“…In combat sports the victory is achieved as a result of a competition with other athlete, that is why the previous sporting success is one of the most objective parameter of the following success. The studies on identifying correlations between performance successes at various stages of preparation in combat sports such as judo (Julio et al, 2011;Barreiros, Côté, & Fonseca, 2012), taekwondo (Sadowski, Gierczuk, Miller, Cieśliński, & Buszta, 2012;Li et al, 2018), Greco-Roman wrestling (Korobeynikov & Radchenko, 2009;Tropin, 2013;Biac, Hrvoje, & Sprem, 2014;Karninčić, Baić, & Sprem, 2017), free-style wrestling (Podlivaev, 2005;Latyshev et al, 2020) have been conducted. The weight classes in combat sports are of a significant importance, although we have not found the studies which would show the dependence of the results at the junior and cadet levels on the results at the senior level in relation to the weight classes.…”
