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.
Huayna Potosi (6088m), Bolivia. Acclimatisation to altitude involves breathing faster & more deeply, and the heart pumping more blood to the brain & muscles.

You can demonstrate how important breathing harder is by using our high altitude oxygen calculator. Some people include breathlessness during exercise as a component of altitude sickness, but this is misleading.
