Sažetak
The aim of this study was to determine the differences in the performance of the initial part of the preparatory acrobatic series (PAS) including Run-up, Hop, Round-off and Back handspring, that precede the execution of three basic variants of backward somersaults: Tuck, Layout and Double tuck. The subject of this research was the member of the Croatian national male gymnastics team, ranked among the top 20 gymnasts in the world on the floor exercises. After performing 10 of each somersault variants, the best 3 are subjected to further analysis. The sample of variables consisted 22 kinematic parameters with the greatest impact on the height and length of the somersault trajectory, as well as on the generation of the necessary angular momentum. Based on the results obtained by the correlation analysis specific relations among biomechanical parameters are defined (p < 0, 05). This particularly applies to the COM height in second Run-up step (.71), horizontal velocity during the take- off for Hop (0.76), length of the Hop (0.81) and to the horizontal velocity at a maximal Hop height (0.78). The results of this research can be used in everyday gymnastics practice, in terms of a better understanding of the technical execution, the identification of errors as well as the efficiency maximization of the preparation for somersaults.
