Exercise for rheumatoid arthritis

Exercise can reduce pain and improve function in people with rheumatoid arthritis (RA). In addition, exercise may help prevent the buildup of scar tissue, which can lead to weakness and stiffness.¹ Exercise for arthritis takes three forms: stretching, strengthening, and conditioning.

Stretching involves moving joint and muscle groups through and slightly beyond their normal range of motion and holding them in position for 10 to 30 seconds. See illustrations of various stretches .

Strengthening involves moving muscles against some resistance. Studies have shown that moderate- or high-intensity strength training is well-tolerated in people with rheumatoid arthritis and can help increase or maintain muscle strength.¹ In addition, another study reports that a program of long-term, high-intensity weight-bearing exercises improves the functional ability, physical capacity, and emotional status of people with rheumatoid arthritis.² There are two types of strengthening exercises.

• Isometric strengthening is simply tightening a muscle or holding it against the resistance of gravity or an immovable object without moving the joint. For example:
  • Tighten the front thigh muscle of the leg or lift the leg off the floor while seated.
  • Push the wrist against the undersurface of a table.
• Isotonic strengthening means moving a joint through its range of motion against the resistance of a weight or gravity. For example:
  • Put a weight on your ankle and then bend and straighten your knee.
  • Lift free weights.

See illustrations of basic muscle-strengthening exercises and muscle-strengthening with free weights .

Conditioning exercise improves cardiovascular fitness. Conditioning can be achieved through a variety of methods, such as walking, biking, swimming, or water exercise. To get the most aerobic benefit from exercise, schedule 4 or 5 workouts each week that will bring your heart rate to 50% to 70% of its maximum for 20 to 30 minutes. You can calculate this target heart rate based on your age and your resting heart rate. Target heart rate is only a guide. Each individual is different, so pay attention to how you feel while exercising.

Note that even moderate activity, such as walking, can improve your health and may prevent disability from rheumatoid arthritis.

Be sure to follow your health professional's advice about your exercise program. For most people, physical activity does not pose any problem or hazard. For some people, some forms of physical activity might be unsafe or should be started only after talking with a health professional. See a list of exercise cautions to consider before beginning any exercise or fitness program.
