BACKGROUND: Limited research has been done on head blows that may result in mild
traumatic brain injury in Taekwondo. The purpose of this study was to
investigate the fighting conditions under which blows to the head commonly take
place, with a view to determining the typical conditions under which injury may
occur. METHODS: EXPERIMENTAL DESIGN: videotape analysis (retrospective).
SETTING: the semi-final and final matches (a total of 48 matches) at the 14th
World Taekwondo Championships in 1999. PARTICIPANTS: 64 athletes (32 females and
32 males) who won elimination-round matches (out of 563 competitors), aged 15 to
38 years. MEASURES: frequency, mechanism of head blows, characteristics of
situations leading up to and following head blows, frequency of multiple
impacts. RESULTS: A total of 35 incidents of head blow occurred (365 blows per
1,000 athlete exposures). All of these head blows were associated with a direct
head or face contact and frequently involved: a closed sparring stance, shorter
athletes, axe or roundhouse type kicks, attacker's offensive kick, and
head-blow-receiver's offensive action with absence of a blocking skill.
CONCLUSIONS: To prevent possible brain injury resulting from direct head blows,
updated safety education, a complete understanding of concussion for athletes,
coaches, and referees, and a rule change in competition Taekwondo are
recommended.
