Comparison of the Effects of Aerobic, Resistance, and Combined Exercise Training on Metabolic Syndrome Risk Factors Among Obese Young Men

Evidence suggests that regular exercise provides the beneficial effect of improved metabolic syndrome (MetS) on reducing cardiovascular disease risk. However, previous studies show conflicting results for this association between different types of exercise training (i.e., aerobic, resistance, or combined aerobic and resistance training). The purpose of this study was to determine which type of exercise training is more effective in improving MetS risk factors among obese young men in Taiwan. Forty obese young men were randomly assigned into 4 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). The training period was 12 weeks. The aerobic training was performed for 60 min/ session for 5 days/week with an intensity set at 50-70% of maximal heart rate (HR_(max)). The resistance training was performed for 60 min/day, 5 days/week with an intensity set at 50–80% of 1 repetition maximum (RM). The combined training included both aerobic (2 days in odd weeks; 3 days in even weeks) and resistance exercise (3 days in odd weeks; 2 days in even weeks). Demographic data, anthropometric assessments, blood biochemical parameters, and health-related physical fitness measurements were collected. The results showed that the MetS risk factors and health-related physical fitness measurements were found to be significantly improved after exercise training. The absolute changes in both fasting glucose (FG) and triglycerides (TG) after exercise program were -8.5% and -8.7% respectively for the combined training group, -5.6% and -7.0% for the aerobic training group, and -6.6% and -4.3% for the resistance training group. We conclude that the 12 weeks of exercise training significantly reduced both FG and TG levels among obese young men in Taiwan. The combined training regimen shows superior training effects on FG and TG levels to aerobic or resistance training alone.

規律運動已被證實可以改善代謝症候群徵狀進而降低罹患心血管疾病的風險。然而，過去研究在探討不同運動類型（有氧、阻力與有氧合併阻力運動訓練）介入對健康效益有不一致的研究結果。本研究主要目的為確定哪一種運動類型可以更有效的改善臺灣肥胖年輕男性代謝症候群危險因子。40位肥胖年輕男性被隨機分派為四組：有氧訓練組（n=10）、阻力訓練組（n=10）、有氧合併阻力訓練組（n=10）及對照組（n=10），運動訓練介入時間為期12週。有氧訓練組受試者進行每週5次、每次60分鐘，運動強度介於50～70%最大心跳率。阻力訓練組受試進行每週5次，每次60分鐘，運動強度介於50～80% 1 repetition maximum（RM）。有氧合併阻力訓練組包含有氧運動（單週有氧訓練2次，雙週訓練3次）和阻力訓練（單週訓練3次，雙週訓練2次）。所有受試者人口背景變項、體位量測、血液生化值及健康體適能檢測等皆進行前、後測資料收集與分析。研究結果發現運動訓練介入後受試者代謝症候群危險因子及健康體適能等指標具有顯著的改善。空腹血糖及三酸甘油酯的改變量比率，在有氧合併阻力運動訓練組分別為-8.5%和-8.7%；在有氧訓練分別為-5.6%和-7.0%；在阻力訓練組分別為-6.6%和-4.3%。本研究結論證實12週的運動訓練可以顯著降低臺灣肥胖年輕男性的空腹血糖及三酸甘油酯，有氧─阻力運動訓練對於肥胖者代謝症候群指標之空腹血糖及三酸甘油酯改善效果優於單一有氧或阻力運動訓練。
