It has been shown that low glycemic index (LGI) diet can help reduce plasma levels of lipid, glucose, and insulin in healthy people or patients with hyperlipidemia, diabetes, and cardiovascular disease. Consuming LGI diet before exercise resulted in higher fat oxidation than HGI diet. However, little is known regarding the effect of diets with different and exercise on postprandial lipid metabolism. The purpose of this study was to exam the effect of diets with different GI and exercise for 3 days on postprandial lipid metabolism. The subjects were 6 healthy males without regular exercise. A cross-over experimental design was used. All subjects performed 4 different treatments, including LGI, high glycemic index (HGI), LGI diet and exercise (LGI+EX), and HGI diet and exercise (HGI+EX). The estimated GI value for LGI and HGI diets were 40 and 80, respectively. The exercise protocol was brisk walking at 50% VO2max for 60 min. On the fourth day oral fat tolerance test (1.2g fat, 1.1g carbohydrate, 0.33g protein / kg body mass) was performed. Blood samples were collected in 0, 30, 60, 120, 180, 240, and 300 min after consuming the test meal. Plasma levels of glucose, total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), and triglyceride (TG) were analyzed. TG concentration showed treatment and time effects. TG concentrations were significantly lower in HGI+EX group at 0 and 30 min than those in LGI group. TG concentrations HGI+EX group had lower TG incremental area under the curve (IAUC) than LGI+EX group. TC concentration showed treatment and time effects. HGI and HGI+EX groups showed lower TC levels than LGI group at 0 min, while HGI+EX group was lower than LGI group at 30, 180, and 240 min. HGI group had lower TC level than LGI group at 120 min. There was only time effect in HDL-C concentration. LDL-C concentration showed an interaction effect of treatment and time. LDL-C levels were lower in HGI and HGI+EX groups than LGI group at 0 min, while lower in HGI+EX groups than LGI groups at 30 and 60 min. Glucose IAUC was the lowest in HGI group, while insulin IAUC was the lowest in LGI+EX group, compared to other 3 groups. The results of this study suggested that exercise may reinforce the effect of diets with different GI values on postprandial lipid metabolism. Diet along did not affect the changes in TG concentrations after a test meal. However, the 2 exercise groups showed lower postprandial TG levels compared to the non-exercise groups.第壹章 緒論……………………………………………………01 一、研究背景…………………………………………………01 二、研究目的…………………………………………………01 第貳章 文獻回顧………………………………………………03 一、餐後脂質代謝與心血管疾病……………………………03 二、運動與餐後脂質代謝……………………………………04 三、運動降低餐後TG的機轉…………………………………08 四、不同G I飲食對餐後脂質代謝的影響……………………11 第參章 研究方法………………………………………………14 一、實驗對象…………………………………………………14 二、實驗設計…………………………………………………14 三、飲食控制…………………………………………………14 四、運動介入…………………………………………………15 五、OFTT與血液分析…………………………………………15 六、統計分析…………………………………………………19 第肆章 結果……………………………………………………20 一、受試者基本資料…………………………………………20 二、血液生化值………………………………………………20 第伍章 討論……………………………………………………22 參考文獻…………………………………………………………43398331 bytesapplication/pdf升糖指數;三酸甘油酯;餐後脂肪代謝;口服脂肪耐受度測試glycemic index;triglyceride;postprandial lipid metabolism;oral fattolerance test不同升糖指數的飲食與運動對脂質代謝影響The effects of diets with different glycemic index and exercise on postprandial lipid metabolismthesis
