Conclusion Exercises and PA promotion according to public health recommendations  for PA improved cardiovascular fitness , muscle strength and PA behaviour , with moderate effect sizes in people with SpA , RA and HOA/KOA .
Objective To evaluate the effectiveness of exercise and physical activity ( PA ) promotion on cardiovascular fitness , muscle strength , flexibility , neuromotor performance ( eg , balance ) and daily PA in people with rheumatoid arthritis ( RA ) , spondyloarthritis ( SpA ) and hip/knee osteoarthritis ( HOA/KOA ) .
Predictors of exercise and effects of exercise on symptoms, function, aerobic fitness, and disease outcomes of rheumatoid arthritis.
OBJECTIVE To determine the effects of participation in a low-impact aerobic exercise program on fatigue , pain , and depression ; to examine whether intervention groups compared with a control group differed on functional ( grip strength and walk time ) and disease activity ( total joint count , erythrocyte sedimentation rate , and C-reactive protein ) measures and aerobic fitness at the end of the intervention ; and to test which factors predicted exercise participation . METHODS A convenience sample of 220 adults with rheumatoid arthritis ( RA ) , ages 40 - 70 , was r and omized to 1 of 3 groups : class exercise , home exercise using a videotape , and control group . Measures were obtained at baseline ( T1 ) , after 6 weeks of exercise ( T2 ) , and after 12 weeks of exercise ( T3 ) . RESULTS Using structural equation modeling , overall symptoms ( latent variable for pain , fatigue , and depression ) decreased significantly at T3 ( P < 0.04 ) for the class exercise group compared with the control group . There were significant interaction effects of time and group for the functional measures of walk time and grip strength : the treatment groups improved more than the control group ( P < or= 0.005 ) . There were no significant increases in measures of disease activity . Fatigue and perceptions of benefits and barriers to exercise affected participants ' amount of exercise , supporting previous research . CONCLUSION This study supported the positive effects of exercise on walk time and grip strength , and demonstrated that fatigue and perceived benefits /barriers to exercise influenced exercise participation . Furthermore , overall symptoms of fatigue , pain , and depression were positively influenced in this selective group of patients with RA ages 40 - 70 years
