Does exercise change brain structure?

Yes, exercise does change brain structure. The research discussed by experts highlights several significant ways in which exercise impacts the brain:

1. Neuron Growth: Exercise, particularly aerobic activities, leads to the growth of new neurons in the hippocampus, an area crucial for memory and learning. This growth counteracts decay often associated with aging and cognitive diseases like Alzheimer's 1.

2. Blood Flow: Increased blood flow to the brain during exercise delivers essential nutrients and oxygen, enhancing overall brain health and function 1.

3. BDNF (Brain-Derived Neurotrophic Factor) Increase: Exercise stimulates the production of BDNF, a protein that supports neuron survival, growth, and the formation of new memory circuits. Higher levels of BDNF are associated with improved cognitive functions and a lower risk of cognitive diseases 2.

4. Hippocampus Volume: Regular physical activity, like brisk walking, has been shown to increase the volume of the hippocampus in older adults. This structural growth is linked to improved memory functions and is instrumental in fighting age-related decline 3.
