Back in my What I Learned in 2010 feature, I made the following observation:

Babe Ruth hit a ton of homeruns in spite of being a seemingly out-of-shape fat guy. I've seen more than dozen pitchers throw well above 90 mph without even being able to vertical jump 23 inches.

What gives? Well, these athletes are just incredibly efficient – and powerful – in the transverse and frontal planes. Would being an elite sprinter make one a successful hitter or pitcher? Of course not, yet most strength and conditioning coaches train their rotational sport athletes as if they were trying to elevate them to elite status in a sagittal-plane dominant sport. They assume that general exercises like squats, deadlifts, and Olympic lifts will simply carry over once an athlete starts throwing or hitting.

And, to some degree, they do carry over because of the involved structures and systemic training effect, but I think that there's a way to tighten up the learning loop.

People think I'm crazy when I say that we don't Olympic lift our baseball players. We also don't do much vertical jumping. At the end of the day, jumping high doesn't really matter that much. Rotating fast and moving laterally quickly does, though, so we focus our power-oriented work on rotational medicine ball drills and lots of laterally-directed jumping/landing, and supplement it with lifting and sprinting.

I reiterated these thoughts a few weeks ago with my post, Why Baseball Players Shouldn't Olympic Lift.  This kicked off some heated debates, so I thought I'd contact Graeme Lehman for an interview on the topic.  As a brief background, back in 2010 - just a few months after I had the aforementioned article published - Graeme informed me that he was actually in the process of researching this very topic for his master's thesis.  Today, we're fortunate to have him here to discuss his findings and their practical applications.

EC: Thanks for agreeing to do this interview, Graeme. Can you start off by telling me a bit about both your baseball and educational backgrounds?

GL: First of all, thank you for asking me to do this interview; it is an honor to be a guest on your site, which I have used as an educational resource for years.

Baseball has always been my sport of choice despite growing up in Edmonton, Alberta during the 80s with the best hockey team ever assembled playing in my back yard (five Stanley Cups in seven years). I was fortunate enough to secure a scholarship to play baseball in North Dakota, but the school I attended didn’t have a kinesiology program, so I chose the major that I thought would afford me the best chance of getting a job, a degree in business administration. Ironically, and perhaps fatefully, my business degree got me a job as the manager of a small personal training studio. One day a trainer didn’t show up and I was thrown into the fire.

This first experience in a strength coach setting fueled a new found desire to educate myself about the world of exercise science. I read everything I could get my hands on including all of the articles that guys like you, Mike Robertson, Chad Waterbury, Mike Boyle wrote for T-Nation. I was hooked, and in 2006, I became a CSCS, and just one year later I was enrolled in a graduate school at the Memorial University of Newfoundland in Dr. David Behm’s Kinesiology program.

Since my collegiate days in ND, I have been both a baseball coach and strength coach for various individuals and teams including two years as the S&C for the UBC Thunderbirds. I have also continued playing in various men’s leagues in order to test out my own theories and keep chasing the dream hoping to become the next Jim Morris.

In case you’re trying to follow along with the various places I lived, they were:

1- Edmonton, Alberta (cold)
2- Jamestown, North Dakota (cold & windy)
3- St. John’s, Newfoundland (cold, windy and wet)
4- Vancouver, British Columbia (wet)

Living in these less than ideal climates has really made me excited about the work you do and the results you get in snowy Hudson, Massachusetts.

EC: How did you wind up deciding to pursue this research study, and what was the hypothesis that you were testing?

GL: My initial reasoning was quite simple: I wanted to help baseball players throw harder. As a strength coach, I thought that improving lower body power would be one of the best ways to achieve this goal. This led me to question: “what kind of lower body power can be improved in order to have a better chance of carrying over from the weight room to the baseball diamond?”

