Efficacy of Army Combat Fitness Test 12-Week Virtual Exercise Program.

INTRODUCTION
The Army Combat Fitness Test (ACFT) is the fitness assessment used by the Army launched in April of 2022. The ACFT consists of six physically demanding motor movements that parallel to the stressors experienced by the modern-day combat soldier. The aim of this study is to determine the efficacy of a 12-week virtual exercise program on the individual and their overall ACFT scores.


MATERIALS AND METHODS
Thirteen soldiers from the Army National Guard (age = 29.8 ± 6.2 years; height = 175.7 ± 6.1 cm; service experience ≥ 18 months to 18 years) volunteered to complete three sessions. In session 1, baseline height, body mass, body composition, and ACFT scores were collected. Session 2 consisted of a suspension trainer (ST) tutorial in which all participants familiarized themselves with the set-up and utilization of the suspension training tool kit. Upon completion of session 2, a TRX Elite ACFT Kit containing one suspension trainer, four resistance bands, and the 12-week virtual exercise training program available via iphone operating system and Android were given to all participants. In session 3, post-assessments of body mass, body composition, and ACFT scores were collected. Data were statistically analyzed using a paired-sample t-test with a Bonferroni correction (P < .00065) to adjust for multiple comparisons.


RESULTS
There were no significant changes in mean body mass (83.8 ± 16.5 kg vs. 83.9 ± 16.6 kg; P = .752); however, there was a significant reduction in mean percentage body fat (19.5 ± 6.4% vs. 18.3 ± 6.5%; P < .0001). Mean scores from four of the six individual ACFT assessments, specifically, deadlift, standing power throw, hand-release push-ups, and sprint-drag-carry, displayed improvements, but did not attain statistical significance. The overall mean ACFT scores displayed significant improvements (319.4 ± 39.9 vs. 390.4 ± 68.5; P < .0001).


CONCLUSIONS
The TRX Elite ACFT Kit which includes one suspension trainer, four varying resistance bands, and on-demand access to a stepwise 12-week virtual exercise program was deemed effective by increasing the overall mean ACFT scores among participants. From a practitioner's perspective, the TRX Elite ACFT Kit should be widely distributed to all Army units and recruiting commands to provide vital assistance for recruits and soldiers to train and prepare for the ACFT. Moreover, given the ease and portability of the TRX Elite ACFT Kit, recruits and soldiers will be able to effectively train anytime, anywhere.
