Recently, Nature Neuroscience published a review titled "Be smart, exercise your heart:exercise effects on brain and cognition" by Hillman et al. It is an excellent overview of the science of 'your brain on exercise'. The research that the group gathered is multi-disciplinary, including epidemiological, molecular, animal, and human studies. Some interesting findings include:
1. Aerobic capacity and academic achievement is positively correlated in school-age children.
2. In older adults, cognitive ability is greatly increased in response to aerobic exercise training. Even total brain volume increases with exercise!
3. Animal studies on exercising rodents show increased cell proliferation (division and growth) in the 'memory center' of the brain, known as the hippocampus.
Imagine a pharmaceutical company came out with this ad: New drug! Will increase brain power, decrease fat, improve emotional health, and add decades to your life.
The reality is even better: no prescription is required.
