NCT ID NCT02790541
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) can improve blood flow, brain function, and physical fitness in healthy adults aged 65 and older. Researchers measured changes in brain blood vessels, cognitive test scores, and exercise capacity over 6 months. The goal was to see if this therapy could counter some effects of aging.
