【摘要】 以北京体育大学的32名男子二级铁饼运动员为研究对象,运用体育测量与评价和统计学原理,经逐步回归计算分析,从被选入方程的8项指标中筛选出和男子二级铁饼运动员成绩相关最密切的变量指数,它们分别是体重X2、卧推X3、100m起跑X5,并得到了预测运动员成绩的回归方程:Y=32.7881+0.2726X2-2.0725X3+0.0774X5,旨在为教练员制定训练计划和选材时提供科学的依据。更多还原

【Abstract】 By taking the case of 32 athletes （level two） in Beijing Physical Education University, and through the application of principles in PE evaluation and assessment and by doing regressionanalysis, this thesis sifted out the most relevantcriteria to do with the achievements of Men discus athletes from the eight given criteria being included. They are weight X₂、floor press X₅, start（100 m）. We get the regression equation to predict achievement of Men discus athletes: y=32.788 1+0.272 6X₃-2.072 5X₃+0.077 4X₅. This equation can provide scientific data for coach to make training plan and picking athletes, the purpose of which is to provide scientific guide for trainers in the process of their making training plans.更多还原
