女排队员防守起球率与运动素质多元回归分析

Multiple Linear Regression Analysis between Defensive Play Ball Rate of Women's Volleyball Players and Their Fitness

在女排运动中,运动员的运动素质指标与防守起球率有着直接的关系。人们通常认为800米跑、立定三级跳远、仰卧起坐、3米折返跑、思维灵敏性、运动知觉和适竞感7项指标与防守起球率有一定的相关性。但它们与防守起球率的回归结果表明:800米跑与防守起球率相关关系不显著;而思维灵敏性、仰卧起坐、3米折返跑、适竞感4项对防守起球率的影响显著,立定三级跳远、运动知觉却相对较弱。

Indexes of women＇s volleyball players＇ fitness directly relate to defensive play ball rate. It is commonly believed that seven indexes, i. e. , 800-meter run, standing triple jump, sit-ups, 3-meter turn back, cognitive sensitivity, motion perception and adaptability of competition, are correlated to defensive play ball rate. The multiple linear regression analysis indicates that 800-meter run is not correlated to defensive play ball rate while cognitive sensitivity, sit-ups, 3-meter turn back and adaptability of competition are correlate weakly with defensive significantly correlated and standing play ball rate. triple jump and motion perception
