The purpose of this study was to analyze the effects of a progressive resistance training (RT) program on C-reactive protein (CRP), blood glucose (GLU), and lipid profile in older women with differing levels of RT experience. Sixty-five older women (68.9 ± 6.1 years, 67.1 ± 13.1 kg) were separated according to RT experience: an advanced group composed by 35 participants who previously carried out 24 weeks of RT and a novice group composed by 30 participants without previous experience in RT (n = 30). Both groups performed a RT program comprised of eight exercises targeting all the major muscles. Training was carried out 3 days/week for 8 weeks. Serum triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), GLU, and CRP concentrations were determined pre- and post- intervention after 12 h fasting. A significant group by time interaction (P < 0.05) for the TC (novice = -1.9% vs. advanced = 1.0%), and CRP (novice = -22.9% vs. advanced = -54.5%) was observed. A main effect of time (P < 0.05) was identified for the GLU (novice = -2.6% vs. advanced = -6.6%), TG (novice = -12.9% vs. advanced = -5.7%), HDL-C (novice = +6.7% vs. advanced = +2.6%), and LDL-C (novice = -34.0% vs. advanced = -25.4%). These results suggest that RT improves the metabolic profile of older women and that training for a longer period of time seems to produce more pronounced reductions mainly on CRP.
本研究旨在分析渐进性抗阻训练(RT)计划对不同RT经验水平老年女性的C反应蛋白(CRP)、血糖(GLU)和血脂谱的影响。65名老年女性(68.9±6.1岁,67.1±13.1千克)根据RT经验分组:高级组由35名先前进行过24周RT的参与者组成,新手组由30名无RT经验的参与者组成(n = 30)。两组均进行了一项由针对所有主要肌肉的八项练习组成的RT计划。训练每周进行3天,共8周。在禁食12小时后干预前后测定血清甘油三酯(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、GLU和CRP浓度。观察到TC(新手=-1.9% vs. 高级组=1.0%)和CRP(新手=-22.9% vs. 高级组=-54.5%)存在显著的组间时间交互作用(P<0.05)。对于GLU(新手=-2.6% vs. 高级组=-6.6%)、TG(新手=-12.9% vs. 高级组=-5.7%)、HDL-C(新手=+6.7% vs. 高级组=+2.6%)和LDL-C(新手=-34.0% vs. 高级组=-25.4%),确定了时间的主效应(P<0.05)。这些结果表明,RT可改善老年女性的代谢状况,且较长时间的训练似乎主要对CRP产生更显著的降低作用。
