The research team isolated muscle tissue and focused on satellite cells - stem cells that live in skeletal muscle and regenerate muscle throughout adulthood.

These cells are activated continuously, but over time become fatigued and stop renewing. Endurance exercise increases proteins involved in quieting and activating these satellite cells, which enable self-renewal or differentiation.

Muscle maintenance is vital to ensure healthy ageing.

In research with mice, researchers found that aerobic exercise changed how the animals consumed oxygen, metabolised sugar, and how tired they were when they weren't exercising. The mice were leaner and had fewer signs of inflammati...
