The specific aims of this study were to quantify the effects of 12 weeks of resistance training, as well as a single session of resistance exercise on lipids and lipoproteins in obese, postmenopausal women. 21 obese, postmenopausal women, not on hormone replacement therapy (age=65.9 ± 0.5 yr; BMI=32.7 ± 0.8 kg/m(2)), were randomly assigned to control (n=12) and exercise (n=9) groups matched for age and BMI. For 12 weeks, 3 days/week, the exercise group performed 10 whole body resistance exercises (3 sets at 8-RM). Fasting (10 h) blood samples were collected immediately prior to and 24 h after the first and last exercise and control session. Serum was assayed for concentrations of total cholesterol, triglycerides, LDL-C, HDL-C, HDL 2-C, HDL 3-C, non-HDL-C and TC:HDL and LDL:HDL ratios. The exercise group exhibited a significant (P<0.01) improvement in muscular strength, but no change in BMI, body mass or body composition post-training. Total cholesterol, LDL-C and non-HDL-C were significantly (P<0.05) lower in the exercise compared to the control group following the 12 weeks of resistance training. Whole body resistance training provides obese, postmenopausal women a non-pharmacological approach for the reduction of lipid and lipoprotein-cholesterol concentrations.
这项研究的具体目的是量化 12 周的抗阻训练以及单次抗阻运动对肥胖绝经后妇女的血脂和脂蛋白的影响。21 名肥胖绝经后妇女（未接受激素替代疗法，年龄=65.9±0.5 岁；BMI=32.7±0.8kg/m²），随机分为对照组（n=12）和运动组（n=9），两组在年龄和 BMI 上相匹配。在 12 周内，每周 3 天，运动组进行 10 项全身抗阻运动（3 组 8-RM）。空腹（10 小时）采血分别在第一次和最后一次运动和对照训练前后立即采集。血清用于检测总胆固醇、甘油三酯、LDL-C、HDL-C、HDL2-C、HDL3-C、非 HDL-C 和 TC:HDL 以及 LDL:HDL 比值的浓度。运动组肌肉力量显著提高（P<0.01），但训练后 BMI、体重或身体成分无变化。与对照组相比，12 周抗阻训练后，运动组总胆固醇、LDL-C 和非 HDL-C 显著降低（P<0.05）。全身抗阻训练为肥胖绝经后妇女提供了一种非药物降低血脂和脂蛋白胆固醇浓度的方法。
