Carriker, CR. Components of fatigue: mind and body. J Strength Cond Res 31(11): 3170-3176, 2017-Maximal intensity exercise requires significant energy demand. Subsequently, prolonged high-intensity effort eventually initiates volitional cessation of the event; often preceeded by a sensation of fatigue. Those examining the basis of fatigue tend to advocate either a peripheral or central model to explain such volitional failure. Practitioners and athletes who understand the tenants of fatigue can tailor their exercise regimens to target areas of potential physical or mental limitation. This review examines the rationale surrounding 2 separate models which postulate the origination of fatigue. Although the peripheral model suggests that fatigue occurs at the muscles, others have suggested a teloanticipatory cognitive component which plays a dominant role. Those familiar with both models may better integrate practice-based evidence into evidence-based practice. The highly individual nature of human performance further highlights the compulsion to comprehend the spectrum of fatigue, such that the identification of insufficiencies should mandate the development of a training purview for peak human performance.
卡里克尔，CR。疲劳的组成部分：身心。《力量与体能研究杂志》31(11): 3170 - 3176，2017年——最大强度运动需要大量能量。随后，长时间的高强度运动最终会引发该活动的自愿停止；通常在此之前会有一种疲劳感。那些研究疲劳基础的人倾向于倡导外周或中枢模型来解释这种自愿性衰竭。理解疲劳原理的从业者和运动员可以调整他们的训练方案，以针对潜在的身体或心理限制区域。本综述探讨了围绕两种分别假设疲劳起源的模型的基本原理。尽管外周模型认为疲劳发生在肌肉，但其他人提出了一种起主导作用的终末预期认知成分。熟悉这两种模型的人可能会更好地将基于实践的证据整合到循证实践中。人类表现的高度个体性进一步凸显了理解疲劳范围的必要性，这样，识别不足之处应该促使制定一个实现人类最佳表现的训练范围。
