Exercise for Your Brain

Wednesday, 06 Jun 2012 08:52 AM Current | Bio | Archive

The best way to prevent Alzheimer’s disease is to dedicate yourself to beating heart disease. Regular physical exercise is the key to keeping your heart healthy, and now research is showing the same exercise will keep your brain young.

Did you know that your brain shrinks as you age? It’s true. Following young adulthood, the hippocampus — the part of the brain that is involved with memory and spatial navigation — begins to get smaller.

A study published just a few months ago in the journal Proceedings of the National Academy of Sciences looked at 120 previously sedentary adults and the impact of exercise on their brains. Half the group was instructed to walk briskly around a track for 40 minutes, and the other half was put on a program that involved stretching and weights.

Stretching and weights had little impact on brain size, but the researchers found that the volume in their hippocampus actually increased in the group of walkers.

Those subjects also improved on spatial memory tests, and blood tests showed an increase of brain-derived neurotrophic factor, a chemical involved with learning and memory.

These findings make sense because, when you walk, you build up your cardiovascular system, and this results in an increase in oxygenated blood to the heart, which, in turn, is pumped to the brain.
