The U.S. military commonly uses body composition as an indicator of a soldier's potential to meet the physical demands required of their occupation. The purpose of this study was to determine whether significant relationships existed between select body composition variables and Army Combat Fitness Test (ACFT) performance among a cohort of university Army Reserve Officers' Training Corps (ROTC) cadets. Twenty-six male (20.4 ± 1.6 years, 81.8 ± 8.5 kg, 178.3 ± 7.8 cm) and 12 female (19.9 ± 1.4 years, 64.2 ± 6.7 kg, 161.9 ± 4.9 cm) cadets voluntarily participated in this study. Body composition was measured using bioelectrical impedance analysis, and ACFT event scores were recorded by the cadre using the U.S. Army standard protocol and provided to the investigators. Pearson's correlations were used to identify relationships between body composition variables and ACFT event performance with an alpha level of p ≤ 0.05. Moderate to strong relationships were observed between total body water, dry lean mass, lean body mass, skeletal muscle mass, body fat mass (FM), and body fat percentage and all event scores for the sample as a whole. Body mass index showed weak to moderate significant positive relationships with hand-release push-up and maximum hexagonal bar deadlift in the sample as a whole. No relationships were observed in the men of this sample. All body composition variables showed moderate, nonsignificant relationships with at least 1 ACFT event within the women of this sample. Considering the findings of this study, a multitude of variables could be useful to assess ROTC cadets as predictors for ACFT performance. Reserve Officers' Training Corps programs should emphasize attaining and maintaining functional lean mass, whereas reducing nonfunctional body mass (i.e., excess FM) among cadets to enhance health and performance across the occupational life span.

The purpose of this study was to determine the relationships between body composition measures and Army Physical Fitness Test (APFT) performance between male and female Reserve Officers' Training Corps (ROTC) cadets prior to enlistment. Retrospective APFT test performance and body composition data were provided for 57 male and 17 female university ROTC cadets. Descriptive statistics were derived for all variables and separated by sex. A MANOVA model was used to determine differences between sexes in all anthropometric and fitness variables. A Pearson's moment correlation was used to determine significant relationships between body composition and APFT measures separated by sex. Significant differences between male and female cadets for height, body mass, body fat percentage, and APFT events were found (p = 0.001-0.03). No significant differences were found between sexes for BMI (p = 0.887). Additionally, no significant relationships between anthropometric measures and fitness performance were observed among male or female cadets. [ABSTRACT FROM AUTHOR]

This study investigated traditional training (TT) versus ability-based training (ABT) in custody assistant recruits. Retrospective analysis was conducted on two recruit classes who completed an 8-week academy. The TT group (18 males, 13 females) followed a physical training model where recruits completed the same exercises with the same intensity; the ABT group (17 males, 12 females) had exercises tailored towards their ability. Pre- and post-academy, recruits were assessed in: body mass; body fat percentage (BF%); resting heart rate (RHR); blood pressure (BP); waist circumference (WC); waist-to-hip ratio (WHR); grip strength; push-ups; sit-ups; YMCA step test recovery HR; 201-m run; and 2.4-km run. Independent samples t-tests evaluated between-class pre-test differences, with significance set at p = 0.05. Paired samples t-tests (p = 0.05) detected within-group training changes. Change scores were calculated for each variable; independent samples t-tests (p = 0.05) compared change scores between groups. The TT group had lower BF%, BP, and WC; and were superior in sit-ups and the 2.4-km run before training. After academy, the TT recruits improved WHR, grip strength, recovery HR, 201-m run, and 2.4-km run, but increased diastolic BP. The ABT recruits decreased BF%, RHR, and WC, and improved push-ups, sit-ups, recovery HR, 201-m run, and the 2.4-km run. ABT recruits had greater positive changes in BF%, RHR, diastolic BP, and sit-ups. TT and ABT recruits generally experienced favorable fitness changes; the degree of positive change tended to be greater for ABT recruits for select tests. Coupled with the diastolic BP increase for TT recruits, this may provide evidence for ABT. [ABSTRACT FROM AUTHOR]
