不同级别跳远运动员专项力量指标与专项成绩的相关研究

Research on Relations between the Specific Strength and Performance of Different Levels Long Jumpers

以我国不同级别男子跳远运动员48名为研究对象,运动员运动等级为健将级、一级、二级各16名,运用文献资料法、问卷调查法、因子分析法、逐步回归分析法、多元回归分析法、数学建模法建立预测专项成绩的专项力量指标方程。结果表明:我不同级别的运动员预测专项成绩的专项力量指标存在差异性,各预测模型均可作为预测该级别运动员的专项力量水平模型。

This paper has taken 48 different levels men Long Jump as study objects, consisting of master, primary, secondary, and used literature, questionnaire, factor analysis, stepwise regression analysis, multivariate Regression analysis, mathematical modeling methods to establish the special force projections Specific Performance Indicators equation. The results show that： Different levels of the athletes in Special Strength Index Score existing differences, the prediction model can predict the level of the athletes as a special strength level model.
