TECHNICAL PREPAREDNESS OF UKRAINIAN HIGH JUMPER

Abstract

During 1990–2022, Ukraine was successfully represented at the Olympic Games, World and European Championships by high jumpers: Inga Babakova, Vita Stepina, Vita Palamar, Iryna Mykhalchenko, Yaroslava Maguchykh, Yulia Levchenko, Iryna Gerashchenko, Oksana Yukuneva, Kateryna Tabashnik, Yulia Chumachenko and other. The aim of the work: to improve information on the peculiarities of technical readiness of Ukrainian high jumpers. Task: investigate the indicators of technical readiness of Ukrainian high jumpers according to the time characteristics of the technique of takeoff, repulsion, and flight over the bar. Methods: we conducted pedagogical observation of high jump at the Ukrainian Athletics Championships in 2009, 2018, the Cups of Ukraine in 2011, 2012, and the All-Ukrainian High Jump Competition "Memorial of Oleksiy Demyanyuk" in 2020 with the help of video recording (Sony HDR-PJ50E video camera). All videos were analyzed using the program - Tracker - 4.87. The following time characteristics of technical readiness are determined: duration of reference, flight, periods of all take-off steps, duration of repulsion, and flight through the bar. Indicators were calculated: the rate of all take-off steps, the contrast of the growth rate, the rate intensity, the rate mobilization, the coefficients of activity of the take-off steps, and the activity of the passage through the swing leg. Results and conclusions: new data were obtained on the duration of reference and flight periods of all steps of the ten leading jumps of Ukraine. The data of scientific and methodical literature on quantitative characteristics of technical readiness (rate of the third, penultimate, and last run steps, activity coefficient of the last run step, and duration of repulsion) in highly qualified high jumpers are confirmed. Despite the density of the results of the high jump, as the best result and the result during the observation, the jumps differ significantly in terms of contrasts: the growth rate of the last steps of the run, rate mobilization, and the activity of the passage through the swing leg in the last step.
