| 内容記述 | [Abstract]The purpose of this study was to clarify the characteristics of right-handed pitchers with a quick pickoff movement to first base. Ten collegiate baseball players participated in the study. The three dimensional coordinates of reflective markers attached to the subjects and to the ball during a quick pickoff movement to first base were obtained using a motion capture system with 22 cameras（250 Hz）. A significant positive correlation was found between the pickoff time and the motion time from the beginning of the pickoff movement to ball release（r = 0.894）. However, no significant correlation was found between the pickoff time and the airborne time from ball release to reaching first base. These results indicate that it is important to shorten the motion time in order to achieve a quick pickoff. There was also a significant positive correlation between the stepping time from the beginning of pickoff movement to foot contact with the ground and the pickoff time（r = 0.731）, but not between the throwing time from the foot contact with the ground to ball release. That is, it is necessary to reduce the stepping time in order to shorten the motion time. Players with short stepping times tended to exhibit a high rotational acceleration of their torso（r = -0.926）. These results suggest that it is important to reach the maximum rotational velocity of the torso in the shortest time possible, and then quickly make foot contact with the ground in order to reduce the stepping time. | |||||||||||||
