Patients with pre-operative Vitamin D deficiency were 1.54 times more likely to require a revision surgery and 1.16 times more likely to require manipulation under anesthesia to overcome post-op stiffness.

Clearly, Vitamin D has a huge link to soft tissue health, so don't overlook it!

Random Thoughts on Sports Performance Training – Installment 34

It's been a while since I published one of these compilations, so I've got quite a "brain dump" for you today. Here goes!

1. Correct "overhead lifting" work is especially important for volleyball players.

After this Instagram post on the importance of correct overhead lifting exercises and coaching cues, a volleyball coach reached out to ask if I felt the same overhead principles would apply to volleyball as with baseball. His point was that the arm-swings are very similar, but being in the air may make a difference.

The short answer is that YES, these strength training principles would apply to volleyball players as well. I'd even argue they'd apply MORE for two reasons:

a. Volleyball players are generally a hypermobile population who can benefit even more from the enhanced motor control that proper weight training affords. Effectively, you're giving them stability through the (potentially excessive) range of motion they have.

b. The fact that the violent arm actions happen in mid-air means that you don't have a lower half to help with deceleration (as is the case with baseball players). The upper extremity needs to be that much more well timed and strong.

2. Red light therapy might be the next big sports science breakthrough.

I first came across red light therapy when some clients commented on how they'd utilized it for a variety of health and human performance initiatives - both focal (sore wrist) and diffuse (chronic disease). I dug deeper, and the research was super compelling. There are clinical applications for everything from sleep quality/quantity, to cognitive function, to migraines, to improved hormonal status, to exercise recovery. I've started utilizing it myself and I can see it becoming an integral part of our sports science approach at Cressey Sports Performance.

Joovv is a company that's at the forefront of the application of red light therapy, and they actually sponsored this week's podcast. If you head to www.Joovv.com/eric, you can learn more - and get a free gift with your purchase.

3. Sports are random practice.

I've been a big advocate for avoiding early sports specialization if your goal is not only a positive experience with exercise to build lifelong habits, but also long-term athletic success. Supporters of playing multiple sports rarely outline the specific "mechanism of action" for why multiple sports really works for development, though.

In my opinion, these benefits are mediated because most sports are the very definition of random (unpredictable and varied) practice. You change direction a ton with soccer, basketball, and tennis - but you're usually responding to an opponent or making strategic calls on the fly on your own. You use both hands and feet in unique ways. These experiences are markedly different than going out and just throwing 30 pitches off the mound in baseball, something that's entirely closed loop and only has a small amount of variance: blocked practice. The research on motor learning has clearly demonstrated that random practice outperforms blocked practice with longer-term retention tests and the associated skill acquisition.

Also, this should serve as a good reminder of how awesome playgrounds are.

Watching our daughters grow up has been a remarkable lesson on when to coach and when to take a step back and observe. Early on in parenting, you watch your kids take big tumbles where you think they have a concussion or torn ACL. Then they giggle, get back up, and keep playing. They’re far more resilient than we think, and it demonstrates that failure can often be the best teacher. Coaches - once you’ve established rapport and foundational movement quality with your athletes, seek opportunities for them to fail SAFELY in training, when there aren’t physical or psychological consequences. Parents - don’t protect your kids from failure. Rather, embrace its remarkable ability to teach and prepare them for whatever challenges await them in sports and life. Kids - don’t let your parents pave the way for you so that you avoid failure. And be sure to seek out coaches who consistently challenge you even if it results in the aforementioned failures. Swipe left to watch our girl crushing it on the playground in spite of a little taste of failure.💪 #cresseytwins #cspfamily #coaching

4. Our rotator cuff care approaches have three broad components.

I recently hopped on Mike Robertson's podcast, and one topic we covered was how we structure our arm care programs with respect to rotator cuff training. The whole interview is a good listen, but tune in at the 39:20 mark for this specific section.

Speaking of Mike Robertson, he's launching his own certification really soon. I've reviewed it and it's outstanding. He's got an early-bird list going to get folks a discount when it's launched; you can learn more HERE. Highly recommend!

Why I’ve Gotten Away from the “No Money” Drill (Video)

I first came across the "No Money" drill for scapular control and rotator cuff activation/strength back around 2008, and introduced it to a lot of people when I included it in my first book, Maximum Strength.

At the time, I was working heavily in the general population segment and hadn't gotten as entrenched in the baseball world as I am now. So, like a carpenter who only had a hammer, I started thinking everything was a nail - and logically applied the No Money Drill with all our baseball athletes.

