摘要
目的:研究力量训练对老年人血管内皮功能和炎症因子的影响,探讨力量训练对增龄性血管内皮功能影响的机制。方法:11例老年男性[平均年龄(70.63±3.93)岁]进行12周的力量训练,使用多普勒超声显像技术测定受试者运动训练前后的血流介导的内皮依赖性血管舒张功能(FMD),同时检测血清肿瘤坏死因子-α(TNF-α)、白细胞介素6(IL-6)、超敏C反应蛋白(hs CRP)、脂联素(adiponectin)。结果:经过12周的力量训练后,老年人体脂率显著降低(P<0.05),血糖、血脂出现显著性下降,肌肉力量显著增加,同时FMD显著提高(P<0.05),而TNF-α、IL-6、hs CRP水平出现显著降低,adiponectin显著升高;FMD增加的程度与血清TNF-α、IL-6、hs CRP降低的程度,以及adiponectin升高的程度呈显著正相关。结论:12周的力量训练提高了老年人血管内皮功能,减低了炎症反应水平;力量训练提高老年人血管内皮功能与炎症水平下降有关,这可能是力量训练提高老年人心血管机能的机制之一。
