The purpose of this study was to present basic data of giant circle backward to handstand on uneven bars by means of kinetics and kinematics. Three female junior gymnasts volunteered as subjects. Their body weight and height was 30.0 ± 2.68 kg (mean ± SD) and 1.37 ± 0.06 m (mean ± SD), respectively. Motions were filmed from the side with a high-speed camera of 50 frames a second. Reaction force of the high bar was measured by strain gauges. Prior to filming, the bar was calibrated by force application. During the performances, the voltage output representing the force subjected to computer analysis. They were normalized by dividing force by body weight. Films were digitized and hip and shoulder joint angles were calculated. Center of mass was calculated from the data of Matsui (1958). Reaction force of the high bar had 2 peaks. First Peak force was the maximum value. After the gymnast passed the low bar, the upswing was initiated by lifting the legs upward from the hip. Then first peak force was appered. The value of the first peak force was 5.12 ± 0.19 kgw/kg (mean ± SD). This force accelarated the body to the upward. The gymnast arched after the piked. Then second peak force was appered. The value of the second peak force was 3.24 ± 0.26kgw/kg (mean ± SD). This second peak force accelarated the body above the high bar. These results suggest that the pike and arch on the upswing a re necessary to success the giant circle backward to handstand on uneven bars. This normalized force may be useful in correction of errors in execution of the swing for biofeedback training. |
