External Stressors Prior to Traumatic Knee Injury in Youth Athletes.

The aim of this study is to evaluate different aspects of mental stress aspects and its role as a potential risk factor for traumatic knee injury in youth athletes. Approximately 300 athletes (age 16-19) 50% women) who are involved in high risk sports (soccer, handball and floorball) will be included. The athletes will record his/hers traumatic knee injury together with information about training regimes and some details on injury mechanism on a web-based form. The form also includes questions about mental stressors, such as club exchange, changed game system in addition to conflict within and outside the family, etc, prior to injury.

The present study will contribute new knowledge on levels of muscle function and different aspects of mental stress factors that may be related to traumatic knee injury in young athletes.
