Exercise has many benefits for the body and metabolism. Researchers have now learned more about a protein that appears to play an important role in this: sirtuin 1. This protein helps cells function better and could potentially explain some of the health benefits of physical activity.
Sirtuin 1 was initially discovered as a substance that can switch genes on or off. It has since proven to be a versatile protein that influences all kinds of processes in the body. Scientists are studying it intensively to better understand how the body responds to, for example, exercise and physical activity.
It is difficult to say precisely which changes caused by exercise are the most important. After all, a great deal happens simultaneously in our bodies when we are active. Even so, sirtuin 1 appears to play a key role in improving metabolism, which allows, for example, energy to be used more effectively.
This knowledge can help to gain more insight into healthy ageing. By keeping the body and cells active, functioning remains better. Exercise can thus contribute to a healthier and longer lifespan.
