Resumo

O objetivo deste estudo foi avaliar os efeitos de uma intervenção de educação nutricional de sete semanas no conhecimento de nutrição esportiva (SNK) de nadadores adolescentes do Reino Unido altamente treinados. Quinze nadadores adolescentes nacionais e internacionais (homens = 5; mulheres = 10, 15,5 ± 1,1 anos, 170,2 ± 7,5 cm, 60,3 ± 5,7 kg) participaram do estudo durante sete semanas consecutivas da temporada competitiva de natação. Os participantes receberam 30 minutos de educação nutricional uma vez por semana em um ambiente de sala de aula após terem concluído seu treinamento regular de natação. Um estudante de graduação em nutrição esportiva ministrou todas as sessões de educação nutricional e questionários SNK foram administrados aos participantes antes e depois da intervenção. O escore SNK total médio melhorou em 8,3% (DP = 8,4%, IC 95% = 4,1–12,6; p = 0,006; ES = 1,0) após as sessões de educação nutricional. Individualmente, dez nadadores melhoraram significativamente sua pontuação total do SNK, enquanto quatro nadadores não melhoraram e um nadador teve desempenho significativamente pior após a intervenção. Independente disso, o conhecimento dos nadadores sobre hidratação melhorou em 22,2% (DP = 20,6%, 95% CI = 11,8–32,6, p = 0,004, ES = 1,1) ao longo do período de sete semanas, que foi o único tópico de nutrição a ter uma pontuação de conhecimento significativamente aumentada. O presente estudo sugere, portanto, que uma intervenção de educação nutricional pode influenciar positivamente o SNK de nadadores adolescentes de alto nível.
