本章探讨了这样的假设：疲劳并不是由任何常见因素引起的，而是每个部位承受的压力大小取决于导致疲劳的运动类型。支持这一观点的证据是通过比较各种研究的结果，其中疲劳是由不同的运动方案。然而，人类的耐力随着所执行任务的类型或强度而变化的方式表明了一个单一的过程。因此，也许神经肌肉系统作为一个整体已经调整得很好，以至于一个部位的任何与任务相关的额外损伤都可以通过其他部位相应的功能改善来补偿。我们认为，大自然有很长的时间来“把它做好”。
This chapter explores the hypothesis that fatigue is not caused uniquely by any common set of factors, but rather that the amount of stress placed on each site depends on the type of exercise from which fatigue develops. Evidence supporting this idea is presented by comparing results from various studies in which fatigue was caused by different exercise protocols. However, the way in which human endurance capacity changes with the type or intensity of the task performed suggest a unitary process. Thus, perhaps the neuromuscular system as a whole is so well adjusted that any task-related additional impairment at one site is compensated by corresponding functional improvements at others. We suggest that nature has had a long time in which to “get it right”.
