The aim of this study was to determine the extent to which different levels of strength abilities of the right and left lower extremities affect the quality of the motion structure of the selected classical dance jump, the cabriole en avant. The sample consisted of eight students from the Dance Conservatory in Brno. Strength abilities of the lower extremities have been investigated using a test called the vertical jump. To analyze the quality of the jump, we have chosen a kinematographic method for which we used the SIMI Motion analytical system. The total of 48 jumps was measured with each dancer performing three jumps using their right lower extremity and three jumps using their left lower extremity. Through movement digitization we were able to obtain the kinematic characteristics from which we were primarily interested in time and speed parameters of the lower extremities movement. The calculated Spearman correlation coefficients failed to confirm a statistically significant relationship between the observed variables. This result points to the presence of other factors which significantly affect the quality of the jump execution. Based on the results and expert assessment of individual jumps we have created a model of the optimally performed cabriole en avant jump. Through its presented findings this work aims to help dancers and their teachers to understand essential mechanical principles affecting cabriole en avant and thus to be able to correct technical deficiencies faster and more effectively.
