Anthropomorphic and Physical Fitness Characteristics of United States Air Force Basic Military Training: Special Warfare Versus Nonspecial Warfare Recruits, Fiscal Year 2019-2023.

INTRODUCTION: Each year, thousands of individuals enlist in the Department of the Air Force (DAF), with some seeking to become DAF Special Warfare (SW) candidates. This study aimed to compare the anthropomorphic and physical fitness characteristics between these groups during fiscal years (FYs) 2019-2023. METHODS:  The sample includes male candidates below the age of 30 who attended the DAF basic military training (BMT) from FY2019 to 2023 (N = 119,415). Initial physical fitness testing was conducted during week 1 of BMT. Physical fitness results, height, weight, and body mass index (BMI) were compared between the two cohorts. A two-way analysis of variance was performed to analyze the effects of group (SW and non-SW) and FY on mean anthropomorphic and physical fitness test variables. Dependent variables were evaluated for homogeneity of variance using Levene's test and for normality using the Shapiro-Wilk test. The Tukey-Kramer test was employed for post hoc analyses with a threshold for statistical significance of α < 0.05. RESULTS:  The cohort of SW recruits displayed superior physical fitness results across all FYs (p < 0.001) with the exception of FY2021. They were significantly taller and heavier, and had a higher BMI when compared to non-SW DAF BMT recruits (p < 0.001). Mean values for maximum push-ups and sit-ups for SW recruits were significantly lower in FY2021 (p < 0.001) and not significantly different from non-SW recruits. Additionally, run times for both SW- and non-SW-bound recruits during FY2022 and FY2023 were significantly slower than previous years. CONCLUSIONS:  These findings can be used to establish a baseline for anthropometric and physical fitness profiles of incoming SW and non-SW DAF BMT recruits that may inform clinicians, human performance professionals, and military training leaders with information necessary to guide future research and physical fitness policy.

Running Gait Training Improves Outcomes at United States Air Force Basic Military Training.

INTRODUCTION: The aim is to investigate the impact of large-group, motor learning-based running gait training on injury risk in United States Air Force (USAF) Basic Military Training (BMT). DESIGN: A prospective quasi-experimental program evaluation is used. MATERIALS AND METHODS: Medical providers taught running gait form to groups of trainees in the first week of training of BMT from August 2020 to March 2021. The main outcome measures included risk ratio of reported injuries, removal from training because of injury, and separation from service because of injury. RESULTS: Of BMT trainees, 2,205 underwent group, motor learning-based running gait training; this was compared with two intake groups (nA = 3,941 and nB = 2,041) who were only given introductions to sports medicine staff in a classroom setting. Reported pain complaints increased (χ2 = 27.4A and 20.83B, P < .001). Risk ratios for more severe injuries necessitating time out of training or separation from USAF were reduced, although these were statistically not significant (13%, P = .48 and 22%, P = .29, respectively). Leadership implemented gait training across BMT, and data from the following 8 weeks of intake (n = 6,223) demonstrated similar trends in increases in patient reports of pain (χ2 = 67.25, P < .001) but significantly reduced risk ratios of removal from training (32%, χ2 = 16.35, P < .001) or separation (32%, χ2 = 12.54, P < .001). CONCLUSIONS: While not previously shown to mitigate injury, large-group, running gait training was associated with a significant reduction in injury severity defined by training delays and separation from service in USAF BMT.

Diabetes ROADMAP: Teaching Guideline Use, Communication, and Documentation When Delivering the Diagnosis of Diabetes.

