概要

It is intended that the two new ball types, in addition to the existing ball type, be introduced and developed to improve the appeal and enjoyment of tennis at all levels for players and spectators alike. This paper shows the comparison between the predicted shock vibrations and the measured ones at the wrist joint when using the normal ball and the larger ball during the off-center impact and the center impact with the forehand stroke. The simulated results have fairly agreed with the experimental results. The waveforms of the shock vibrations at the wrist joint when using the larger ball is almost the same as those when using the normal ball independent of the string tensions. Since the drag force of larger ball should be larger than that of normal ball, the shock vibrations of a larger ball should be smaller.
