Exercises to Strengthen Joints
Aches and pains from degenerative joint disease--the arthritis associated with aging--can discourage many 40+ adults from exercising. Surprisingly, however, exercise is just what you need to overcome the stiffness and pain. The term arthritis, meaning "inflammation of a joint," refers to many conditions that can cause joint pain. As we age, the most common form of arthritis that occurs is osteoarthritis. It affects more than 21 million adult Americans, beginning on average at age 45. By age 65, more than 50 percent of the population has osteoarthritis in at least one joint. What Are the Causes?
Osteoarthritis may develop simply due to the normal wear and tear of the joints over the years. Other factors that may hasten the development of osteoarthritis include excess weight, poor posture, or even damage from a previous injury. Any of these conditions can cause the cartilage that covers the ends of the bones to soften and wear out, resulting in chronic irritation. In some cases, the cartilage wears away completely, exposing the underlying bone, and thickening of the ends of the bone may occur. Usually a person with osteoarthritis only has problems in the joints of their hips, knees, feet, and spine. Sometimes the pain can be relieved with rest, while other times, especially in the case of more serious symptoms, drugs may be needed to reduce the swelling. Only in very severe cases is surgery necessary to replace or repair the joints damaged by osteoarthritis. Next: Why Should You Exercise?
