This study (1) describes a treadmill walking protocol which has been used safely in over 40,000 tests since 1960, (2) presents normative data on oxygen consumption (VO2) so that it may be determined from work load without direct measurement, and (3) demonstrates simple techniques for early activity prescription or later therapeutic walking programs for patients after myocardial infarction (MI) based on this treadmill test. Normative data are presented on 131 subjects. There were no significant differences in VO2 values at the various work loads dependent on age, gender, fitness level, familiarity with the test procedure, clinical status, or the presence or absence of beta blockade. The protocol was then applied in cardiac rehabilitation of 25 patients. As a low level test, in 2 to 9 minutes patients attained 56 to 83% of age-predicted maximal heart rate. The translation of these data into early activity guidelines is shown. For a walking program, the maximal speed attained at 10% grade on the treadmill when walked on level ground put patients in the target heart rate zone for cardiovascular conditioning.
（1）描述了一种自1960年以来已在40000多次测试中安全使用的跑步机步行方案；（2）给出了耗氧量（VO2）的标准数据，以便无需直接测量即可根据工作量确定耗氧量；（3）展示了基于此跑步机测试为心肌梗死（MI）患者制定早期活动处方或后期治疗性步行计划的简单技术。给出了131名受试者的标准数据。在不同工作量下，VO2值在年龄、性别、健康水平、对测试程序的熟悉程度、临床状态或是否使用β受体阻滞剂方面均无显著差异。然后将该方案应用于25名患者的心脏康复。作为一项低水平测试，患者在2至9分钟内达到了年龄预测最大心率的56%至83%。展示了将这些数据转化为早期活动指南的情况。对于步行计划，在跑步机上以10%坡度行走时达到的最大速度，当在平地上行走时可使患者处于心血管调节的目标心率区域。
