摘要
背景:比赛成绩分析在体育赛事中发挥着重要作用,这已在国际上达成共识。在乒乓球技战术分析领域,许多研究基于分阶段理论对运动员进行了分段评价。本研究提出了乒乓球精英运动员 "竞技技战术表现 "的概念。本研究的目的是开发一种基于熵的权重系统,并将其与三种综合评价方法相结合,旨在研究其在两种实际应用中进行评价的可行性:运动员之间的比较和不同时期的成绩波动。另一个目的是通过比较应用,探索不同综合评价方法的适用性:选取2019年6名男子乒乓球精英运动员共40场比赛,对其竞技技战术表现进行评价。以比赛中四个阶段的技术效果为相关指标,在熵权法的基础上,运用与理想解相似度排序优选法(TOPSIS)、排名总和比值法、奥斯定值法等三种综合评价方法。结果:(1) 六名乒乓球精英运动员的技术力量排名如下:该排名与2019年12月的国际排名表现出高度的一致性。值得注意的是,球员 C 的表现出现了明显的波动,而球员 E 则表现出了稳定上升的趋势。(2)肯德尔相关系数均超过 0.948,斯皮尔曼相关系数均超过 0.883,统计结果具有高度显著性(P 结论:这三种综合方法在评价运动员的综合表现方面都具有很强的适用性和很高的一致性。其中,TOPSIS 方法的效果更好。这种方法有助于更深入、更全面地体现乒乓球比赛分析,为运动员和教练员提供实际应用。
Evaluation of elite table tennis players' comprehensive technical and tactical performance.
Background: Game performance analysis has been playing a significant role in sports events which has reached an international consensus. In the field of technical and tactical analysis of table tennis, many studies conducted the segmented evaluation of players based on the phased-theory. The present study proposed the concepts of "competitive technical and tactical performance" of elite table tennis players. The purpose of this study was to develop an entropy-based weighting system integrated with three comprehensive evaluation methods, aiming to examine its feasibility for evaluation in two practical applications: inter-athlete comparison and performance fluctuations across time periods. Another purpose was to explore the applicability of different comprehensive evaluation methods through comparative application.
Methods: A total of 40 matches of six elite male table tennis players in 2019 were selected to evaluate their competitive technical and tactical performance. The technical effectiveness of four phases in a match as the relevant indexes, three comprehensive evaluation methods, including the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method, the Rank-sum ratio method and the Osculating value method were applied based on the Entropy weight method. Kendall's concordance coefficient and Spearman's correlation coefficient were employed to examine the consistency and correlation.
Results: (1) The technical strength ranking of the six elite table tennis players was as follows: Player A, Player B, Player C, Player F, Player E, and Player D. This ranking exhibited a high degree of consistency with the international rankings as of December 2019. Notably, Player C's performance showed significant fluctuations, whereas Player E demonstrated a steady and upward performance trend. (2) All Kendall's concordance coefficients exceeded 0.948, and all Spearman's correlation coefficients were above 0.883, with statistically highly significant results (p < 0.01).
Conclusions: All three comprehensive methods were shown to have strong applicability and high consistency in evaluating the comprehensive performance of athletes. The TOPSIS method performed more well. This approach facilitated a more in-depth and comprehensive representation of table tennis match analysis, providing practical applications for athletes and coaches.
