The purpose of this study was to compare difference of the shoulder range of motion, muscle strength and muscle endurance between twenty male baseball player and twenty male tennis player and establish prevention model on athlete coaching. The subjects were twenty to thirty years old baseball player and tennis player that have right dominant hand and have done repetitive overhead throwing 1years more. Shoulder external rotation and internal rotation range of motion measured to make shoulder 90° abduction and elbow 90° flexion in supine position. And for measuring shoulder posterior capsule tightness the range of motion, it was measured to make shoulder 90° flexion and elbow 90° flexion in sidelying position. The measurement of muscle strength and endurance was evaluated to use isokinetic equipment at 60°/sec and 180°/sec. Shoulder internal rotation range of motion between baseball player and tennis player was significant difference(p＜0.01) and shoulder posterior capsule tightness the range of motion was significant difference(p＜0.001). Shoulder internal rotation strength between baseball player and tennis player was significant difference(p＜0.05) in right and also appeared significant difference in left(p＜0.01). Shoulder internal rotation endurance between baseball player and tennis player was significant difference(p＜0.05) in right and also appeared significant difference in left(p＜0.05). In conclusion stretching training for preventing shoulder internal impingement that may occur from repetitive overhead throwing is important both group but it is more important in baseball player and the imbalance of shoulder muscle reduce function and make injury. So prevention training of these is important. Furthermore it is thought that study about comparison between multiple event is needed.
