Point: Hypobaric hypoxia induces different physiological responses from normobaric hypoxia.
Hypoxia is defined as any combination of reduced barometric pressure (PB) and/or a reduced inspired fraction of oxygen (FIO2), which ultimately results in an inspired partial pressure of oxygen (PIO2) less than 150 mmHg (6). Pathophysiological responses to hypoxia or adaptations to hypoxic training can be investigated in two different types of exposure: hypobaric hypoxia (HH; FIO2 20.9%; PB 760...
متن کاملDiscerning normobaric and hypobaric hypoxia: significance of exposure duration.
TO THE EDITOR: We read a recently published article (4) with great interest. The authors performed a rigorously controlled study scrutinizing the possible differences in cardiorespiratory responses, control of breathing, and acute mountain sickness (AMS) incidence during short-term (6 h) exposures to hypobaric (HH) and normobaric hypoxia (NH). We commend the authors for their smart experimental...
متن کاملThe effects of nightly normobaric hypoxia and high intensity training under intermittent normobaric hypoxia on running economy and hemoglobin mass.
We investigated the effects of nightly intermittent exposure to hypoxia and of training during intermittent hypoxia on both erythropoiesis and running economy (RE), which is indicated by the oxygen cost during running at submaximal speeds. Twenty-five college long- and middle- distance runners [maximal oxygen uptake (Vo(2max)) 60.3 +/- 4.7 ml x kg(-1) x min(-1)] were randomly assigned to one of...

متن کاملAcute Mountain Sickness Symptoms Depend on Normobaric versus Hypobaric Hypoxia
Acute mountain sickness (AMS), characterized by headache, nausea, fatigue, and dizziness when unacclimatized individuals rapidly ascend to high altitude, is exacerbated by exercise and can be disabling. Although AMS is observed in both normobaric (NH) and hypobaric hypoxia (HH), recent evidence suggests that NH and HH produce different physiological responses. We evaluated whether AMS symptoms ...
