本文观察了游泳运动对摄取高脂饲料大鼠血清高密度脂蛋白胆固醇(HDL-C)及高密度脂蛋白胆固醇/总胆固醇(HDL—C/TC)百分比值的影响。52头雄性成年大鼠分为四组:对照组(高脂饲料)、运动1组(高脂饲料+强制游泳0.5小时/天)、运动2组(高脂饲料+强制游泳2小时/天)和运动8组(高脂饲料+强制游泳4小时/天),每周游5天,连续3周。实验高脂饲料配方为:基础饲料93％,椰子油5％、胆固醇1.5％和胆盐0.5％。结果表明,高饱和脂肪和高胆固醇饲料引起血清TC升高,HDL-C和HDL-C/TC百分比值降低。游泳运动则可减轻体重,降低血清TC水平,显著地升高HDL-C和HDL-C/TC百分比值(P<0.001)。显示HDL-C的升高幅度与一定的运动时间延长有关。可见适宜的运动能改善高脂饲料所致的血脂异常。
In this paper, we observed the effects of swimming exercise on the serum high-density lipoprotein cholesterol (HDL-C) and high-density lipoprotein cholesterol/total cholesterol (HDL-C/TC) percentages in high-fat diet rats. Fifty-two male adult rats were divided into four groups: control group (high-fat diet), exercise group 1 (high-fat diet + forced swimming 0.5 hours/day), and exercise 2 group (high-fat diet + forced swimming 2 hours/day). And exercise 8 groups (high-fat feed + forced swimming 4 hours/day), 5 days per week for 3 weeks. The experimental high-fat diet formula was: basic feed 93%, coconut oil 5%, cholesterol 1.5% and bile salt 0.5%. The results showed that high saturated fat and high cholesterol diets caused elevated serum TC, and the percentages of HDL-C and HDL-C/TC decreased. Swimming exercise reduced body weight, lowered serum TC levels, and significantly increased HDL-C and HDL-C/TC percentage values (P<0.001). It shows that the increase of HDL-C is related to the extension of a certain exercise time. It can be seen that proper exercise can improve the dyslipidemia caused by high-fat diets.
