Effects of Extended Pitch Count On Shoulder Kinematics In Intercollegiate Baseball Pitchers.

Abstract
Several studies have been conducted investigating the biomechanics of pitching [1-9]. These previous studies all report high compressive and distractive forces for shoulder external rotation, elbow flexion with a maximum varus torque, shoulder adduction torque, and elbow extension. These characteristics may be exacerbated with increased pitch counts. The purpose of this study was to quantify changes in shoulder and elbow mechanics as a result of increased pitch count, by evaluating joint angles, accelerations, and velocities. Subjects each completed one testing session. Intercollegiate baseball pitchers pitched a simulated game, with 17 pitches per inning over the course of 9-innings. Shoulder and elbow kinematic data were evaluated for a fastball every tenth pitch of the simulated pitch count for each subject. Our overall hypothesis was that as the pitch count increased, abnormal throwing mechanics would result.
