Abstract
We previously identified the shortest intermittent hypoxia protocol necessary to increase erythropoietin levels in young adults. The objective of this study was to determine whether the same intermittent hypoxia protocol increases erythropoietin levels in older adults. Eight 4-min bouts of hypoxia, representing a hypoxic duration of 32 min at a targeted oxygen saturation of 80%, increased erythropoietin levels in older adults, suggesting that exposure to intermittent hypoxia has the potential to increase oxygen-carrying capacity in an aging population.
