Resumo

Este estudo teve como objetivo analisar as relações entre eventos competitivos de natação, classificação funcional e idade relativa e detectar se a idade relativa afeta o desempenho em nadadores e paranadadores brasileiros. Os dados foram recuperados de bancos de dados públicos e as datas de nascimento foram classificadas em quatro quartis (Q1 = janeiro-março; Q2 = abril-junho; Q3 = julho-setembro; Q4 = outubro-dezembro). Utilizou-se estatística descritiva, teste Qui-quadrado e ANOVA. Os 50 m livre é a prova competitiva com 2.349 nadadores, seguido de 100 m (n = 1.817) e 200 m livre (n = 905), e 200 m borboleta com 42 nadadores. Os paranadadores estão distribuídos principalmente nas classes funcionais S14, S6 e S5 (n = 140, 87 e 45), e as provas individuais de medley foram menos representadas em SM3, SM9 e SM11 (n = 1 nadador). A maioria das provas de natação (86,36%) e classes funcionais de paranatação (51,43%) são representadas por nadadores e paranadadores nascidos no primeiro e segundo quartis. Associações moderadas entre classificação funcional e idade relativa foram observadas (p < 0,0001, V de Cramer = 0,277). Não foram observados efeitos da idade relativa no desempenho de nadadores e paranadadores (p > 0,05). A grande classe funcional parece estar relacionada com a idade relativa dos grandes paranadadores. A distribuição por quartis mostra a vantagem de ter nascido nos primeiros meses do ano para ser registrado entre os mais talentosos nadadores e paranadadores brasileiros.
