The purpose of the research is to determine the correspondence between the dynamic characteristics of the simulation exercise and the sliding step in highly qualified cross-country skiers, as well as the possibilities of their application for assessing the level of speed-strength training.
Methods and organization of the research. The dynamic and temporal parameters of the foot push-off were recorded in 12 male and 8 female cross-country skiers using a strain gauge platform. The study involved highly qualified skiers, Masters of Sport, aged 19-22 years: 12 male and 8 female cross-country skiers.
Research results and their discussion. The dynamic characteristics of a simulated sliding step exercise during a push-off with the foot were determined. A comparative analysis of the movement characteristics of a simulated skiing exercise with a sliding step was conducted. The force parameters of the leg push-off during simulation of ski strides by elite cross-country skiers were determined for the vertical, horizontal, and lateral components. The time of force application for all components was identified, enabling the calculation of impulse and force gradient.
Conclusion. It is recommended to use the dynamic characteristics recorded during the simulation exercise as indicators of the level of speed and strength training of a cross-country skier.
