Live High, Train Low
Athletes or individuals who wish to gain a competitive edge for endurance events can take advantage of exercising at high altitude. High altitude is typically defined as any elevation above 1,500 metres (5,000 ft).
One suggestion for optimizing adaptations and maintaining performance is the live-high, train-low principle. This training idea involves living at higher altitudes in order to experience the physiological adaptations that occur, such as increased erythropoietin (EPO) levels, increased red blood cell levels, and higher VO2 max, while maintaining the same exercise intensity during training at sea level. Due to the environmental differences at high altitude, it may be necessary to decrease the intensity of workouts. Studies examining the live-high, train-low theory have produced varied results, which may be dependent on a variety of factors such as individual variability, time spent at high altitude, and the type of training program. For example, it has been shown that athletes performing primarily anaerobic activity do not necessarily benefit from altitude training as they do not rely on oxygen to fuel their performances.
Altitude training can produce increases in speed, strength, endurance, and recovery by maintaining altitude exposure for a significant period of time. A study using simulated altitude exposure for 18 days, yet training closer to sea-level, showed performance gains were still evident 15 days later.
Opponents of altitude training argue that an athlete's red blood cell concentration returns to normal levels within days of returning to sea level and that it is impossible to train at the same intensity that one could at sea level, reducing the training effect and wasting training time due to altitude sickness.

Famous quotes containing the words live and/or train:
“It was evident that, both on account of the feudal system and the aristocratic government, a private man was not worth so much in Canada as in the United States; and, if your wealth in any measure consists in manliness, in originality and independence, you had better stay here. How could a peaceable, freethinking man live neighbor to the Forty-ninth Regiment? A New-Englander would naturally be a bad citizen, probably a rebel, there,—certainly if he were already a rebel at home.”
—Henry David Thoreau (1817–1862)
“Still, I am prepared for this voyage, and for anything else you may care to mention.
Not that I am not afraid, but there is very little time left.
You have probably made travel arrangements, and know the feeling.
Suddenly, one morning, the little train arrives in the station, but oh, so big
It is! Much bigger and faster than anyone told you.”
—John Ashbery (b. 1927)
