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.
Altitude exposure is not without its share of issues. During altitude training, athletes may experience decreased REM sleep. The hypoxic environment can hinder breathing for some, and significantly affect sleep, which could potentially decrease the athlete's rate of recovery.
