Eleven healthy, untrained males (age = 44 +/- 1 yr; range = 40 to 55 yr) were studied to determine the effects of 16 wk of high-intensity resistive training on risk factors for coronary artery disease. Lipoprotein-lipid profiles, plasma glucose and insulin responses during an oral glucose tolerance test, and blood pressure at rest were determined before and after training. The training program resulted in a 13% increase in high-density lipoprotein-cholesterol (39 +/- 2 vs 44 +/- 3 mg.dl-1, P less than 0.05), a 43% increase in high-density lipoprotein-cholesterol (7 +/- 2 vs 10 +/- 2 mg.dl-1, P less than 0.05), a 5% reduction in low-density lipoprotein cholesterol (129 +/- 5 vs 122 +/- 5 mg.dl-1, P less than 0.05), and an 8% decrease in the total cholesterol/high-density lipoprotein-cholesterol ratio (5.1 +/- 0.3 vs 4.7 +/- 0.3, P less than 0.01), despite no changes in VO2max, body weight, or percent body fat. Glucose-stimulated plasma insulin concentrations during oral glucose tolerance testing were significantly lower, and supine diastolic blood pressure was reduced (P less than 0.05) as a result of the training program. No changes in any of these variables occurred in a sedentary control group. These findings indicate that resistive training can lower risk factors for coronary artery disease independent of changes in VO2max, body weight, or body composition.
对11名健康的未经训练的男性(年龄 = 44±1岁;范围 = 40至55岁)进行了研究,以确定16周高强度阻力训练对冠状动脉疾病危险因素的影响。在训练前后分别测定了脂蛋白-脂质谱、口服葡萄糖耐量试验期间的血浆葡萄糖和胰岛素反应以及静息血压。训练计划使高密度脂蛋白胆固醇增加了13%(从39±2mg·dl⁻¹增至44±3mg·dl⁻¹,P<0.05),高密度脂蛋白胆固醇增加了43%(从7±2mg·dl⁻¹增至10±2mg·dl⁻¹,P<0.05),低密度脂蛋白胆固醇降低了5%(从129±5mg·dl⁻¹降至122±5mg·dl⁻¹,P<0.05),总胆固醇/高密度脂蛋白胆固醇比值降低了8%(从5.1±0.3降至4,7±0.3,P<0.01),尽管最大摄氧量、体重或体脂百分比没有变化。口服葡萄糖耐量试验期间葡萄糖刺激的血浆胰岛素浓度显著降低,并且由于训练计划仰卧位舒张压降低(P<0.05)。久坐不动的对照组这些变量均未发生变化。这些发现表明,阻力训练可以降低冠状动脉疾病危险因素,而与最大摄氧量、体重或身体成分的变化无关。
