Objectives: to find out the pain prevalence in competitive karate practitioners derived from training and its relation to anthropometric and sports factors. Methods: prevalence study. A total of 56 karate practitioners completed a questionnaire at the end of their karate training. Results: the pain prevalence was 67.9%. The knee has been shown to be the most prevalence zone related to pain (31%) as well as related to instability subjective feeling (50%). There were significant statistical correlations between pain and age (p=0.04), Body Mass Index (p=0.045), belt level (p=0.017) and karate training frequency (p=0.011). Conclusions: the pain in competitive karate practitioners during training shows a high prevalence in the sample studied. There was a statistically significant correlation in pain in karate practitioners with higher body mass index, higher age, higher belt level and higher karate training frequency.
