title: Changes in muscle fibre size and physical performance in patients with rheumatoid arthritis after 7 months physical training.
abstract: Ten patients with rheumatoid arthritis of moderate severity were given 7 months' physical training. During the investigation period the patiens improved their physical performance capacity as well as they lowered their rate of perceived exertion during submaximum exercise. There was a small increase in muscle fibre size and a correlation was found between muscle strength and type II fibre size. Clinical examination and X-ray studies did not reveal any further joint destruction during the investigation period.
