YO-YO间歇测试与足球运动员比赛跑动能力关联研究

目的:检验YO-YO测试与足球比赛跑动分析系统的信度与效度,探索YO-YO测试结果与比赛跑动能力的关系。方法:对24名国家男子足球队运动员进行YO-YO测试,对他们在16场国际比赛中的跑动能力进行研究,获取了每名运动员的YO-YO测试结果与比赛中的各种跑动参数。结果:YO-YO测试具有较高的重测信度(r=0.98)和较低的变异系数(8.7%),运动员的测试成绩由于位置不同表现出一定的差异性。SIMI跑动分析系统具有较好的稳定性,观察者内部与观察者之间的变异系数均小于3%,运动员比赛中的跑动能力也由于位置不同表现出一定的差异,且下半场跑动能力下降。YO-YO测试成绩与比赛跑动总距离、有氧高强度跑、无氧高强度跑、冲刺跑频数表现出较高的相关性(r=0.79,P<0.01;r=0.85,P<0.05;r=0.70,P<0.05;r=0.78,P<0.01),而与冲刺跑距离不存在显著相关(r=0.30,P>0.05)。结论:YO-YO测试与比赛跑动分析系统均具有较好的测试信度与效度;YO-YO测试能够反映与比赛密切相关的运动员体能,二者存在高度相关,可作为监测运动员体能变化的一项重要指标。

Study on the Relationship between YO-YO Test and Soccer Performance in Soccer Game

Objective:To test the reliability and validity of YO-YO test and soccer performance analysis system,and study on the relation between YO-YO test and soccer performance in soccer game.Methods:YO-YO test was done,meanwhile,the soccer performance in soccer games was analysis in 24 male national team players,and the result of YO-YO test and soccer performance were collected.Results:the test-retest CV and correlation for YO-YO test were 8.7% and 0.98,respectively.The result of YO-YO test variety according with the play position in match.The CV of inter-and intra-observer reliability for soccer performance analysis system were all below 3%,and performance in match was also according with the play position.YO-YO test has positive relationship to total distance,high-intensity running,very high-intensity running and sprinting frequency,(r=0.79,P<0.01;r=0.85,P<0.05:r=0.70,P<0.05;r=0.78,P<0.01),but have no relationship to sprinting distance(r=0.30,P>0.05).Conclusion:YO-YO test and soccer performance analysis system all have high reproducibility and sensitivity.Specifically,the YO-YO test was a validity measure of fitness performance in soccer,the test can be as a useful tool to check the player’s fitness.
