Military duties require immense cognitive-motor multitasks that may predispose soldiers to musculoskeletal injury. Most cognitive challenges performed in the research laboratory are not tactical athlete specific, limiting generalizability and transferability to in-field scenarios. The purpose of this study was to determine the impact of a cognitive-motor multitask (forward drop jump landing while simultaneously performing simulated shooting) on knee kinetics and kinematics. ⋯ Cognitive challenge induced knee landing biomechanics commonly associated with injury risk. Injury risk screening or return-to-training or duty assessments in military personnel might consider both baseline and cognitive conditions.

The Army Combat Fitness Test (ACFT) is a performance assessment used by the U.S. Army to assess a cadet's strength, endurance, and agility with a series of six events to ensure that cadets are combat ready. Heart rate variability (HRV) is an instrument that measures cardiac autonomic modulation and has been incorporated to predict the performance of athletes in daily training and competition since acute bouts of exercise alter HRV variables. ⋯ HRV was not a predictor of ACFT performance for individual events or overall ACFT. The SI presented predictive properties only for 2MR, with no other significant correlations between HRV variables with standing power throw and sprint drag carry. The SI ability to predict 2MR performance outcome via HRV is a promising tool to assess army cadet performance and recovery.

Transgender individuals have served openly in the U.S. Military since 2016. Official policies for transgender servicemembers continue to evolve, including approaches to physical fitness testing of transgender servicemembers. There is a paucity of scientific data regarding the effects of gender affirming hormone therapy (GAHT) on athletic performance for the past 24 months of treatment. Identification of expected trends in performance during and after gender transition is essential to allow for the development of appropriate military policy regarding when to assess servicemembers' fitness by standards of their affirmed gender. ⋯ In a sample of Air Force adult transgender patients, athletic performance measures demonstrate variable rates of change depending on the patients' affirmed gender and differ by physical fitness test component. Based on this study, transgender females should begin to be assessed by the female standard no later than 2 years after starting GAHT, while transgender males could be assessed by their affirmed standard no earlier than 3 years after initiating GAHT.

Musculoskeletal injuries (MSIs) are common among U.N. military personnel and cause a substantial toll, but little is known about the actual risks and changes of MSIs. The Chinese level II hospital (CHN L2H) was the highest-level hospital in the Western Sector of the U.N. Mission in South Sudan (UNMISS). This study reviewed and analyzed the MSIs managed by the CHN L2H in UNMISS. ⋯ MSIs are common diseases in the CHN L2H in the Western Sector of UNMISS. The universality and complexity of MSIs demonstrate the urgent need to improve prevention, treatment, and rehabilitation.

The Veterans Health Administration (VHA) is tasked with providing access to health care to veterans of military service. However, many eligible veterans have either not yet enrolled or underutilized VHA services. Further study of barriers to access before veterans enroll in VHA care is necessary to understand how to address this issue. The ChooseVA (née MyVA Access) initiative aims to achieve this mission to improve veterans' health care access. Although veteran outreach was not specifically addressed by the initiative, it is a critical component of improving veterans' access to health care. Findings from this multisite evaluation of ChooseVA implementation describe sites' efforts to improve VHA outreach and veterans' experiences with access. ⋯ Although efforts across VHA programs informed veterans about VHA services, our results suggest that both VHA staff and veterans agreed that missed opportunities exist. Gaps include veterans' lack of awareness or understanding of VHA benefits for which they qualify for. This can result in delayed access to care which may negatively impact veterans, including those separating from the military and vulnerable populations such as veterans who experience pregnancy or homelessness.
