The estimated cost to the Army for lower extremity fractures in 2017 was approximately $116 million. Direct medical expenses totaled $24 million, and indirect medical costs totaled $92 million ($900 thousand lost duty; $91 million limited duty). Foot and toe fractures, along with lower leg and ankle fractures accounted for the majority of soldiers' initial visits for care (n=4,482; 91.

The goals of this project were to quantify medical problems among a population of Military Working Dogs (MWDs) and analyze factors associated with common medical conditions. Medical conditions recorded in veterinary Master Problem List (MPL) entries for 774 young, non-deployed, active MWDs were categorized and combined with demographic information to analyze risk factors. Most dogs were male (74%), German Shepherd (39%) or Belgian Malinois (31%) breeds, certified in Explosive Detection (60%), and had a dark coat color (83%).

Introduction: Adverse effects of cigarette smoking on physical performance are well studied. Because of the recent rise in popularity of vaping, it is important to evaluate its effect on fitness both independently and in conjunction with traditional cigarette use.

Methods: This was a secondary analysis performed in 2018 on data collected from U.

Background: Musculoskeletal injuries (MSKIs) are common in military trainees and present a considerable threat to occupational fitness, deployability, and overall military readiness. Despite the negative effects of MSKIs on military readiness, comprehensive evaluations of the key known and possible risk factors for MSKIs are lacking. The U.

Background: Self-reported injury data are frequently used in epidemiologic investigations. These data provide useful information about the activities and mechanisms of injuries because injury cause-coding is often not required for outpatient medical visits.

Objectives: The purpose of this evaluation is to determine the accuracy of self-reported military injuries when compared to injuries in outpatient medical records.

Introduction: The purpose of this investigation was to examine changes over time in the physical fitness of the United States (US) Army infantry. A systematic review was conducted to identify and analyze articles and databases that reported on physical characteristics (height, weight, and body mass index) and/or Army Physical Fitness Test (APFT) scores of male infantrymen or men in infantry units.

Materials And Methods: The National Library of Medicine's PubMed and the Defense Technical Information Center were searched using specific keywords.

Objectives: Road marching is an important physical training activity that prepares soldiers for a common occupational task. Continued exploration of risk factors for road marching-related injuries is needed. This analysis has assessed the association between modifiable characteristics of physical training and injury risk.

Objectives: Army body composition standards are based upon validated criteria; however, certain field-expedient methodologies (e.g., weight-for-height, body mass index [BMI]) may disqualify individuals from service who may otherwise excel on physical performance and military-relevant tasks.

Article Synopsis
  • The study aimed to analyze how physical training and fitness levels affect the risk of running-related injuries (RRIs) in physically active young men.
  • Data from over 4,000 soldiers was collected using surveys focusing on personal characteristics, physical training, and injury history, revealing a 14% incidence of running injuries.
  • Results showed that younger age, lower BMI, increased personal training running distance, better aerobic endurance, and regular resistance training significantly lowered the risk of injuries, suggesting personalized training could help prevent RRIs.

: Physically demanding occupations (ie, military, firefighter, law enforcement) often use fitness tests for job selection or retention. Despite numerous individual studies, the relationship of these tests to job performance is not always clear. : This review examined the relationship by aggregating previously reported correlations between different fitness tests and common occupational tasks.

Background: The Functional Movement Screen (FMS) is a series of 7 tests used to assess the injury risk in active populations.

Purpose: To determine the association of the FMS with the injury risk, assess predictive values, and identify optimal cut points using 3 injury types.

Study Design: Cohort study; Level of evidence, 2.

The Functional Movement Screen (FMS) is a tool intended to evaluate limitations or asymmetries of movement to detect individuals at risk for exercise- and sports-related injury. The purpose was to determine the association and predictive value of specific FMS tests with injury risk in physically active men. Soldiers aged 18-57 years completed the FMS (n = 2,476).

Background: Low vitamin D status increases the risk of stress fractures. As ultraviolet (UV) light is required for vitamin D synthesis, low UV light availability is thought to increase the risk of vitamin D insufficiency and poor bone health. The purpose of this investigation was to determine if individuals with low UV intensity at their home of record (HOR) or those with darker complexions are at increased risk of developing stress fractures and lower limb fractures during U.

Background: Footwear characteristics can influence, fatigue, comfort, injuries and energy cost. Members of the United States Army Band have hundreds of performances a year and these performances often include prolonged standing and marching in footwear.

Objective: The purposes of this paper are to: (1) determine injury rates before and after wearing a shoe with presumed greater cushioning and ventilation among US Army Band members, and (2) identify risk factors associated with foot pain/discomfort.

Introduction: Military parachuting has been shown to result in injuries. This investigation systematically reviewed studies examining the influence of the parachute ankle brace (PAB) on injuries during military parachuting and performed a cost-effectiveness analysis.

Evidence Acquisition: Parachute ankle brace studies were obtained from seven databases, personal contacts, and other sources.

Background: This paper reports on a systematic review of the literature on the post-conflict injury-related mortality of service members who deployed to conflict zones.

Methods: Literature databases, reference lists of articles, agencies, investigators, and other sources were examined to find studies comparing injury-related mortality of military veterans who had served in conflict zones with that of contemporary veterans who had not served in conflict zones. Injury-related mortality was defined as a cause of death indicated by International Classification of Diseases E-codes E800 to E999 (external causes) or subgroupings within this range of codes.

Popular running magazines and running shoe companies suggest that imprints of the bottom of the feet (plantar shape) can be used as an indication of the height of the medial longitudinal foot arch and that this can be used to select individually appropriate types of running shoes. This study examined whether or not this selection technique influenced injury risk during United States Army Basic Combat Training (BCT). After foot examinations, BCT recruits in an experimental group (E: n = 1,079 men and 451 women) selected motion control, stability, or cushioned shoes for plantar shapes judged to represent low, medium, or high foot arches, respectively.
