Exercise-induced Improvements of Inflammatory Status in Patients With Rheumatoid Arthritis - Improvements of Cardiovascular Risk Factors and Quality of Life

The primary aim of the study is to investigate if 10 weeks of high intensity interval training improve inflammatory status in patients with rheumatoid arthritis.

Gedetailleerde beschrijving

Rheumatoid arthritis (RA) is a chronic, systemic inflammatory disorder that may affect many tissues and organs, but principally attacks synovial joints. Although the cause of rheumatoid arthritis is unknown, autoimmunity plays a role in both the chronicity and progression, and RA is considered as a systemic autoimmune disease.

Due to chronic inflammatory status, RA-patients are at higher risk of developing cardiovascular disease (CVD) compared to the general population. Accumulating evidence indicates that regular physical activity has beneficial effects on RA. The mechanisms behind exercise-induce improvements are none the less unclear and more research is needed to better understand the beneficial effects of exercise training in this patient group.

Recently, promising results from gene expression studies of blood cells have revealed unexplored fields of biomarker discovery and gene expression profiling of disease. Due to easy accessible and minimally invasive sample collection, gene expression profiling of whole blood might turn out to be a promising tool in molecular diagnostics and clinical medicine. To our knowledge, whole-genome transcriptional changes have not previously been studied in RA-patients undergoing a high-intensity exercise program.

Hypothesis: Ten weeks of high intensity interval training improves the inflammatory status, quality of life, and known risk factors for cardiovascular diseases.

In addition to measure traditionally inflammatory markers in the blood, whole genome analysis will be made.

Deelnemersgroep / Arm	Interventie / Behandeling
Experimenteel: Exercise then control	Gedragsmatig: high intensity interval training First 10 week of high intensity interval training, twice a week. The interval training session consists of 10 minutes warm up at 70 percent of maximal heart rate and continues with 4 times 4 minutes of high intensity intervals at 90 to 95 percent of maximal heart rate separated by 3 minutes of active brakes in between at 70 percent of maximal heart rate. Training will be performed by cycling. Training intensity will be supervised through the use of polar puls monitors and the BORG scale of subjective perceived exhaustion. Second 10 weeks participants are instructed not to change their dietary patterns or physical activity levels during the study period.
