103 An analysis of the serve receive technique of forearm passing in volleyball

Abstract

Forearm passing is used in serve receive, passing free or down balls, setting, and floor defense. A player adjusts the direction of the ball and a distance to the target by changing the power to add to the ball and the inclination of the arm. A player must accelerate a ball when playing free ball, on the other hand, a player must absorb the ball's momentum when playing a hard driven spiked ball. We try to know how skilled player absorb the ball's momentum, how skilled player control the ball direction? Why unskilled player cannot control the ball well? This time, we use the wireless motion sensor (Logical product). It doesn't stress on subject, no cable needs.
