400m障碍与相关身体素质多元回归方程的建立与分析

The Establishment and Analysis of Multi-dimensional Regression Equation for Military 400 m Steeplechase and the Correlation Physical Quality

以某院30名学员进行军事专项400 m障碍及各项身体素质的测试数据为研究基础,运用数理统计方法,通过建立400 m军事专项达标成绩与400 m、800 m、立定三级跳远、引体向上、卷身上、运动知觉六项身体素质之间的多元线性回归方程,并利用标准回归系数对各项身体素质在影响军事专项400 m障碍成绩中所处的主次关系加以确定和分析,以达到把握军事专项400 m障碍教学与训练重点的目的,为监督和控制军事体育教学与训练提供科学依据。

This research selected 30 students to take the tests for military 400 m steeplechase and physical quality.Through mathematical statistic,the authors established multi-dimensional regression equation between the performances of military 400m steeplechase and the six physical quality item of 400 m,800 m,standing triple jump,chin-up,on the volume body and the consciousness of motion to analyze and define the primary and secondary factor for the military 400m steeplechase so as to find the key point for the military 400m steeplechase and provides the scientific guide for supervising and controlling military sports teaching and the training.
