Preventing military sexual assault (SA) is a DoD priority. Building prevention capacity could strengthen the impact of prevention programs and improve outcomes. Capacity was conceptualized as implementation knowledge and skills using the Getting To Outcomes (GTO) process and organizational-level capacities using the Prevention Evaluation Framework, a framework that applies best practices in prevention and implementation science to prevention at the program and organizational level. The present study assesses implementation knowledge and skills currently possessed by SA prevention personnel in one U.S. Army installation with the goal of identifying preexisting proficiencies and potential gaps. The study uses the Prevention Evaluation Framework organizational-level domains to identify organizational capacities that could be improved. ⋯ The GTO-specific knowledge and skills of SA prevention personnel at one U.S. Army installation revealed proficiencies and gaps in organizational capacities influencing the prevention mission. Findings indicate that GTO support could be useful for improving the quality of program activities. However, results also indicate that GTO support would be more effective if they were paired with sufficient prevention infrastructure at the organizational level.

Pregnancy has a profound impact on physical fitness, and delivery does not allow for rapid return to peak performance levels as physiologic changes can persist for greater than 1 year postpartum. Multiple studies across all military services have documented decrements in physical performance with pregnancy among women. The purpose of this study was to determine the impact of serial pregnancies on physical fitness and body composition in a cohort of Army women. We hypothesized that a second pregnancy would be associated with increasing decrements in physical fitness in active duty soldiers beyond that seen following a first delivery. ⋯ The present study is the first to analyze the association of serial pregnancies on physical fitness utilizing a validated physical fitness test, and the results suggest that a second pregnancy is associated with progressive worsening of performance. This study is limited by the small sample size, and future studies could further elucidate the degree to which serial pregnancies affect physical fitness.

Low back pain (LBP) is highly prevalent after lower limb amputation (LLA) and contributes to substantial reductions in quality of life and function. Towards understanding pathophysiological mechanisms underlying LBP after LLA, this article compares lumbar spine pathologies and muscle morphologies between individuals with LBP, with and without LLA. ⋯ Despite similar lumbar muscle size, those with unilateral LLA may be predisposed to progress to symptomatic spondylolisthesis and intramuscular fat. Surgical and/or rehabilitation interventions may mitigate long-term effects of diminished spinal health, decrease LBP-related disability, and improve function for individuals with LLA.

The purpose of this study was to investigate the effect of environmental conditions on body composition, upper body power, and lower body power throughout a ∼4-week military mountain training exercise. We hypothesized that countermovement jump and ballistic push-up performance would decrease as a result of extended mountain field training and that winter (cold) conditions would result in greater decrements compared to fall (temperate) conditions. We also expected to observe a strong positive correlation between changes in performance and changes in skeletal muscle mass. Finally, we expected acute changes in performance upon altitude exposure. ⋯ The results of our study suggest that explosive movements are negatively affected by extended military training, seemingly independent of environmental training conditions or temperature. Planning and execution of military training should account for the likelihood that warfighter physical power will decline and may not return to pretraining levels within the month following the training event. It may also be advised to consider targeted exercises to aid in recovery of muscular strength and power. Future work should consider additional factors that likely influenced the decrease in physical performance that occurs during extended military training, such as nutrition, sleep, and psychological and cognitive stresses.
