Outline of Final Research Achievements

The purpose of this study was to make sure how to adjust the change of task requirements in ball throwing. Each participant threw two types of ball (same size, but different mass) in which two force sensors were equipped. They were also required to put two type of taping on the throwing fingers during throwing the ball at three ball velocities. The participants’ motion were recording by using a 10-camera high-speed motion capture system during the throwing. When throwing the ball with the slippery taping, they did not change grip force to the direction of the center of ball. Instead, they slightly decrease their grip force to the medial direction. As ball velocity and the mass of ball increased, angular velocities of the pelvis rotation and the thorax rotation increased. Elbow extension angular velocity increased as well. To cope with the required task, throwing was controlled with minimum adjustments.
