This study was performed to propose the direction of technical guide of slice service of elite tennis players. Speed change in upper joints was made by transferring quantity of motion to shoulders, elbow, wrists and rackets in the serve motion that ball makes an impact after being tossed. In order to change the path of return, correction should be made as the motion to keep the speed of the racket and the wrist to follow through motion because of the characteristics of slice serve. To increase angle speed of the racket in back swing zone, the magnitude that transferred to the curve of elbow joint angle should be increased. At the phase of impact, when speed of wrist joint and racket head out of upper joints increases, you can make a serve giving strong rotation. To help aforementioned results, height of projection and pre-speed of the ball should be increased by stretching elbow and knee joint angles as much as possible. When summarizing the aforementioned results and discourses, it is proposed that we need to reduce elapsed time of each zone to perform slice serve motion more efficiently, to improve the height of racket, speed of upper joints, speed of racket head and ball speed at impact, and to perform strong and fast supination of the wrist to make an effective and strong serve.
