The relationships between physical working capacity (PWC), level of habitual activity, relative leanness-fatness, isometric strength and motor ability have been examined in 85 17 and 18 year-old school boys. Level of habitual activity was found to be significantly related to PWC and to the strength and motor ability scores, whilst relative leanness-fatness was not significantly related to any of the other variables studied. Some of the apparent association between PWC and the strength and motor ability scores was due to a common dependence on body size, but the relationship between PWC and four performance variables remained significant when the influence of differences in size of the subjects was removed. It is suggested that differences in the level of habitual activity of post adolescent male school boys influence the physical working capacity but not relative leanness-fatness. The association between level of habitual activity and strength and motor ability scores suggests that the latter variables may possibly influence the level of habitual activity in this type of subject.
对85名17岁和18岁的男学生的体力工作能力（PWC）、日常活动水平、相对瘦胖程度、等长肌力和运动能力之间的关系进行了研究。结果发现，日常活动水平与PWC、力量和运动能力得分显著相关，而相对瘦胖程度与所研究的其他任何变量均无显著关系。PWC与力量和运动能力得分之间的一些明显关联是由于对身体大小的共同依赖，但当消除受试者体型差异的影响时，PWC与四个表现变量之间的关系仍然显著。研究表明，青春期后男性学生日常活动水平的差异会影响体力工作能力，但不会影响相对瘦胖程度。日常活动水平与力量和运动能力得分之间的关联表明，后两个变量可能会影响这类受试者的日常活动水平。
