About this study
Official title: Effects of Combined High-Intensity Aerobic Training and Resistance Training on Cardiovascular and Metabolic Health in Psoriatic Arthritis
The goal of this randomised controlled trial is to evaluate the effects of a 12-week intervention comprising high-intensity interval aerobic training and strength training on cardiovascular function, metabolic health profile and inflammation in patients with Psoriatic arthritis. A secondary goal is to assess the intervention´s impact on physical fitness, pain, fatigue, and health-related quality of life, and to explore long-term maintenance of exercise following completion of the intervention. We hypothesize that 12 weeks of combined high-intensity interval aerobic training and strength training will improve cardiometabolic health, inflammation, and enhance physical fitness, fatigue, pain and quality of life in Psoriatic arthritis.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Exercise programBehavioural
The exercise program includes two supervised sessions per week combining high-intensity interval training and strength training, plus one additional non-supervised aerobic session. The target of the high intensity intervals is 90%-95% of heart rate maximum. The strength training of major muscle groups includes 2-3 sets of 8-10 repetitions.
| Study group | Role | What they receive |
|---|---|---|
| Exercise group | Experimental | Cardiorespiratory and strength training, 2-3 sessions per week for a total of 12 weeks. Receives: Behavioral: Exercise program |
| Control group | No intervention | Care as usual, plus individualized counseling for health-promoting physical activity |
