Abstract:In order to explore the materials and sports characteristics of new seamless table tennis more comprehensively, the speed and rotation of the ball have been tested. Through experiments and calculations, the traditional celluloid table tennis is taken as the control group to analyze the seamless table tennis. The test contents mainly include the bouncing, landing, rotation and speed characteristics of the table tennis ball. The results show that the seamless table tennis is superior to the celluloid table tennis in bouncing and hardness. The stability of the landing and the accuracy of the flight arc are better than that of celluloid table tennis. And the rotation of the seamless table tennis is about 5% less than that of celluloid table tennis. In addition, the speed of the ball decrease about 2%. As can be seen, the rotation effect of sticky glue ball tennis is better than astringent glue ball.
Key words:Seamless plastic table tennis; Speed; Bouncing height; Glue; Celluloid table tennis

目前,新型無缝塑料乒乓球已经完成了研制工作,并获得了国际乒联的检测与授权,将逐渐代替传统的赛璐珞乒乓球,成为国际乒乓球比赛中的主要用球。新型无缝塑料乒乓球的应用,使整体乒乓球运动产生了变革,在一定程度上改变了乒乓球运动员的技战术训练与发展。无论是物理特征还是击球效果,新型无缝塑料乒乓球与赛璐珞乒乓球都有明显的差异。除材料的不同外,变化最大的就是乒乓球的直径;新型无缝乒乓球直径的增大,直接对球体的硬度、弹性、速度、旋转等因素产生一定的影响。国际乒联主要将球体的反弹高度作为检测依据,尽管这样的检测方法能够判断出乒乓球的实际弹性,但实验所设置的初速度与实际训练及比赛过程中产生的初速度是不同的。……
