Three hundred subjects undertook a submaximal bicycle ergometry procedure which was terminated at level 19 on the Borg perceived exertion rating scale. The findings indicated that the total work output was an effective reference criterion for each individual. Age and height were considerably more dominant than weight in affecting this output in both sexes. In women, however, the use of the maximum work load/maximum systolic blood pressure ratio gave the best explanation of variation. A numerical relative fitness ranking derived from the work output was developed to achieve comparison among subjects irrespective of age, height, weight and sex. This categorization revealed, interalia, that the average maximum systolic blood pressure was a major limiting factor in performance. Significant changes characteristic of ischaemia occurred in the electrocardiograms of a substantial proportion of subjects, including the apparently well, the proportion being higher in women than in men. There were definite differences between the ranked work load categories. The relative fitness ranking is of value in assessing a variety of factors affecting performance in heterogeneous populations, and also in following population responses to various procedures.
300名受试者进行了次极量自行车测力计测试，该测试在博格主观用力程度评级量表的19级时终止。研究结果表明，总功输出是每个个体的有效参考标准。在影响男女功输出方面，年龄和身高比体重的影响要大得多。然而，对于女性而言，最大工作负荷/最大收缩压比值能最好地解释其变化情况。为了在不考虑年龄、身高、体重和性别的受试者之间进行比较，根据功输出得出了一个数值化的相对健康状况排名。这种分类揭示，平均最大收缩压是表现的一个主要限制因素。相当一部分受试者的心电图出现了缺血特征性的显著变化，包括那些看似健康的受试者，女性中的比例高于男性。不同等级的工作负荷类别之间存在明显差异。相对健康状况排名对于评估影响异质人群表现的各种因素以及跟踪人群对各种程序的反应具有价值。
