Study of High-Intensity Interval Training with Digital Coaching for Adults with Axial Spondyloarthritis to Improve Health and Exercise Adherence

What this Trial Is About

Researchers are studying the effects of high-intensity interval training HIIT on adults diagnosed with axial spondyloarthritis SpA, a group of inflammatory diseases affecting the spine and joints. This randomized controlled trial aims to compare HIIT with usual exercise routines to understand its impact on physiological health, inflammation, and self-reported disease activity. The study also explores adherence to exercise recommendations and how digital coaching may support sustainable high-intensity training. Participants will be randomly assigned to either an intervention group or a control group. The intervention group will do three training sessions per week for three months, including two HIIT sessions with coaching from a physiotherapist and digital support via a fitness watch and app. After this, they will continue with self-selected high-intensity training for nine months with monthly coaching contacts. The control group will maintain their usual exercise habits over 12 months. Throughout the study, participants will undergo assessments at the start, after three months, and after one year. These include physical fitness tests like aerobic capacity and grip strength, blood tests for inflammatory biomarkers, body composition measurements, and self-reported questionnaires on health status, pain, fatigue, and confidence in managing their condition. Continuous monitoring of heart rate during training and coaching support will help track adherence and intensity. The primary outcomes focus on disease activity and inflammatory markers, while secondary outcomes include physical function and well-being.
