This paper examines the literature on the Army Physical Fitness Test (APFT) as a measure of aerobic capacity and muscular strength/endurance. The APFT consists of a two-mile run, push-ups, and sit-ups. The two-mile run is a measure of aerobic fitness because this test is highly correlated with maximal oxygen uptake (VO2max). Muscular strength and absolute muscular endurance are highly correlated, justifying the use of a single measurement for both. Studies using factor analysis showed that push-ups and sit-ups have moderate to high factor loadings on various muscular strength/endurance factors. However, there are methodological problems in relating these studies to the APFT.
本文考察了将陆军体能测试（APFT）作为有氧能力及肌肉力量/耐力衡量指标的相关文献。APFT包括两英里跑、俯卧撑和仰卧起坐。两英里跑是有氧适能的一项衡量指标，因为该测试与最大摄氧量（VO2max）高度相关。肌肉力量与绝对肌肉耐力高度相关，这使得对两者采用单一测量方法具有合理性。使用因素分析的研究表明，俯卧撑和仰卧起坐在各种肌肉力量/耐力因素上具有中度至高因素负荷。然而，将这些研究与APFT联系起来存在方法上的问题。
