Purpose: to conduct a comparative analysis of competitive performance indicators of wrestlers at the Junior (U20) and Senior (U23) World Championships. Material and Methods. An analysis of official protocols and video recordings of the 2025 Greco-Roman Wrestling World Championships was carried out: the Junior U20 World Championship in Novi Sad (Serbia) and the Senior U23 World Championship in Samokov (Bulgaria). In total, 571 matches were analyzed: 272 matches at the U20 World Championship and 299 matches at the U23 World Championship. The initial performance data of the athletes were obtained from the official website of the International Federation of Associated Wrestling Styles (UWW). The analysis of competitive activity was performed using an internet-based platform (Performance Data Analysis – PDA). Results: The analysis of matches at the 2025 Greco-Roman Wrestling World Championships among Juniors (U20) and Seniors (U23) made it possible to identify effective actions that were scored by referees. At all championships under study, the highest number of points was awarded for the same actions: in parterre – gut wrench and lifts suplexs; in standing position – passivity and take down. No statistically significant differences (p>0,05) were found in any of the referee-scored actions between the 2025 U20 and U23 World Championships. It was determined that the percentage of points scored in the standing position was higher at the U23 World Championship (56,58 %) than at the U20 World Championship (54,90 %), whereas the percentage of points obtained from technical actions was higher at the U20 World Championship (71,84 %) compared with the U23 World Championship (68,26 %); however, these differences were not statistically significant (p>0,05). The greatest number of points scored by wrestlers of both age groups occurred in the second minute of the match, while the lowest number was recorded in the sixth minute. No statistically significant differences (p>0,05) were observed in the percentage distribution of points scored in each minute of the match at the analyzed World Championships. The average number of points scored per match and the number of points scored per minute were significantly higher (p0,05). Conclusions. The conducted research indicates the presence of both common and distinctive features in the competitive performance indicators of Greco-Roman wrestlers at the Junior (U20) and Senior (U23) World Championships. Common characteristics include the predominance of simple technical and tactical actions with minimal point values (one- and two-point actions), a considerable proportion of matches ending with a 1:1 score, and a large number of interruptions caused by the use of challenges and the recording of rule violations. These factors negatively affect the spectacle of competitive wrestling. At the same time, it was established that the average number of points scored per minute and per match was statistically higher (p
