Comparative kinematic analysis of airbone phase in acrobatic elements from „stuff position“

Acrobatic rock ’n’ roll is a blend of dance and acrobatics. The aim of this investigation was to determine differences in three acrobatic elements performed from stuff position in airborne phase. These three elements are simple stuff take off, tucked somersault forward and tucked somersault backward. The investigation was performed by acquisition video on the Masters tournament in Zurich. For the purposes of this research, the demonstration of techniques was performed by 20 dance couples who were referred on the competition into the quarter finals, semi finals and the finals of tournament. To determine the difference between acrobatics elements, it was used a nonparametric statistic method Kruskall-Wallis test for independent groups. To determine statistically significant difference between analyzed elements, it was carried out by use of discriminative analyzes. These analyses lead us to conclusion that there is a statistically significant difference in values of certain variables that describe airborne phase of all three elements of technique. The variable duration of airborne phase makes no difference between analyzed elements, the height of flight makes a difference between stuff take off and both of somersaults and all the other variables differ all three elements among each other.
