How Much Exercise Is Needed to Help Improve Thinking Skills?
We know that exercise may help improve thinking skills. But how much exercise? And for how long? To find the answers, researchers reviewed all of the studies where older adults were asked to exercise for at least four weeks and their tests of thinking and memory skills were compared to those of people who did not start a new exercise routine. The review is published in the online issue of Neurology® Clinical Practice. They found that people who exercised an average of at least 52 hours over about six months for about an hour each session may improve their thinking skills.
In contrast, people who exercised for an average of 34 hours over the same time period did not show any improvement in their thinking skills.
