The aim of this study was to investigate elite female tennis player with forehand attack ball speed of different target. Five female tennis players were recruited as participants. Every participant has to hit 30 balls with her best strength, and the target partition 1.) No target 2.) Cross-court 3.) Down the line, and every single target have to got in 10 ball. A digital video camera, operating at 300 frames per second, were used to measure ball speed and accuracy of forehand attack in the respective situation. The ball speed was acquired by Kwon3D. All about ball speed data were tested by one way repeated ANOVA (α=.05). Results showed that cross-court and down the line of ball speed were significant greater than no target ball speed; and cross-court was also greater than down the line of ball speed, but there were no significant. This study find female tennis player hit the ball to cross-court more than down the line of ball speed, because when player use same power to hit the ball, hit to down the line has to use more spin, so the velocity is disperse more than the other one.
