Breathing training plus exercise to improve breathing capacity
This study looks at whether breathing exercises combined with exercise training can improve how much and how well you can breathe during activity in people with non-cystic fibrosis bronchiectasis. It may help by improving breathing efficiency and exercise tolerance, but you must be stable and healthy enough to safely exercise.
Jacksonville, FloridaAges 21–80 - NCT05819931Recruiting

Common questions
- Are there clinical trials for breathing?
- Yes. Clin2 currently lists 354 recruiting breathing 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 breathing 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 breathing 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.
