摘 要: 目的:采用主成份分析法和卡方检验分别探讨影响中外优秀女子沙排运动员运动成绩的关键形态、关键技术和关键技术差距。结果:(1)年龄、身高、体重、防守成功率、拦网成功率、发球得分率、进攻成功率的贡献率分别为:0.145、0.065、0.065、0.284、0.284、0.079、0.079。(2)中国队的发球得分率和进攻成功率均高于美国队,防守成功率低于美国队,但三者均无显著差异(P>0.05)。中国队拦网成功率明显低于美国队(P<0.05)。结论:(1)影响中外优秀女子沙排运动员运动成绩的关键形态及关键技术是年龄、身高、体重、防守成功率、拦网成功率、发球得分率、进攻成功率,其中核心技术是防守成功率和拦网成功率。(2)中外优秀女子沙排运动员关键技术差距集中体现于拦网成功率。 Objective: the research is to investigate the factors of key morphology and key skill which affect sport performance of Chinese and foreign elite female beach volleyball players and to find the key skill gap between Chinese and world - class female beach volleyball players. Methods : Taking the examples of 24 pairs ( totally 48 players) of fe- male beach volleyball players of the 2012 London Olympic Games and by using the principal component analysis and Chi - square test, this paper discusses the factors of key morphology and key skill which affect sport performance of Chinese and foreign elite female beach volleyball players, the purpose of which is to find the key skill gap between Chinese and world - class female beach volleyball players. Results : ( 1 ) The contribution rate of age, height, body mass, defense success rate, blocking success rate, service scoring rate, attack success rate was 0. 145,0.065,0. 065,0. 284,0. 284, 0.079,0. 079, respectively. (2) The service scoring rate and the attack success rate of Chinese are higher than that of the USA, while the defense success rate of Chinese are lower than that of USA, yet no difference is found between these two teams( P 〉 0.05 ). The blocking success rate of Chinese is statistically lower than that of the USA. Conclusions : ( 1 ) The factors of key morphology and key skill which affect the sport performance of Chinese and foreign elite female beach volleyball players include age, height, body mass, defense success rate, blocking success rate, service scoring rate and attack success rate. (2) The key skill gap between Chinese and American players is mainly reflected in their blocking success rate.
