Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Irisin is a myokine secreted by skeletal muscle through the cleavage of the membrane protein fibronectin type III domain-containing protein 5 (FNDC-5). Irisin is considered a mediator of exercise-induced metabolic benefits and has been shown to exert protective effects in several non-metabolic diseases. At the molecular level, irisin contributes to increased energy expenditure and metabolic regulation by promoting the browning of white adipose tissue. Previous studies have demonstrated that serum irisin levels increase following exercise.
Studies evaluating the role of irisin in ankylosing spondylitis have reported lower serum irisin levels in patients with more severe disease manifestations. However, no studies investigating the effects of exercise therapy on serum irisin levels in patients with axial spondyloarthritis have been identified in the literature. Previous research has focused on the relationship between disease severity and serum irisin levels, as well as the association between serum irisin levels and cardiovascular disease in patients with ankylosing spondylitis. Overall, low serum irisin levels are thought to be indicative of subclinical atherosclerosis, increased cardiovascular risk, and more severe disease. Evaluating the relationship between serum irisin levels and exercise in patients with axial spondyloarthritis may provide important contributions to disease management and follow-up. Therefore, the present study aimed to investigate the effects of high-intensity intermittent exercise and moderate-intensity continuous exercise on serum irisin levels, disease activity, functional status, and quality of life in patients with axial spondyloarthritis.

Study Groups

high-intensity exercise
Patients in this group will receive information and education about their condition and will be instructed to continue their current medical treatment and attend follow-up appointments regularly. Additionally, this group will undergo a high-intensity interval training (HIIT) program with a physiotherapist for 40 sessions in total, 5 sessions per week for 8 weeks, each lasting 35 minutes. Patients will work at 80% to 100% of their maximum heart rate. The first 4 weeks will be at 80% of maximum heart rate, followed by 85%, 90%, 95%, and finally 100%. This protocol will consist of 4 active periods of 4 minutes each at 80% to 100% of maximum heart rate (percentage to be determined weekly) and 3 rest periods of 3 minutes each at 60-70% of maximum heart rate (4x4 minutes). Each session will include a 5-minute warm-up before HIIT and a 5-minute cool-down after HIIT, for a total exercise time of 35 minutes.
High-Intensity Interval Training

Each session will include a 5-minute warm-up before HIIT and a 5-minute cool-down after HIIT, for a total exercise time of 35 minutes.
moderate intensity exercise
Patients in this group will receive information and education about their condition and will be instructed to continue their current medical treatment and attend regular follow-up appointments. Additionally, these patients will undergo a 40-minute, 5-session, 40-minute moderate-intensity continuous exercise (MCIT) program with a physiotherapist over 8 weeks. Patients will exercise at 50-70% of their maximum heart rate and with an RPE of 11-13 for 30 minutes. Each session will include a 5-minute warm-up before MCIT and a 5-minute cool-down after MCIT, for a total exercise duration of 40 minutes.
Moderate-Intensity Continuous Exercise
Patients will be trained for 30 minutes at 50% to 70% of their maximum heart rate and with an RPE of 11-13. Each session will include a 5-minute warm-up before MCIT and a 5-minute cool-down after MCIT, for a total exercise time of 40 minutes.
