The purpose of this study was to analyze variability of kinematic factors in backward illusion motions of rhythmic gymnastics. The subject of this study selected one woman gymnast as the only one who could afford to demonstrate a challenging rhythmic motion of 9 serial turns among worldwide rhythmic gymnasts. Three-Dimensional motion analysis with 7 infrared cameras (sampling frequency: 100Hz) was performed for this study. The data accepted from cameras was analyzed for the kinematic factors by each rotation by using Qualisys Track Manage and Visual3D. As consecutive 9 Backward Illusion Motion achieved, athletes revealed following characteristics. 1) The Z axis motion of COG, supporting leg and swinging leg’s ankle and head apex were more consistent than X and Y axis motions and back-and-forth motions. According to analysis on consistency of velocity components in swinging leg’s ankle and head apex, it was also found that the horizontal velocity was relatively low in consistency. According to analysis on consistency of trunk’s adduction and abduction and knee angle of supporting legs, it was found that abduction motions had relatively higher consistency than adduction motions, and the flexion and extension of knee joint worked in motion with high consistency.
