Description The aim of this study was to analyse the most important parameters determining the quality of the motion structure of the basic classical dance jump – grand jeté. Research sample consisted of 8 students of the Dance Conservatory in Brno. Using the system Simi motion we performed a 3D kinematic analysis of the jump. On the basis of the comparison of structure quality and measured data of the grand jeté, we defined the optimal values of the relevant parameters determining the quality of the performance. The take-off speed should achieve about 2.4 m/s, the optimum take-off angle is 28 - 30 degrees. The take-off leg should swing backward at the beginning of the flight phase with the minimum speed of 3.3 m/s. If motor abilities of dancers achieve the level necessary for optimal performance of a classical dance jump, there is room for certain variability of the structure of the dance jump.
