Andy’s Quick Hits (166): Exercise improves memory in older adults

Yes, I know I have reported almost continuously on the positive effects of exercise on the brain!

This is not a new study but rather a meta-analysis, hot of the presses, of 36 studies (selected from over 1’200 studies) and is quite specific to give as much clarity as possible. Those critical scientists are always looking at flaws and need a lot of proof before they’re convinced. And convinced they should be.

This meta-analysis showed clearly that exercise helps episodic memory — i.e. memories of things that have happened in your life at different times — and is one of the first to deteriorate in older age.

What’s more they could also define just how much exercise you need which is three times a week (elevated heart rate for more than 20 minutes) for four months. The biggest impact is between the ages of 55 and 68. Note that this does not need to be intensive exercise.

Obviously other research has shown that exercise at any age is beneficial — so no excuse if you’re under 55!
