Recruiting studies
- NCT07164911Recruiting
Heart failure rehab: who benefits most?
This study looks at what helps people with heart failure get the most out of a cardiac rehab program. It aims to find out which patients improve the most after completing phase II cardiac rehab.
CorbieAges 40–75 - NCT07216755Recruiting
Breathing training and nitrate for altitude exercise
This study tests whether breathing training and a natural nitrate supplement (from beets) can improve how well you exercise in conditions that simulate high altitude. You'll do cycling workouts while we measure your performance.
Daytona Beach, FloridaAges 18–40 - NCT05468255Recruiting
Study how stopping exercise affects blood sugar and blood vessels
This study looks at what happens to blood sugar levels and blood vessel health when active adults stop exercising. It may help doctors understand how quickly these changes can happen and who may be most affected.
Norfolk, VirginiaAges Any age - NCT05818605Recruiting
Exercise training for people with hypertrophic heart muscle
This study tests whether a 24-week exercise program can improve exercise tolerance in people with hypertrophic cardiomyopathy (a thickened heart muscle). You may be asked to use phone-based tools and complete surveys during training.
San Francisco, CaliforniaAges 18–80 - NCT07207577Recruiting
Exercise and fatigue in beta-thalassemia
This study looks at why people with transfusion-dependent beta-thalassemia may feel tired or have trouble exercising. It compares patients with healthy volunteers matched by age and gender to understand the factors involved.
ChambéryAges 18 years+ - NCT05924555Recruiting
Exercise testing in inherited fatty acid breakdown disorders
This study checks how well people with long-chain fatty acid breakdown disorders tolerate exercise. It may help doctors better understand exercise limits and how to manage symptoms during activity.
Amsterdam, North HollandAges 18 years+ - NCT03775577Recruiting
Exercise testing study for people with heart failure
This study looks at exercise intolerance in heart failure, using heart and lung tests to understand how symptoms affect activity. It may help researchers better identify what limits exercise and how heart failure impacts quality of life.
Baltimore, MarylandAges 21 years+ - NCT06939153Recruiting
How age, sex, and exercise affect the heart when blood flow drops
This study looks at how your heart and blood vessels work together when blood flow to your legs is reduced using a special chamber. It compares younger and older adults, and men and women, especially after light exercise.
Boston, MassachusettsAges 18 years+ - NCT06786117Enrolling by invitation
Swallowing therapy study for sleep apnea patients
This study tests whether daily swallowing exercises can help people with sleep apnea who cannot tolerate CPAP therapy. It compares three groups: healthy people, successful CPAP users, and those who have difficulty using CPAP.
Cleveland, OhioAges 40–70 - NCT06366399Recruiting
Timing of resistance exercise for weight management
This study tests if doing resistance exercises (like lifting weights) in the morning or afternoon is better for weight management. You may qualify if you are between 50 and 74 years old, are overweight but generally healthy, and have not been very active with strength training.
Salt Lake City, UtahAges 50–74

Common questions
- Are there clinical trials for exercise intolerance?
- Yes. Clin2 currently lists 10 recruiting exercise intolerance studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a exercise intolerance trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a exercise intolerance trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
