人类肌肉疲劳已经使用各种各样的运动模型，协议和评估方法进行了研究。基于疲劳的定义为“产生力或功率输出的最大能力的任何降低”，讨论了测量疲劳的不同方法。有人认为，可靠和有效的措施必须包括评估最大的自愿收缩力或功率，或电刺激产生的力。通过比较强直刺激和最大随意收缩力，可以揭示疲劳是否是中枢起源，或者是否涉及外周机制。适当使用抽搐内插提供了一个更敏感的测量中枢疲劳。间接的方法，如耐力时间和肌电图显示可变的反应，在运动过程中，没有密切的关系，疲劳。因此，这些方法在测量人体肌肉疲劳方面的价值有限。(C)1997年Elsevier Science B.V.
Human muscle fatigue has been studied using a wide variety of exercise models, protocols and assessment methods. Based on the definition of fatigue as 'any reduction in the maximal capacity to generate force or power output', the different methods to measure fatigue are discussed. It is argued that reliable and valid measures must include either assessment of maximal voluntary contraction force or power, or the force generated by electrical stimulation. By comparing tetanic stimulation and maximal voluntary contraction force one may reveal whether fatigue is of central origin, or whether peripheral mechanisms are involved. Adequate use of twitch interpolation provides an even more sensitive measure for central fatigue. Indirect methods as endurance times and electromyography show variable responses during exercise and no close relationship to fatigue. Hence these methods are of limited value in measurement of human muscle fatigue. (C) 1997 Elsevier Science B.V.
