Altitude training is the practice by some endurance athletes of training for several weeks at high altitude, preferably over 2,400 metres (8,000 ft) above sea level, though more commonly at intermediate altitudes due to the shortage of suitable high-altitude locations.ltitude training works because of the difference in atmospheric pressure between sea level and high altitude. At sea level, air is denser and there are more molecules of gas per litre of air.
What is altitude sickness? Altitude sickness is a condition resulting from a lack of oxygen, caused by low oxygen pressure at high altitudes. Well over half of those who travel from sea level to an altitude of 3,500m (11,500 feet) will experience symptoms of altitude sickness or acute mountain sickness. Almost all of those who ascend rapidly to 5,000m (16,500 feet) or higher will have some symptoms. The key word is 'rapidly'.
