摘要

The purpose of this study was to determine the effect of different material of tennis courts for variation of speed and coefficient of restitution, and provide the movement and technique of tennis players. The tennis was served into hard court and clay court by tennis tower, and then captured immediately by VFC-300 high speed camera. Then the researcher adopted Kwon3D to analyze the data from films. Then we used statistical analysis with SPSS/Windows 12.0 to calculate the data. From the results, the variation of speed of clay court was greater than hard court (p＜.05), and the coefficient of restitution of hard court was greater than clay court (p＜.05). In conclusion, the players must adjust their hitting skills and tactics as different courts.
