Abstrakt: Background: The relative age effect (RAE) suggests that, due to maturity, young athletes born in the first quartiles of the year may have advantages over those born in the last quartiles of the year. Thus, it is important to evaluate the RAE in different sports and to consider the particularities of the subdivisions of the sports categories.
Objective: To analyze the RAE in the top 20 of the Brazilian rankings in different combat sports.
Methods: Observational study that analyzed the national databases for the year 2019 (from categories U-11 to U-18) made publicly available by the Brazilian confederations of karate, taekwondo and fencing. We obtained data on date of birth, age category and body weight of all modalities, type of fencing competition weapon (Epee, Foie and Saber) and type of karate modality (kumite and kata) from the top 20 places in each ranking. The final sample consisted of 1,486 athletes (Age: 14.2 ± 2.3. Male-53.2%. Female-46.8%). To identify the RAE, we performed a contingency analysis and compared the results between the sexes within the same sport.
Results: There was RAE in the U-11, U-12, U-15 and U-17 fencing categories ( p  < 0.05), being higher in the female categories ( p  < 0.05). The RAE was higher for males in the Epee test, and similar between the sexes for the Saber and Foie tests. In karate, RAE occurred in categories U-14 and U-16 ( p  < 0.05), being higher in males ( p  < 0.05). The RAE was similar between the sexes in the kumite modality ( p  < 0.05). There was no RAE for the kata modality in karate ( p  > 0.05) and for the Taekwondo categories ( p  > 0.05).
Conclusion: The results showed the existence of a relative age effect in elite athletes ranked (top 20 places in each ranking) only for the sport of fencing and karate kumite.