Introduction: Most interventions to date regarding breaking bad news focus on late-stage disease or disclosing a cancer diagnosis. Little attention has been given to delivery of chronic metabolic disease diagnoses such as prediabetes/type 2 diabetes. Methods: Informed by the American Diabetes Association standards of care and formative research conducted by our research team, we developed this curriculum through the six-step approach to curriculum development. The curriculum consists of a 2- or 3-hour intervention that teaches medical decision-making, interpersonal communication, and clinical documentation in the context of prediabetes and type 2 diabetes followed by role-play and clinical practice. Results: Across three cohorts, 53 clinicians completed the curriculum. Across the three iterations, learners rated the curricular intervention as worthwhile and delivered at an appropriate level. In a community hospital setting, learners scored significantly higher on a knowledge check than did a control group of six clinicians (p < .001). Learners in the community hospital also indicated high response efficacy and self-efficacy. At the academic medical center, simulated patients indicated high measures on the Diabetes Health Threat Communication Questionnaire. Discussion: The moment of diagnosis presents a key opportunity to affect patients' perceptions of the disease. This curriculum guides clinicians in making the most of diagnosis delivery. Pairing of qualitative, patient-centered research alongside the iterative curriculum design process allows the curriculum to be adaptable and scalable to multiple settings and learner types.

Femoroacetabular Impingement Syndrome.

Femoroacetabular impingement (FAI) syndrome is one of the most rapidly evolving etiologies of hip pain. The 2016 Warwick Agreement consensus statement defined FAI syndrome as a triad of symptoms, signs, and radiographic findings. Cam morphology is more likely in athletes and is associated with repetitive hip loading in maximal flexion during adolescence. Much less is known about the development of pincer morphology. Physical therapy improves pain and function, justifying a trial before pursuing surgery. Musculoskeletal injections are utilized for FAI syndrome, but the evidence is limited. Arthroscopic surgery for FAI syndrome can correct the morphological changes and address the underlying soft tissue injuries. Recent studies evaluated reliable indicators of surgical outcomes, the most reliable of which is the presurgical presence of osteoarthritis. Recent studies demonstrate the efficacy of surgery, but with the risk of complication and no guarantee of a return to the same level of sport.

Optimizing Health, Wellness, and Performance of the Tactical Athlete.

Tactical athletes are individuals in service occupations with significant physical fitness and performance requirements such as law enforcement, firefighters, emergency responders, and military service members. Tactical athletes also may have specific administrative requirements related to documenting physical injuries. Musculoskeletal injuries are a large burden on the tactical athlete population, with incident rates varying based on the specific profession. Chronic exertional compartment syndrome (CECS) is difficult to manage in the tactical athlete population due to their limited ability to reduce impact activities and poor surgical outcomes. Botulinum neurotoxin-A and gait retraining show promise as alternative treatments for CECS. Heat injuries are frequent in the tactical athlete populations, and a graduated return to play process helps to prevent morbidity. Management of musculoskeletal injuries in tactical athletes requires consideration of operational schedules and adequate reconditioning, in addition to traditional injury evaluation.

Spine Conditions: Lumbar Spinal Stenosis.

Lumbar spinal stenosis (LSS) is a frequent cause of chronic low back and lower extremity pain in older patients. Symptomatic LSS typically is described as neurogenic claudication consisting of pain, weakness, numbness, and/or fatigue arising in the back and radiating into the buttock, thigh, or lower leg. The diagnosis is complicated by lack of reliable clinical or x-ray criteria. North American Spine Society guidelines recommend magnetic resonance imaging study without contrast to confirm anatomic narrowing of the spinal canal or nerve root impingement. Conservative management options include exercise and drug therapy. Epidural injections can be considered for temporary symptom management. No studies show greater effectiveness of surgical intervention over conservative management in patients with mild to moderate symptoms. Progressive symptoms, emergence of frank neurologic deficit, or findings consistent with cauda equina syndrome are indications to pursue surgical evaluation. Decompression surgery without fusion typically is recommended in the absence of spondylolisthesis or other spinal instability. Active rehabilitation is likely more effective than usual care for improvement in functional status within 12 months postoperatively without adverse events. Approximately one-third to one-half of patients with mild to moderate LSS symptoms may have a favorable prognosis.
