At the XVIII International Symposium on Biomechanics in Sports, Hong Kong 2000,we presented a paper on the validity of an impact model of ball and racket based on elasticity, viscosity and two bars elements. In that study, we focused on the vibration that appeared after impact. The present investigation analyzes the difference in impact phase between a string's tension and racket shaft strain during the attack period, when the ball hits the racket face. Comparing the results of the simulation model and the physical experiment we performed, it was considered that the phases of string's tension and shaft's strain at each impact points on the racket face were similar. Other mechanical valu■ for example contacting time of ball and racket and racket's vibration frequency, were similar to that of the experiment.
