影响百米成绩因素的问题,目前在国内外争论得比较激烈。本文通过上海市各少体校少年短跑运动员进行的测量,并把所测得的数据经过整理和统计学处理,证明步长、腿长与百米成绩之间确实存在着密切的相关关系。同时,在本文中,根据推导出来的四个回归方程式,绘制了相应的回归直线图,最后排出了四张由步长、腿长推算百米成绩的对照表,可供教练员及运动员、体育教师在实践中参考。 The factors that have a bearing on the achievement of the 100-meter mark are now more heatedly debated at home and abroad. This article through the sparse athletes in various schools in Shanghai measurements, and the measured data after finishing and statistical processing to prove that the step length, leg length and the achievement of 100 meters there is indeed a close correlation between. At the same time, in this paper, according to the four regression equations derived, draw the corresponding regression line, and finally discharged four by the step, leg length meter calculate the results of the table for coaches and athletes, sports Teachers in practice reference.
