The kinematic model of the bounce - off phase in some acrobatic elements with forward body rotation

The aim of this study was a comparison of the kinematic parameters important for defining a model technique of the push-off phase in performing acrobatic elements with forward body rotation, as well as the first hand support, the bounce-off and the flight phase, as key phases in performing acrobatic elements with hand support and forward body rotation. The comparison of kinematic parameters was made based on recorded tapes of forward handsprings and handspring saltos forward tucked to roll out, performed by top class gymnasts. It was made on the individual execution phases of the same elements related to the hand support phase, bounce-off hands phase and flight phase. The data was processed with the Ariel Performance Analysis System (APAS, 1995). The values indicating the significance of the handspring salto forward tucked to roll out as an exercise in training methods of the bounce- off hands phase were obtained by analyzing the kinematic parameters essential in defining a correct technique of the bounce– off hands phase, in executing acrobatic elements with forward body rotation and hand support. The correct execution of the bounce– off hands phase makes the achievement of proper flight altitude possible, which is essential for learning more complex acrobatic elements with a high degree of difficulty, whose performance includes multiple rotations around the transversal and/or longitudinal axis.
