Objective We attempted to analyze the characteristics of lower-extremity
injuries that occur during training based on the sex and weight class of elite
taekwondo (TKD) athletes and the effect of pain scores on the return to sports
periods (RTSP). Methods and Methods: We included 198 elite TKD athletes who
participated in January–December 2023 and were trained in Korea. Injury
incidence rates (IIR) were expressed as Poisson rates with 95% confidence
intervals per 1,000 h of training. One-way analysis of variance was conducted to
determine the pain score and RTSP according to sex, weight, and injury type. In
addition, we performed simple linear regression to determine the effects of pain
score on the RTSP.
Results The lower-extremities IIR was 2.45 injuries per 1000 training
hours, including 0.77 contact and 1.68 non-contact injuries. The IIR was lower
in male than in female athletes (p<0.001), the most common injuries occurred
in the ankle (0.78) and knee(0.53). In addition, the ligament (0.99) and muscle
(0.70) were the most common injury types. All athletes demonstrated significant
differences in pain scores (p<0.001) and RTSP (p<0.001) based on the
injury type. In addition, we observed a significant difference between the pain
score (p<0.001) and RTSP (p=0.004) based on sex. For every 1-point increase
in pain score, all athletes had a 1.43-day increase in RTSP.
Conclusion These results can be used as data to develop injury prevention
programs for TKD athletes and to determine their RTSP.
