Abstract. The aim of this research was to determine which kinematic parameters have the most important influence on success in performing the basket to handstand maneuver. The research sample consisted of fifteen attempts of the basket to handstand performed without a mistake and fifteen attempts performed with a medium or a big mistake according to the regulations. All the attempts were performed by a European and World Champion on the parallel bars, while the success of the attempts was scored by three internationally accredited sports gymnastics judges. The obtained results showed that the success of the analyzed element could be predicted based on the angular velocity of retroflexion in the shoulder joint, the shoulder joint center velocity and the angle of the shoulder joint during the first phase, then based on the body center of gravity (bcg) velocity, shoulder point velocity and the angle of the hip joint in the second phase and bcg velocity, angle of the shoulder joint and hip joint, and the size of the angular velocity of anteflexion in the shoulder joint in the third phase. The research model could, in general, be applied to all sports where the performance technique has an important influence on the final result.

PREDIKCIJA USPEŠNOSTI KOVRTLJAJA DO STAVA U UPORU NA RAZBOJU BAZIRANA NA KINEMATIČKIM PARAMETRIMA – STUDIJA SLUČAJA
Cilj ovog istraživanja bio je da se utvrdi koji kinematički parametri imaju najveći uticaj na uspeh u izvođenju kovrtljaja do stava u uporu na razboju. Uzorak istraživanja činila su petnaest pokušaja analiziranog elementa izvdena bez greške i petnaest pokušaja izvedena sa srednjom ili velikom greškom u izvođenju. Svi pokušaji su realizovani od strane evropskog i svetskog šampiona na paralelnom razboju, a uspšnost u izvođenju pokušaja procenjivala su trojica međunarodnih sudija muške sportske gimnastike. Dobijeni rezultati su pokazali da se uspešnost u izvođenju analiziranog elementa može predvideti na osnovu ugaone brzine retrofleksora u zglobu ramena, brzine centra ramenog zgloba i veličine ugla u ramenom zglobu u prvoj fazi, a zatim na osnovu brzine težišta tela (BCG), brzine tačka ramena i veličine ugla u zglobu kuka u drugoj fazi i brzine BCG, veličine ugla u ramenom zglobu i zglobu kuka, kao i ugaone brzine anteflekion u ramenom zglobu u trećoj fazi. Istraživanje može poslužiti kao model koji se može primeniti na sve sportove u kojima tehnika izvođenja ima važan uticaj na konačan rezultat.
