Recruiting studies
- NCT05684562Recruiting
Lung function and exercise capacity in Fontan patients
This study looks at how well the lungs and heart work together during exercise in people who have had the Fontan operation. The goal is to understand how lung function affects overall fitness, which can help improve care for Fontan patients.
AnkaraAges 8–55 - NCT05218083Recruiting
Mobile rehab program with interval exercise after COVID-19
This trial tests a coach-supported, phone-based rehabilitation program that includes high-intensity interval-style exercise for people recovering from COVID-19 after a hospital stay. It may help improve breathing, strength, and walking by providing structured exercise at home.
Birmingham, AlabamaAges 18 years+ - NCT05092126Recruiting
Testing a pre-surgery breathing and heart check tool
This study is developing and checking how well a pre-surgery evaluation system (using objective body measurements) can predict and help around the time of anesthesia and surgery. You might be asked to complete a clinic screening and provide consent, as long as your results fit their safety and screening thresholds.
Durham, North CarolinaAges 18 years+ - NCT04791371Recruiting
Study how fitness and insulin resistance relate to diabetes
This study looks at how low physical activity, insulin resistance in small blood vessels, and cardiorespiratory fitness connect to diabetes and blood sugar control. You may be eligible if you are generally sedentary and fit within the weight range, and if you do not have certain heart, lung, nerve, or medication factors.
Aurora, ColoradoAges 30–55 - NCT04765020RecruitingPhase 2/Phase 3
Fitness study for kids after cancer treatment
This study looks at how children and teens’ heart and fitness recover after cancer treatment. If you live in Krefeld and are at least 6 weeks past treatment, the study may offer a structured follow-up fitness assessment to see what helps recovery.
KrefeldAges 7–23 - NCT07804680Recruiting
Fitness and health in children with or without autism
This study looks at how fitness levels relate to body size and heart health in children and teens with or without autism. It uses existing medical records, so no new tests are needed.

Common questions
- Are there clinical trials for cardiorespiratory fitness?
- Yes. Clin2 currently lists 30 recruiting cardiorespiratory fitness 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 cardiorespiratory fitness 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 cardiorespiratory fitness 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.
