运动员的骨骼肌该如何适应运 动的反复刺激,很大程度上依赖着肌肉本身所固有的特性。具体地说,组成肌肉的肌纤维类型对于运动员更好地适应训练计划将产生巨大的影响。这就是为什么有的运动员比其他运动员在短跑中能跑得更快、肌肉更容易得到强化,而在长距离比赛中更容易坚持下来而无疲劳感的原因之一吧。为了给每名运动员设计出最佳的训练方案,作为教练员,了解运动员骨骼肌的复杂性是十分重要的。 一、肌纤维类型 (一)白肌纤维 人体有三种不同的肌纤维类型。收缩时间缓慢并具有强抗疲劳性的肌纤维称为白肌纤维(又称慢 The athlete’s skeletal muscle how to adapt to exercise repeated stimulation, largely depends on the inherent characteristics of the muscle itself. In particular, the types of muscle fibers that make up the muscle will have a huge impact on the athlete’s ability to better adapt to the training program. This is one of the reasons why some athletes can run faster in dash than other athletes, muscles tend to be more easily strengthened, and are more likely to stay fit and feel less tired in long-distance races. In order to design the best training program for each athlete, as a trainer, it is important to understand the complexity of athlete skeletal muscle. First, the type of muscle fibers (A) White muscle fibers There are three different types of human muscle fibers. Slow contraction and has strong anti-fatigue muscle fibers called white muscle fibers (also known as slow
