Study on Ball Serving Techniques of Young Tennis Players

摘要

To improve the ball serving techniques of young tennis players in Shandong province, all aspects of the service techniques of more than ten young tennis players are analyzed and studied from the perspective of kinematics through literature consultation, image parsing ways, etc. Results show that the young tennis players in Shandong province have a great difference from the world's excellent athletes and the national athletes in serve velocity, horizontal distances of ball-toss and ball-stroking, the hip angle at the lowest gravity center of serve, the average angular velocity of pedaling and stretching of knee joint in the "scratching back" action, the height in ball stroking, etc. However, the height of ball toss is reasonable. Also, the technique improvement measures with a clear purpose and the suggestions for the future trainings are proposed.
