title: An addendum to injury rates in Iranian taekwondo athletes; a prospective study.
abstract: OBJECTIVE
  The objective of this study was to compare the Iranian taekwondo-in statistically in terms of total injury rates to international counterparts as gleaned from the extant literature.
  
  
  METHODS
  The Iranian sample consisted of 204 male taekwondo-in participating in the national championship. The international sample included the participants in national and international tournaments. Validated standard questionnaires were employed at all tournaments to collect injury data that were always diagnosed by the respective tournament physicians. An injury was defined as any circumstance for which assistance was sought from the medical personnel. In addition to injury rates, 95% confidence intervals (CIs) around the rates were computed. To assess which group was at higher risk, odds ratios were calculated, including the 95%CIs.
  
  
  RESULTS
  Compared to Greek counterparts, the injury rate for the Iranian taekwondo-in was statistically significantly higher. The Iranians were also at a higher risk to incur an injury: OR = 11.2 (95%CI: 6.60-18.88, P<0.001, CLR = 2.86). When comparing the Iranian taekwondo-in to their colleagues competing at the 1999 World Championships, the former recorded a statistically significantly lower injury rate but the latter were not at a higher risk (OR = 0.61, 95%CI: 0.41-0.91, P=0.014, CLR = 2.20).
  
  
  CONCLUSIONS
  A statistical comparison of total injury rates in Iranian and international taekwondo-in revealed no difference between the two groups. However, what is of concern is that the total injury rate across taekwondo studies is significantly higher than those reported for American football.
