Description
No one can know how baseball players exert forces and moments on the grip handle from the batting motion. Because the bat is manipulated by double hands in batting, the upper extremities and the bat make a closed multiple-segment loop. The purpose of this study was to investigate three-dimensional kinetics of the upper extremities using an instrumented bat which measure forces and moments exerted on the bat by hands. Five varsity baseball players volunteered to participate in this study as subjects. The subjects performed T-batting, and they hit the ball as strong as they could. From the results obtained by this study, the role of the bottom side arm is making acceleration of the bat, and that of top side arm is doing modification of the bat motion.
