THE KINEMATIC DYNAMIC STRUCTURE OF EFFECTIVE GIANT SWINGS BACKWARD PRIOR TO DIFFICULT DISMOUNTS AND FLIGHT ELEMENTS ON HORIZONTAL BAR AND UNEVEN BARS

Abstract

The purpose of this study was to investigate into the kinematic dynamic structure of dismount giant swings backward executed effectively on horizontal bar and uneven bars. The functional dependence of angular momentum, vertical velocity and reaction force of the bar and their relation with the beat leg swing were demonstrated. A double peak in the force curve with physically determined intervals of the maximums is typical. The position of the 1st maximum, the so-called hang, determines the kind of dismount (before or over the bar) and the effectiveness of leg swing. On the uneven bars, a too late hang is a frequent mistake. A leg swing with only a low degree of efficiency and a small height in the dismount result from this. The learning time for difficult dismounts and flight elements can be shortened by feedback about the 1st force maximum in the dismount giant swing.
