Exercise Enhances the Cellular Maintenance Processes of Autophagy

How does exercise improve health over the long term and modestly extend healthspan? One of the important mechanisms is increased autophagy, the collection of cellular maintenance processes that are provoked into action by various stresses. Heat, lack of nutrients, and the oxidative molecules generated during the hard work of exercise are all sufficient to trigger greater autophagy for some period of time, continuing even after the stress has ended. This sort of stress response is an important component of near all of the methods demonstrated to somewhat slow aging in laboratory species. Sadly it isn’t anywhere near as effective at extending life span in longer-lived species such as our own. Nonetheless, the benefits of exercise are both highly reliable and essentially free. It would be foolish to skip them given that cost-benefit equation.

Researchers have found that a lack of muscle stimulus due to a surgically induced sciatic nerve injury in rats resulted in a buildup of inadequately processed proteins in muscle cells and consequently led to muscle weakness or wasting. This buildup was caused by the impairment of autophagy, the cellular machinery responsible
