Ergogênicos Nutricionais e Desempenho no Rugby: Revisão Sistemática

Objetivo: Apresentar ergogênicos nutricionais investigados cientificamente envolvendo jogadores de rugby e suas respostas no desempenho em treinos e jogos. Procedimentos Metodológicos: Foi conduzida revisão sistemática na base PubMed em Janeiro de 2013, utilizando-se as palavras-chave no campo resumo: rugby, suplementation, carbohydrate, protein, amino acid e caffeine de forma isolada e/ou combinada. Para análise, foram considerados estudos originais publicados nos últimos 10 anos. Resultados: Na busca inicial foram encontrados 53 artigos. Após leitura dos títulos e resumos foram excluídos 35 artigos. Cafeína e creatina foram os suplementos mais testados e representam 50% dos artigos analisados com jogadores de rugby. Outros suplementos como β-alanina, bicarbonato, carboidrato, HMB e Tribulus terrestris também foram testados e representam os outros 50% dos trabalhos analisados. Apenas cafeína e creatina apresentaram respostas positivas em medidas de desempenho. Conclusão: Cafeína e creatina podem adicionar respostas ao desempenho de jogadores de rugby submetidos a cargas intensas de trabalho. Por outro lado, consumo de álcool apresentou efeito ergolítico.
