Objetivo: Este estudo teve como objetivo analisar os efeitos do exercício físico sobre os biomarcadores hepáticos em indivíduos adultos. Métodos: Realizamos uma revisão sistemática e metanálise seguindo as recomendações PRISMA e registradas no PROSPERO (CRD42022337749). Pesquisamos MEDLINE (via PubMed), Scopus, SPORTDiscus e Web of Science, usando os termos 'exercício', 'doenças hepáticas' e 'biomarcadores' do Medical Subject Headings (MeSH). Resultados: Quatorze estudos alcançaram a elegibilidade com um total de 485 participantes. As intervenções variaram de quatro a 12 semanas, com duração de 24 a 90 minutos por sessão, com três a cinco sessões por semana. Intervenções com exercícios aeróbicos e resistidos, com ou sem aparelho vibratório e implementação de dieta, demonstraram redução de diferentes biomarcadores hepáticos, como aspartato transferase (AST), alanina transferase (ALT), gama-glutamil transferase (GGT), fosfatase alcalina ( ALP), albumina (ALB), ferritina (Fe) e bilirrubina indireta (Bil). Os principais resultados da meta-análise não mostraram diferenças significativas em ALB, GGT, AST e ALP. No entanto, houve uma diferença significativa na ALT (SMD: -0,41, IC 95%: -0,71 a -0,11, p = 0,008, I2 = 0%). Conclusão: O exercício físico (por exemplo, treinamento resistido, treinamento aeróbico, treinamento intervalado de alta intensidade) favoreceu a redução de AST, ALT, GGT, ALP, ALB, Fe e Bil. Este estudo apontou que a prática regular de exercício físico pode ser uma estratégia eficaz e recomendável para minimizar os efeitos deletérios das doenças hepáticas.
