Methods： The study collected 20 balls’ COR data after hitting two different sponge rubber with expansive solution for 5 days and asked the athletes to write the feeling list after hitting . The study adapted Two-Way ANOVA to analysis the data. Results：1. The balls’ COR of the two sponge rubbers with expansive solution were higher significantly than those without expansive solution. 2. The balls’ COR of the two sponge rubbers with expansive solution didn’t change significantly for 5 days. But the athletes felt that the balls’ COR of the two sponge rubbers with expansive solution decreased. 3. The racket’s vibration of the two sponge rubbers with expansive solution were higher than those without expansive solution. Conclusion： The balls’ COR of the two sponge rubbers with expansive solution indeed increased the balls’ COR and racket’s vibration. Key words：solution, coefficient of restitution, vibration amplitude, athletes’ feeling
