从力学观点研究跳高,我们可以确定,运动员最大的腾空高度包括三个高度:运动员置脚以支撑时总的质量重心的高度,运动员在起跳时总的质量重心升起的高度和运动员总的质量重心腾空的高度(这取决于运动员的垂直速度)。运动员跳过的高度是由最大的腾空高度和横竿以及和总的质量重心之间的距离差来决定的。(图1)诚然,如果我们能增大腾空高
From a mechanistic point of view, we can determine that the maximum height of an athlete consists of three heights: the height of the total mass center of gravity when the athlete puts her foot to support, the height at which the overall mass center of gravity rises during athlete take-off and the total mass of the athlete The height of the center of gravity vacates (depending on the athlete’s vertical speed). The height at which athletes skip is dictated by the difference in maximum emptying height and the distance between the crossbar and the total mass center of mass. (Figure 1) Admittedly, if we can increase the vacancy high
