Researchers have discovered an important mechanism that explains why physical activity can improve aging muscles. As we age, a certain gene called DEAF1 becomes overactive. This gene impairs the ability of muscles to break down damaged proteins and repair themselves.
Regular exercise reduces this disruption. This allows older people's muscles to renew more effectively and regain their strength. The research shows that walking, cycling, or other forms of moderate exercise directly contribute to maintaining muscle health.
It is important to know that the benefits of exercise may be reduced if the immune system in the muscles is compromised too much. Therefore, it is advisable to be physically active early and regularly before the muscles deteriorate too much.
This discovery supports the advice to stay active later in life. Healthy muscles are essential for mobility and independence over the years.
