Официальное название
Appetite and Energy Intake in Young Female Adults During and After Simulated High-Altitude
Обзор
The goal of this clinical trial is to investigate the effects of acute passive continuous hypoxemia (simulated high-altitude at rest) on appetite and energy intake in healthy young female adults. The main questions it aims to answer are: * Does six hours of simulated high-altitude (5000 meters) reduce scores of subjective appetite and energy intake? * Do changes in appetite and energy intake persist in the hours following the end of hypoxic exposure? Researchers will compare the effects of simulated high-altitude to a control normoxia (sea-level) condition to see if exposure to low oxygen levels independently affect appetite and energy intake. Participants will: * Visit the laboratory for a preliminary screening session to assess eligibility. * Undergo two randomized, single-blind, experimental sessions consisting of six hours of passive exposure to normoxia or hypoxia in a climate-controlled chamber. * Consume foods provided from a curated list, served in ad libitum quantities, after leaving the laboratory to assess post-exposure energy intake.

- Другое Normoxia
Participants will undergo a 6-hour passive exposure to normoxia in a climate-controlled environmental chamber maintained at 22°C with 30% relative humidity. They will remain in a fasted state throughout the exposure period. - Другое Hypoxia (simulated altitude of 5000 meters above sea-level)
Participants will undergo a 6-hour passive exposure to a simulated altitude of 5000 meters above sea-level in a climate-controlled environmental chamber maintained at 22°C with 30% relative humidity. They will remain in a fasted state throughout the exposure period.
