| Research Abstract |
This study examined the relationship between baseball pitching velocity and various fitness factors. Positive correlations were found only with muscular strengths, such as squat strength and grip strength, while they were not high. There was no significant difference among the velocities when the range of torso rotation was restricted during the pitching delivery. On the other hand, a high correlation was observed between the pitching and the batted ball velocities. These results suggest that the coordinated effort of trunk rotation and the upper extremity exerts a great influence on the pitching speed. Furthermore, since there was no correlation with trunk rotation strength, the pitching speed depends more on a sequence of body movements than on exertion of power output ability. In short, the important factor to increase pitch velocity is the effective linkage of the trunk and the upper extremity.
