Description
Summary:Military personnel confront heightened risks of musculoskeletal injuries (MSIs) because of the demanding nature of their duties, contributing to restricted active duty and financial burdens. Although preventable factors like training and physical fitness influence some injuries, understanding the enduring effects of previous MSIs on physical fitness in military personnel remains a critical gap. This study aimed to systematically review and meta-analyze this impact. In accordance with PRISMA guidelines, a systematic review with meta-analysis was conducted, focusing on military personnel with and without a history of MSIs. Physical fitness components were assessed via observational studies, with isokinetic peak torque values as primary metrics. Quality assessments utilized the NIH Quality Assessment Tool and GRADE framework. Out of 36 papers, 6 met inclusion criteria, with 4 included in the meta-analysis. Across 1,267 participants, individuals with prior MSIs exhibited a significant reduction in the pooled effect size for isokinetic peak muscle force, with d+ = -0.25 (95% CI: -0.36 to -0.13), notably affecting knee and shoulder regions. These findings underscore the pervasive impact of MSIs on military personnel's physical performance, necessitating targeted interventions. Military personnel with prior MSIs exhibit enduring deficits in isokinetic peak muscle force, particularly in knee and shoulder regions. However, evidence on the impact of previous injuries on other physical fitness components remains limited. Further research is crucial to understanding the multifaceted impact of MSIs on diverse aspects of physical performance, informing comprehensive injury prevention strategies and optimizing performance outcomes among military personnel.
