本文研究之目的是论证短跑动态分离的方式。这一短跑活动方式的特点是运动员在跑的开始有一定的阻力,加快速度后,阻力明显减小。我们认为,用动态分离方式完成短跑活动可把运动员在水平方向的集中用力转向蹬地阶段的支撑,去掉制动结构的阻力之后,跑速会更快。研究方法。为了论证动态分离的方式,采用如下的手段和方法: 1、用8个∩A—3型动力描记台组成的连续不断的长6米能测张力的跑道(测定水平和垂直用力的相对误差不超过±5%); 2、为测定跑过规定地段的时间采用
The purpose of this study is to demonstrate the dynamic separation of sprinters. The characteristic of this sprint activity is that the athlete has some resistance at the beginning of the race. After accelerating, the resistance is obviously reduced. In our opinion, using the dynamic separation method to complete the sprint activity can shift the player’s concentration in the horizontal direction to the support in the step-by-step manner. After removing the resistance of the braking structure, the running speed will be faster. Research methods. In order to demonstrate the dynamic separation method, the following methods and methods are adopted: 1. A continuous 6-meter long runway capable of measuring tension composed of 8 ∩A-3 dynamic tracing units (the relative error between measured horizontal and vertical forces is not Over ± 5%); 2, for the determination of the passage of time required to adopt the lot
