상단공격을 받은 태권도 선수들의 뇌손상 위험도 분석

The purposes of this study are to measure incidence rates of head kicks (HKs) and concussions and to analyse the possible risk factors of concussion among Olympic-style taekwondo during taekwondo competition in 2018. A prospective Cohort study design was used in this research. A total of 51 among 203 high school female athletes, who have received a valid HK from the opponent during bouts, were interviewed right after competition (mean age=17.76, SD=0.76). The χ2 -test and binary logistic regression were performed. In results, a total of 51 athletes were received one or more head kicks during competition. The incidence rates of HKs and concussion were 13.2 HKs (95% CI: 9.8 to 16.6) and 4.4 concussions (95% CI: 2.4 to 6.5) per 100 A-E, respectively. The χ2 -test showed that there is a significant difference between the athletes who have watched and who have not watched the HK from the opponent during sparring. Also, the test found a significant difference between the athletes who have used blocking skills and who have not used blocking skills when receiving HKs during sparring. The binary logistic regression showed that the athletes who have watched blowing a HK from the opponent during sparring experienced less concussions (odd ratio was 11.5, p<.01). There was no a memory function issue reported among 17 athletes with concussions. In conclusions, the incidence rates of HKs and concussions were not high. Only one factor found as a predictor for the concussion. To verify a precise incidence rate and risk factor of taekwondo related concussions, continuous research is needed.
