35Analysis of the kinetic performance of some kinematic variables of world champions in the Tokyo Olympics in long jump (2021)

Abstract

There are many factors that cause a significant impact, which is evident from the researcher's observation of global achievements that there are differences in achievement levels with long jump players due to the difference between physical specifications and performance,  the aspect related to physical and technical training and the lack of sufficient attention to the analysis engine for players, so the researcher saw that studying the correlation and the percentage of contribution of some kinetic variables specific to the effectiveness of the long jump for world champions participating in the Tokyo Olympics (2021) AD and that the kinematic research variables, including horizontal and vertical speed, take-off angles, trunk and speed of the penultimate step, to be a good model for global dynamics, attention was paid to studying these variables To make it closer in the kinetic analysis to determine the series of strengths and weaknesses of the participating players, the kinematic variables were adopted for the best (12) players from the world champions participating in the Tokyo Olympics. The race was held over two separate days on 1-3/8/2021 AD and those who obtained the first places and qualifications within the International Federation law for the best qualifying number set by the International Federation (6,729) m and with a number of 12 players out of 28 players participating in the long jump event, the best attempts for each player were analyzed and the variables under study in athletics.
