Evidence suggests that physical activity has a beneficial effect of elevated high-density lipoprotein cholesterol (HDL-C) on reducing coronary artery risk. However, previous studies show contrasting results for this association between different types of exercise training (i.e., aerobic, resistance or combined aerobic and resistance training).The aim of this study was to determine which type of exercise training is more effective in increasing HDL-C levels. A total of 40 obese males, aged 18-29 years old, were randomized into four groups: an aerobic training group (n= 10), a resistance training group (n= 10), a combined exercise training group (n= 10), and a control group(n= 10). After 12-week of exercise program, anthropometrics, blood biochemical variables and physical fitness components were compared with the data obtained at the baseline. The multiple regression analysis was used to evaluate the association between different types of exercise training and changes in HDL-C while adjusting for potential confounders. The results showed that with the control group as the comparator, the effects of combined exercise training group (β= 4.17, P< 0.0001), aerobic training group (β= 3.65, P< 0.0001) and resistance training group (β= 2.10, P=0.0001) were positively associated with increase in HDL-C after adjusting for potential confounders. Our findings suggested that a short-term exercise program can play an important role in increasing the HDL-C level, either aerobic or resistance training alone increase significantly the HDL-C levels, but the improvements are greatest with combined aerobic and resistance training.
有证据表明，体育活动对提高高密度脂蛋白胆固醇（HDL-C）以降低冠状动脉风险具有有益作用。然而，先前的研究显示，不同类型的运动训练（即有氧运动、抗阻运动或有氧与抗阻联合训练）之间的这种关联结果相互矛盾。本研究的目的是确定哪种类型的运动训练在提高HDL-C水平方面更有效。共有40名年龄在18至29岁之间的肥胖男性被随机分为四组：有氧运动训练组（n = 10）、抗阻训练组（n = 10）、联合运动训练组（n = 10）和对照组（n = 10）。经过12周的运动计划后，将人体测量学、血液生化变量和身体素质成分与基线时获得的数据进行比较。在调整潜在混杂因素的同时，使用多元回归分析来评估不同类型的运动训练与HDL-C变化之间的关联。结果显示，以对照组作为比较对象，在调整潜在混杂因素后，联合运动训练组（β = 4.17，P < 0.0001）、有氧运动训练组（β = 3.65，P < 0.0001）和抗阻训练组（β = 2.10，P = 0.0001）的效果与HDL-C的增加呈正相关。我们的研究结果表明，短期运动计划在提高HDL-C水平方面可发挥重要作用，单独进行有氧运动或抗阻训练均可显著提高HDL-C水平，但有氧与抗阻联合训练的改善效果最为显著。
