Effects of Normobaric Hypoxia and Different Exercise Modes on Blood Glucose Regulation in Overweight Adults

In the present randomized, single-blind, cross-over study, participants will be exposed to moderate hypoxia (oxygen level 16.5%) during three different exercises (low-intensity cycling, sprint interval and functional exercises). Participants will be randomly assigned to each exercise condition (computer-generated randomization plan), separated by a washout period (5-7 days). To accomplish this, participants will exercise in an environmental chamber in which oxygen concentration of the ambient air and, as such, oxygen levels can be closely controlled and monitored. Participants are required to attend the laboratory 8 times. These visits are including pre-exercise screening, baseline blood sampling, body composition screening and exercise in altitude conditions.
