Relationships between the Army Combat Fitness Test scoring structure and laboratory measurements of physical fitness in reserve officer training corps cadets. J Strength Cond Res 39(7): 798-808, 2025-The Army Combat Fitness Test (ACFT) assesses aerobic and anaerobic fitness capabilities in the U.S. Army. The aim of this study was to evaluate the association between raw and composite ACFT scores and laboratory-based measurements of fitness. Nineteen Reserve Officers' Training Corp cadets performed a battery of laboratory-based fitness testing. Tests included a movement screening (Fusionetics), countermovement jumps, and maximal isometric mid-thigh pulls on portable force plates to determine power and strength. A Wingate test involving maximal cycling for 30 seconds was used to determine peak and mean power. On a separate day, cadets completed body composition and a graded exercise test on a motorized treadmill to determine peak oxygen uptake (V̇ o2 peak). Pearson correlations and partial corrections with 2000 bootstraps were used to compare ACFT scores (raw, composite, gender-neutral composite, and z -scores) with laboratory results. Significant associations were identified as 95% confidence intervals, not including zero. The results indicated that V̇ o2 peak ( r = 0.61, [0.08-0.84]), body fat percentage ( r = -0.4, [-0.72 to -0.06]), and relative peak power ( r = 0.38, [0.02-0.68]) were associated with the total ACFT composite score when partialled by sex. All laboratory tests, except the movement screening, showed meaningful associations with total ACFT z -scores and gender-neutral ACFT scores ( r > 0.54). However, most relationships were eliminated when partialled out by sex, which may be due to a low sample size of women. This suggests the current scoring structure utilized for men is representative of aerobic and anaerobic fitness parameters and may be able to discriminate performance levels.
