长时间的快速冲刺练习（即，团队运动）引起骨骼肌结构和功能的紊乱，其与收缩功能降低、炎症反应级联、感觉疼痛和延迟恢复到最佳身体表现相关。在这种情况下，从运动性疲劳的恢复传统上是从外周的观点来治疗的，肌肉生理学和其他外周因素的再生是恢复策略的目标。运动后恢复的研究叙述的方向不同，越来越强调在运动表现的中枢和外周因素调节运动强度之间的复杂相互作用。鉴于中枢神经系统（CNS）在运动过程中运动单位募集中的作用，它也可能在运动后恢复中发挥不可或缺的作用。事实上，这一假设是间接支持的一个明显的断开的时间过程中的生理和生化标志物的变化产生的运动和随后的恢复运动性能。同样，知觉恢复的改善，即使承受恢复的生理状态，也可能与前馈/反馈机制相互作用，影响后续的努力。考虑到恢复方法的研究兴趣，旨在加速恢复肌肉内的稳态，有限的重点从中枢神经系统的起源运动后恢复的贡献者是有点令人惊讶的。基于这种背景下，目前的审查旨在概述大脑的性能恢复后，剧烈运动的潜在贡献。
Prolonged intermittent-sprint exercise (i.e., team sports) induce disturbances in skeletal muscle structure and function that are associated with reduced contractile function, a cascade of inflammatory responses, perceptual soreness, and a delayed return to optimal physical performance. In this context, recovery from exercise-induced fatigue is traditionally treated from a peripheral viewpoint, with the regeneration of muscle physiology and other peripheral factors the target of recovery strategies. The direction of this research narrative on post-exercise recovery differs to the increasing emphasis on the complex interaction between both central and peripheral factors regulating exercise intensity during exercise performance. Given the role of the central nervous system (CNS) in motor-unit recruitment during exercise, it too may have an integral role in post-exercise recovery. Indeed, this hypothesis is indirectly supported by an apparent disconnect in time-course changes in physiological and biochemical markers resultant from exercise and the ensuing recovery of exercise performance. Equally, improvements in perceptual recovery, even withstanding the physiological state of recovery, may interact with both feed-forward/feed-back mechanisms to influence subsequent efforts. Considering the research interest afforded to recovery methodologies designed to hasten the return of homeostasis within the muscle, the limited focus on contributors to post-exercise recovery from CNS origins is somewhat surprising. Based on this context, the current review aims to outline the potential contributions of the brain to performance recovery after strenuous exercise.
