Biomechanical Analysis of Forehand Shot in Tennis

Abstract

To explore the forehand stroke technique characteristics and kinematics rules. Use two sets of GC-PX10AC JVC high speed camera (50 frames/sec) field shooting, and use Signal TEC V2.0C 3-D software on the field shooting video analysis. Results show: (1) At backswing stage, the left shoulder angle is 46.3° and the left elbow angle is 143.8°. Arms are fully extended which is in line with the principle of modern tennis backswing; (2) At the moment of touching the ball, the angle of rotation of the shoulder-hip angle is 57.4° and the speed of racket head is 17.02m / s, reaching a maximum; (3) In the follow-up stage, the initial momentum of Kvitova passing to the ball is larger with the range and the distance. Most of the existing research for the right hand holding players, the study object for the left hand holding athletes, can provide a more comprehensive technical reference for tennis players.
