中文摘要 | 本篇實驗目的主要在於對不同活動程度者或肥胖者熱量消耗的評估。受試者來自一般大學和體育院校學生共四名。年齡在20-27歲。根據三天的活動記錄,來區分受試者為三組:輕度、中度和重度活動程度,又依據理想體重百分比大於25為第四組。每組十名,四組共四十名。受試者以Gould 2900,心肺功能分析儀分別測量基礎代謝率(BMR)飲食生熱效應(DIT)並以因素加算法(Factorial Method.推算不同組之能量消耗之差異。有關身體組成的評估,使用生物電阻體脂肪分析(BIA)測量體脂肪百分比和去脂體重(LBM)。結果顯示輕度活動程度組總能量消耗平均為34.9kcal/kg/d,一天總能量消耗值平均為2110kcal,基礎代謝率1274kcaI,飲食生熱效應237kcal,活動量消耗值599kcal。中度活動程度組總能量消耗平均為39.8kcal/kg/d,一天總能量消耗值平均為2761kcal,基礎代謝率1411kcaI,飲食生熱效應269kcal,活動量消耗值1081kcal。重度活動程度組總能量消耗平均為46.9kcal/kg/d,一天總能量消耗值平均為3312kcaI,基礎代謝率1613kcal,飲食生熱效應200kcal,活動量消耗值1501kcal。肥胖組大於理想體重百分比25以上,總能量消耗平均為34.0kcal/kg/d,肥胖組的體脂肪百分比為25.2,顯著高於其他三組(p<0.05),而去脂體重67.0Kg,顯著高於輕度活動程度組。肥胖組總能量消耗值平均為2908kcal,基礎代謝率1731kcal,飲食生熱效應134kcal,活動量消耗值1071kcal。由實驗前、實驗後,兩個月以上的時間,受試者平均體重前後改變無顯著性,可推知實驗期間能量攝取、能量消耗兩者間無顯著差異。本研究中以40名男性受試測量結果求得、基礎代謝率(BMR)和去脂體重(LBM) 之相關係數為r=0.85。 |
英文摘要 | The purpose of this study was to estimate the energy expenditure of various physical activity levels and of obese college students. Forty male non-PEmajored College and Physical Enducation (PE) majored students) aged from 20 to 27 years old, participated in the study. Subjects were assigned to four groups according to their weights and daily physical level. Group I comprised of those with Light Physical Activity Level (LPAL); Group 2 of Medium Physical Activity Level (MPAL). Group 3 of Heavy Physical Activity Level (HPAL) and Group 4was composed of obese subjects, identified as those with body weight exceeding 25 of ideal body weight. Basal metabolic rate (BMR) and dietary induced thermogenesis (DIT) were assessed by indirect calorimetry using the Gould 2900 in all subjects. Investigated the difference of energy expenditure of groups by using Factorial Method. Percent body fat and lean body mass (LBM) were estimated from Biological Impedance Analysis (BIA). Result shows that the mean energy expenditure of Groups 1) 2, 3 and 4 are34.9, 39.8, 46.9 and 34.0 kcal/kg/d, respectively, as for the 24-hour total energy expenditure, BMR, DIT and PA the values are as follows for Group 1, 2110 kcal,1274 kcal, 237 Kcal and 599 kcal; for Group 2, 2761 kcal, 1441 kcal, 269 kcal and 1081 kcal; for Group 3, 3312 kcal, 1613 kcal, 200 kcal and 1501 kcal and for Group 4, 2908 kcal, 1731 kcal, 134 kcal and 1071 kcal. In the obese group, percent of body fat was 25.2, a value being significantly greater than the other three groups. Their LBM was 67.0 kg and this was significantly greater than that of the LPAL group. The results show that there was no significant difference between energy expenditure and energy intake. Correlation of BMR and LBM is r= 0.85. |
