Effects of a greater incentive to attack the head & face region on incidence of head kicks and concussions among male youth taekwondo competitors.
CONCLUSIONS: Although the incidence rates of HKs and concussions are considerably high, they are not increased compared with the results of pre-2009 studies. Therefore, the new competition rule relating to HKs did not appear to increase the incidence rates of HKs or concussions in our research participants. To prevent adverse effects related to repetitive HKs and concussions, continuous research is needed.
