Research and Application of Computer Three-dimensional Motion Capture System and Force Measuring Platform System in Different Types of Tennis Power Serve

This paper aims to explore the technical action characteristics of different types of power service of tennis players. The computer three-dimensional motion capture system and force measuring platform system are used to synchronously collect the kinematics and dynamics data of elite tennis players in the process of Flat Serve, Slice Serve and Topspin Serve. The conclusion is that the main differences between different types of tennis power serving techniques are that the body obtains different Ground Reaction Force in all directions, the rotation amplitude and angular velocity of shoulder joint, the direction composition of the maximum speed of racket head and the position of impacting point.