In the past, scores from traditional tests like vertical jump, broad jump and 60-yard dash times have not had any significant correlation to throwing velocity (Spaniol 1997). This made some sense because I have known some guys that I wouldn’t call “athletic” but could still throw gas. Mechanics obviously play a huge roll, but there is some research that stress’ the importance of lower body power in creating throwing velocity.

MacWilllams et al. (1998) showed that higher levels of force production by the back leg in the direction towards the plate led to higher wrist/ball velocity. While Matsuo et al. (2001) showed that what happens to a pitchers front knee between the time the front foot hits the ground and the time the ball is released is the key differentiator between “low” and “high” velocity throwing groups. Those that had the ability to extend their knee rather than going into further flexion threw harder.

So, it’s pretty easy to see that each leg is performing independent actions in a number of planes which don’t carry over to traditional bi-lateral sagittal. Thus, the principal of specificity was not taken into account and I know from your research, Eric, that you hate it when this principal is ignored.

It became obvious that we should be including tests which look at independent leg action, different planes of motion along with different kinds of strength (concentric, isometric, isometric).

EC: What kind of subjects did you have participating in the study, and what challenges did you face in dealing with them?

GL: My subjects were all male college level baseball players from two different teams. In total, I had 42 subjects who were approximately 19.8 years old and 183.3 cm tall and weighed 83.1 kg.

The biggest challenge was to create a list of tests which covered a wide spectrum of lower body power qualities to complement traditional running and jumping tests, which I also included. Each test also had to be easily reproduced by any strength or baseball coach in order to make this information user-friendly.

EC: Please describe your methods and the results you attained.

GL: We split up the athletes into left and right handed subjects and we measured throwing velocity was in two ways:

(1) Stationary throwing - similar to a pitcher throwing from the stretch.
(2) Shuffle approach - similar to a third basemen making a strong throw across the diamond.

This gave us four different groups. The throwing velocities from each group were correlated against the results of each lower body power test along with height and weight, looking for any significance. While there were was some correlation to body weight and med ball throws in one or two of the groups, only one test batted 1.000: the lateral to medial jump. This was the only test that was performed in the frontal plane.

Here is what this test looks likes. Stand on one leg then jump towards your midline in the frontal plane. Land with both feet together at the same time and take the measurement from the closest body part (lateral edge of the inside foot) to the starting line.

Since the lateral to medial jump score of the same side leg to the throwing arm (right leg for righties) went 4 for 4 in showing a positive correlation in each group, we made the conclusion that power is plane specific.

This was one of these “duh” moments because it makes obvious sense. If I can have more energy going towards my target, I have a better chance to transferring more energy up the kinetic chain to my throwing arm. If the rules didn’t stop me I would crow hop every time I pitched (like a Trevor Bauer warm-up) pitch trying to get as much as energy as I can going towards my target.

The pitching coach in me wants to warn against the young pitcher reading this and going out and trying jump towards the plate in order to boost their fastball. While it is important to initiate energy towards your target you need to be strong enough to capture and transfer that energy towards. If you aren’t strong enough on the front side you will exhibit what we in the business call an energy leak, just like the “low throwing velocity group from Matsuo’s study.

[Note from EC: for more reading on this front, check out my series, Increasing Pitching Velocity: What Stride Length Means and How to Improve It - Part 1, Part 2, and Part 3.]

EC: Okay, these are all well and good, but let’s talk practical applications. What can coaches take away from your research to immediately make their baseball strength and conditioning programs better?

GL: I think this helps us make smarter decisions in what we need to add/emphasize in our programs, and what we can subtract/deemphasize. Basically, we need to add more exercises that will improve frontal plane power and subtract some of the exercises that don’t. For example, hang cleans and drop jumps might help increase vertical jumping ability, but if goal is to throw 90mph these might not be the best use of our limited amount of time and energy.

The hard part about training the frontal plane is that your options are limited by traditional weight training. We need to think outside of the box like Bret Contreras did with his hip thrust in trying to improve running speed. Exercises that I would say to add or emphasis would be band resisted lateral jumps and lateral sled dragging since they are both performed in the frontal plane.

