Abstract
The requirement of the golf club performance is to hit the ball with distance and accuracy. In addition, the "feeling" for golf swing is a very important performance, but it is very difficult to evaluate the "feeling" quantitatively. In this paper, we investigate the index value which is related to the "feeling" on the golf swing's motion. The golf swing motion is measured by using the motion analysis system at 500 Hz. During the golf swing we analyze swing characteristics. We focus on the club shaft deflection in swing motion and tester's swing speed. The relationship between the analytical result and the "feeling" is investigated. As a result, we showed the close relationship between the quantities of these features and the "feeling" performance.
