本研究目的為比較有氧訓練、阻力訓練及綜合訓練介入前、後血壓的改善情形。 研究對象為中華大學40名男性肥胖(身體質量指數孟27kg/m2)大專生，平均年齡18.7士0.3歲，平均身體質量指數30.8士0.5 kg/m2。依隨機分派的方式，區分為有 氧訓練組(n=10)、阻力訓練組(n=lO)、綜合訓練組(n=lO)與對照組(n=IO)' 有氧訓練每週接受5天有氧訓練，每次60分鐘，運動強度介於50%-70%最大心跳率(m位imalheart rate， HRmax)。阻力訓練組每週實施5天阻力訓練，1-4週其負荷 強度為50%-60%1 RM (repetition maximum) ; 5-8週其負荷強度為60%-70% 1 RM ; 9-12週其負荷強度為70%-80% lRM的負荷強度，每組反覆次數8-15次，每次訓練 2-3組，每次實施10個動作項目。綜合訓練組每週實施5天綜合訓練。對照組則維 持正常的日常生活作息。12週運動訓練介入前、後進行體位評估、血壓量測以及健康體過能檢測。研究結果如下:有氧訓練組、阻力訓練組與綜合訓練組對收縮壓、舒張壓、登階測驗、坐姿體前彎、一分鐘仰臥起坐及身體質量指數前、後測數值皆有改善且達統計顯著性(p< 0.05)。有氧訓練組、阻力訓練組與綜合訓練組對收縮 壓與舒張壓的調控成效在三組間則無顯著差異。

The purpose of this study was to determine the effects of aerobic training, resistance training, and combined training on blood pressure in obese adults. Forty obese [body mass index (BMI), 27 kg/m^2] male subjects, aged 18-29 years, were randomized into four groups: an aerobic training group (n=10), a resistance training group (n=10), a combined training group (n=10), and a control group (n=10). The aerobic training was composed of 50-70% maximal heart rate (HRmax), 60 min/day, 5 days/week. The resistance training was performed for 60 mim/day, 5 days/week, at the maximum rate of 50-60% of one-repetition (1-RM) during weeks 1-4, 60-70% of 1-RM during weeks 5-8, and 70-80% of 1-RM during weeks 9-12. The combined training was separated into aerobic training (2 days of a single week; 3 days of a double week) and resistance training (3 days of a single week; 2 days of a double week). All subjects' blood pressure, and components of physical fitness were measured at baseline after 12 weeks of exercise training, and the components of health related fitness were found to be significantly improved (p＜0.001). The absolute changes in both blood pressure and the components of health related fitness after the 12-week exercise program were non-significant difference for each training group. In conclusion, our results showed that aerobic, resistance and combined training led to greater improvements in blood and health related fitness.
