초록

The purpose of this study was to compare joint angle, angular velocity, and EMG activity of wrist during 'Joa-u-chigi' according to skill level and style of ‘Seungmu’. Ten skilled dancers and ten collegiate students majoring in Korean dance participated in the study. Dependent variables were measured and compared according to skill level as well as between skilled dances of both styles. Main results were as follows: 1) No significant difference was found in angular velocity and muscle activity between skilled and unskilled of 'Mae-Bang Lee' style. However, the timing of the snap was different according to skill level. 2) Angular velocity and muscle activity was higher in skilled than unskilled of 'Young-Sook Han' style. 3) The range of changes in angle of wrist during 'Joa-u-chigi' was similar between 'Mae-Bang Lee' style and 'Young-Sook Han' style; however, the timing when the changes occurred was different according to the dance style. Angular velocity and muscle activity during 'Joa-u-chigi' were higher in skilled of 'Young-Sook Han' style than skilled of 'Mae-Bang Lee' style. It was concluded that the movement of wrist during 'Joa-u-chigi' was performed with better timing as well as in smoother and stronger fashion in skilled than unskilled in both styles.
