Key result
Brief exposure to intermittent hypoxia (eight 4-minute bouts at 80% oxygen saturation) increased erythropoietin levels in older adults.
Why the study?
It was unknown whether the shortest intermittent hypoxia protocol shown to increase erythropoietin levels in young adults would also increase erythropoietin levels in older adults.
Does an intermittent hypoxia protocol increase erythropoietin levels in older adults?
Does an intermittent hypoxia protocol increase erythropoietin levels in older adults?
Brief exposure to intermittent hypoxia increases erythropoietin levels in older adults, potentially offering a non-pharmacological method to increase oxygen-carrying capacity in this population.

Hypothesis-generating for intermittent hypoxia to raise erythropoietin in older adults; prospective trials needed before clinical adoption.
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.
