揭開高原訓練的面紗

In 1968, when the Summer Olympic Games were scheduled to be held in Mexico City, at an altitude of 2,300 meters above sea level, considerable attention was directed at the questions of how altitude would affect exercise performance. During the preparation for the Mexico City Olympics, many concerns existed about the possible beneficial effects of the lower pressure and air resistance at the altitude for events involving speed and power; and the possible detrimental effects of the reduced oxygen at the altitude for the endurance events. What are the acute physiologic responses to altitude? Can altitude training improve endurance performance at sea level? All such questions would be explored in this article.
