If you want to boost your brain power well into old age it appears not just your heart or waistline can benefit from lifelong exercise.
Researchers looked at thousands of kids starting at the age of 11. Over the years the children were asked about exercise as they took memory and learning tests. After 40-years, researchers determined regular exercise, at least 4 times a week, protects the brain and could help fight dementia.
The research published in the Journal Psychological Medicine shows men who exercised more than four times a week, lost a third less of their brain power by age 50, and women lost 25 percent less brain power.
Remember it is never too late to start exercising, it can be a brisk walk with the dog, whatever you can do to get your heart rate up and break a sweat. Even those who exercised once a week saw a boost, with the physical activity helping to slow their mental decline by an average of 10 percent.
