The purpose of this study was to analyse the serving motion of the nineteen male college tennis players in simulated matches, and to seek for critical points for the improvement in the techniques by comparing with that of the world-class players reported by Fleisig et al. (2003) and Michikami (2014). The variables used in this study were the ball speed, racket speed, angles and angular velocities of the upper and lower limbs. Ball speed and racket speed for the male college players were significantly lower than that of the world-class players. The peak angular velocities of the right shoulder internal rotation and the left knee extension were lower in the male college players than those of the world-class players. For the improvement in the ball speed in serve, the critical points identified would be large angular velocities of the shoulder internal rotation and the knee extension.
