Abstract

The purpose of this study was to obtain basic data to be used for teaching ball handling in overhead passing in volleyball. The method used was simulation of a mass-elasticity-viscosity model consisting of arms, hands and ball. First, the acceleration of the ball was calculated during contact with the hands through means of VTR images. As a result of comparing this acceleration with that of the simulation of the model, it was found to be appropriate, and the coefficients of elasticity and viscosity were sufficient. The coefficients indicated that a skilled player changes hand elasticity depending on the height of set up. This is the reason that skilled players can control the ball with a greater degree of accuracy. On the other hand, unskilled players can not change hand elasticity as easily, which affects their control of the ball.
