Biomechanical modelling of selected jump and turn techniques of modern rhytmic gymnastic

Introduction: In the technical coordinative sports disciplines movements need to be performed on top level. This requires the motor training to supplement through mental learning. Model objects with determining biomechanical parameters are required for it. Aims: Biomechanical lines and values have been evaluated to characterize and qualify the performance of leaps and turns. The results should influence the training process to improve performances and to create feedback by using motion capture systems. Methods: Four movements each of them in ten trials of a skilled dancer were captured with the “Vicon motion capture system 460”. The “Grand Jete”, “Cosak jump”, “Cosak jump with turn” and the “turn” . Considering the relevant Variables of a jump or turn that influence performance where analysed, graphs and values calculated. Results: The performance of a leap requires a long time of projectile motion. In consideration of the judgement in Championships also the height and the distance of a jump are judged by the jury. With respect to the laws of constant acceleration the vertical take off velocity therefore is the most important factor. Irgendwas zum turn. Conclusions: The present study should be regarded as a first step into a new area of biomechanics. Although there are several researchers all over the world who engage in the physics of the dance and gymnastics, the analysis with motion capture systems gives a new and more clearer view in this scope
