Resumo

Introdução: O exercício transformou-se numa opção de estilo de vida para muitos indivíduos que procuram manter a sua saúde e reduzir o risco de diversas doenças. No entanto, para exercer uma determinada intensidade, é necessário um gasto energético importante e pode provocar microdanos nos músculos, que podem ser detetados através de vários biomarcadores, entre eles os níveis do Fator de Necrose Tumoral Alfa (TNF-α). Esta condição pode afetar os níveis de desempenho físico, o que leva algumas pessoas a tomar suplementos como medida preventiva. Além disso, o consumo de cafeína após o treino ganhou popularidade, principalmente sob a forma de bebidas com cafeína, num sumo para melhorar a forma física e a produtividade. No entanto, a investigação exaustiva sobre os mecanismos pelos quais a cafeína afeta a recuperação após o exercício é limitada.
Objectivo: Este estudo pretende investigar as alterações dos níveis do Factor de Necrose Tumo-ral Alfa (TNF-α) para além do consumo de café e do consumo submáximo.
Metodologia: Este estudo cuantitativo quasi-experimental empregou um projeto simples. Muitos homens adultos (19-29 anos) dividiram-se num grupo de controlo (CON) e num grupo experimental (EXP). O grupo EXP consumiu café Robusta durante cinco dias antes da intervenção de exercício, enquanto o grupo CON recebeu um placebo nos mesmos dias. Todos os participantes realizaram um exercício submáximo utilizando o método de teste de passos da Associação Cristã de Jovens (YMCA). Duas horas após esta intervenção, foram reconhecidos valores sanguíneos extra para a medição do TNF-α.
Resultados: Os níveis de TNF-α foram mais baixos no grupo de intervenção (88,17 n/L) do que no grupo de controlo (121,44 n/L), embora a diferença não tenha sido estadísticamente significativa.
Conclusões: O consumo de café pode ajudar a reduzir o TNF-α e a regular a inflamação após exercício submáximo.
