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".
本章探讨了这样一种假说，即疲劳并非由任何一组常见因素单独引起，而是每个部位所承受的压力大小取决于导致疲劳的运动类型。通过比较各种因不同运动方案导致疲劳的研究结果，给出了支持这一观点的证据。然而，人类耐力随所执行任务的类型或强度变化的方式表明这是一个单一的过程。因此，也许整个神经肌肉系统调节得非常好，以至于一个部位与任务相关的任何额外损伤都能被其他部位相应的功能改善所补偿。我们认为大自然有很长时间来“把它做好”。
