What the trial is, and whether it could suit you
The goal of this clinical trial is to compare physical ability of patients with transfusion-dependent β-thalassemia to control subjects. The main question it aims to answer is:
is there a difference in power output at first lactate threshold between patients with transfusion-dependent β-thalassemia and control subjects during maximal incremental exercise test.
Participants will have to realise differents exams including measurement of body compposition, maximal incremental exercise test, vertical jump, vasoreactivity test, blood sampling, quality of life questionnaires and neuromuscular assessments.
