Type 1 Interferon Induced Changes to Exercise Adaptations in Systemic Lupus Erythematosus Patients (LUPEX)
Systemic Lupus Erythematosus, Interferon Deficiency
About this trial
This is an interventional basic science trial for Systemic Lupus Erythematosus focused on measuring Cardiac adaptations, Metabolic adaptations, High intensity interval training, Interleukin-6 signature, Tumor necrosis factor signature, Interferon signature

Arm 2
Experimental
No Intervention
Exercise
Non-Exercise
The patients will be randomized to 12-week supervised exercise training intervention or no exercise training. The exercise training program includes three supervised sessions per week over a 12-week period. The program consists of high intensity endurance training on ergometer bicycles. The intensity will progress throughout the 12 weeks of training. The training consists of 10 minutes of warm up at 40-60% maximum heart rate (HRmax), followed by 25 minutes of high intensity interval training (4 bouts of 4 min at >85% HRmax interspaced by 3 minutes of low intensity training at 40-60% Hrmax) and finally a 3-10 min cool-down of 50% Hrmax
Control group, therefore no supervised exercise regime. Subjects are asked to not increase habitual exercise routines.
