The effect of aerobic exercise on primary motor cortical excitability is a relevant area of interest for both motor learning and motor rehabilitation. Transient excitability changes that may follow an exercise session are a necessary precursor to more lasting neuroplastic changes. While the number of studies is limited, research suggests that a session of aerobic exercise can create an ideal environment for the early induction of plasticity. Potential mechanisms include the upregulation of neurotransmitter activity, altered cerebral metabolism and cortisol levels, and increases in brain-derived neurotrophic factor. While there is considerable evidence that chronic physical activity positively impacts brain health and function, studies examining cortical excitability changes and motor performance after a single session of exercise are lacking. Further research is required to determine the clinical utility and feasibility of aerobic exercise.
有氧运动对初级运动皮层兴奋性的影响是运动学习和运动康复领域一个相关的研究热点。运动后可能出现的短暂兴奋性变化是更持久的神经可塑性变化的必要前提。虽然研究数量有限，但研究表明，一次有氧运动可以为早期诱导可塑性创造理想环境。潜在机制包括神经递质活性上调、脑代谢和皮质醇水平改变以及脑源性神经营养因子增加。虽然有大量证据表明长期体育活动对大脑健康和功能有积极影响，但缺乏研究单次运动后皮层兴奋性变化和运动表现的研究。需要进一步研究以确定有氧运动的临床实用性和可行性。
