摘要

本研究探討12週運動訓練及飲食教育計畫介入對體重過重大學生之影響，以36位國立屏東師範學院的健康學生為研究對象，均未受過訓練且身體質量指數(BMI) > 24，分配12人至運動訓練組(E組，6男6女)、12人至運動訓練+飲食教育組(E+D組，5男7女)及12人至控制組(C組，8男4女)。E及E+D組的運動強度為攝氧峰值的70%、每週三天為期十二週，每次由20分鐘漸增至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、後及停訓12週後分別進行一次測驗，項目包括：體重、BMI、攝氧峰值、水中秤重法量體脂肪百分比及應用MRI技術來測量人體內臟脂肪量、血液分析三酸甘油酯(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)、尿酸(UA)及胰島素(Insulin)，統計方法以共變數分析(one-way ANCOVA)及二因子混合設計變異數分析考驗三組的前、後測及追縱是否有顯著的介入效果。結果發現12週的介入計畫後，E+D組的體重、BMI、體脂肪百分比、Insulin、皮下脂肪橫切面積、內臟脂肪橫切面積、總脂肪橫切面積均顯著的下降，而攝氧峰值相對值及HDL-C均顯著的上升(p<0.05)，且此改善效果在體重、BMI、體脂肪百分比、Insulin、攝氧峰值相對值、皮下脂肪橫切面積、內臟脂肪橫切面積、總脂肪橫切面積均有延續至停訓十二週後的現象。運動訓練配合飲食教育介入計畫是長期體重控制的有效方法，可改善體重過重者的身體組成、心肺耐力、血液分析值及腹部脂肪量。

The purpose of this study was to examine the effects of 12 weeks exercise training and diet education on selected parameters of overweight university students. Thirty six untrained healthy students and BMI >24 were recruited as subjects from the National Ping Tung Teachers College and assigned to three groups. The training group (Group E), exercise training and diet education group (Group E+D) and control group (Group C) included 6 male and 6 female, 5 male and 7 female and 8 male and 4 female, respectively. All the subjects were asked to maintain their habitual lifestyle throughout the whole period of the study. The 12 weeks exercise training program was performed 3 days per week, duration increased from 20 to 45 minutes gradually each session at 70% of VO2peak of bicycle exercise. All subjects underwent the following measurements: weight(WT), body mass index(BMI), VO2peak, 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) and blood lipid profiles were evaluated before, after 12 weeks exercise training and follow 12 weeks detraining. The data were analyzed by one-way ANCOVA and Two-way analysis of variance(Group×time) with repeated measures to examine any changes after training and follow detraining. Within and among the trail, a statistical decrease (p<0.05) in WT, BMI, PBF, Insulin, VAT, SAT and TAF was observed in Group E+D. An increase (p<0.05) in VO2peak and HDL-C was observed in Group E+D.The improvement of WT, BMI, PBF, VO2peak, Insulin, VAT, SAT and TAF continued to exist after 12 weeks of detraining. Exercise training and diet education was a good method for long-term weight control of overweight university students in body composition, cardiovascular endurance fitness, blood parameters and abdominal fat distribution.
