The aim of this study was to determine the relationship between functional abilities and competitive success on a selected sample of national-level judokas. The study was conducted two weeks before the national championship. The research protocol consisted of the Special Judo Fitness Test (SJFT) and the Multistage Fitness Test (MFT). The SJFT Index was non-significantly higher in non-medalists compared to medalists (p = 0.12, ES = 0.85, moderate). Estimated maximal oxygen consumption (VO2max) was significantly higher in medalists than non-medalists (p = 0.05). SJFT Index (p = 0.04, r = 0.48, moderate) and VO2max (p = 0.03 r = 0.50, large) significantly correlated with competitive success in judo athletes. There was no significant correlation between the SJFT Index and VO2max (p= 0.38, r = 0.24, small). The main findings of this study were: I) medalists performed the SJFT (lower index) better and had a higher VO2max; II) SJFT and VO2max were related to the competitive success of judokas. The results of the study show that significantly higher values of VO2max and moderately better results on the SPJT (lower values of the SJFT Index) are characteristic of judokas who won medals at national championships than those who failed. The results obtained may be a relatively reliable guideline in the future planning of a specific training process ahead of the most important competition during the competition season.