On the flip side, if we spend time working on creating more energy, we also have to think about how we can absorb it and ultimately transfer it to the baseball. This makes me think that single-leg training is very important, so we need to emphasize qualities like concentric strength for the back leg and eccentric strength for the lead leg.

EC: How about future research? What do we need to study next in order to build on these findings to continue to improve our understanding of long-term management of overhead throwing athletes, particularly pitchers?

GL: The next step would be to create a long-term study where a group of experienced baseball players train for 4-8 weeks. One group would include some frontal plane movements and the other wouldn’t. Test both pre and post throwing velocity and you’ve got another study. I wish I had the resources to do this, but I also don’t feel very ethical having some young baseball players not using these any frontal plane movements.

I think that these results also point to the fact that throwing a baseball is a full body movement. If we can get our pitchers throwing more like athletes and harness the power created by the lower body, we can eliminate some stress from the throwing arm keeping more baseball players in the game.

EC: Thank you very much for your great insights. Where can my readers find more from you?

GL: Thank you again for having me. I have a blog where I translate some of the geeky exercise science research related to baseball into Layman’s terms (cheesy use of my last name but it works). My goal there is to cover the gaps between the research lab, weight room and baseball field so that more players and coaches can benefit from all the information that is available.

You can also find me at Inside Performance, which is an awesome indoor baseball training facility in North Vancouver (possibly the rainiest place in the world) where I work as a S&C coach.

We're a few months into the college and professional baseball seasons. Not every pitcher's velocity is where it needs to be just yet, and that's no surprise. In today's post, I'll cover nine reasons why pitching velocity increases over the course of a season.

1. Increased external rotation

Over the course of a season, pitchers acquire slightly more external rotation at the shoulder (roughly five degrees, for most).  Since external rotation is correlated with pitching velocity, gaining this range of motion is helpful for adding a few ticks on the radar gun as compared to early in the season. However, this added external rotation comes with a price; more range of motion (especially if it's acquired too quickly) means that you be consistent with your arm care routines to make sure that you've got adequate motor control/strength in those positions. As I've often said, what makes you spectacular can often make you susceptible, too.

2. Optimization of mechanics

Many pitchers integrate subtle or dramatic changes to their mechanics in the off-season and early in-season periods, but these changes won't "stick" until they have some innings under their belt.  A few months in is often when those corrections start to settle in.

3. Transfer of strength to power

Some pitchers build a solid foundation of strength in the off-season, but take extra time to learn to display that force quickly (power).  In short, they're all the way toward the absolute strength end of the continuum, as described in this video:

If you want to dig in a bit deeper on this, this video on delayed transmutation is a good place to start.

4. More important game play

Some guys just don't get excited to pitch in games that don't mean much.  While that is an issue for another article, the point here is to realize that a greater external stimulus (more fans, playoff atmosphere, important games) equates to a greater desire to throw cheddar.  Soon, the MLB season will start, and high school and college post-seasons will be underway, so you'll start to see some of the big radar gun readings more frequently.

5. Warmer weather

Many pitchers struggle to throw hard in cold weather.  Some of the most dominant pitchers in the game have April fastball velocities that don't hold a candle to what they do during the rest of the year.

Warmer weather makes it easier to warm up, and many guys - especially the more muscular, stiff pitchers - need to lengthen the pre-game warm-up early in the season.  If you're a guy who typically doesn't see your best velocity numbers until you've got several innings under your belt, extend your pre-game warm-up, dress in layers, and don't pick up a ball until you're sweating.

6. New desire to prove oneself

For many pitchers, summer ball is a new beginning.  This might be in the form of a Cape Cod League temp contract, or a situation where a player is transitioning from a smaller high school that doesn't face good competition on to a program that plays a challenging summer schedule.  Again, that external stimulus can make a huge difference, as it often includes better catchers, better coaching, more fans, better mounds, and more scouts behind the plate. 

