QUANTITATIVE ANALYSIS OF THE DYNAMIC BALANCE ABILITY BETWEEN THE COLLEGE STUDENTS AND HANDBALL PLAYERS

Abstract

The purpose of this study was to investigate the differences of dynamic standing ability (Balance keeping time; BKT) and the change of the angular velocity (deg. / s) of a platform between healthy non-athelete female students and handball players using an unstable platform-like seesaw. Methods: The seesaw is capable of rotating side to side in both directions of right and left; it was set horizontally at an angle of zero degrees as a base, with the maximum degree of the seesaw inclination set at 25 degrees. In addition, a high-speed digital video camera (SONY-HDR-CX520V) was set to record the BKT and the changes of motion in the frontal plane from both sides of the plate. Results: There is a significant difference observed in both BKT and the change of angular velocity between non-athletes and handball players. Conclusion: The findings suggest the data gained from the experiments may establish a dynamic balance fitness norm and can be used as an assessment method of the lower extremity coordination ability.
