> IS IT POSSIBLE TO OUTRUN DEATH?
Researchers at Iowa State University have discovered that you can prolong your life through movement. In fact, it doesn’t matter whether you run for 10 minutes or half an hour—the most important thing is that you reach a speed of at least 5.5 miles per hour. The reward? Three extra years of life. But how is that possible? We need to move to maintain a healthy metabolism. For example, if you are not moving much, then you are not using much of the sugar (glucose) in your blood. That is problematic because the pancreas increases the production of insulin when the blood glucose levels rise. The consequence: Our cells get used to the insulin—and become resistant. Over time the cells no longer respond in a normal way to the action of insulin. It’s a condition that doctors classify as diabetes. But moving regularly not only keeps glucose levels on an even keel—it also increases muscle mass. And that, in turn, leads to a markedly higher life expectancy: An international team of researchers found that weak muscles can nearly double our risk of dying. Even overweight people have a longer life expectancy if their muscles are developed. Two studies recently published in British Medical Journal have shown that muscular strength is an accurate predictor of mortality— even after adjusting for other factors like heart health. For those with strong muscles, cardiovascular disease and cancer occur less often or later in life; their posture is better and they fall less.
