According to research in the The Proceedings of the National Academy of Sciences, exercise can reduce and even stop common characteristics of aging from graying hair to muscle atrophy and shrinking brains. The key seems to be cell's mitochondria. If you'll recall from your high school biology, mitochondria are the power house of the cell, creating energy by converting oxygen and glucose to ATP.
In a really sad experiment with mice who are genetically pre-programmed to age rapidly, unexercised mice began show signs of age by three months and were old and decrepit by 6 to 9 months and dead by one year old. In a second group, mice who exercised vigorously (the equivalent of an hour three times per week), showed no signs of aging.
The researchers were surprised by the magnitude of the impact that exercise had on the animals’ aging process, Dr. Tarnopolsky said. They had not expected that it would affect every tissue and bodily system studied.
It is still not clear how much exercise will yield such beneficial effects, but we have a pretty good idea. The guidelines from the American College of Sports Medicine stress at least 30 minutes of moderate intensity exercise 5 days per week for healthy adults to maintain their health a reduce the risk for chronic disease.
The good news about exercise and the human body is that it's never too late to start. Get out and walk 5 minutes and day and increase your activity level from there.
