Travel to high altitude exposes the human body to a variety of stresses, the most prominent being reduced available oxygen with increase in altitude due to reduced partial pressure of oxygen. Several physiological responses are initiated in the human body to promote faster acclimatization to these adverse environmental conditions.

High Altitude: Physiology - PowerPoint PPT Presentation

For athletes, high altitude produces two contradictory effects on performance. For explosive events (sprints up to 400 metres, long jump, triple jump) the reduction in atmospheric pressure means there is less resistance from the atmosphere and the athlete's performance will generally be better at high altitude. For endurance events (races of 800 metres or more), the predominan… WebChapter 44 Aviation, High Altitude, and Space Physiology.
