Avaliação da ingestão nutricional de um maratonista de elite do atletismo português

Abstract

Objectivo: Défices ou excessos nutricionais podem impedir o máximo rendimento de um desportista. Assim, estudamos a ingestão nutricional de um maratonista de elite, analisando o grau de adequação às exigências de treino e competição. Material e métodos: Maratonista de elite (32 anos, 1,69m, 55 kg), 4º lugar no Campeonato do Mundo de Atletismo, (2h09"™28" - melhor marca pessoal). Realiza 12 a 14 treinos por semana. Os dados nutricionais foram obtidos por registo de sete dias. A conversão dos alimentos em nutrientes foi realizada pelo programa informático The Food Processor Plus 7.0. Estatí­stica: Utilizaram-se as medidas descritivas, média, desvio-padrão e valores máximo e mí­nimo dos sete dias. Resultados: Aporte diários médios: calorias - 2296 ± 639 Kcal; carbohidratos – 40,6 ± 10,2% (4,42 ± 1,98 g/kg/dia); proteí­nas - 22,9 ± 6,7% (2,1 ± 0,3 g/kg/dia); gorduras – 36,5 ± 6,3%; colesterol – 488,1 ± 102,3 mg; fibras – 8,1 ± 2,8 g; vitamina C – 24,9 ± 12,5 mg; vitamina A – 211,0 ± 130,5 μg ER; Betacaroteno – 163,4 ± 265,5 μg; vitamina D – 3,7 ± 4,1 μg; vitamina E – 7,02 ± 3,4 mg ET. Reduzido aporte de cálcio (387,4 ± 154,5 mg), magnésio (222,6 ± 22,3 mg), molibdénio (2,46 ± 3,42 μg) e iodo (58,6 μg). Conclusão: Este maratonista apresenta um perfil nutricional incompatí­vel com as elevadas exigências do treino e competição, caracterizado pelo reduzido aporte de energia, carboidratos, vitaminas antioxidantes e fibras, com excessivo consumo de colesterol. Este maratonista deve alterar o seu perfil de ingestão nutricional.Palavras-chave: perfil nutricional, esportes, provas de rendimento.
