Figure 1

Schematic of experimental timeline. Subjects were exposed to 8 h of normobaric normoxia, normobaric hypoxia, or hypobaric hypoxia. Various physiological measurements were made before, throughout, and after testing. The ESQ and LLS were administered before exposure, 3 times over the exposure period, and after exposure.
