Study: Walking can enlarge part of brain linked to memory

By Nick Katsarelas

A landmark study is reporting that walking can enlarge a part of the brain tied to memory.

The study is good news to people aged 55 and older. This is the age at which the hippocampus, a part of the brain linked to memory, begins to shrink. It's known that the hippocampus shrinks 1 to 2 percent a year with advancing age, contributing to memory loss and dementia risk.

In the study, published in The Proceedings of the National Academy of Sciences, 120 healthy but sedentary men and women (average age, mid-60s), were randomly assigned to one of two groups: the first walked 40 minutes a day, three days a week. The other participated in less aerobic exercises, like yoga and resistance training with bands.

After a year, brain scans showed that among the walkers, the hippocampus had increased in volume by about 2 percent on average; in the others, it had declined by about 1.4 percent.

So if you want to improve your memory, it sounds like you need two things: NUTRILITE® MEMORY BUILDERTM with Ginkgo, which supports your memory, learning, concentration, and endurance.

And a good pair of shoes.
