Effect of Acute Exposure to Moderate Altitude on Muscle Power: Hypobaric Hypoxia vs. Normobaric Hypoxia
When ascending to a higher altitude, changes in air density and oxygen levels affect the way in which explosive actions are executed. This study was designed to compare the effects of acute exposure to real or simulated moderate hypoxia on the dynamics of the force-velocity relationship observed in bench press exercise. Twenty-eight combat sports athletes were assigned to two groups and assesse...
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 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 ...
متن کاملPoint: 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 کاملAcute mountain sickness, chemosensitivity, and cardiorespiratory responses in humans exposed to hypobaric and normobaric hypoxia.
We examined the control of breathing, cardiorespiratory effects, and the incidence of acute mountain sickness (AMS) in humans exposed to hypobaric hypoxia (HH) and normobaric hypoxia (NH), and under two control conditions [hypobaric normoxia (HN) and normobaric normoxia (NN)]. Exposures were 6 h in duration, and separated by 2 wk between hypoxic exposures and 1 wk between normoxic exposures. Be...
