短跑是以最快的速度,最短的时 间,较短的距离,以无氧供能来完成的周期性项目,包括60米、100米、200米、400米等项目,一般相对强度较大(在8～12米/秒之间)。 一、选材 短跑竞技水平的高低,很大程度上是由先天的遗传因素所决定的,可占到女子优秀短跑运动成材率的70％,后天是较难培养和改变的。 Dashing is a cyclical project that is completed with anaerobic energy supply at the fastest speed, shortest time and short distance, including 60 meters, 100 meters, 200 meters and 400 meters. Generally speaking, the relative intensity is relatively large In 8 ~ 12 m / s). First, the level of material sprint competition level, largely due to genetic factors determined by the innate, can account for the rate of women’s excellent sprint forming rate of 70%, the day after tomorrow is more difficult to train and change.
