As researchers learn more about how exercise fights chronic ills like heart disease and diabetes, doctors may soon be able to treat physical activity as the powerful medicine it is.
Exercise is good for you. That’s hardly news: People who exercise tend to have longer, healthier lives. But until recently, researchers have tallied its benefits only in narrow slices: Exercise lowers your cholesterol and blood pressure; it keeps you from getting fat. Now it’s becoming clear that those known slices don’t add up to the full pie.
The muscle-building aspects of exercise also help reverse a key change associated with aging: a decline in the function of mitochondria, our cells’ energy generators. This decline, often seen in sedentary individuals, can leave the mitochondria unable to completely burn the cellular fuel and that can lead cells to generate more oxidants, the oxygen-rich, reactive molecules that damage proteins and DNA.
