초록

The study purpose was to investigate skill level differences on trunk, pelvis, and supporting leg kinematics in a Taekwondo roundhouse kick. 10 intermediate and nine expert male black-belt holders executed roundhouse kicks at a target. Orientation angles of the pelvis, trunk, and supporting -thigh, -shank, and -foot were obtained through a three-dimensional video motion analysis. Orientation angles at Start, Toeoff, Maximum Knee Flexion(MKF), Impact, Maximum angle(Max), and Minimum angle(Min) were compared between groups using independent t-tests(p<0.05). Significant differences between groups were found in the pelvis left lateral tilted position at MKF, Impact, and Min; significant differences were also found in the supporting hip joint flexed position at Start and Max, and abducted position at MKF. It was concluded that higher performers increased the hip joint flexion angle in the Push phase, decreased abduction angle at MKF, and decreased the pelvis left tilted angle in the Strike phase.
