Running Changes the Brain: the Long and the Short of It

This research explores how running impacts brain health, specifically neurogenesis in the hippocampus, a region vital for memory. It demonstrates that voluntary running increases the growth of new neurons, enhances synaptic plasticity, and improves memory and learning in both rodents and humans. Exercise triggers neurotransmitter changes, elevates growth factors like BDNF, and boosts neural connections in critical brain regions. These changes contribute to better spatial navigation, memory discrimination, and potentially delay age-related cognitive decline. The findings highlight the dynamic interaction between physical activity and brain adaptability.

Regular aerobic exercise, such as running, can improve memory and cognitive flexibility by stimulating neurogenesis and enhancing brain plasticity. Activities involving moderate to vigorous intensity several times a week are optimal. These recommendations are based on robust evidence from animal studies and corroborated by human trials. However, individual variations may occur, and consultation with health professionals is advised for tailored exercise plans.
