基于三段评估法分析新材料球对竞技乒乓球的影响

Comparative Evaluation of Effect on the New Plastic Ball to The Competitive Ping-Pang Based On The Research Of Three-Segment Analysis

运用录像观察法、三段评估法等对2013、2014年世界杯和2013、2015年世锦赛单打前八名男、女优秀运动员在比赛中使用新材料球前、后的使用率、得分率进行统计与分析。并对乒乓球运动员使用新材料球后的主观感受进行了调查。研究结果表明:男、女优秀运动员在打法上新材料球与赛璐珞并没有明显差异,仍然以旋转、速度、力量相结合的进攻型打法为主;男、女运动员在使用新材料球后回合球并没有集中于相持段,总体显示出男、女运动员主要得分仍然较多的集中在"前三板";新材料球由于形状、重量以及空气阻力等影响,对来球速度、旋转及弹起高度有一定的影响。研究对未来如何适应新材料球的技战术训练和发展提供一定的理论依据和参考。

With the method of video observation and three - segment analysis, we statistically analyze the performance of male and female table tennis players in top eight in the 2013 ,2014World Cup and the2013 ,2015 World Championship of using rate and score rate. We mainly analyze the difference between new material and celluloid ball and investigate the plays subjective feeling after using new material balls. We find that there is not statistically significant difference before and after players using the plastic balls and those players still keep attacking style in spin, speed and strength. We also find that after using these new balls concentration of rally is not in male and female rally part and players main scores are still in the sampan. Because of new material balls’ shape,weight and air resistance,new material balls have influence on speed, spin and bounce. In view men-tioned above, the main contribution of our research is to provide some theoretical basis and references, which benefit the future development of training to adjust to application of the new material balls.
