In just the past few days, I've had two separate conversations with some really knowledgeable CP "dads" who also happen to have a ton of experience with coaching youth baseball players, particularly hitters.  In both conversations, a (paraphrased) line that stood out was "improving as a hitter in the teenage years is largely about learning to use the hips."

In contrast, have the same hitting conversation with just about any professional baseball player, and he'll tell you "I hit with my hands."

So who is right?  Do professional players not use their hips?  Or, do kids not use their hands?

Actually, both parties are right.  You don't get to professional baseball in the first place if you don't use your hips well when hitting.  And, you don't succeed (and stick around) in professional baseball unless you use your hands efficiently and have remarkable hand-eye coordination.  It's just multiple levels of natural selection that set the best apart - and they may sometimes forgot about the early stages of progress.

Need proof?  Watch a little league batting practice session, and then go to a big-league game to watch their batting practice.  The young players all pull the ball on every pitch, whereas the big-leaguers usually spray the ball all over the field, moving from the opposite field to the pull side.  They do this with their hands and wrists, all the while taking the hips for granted.

Think about this: how many more TFCC (wrist) injuries and hamate (hand) fractures do we see in professionals when compared to teenagers?  There are a lot more - because this area gets used a ton more.  Kids, on the other hand, get stress fractures if they misuse their hips.  It's no surprise, given the crazy rotational velocities and ranges of motion we see in hitters (outlined in my old articles, Oblique Strains and Rotational Power and Oblique Strains in Baseball: A 2011 Update).

What is a surprise, though, is that nobody has caught on to the ramifications of what this means for the youth baseball player who is learning to hit.

If a kid wanted to be a NASCAR driver, would we start him with a few 200mph laps at the Speedway amongst dozens of other drivers?  Of course not.

Why, then, do we have kids playing 180-200 games per year between school teams, AAU, fall ball, and even winter ball?  Where is the opportunity to learn how to hit in a controlled environment (closed loop), as opposed to trying to learn how to hit in live situations off of kids with no control (open loop).  Don't get me wrong; many programs do a tremendous job with instruction and really do build outstanding technical hitters - but as much as I hate to say it, the occupation of "hitting coach" seems to be a dying profession.  Why?

1. Schools are starting to put batting cages on campus for year-round hitting, and some kids don't appreciate that they need to learn to hit.

2. Some people see more money in AAU programs than individual instruction.  If a hitting lesson is personal training, running a team practice is semi-private training: more money in less time (and it's usually cheaper for the players).  This strategy can work if it's executed properly with sufficient coaching on-hand and the right demographic in mind; I have seen some AAU programs that are run with outstanding organization and excellent individual instruction at crucial parts of the year.

What is the right demographic?  I can't say for sure - but I can tell you that we need to be really careful in dealing with kids in the 11-17 year-old range.  They're learning to use their hips in an incredibly technically precise motion while their bodies are changing rapidly thanks to growth spurts and the fact that they spend 20 hours a day on their cans, thanks to sleeping, sitting at school desks, and playing around on Facebook and Instant Messenger.  We're giving more physically demanding challenges to less physically prepared (and, many times, less motivated) kids.

Kids need good hitting instruction early.  They also need targeted mobility work, foam rolling, and appropriate resistance training.

I moved to Boston in 2006, so this is the fourth season I've gone through with the L-S guys - and while I knew power numbers had increased, I didn't realize that they had virtually quadrupled.  I did, however, get my first hint of what was happening when we saw seven pitchers hit 80mph on the radar gun on the first day of tryouts this year.  This is a pretty big deal for any high school, and certainly one in Massachusetts that has to compete with nasty winter weather and the draw of lacrosse, track, tennis, golf, and volleyball during the spring season.  It's also significant because the competition in the area has improved quite a bit; L-S actually faces many of the players from other schools that we train - and they've gone 85-10 since the start of the 2007 season (when they won the state championship). Needless to say, it was pretty cool to be able to put some numbers with the trend we'd been observing.  And, it serves as a great reminder that - contrary to what a lot of "old school" coaches will try to tell you - a strength and conditioning program is absolutely essential for high school baseball players to not only perform at a higher level, but stay healthy in the process.  In this four-year period, LS baseball has had only one arm surgery, and it was in early 2008 on a player who had been misdiagnosed on ulnar nerve issues since middle school.  He's now playing Division 1 baseball.  The guys understand that arm care is about more than just some foo-foo rotator cuff exercises. This is what happens when the players in a program dedicate themselves to something and are consistent with it over the course of several years.

On Monday night, Josh Hamilton put on an amazing show with 28 homeruns in the first round of the MLB Homerun Derby. While he went on to lose to Justin Morneau in the finals of the contest, Hamilton did smash four 500+ ft. shots - and stole the hearts of a lot of New York fans. It's an incredible story; Hamilton has bounced back from eight trips to rehabilitation for drugs and alcohol to get to where he is today.

Geek that I am, though, I spent much of the time focusing on the incredible hip rotation and power these guys display on every swing. According to previous research, the rotational position of the lead leg changes a ton from foot off to ball contact. After hitting a maximal external rotation of 28° during the foot off “coiling” that takes place, those hips go through some violent internal rotation as the front leg gets stiff to serve as a “block” over which crazy rotational velocities are applied.

