Objective: The main objective of this study was to investigate the injury distribution in outstanding taekwondo athletes before their participation in national contests. Methods: Two hundred and fifty-four taekwondo athletes from senior high schools were participated in this study, and variables, including the pregame training, the injury distribution, the causes of injuries and the immediate treatments were investigated. Results: The results showed: (1) The training frequency was 7.2 times for males and 6.2 times for females per week; the averages training time was 2.56 hours and 2.4 hours for males and females respectively. (2) The incidence of injury for the pregame training was up to 88.98%, while 48.8% of athletes worried that the injuries would affect their performance in contest. (3) In case of pregame upper-limb-injuries, 26.7% occurred on the lower back; as the lower body, while 24.8% was taken place in insteps. In the type of injuries, contusion accounts for 49.6% among athletes. (4) According to our investigation, the main reason for injuries was the lack of warm-up, which accounts for 62.2%. Besides, 117 athletes accounting up to 46% claimed that intensive over-training before contests makes them feel discomfort mentally and physically. Whereas, 33.5% athletes assumed that their injuries could be caused by their immature technique, while training. (5) The results on immediate treatment to injury showed 34.6% of athletes obeyed their coaches' instructions and got trained continually. The main treatment method was the ice therapy, which was about 52.7%. Conclusion: This study reveals that the proportion of injured athletes, participating in taekwondo competitions was higher, and injured athletes would be anxious about their injuries that may affect the final results. It is suggested, during daily training programs, coaches should avoid over-training, and examine if the distribution of quality and quantity of training is proper. At the same time, coaches should frequently attend sports-injury courses or conferences, and encourage students to enrich their sports-injuries knowledge.
