本研究探討12週運動訓練介入對降低腹部內臟脂肪量的效果，以24位國立屏東教育大學學生為研究對象，均未受過訓練且身體質量指數＞24kg/平方公尺，分配12人至運動訓練組（E組）及12人至控制組（C組）。E組的運動強度為攝氧峰值的70%、每週三天為期十二週，每次45分鐘的騎腳踏車訓練，C組需維持正常飲食及作息。訓練前、後分別進行一次測驗包括（一）身體組成：體重、BMI、體脂肪百分比、三圍、皮脂肪厚度及應用MRI技術來測量腹部總脂肪橫切面積、腹部皮下脂肪橫切面積、腹部內臟脂肪橫切面積等。（二）心肺功能：安靜心跳率、安靜血壓值、攝氧峰值。（三）血脂分析：三酸甘油酯(TG)、總膽固醇(TC)、高密度脂蛋白膽固醇(HDL-C)、低密度脂蛋白膽固醇(LDL-C)、總膽固醇與高密度脂蛋白膽固醇比值(TC/HDL-C)、胰島素(Insulin)。統計方法以共變數分析(one-way ANCOVA)考驗二組的前、後測是否有顯著的介入效果。結果發現E組在腰圍改變值、攝氧峰值相對值、攝氧峰值絕對值、血中HDL-C量、Insulin等均顯著優於控制組(p<.05)。運動訓練可改善腰圍、增加攝氧量，並對血脂有改善效果和降低Insulin，這樣的改善效果有助於心血管疾病、糖尿病及肥胖的預防。

The purpose of this study was to examine the effects of 12 weeks exercise training on visceral fat in overweight university students. Twenty-four untrained healthy students and BMI >24 were recruited as subjects from the National Ping Tung University of education and randomly assigned to two groups. The exercise training group (Group E) were asked to perform 3 days per week, duration increased from 20 to 45 minutes gradually each session at 70% of VO(subscript 2peak) of bicycle exercise. Control group (Group C) were asked to maintain their habitual lifestyle throughout the whole period of the study. All subjects underwent the following measurements: weight(WT), body mass index(BMI), percent body fat(PBF) by underwater weight, visceral adipose tissue (VAT), subcutaneous adipose tissue(SAT) and total abdominal fat(TAF) assessment by magnetic resonance imaging (MRI), rest heart rate, rest blood pressure, VO(subscript 2peak), and blood lipid profiles such as TG, TC, HDL-C, LDL-C, TC/HDL-C, and Insulin were evaluated before and after 12 weeks exercise training. The data were analyzed by one-way ANCOVA to examine any changes after the training. The statistical significance was determined at the .05 level. The results showed that there were significant improvement in weist, VO(subscript 2peak), HDL-C, and Insulin in Group E after 12 weeks exercise training. We concluded that exercise training may reduce body fat, increase oxygen comsumption, lower blood lipids and insulin. The results could decreased the risk of cardiovascular disease, diabete, and obesity.
