摘要
依据体育测量学和统计学基本原理对近3届(第30—第32届)奥运会我国女子摔跤项目的技战术进行测量与统计(原始数据共43场比赛419个指标),并从3个角度(容量、全面性、效果)进行定量分析。结果显示:(1)技战术容量统计方面,近3届奥运会技战术容量无显著性差异(t检验,P值均大于0.05),即3届技战术容量相当。(2)技战术全面性方面,从技战术类型缺失值来看,东京奥运会全面性最优(无缺失);从技战术使用比值看,里约奥运会(0.76)全面性排名第一。(3)技战术效果方面,东京奥运会(平均成功率为54.69%)和里约奥运会(平均成功率为54.12%)技战术效果均优于(t检验,P均值小于0.05)伦敦奥运会(平均成功率为33.02%),东京奥运会和里约奥运会技战术效果相当(P=0.94>0.05)。
This study employed principles from sports measurement and statistics to measure and analyze the technical and tactical aspects of China’s women’s wrestling events in the last three Olympic Games(30th to 32nd editions).A total of 43 matches with 419 indicators were used as raw data,and quantitative analysis was conducted from three perspectives:capacity,comprehensiveness,and effectiveness.The results revealed the following:(1)There was no significant difference in technical and tactical capacity among the three Olympic Games(t-test,all P-values>0.05),indicating consistent capacity across the editions.(2)In terms of comprehensiveness,the Tokyo Olympics exhibited the highest level of completeness with no missing values in technical and tactical types.Additionally,the Rio Olympics ranked first in comprehensiveness based on the ratio of technical and tactical usage(0.76).(3)Regarding effectiveness,both the Tokyo Olympics(average success rate of 54.69%)and the Rio Olympics(average success rate of 54.12%)demonstrated superior technical and tactical effectiveness compared to the London Olympics(average success rate of 33.02%)(t-test,all P-values<0.05).Furthermore,there was no significant difference in technical and tactical effectiveness between the Tokyo Olympics and the Rio Olympics(P=0.94>0.05).
