Repeated Bout Effect i Neuromuscular Diseases

This study examines whether people with neuromuscular diseases (conditions affecting muscle function) experience the same protective effect from repeated exercise that healthy people do — known as the 'repeated bout effect.' After a first round of intense exercise, healthy muscles are usually less damaged by a second round. Researchers want to know if this protection also applies to people with these conditions. You may be eligible if: - You are over 18 years old - You have a confirmed molecular diagnosis of a specific neuromuscular condition (or are a healthy control) - You are physically able to complete the exercise challenge - You do not have an active muscle injury on the test day You may NOT be eligible if: - You have heart or lung disease that makes peak exercise testing unsafe (NYHA class III-IV) - Your veins are too difficult to access for blood sampling - You have severe muscle weakness that prevents completing the exercise test Talk to your doctor to see if this trial is right for you.
