基于动态三段法下孙颖莎与王曼昱的技战术特征分析——以2020年东京奥运会模拟赛为例

Analysis of the Technical and Tactical Characteristics of Sun Yingsha and Wang Manyu based on the Dynamic Three-segment Method——A Case Study of the Simulation Competition of the Tokyo 2020 Olympic Games

运用录像观察、动态三段指标统计、数理统计等研究方法,对国乒女队最年轻和打法最先进的两位队员—孙颖莎和王曼昱,在2020年东京奥运会模拟赛决赛中技战术特征进行研究。经过动态三段式分析和发球落点、接发球处理手段,相持段正、反手得失分情况的统计。结果发现:两者胜负的关键在于相持段;孙颖莎正手突出,单板质量高,接发球多以控制为主;王曼昱反手突出,相持能力较强,接发球多以拧拉为主。并提出加强在领先球局面下技术和心理方面的训练、相持段要主动寻求线路的变化、发抢段多变和接抢段积极上手的意识、强化身体训练等建议。

The methods of video observation,dynamic three-stage index statistics and mathematical statistics have been used in this paper to study the characteristics of techniques and tactics of Sun Yingsha and Wang Manyu,two of the youngest and most advanced players in the Chinese women's table tennis team,in the final of the simulation competition of Tokyo 2020 Olympic Games.Through the dynamic three-stage analysis,the change of the serve drop point in the whole match,the processing means of the return of the serve,the statistics of the points gained and lost by the forehand and backhand in the stalemate.The results show that the key to victory lies in the stalemate.Sun Yingsha's forehand is outstanding,the quality of the single board is high,and the return of serve is mainly controlled.Wang Manyu’s backhand is outstanding,and the stalemate ability is strong,with the serving and return of the serve mainly focusing on twisting and pulling.At the same time,some suggestions are put forward,such as strengthening the training of technique and psychology under the condition of leading the ball,actively seeking for the change of route in the stalemate section,the consciousness of changing the service and receiving section,and strengthening the physical training.
