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.

Training at altitude may help athletes gain a competitive edge at sea level; altitude exposure also presents problems to athletes, and these could possibly cancel out benefit. Even moderate altitudes can have a significant effect on athletic performance.Click to see the effects on physical performance at altitude.he âlowâ altitudes may not actually be at sea level, but could be 1250m, for example. However, the difference between the two altitudes is significant enough to have an effect on training [see the difference in oxygen and pressure at these altitudes with our high altitude calculator].
