Abstract

Purpose
This study aimed to analyze the profiles and mechanisms of injuries using online injury surveillance system (OISS) with match video files at 2017 World Taekowndo Championship (WTC) athletes.
Methods
This study design was a prospective epidemiological study with video analysis. All injuries were recorded during the 2017 WTC using the OISS developed by the International Olympic Committee. A total of 971 athletes who participated in the 2017 WTC were enrolled. Each injury was recorded retrospectively by three cameras surrounding each court. Injury profiles and mechanisms were calculated as; percent injury rate, injury rate/100 athlete-exposures, injury location, type, and mechanism via the injury surveillance system and video analysis form.
Results
There were 74 injuries, which corresponded to an overall incidence of 13.5 injuries (95% confidence interval, 11.2–15.8) per 100 athletes. The face (27.0%), hand/finger (23.0%), knee (14.9%), and ankle (10.8%) were most frequently injured parts. Contusions (37.8%), fracture and ligament sprains (20.3%) were the most frequently injury types. The main mechanism for contact injury is while attacking with the roundhouse kick (66.2%), or not used block (81.1%). There were also noncontact injuries (24.3%).
Conclusion
The incidence of injuries to the face, hand/fingers, knee, and ankle was relatively high. To prevent contact injuries, protective headgear and better shin guards and hand protectors need to be developed. As for the noncontact injuries, we recommend hamstring strengthening exercises, and neuromuscular training to strengthen the tendons and ligaments protecting the ankle and knee joints.
