Physiological Function in Low Oxygen Environment
Rapid Acclimatization to Hypoxia at Altitude
In low oxygen environments, such as altitude, some adults may become ill and suffer from acute mountain sickness. Further, all adults will find that exercising becomes much more difficult when compared with exercise at lower…
