The Army Combat Fitness Test (ACFT), consisting of deadlift, standing power throw, hand release push-up, sprint-drag-carry, leg tuck or plank, and 2-mile run, is the United States Army's new fitness test. The ACFT is designed to measure multiple fitness components required to perform combat tasks. One critical task is the tactical foot march (TFM), where soldiers cover long distances while carrying loads comprised of mission-essential equipment. As the ACFT is meant to predict soldier task performance, determining the relationships between the ACFT and the TFM is important. Data from 29 cadets (♂ = 20, ♀ = 9) from one university Reserve Officers' Training Corps program were analyzed. The ACFT was recorded in raw and scaled scores. The TFM was performed over 6.44 km, with time recorded. Cadets carried a 15.88-kg rucksack, fighting load carrier, 3-L hydration pack, and replica M4 carbine. Independent samples t-tests evaluated ACFT and TFM between-sex differences. Partial correlations, controlling for sex, determined ACFT event and TFM relationships. Male cadets outperformed females in all ACFT tasks ( ≤ 0.039), except the push-up. ACFT total score, leg tuck, 2-mile run, and sprint-drag-carry showed large correlations with the TFM ( = ±0.463-0.531, ≤ 0.026). Aerobic and anaerobic capacity and upper body/trunk strength were important fitness components for cadet TFM performance.
陆军战斗体能测试(ACFT)包括硬拉、立定投力、双手放开俯卧撑、冲刺-拖拽-搬运、腿部卷腹或平板支撑以及2英里跑,是美国陆军的新体能测试。ACFT旨在测量执行战斗任务所需的多种体能要素。一项关键任务是战术徒步行军(TFM),即士兵在携带由任务必需装备组成的负载时长途行军。由于ACFT旨在预测士兵的任务表现,确定ACFT与TFM之间的关系很重要。对来自一所大学后备军官训练团项目的29名学员(男=20,女=9)的数据进行了分析。记录了ACFT的原始分数和换算分数。TFM在6.44公里的路程上进行,并记录了时间。学员们携带一个15.88公斤的背包、战斗负载携行具、3升水合背包和M4卡宾枪复制品。独立样本t检验评估了ACFT和TFM的性别差异。控制性别后的偏相关分析确定了ACFT项目与TFM之间的关系。除俯卧撑外,男学员在所有ACFT任务中的表现均优于女学员(≤0.039)。ACFT总分、腿部卷腹、2英里跑和冲刺-拖拽-搬运与TFM显示出高度相关性(=±0.463 - 0.531,≤0.026)。有氧和无氧能力以及上身/躯干力量是学员TFM表现的重要体能要素。
