한국무용과 발레 무용수의 보행 동작에 대한 운동학적 변인 비교 = A Kinematical Comparison of the Gait Patterns between the Korean Traditional and Ballet Dancers

다국어 초록 (Multilingual Abstract)

The purpose of this study was to analyze the gait patterns of kinematics in Korean traditional and ballet dancers. 12 dancers (ballet dancers: 6, Korean Traditional dancers: 6) were participated in this study. Four cameras were used to get the kinematic data using DLT (Direct Linear Transformation) method. Gait parameters (foot angle, step width, step length and stride), displacement of Center Of Mass in the superior/inferior and left/right direction, and the angles of lower limb were analyzed. The following conclusions were drawn : 1. Gait parameters : Foot angle, step width, step length and stride in ballet dancers were significantly larger than those in Korean Traditional dancers. The ratio of the stance and swing phase in Korean Traditional dancer showed similar result in accordance with the previous study. However, ballet dancers showed short stance phase and large swing phase. 2. Center Of Mass(COM) : COM of superior/inferior displacement in Korean Traditional dancers was smaller than that in ballet. This was explained that COM of superior/inferior displacement in midstance of the right and left foot were small. COM in Korean Traditional dancer was changed from right direction to left direction between the time of the left foot heel-strike and right foot take-off whereas ballet showed that COM was changed from right to left. 3. Angles : Korean Traditional dancers showed greater hip angle than ballet. However, ballet showed greater hip rotational angle in transverse plane than Korean Traditional dancers.
