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 .
Moderately intensive exercise in a temperate pool for patients with rheumatoid arthritis: a randomized controlled study.
OBJECTIVES The aim of this study was to evaluate the effects of moderately intensive pool exercise therapy on patients with rheumatoid arthritis ( RA ) . METHODS Forty-six patients with chronic RA were r and omly assigned to a treatment group and a control group . The treatment group ( n = 20 ) exercised in a temperate pool twice a week for 12 weeks . The control group ( n = 23 ) continued with their previous activities .  Aerobic capacity , measured by means of a submaximum bicycle test , and the physical component of the SF-36 were chosen as the primary outcome measures . Two tests of muscle endurance were chosen as the secondary outcome measure . Additional functional tests and instruments were included . RESULTS No significant differences between the groups were found for the primary outcome measures . Significant improvements in the following aspects of muscular function ( P < 0.05 ) were found in the treatment group when their performance was compared with that of the control group : isometric shoulder endurance , grip force , dynamic endurance of lower extremities ( chair test ) and muscle function of lower extremities . Significant improvements were also found for vitality ( SF-36 ) compared with the control group . The improvements in the training group were maintained for 3 months . CONCLUSIONS Pool exercise therapy of moderate intensity significantly improved muscle endurance in the upper and lower extremities in patients with RA , while no impact on aerobic capacity was found . However , the study population was small and there is a need for further studies with larger population
