体力劳动能力（PWC）是一种身体健康的衡量标准，通过自行车测力计对2,779名55岁以下的健康男性进行了评估，这些男性随后因症状性心肌梗死（MI）进行了平均4.8年的随访。有36个。根据心脏病的常规危险因素校正后，低于中位PWC的MI相对危险度（RR）为2.2（95%置信限，1.1和4.7）。这种增加的风险似乎仅限于同时存在某些其他风险因素的男性：高于中位数的胆固醇水平，吸烟，高于中位数的收缩压，或这些因素的组合。在至少有两个这些因素的男性中，低于中位数PWC的调整后RR为6.6（95%置信限，2.3和27.8）。身体素质差可能是心脏病的一个重要危险因素，特别是当传统的危险因素也存在时。
Physical work capacity (PWC), a measure of physical fitness, was assessed by bicycle ergometry on 2,779 healthy men younger than 55 years who were subsequently followed up for an average of 4.8 years for symptomatic myocardial infarction (MI). There were 36 MIs. The relative risk (RR) of MI for below median PWC, adjusted for conventional risk factors for heart disease, was 2.2 (95% confidence limits, 1.1 and 4.7). This increased risk appeared to be limited to men with certain other risk factors present simultaneously: above-median cholesterol level, smoking, above-median systolic BP, or a combination of these. Among men with at least two of these factors, the adjusted RR for below-median PWC was 6.6 (95% confidence limits, 2.3 and 27.8). Poor physical fitness may be an important risk factor for heart disease, especially when conventional risk factors are also present.
