RA-HIIT: High-intensity Interval Exercise in Rheumatoid Arthritis
Study Details
Study Description
Brief Summary
Cardiovascular performance and overall fitness can be improved by high-intensity aerobic activity, and these benefits may be achievable by persons with rheumatic diseases. The investigators hypothesize that a 12-week high-intensity interval exercise program will provide substantial improvements in cardiovascular function, inflammation and symptoms affecting quality of life.

Experimental: Intervention group Cardiorespiratory and strength exercise training 2-3 sessions per week |
Behavioral: High intensity exercise
Twelve weeks of supervised high intensity aerobic and resistance exercise including two sessions/week, one additional session of the patient´s own choice, non-supervised. The target of the high intensity intervals (HIIT) is 90%-95% of maximum heart rate alternated with recovery phases at 70% of maximal heart rate. The resistance exercise session of large muscle groups: 8-10 repetitions, 2-3 sets.
Exercise guidance follows principles of self-efficacy and person-centeredness.
