|Abstract:||本研究主要目的探討不同強度阻力訓練對代謝症候群危險因子大學男性血脂肪、身體組成與脂肪代謝激素之影響。本研究招募30位大學（18－22歲）具有代謝症侯群危險因子且無規律運動之男性，隨機分成高阻力訓練組、中阻力訓練組和控制組三組，每組10位。高阻力強度為4－8 RM (Repetition Maximum，最大反覆次數)；中阻力強度為8－12 RM，訓練組受試者接受每週3天，回合數 (set) 3次，全身8－9個主要肌肉群，維持10週的漸增式阻力訓練；每週總訓練量相同 (總訓練量 = 每週訓練組數 × 個體相對負荷 ( %1RM ) × 每組反覆次數)。所有受試者於訓練前後檢測代謝症候群相關變項，包含腰圍、血壓、血脂、空腹血糖，身體組成包含脂肪及肌肉量、脂肪及肌肉百分比、去脂體重及脂肪代謝相關激素包含胰島素、脂聯素、瘦體素。所得資料以混合設計單因子共變數分析 ( onw-way ANCOVA，mixed design) 處理。結果顯示在代謝症候群因子變項主要效果比較，在腰圍方面，高強度組顯著比控制組與中強度組低 ( p< .05)；在三酸甘油脂與高密度脂蛋白膽固醇，高強度組與中強度組皆顯著優於控制組 (p < .05)；在低密度脂蛋白膽固醇，高強度組與中強度組顯著比控制組高 (p < .05)；在舒張壓，高強度組顯著比控制組低 (p < .05)。在身體組成變項主要效果比較，在脂肪量，高強度組與中強度組顯著比控制組低 (p < .05)；在肌肉量、去脂體重和肌肉百分比，高強度組與中強度組皆顯著比控制組高 (p < .05)；在脂肪百分比，高強度組顯著比控制組低；在腰臀圍比，高強度組顯著比控制組低 (p < .05)。在脂肪代謝激素變項主要效果比較，在胰島素，高強度組與中強度組顯著比控制組低 (p < .05)；在脂聯素方面，高強度組顯著比控制組低 (p < .05)。結論：十週中強度與高強度相同總訓練量的阻力訓練對於代謝症候群危險因子大學男性的大部分相關健康變項 (血脂肪，身體組成與脂肪代謝激素)皆有正面的助益，高強度阻力訓練對於腰圍、脂肪百分比、舒張壓和脂聯素的影響較大。|
Purpose :The purposes of this study were to investigate the effects of different intensity resistance training of male university students with risk factors of metabolic syndrome on blood lipids, body composition and the hormones related to fat metabolism. Subjects :Thirty male university students (aged from 18－22 years) with risk factors of metabolic syndrome and non-regular exercise habits were recruited as the subjects of this study. Method : The subjects were randomly assigned into high intensity group (H), medium intensity group (M) of resistance training and control group (C), each group comprised of 10 subjects. The high intensity and medium intensity of resistance training were 4－8 RM (repetition maximum) and 8－12 RM, respectively. The training subjects had received 3 days per week, 1－3 sets, 9 major muscle groups of progressive resistance training for 10 weeks, with the same total amount of training volume ( frequency * load * sets ). All the subjects had received the related health variables tests, including waist circumference, fasting blood glucose, blood pressure, body composition and hormones of fat metabolism (Insulin, Leptin, and Adiponectin) before and after 10 weeks of training. All the collected data were analyzed with mixed design one way ANCOVA. Results : The results of this study were followed: 1, main effects of metabolic syndrome: the waist circumference of H was significantly lower than that of M and C (p<.05). The HDL-C of H and M were significantly better than that of C (p <.05). The DBP of H was significantly lower than that of C (p <.05). 2, main effects of body composition: the fat mass of H and M subjects were significantly lower than that of C (p <.05). The muscle mass, % muscle mass, and fat-free mass of H and M were significantly higher than that of C (p<.05). 3, main effects of hormones of fat metabolism: the insulin of H and M were significantly lower than that of C (p <.05). The adiponectin of H was significantly lower than that of CG (p<.05). Conclusion: The high and medium intensity of 10-week resistance training with same amount of training volume both have produced favorable health effects of male university students with risk factors of metabolic syndrome. The high-intensity has greater effects on waist circumference, % body fat, DBP and adiponectin.
