Exercise influences the brain in a hormetic way, and it happens through the microbiota
In today’s post, we would like to present our latest work published by our laboratory. In this study, we sought to shed light on a key question in the Neurobiology of physical exercise: how do intensity and duration of exercise modulate its beneficial effects on cognitive function and hippocampal neurogenesis? Our results, published this month in eBioMedicine (The Lancet, 2025), uncover the mediating role of the gut microbiome in this relationship, revealing not only the importance of dosing exercise, but also how our intestinal flora acts as a fundamental axis in mediating the beneficial effects of exercise on the brain. https://www.csic.es/es/actualidad-del-csic/la-microbiota-modula-el-impacto-positivo-del-ejercicio-fisico-moderado-sobre-la-memoria-segun-un-estudio-del-csic We employed a mouse model subjected to different aerobic exercise protocols: one moderate, another prolonged, and one at higher running speed. The most striking finding is that only moderate exerc...