The more time I spent around baseball players, though, the more I realized that the No Money Drill was actually feeding into the negative adaptations we saw in them: a loss of scapular upward rotation, lat stiffness, lumbar extension syndrome, etc. As a result, we've gotten away from the drill with most of our overhead athletes (depending on what we see in an evaluation). Check out this video to learn more:

Random Thoughts on Sports Performance Training – Installment 33

It's time for this month's installment of my random thoughts on sports performance training. In light of my ongoing 30% off sale (ending Sunday at midnight) on my Sturdy Shoulder Solutions resource (enter coupon code BASEBALL at checkout for the discount), I thought I'd focus this edition on the shoulder.

1. If you want a healthy shoulder, getting tobacco products out of your life is a good place to start.

The research is pretty clear: smoking is a bad idea (and an independent risk factor) if you're looking to stay healthy from a musculoskeletal standpoint, or have a good outcome in rehabilitation (whether conservative or post-surgical) . Here's an excerpt from a recent study with an excellent review of the literature:

"Cigarette smoking adversely affects a variety of musculoskeletal conditions and procedures, including spinal fusion, fracture healing, surgical wound healing, tendon injury and knee ligament reconstruction. More recently, smoking has been suggested to negatively impact rotator cuff tear pathogenesis and healing. Tobacco smoke contains nicotine, a potent vasoconstrictor that can reduce the blood supply to the already relatively avascular rotator cuff insertion. Furthermore, carbon monoxide in smoke reduces the oxygen tension levels available for cellular metabolism. The combination of these toxins may lead to the development of attritional rotator cuff tears with a decreased capacity for healing."

Many times, we're looking for the best exercise, rehabilitation protocol, soft tissue treatment, or volume amounts - but we really ought to be looking at lifestyle factors.

With a large baseball readership on this site, the logical next question: are these harmful effects also noted with smokeless tobacco (i.e., dip/chew)? The research is somewhat sparse, as it's harder to study a younger, active population than a bunch of middle-aged post-operative rotator cuff patients. However, it's hard to believe that the aforementioned carbon monoxide implications would cause 100% of the issues and that the nicotine would serve as just an innocent bystander. So if you're looking to check every box in your quest to stay healthy, it's not a bad idea to lay off the dip.

And, if healthy tendons aren't enough to convince you, do yourself a favor and read this article by Curt Schilling.

2. The 1-arm, 1-leg landmine press isn't a mainstay in your training programs, but can be a perfect fit in a few circumstances.

This looks like kind of a wussy exercise, but I actually really like it in two circumstances.

a. It's awesome in a post-surgery period when you can't load like crazy, but still want folks to be challenged in their upper extremity progressions. The single-leg support creates a more unstable environment, which means that antagonist activity is higher and there is more work going to joint stability than actual movement. In other words, it makes pressing safer.

b. Once we get to the inseason period, it allows us to check two boxes with a single exercise: single-leg balance and upper body strength (plus serratus activation/scapular upward rotation).

3. Posterior pelvic tilt increases lower trap activation.

I've written about it a lot in the past: core positioning has an incredibly important impact on shoulder function. Check out this study on how reducing anterior pelvic tilt increases lower trapezius activation during arm elevation and the return from the overhead position.

In my experience working with extension-rotation athletes (particularly baseball players), one of the biggest risk factors for shoulder injury is when the lower trapezius can't keep up with the latissimus dorsi. Just consider the attachment points of the lat in the picture below; as you can imagine, if you posteriorly tilt the pelvis, the lat is inhibited, making it easier for lower trap to get to work.

The lower trapezius is very important for providing posterior tilt (slight tipping back) of the scapula and assisting in upward rotation. These two functions are key for a pitcher to get the scapula in the correct position during the lay-back phase of throwing.

By contrast, the lat has more of a "gross" depression effect on the scapula; it pulls it down, but doesn't contribute to posterior tilting or upward rotation. This might help with an adult rotator cuff pain patient who has an aggressive scapular elevation (shrug) substitution pattern, but it's actually problematic for a thrower who is trying to get his scapula up and around the rib cage to make sure that the ball-on-socket congruency is "flush" when it really matters: the maximal external rotation position.

As such, you can say that the lat and lower trap "compete" for control of the scapula - and the lat has a big advantage because of its cross-sectional area and multiple attachment points. It's also much easier to train and strengthen - even if it's by accident. Upper body work in faulty core positioning (in this case, too much anterior pelvic tilt and the accompanying lumbar extension) shifts the balance to the lats.

