title: Injuries and musculoskeletal complaints in referees--a complete survey in the top divisions of the swiss football league.
abstract: OBJECTIVE
  To analyze the extent and characteristics of injuries and musculoskeletal complaints in elite football referees and to analyze differences between match and assistant referees.
  
  
  METHODS
  Retrospective cohort study.
  
  
  METHODS
  Training camp organized by the Swiss Referees Association.
  
  
  METHODS
  All 71 referees of the 2 top divisions of the Swiss Football League (2005-2006 season).
  
  
  METHODS
  The referees (66 males and 5 females) completed a questionnaire on their personal characteristics, referee qualifications, time spent in training and matches, career history of injuries, and musculoskeletal complaints caused by training or refereeing and were subsequently interviewed about the location, type, circumstances, and consequences of reported injuries.
  
  
  METHODS
  Incidence of injuries, frequency of musculoskeletal complaints, type of injuries, and complaints.
  
  
  RESULTS
  A total of 41 injuries during the career were reported by 31 of 71 referees (44%). Injuries were incurred more frequently in training than during matches, and all injuries reported resulted in at least 2 weeks of absence from sport. About a quarter of the referees reported an injury, and almost 90% of the referees reported musculoskeletal complaints caused by refereeing during the preceding 12 months. In male referees, hamstring strains and ankle sprains were the most common injuries, and the hamstrings, knee, Achilles tendon, and calf were the most prevalent locations of musculoskeletal complaints. No significant difference in the incidence of injury or in the frequency of complaints was observed between match and assistant referees.
  
  
  CONCLUSIONS
  Future studies should be designed prospectively and should include a larger group of female referees. Regarding the incidence of injuries and frequency of musculoskeletal complaints related to refereeing, prevention programs for football referees should be developed, evaluated, and implemented.
