Arthritis is an inflammatory condition of the joint where your bones come together. Osteoarthritis is characterized by the thinning and break down of the cartilage which acts as a protective layer at the end of the bones.

Instead, it is considered as a disease of the joint with multiple potential factors.

Being overweight is associated with chronic low-grade inflammation throughout the body. By staying at a good weight, running allows your joints to be less susceptible to damaging inflammation. Furthermore, studies have shown that cartilage is subject to the “lose-it or use-it” principle, Rather than breaking down your joints, running helps to keep your joint lubricated and stimulates your body to build new cartilage. It was shown that the cartilage became more resilient as it adapts to the demand of running. Therefore, sedentary people are advised to exercise regularly for the same reasons.