7. Mechanical tinkering

Piggybacking on the previous example, some pitchers may find their mechanics thanks to help from summer coaches.  So, a change in coaching perspective can often bring out the best in guys.

8. Freedom to do one's own thing.

I know of quite a few cllege pitchers who've thrived in the summer time simply because their pitching coaches haven't been in the way.  Usually, this means they can go back to long tossing rather than being restricted to 90-120 feet all season.  It's a great way to get arm speed back.

9. Different pitch selection

The college season is about winning games, whereas summer ball is more about developing. There are quite a few college coaches who have guys throw 75% sliders in their outings to accomplish the former objective, whereas those same pitchers might go out and throw a lot of changeups in summer ball in order to develop the pitch. This is also often the case when you see MLB pitchers get absolutely shelled during spring training; they're usually working on something, or simply just trying to build up their pitch counts.

As an extension of this, summer ball is a chance for many guys to take a step back and really work on commanding their fastballs, so it's not uncommon to see a few more mph on the radar gun as this becomes more of a focus.

The pull-up is among the most sacred strength exercises in the history of weight training programs, ranking up there with squats, deadlifts, and bench and overhead presses.  This is one reason why I expect there to be burning Eric Cressey effigies in various strength and conditioning circles after they read the following sentence:

Some people would be wise to leave out pull-ups - at least temporarily.

Before you rip me a new one, please give me a few minutes to explain.

First off, I get it: pull-ups train the lats, and the lats are huge players in athletic function and the quest to get strong and gain muscle.  They're the biggest player in force transfer between the lower and upper body, and play key roles in core stability and breathing.  Specific to my baseball work, lat recruitment is higher during acceleration in professional pitchers than amateurs, showing that reliance on this big muscle helps generate increase pitching velocity, too.  I actually wrote an entire article back in 2006 about just how extensive the lat's role is, if you'd like to read more: Lats: Not Just for Pulldowns.

However, the "expansive" presence of the lats - running from the thoracolumbar fascia all the way up to the humerus - can make them a problem as much as they are a solution.  To that end, here are four reasons you may want take a break from pull-ups/chin-ups/pulldowns in your strength training program:

1. Heavy pull-ups can make the elbows very cranky - This is really the shortest and least complex of my arguments, so I'll get it out of the way early.  My personal best three-rep max chin-up is 321 pounds, at a body weight of about 188 pounds (so, the external load was 133 pounds).  My best raw three-rep max bench press is about 330 pounds, but what you might find surprising is that going heavy on the bench press is dramatically easier on my joints (particularly my elbows) than pull-ups/chin-ups are.  What gives?

First, when you bench press, you're doing a full-body movement.  There is leg drive and loads of core stability involved on top of the upper extremity activity that's taking place - so the stress is more easily distributed.  When you do a pull-up, your upper extremity is relatively isolated, so the stress is more concentrated.

Second, a pull-up is a traction exercise; it pulls the humeral head out of the socket, and essentially pulls the lower and upper arm apart at the top. When you lose bony congruence - one of the most important, yet overlooked components of joint stability - you have to pick up the slack with the active restraints (muscles/tendons) acting at the joint.  Low-level traction can be tremendously helpful in situations like external impingement at the shoulder, or intervertebral disc issues.  However, under extreme load, it can be pretty darn stressful to the soft tissue structures around the joint.  Conversely, a bench press is an approximation exercise, so you can actually draw some stability from the joint alignment itself to take some of the stress off the soft tissue structures.

I remember Jason Ferruggia writing recently about how heavy chin-ups/pull-ups can really beat up on older lifters - and it's safe to say that the reason isn't so much tissue degeneration, but simply that it took time for them to build appreciable enough strength to get to the point where the overall stress was too much.

