The purpose of this study was to investigate the kinematic factors during the dismount motion in parallel bars. Six elite gymnasts were participated in this study and were asked to perform double backward somersault in parallel bars. Two video cameras were employed to capture the motions of the subjects. Kwon3D software was used to process and analyze the data. The results obtained from the study were as follows; The average flight time was 0.92sec which reflects the improvement of the technique compared to the previous studies. It was assumed that the longer the flight time the faster the vertical velocity. The vertical position of COM was 209.5cm at the hand take-off and 266cm at the peak. The subjects showed a large vertical and horizontal displacement during down swing phase, which have an influence on the batting phase of swing. The anteroposterior velocity of foot segment had the positive impact on the rotation of the whole body. The magnitude of hyper-extension of the hip joint and shoulder joint seemed to be the critical factors influencing the batting phase of the whole body swing.
