| 内容記述 | The purpose of this study was to investigate the effects of shoulder range of motion, humeral retroversion, and corrected rotational angle on ball velocity in collegiate baseball pitchers. Twenty-one collegiate baseball pitchers participate in this study. Shoulder range of motion (internal rotation, external rotation, and total rotation) were measured in a supine position. Additionally, humeral retroversion angle was assessed using an ultrasound diagnostic device, and the corrected shoulder rotation angle was calculated. Body height, weight, lean body mass, and grip strength were also measured for all participants. Ball velocity was measured using a speed gun, and the maximum and average pitching velocities of five pitches were calculated. Pearson’s correlation coefficients were calculated to examine the relationship between the measured indicators and ball velocity. The results revealed that shoulder external rotation range of motion and corrected external rotation angle in dominant arm showed a significant positive correlation with both maximum and average ball velocity. In the multiple regression analysis, lean body mass was the only factor selected as a predictor of maximum ball velocity. The results of this study suggest that while shoulder external rotation range of motion is one of the factors that explain ball velocity, it is not as strong an influencing factor as lean body mass. |
