| 内容記述 | The purpose of this study was to investigate the effect of string tension and impact location on the rebound coefficient between the ball and racket. Tennis balls were fired from a ball-throwing machine to a racket clamped in a vice. The racket and ball were filmed before and after impact with two synchronized high-speed video cameras at 250 Hz. Ball velocity before and after impact and impact location were obtained with a three-dimensional video analysis. No significant difference was found among the rebound coefficients of three rackets strung at 65 lbs, 55 lbs, and 45 lbs. As for the transverse direction the rebound coefficient was smaller as the distance from symmetrical center line of the racket face became greater. Rebound coefficients were larger in the area closer to the racket handle than the geometric center of the racket face. Remarkable decreases in rebound coefficients were recorded in the area close to the racket tip. | |||||
