【摘要】：目的探讨有氧运动与人体心血管自主神经平衡状态的相关性。方法选择100例既往无有氧运动健身经历且符合研究要求的受试者100例为研究对象,将其中愿意参加健身锻炼的50例设为观察组,按照研究要求定期进行广场舞有氧运动锻炼;将无主观意愿参加健身锻炼的50例受试者设为对照组,保持原有生活习惯不变。8 w后分别检测并比较两组受试者心率变异性、心血管反射、平衡相关指标。结果 (1)心率变异性指标:观察组正常心动周期标准差(SDNN)、正常心动周期标准差均方根(SDNNindex)、相邻正常心动周期差值的均方根(r MMSD)、总频谱、低频成分、高频成分均明显高于对照组(P0.05);(2)心血管反射;观察组心血管反射正常率明显高于对照组(P0.05),临界率明显低于对照组(P0.05);(3)平衡指标:观察组睁眼、闭眼时摆动频率、摆动轨迹长、最大摆动角度、最大摆动速率均明显低于对照组(P0.05,0.01)。结论定期进行有氧运动锻炼有助于提高心血管反射,改善心率变异性,提高人体心血管自主神经平衡功能,是一项有益于人体健康的运动方式。
[Abstract]:Objective to investigate the relationship between aerobic exercise and cardiovascular autonomic nerve balance. Methods 100 subjects who had no aerobic exercise experience and met the requirements of the study were selected as the study subjects, 50 of them who were willing to take part in fitness exercise were set as observation group, and regular field dance aerobic exercise was carried out according to the requirements of the study. After 8 weeks, heart rate variability (HRV), cardiovascular reflex and balance were measured and compared between the two groups. Results (1) Heart rate variability (HRV) index: the normal cardiac cycle standard deviation (SDNN), normal cardiac cycle standard deviation mean square root (SDNNindex), adjacent to the normal cardiac cycle difference of the root mean square (r MMSD), total spectrum, low-frequency components in the observation group. The high frequency components were significantly higher than those in the control group (P0.05). (2) Cardiovascular reflex, the normal rate of cardiovascular reflex in the observation group was significantly higher than that in the control group (P0.05), the critical rate was significantly lower than that in the control group (P0.05). (3) balance index: the swing frequency, the length of the swing track, the maximum swing angle and the maximum swing velocity in the observation group were significantly lower than those in the control group when the eyes were open and closed (P 0.05, 0.01). Conclusion regular aerobic exercise is helpful to improve cardiovascular reflex, heart rate variability and balance function of cardiovascular autonomic nerve, which is beneficial to human health.
