Exercise For Brain Power
From The BLI Letter, Volume 3, Number 19
Presented by Rick Allen, DC
"Better health leads to better dancing."
The Better Life Institute (BLI), whom I greatly respect, provided this additional benefit of exercise in a recent newsletter. Dancing is a great form of exercise and help keeps our brain cells as well as our legs, in great shape. Hope you have better health and can dance for years to come. You can visit the BLI web site (http://www.blionline.com) for lots of other good advice.
One of the greatest fears people over 60 have is the fear of losing their memories and mental abilities. All of us think about being able to function well mentally as we get older; it just seems more relevant the closer we are to 60 or so. The recent BLI publication Growing Old Gracefully covers the basic diet and supplementation program necessary for sustaining mental abilities, as well as many other health issues. In addition, recent research has shown that exercise may be more important than ever to maintain brain power.
With magnetic resonance imaging (MRI), scientists can get an accurate picture of the inside of the body--in this case, specific regions of the brain. In comparing the white matter, gray matter, and other regions of the brain, they found that the quantity of brain matter appears to decline with age. That prompted scientists to look for differences in the decline in brain tissue in people 55 and older with different activity levels. What they found was that the greater the level of exercise, the less gray matter declined. It didn't stop the decline completely but after adjusting for other factors, those who exercised didn't just benefit physically, they also benefited mentally.
Exercise may help more than just gray matter. In another study, researchers examined memory, impaired glucose metabolism, and the hippocampal region of the brain, the area thought to be responsible for memory. They discovered a relationship between impaired glucose metabolism and a smaller hippocampal region. What does exercise have to do with glucose metabolism? Everything. Those who exercise regularly are better able to regulate blood sugar; therefore atrophy of the hippocampal region may not occur and memories may be retained longer.
Even though these are preliminary studies, it seems clear that regular exercise is important to retaining brain power as we age. You don't have to spend hours in the gym to get the benefits--a simple 30-45 minute walk every day is enough to get the benefits of exercise.
That's why we'll soon be adding a walking booklet to our current list of exercise aids--we want to help you physically and mentally. Look for the publication announcement soon at BLI Online
