Why exercise is good for your joints

- Synovial fluid lubricates the joint. Each joint in the body is surrounded by soft tissue, also known as the synovial membrane, that is capable of producing fluid. This fluid acts as a lubricant, enabling the bones at each joint to slide past one another in a smooth motion. During exercise, the circulation of this fluid is increased and, therefore, reduces any pain at the joint.
- Blood flow increases. During physical activity, our heart increases at a much faster pace. This results in an increase in blood circulation throughout the body, including at the joints. This exposes the synovial membrane to an increased and steady supply of both oxygen and nutrients.
- Joint-repair genes are switched on. This is a relatively unresearched area; however, studies have shown that genes play a significant role in joint repair, with these being activated by physical activity and joint movement.
- Cellular waste is removed. During exercise, a process called autophagy is triggered. Autophagy refers to the biological process in which damaged cells are broken down and removed. The build-up of these cells at the joint can often cause severe pain and limits movement; therefore, ensuring these are removed can instantly decrease the pain experienced.
- Increase in muscle mass. It is no surprise that exercise strengthens muscles, ligaments, and tendons in the body; this includes those surrounding the joints. When these elements are strong, they behave like a brace, protecting the join from harm. Moreover, physical activity also increases your overall range of motion, enabling your joints to withstand more pressure.
