Approximately 7.8 million high school students participate in athletics annually and although athletic participation comes with many benefits, it also comes with an inherent risk of lower extremity (LE) musculoskeletal (MSK) injury. Effectively identifying individuals at greatest risk of injury first requires an accurate understanding of injury risk. Despite the breadth of research, current injury risk assessment models are inadequate and no gold standard exists for effectively identifying risk of injury in physically active populations. Most research fails to target multiple risk factors and, instead, often focuses on how one specific risk factor alters injury risk. Additionally, research has not examined how injury risk is altered by relationships among risk factors. These gaps in knowledge have formed an understanding of injury risk that does not reflect a multi-factorial model where factors influence risk through a combination of direct, indirect and moderated effects. Therefore, the purpose of this research was to assess the complex multifactorial nature of LE MSK injury risk in adolescent athletes.
Aim 1 established similarities and differences in epidemiology of injury in boys' and girls' high school soccer and basketball using a national injury surveillance system. The results of this aim indicated that injury rates are greater in soccer than basketball, and greater in competitions than practices, regardless of sex. The most common injuries were similar between sports, suggesting both sports should emphasize preventing sprains and strains affecting the ankle and knee, specifically those resulting from player contact and noncontact mechanisms. Additional efforts are also needed to prevent hip and thigh/upper leg injuries in soccer.
Aim 2 evaluated direct and indirect effects of functional performance asymmetries, as well as drop landing mechanics, on injury in 2,645 high school soccer and basketball players. Results from this aim indicate that ankle do (open full item for complete abstract)