2. The lats overpower the lower traps - The overwhelming majority of the baseball athletes I see (and most extension/rotation sport athletes, in general) live in lordotic postures.  The lat is a strong extensor of the spine - but it also attaches to the rib cage and scapula on the way to the upper extremity.  The end result is that many lordotic athletes wind up with a very "gross" extension pattern.

The rib cage flairs up, and the lower traps do little to pull the shoulder blades back and down on the rib cage - because the lats have already gotten an athlete to the position he/she wants to be in via lumbar extension.  You can see from the picture below that the line of pull of the two muscles is actually very comparable - but given cross sectional area and length, the lat will always have the upper hand, especially if it's constantly being prioritized in a strength training program due to exercise selection and faulty lifting technique.

Effectively, we need to learn to move our scapulae on our rib cage, as opposed to just moving our entire spine into extension.  Interestingly, you'll find a lot of flexion-bias in the Postural Restoration Institute (PRI) and Dynamic Neuromuscular Stabilization (DNS) schools of thought because they clearly appreciate that getting folks out of "gross extension" is a way to get/keep people healthy.  Having ultra short/stiff lats can cause issues ranging from extension-based back pain (e.g., spondylolysis) to shoulder pain (e.g., external or internal impingement).  As I've written previously, too, this global dysfunction may also be the reason we're seeing more femoroacetabular impingement in athletes.

As another interesting aside, I see a lot of throwers with low right shoulders and incredibly short/stiff lats on that side.

This is secondary to faulty rib positioning and the scapular anterior tilt that ensues (as per the PRI school of thought), but one additional thing we've found (thanks to great feedback from physical therapist Eric Schoenberg) is that overhead shrugging variations on the low shoulder have helped these throwers to not only feel better, but minimize these asymmetries.  Effectively, creating a bit more stiffness in the upper trapezius helps it to counterbalance the aggressive downward pull of the lat on the scapula.

These folks sit in scapular depression, and for that reason, we'll often leave out any exercises (e.g., deadlifts, dumbbell lunges) that involve holding heavy weights in the hand until scapular positioning is better controlled.

3. The humeral attachment portion of the lat is part of a significant zone of convergence at the posterior shoulder - The back of your shoulder is another one of those claustrophobic areas in your body.  You've got tendons for the lat, teres major, teres minor, infraspinatus, long head of the triceps, and posterior deltoid all coming together in a very small area, creating friction over each other as their individual forces come together (regions like this are called "Zones of Convergence" by myofascial researcher Luigi Stecco.

The latissimus dorsi is, without a doubt, the largest and strongest of all the involved structures.  It also has the longest tendon, which makes it the biggest candidate for nasty tissue quality in the region.  The problem is that muscles/tendons don't deform evenly; rather, they move a lot where the tissue quality is good, and very little where it is dense.  So, when you're super dense in the posterior shoulder and try to go do pull-ups, as I noted earlier, the entire shoulder girdle wants to move (humeral extension and internal rotation, and scapular depression) together, as opposed to a nice synergy of the humerus with the scapula on the rib cage.  When some is stiff in the posterior shoulder and wants to use the lat for everything, a seated cable row looks like this.  Notice how the elbow winds up behind the body, and the scapula anterior tilts - and also how old the video is; I look like I am 12 years old and weigh 120 lbs.

Rowing like this over time will eventually irritate the anterior shoulder.  However, watch this standing one-arm cable row where the humeral head (ball) maintains a good alignment with the glenoid fossa (socket) as the shoulder blade moves on the rib cage.  The humerus doesn't extend unless the scapula moves with it.

4. Overactive lats can decrease the subacromial space - The lat extends, adducts, and internally rotates the humerus.  In order to get overhead the right way, we need flexion, abduction, and external rotation of the humerus.  So, you can see that it's a direct antagonist to healthy, overhead movement.  If you think about your biggest players for pain-free overhead movement, two of them have to be the posterior rotator cuff and lower trapezius.  The lat overpowers both of them in a "gross" extension pattern.

