Abstract

The aim of this study was to determine whether the change in the competition rules initiated the existence of differences in situational efficiency of elite judo athletes at two world championships. Observational methodology have been used in the study, based on principle of performance analysis in sport. Data collection was carried out with the help of valid Lince software. The sample consisted of 280 fights in the men's competition, 140 fights from the World Championship held in 2011 in Paris and 140 fights from the World Championship held in 2014 in Chelyabinsk. From each of the seven weight categories twenty most important matches were analyzed (all matches from the 1/8 finals, ending with a final battle).
