摘要
目的:对比不同运动方式对2型糖尿病(T2D)患者空腹和口服葡萄糖耐量试验(OGTT)后自主神经功能的影响,为制定针对特定人群的特异性运动处方提供理论依据。方法:T2D患者随机分为有氧运动组(AE组,n=16)、抗阻训练组(RT组,n=14)和安静对照组(RC组,n=14),以健康受试者为正常对照组(NC组,n=15)。AE组进行8周中等强度有氧运动,RT组进行8周渐进性抗阻训练,RC组和NC组保持日常生活习惯不变。实验前后分别测定安静空腹时和OGTT后的心率变异性(HRV)和压力反射敏感性(BRS)。结果:实验后,空腹状态下,AE组TP、nHF和BRS高于运动前(P<0.05),nLF和LF/HF低于运动前(P<0.05);OGTT后,各组TP、nLF和LF/HF均较空腹时显著性增加(P<0.05),nHF显著性下降(P<0.05),AE组和RT组nLF、LF/HF和nHF的变化幅度显著高于运动前水平(P<0.05),组间比较,RT组的变化幅度高于AE组(P<0.05)。结论:不同运动方式对T2D患者自主神经系统的影响存在差异,有氧运动可改善空腹时的自主神经功能,而两种运动方式均可改善葡萄糖负荷时的自主调制反应,但抗阻训练的效果优于有氧运动。
Objective：To compare the effects of aerobic exercise（ AE ）and resistance training（ RT ） on autonomic nervous function at fasting and after OGTT in type 2 diabetes patients. Methods：T2D were divided into AE group（n=16）,RT group（n=14）and resting control group（RC,n=14）, while health volunteers being normal control group（ NC,n=15 ）. AE group conducted 8 -week aerobic and RT group resistance training. Heart rate variability（ HRV）and baroreflex sensitivity （ BRS）were measured at rest and OGTT. Results：At fasting state after test,TP,nHF and BRS were higher while nLF and LF/HF lower in AE group than pre-test（P﹤0. 05）;after OGTT,TP,nLF and LF/HF increased,but nHF decreased in all groups compared with pre -test（ P ﹤0. 05 ）. Change extent of nLF,LF/HF and nHF in both AE and RT group were higher than those of pre-test,while extent of RT higher than AE group（P﹤0. 05）. Conclusion：Aerobic exercise improved autonomic function at fasting state,while both of the exercise modes could improve autonomic re-sponse to glucose load,but the effect of resistance training was better than aerobic exercise.
