【摘要】：研究12周有氧运动抑或抗阻训练对单纯性肥胖患者自主神经功能影响的差异性.把55名肥胖患者随机分为有氧运动组(AE组,n=18)、抗阻训练组(RT组,n=18)和安静对照组(RC组,n=19).AE组进行有氧运动,RT组进行抗阻训练,时间均为12周(3次/周),RC组保持安静状态.分别于实验前后利用无创检测技术测定受试者的心率变异性(HRV)、血压变异性(BPV)和压力反射敏感性(BRS).实验后,AE组心率、血压、LF、LF/HF和LFSBP下降(P0.05或P0.01),HF和BRS升高(P0.01);RT组心率无显著性变化(P0.05),血压和LFSBP下降(P0.05或P0.01);RC组血液动力学及自主神经功能参数均无显著性变化(P0.05).因此,不同运动方式对单纯性肥胖患者自主神经功能均可产生积极影响,但机制不同,其中有氧运动降低交感调制,增加迷走张力,改善压力反射功能,而抗阻训练则减弱交感缩血管调制,对迷走调制以及压力反射功能无明显影响.
[Abstract]:To study the effects of 12-week aerobic exercise or anti-resistance training on autonomic nervous function in patients with simple obesity. 55 obese patients were randomly divided into three groups: aerobic exercise group (AE group), resistance training group (RT group) and quiet control group (RC group (n = 19).) AE group was given resistance training for 12 weeks (3 times a week). Heart rate variability (HRV), blood pressure variability (BPV) and baroreflex sensitivity (BRS) were measured before and after the experiment. There were no significant changes in heart rate (P0.05), decreased (P0.05 or P0.01) in HF and BRS (P0.01), but no significant changes in blood pressure and LFSBP (P0.05 or P0.01) in RC group (P0.05). Therefore, different exercise patterns have positive effects on autonomic nervous function in simple obese patients, but the mechanism is different, in which aerobic exercise reduces sympathetic modulation, increases vagus tension, and improves baroreflex function. Resistance training weakens sympathetic vasoconstriction modulation and has no obvious effect on vagal modulation and baroreflex function.
