The International Judo Federation (IJF) has often changed the rules to protect judokas, increase the intensity of competitions, score more, and achieve greater attention and popularity. This research aims to determine the impact of judo rule change on the effectiveness of floor techniques in competitors at the Europa Judo Open in Sarajevo 2021-2022. The research was conducted on a sample of (n=217) senior fights and a sample of (n=130) senior women's fights in 2021. and a sample of (n=206) senior fights and a sample of (n=119) senior women's fights in 2022. in all 7 weight categories at the Sarajevo European Open. It was found that the most commonly performed techniques of procedures are Hon-gesa-gatame, yoko-shiho-gatame and sankaku-jime. The highest percentage of osaekomi-waza (holding in the grip) is immediately after the throw, and the highest percentage of shime-waza (choking techniques) were performed after a failed opponent's attack. The percentage of kansetsu-waza (leverage) is reduced. By analyzing, we found that in the lower weight categories there was an increase in ground wins (senior men category: 60kg 7 % in 2021, 19% in 2022,66 kg 22% in 2021, 28% in 2022, 73 kg 11% 2021,32% in 2022), that is, generally the application of parterre techniques during the combat, while in the larger weight categories (81, 90, 100, +100) the percentage of wins in ne-waza decreased slightly (category 81 kg 18% in 2021, 12% in 2022,90kg 19% in 2021, 18% in 2022, 100 kg 18% in 2021, 7% in 2022, +100kg 33% in 2021, 22% in 2022). In the women's categories 48 kg, 52 kg and +78 kg, significant progress was observed (senior women category 48kg 18,75% in 2021, 38,46% in 2022,52 kg 20% in 2021, 25% in 2022, +78 kg 33.33% in 2021, 55,56% in 2022), while in other female weight categories, the efficiency in ne-waza was higher in 2021 (57 kg 32% in 2021,26,32% in 2022, 63kg 31,50% in 2021, 25% in 2022,70 kg 34,78% in 2021, 11,54% in 2022, 78 kg 26,67% in 2021, 25% in 2022). In seniors, control techniques improved slightly while senior women performed better at performing shime-waza and kansetsu-waza techniques compared to 2021 (15,15% in 2021, 25,81% in 2022). With the introduction of new rules in judo, more time space was given to the ne-waza so that growth was recorded in osaekomi-waza, while the number of kansetsu-waza and shime-waza decreased.
