This study was designed to examine the ability an endurance exercise training program to alter blood levels of cholesterol, HDL-cholesterol, LDL-cholesterol, and triglycerides in children. Thirty-one sixth grade students age 10-12 years (20 girls, 11 boys) who were healthy and active volunteered for participation. The training program consisted of 13 weeks of aerobic activities three days a week, 25 minutes per session, with training intensity assessed by heart rate monitors. Serum lipids and maximal oxygen uptake (VO2max) were measured at the beginning of a control period, 13 weeks later at the beginning of the training program, and at the termination of 13 weeks of training. VO2max values for the group improved 5.4%, but no significant changes were observed in any of the blood lipid levels between the control and training periods. These findings suggest that aerobic training of 13-weeks duration is not an effective means of altering blood lipids in healthy normolipemic children.
本研究旨在检验耐力运动训练计划改变儿童血液中胆固醇、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇和甘油三酯水平的能力。31名年龄在10至12岁的六年级健康活跃学生（20名女孩，11名男孩）自愿参与。训练计划包括为期13周的有氧运动，每周三天，每次25分钟，通过心率监测器评估训练强度。在对照期开始时、训练计划开始13周后以及13周训练结束时测量血清脂质和最大摄氧量（VO2max）。该组的VO2max值提高了5.4%，但在对照期和训练期之间，任何血脂水平均未观察到显著变化。这些发现表明，为期13周的有氧训练并非改变健康血脂正常儿童血脂的有效方法。
