摘要
以灰色关联模型,Verhulst灰色微分模型和曲线回归模型为主要量化手段,对急行跳远诸因素的相互关联程度和发展趋势进行了研究。其作用在于:1)给出世界男子跳远运动员诸因素的发展趋势目标参数(身高、体重、最后4步助跑速度、腾起角度、腾空初速)。2)分析了当今、未来不同层次跳远运动员的差距产生的原因及其对策。
By means of the gray interrelated formula, Verhulst's gray differential dynamic model and curvilinear regression model, the study intended to deal with the interrelations and developing trend of the individual factors in men's dash broad jump. The purpose of this study is: 1 ) to determine the ideal parameters connected with the individual factors of future world men's broad jumper, such as height, weight, average velocity at the last four steps, take-off angle, and initial velocity at take-of f; 2) to analyze the reasons for causing different performance among the jurnpers at various levels, and also try to work out ways of solving these problems.
