Two strategies in relative movements in the flight phase of a horizontal bar dismount

I. Kyuchukov

Abstract: In this study, we present and analyse two possible strategies for the execution of relative movements for initiating a twist in a horizontal bar dismount – double back straight somersault with a twist - 1080°. A mathematical model for computer simulations of aerial movements was applied. The model consists of 16 rigid segments with 15 joint connections and 32 inner degrees of freedom. An aerial and a support option for the initiation of longitudinal rotation were simulated for this rather difficult dismount. Despite the relatively belated beginning of the longitudinal rotation, in the aerial option, a slightly greater angular velocity around the body’s longitudinal axis (up to 25.8 rad/s) than in the presented model with support (23.3 rad/s) was achieved. In both options, the athlete should execute the relative movements in the flight phase accurately to realize the dismount successfully.