We'll often hear throwers cued "down and back" during arm care drills. The intention - improving posterior tilt via lower trap activation - is admirable, but the outcome usually isn't what's desired. Unless athletes are actually put in a position of posterior tilt where they can actually feel the lower traps working, they don't get it. Instead, they pull further down into scapular depression, which feeds the lat-dominant strategy. This is why we teach almost all our throwers to differentiate between depression and posterior tilt early on in their training at Cressey Sports Performance.

3 Random Thoughts on Rotator Cuff Readiness

Both Cressey Sports Performance facilities are booming with baseball players coming back to start their offseason training, so it's the time of year when athletes are working hard to get their rotator cuff control back before they start up their offseason throwing programs. With that said, I've been thinking about some big principles on the rotator cuff readiness front.

1. In a broad sense, just above every rotator cuff exercise can be categorized in one of five ways:

a. Strength - this consists of manual resistance work and anything with cables at dumbbells; it needs to be loaded up and challenging.

b. Timing - this consists of drills like 90/90 holds and rhythmic stabilizations.

c. Endurance - this builds on what we see in Option A (some of the same exercises), but the resistance is a bit lower and it's done for higher reps or a longer time. The goal is less about strength and more about training the ability to hold the humeral head on the glenoid fossa for a lengthier period of time. I'd call it more important for a sport like swimming than for baseball or tennis athletes.

d. Irradiation - this can refer to just about any exercise, as your rotator cuff fires reflexively any time your arm moves. That said, certain exercises - bottoms-up kettlebell variations, for instance - are particularly useful for challenging this category of drills.

e. Patterning - these are just drills that take the humerus through its full range-of-motion. Of particular importance is end-range external rotation, which we train with drills like this:

2. I prefer near-daily exposures rather than exhaustive, less frequent programs.

If you look at our training programs, most of our pro guys are doing some kind of targeted training for the rotator cuff 5-6 days per week. Twice per week, we'll push more strength and irradiation work, and twice per week, we'll cover more timing drills. Just about every day, though, there will be some kind of patterning exercise so that we're reminding the cuff of what it's supposed to do.

This approach is a stark contrast to what you usually see in the baseball world, which is notorious for handing out the 2x/week arm care routines that take 45-60 minutes each. They're usually about 15 exercises for multiple sets, and leave an athlete hanging by the end of the session. I think this approach has more to do with the fact that it lines up with what's convenient for 2-3x/week physical therapy sessions than because it's truly optimal. I'm of the belief that you don't need (or want) to exhaust the cuff to get it to where it needs to be.

And, while we're at it, if the cuff is going to get abused on a daily basis with throwing, lifting, and activities of daily living, why not give it some more frequent exposure to build a little tissue resiliency?

3. Posterior deltoid shouldn't be lumped in with infraspinatus and teres minor.

Many times, the reason we have discomfort or the "wrong" feeling with drills is that athletes are paying close attention to the osteokinematics - gross movements of internal/external rotation, flexion/extension, adduction/abduction - of the joint in question, but not paying attention to the arthrokinematics of that same joint. In other words, the rolling, rocking, and gliding taking place needs to be controlled within a tight window to ensure ideal movement.

In shoulder external rotation variations, as we externally rotate the arm, the humeral head (ball) likes to glide forward on the glenoid fossa (socket). The glenohumeral ligaments (anterior shoulder capsule), rotator cuff, and biceps tendon are the only things that can hold it in the socket. In a throwing population, the capsule is usually a bit loose and the cuff is a bit weak, so the biceps tendon often has to pick up the slack - which is why some folks wind up feeling these in the front, thereby strengthening a bad pattern. There are also a bunch of nerves at the front of the shoulder that can get irritated.

Now, here's where things get a bit more complex. The infraspinatus and teres minor are both rotator cuff muscles that have attachments right on the humeral head, so they can control the arthrokinematics (posterior glide) during external rotation work. Conversely, the posterior deltoid (blue, in the image below) runs from the posterior aspect of the spine of the scapula to further down the arm on the deltoid tubercle. In other words, it completely bypasses control of the humeral head.


By Anatomography - en:Anatomography (setting page of this image), CC BY-SA 2.1 jp, https://commons.wikimedia.org/w/index.php?curid=22835985

With this in mind, the posterior deltoid actually creates a gliding forward of the humeral head as it externally rotates and horizontally abducts the arm. For this reason, you need to make sure the arm doesn't come back (horizontal abduction) as it externally rotates during your arm care drills. This video should clarify things, if you're a visual learner:

How Physical Maturity Impacts Pitching Mechanics and Muscular Recruitment

For today's post, I wanted to share with you an excerpt from my new resource, Sturdy Shoulder Solutions.

