Does It Help, Does It Hurt? A Look At Training For Baseball And Common Shoulder Injuries
By Ethan Bowlin
Is your training increasing or decreasing your risk of injury? Our goal is to function
at the highest level possible while reducing the risk of injury. Baseball is a sport that involves strength, speed, endurance,
flexibility, and mobility to name a few. What I have been seeing with baseball players from little league, early adolescence
into their adult lives is the widely accepted notion that to become a better athlete you have to train for form, not so much
function. What is the difference?
Form is what can be termed bodybuilding, building the body with focus on big muscles
or prime movers of the body. The chest, shoulders, abdominals, arms and quads, also known as mirror muscles, what we can see
in the mirror, are most commonly developed using machines and free weights. Bench press, crunches, biceps curls and knee extensions
are the exercises of choice. What is wrong with that, you may say? I thought that to be involved in athletics, I have to become
stronger and condition the body for that sport? Yes and no. Let me explain, let’s look at function.
Function is what is useful, how the body is utilized throughout different planes of
movement for a desired action. Baseball for example, involves throwing, hitting and running and must deal with forces that
cause rotation, forces that distract a joint during acceleration, and forces that must be decelerated, stabilized and transferred
to produce the desired action. So you ask, I thought that building my muscles stronger would accomplish that? When we focus
on form or bodybuilding only, you are creating an unbalanced environment.
Let’s take look at one of the most problematic issues regarding baseball players,
shoulder injuries. When an athlete throws a baseball, force is generated from the lower body and transferred through the core
into the upper body through the shoulder, elbow and wrist providing the “speed” of the baseball. However, the
force does not stop there. Once the ball is released, that force does not disappear, it must be decelerated back through the
wrist, elbow, shoulder, upper body, core and lower body. Simply stated, what you speed up, you must slow down.
The shoulder is the most mobile joint in the body, however, what we gain in mobility
we sacrifice stability. Picture the shoulder as a ball sitting on a plate, very mobile but not very stable. For the shoulder,
or any joint for that matter, must be stable before moving. Stability of the shoulder is heavily reliant on the rotator cuff
muscles. The rotator cuff muscles originate from the shoulder blade and its goal is to keep the ball centered on the plate
so the big muscles can produce the accelerating, decelerating and rotational forces while throwing. Muscles surrounding the
shoulder blade that provide stability for the shoulder joint include the lower trapezius, serratus anterior and rhomboid muscles.
All these muscles not only provide support for the shoulder but also are crucial in holding your posture.
Weakness in these muscles and focusing on strength training for the chest, arms and
abdominals will create an imbalance between the front and back of the shoulder girdle (upper body) possibly creating a rounded
upper back, forward head appearance (slouching). This imbalance places the upper back muscles in a lengthened position, which
will create greater stress on the rotator cuff during deceleration phase (follow through) of throwing and altered throwing
mechanics. Many times it can manifest as soreness and pain in the shoulder, down into the upper arm, elbow and forearm. So
how do I avoid this? Build your body like building a house. You wouldn’t start with the roof and windows before having
a solid foundation. Then don’t just jump into strength training, start with a strong stable foundation and proper alignment
before packing on the muscle!
First use a foam roller to loosen tight muscles and stretch the muscles around your
shoulder for optimal range of motion (For more information the foam roller, look at Relieve Pain with Foam). Stretching the
muscles in the front (chest, shoulders, and internal rotators) and strengthening the muscles in the back (lower trapezius,
rhomboids, and external rotators) will help to balance your shoulder girdle. Next, because we transfer force from the lower
body to the upper body while throwing and vice versa we target core stability and strength. The core involves more than just
your abdominals and low back; it includes the deep muscles along your spine down through your pelvis and hips. Most people
think of core exercises as movements such as crunches, twists and back extensions to name a few, however that is only one
part of it. Core exercises can be split into stabilizing and movement exercises. When we attempt to develop core strength
without core stability, we are forcing our bodies to rely on the prime movers, such as the chest, abdominals and shoulders
to do the stabilizing. We must be stable before we can move; otherwise energy is wasted while throwing, running and hitting,
all baseball movements. For a small range of exercises with a variety of uses from improving posture to sport specific exercises
