New research reveals that the benefits of exercise extend far beyond muscles, directly reshaping the brain's structure. In a study on mice, researchers observed that repeated treadmill sessions strengthened neural connections and primed specific neurons for faster activation. This " neural rewiring" was essential for the gradual improvement of running endurance in mice. Nicholas Betley, a neuroscientist and study co-author, explains: " Exercise is not just about muscles breaking down and building up—it's changing your whole brain." These findings demonstrate that the brain actively participates in enhancing physical abilities through practice, transforming our understanding of the profound mind-body connection.
