Abstract

Efeito da idade relativa nos jogadores do campeonato brasileiro de basquete da categoria sub-17 PALAVRAS CHAVE: Idade Cronológica. Efeito da idade relativa. Desempenho Desportivo. Basquetebol. RESUMO O objetivo do estudo foi verificar o efeito da idade relativa (EIR) nos jogadores do campeonato brasileiro de basquete sub-17, considerando o sexo e a classificação das equipes. Assim, foi identificado o trimestre de nascimento (quartis) de 540 basquetebolistas (270 de cada sexo). Para compara-los pela classificação obtida, os jogadores foram agrupados nas equipes: "Medalhistas", "Intermediárias" e "Últimas colocadas". Todas as informações pertinentes ao estudo foram obtidas através do site da Confederação Brasileira de Basketball. Para análise dos dados foi utilizado o teste Qui-Quadrado (χ 2 ). Dos resultados obtidos verificou--se uma predominância de atletas nascidos no 1º e 2º quartis (χ 2 =23,78; p<0,001), com maior EIR no sexo masculino (χ 2 =16,74; p<0,001) quando comparados ao feminino (χ 2 =8,45; p=0,038). Em relação a classificação final do campeonato o efeito foi encontrado nos jogadores "medalhistas" do sexo masculino (χ 2 =8,28; p=0,041) e feminino (χ 2 =9,43; p=0,024) e nos jogadores das equipes "intermediárias" do sexo masculino (χ 2 =13,08; p=0,004).

Efeito da idade relativa no Campeonato Brasileiro de Basquete: Categoria sub-15

“…In the present study, for example, RAE was not associated with the performance of men's teams, but it was observed that RAE could somehow influence the results for females, since this phenomenon was found only in athletes from the best classified teams. Similar result was found in U-17 Brazilian basketball players 18 . The association of RAE with the final classification of the team found in this study and in the study of Oliveira et al 18 suggest as a consequence of RAE in the Brazilian Women's Championship a better performance of teams in the U-15 and U-17 categories.…”

However, the same cannot be said about the final classification of men's teams.…”

“…Our findings for females do not corroborate the available literature. In young female basketball players, RAE was observed in French girls aged 7-18 years 5,11 , in Brazilian schoolchildren 17 and in U-17 athletes of the 2015 Brazilian Basketball Championship 18 . Some factors could explain the inconsistency of findings in females such as: less competition in selective processes and lower maturational variability in girls at ages when athletes are usually selected 20,26 .…”

“…In young athletes, Cortela et al 17 found higher proportion of athletes born in the first half of the year, but only among male Schoolchildren athletes. In athletes of the 2015 Brazilian U-17 Championship, Oliveira et al 18 found RAE in both sexes, also associating the results to the best teams.…”
