Biomechanics of the stag leap take-off phase in rhythmic gymnastics

The purpose of the study is the biomechanical analysis of the stag leap take-off phase in rhythmic gymnastics. Research methods and organization. Instrumental methods of tensor dynamometry and high-speed video recording were utilized. The study involved two gymnasts, both holding the title of 'candidate for master of sports', who performed four jumps each. Research results and conclusions. The conduct of empirical measurements allowed for the quantitative description of the pushing technique. A number of biomechanical indicators were deter-mined: the peak impact load during the push-off, the impulse of the pushing force, the initial vertical velocity at the moment of take-off from the support, the jump height, and the direction of the reaction force vector of the support. Based on the obtained data, the phase composition of the push-off was identified.
