      The difference of chronological age in an age group is called Relative Age (RA) and its consequences on the performance of athletes is called Relative Age Effect (RAE). It is believed that the RAE among young athletes can affect their competitive success in many ways, even into adulthood. Thus, the objective of the present study was to investigate the EIR in all judo competitors of the national competitions of the year 2013, making the differentiation by age categories and the competitive performance. This study included 862 male athletes and 637 female athletes. The chi-square was used to compare the observed and expected values among quartiles, adopting significance as p < 0.05. A post hoc Bonferroni analysis was used to identify where the significant differences were (adjusted p < 0.00417). The results showed a significant difference in the male sub-15 categories (Q2 in G1: OV= 17, EV = 9.7, p = 0.001) and male sub-23 (Q1 in G3: OV= 37, EV = 10.1; p < 0.0001). In conclusion, the RAE was only identified in male athletes. However, there was great discrepancy between athletes born in the first semester and athletes born in the second semester. ; A diferença da idade cronológica em uma faixa etária é chamada de Idade Relativa (IR) e suas consequências no desempenho de atletas é chamada de Efeito da Idade Relativa (EIR). Acredita-se que o EIR entre atletas pode afetar o sucesso competitivo de diversas maneiras, até mesmo na idade adulta. Dessa forma, o objetivo do presente estudo foi investigar o EIR em todos os competidores de judô das competições nacionais do ano de 2013, fazendo-se a diferenciação por categorias etárias e o desempenho competitivo. Fizeram parte da presente investigação 862 atletas do sexo masculino e 637 do sexo feminino. O qui-quadrado foi empregado para comparar os valores observados e esperados entre quartis, adotando-se significância como p < 0,05. Uma análise post hoc de Bonferroni foi utilizada para identificar onde estavam as diferenças significativas (p ajustado < ...
