一个短跑或跨栏运动员,起跑反应时间的长短,对决定成绩有着重要的作用。这种反应不仅在不同人身上表现各异,就是同一名运动员也极不稳定。而且其差异多到几百毫秒。这是我们在一次集训中,对二十三名有经验的运动员,反复进行十至十五次起跑测验后,才认识到的。预测表明,运动员当时都不知道自身的反应时间及其变化。甚至连他们自己的教练员对此也无所了解。所谓起跑反应,指的是发令员发令(鸣枪,击物或规定的信号)使电动计时器启动,到运动员的脚蹬离起跑器的这一瞬间。我们对二十三名运动员总计进行了293次反应测验,总平均数为0.3秒,其中,他们每个人最短的反应时间平均数为
A dash or hurdler, the starting reaction time, the determination of the score has an important role. This reaction not only in different people’s performance, that is, the same athlete is also very unstable. And the difference is more than a few hundred milliseconds. This is what we learned after we conducted 23 training sessions with 23 experienced athletes and repeated 10 to 15 start-ups. Forecast shows that athletes did not know their own response time and its changes. Even their own coaches know nothing about it. The so-called starting reaction, referring to the starter command (shot, hit or the provisions of the signal) to start the electric timer, to the athlete’s foot off the starter from this moment. We conducted a total of 293 response tests on 23 athletes with a total average of 0.3 seconds, with the shortest response time for each of them averaging
