It plans to enroll 90 participants, including those with primary mitochondrial disease and healthy volunteers.","completed","Studying Exercise in Mitochondrial Disease","This study is looking at different ways to help people with mitochondrial diseases. It compares standard exercise (like riding a stationary bike) with \"passive exercise\" methods, where a device moves your body for you. These passive exercise methods include the pGz Bed and Gentle Jogger, which use gentle, periodic movements. The study also uses an Exercise Pedal for in-bed exercise. Researchers will use a contrast agent called Lumason® during vascular ultrasounds to see how these exercises affect your blood vessels. The main goals are to understand how much oxygen your body uses during exercise and how oxygen is delivered to your tissues. You might be able to join if you are between 10 and 60 years old. The study is currently unclear on its recruitment status and plans to enroll 90 participants.","Oxygen consumption is measured for 1 hour per study intervention, and blood draws occur over a total of 4 15-minute periods.",132,"You would have 3 study visits, each involving a different exercise intervention (Cardiopulmonary Exercise Testing, pGz Bed, or Gentle Jogger). Each visit includes blood draws, a vascular ultrasound with Lumason® contrast, and an MRI of your leg.","Not stated in the trial record.",[41,45,50],"v2"]
