O exercício físico é responsável por gerar diversas adaptações morfofuncionais, endócrinas, metabólicas e neurais. Dentre elas, destaca-se a melhora na sensibilidade í ação de hormônios como a insulina e a leptina, bem como a modulação nas concentrações plasmáticas dos hormônios GH, IGF-1, testosterona e cortisol, responsáveis pela homeostase energética. A insulina é um importante estimulante na secreção de leptina, ambos exercem papel central na homeostase energética e controle do consumo alimentar no núcleo arqueado do hipotálamo, controlando a secreção de neuropeptídios responsáveis pelo consumo alimentar, tais como: NPY, AgRP, CART e POMC. Esta revisão objetiva elucidar algumas ações do exercício físico relacionadas ao metabolismo e ao consumo alimentar, descrevendo algumas vias metabólicas que ocorrem nos tecidos musculoesquelético, hepático e, principalmente, hipotalâmico, ativadas por hormônios.
Palavras-chave: exercício físico, hormônios, vias metabólicas, consumo alimentar.
