Walking three times weekly increases brain volume and reverses age-related shrinkage

What was said

"In the walking group the group that was randomly assigned to walk three four times a week for 40 minutes compared to a stretching group who's still engaging in exercise but not cardiovascular exercise. The walking group their you know hippocamp is actually increased in volume by 1%. So you're changing the the brain, but you're also changing the behavior. Their memory was much better a year later."

Randomized controlled research demonstrates that cardiovascular exercise through walking reverses hippocampal atrophy that typically occurs at 1-2% per year after age 50. The hippocampus, critical for memory formation, actually grew in walkers while declining in the stretching control group, with corresponding improvements in memory performance.
