My doctor keeps telling me about how important exercise is for my arthritis. What does exercise really do for this problem?
Exercise keeps joints from becoming stiff from a lack of movement. Exercise also strengthens the muscles around the joints. This gives the joints better support. Swimming or pool programs can improve aerobic fitness without stressing the joints. Low-intensity aerobic exercise can also cause the release of chemicals in the body. The chemicals act as natural pain relievers.
Arthritis medications can have many negative side effects. Exercise can help reduce the use of medications. Exercise can help patients lose weight. Fewer pounds means less stress on the joints. Exercise to improve balance and coordination can help prevent falls and fractures.
Osteoarthritis without exercise can become a vicious cycle. For example loss of joint motion causes changes in the way you walk. The forces through the joint change slightly. Over time repeated microtrauma from too much or uneven joint loading causes joint pain. Swelling and painful muscle spasms can also occur.
In general, exercise has many other positive health benefits. It improves mood and mental health; and prevents conditions such as diabetes, osteoporosis, and heart disease.
