为了观察中长跑运动员长距离跑过程中步频和步幅的变化对身体机能反应的影响,8名运动员在跑台上分别采取主动加大步幅和主动减小步幅而增快步频的跑法,以相同的速度进行了两次5km跑,记录运动员在跑步过程中心率的变化并进行对比。结果显示,在相同速度5km跑的过程中,运动员采取主动减小步幅的跑法,其心率均值显著低于采取主动加大步幅的跑法。提示,长距离跑过程中,运动员采取主动减小步幅,或加大步频的跑法较为省力。
In order to observe the impact of changes in pace and stride on body function during the long-distance run, the 8 athletes take the initiative to increase the stride and reduce the stride on the treadmill to increase the stride frequency Run, with the same speed twice in 5km run, record the athletes in the running process of heart rate changes and compared. The results show that during the same speed of 5km, athletes take the initiative to reduce the pace of running, the mean heart rate was significantly lower than the initiative to increase the pace of the run. Tip, long distance run, the athletes to take the initiative to reduce the pace, or increase the pace of running more effort.
