Exercise Shown to Boost Brain Cell Growth, Improve Cognitive Function
New research published today, November 6, 2024, indicates that specific types of physical exercise can stimulate the growth of new brain cells – a process known as neurogenesis – and improve memory and overall cognitive function.
Neuroscientist Robert Lowe, specializing in Alzheimer’s treatment, explains that resistance training, dual-task exercises, and leg exercises are particularly effective. Resistance training, involving exercises like weight lifting and squats, boosts levels of Brain-Derived Neurotrophic Factor (BDNF), which encourages the birth of new neurons in areas crucial for learning and memory, such as the hippocampus. Maintaining cognitive health is increasingly important as global populations age.
Dual-task exercises, which combine physical activity with mental challenges – such as walking while conversing – simultaneously activate brain networks responsible for attention and coordination. These workouts are more effective at enhancing neurogenesis than either physical or cognitive training alone, according to neuroscience research. Leg exercises, including squats and brisk walking, engage large muscle groups and send biochemical signals to the brain, further supporting BDNF production and brain cell growth.

Researchers recommend incorporating all three exercise types into a routine, with resistance training two to three times weekly, daily dual-task activities, and consistent leg-focused workouts. Regular physical activity not only builds muscle but also creates an environment conducive to brain plasticity and resilience, potentially mitigating the risk of neurodegenerative diseases like Alzheimer’s disease.
Dr. Lowe emphasized the importance of consistent physical activity, stating that it improves blood flow, reduces inflammation, and supports cognitive function, and further studies are planned to explore the long-term effects of these exercise regimens.
