Resumo

Objetivo: Levantar, discutir e sintetizar as pesquisas que analisaram os efeitos do consumo proteicosobre a hipertrofia muscular ocasionada pelo treinamento resistido.Fontes de dados: A pesquisa foi realizada nas bases de dados do Pubmed. Os descritores utilizados foram: Protein consumption, Protein intake, Resistance exercise, Resistance trainning, Hypertrophy, Exercise, Nutrition.Síntese dos dados: O rastreamento dos estudos utilizando os descritores encontrou 73195 estudos. Após cruzamento entre os descritores, obteve-se 4.412 estudos. Desses, depois de realizada análise dos títulos dos estudos, foram cogitados 502 relevantes referências; Após leitura dos resumos 120 estudos foram selecionados, sendo então submetidos aos critérios de inclusão/exclusão, totalizando, ao final, 47 estudos, lidos integralmente. A maioria dos estudos relacionou a prática do treinamento resistido e a capacidade de síntese de proteínas musculares cujo efeito está associado, entre outros fatores nutricionais, a ingestão de quantidades diárias relativamente maiores de proteínas de alta qualidade aminoacídica.Conclusões: A prática de treinamento resistido é capaz de potencializar a síntese de proteínas musculares aguda e cronicamente. Atletas que realizam essa modalidade necessitam consumir uma quantidade diária relativamente maior de proteínas ricas em aminoácidos essenciais para recuperar o dano tecidual muscular ocasionado pelo treino. O consumo aproximado de 20-25g de proteínas, preferencialmente com valores significativos de leucina, parecem potencializar a síntese e recuperação miofibrilar especialmente no pós-treinamento, entretanto a magnitude da hipertrofia ocasionada por esse tipo de exercício é também influenciada por fatores metabólicos, tensionais e hormonais.
