title: Prevalence rate of chronic overuse pain in taekwondo athletes.
abstract: BACKGROUND
  The aim of this study was to estimate the prevalence of chronic overuse pain (COP) and to identify possible risk factors of COP in sport poomsae taekwondo.
  
  
  METHODS
  This is a cross-sectional survey. A total of 263 sport-poomsae competitors (112 females; 151 males; aged between 12-44 years), who competed at the 2014 sport poomsae taekwondo competition, participated in this study. The prevalence rate of COP and possible risk factors associated with COP were analyzed by using Chi-square tests and independent t-tests.
  
  
  RESULTS
  A total of 173 athletes reported that they experienced COP (65.8%; 95% confidence interval [CI]: 60.5-71.5). Female athletes showed a higher prevalence rate than their male counterparts (75.9% vs. 58.3%). Lower body (61.5%) and knee joints (26.4%) were the two primarily injured body part. A total of 101 athletes reported that they injured in the previous year. Among those, 81.2% were suffered from COP. The technique that caused pain most frequently was side-kick among females and front-kick among males. Prevalence rates of COP were significantly different by sex, education level, training hour, and a history of injury.
  
  
  CONCLUSIONS
  The prevalence of COP is high among sport poomsae taekwondo athletes. Competitors who are female, have a history of injury, and train for extended hours were more likely to experience COP. To identify other potential risk factors of COP in sport poomsae taekwondo, more research is needed to build upon the findings.
