中強度運動前增補黑木耳對血脂和血糖之影響

目的：探討短期從事中等強度運動前增補黑木耳膳食纖維對血脂及血糖之影響。方法：召募24名BMI≧22的健康大學女生，以雙盲、平衡次序實驗設計的方式，進行5天在運動前60分鐘分別增補含有10g黑木耳膳食纖維飲品(AAE組；8名)或安慰劑糊精飲品(PLAE組；8名)，安靜休息後，從事50~60%HRR水平坡度原地跑步機運動30分鐘，此外，第3組則僅增補黑木耳飲品(AA組；8名)，且無運動介入。在正式實驗前空腹8小時(Pre)，以及實驗第1天(D1)和第5天(D5)服用黑木耳飲品後第90、120分鐘，採集血液測量三酸甘油脂(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)和血糖(BG)，所得數據以混合設計二因子變異數分析進行統計考驗，顯著水準訂為α=.05。結果：在不同時間點方面，AAE組和AA組除LDL-C未達顯著差異(p＞.05)外，TG、TC、HDL-C與BG濃度皆有顯著差異(p＜.05)。TC和BG於實驗處理與時間的交互作用均達顯著(p＜.05)。結論：短期增補黑木耳可能有效降低總膽固醇濃度，再加以搭配中等強度運動後則可提升其改善效果；此外，短期從事中強度運動，亦可有效改善血糖濃度。

Purpose: To discuss the effect of taking Auricularia auricular prior to moderate-intensity exercise on blood lipid and blood glucose. Methods: Twenty-four healthy female university students (BMI≧22) were assigned to 3 groups based on the experiment design of double-blind and balance order. In five consecutive days, 60 minutes prior to doing exercise, one group of subjects took a drink containing 10g A. auricular (AAE group; n=8) and the other group of subjects took a drink containing placebo (PLAE group; n=8). After taking some rest, they had 30 minutes of treadmill sport at in 50-60% HRR flat slope. In addition, the third group of subjects only took drink containing (AA group; n=8) and did not have any exercise. Five blood samples were collected from each subject, sampling times are as follows: prior to formal experiment (Pre), empty stomach sampling; the first day of the experiment (D1) and the fifth day of the experiment (D5), collecting samples respectively at 90 minutes and 120 minutes after taking a drink. Blood analysis was made on the following items: total triglyceride (TG), total cholesterol (TC), high- density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and blood glucose (BG). The data obtained were in the statistical test with mixed design 2-way ANOVA, the significant level was set as α = .05. Results: The interaction of experimental processing TC, BG and time reach significant (p＜ .05). Among different timing points, TG, TC, HDL-C and BG of AAE group and PLAE group, except for LDL-C not reaching significant difference (p＞ .05), all had a significant difference (p ＜.05). Conclusions: The study suggested that short-term supplement of A. auricular may have effects of reducing total cholesterol, if we incorporate it with a moderate-intensity exercise, it would improve effects accordingly. The benefits of the short-term moderate-intensity exercise also have increased the consumption of blood glucose.
