Recruiting studies
- NCT05769140Recruiting
Study how high altitude affects heart and breathing measures
This study looks at how exposure to high altitude changes measurements related to your heart and breathing. It may help scientists better understand health effects of altitude so they can improve safety and care.
Courmayeur, AostaAges 18 years+ - NCT07118462RecruitingPhase 4
Acetazolamide, high altitude, and plasma volume study
This trial tests how acetazolamide affects your body's fluid levels at high altitude. It might help understand if the drug can prevent altitude sickness.
BishkekAges 18–44 - NCT07193771Recruiting
Altitude and Outcomes in Children with ARDS
This study looks at how elevation (altitude) affects the recovery of children with a serious lung condition called ARDS who are on a breathing machine in the intensive care unit.
Sucre, Chuquisaca DepartmentAges 1 month–18 years - NCT02391519Recruiting
Study how high altitude affects body energy signaling
This study compares how the body responds to high altitude around the time of a planned C-section, including a signal involved in energy use. It may help researchers understand why pregnancy and blood-vessel function can differ at higher elevations.
Aurora, ColoradoAges 18–45 - NCT06686693RecruitingPhase 4
IV iron and exercise at high altitude
This study tests whether giving iron through a vein helps you perform better at high altitude. It may help you if you are a healthy adult who exercises regularly.
Natick, MassachusettsAges 18–40 - NCT07612956Recruiting
High-altitude training effects on teenage rowers' performance
This study tests whether training at high altitude for 4 weeks helps teenage male rowers improve their sport performance, fitness, and heart and lung health. Researchers will measure changes in body composition, rowing ability, and how well your heart and lungs work.
Macao, MacaoAges 12–19 - NCT07664462Recruiting
Heat and Altitude: Male Exercise Study
This study tests how your body handles working in heat when you are also at a simulated high altitude. The results could help understand physical limits and safety in jobs or sports.
Ottawa, OntarioAges 18–70 - NCT07718009Recruiting
Alternating versus fixed altitude training for elite race walkers
This study compares two types of altitude training for elite race walkers: training at a fixed high altitude versus alternating between different altitudes. It aims to see which method better improves exercise capacity and how the body adapts.
MacaoAges 18–26 - NCT06596083Recruiting
Ketone supplement and altitude training study
This study tests whether drinking a ketone supplement helps your body adapt better during a 5-week altitude training program. You would live at high altitude but train at low altitude.
Leuven, Vlaams-BrabantAges 18–35 - NCT05804448Recruiting
Altitude effect on spinal headache after C-section
This study looks at whether living at higher or lower altitudes changes the risk of a specific headache after a C-section done with spinal anesthesia. The goal is to understand who is more likely to get this headache so care can be better tailored.
Jumla, KarnaliAges 18 years+ - NCT06930027Enrolling by invitation
Low-oxygen training for ice hockey players
This study tests whether training in a low-oxygen environment (hypoxia) can boost strength and power in ice hockey players. Researchers want to see if it helps improve your explosive movements and muscle function.
Katowice, Silesian VoivodeshipAges 18–35 - 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

Common questions
- Are there clinical trials for high altitude effects?
- Yes. Clin2 currently lists 12 recruiting high altitude effects 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 high altitude effects 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 high altitude effects 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.
