Abstract

The purpose of this study was to compare the motion pattern of overpowering fastball pitchers. The throwing motion of eighteen male college pitchers were analysed using a motion capture system. This study focused on the movements of the pivot leg and the trunk during the preparatory phase. The overpowering fastball pitchers in the present study largely abducted the hip of the pivot leg and leaned the trunk toward the pivot leg during the preparatory phase. That these motions were seen during the preparatory phase would reveal that a key motion to get fast ball speed exist in the preparatory phase.
