本研究主要目的在探討12週健走訓練對大專超重女學生之身體組成及血脂濃度的影響。受試者選自元培科學技術學院體重控制班12名女同學，且（BMI＞25）的自願參加者（平均年齡18.67±0.29歲、身高156.36±3.32公分、體重61.67±1.00公斤、身體質量指數25.64±0.19kg/m[feb4]）。全體受試者同時接受12週的健走訓練（每週3次，每次60分鐘，運動強度介於55％至65％ HRmax），並於訓練前24小時及訓練後48小時各接受一次體重、BMI的測量與抽血檢驗，藉此觀察身體組成及體內總膽固醇、三酸甘油酯、高密度脂蛋白膽固醇及低密度脂蛋白膽固醇等血脂濃度的變化情形。結果顯示，12週中低強度規律性的健走運動訓練可以有效降低身體質量指數與達到降低三酸甘油酯及提升高密度脂蛋白膽固醇濃度的訓練效果，而在降低總膽固醇與低密度脂蛋白膽固醇的濃度上較不明顯。

The objective of this research is to discuss the effects of the 12-week walking training on body mass and density of cholesterol of overweight college female students. Twelve subjects were from the weight control class of Yuanpei University of Science and Technology with BMI greater than 25 (the average age of 18.67±0.29 years old; the average height of 156.36±3.32 cm; the average weight of 61.67±1.00kg; Body Mass Index of 25.64±0.19kg/m[feb4]). All subjects received a 12-week waking training (three times per week; 60 minutes each time; the exercise intensity was between 55% and 65% HRmax). Weight and BMI measurement and blood testing were conducted 24 hours prior to the training and 48 hours after the training, which were used to observe body mass and changes of density of Total Cholesterol, Triglyceride, High-Density Lipoprotein Cholesterol, Low-Density Lipoprotein Cholesterol. The results showed that 12-week middle or low intensity regular walking training can effectively improve body mass, lower Trig lyceride, and increase density of High-Density Lipoprotein cholester5ol. However, the walking training failed to show significant effect on lowering the density of Total Cholesterol and Low-Density Lipoprotein Cholesterol.
