Bioelectrical impedance analysis (BIA) is a non‐invasive, user‐friendly, inexpensive tool often used to estimate body composition changes in response to exercise training paradigms, dietary interventions, aging, and disease (Lukaski et al., PhA in the human body typically ranges from 1° to 12° (Sardinha & Rosa, Optimization of physical fitness, including muscular strength, power, and aerobic capacity, is an integral component of Warfighter training, as sustained, multi‐stressor military operations comprised of high energy expenditures, inadequate energy intake, and sleep deprivation typically degrade muscle mass and physical performance (Lieberman et al., Despite the potential for PhA to elucidate the underlying causes of performance decline, previous research using this metric of muscle quality has been limited to examining relationships between PhA and physical performance in cross‐sectional studies (Fukuoka et al.,
