The purpose of this study was to investigate the changes in pitching motion during a simulated baseball game. As the main results, the throwing arm shoulder joint abduction angle at stride foot contact decreased with increasing the number of pitches. The scapular elevation angle at stride foot contact decreased with increasing the number of pitches. The scapular abduction-adduction range of motion during stride foot contact to ball release decreased with increasing the number of pitches. The stride leg hip joint extension positive, negative and absolute work decreased with increasing the number of pitches.

这项研究的目的是调查模拟棒球比赛中投球运动的变化。作为主要结果，随着脚步的距离，投掷的手臂肩关节绑架角随着音高的数量增加而降低。脚步脚接触时的肩cap骨高度随着音高数量的增加而降低。步步足接触到球释放期间的肩cap骨外展吸收范围随着音高的增加而减少。随着音高数量的增加，步步腿髋关节伸展正，负和绝对工作减少。
