ラケットの違いを考慮したテニス・ストローク動作解析

抄録

This paper examined the influence of the racket on tennis strokes motion. In the experiments, 13 male subjects hit the balls with four kinds of rackets, and the tennis stroke was recorded and digitized by twelve motion capture cameras. After that, using three-dimensional coordinate value of the body, the contribution of the segments to the velocity of racket head was calculated to derive the distinctive marker of the body in the tennis strokes. The position in the vertical direction of the marker was analyzed, and the changes of the stroke motion using each rackets were examined. As a result, an index of tennis stroke motion was derived.
