Heliox and breathing control during exercise
Part of Lungs & breathing clinical trials.
This trial tests whether a special gas mixture called heliox (helium and oxygen) can help control breathing during exercise. It is for healthy, active adults age 18–40 who exercise regularly and have no major health problems.
Summary written for real people, not researchers, by Clin2.

This study looks at how the temperature of the air you breathe affects your breathing control. You'll do some breathing tests in different temperatures to see how your body responds.
This trial studies a breathing-focused treatment to help people with HFpEF (a type of heart failure) feel and function better. It may help improve daily activity by addressing breathing limits that commonly come with this condition.
This study tests whether a breathing muscle training program (using an app) can improve endurance in healthy cyclists and triathletes. If you are a competitive road cyclist or triathlete, this might help you learn more about your breathing and performance.
This trial tests whether a special breathing device that helps you breathe during exercise can help you walk or pedal longer without getting out of breath. It is for people with severe COPD who have high carbon dioxide levels in their blood or who get very tired during 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.
This study tests whether breathing in molecular hydrogen before exercise affects how your body uses energy during physical activity. Researchers want to see if this simple intervention might improve exercise performance or recovery in healthy women.
