The high incidence of football injuries emphasizes the importance of injury prevention. However, there is limited documentation of compliance with injury prevention programs in sports. The information of factors influencing compliance is insufficient, and the relationship between attitudes and compliance with prevention programs is not yet documented.


The aim of this investigation is to assess team and player compliance with a comprehensive warm-up program (The 11+) designed to reduce the risk of injuries in football, to examine the differences in injury risk among teams and players with different levels of compliance, and to assess attitudes towards injury prevention among coaches and their association with compliance and injury risk.



This study is part of a larger randomized controlled trial aimed to prevent injuries in youth female football players; The 11+.  More than 125 clubs with female players aged 14-16 yrs will be randomized to either an intervention or a control group. The intervention group will be introduced to The 11+ warm-up program throughout the 2007 football season. Compliance with the warm-up program, exposure in training and match, as well as injuries sustained, will be recorded prospectively.

At the end of the football season, all coaches participating with their teams in the intervention group will be interviewed to assess coaches´ attitudes, motivational factors and perceived barriers with conducting the warm-up program.


Results from this project will reveal important information about coaches attitudes towards injury prevention and to what degree compliance is correlated to injury risk. More detailed insights into coaches attitudes and acceptance of injury prevention strategies will contribute in the preparation of further intervention studies.
