BIOMECHANICAL ANALYSIS AND EVALUATION OF THE POWER SERVE OF FEMALE TENNIS PLAYERS

The purpose of this study was to obtain and analyze the kinetic characteristics of the power serve in tennis and to jUdge whether or not the subjects' skills were reasonable. This in turn would provide a theoretical reference of the theory and training of the tennis power serve. Three-dimensional (3-D) videography was used to record the tennis service action of eight female tennis players. The analysis suggested that the theory of "whiplash movement" can be applied in the analysis of this performance. Quality and effectiveness of racket-swing action are decided directly by increased velocity and timing in successive segments from lower to upper. Some indexes were provided to evaluate the actions of the tennis power serve. Some suggestions were made to players for improvement in their performance
