Physical-exercise increases adult hippocampal neurogenesis in male rats provided it is aerobic and sustained

This study explored how different types of exercise affect adult hippocampal neurogenesis (AHN) in male rats. Sustained aerobic exercise, like running, significantly enhanced AHN, which supports learning, memory, and stress resilience. In contrast, high-intensity interval training (HIT) and resistance training showed minimal or no benefits for AHN. Genetic predisposition played a role: rats bred for high aerobic response benefited more from exercise. These findings highlight that aerobic activities, especially sustained ones, can boost brain health by promoting new neuron growth in the hippocampus.

Engage in regular, sustained aerobic exercise, such as running, to support brain health and cognitive functions. While the study is on rats, its findings align with human research suggesting similar benefits. However, individual response to exercise can vary, so consult with a professional to tailor an exercise routine to your needs.
