摘要

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.
