군인 근골격계 부상 예방운동의 체계적 문헌고찰 및 메타 분석 = Systematic Review and Meta-analysis of Exercise for the Prevention of Musculoskeletal Injuries in Soldiers

다국어 초록 (Multilingual Abstract)

Purpose: This study aimed to conduct a systematic literature review and meta-analysis of the exercise intervention effects for the prevention of musculoskeletal injuries in military personnel.
Methods: Among studies that included military personnel as participants, we identified randomized controlled trials (RCTs) and cluster-RCT studies that used exercise interventions as a method for injury prevention. Exercise encompassed all types of physical activity, and the effect size was determined by the ratio of injuries between groups. Literature searches were conducted with search terms modified to ensure common inclusion of keywords such as “Soldier,” “Injury prevention,” and “Exercise.” For the analysis of potential factors, variables selected for group differentiation included gender, risk of bias, exercise volume, injury location, exercise type, and study design.
Results: Among a total of 8,598 search results, 10 papers were finally confirmed. The meta-analysis of all 10 papers showed that there was no statistically significant injury prevention effect, and significant heterogeneity was observed among the studies (incidence rate ratio, 0.82; 95% confidence interval, 0.62-1.09, I2=83%). Subgroup analysis revealed a significant 44% reduction in injuries in studies where exercise volume for injury prevention was relatively high. However, no significant injury prevention effects were observed in other potential factors between groups. Conclusion: The results of this study suggest that the effectiveness of injury prevention exercises in military settings was not statistically significant. However, through the analysis of potential factors, it was confirmed that increasing the time spent on injury prevention exercises may have a preventive effect on injuries.
