The purpose of this study is to compare the effectiveness of a supervised high-intensity exercise programme followed by an unsupervised exercise programme to an unsupervised exercise programme in patients with Rheumatoid Arthritis.

Patients with Rheumatoid Arthritis are in general less fit and more at risk of comorbidities such as cardiovascular events compared with healthy age-matched controls. Studies indicates that patients with Rheumatoid Arthritis have a lower level of physical activity than the general population and a low proportion of patients with Rheumatoid Arthritis exercises. Regular exercise with moderate to high intensity level of intensity has proven to be effective in reducing the cardiovascular risk by improving cardiovascular fitness and to increase muscle strength. Therefore, it is of interest to investigate if supervised exercise programme makes a difference making patients with Rheumatoid Arthritis participate in exercise.
