Arm Protection for the Throwing Athlete
by Cary Mendes, DPT
By this point of spring, baseball season is usually in full swing. This year, however, is different, and nobody knows when it will return. We hope to be back in time for summer leagues, American Legion and the showcase circuits this summer. In the meantime, it’s imperative that baseball players keep their arms in shape, especially with the drastic changes to throwing programs that have already occurred.
Remember that throwing is the epitome of a full kinetic chain movement. It involves every joint, from the big toe to the fingers. Our power comes from our legs and our core, so it's crucial to maintain lower extremity and abdominal strength. It requires great rotational strength through the obliques, as well as single leg stability through the glutes. Optimizing this chain will allow the arm to act like a whip and generate maximum velocity with minimal stress on the shoulder and elbow.
While the legs and the core are the foundation of throwing, we also need to make sure that the end of that whip is as strong as possible in order to protect it from breaking down. This is attained through a series of exercises that target the rotator cuff, scapular muscles, and wrist and elbow muscles, known as the Thrower’s Ten.
In the off-season, perform the following series of exercises: 2 sets x 10 reps, 2-3 times/week.
During the season, perform the following series of exercises: 1 set x 10 reps, 1-2 times/week.
