训练中往往会出现这样的事,由于教练员们对短跑的特点认识不足,没有考虑到过多的耐力训练,会改变运动员肌肉的结构和类型,从而影响运动员速度的提高。运动员的速度,取决于体重、训练计划,特别是肌肉的类型和体积。人体的肌肉分为三型:慢红肌、快红肌和快白肌。慢红肌:不易疲劳,持续工作时间较长。日常走路这种最基本的活动由它完成。快红肌:持续工作时间短于慢红肌。快走和长跑
This often happens during training. Because trainers do not know enough about the characteristics of sprinting, they do not consider too much endurance training and change the structure and type of the athlete’s muscles, thereby affecting the athlete’s speed. The speed of an athlete depends on the weight, training plan, and especially the type and volume of muscle. The body’s muscles are divided into three types: slow red muscle, fast red muscle and fast white muscle. Slow red muscle: not easy to fatigue, longer working hours. The most basic activity of daily walking is done by it. Fast red muscle: continuous working time is shorter than the slow red muscle. Fast walking and long distance running