In addition to the injury implications of this presentation, I think we also have to consider how much it ties into the concept of accelerating development of young pitchers by getting them strong in the right places. Early strength and conditioning can help to facilitate the proper muscular recruitment patterns (i.e., using lats more than the rotator cuff and biceps) to generate higher levels of velocity.

Checks and Balances in the Shoulder of the Throwing Athlete

For today's guest post, I've collaborated with physical therapist Eric Schoenberg, one of my co-presenters at the Elite Baseball Mentorship. Enjoy! -EC

The #1 reason why a player or team does not succeed in baseball is injury. Today, there is a surplus of information, but at the same time a lack of basic understanding of how to keep a baseball player healthy. When in doubt, you can never go wrong by understanding and relying upon anatomy and quality human movement.

One key principle to understand in this regard is that there is a tremendous system of checks and balances working at the shoulder girdle to make sure that we control both the big movements (osteokinematics) and subtle joint movements (arthrokinematics) in a small window for health and performance. If we look to anatomy, we can appreciate a very important concept by looking at the attachment points for the deltoid, latissimus dorsi, and pectoralist major: your three biggest prime movers in the upper extremity. You'll notice that all three attach on the shaft of the humerus, not the humeral head. Take a look at their attachment sites on this anatomical chart, and then compare them to where the rotator cuff (supraspinatus, subscapularis, teres major, and teres minor) attach further up on the humeral head.

Source: http://howtorelief.com/humerus-anatomy-bony-landmarks-muscle-attachment/

You can appreciate that all these big muscles attach on the anterior (front) aspect of the humerus, which means that they have powerful pulls into internal rotation that have to be counteracted by fewer, smaller muscles that attach on the posterior (back) aspect of the shoulder.

Here are three specific implications of these anatomical observations that relate to how you manage your throwing athletes:

1. The Deltoid is strong/active enough!

The deltoid works in conjunction with the supraspinatus to form a “force couple.”

Source: www.MikeReinold.com

If the strength, recruitment, or timing of the deltoid is greater than the supraspinatus, then the result will be superior migration of the humeral head in the glenoid. This results in superior humeral head stress (chondral defect), undersurface rotator cuff tear, labral pathology, among other structural injuries to the glenohumeral joint.

Tip: Be sure that athletes feel rotator cuff strengthening exercises in the cuff and not the deltoid or biceps.

2. The lat is strong/active enough!

The lat (as it acts on the scapula) is opposed by the serratus anterior, lower trapezius, and upper trapezius to control scapular rotation. Increased relative stiffness of the lat results in excessive scapular depression and downward rotation at rest.

Additionally, if you have decreased activation or muscle performance of the scapular upward rotators and elevators with overhead motion, the outcome will be inferior migration of the glenoid on the humeral head.

This results in superior humeral head stress (chondral defect), undersurface rotator cuff tear, labral pathology, among other structural injuries to the glenohumeral joint.

Tip: Be sure that the athlete’s programs have a good balance of overhead reaching tasks done with proper mechanics and timing of the glenohumeral and scapulothoracic joints.

3. The pecs are strong/active enough!

Pectoralis major's impact on the anterior glenohumeral joint is opposed by the rotator cuff to prevent anterior humeral glide. Effectively, the pec and lats want to pull the ball forward on the socket as the arm goes through gross movements, and the rotator cuff works hard to prevent this gliding at the joint level.

Dominance of pec major over the rotator cuff muscles (namely subscapularis) will play a role in an athlete presenting with anterior humeral glide. We often hear the athlete report “tightness” in the front of the shoulder and their first option is to "stretch it."

This can lead to anterior shoulder pain and potential structural pathology including anterior joint laxity, biceps tendon pathology, and labral pathology – all common injuries in throwing athletes.

Tip: Rather than trying to decrease the “tightness” in the front of the shoulder by aggressively stretching—instead, focus on improving static alignment, proprioceptive awareness, and recruitment of the cuff. If you couple this with some self-massage work, this approach will yield far more favorable results.

In closing, the shoulder joint is happiest when alignment is optimal. Injury will occur if preferred alignment is altered. Examples of altered alignment at rest or with movement are the humeral head is riding too high in the socket, the socket is riding too low on the humeral head, or the humerus is gliding too far forward. The resultant stress to the active or passive restraints of the shoulder leads to injury and loss of playing time. Do yourself (and the players that you work with) a favor and master the basics to help improve success on the field.
