Neuromuscular fatigue occurs when an individual's capacity to produce force or power is impaired. Repeated sprint exercise requires an individual to physically exert themselves at near-maximal to maximal capacity for multiple short-duration bouts, is extremely taxing on the neuromuscular system, and consequently leads to the rapid development of neuromuscular fatigue. During repeated sprint exercise the development of neuromuscular fatigue is underlined by a combination of central and peripheral fatigue. However, there are a number of methodological considerations that complicate the quantification of the development of neuromuscular fatigue. The main goal of this review is to synthesize the results from recent investigations on the development of neuromuscular fatigue during repeated sprint exercise. Hence, we summarize the overall development of neuromuscular fatigue, explain how recovery time may alter the development of neuromuscular fatigue, outline the contributions of peripheral and central fatigue to neuromuscular fatigue, and provide some methodological considerations for quantifying neuromuscular fatigue during repeated sprint exercise.
当个体产生力量或功率的能力受损时，就会发生神经肌肉疲劳。重复冲刺运动要求个体以接近最大或最大能力进行多次短时间的运动，这对神经肌肉系统造成极大的负担，因此会导致神经肌肉疲劳的迅速发展。在重复冲刺运动中，神经肌肉疲劳的发展是由中枢和外周疲劳共同作用的结果。然而，有许多方法学上的考虑因素会使神经肌肉疲劳发展的量化变得复杂。本综述的主要目的是综合最近关于重复冲刺运动中神经肌肉疲劳发展的研究结果。因此，我们总结了神经肌肉疲劳的整体发展情况，解释了恢复时间如何改变神经肌肉疲劳的发展，概述了外周和中枢疲劳对神经肌肉疲劳的贡献，并提供了一些在重复冲刺运动中量化神经肌肉疲劳的方法学考虑因素。
