title: Non-participation in sports injury research: why football players choose not to be involved.
abstract: OBJECTIVE
  To ascertain the reasons behind players not participating in a sports safety research project.
  
  
  METHODS
  During the preseason, 10 Australian football clubs volunteered 23 teams to participate in a protective equipment randomised controlled trial, the Australian Football Injury Prevention Project (AFIPP). All players from these teams were invited to participate. Players who did not agree to participate in AFIPP were surveyed about their reasons for non-involvement.
  
  
  RESULTS
  110 football players (response rate 63.6%) completed the non-responder survey and cited the two main reasons behind non-involvement in the project as "I did not know about the project" (39.4%) and "I was not at training when the research team visited" (36.5%).
  
  
  CONCLUSIONS
  and implications: Preseason may not be the best time for maximal player recruitment in community based sports safety research. Enhanced communication between researchers and players at community level football clubs during the recruitment phase is likely to improve response rates.
