Abstract

In dance sport, hip movement is the most basic and essential technique, connecting the body movements to make the body move organically, and providing an overall balance of body movements. From that perspective, this study focused on the Cucarachas movement, representing a series of efficient hip movements in the center of gravity. For the purposes of this study, 4 dance sport participants who had won prizes at international contests were selected in order to analyze such variables as the radius of gyration (shift) on the hips and the shift of the center of gravity when scapula depression was performed and when it was not. To examine differences in these kinematic variables, a paired t-test was conducted, resulting in the following findings: First, the dancers were found to be able to control scapula depression, and a significant difference was observed in the vertical axis(Z) between the times when scapula depression was performed and when it was not. Second, when scapula depression was performed, shifts in the left-right axis(X) and anterior-posterior axis(Y) were found; the left-right axis showed a greater difference than the anterior-posterior axis. Third, scapula depression was found to have an influence on the shift to the left-right axis(X) of the center of gravity.
