The response of serum lipids and lipoproteins to high intensity endurance training was studied in 12 males. Nine additional subjects were assigned to a control group. The mean age of participants was 25.0 years. Members of the exercise group trained on a bicycle ergometer at a power output equivalent to 80% of maximal oxygen uptake (VO2max), 4 times per week for 30 minutes, for 9 weeks. Nine weeks of detraining followed. Fasting blood samples and maximum bicycle tests were administered prior to the program, and at 3 week intervals, for determination of serum triglyceride, cholesterol, HDL-cholesterol, (VLDL + LDL) cholesterol, the ratio of HDL-cholesterol to total cholesterol, and VO2max. Per cent body fat, caloric intake, and the composition of the diet were also assessed during the training and detraining periods. Analysis of variance revealed no significant difference between or within groups for the lipid variables, per cent body fat, or diet parameters. A significant group X time interaction occurred in VO2max (p less than 0.05) indicating a cardiovascular training effect. These data suggest that 9 weeks of high intensity endurance training may not alter lipid or lipoprotein metabolism.
对12名男性进行了血清脂质和脂蛋白对高强度耐力训练反应的研究。另外9名受试者被分配到对照组。参与者的平均年龄为25.0岁。运动组的成员在自行车测力计上进行训练，功率输出相当于最大摄氧量（VO2max）的80%，每周4次，每次30分钟，持续9周。随后是9周的停训期。在训练计划开始前以及每隔3周采集空腹血样并进行最大自行车测试，以测定血清甘油三酯、胆固醇、高密度脂蛋白胆固醇、（极低密度脂蛋白+低密度脂蛋白）胆固醇、高密度脂蛋白胆固醇与总胆固醇的比值以及VO2max。在训练期和停训期还评估了体脂百分比、热量摄入和饮食组成。方差分析显示，脂质变量组间和组内、体脂百分比或饮食参数均无显著差异。VO2max出现了显著的组×时间交互作用（p<0.05），表明有心血管训练效果。这些数据表明，9周的高强度耐力训练可能不会改变脂质或脂蛋白代谢。
