Objectives: We aimed to determine the injury patterns associated with training activities in elite South Korean taekwondo athletes training for the Olympic Games.
Methods: We collected data prospectively from 2007 to 2016 at the Korea National Training Center in Seoul, South Korea. A sports injury was defined as acute or chronic musculoskeletal signs and symptoms due to taekwondo activities during training sessions. Athletes were assessed by an on-site sports medicine specialist. The elite taekwondo athletes were stratified according to sex, weight class (flyweight, featherweight, welterweight and heavyweight), injury location (body region and site) and injury severity (mild or level I, requiring treatment for 1-3 days; moderate or level II, requiring treatment for 4-7 days; or severe or level III, requiring treatment for ≥8 days).
Results: Athlete exposure was 56 160 training sessions that took 249 600 hours. 1466 injuries were recorded in 283 athletes, with an average of 4.6 injuries per athlete annually. Of these, more than half (56%) were mild injuries, with most injuries occurring in the lower extremities (65.5%), followed by injuries to the trunk (16%), upper extremities (14%) and head and neck area (4%). Among these athletes, women had higher injury rates in the featherweight and welterweight categories (P≤0.0001), but there were no sex differences in other weight categories. In general, female athletes and male athletes experienced a comparable risk of injury (relative ratio: 1.55; 95% CI 0.89 to 2.68).
Conclusion: In elite South Korean taekwondo athletes, most injuries occur in the lower extremities and were graded as minor. Injury severity depended on weight class.
