Abstract:
BACKGROUND: Autonomic nervous system plays a critical role in mediating cardiovascular system to adapt the metabolic demands of the muscle activity, and is an important presenter and supporter of physical activity. OBJECTIVE: To systematically analyze the possible effects of exercise intensity, exercise modality, and exercise duration on autonomic nervous system regulation during and after exercise through reviewing the related literature on the autonomic nervous system and heart rate variability assessment of autonomic nervous system, so as to understand the mechanisms that meet the metabolic needs of physical activities. METHODS: PubMed and CNKI databases were searched using the keywords of “autonomic nerves system, heart rate variability, exercise intensity, exercise modality, exercise duration” in English and Chinese, respectively. The studies published from 1999 to 2018 were retrieved. RESULTS AND CONCLUSION: Cardiac autonomic neuromodulation is evaluated by heart rate variability index based on RR interval changes. Heart rate variability is a sensitive marker that reflects the co-regulation of cardiac function in sympathetic nerves and parasympathetic (vagal) nerves in the autonomic nervous system. In addition, the heart rate variability signals contain a large amount of regulatory information, including cardiovascular system, hormones and body fluids. Therefore, the mechanism of exercise-induced cardiac autonomic nervous system adaptation is still unclear. Exercise intensity may be the main factor affecting the regulation of cardiac autonomic nervous system during and after exercise. The training parameters such as exercise form and duration, as well as their interaction effects, may affect the adaptive process of cardiac autonomic nervous system.
