Purpose: to reveal the effect of special physical preparedness of athletes on the biomechanical characteristics of the performance of the kick-step component of the main course in acrobatic rock'n'roll. Material & Methods: following research methods were used: theoretical analysis and generalization of data from special scientific and methodological literature; pedagogical observation; biomechanical computer analysis; video of the final of the category Juvenile of the Ukrainian championship (2017) from acrobatic rock'n'roll. Results: a biomechanical analysis of the performance of the kick-step component of the main course; the amplitude of the performance of the kick-step component of the main move of the Juvenile category in acrobatic rock'n'roll. Conclusion: the level of special physical preparedness of the Juvenile category athletes is determined; based on the biomechanical analysis of the performance of kick-step athletes in the main course, changes in the angle of the knee and hip joints of the legs at the beginning, middle and end of the competition program.
