材料和方法。12名年龄在18-32岁的男性参加并完成了这项低周自行车运动训练研究。所有人都不吸烟，通过身体检查和心脏病专家进行的跑步机测试发现没有心血管疾病。在训练计划之前，受试者没有参加常规活动，尽管他们偶尔会参加篮球等活动。所有受试者在研究前血浆总胆固醇、甘油三酯、高密度脂蛋白胆固醇和低密度脂蛋白胆固醇（LDLC）水平正常。没有糖尿病患者；没有人患有任何慢性疾病。他们没有服用任何药物，只有一名受试者在训练期间服用了几周的Tagamet。在训练前通过体格检查和心血管压力测试确定项目的资格后，在自行车测力仪上进行最大摄氧量测试（VO, max）(6)，并根据水下称重确定的体密度计算体脂，使用Siri公式（30）。运动训练包括有监督的自行车测力计计划，连续30分钟平均70%最大心率（HR）储备[静息HR加上0.7（最大HR-静息HR）]。在监测心率时，受试者每5分钟停止运动10秒。受试者每周锻炼3次，持续10周，并定期增加工作量以维持目标hr。在训练计划结束时重新确定身体健康和人体测量变量。
MATERIALS AND METHODSSubjects. Twelve men, ages 18-32 yr, participated in and completed the lo-wk bicycle exercise training study. All were nonsmokers and were found free of cardiovascular disease by physical examination and by a treadmill test administered by a cardiologist. Subjects were not engaged in regular activity prior to the training program, although they participated in occasional activity such as basketball. All subjects had normal prestudy levels of plasma total cholesterol, triglyceride, HDLC, and lowdensity lipoprotein cholesterol (LDLC). None were diabetic; none had any chronic diseases. They took no medications, with the exception of one subject who was on Tagamet for several weeks during the training program.Trainingprogram. After determining eligibility for the program by physical examination and by cardiovascular stress test in the pretraining period, a maximum oxygen uptake test (VO, max) was performed on a bicycle ergometer (6) and body fat was calculated from body density determined by underwater weighing using the equation of Siri (30). Exercise training consisted of a supervised bicycle ergometer program with a continuous 30-min workout averaging 70% maximum heart rate (HR) reserve [resting HR plus 0.7 (maximum HR-resting HR)]. Subjects stopped exercising only for 10 s each 5 min while HR was monitored. Subjects exercised three sessions/wk for 10 wk, and work loads were increased regularly to maintain target HRs. Physical fitness and anthropometric variables were redetermined at the end of the training program.
