Kinematic efficiency of the "Moznik" element performance

The aim of this research was to determine objective kinematics parameters of “Moznik” element which differ a successful performance from an unsuccessful one. For the purposes of this research twelve typical performances of the “Moznik” element were selected. Acquisition of kinematics parameters was done with the software system DartFish (Video Analysis Solutions). On the basis of the obtained data a set of 37 kinematics variables was formed. The results of this study showed that the angle of the hand in relation to the bar in a successful performance significantly differs from the one in an unsuccessful performance. It is evident that in the case of the successful performances, the so-called “whip” begins a bit later. It has also been found that after the release of the bar, the angles in the shoulders are considerably more open in successful performance than in an unsuccessful one.
