一、准备活动与人体的惰性如果我们注意观察,在一场紧张的百米比赛中,虽然参加者都竭尽全力,一开始就企图以自己最快的频率奔跑,但都是在40—50米处才能达到最高速度。有人进行过研究,在一场篮球比赛中,队员们的投篮命中率在开始比赛后10分钟左右为最高。为什么会产生这些现象呢?因为任何物体都必需克服惰性才能前进,如我们乘坐汽车、火车时,由起动到高速行驶,需要克服惰性的时间。人不单纯是一个物体,而且是一个有生命的有机体,因此运
First, the inertia of the preparation activities and the human body If we pay attention to observation, in a tense 100-meter race, although the participants are making every effort to start running at their fastest frequency, they are all in the 40-50 meters. Can reach the maximum speed. Some people have conducted research. In a basketball game, the team’s shooting percentage is the highest in about 10 minutes after the start of the game. Why do these phenomena occur? Because any object must overcome inertia to advance. For instance, when we take a car or a train, from start to high speed, we need to overcome inertia. People are not simply an object, but they are a living organism.
