Why Mobility Changes With Age As we get older, several things happen at once. Muscle mass and strength gradually decline, a process that accelerates if we become less active. Joints lose some of their natural lubrication and the surrounding tissue becomes less elastic. Balance and coordination systems, which rely on input from muscles, joints, and the inner ear, become less finely tuned.
None of this happens overnight, and none of it happens at a fixed rate for everyone. The research is clear that a sedentary lifestyle speeds these changes up considerably, while regular, appropriate exercise can slow them down, and in some cases partially reverse them. |
