3 ) short-term , water-based aerobic capacity training , which results show limited evidence for a positive effect on functional ability and aerobic capacity .
( 4 ) long-term , l and -based aerobic capacity and muscle strength training , which results show moderate evidence for a positive effect on aerobic capacity and muscle strength .
With respect to safety , no deleterious effects were found in any of the included studies .
Based on the evidence , aerobic capacity training combined with muscle strength training is recommended as routine practice in patients with RA
BACKGROUND An up-to- date overview of the effectiveness and safety of dynamic exercise therapy ( exercise therapy with a sufficient intensity , duration , and frequency to establish improvement in aerobic capacity and /or muscle strength ) is lacking .
OBJECTIVES To assess the effectiveness and safety of short-term ( < three months ) and long-term ( > three months ) dynamic exercise therapy programs ( aerobic capacity and /or muscle strength training ) , either l and or water-based , for people with RA .
To do this we up date d a previous Cochrane review ( van den Ende 1998 ) and made categories for the different forms of dynamic exercise programs .
Effect of 8 wk of bicycle training on the immune system of patients with rheumatoid arthritis.
The effect of 8 wk of progressive bicycle training on the immune system was evaluated in a controlled study on 18 patients with rheumatoid arthritis and moderate disease activity .  Maximal O2 uptake increased significantly , whereas heart rate at stage 2 and rate of perceived exertion decreased significantly , in the training group compared with the controls . Resting levels of a number of immune parameters were measured before and after 4 and 8 wk of training . Training did not induce changes in blood mononuclear cell sub population s , proliferative response , or natural killer cell activity . Furthermore the plasma concentrations of interleukin-1 alpha , interleukin-1 beta , and interleukin-6 did not change in response to training . It is concluded that 8 wk of bicycle training does not influence the immune system of patients with rheumatoid arthritis
