THE KINEMATIC ANALYSIS OF GIANT SWING AND DISMOUNT OF DOUBLE SALTO BACKWARD STRETCHED WITH 720°TURNS ON HORIZONTAL BAR

Abstract

The main purpose of this study was to analyze the kinematic characteristics of the Giant Swing Leg Beating Action on the horizontal bar and in addition, the movement of leaving bar during dismount of Double Salto Backward Stretched with 720°Turns. 3D kinematic data of one international top class (S1) and national level gymnasts (S2) were collected by using Peak Performance 3D Motion Analysis System. The data was obtained during final competition of the horizontal bar routine in 1998 International China Motor Cup Gymnastics Meeting. The results indicated that better performance was demonstrated if gymnasts could make use of the inflection of shoulders and hips to alternate the moment of inertia. This created the active moment that was required to accelerate body swing so that higher velocity can be gained when leaving the bar.
