recursos ergogênicos; suplementação alimentar; exercícioResumo
Introdução: A cafeína (CAF) é um recurso ergogênico nutricional comumente utilizado durante a prática do exercício físico com o intuito de potencializar o desempenho físico. Não apresenta efeitos agudos adversos, tem baixo custo, facilmente acessível e socialmente aceita. São atribuídos a CAF mecanismos de ação centrais e periféricos durante a prática do exercício físico. Objetivo: O presente estudo tem como objetivo elucidar as atuais evidências sobre os mecanismos de ação da CAF e a melhora do desempenho físico. Métodos: Foram selecionados artigos de revisão sistemática com e sem metanálise e ensaios clínicos sobre suplementação de cafeína e exercício físico. Conclusão: A suplementação com CAF promove melhora do desempenho físico, principalmente em modalidades de endurance, e essa melhora no desempenho é devido aos mecanismos de ação da CAF no sistema nervoso central.
