Musculoskeletal injuries continue to reduce the operational readiness of military organizations. Knowing and understanding the key risk factors that could be used to predict high risk personnel is vital to targeting injury prevention measures. Despite the abundance of research studies aiming to identify risk factors for injury, there is very little consensus as to what are the most effective outcome metrics to assess.
The purpose of the study was to systematically review the association between muscular endurance and muscular strength on musculoskeletal injury risk in military populations.
A comprehensive review of the literature was undertaken that spanned all research between 1970 through 2015. Of 4,229 studies identified in the initial database search, only 45 met the strict methodological criteria, including assessment of the study design and statistical analysis.
Isometric strength was assessed in 9 of the 45 studies with medium to high associations across the studies.
Lower hip external rotation strength, lower hip adduction and abduction strength, lower isometric knee flexion strength, and lower back extensor strength were all associated with higher risk of musculoskeletal injury compared to having higher strength. Thus, there appears to be a protective effect of strength on musculoskeletal injury risk in collegiate, professional athlete, and military populations.
VALD’s ForceFrame isometric strength testing system provides a reliable way to measure absolute strength and strength asymmetries across a range of muscle groups, including hip and knee. Quickly identify personnel who have lower strength and may be at higher risk of injury than stronger counterparts.
Quantify asymmetries in your population and easily flag high-risk individuals who require specialized physical training with VALD.
