Effect of Characteristics of Seamless Plastic Table Tennis on Ball Speed and Ball Spin

In order to have a deep understanding of the basic feature of seamless plastic table tennis ball and discover its effects on the ball speed and ball spin,using the methods of interview survey,experiment and statistic,etc,this paper compared the new seamless plastic table tennis ball with traditional celluloid table tennis ball,focused on the ball bounce,landing accuracy,ball speed and spin speed. Results: The hardness and bounce height of seamless plastic table tennis ball are slightly higher than those of celluloid table tennis ball,the bounce landing points' and flying arc's stability and accuracy of the seamless plastic ball are superior. Speed of seamless plastic table tennis ball is 2% less than that of celluloid table tennis ball and the spin speed of seamless plastic table tennis ball is 5% less. The spin of pulling the loop with seamless plastic table tennis ball and sticky glue is stronger than that of pulling with astringent glue. This study provides theoretical reference for developing techniques and tactics to deeply adapt to new ball.
