Resumo

Já foi bem estabelecido que, após a realização de exercícios aos quais não se está acostumado, principalmente se esses envolverem contrações excêntricas, ocorre um processo conhecido como dano muscular (DM). Esse processo consiste na desorganização e/ou rompimento de células musculares graças a elevados níveis de estresse mecânico e/ou metabólico. Sabe-se que, após a ocorrência do DM, o músculo acometido se recupera e passa a ser mais resistente a esse fenômeno, apresentando respostas atenuadas desses sintomas, fenômeno conhecido como efeito protetor (EP). Entretanto, para a manifestação deste efeito por meio de contrações excêntricas, é necessária a ocorrência de DM de alta magnitude, o que pode não ser interessante para atletas e entusiastas da atividade física. Recentemente, diferentes estratégias de proteção contra o DM que não envolvem a realização de contrações excêntricas máximas vêm sendo apresentadas, como a realização de contrações excêntricas submáximas, contrações isométricas, treinamento de flexibilidade e aumento da temperatura muscular previamente ao exercício. O objetivo do presente estudo foi revisar essas estratégias de proteção contra o DM para melhor entender esse fenômeno. Foi realizado um levantamento em importantes bases de dados e, os artigos encontrados e considerados relevantes ao tema foram revisados e didaticamente explanados ao longo do trabalho.
