目的:对高糖餐后进行急性有氧运动对高三学生血糖及胰岛素水平的影响进行分析探讨。方法:选择高三学生20名作为研究对象,对其展开平衡随机交叉自身对照实验,包括口服葡萄糖耐量试验(OGTT),在OGTT后立即开展45分钟的中等强度有氧运动(OGTT+EX)。采集受试者空腹以及服用葡萄糖1、2、3、4小时后的肘静脉血,对血糖、胰岛素水平进行检测,并展开对比分析。结果:OGTT+EX与OGTT试验1小时后的胰岛素水平比较存在明显差异(P<0.05);血糖水平比较无明显差异。结论:高糖餐后展开急性有氧运动可以对胰岛素水平升高进行有效的抑制,效果明显,值得关注。
OBJECTIVE: To analyze the effects of acute aerobic exercise on postprandial blood glucose and insulin levels in senior high school students after meal. METHODS: Twenty subjects from Grade 3 were enrolled in this study. They were randomized to cross-over self-controlled trials, including oral glucose tolerance test (OGTT) and moderate intensity aerobic exercise (OGTT + EX) for 45 minutes immediately after OGTT. The subjects were fasting and taking 1,2,4,4 hours after the elbow venous blood glucose, glucose and insulin levels were detected and compared. Results: There was a significant difference in insulin level between OGTT + EX and OGTT one hour later (P <0.05). There was no significant difference in blood glucose level between OGTT + EX and OGTT. CONCLUSION: Acute aerobic exercise after high glucose can effectively inhibit the increase of insulin level, which has obvious effect and deserves attention.
