Resumo

Considerando a elevada demanda fisiológica do Crossfit, caracterizada por esforços intermitentes de alta intensidade que exigem adequada oferta energética e estratégias de recuperação, observa-se a necessidade de intervenções nutricionais que otimizem desempenho, composição corporal e tolerância ao exercício. Objetiva-se analisar, por meio da literatura científica recente, as principais estratégias nutricionais aplicadas a praticantes da modalidade, bem como seus efeitos sobre performance, recomposição corporal e marcadores fisiológicos. Para tanto, procede-se a uma revisão integrativa realizada nas bases BVS e PubMed, utilizando descritores relacionados a estratégias nutricionais, CrossFit e recomposição corporal. Após aplicação dos critérios de inclusão, nove estudos foram selecionados para análise e síntese. Desse modo, observa-se que suplementos como cafeína e bicarbonato de sódio apresentam resultados positivos em alguns cenários, sobretudo na melhora da tolerância ao esforço e no aumento do volume de trabalho, embora efeitos inconsistentes também sejam reportados. Estratégias alimentares como a dieta mediterrânea demonstram benefícios sobre desempenho, recuperação e saúde metabólica, enquanto a dieta cetogênica evidencia melhora na composição corporal, porém com possíveis impactos negativos em exercícios anaeróbicos intensos. Tais achados reforçam que a resposta às intervenções varia conforme individualidade biológica e demandas específicas do treino. O que permite concluir que a nutrição esportiva, quando individualizada e integrada ao planejamento de treinamento, exerce papel determinante na performance e recuperação de praticantes de CrossFit, evidenciando a importância da atuação profissional baseada em evidências.
