Altitude exposure causes wide-ranging physiological responses. Changes occur in ventilation, heart rate, acid-base regulation, body composition, and substrate metabolism. The environment often increases exercise stress. Low oxygen pressure at high altitude can stress the oxygen transport systems of even the fittest athletes. Cold temperatures can numb the flesh and sometimes suppress cellular metabolism to dangerous levels. Hot temperatures can result in a competition for blood between the skin and muscles that can severely limit physical performance and subject the body to thermal injury. Smoggy air can leave the athlete gasping for air during exercise, while traveling across time zones can fatigue athletes and make them less able to compete. Through this paper, we pay particular attention to effects of those conditions on acute and long term exercise response and to acclimatization.
