Abstract

INTRODUCTION: The cadets in the U.S. Army Reserve Officers' Training Corps (ROTC) consist of students from varied backgrounds. As part of collegiate ROTC programs, cadets must pass fitness tests and adhere to body composition standards in addition to completing their education. The previous fitness test of record was the Army Physical Fitness Test (APFT), but it was recently changed to the Army Combat Fitness Test (ACFT) to better test soldiers for combat capabilities. As part of the standardized scoring, the ACFT is no longer separated by sex or age as in the APFT, but rather by job duty. The purpose of this study was to characterize the modern ROTC cadet based on body composition measures and APFT and ACFT scores and then determine how those factors are related.
MATERIALS AND METHODS: We calculated body mass index (BMI), fat mass, fat-free mass (FFM), fat-free mass index (FFMI), and fat mass index (FMI) (n = 68, 42 males, 26 females). We used Pearson correlations to compare the scores to body composition assessments and Student's t-tests to determine if there were differences between sexes. We hypothesized that those with higher FFM and FFMI will have a higher passing rate on the ACFT and that males would perform better on the ACFT because of having more FFM.
RESULTS: We found that cadets, regardless of sex, were borderline overweight using BMI standards and that BMI did not correlate with any fitness tests. When comparing sexes, both males and females had high passing rates on the APFT, but females struggled to pass the ACFT mostly because of the leg tuck. We also found that ACFT scores were strongly correlated with FFM and FFMI, yet no body composition measures were correlated with APFT scores.
CONCLUSIONS: It is clear from our data that structured training programs and nutrition guidance are needed with an emphasis on changing body composition to increase lean mass and strength to increase the performance of ROTC cadets on the ACFT. © The Association of Military Surgeons of the United States 2021.
