国内乒乓球最优混双组合的技战术量化研究——基于八轮次分析

Quantitative Research on Techniques andTactics of the Best Mixed Doubles in China--Based on Eight-Round

使用录像分析法观察国内乒乓球优秀混双组合王楚钦/孙颖莎在2021-2023年参与的25场国际比赛,运用多元回归和通径分析方法对王楚钦/孙颖莎八轮次技战术按重要程度进行排序并分析各轮次之间的交互效应.结果显示,王楚钦/孙颖莎八轮次技战术按重要程度由高到低依次排序为:轮次X_(4)>轮次X_(2)>轮次X_(6)>轮次X_(5)>轮次X_(8)>轮次X_(1)>轮次X_(3)>轮次X_(7).X_(2)和X_(6),X_(4)和X_(3),X_(4)和X_(7),X_(4)和X_(8),X_(5)和X_(3)之间存在明显交互效应.由此得出:比赛中发球轮次比接发球轮次更重要;各轮次之间相互影响,相辅相成;各轮次技战术的直接效应均大于间接总效应,X_(2)对其他轮次的积极影响最大,X_(7)对其他轮次的积极影响最小.

Video analysis was used to observe 25 key international matches in which Wang Chuqin/Sun Yingsha participated from 2021 to 2023.The Multiple regression and path analysis models were used to rank the importance of eight-round technical-tactical and analyze the interaction effects between each round.Result:the technical and tactical importance of the eight-round is ranked from high to low:rounds X_(4)>rounds X_(2)>rounds X_(6)>rounds X_(5)>rounds X_(8)>rounds X_(1)>rounds X_(3)>rounds X_(7).There are significant interaction effects between rounds X_(2)and X_(6),X_(4)and X_(3),X_(4)and X_(7),X_(4)and X_(8),and X_(5)and X_(3).Conclusions:service rounds are more important than receiving rounds in mixed doubles;each round influence and complements each other.The direct effect of each round is greater than the indirect total effect.Rounds X_(2)had the greatest positive effect on other rounds,and rounds X_(7)had the least positive effect on other rounds.
