在接近踏板时,对跳远运动员的要求有三:(1)起跳脚尖紧靠板沿;(2)争取最大的竖直速度;(3)尽量减小水平速度的损失。 1、Lee等(1982)研究了为实现上述第一项要求的起跳方法,他们还试图建立模式化技术的控制起跳范围以确定跳远的标准步伐,使起跳时脚尖与板距离为零。运用转动摄影,他们拍摄了三位女运动员(个人纪录分别为5.78m,6.03m和6.54m)在接近过
There are three requirements for long jumpers as they approach the pedal: (1) take the toe close to the edge of the board; (2) maximize the vertical speed; and (3) minimize the horizontal speed loss. 1. Lee et al. (1982) studied the take-off method to achieve the above first requirement. They also attempted to establish the controlled take-off range of the modeled technique to determine the standard pace of the long jump so that the tiptoe-to-plate distance at take-off was zero. Using rotational photography, they photographed three female athletes (personal records were 5.78m, 6.03m and 6.54m respectively) approaching
