Abstract

Tennis and baseball are popular sports that have similar overhand motions, but result in two different final velocities. The two sports also have different risk of injuries. The study was conducted to compare the angular kinematics of both motions. One volunteer participated in the study. Subject's shoulder and elbow angular position and velocities throghout a first serve in tennis and a fastball pitch in baseball were recorded with the use of a camera-based motion analysis system. Both the Cardan sequence (XYZ) and Euler sequence (ZYZ) were used to analyze the motions within Visual 3D. A descriptive analysis was used to compare the two actions at the shoulder and elbow for angular position and angular velocity. Both sports showed similar overhead motions with regard to elbow and shoulder position. Overall, elbow angular velocity was larger in tennis than in the fastball pitch. Tennis also had a general higher angular velocity value in the shoulder. Angular velocity differences at the shoulder and elbow between a fastball pitch in baseball and first serve in tennis warrant further examination for injury risk assessment.