Here's a test: position yourself supine, bend the knees, flatten the lower back, and then let your arms hang freely overhead.  Then, have someone take a picture looking down at the top of your head.  A "pass" would be full shoulder flexion with no arching of the back, and no shoulder pain along the way.  A fail would be pain, or something that looks like this:

If your photo looks like this, you better hope that you have outstanding posterior rotator cuff and lower trapezius function (adequate stiffness) to overpower some very short lats if you intend to train overhead pain-free (especially with overhead pressing).  Otherwise, your shoulder flexion will really just be lumbar extension and forward head posture substitutions (this one has a nice left rib flair, too).

In other words, you need adequate anterior core stability and good recruitment of the deep neck flexors, too, but those are blogs for another day.

Closing Thoughts

This post has gone on far too long, and to be honest, I've probably just used the last 1300+ words to piss a lot of you off.  You'll be happy to know, however, that we still use a ton of pull-ups/chin-ups in our strength training programs at Cressey Performance.  In fact, they're a mainstay.  Here are some modifying factors, however:

1. The risk:reward ratio gets a little out of whack once you get very strong with pull-ups.  You'd be better off adding sets and reps, as opposed to adding load - and you may want to push the heavy stuff less frequently than you would with compound exercises.

2. Get regular manual therapy at the posterior shoulder and entire elbow to stay on top of tissue quality. At the very least, make sure you're foam rolling a ton and using The Stick:

3. Strengthen the anterior core and deep neck flexors so that you don't substitute lumbar hyperextension and forward head posture, respectively, for shoulder flexion.

4. Strengthen the lower traps so that the lats can't overpower them.  I like wall slides at 135 degrees abduction, as it allows one to work in the direct line of pull of the lower traps.  Make sure to cue "glutes tight, core braced" so that folks can't substitute lumbar extension ("gross extension") for movement of the scapulae on the rib cage.  Make sure there is no forward head posture, too.

Prone 1-arm trap raises off the table are also a popular one.  Just make sure you continue to cue "glutes tight, core braced, and no forward head posture."

4. Maintain adequate length in the lats. In warm-ups, I like the bench t-spine mobilizations and side-lying internal external rotation as a means of getting some shoulder flexion.

In terms of static stretching, a lat stretch in the power rack is great.

If this gives you an impingement feeling, regress it a bit, stabilize the scapulae with the opposite hand, and gently dip into a wall lat stretch with stabilization.

Many folks will also benefit from this classic overhead stretch in order to reduce stiffness in the long head of the triceps, a synergist to the lats in humeral extension.

5. Make sure you're including plenty of horizontal pulling (rowing) strength exercises as well - and executing them with the correct form.  This means moving humerus and scapula together on rib cage, not just yanking the humerus into extension on a fixed scapula.

6. If you have terrible shoulder flexion and can't get overhead without substituting forward head posture and lumbar hyperextension, spend some time addressing the underlying issues before you start cranking on pull-ups.  We actually don't do any pull-ups/chin-ups with some of our professional baseball players for 4-8 weeks following the season, as we need to spend time building rotator cuff, lower trap, and anterior core strength. I like to use the back-to-wall shoulder flexion exercise as a "pass/fail test." If you can get the thumbs to the wall without losing the flat-back posture on the wall or bending your elbows, then you can probably start going to pull-ups.

7. Above all else, listen to your body, and hold back if pull-ups/chin-ups hurt.

I'd love to hear your thoughts on this post and your experiences with heavy and/or high-volume pull-ups/chin-ups in the comments section below.

Pitchers need strength to have mobility.

So, without even getting to my list, you can say that mechanical proficiency is the #1 factor that influences whether a long stride will improve your pitching velocity.  Dial in what needs to be dialed in, and it could work wonders for you - if your body is prepared.

To that end, in part 2 of this series, I'll outline five physical factors that will help you improve your stride length and increase pitching velocity.
