Biomechanical model of forehand stroke of tennis players

In recent years, tennis has become more and more popular. There is more and more research on tennis. The forehand stroke is the most important technique in many tennis techniques, and it is the main scoring means that all kinds of playing methods must have. With the continuous development of artificial intelligence technology, intelligent technical means are analyzed to improve tennis skills. In this paper, the tennis player’s forehand attack hitting image is analyzed in three dimensions. Through the three-dimensional video analysis method, the specific data information of each part of the body when hitting the ball is obtained, and a biomechanical model is constructed. The experimental results show that the shoulder-hip angle of high-level tennis players is 20.44°, while that of ordinary tennis players is 15.79°. From the statistical point of view, the significance test of the shoulder-hip angle between the two groups of players is P = 0.029, less than 0.05, with a statistical difference, indicating that high-level tennis players have a large shoulder-hip angle at the end of the backswing. A large shoulder-hip angle means that the body muscle tissues are more fully flexed and extended, and the stored elastic potential energy is greater. The results of the experiment can help people train tennis forehand skills more intelligently and pertinently.
