| 摘 要： | 本实验选取雄性SD健康大鼠40只,随机分为4组,即常氧安静组、常氧运动组、低氧安静组、低氧运动组。常氧运动组每天在常氧动物跑台上以25m/min、60min/d、6d/w运动;低氧运动组每天在相当于海拔2500m低氧动物跑台上以20m/min、60min/d、6d/w运动,其余时间在常氧环境下居住。实验6周之后采样测试指标,低氧运动组与常氧运动组比较,血浆甘油三酯、低密度脂蛋白胆固醇的下降幅度和高密度脂蛋白的上升幅度都更明显,提示低氧运动对改善血脂代谢状态比常氧运动更为有效,更有利于外周组织胆固醇的清除,对防治动脉粥样硬化也更为有效。

| Abstract: | 40 male SD rats were randomly divided into 4 groups as following: Normoxic Control group, Normoxic exercise group, Hypoxic control group, Hypoxic exercise group. Normoxic exercise group was trained at treadmill 25m/min, 60min/d, 6d/w. Hypoxic exercise group was trained at 20m/min, 60min/d, 6d/w in hypoxic chamber. After 6 weeks experiment , triglyceride (TG) and LDL-cholesterol(LDL-C) decreased much, HDL-cholesterol(HDL-C) increased much higher in Hypoxic exercise group than Normoxic exercise group. All these suggest that Hypoxic exercise is better than normoxic exercise in improving blood lipid metabolism and eliminating cholesterol and it is a better way to prevent atherosclerosis. |
