LahoreAges 6–18 - NCT07261293Recruiting
Blood flow restriction exercise for COPD patients
This study tests whether adding mild blood flow restriction to aerobic exercise can improve lung function, exercise capacity, and inflammation in people with stable COPD. You would exercise on a bike or treadmill while wearing soft cuffs on your legs to lightly restrict blood flow.
IstanbulAges 40–80 - NCT06077019Recruiting
How lung function affects exercise in fit adults
This study looks at how your lung function may limit your exercise capacity, even if you are very active. If you are a healthy, highly fit adult aged 18-39, you may be able to help researchers better understand this connection.

Common questions
- Are there clinical trials for functional capacity?
- Yes. Clin2 currently lists 49 recruiting functional capacity 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 functional capacity 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 functional capacity 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.