How crazy are we talking? How about 714°/s at the hips? This research on minor leaguers also showed that stride length averaged 85cm - or roughly 380% of hip width. So, you need some pretty crazy abduction and internal rotation range-of-motion (ROM) to stay healthy. And, of course, you need some awesome deceleration strength – and plenty of ROM in which to apply it – to finish like this.

Meanwhile, players are dealing with a maximum shoulder and arm segment rotational velocities of 937°/s and 1160°/s, respectively. All of this happens within a matter of 0.57 seconds. Yes, about a half a second.

These numbers in themselves are pretty astounding – and probably rivaled only by the crazy stuff that pitchers encounter on each throw. All these athletes face comparable demands, though, in the sense that these motions take a tremendous timing to sequence optimally. In particular, in both the hitting and pitching motions, the hip segment begins counterclockwise (forward) movement before the shoulder segment (which is still in the cocking/coiling phase). Check out this photo of Tim Hudson (more on this later):

Many of you have probably heard about a “new” injury in major league baseball – oblique strains – which have left a lot of people looking for answers. In fact, the USA Today published a great article on this exact topic earlier this season. Guys like Hudson, Chris Young, Manny Ramirez, Albert Pujols, Chipper Jones and Carlos Beltran (among others) have dealt with this painful injury in recent years. You know the best line in this entire article? With respect to Hudson:

“After the 2005 season, he stopped doing core work and hasn't had a problem. Could that be the solution?”

I happen to agree with the mindset that some core work actually contributes to the dysfunction – and the answer (to me, at least) rests with where the injury is occurring: “always on the opposite side of their throwing arm and often with the muscle detaching from the 11th rib.” If I’m a right-handed pitcher (or hitter) and my left hip is already going into counter-clockwise movement as my upper body is still cocking/coiling in clockwise motion – both with some crazy rotational velocities – it makes sense that the area that is stretched the most is going to be affected if I’m lacking in ROM at the hips or thoracic spine.

I touched on the need for hip rotation ROM, but the thoracic spine component ties right into the “core work” issue. Think about it this way: if I do thousands of crunches and/or sit-ups over the course of my career – and the attachment points of the rectus abdominus (“abs”) are on the rib cage and pelvis – won’t I just be pulling that rib cage down with chronic shortening of the rectus, thus reducing my thoracic spine ROM in the process?

Go take another look at the picture of Tim Hudson above. If he lacks thoracic spine ROM, he’s either going to jack his lower back into lumbar hyperextension and rotation as he tries to “lay back” during the late cocking phase, or he’s just going to strain an oblique. It’s going to be even worse if he has poor hip mobility and poor rotary stability – or the ability to resist rotation where you don’t want it.

Now, I’m going to take another bold statement – but first some quick background information:

1. Approximately 50-55% of pitching velocity comes from the lower extremity.

2. Upper extremity EMG activity during the baseball swing is nothing compared to what goes on in the lower body. In fact, Shaffer et al. commented, “The relatively low level of activity in the four scapulohumeral muscles tested indicated that emphasis should be placed on the trunk and hip muscles for a batter's strengthening program.”

So, the legs are really important; that 714°/s at the hips has to come from somewhere. And, more importantly, it’s my firm belief that it has to stay within a reasonable range of the shoulder and arm segment rotational velocities of 937°/s and 1160°/s (respectively). So, what happens when we give a professional baseball player a foo-foo training program that does little to build or even maintain lower-body strength and power? And, what happens when we have that player run miles at a time to “build up leg strength?” How many marathoners do you know who throw 95mph and need those kind of rotational velocities or ranges of motion? Apparently, bigger contracts equate to weaker, tighter legs…

Meanwhile, guys receive elaborate throwing programs to condition their arms – and they obviously never miss an upper-body day (also known as a “beach workout"). However, the lower-body is never brought up to snuff – and it lags off even more in-season when lifting frequency is lower and guys do all sorts of running to “flush their muscles.” The end result is that the difference between 714°/s (hips) and 937°/s and 1160°/s (shoulders and arms) gets bigger and bigger. Guys also lose lead-leg hip internal rotation over the course of the season if they aren’t diligent with their hip mobility work.

So, in my opinion, here’s what we need to do avoid these issues:

1. Optimize hip mobility – particularly with respect to hip internal rotation and extension. It is also extremely important to realize the effect that poor ankle mobility has on hip mobility; you need to have both, so don’t just stretch your hip muscles and then walk around in giant high-tops with big heel-lifts all day.

2. Improve thoracic spine range of motion into extension and rotation.

3. Get rid of the conventional “ab training/core work” and any yoga or stretching positions that involve lumbar rotation or hyperextension and instead focus exclusively on optimizing rotary stability and the ability to isometrically resist lumbar hyperextension.

4. Get guys strong in the lower body, not just the upper body.

5. Don’t overlook the importance of reactive work both in the lower and upper-body. I’ve read estimates that approximately 25-30% of velocity comes from elastic energy. So, sprint, jump, and throw the medicine balls.
