The purpose of this study is to compare ground reaction force of “Nakhwayusu” movement of Korean Dance “Cheoyoung-mu”. The experiment is conducted with 5 skilled dancers and 5 unskilled dancers. And, according to the experiment results. following conclusions are acquired. First, although no significant difference is found between the skilled and unskilled dancers on duration time for “Nakhwayusu” movement, in P1, P2, P4 and P5, the skilled dancers are found to be slower while being faster in P3. Second, the Fx of “Nakhwayusu” movement, the GRF show significant differences in E3 and E6 (p<.05): The power implemented at the left for the skilled dancers and at the right for the unskilled dancers in E3. And, E6, the skilled dancers powers at their left sides while little power found from the unskilled dancers’ actions. Third, the Fy of “Nakhwayusu” movement, the GRF show significant differences in E2 (p<.05) with strong propulsions on both of the skilled and the unskilled dancers. Fourth, the Fz of “Nakhwayusu” movement, the GRF show significant differences in E4 and E5 (p<.05) while the unskilled dancers show greater reactions in E4 and the skilled dancers show greater reactions in E5.
