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.
Athletes who participate in endurance sports may benefit from training at altitude. By training in high altitudes with lower oxygen levels, athletes can increase their endurance when back on lower ground. Altitude training is a way of encouraging the body to produce more red blood cells. Altitude training may help prevent a person from acquiring altitude sickness during a hike. Altitude training is typically performed at about 8,000 feet above sea level. Andy Schleck during stage 1 of the 2009 Tour de France. 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. The ‘low’ 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]. Altitude training, sometimes called an altitude camp, is a way of encouraging the body to produce more red blood cells, which can improve endurance when performing activities at lower altitudes. Altitude training may help prevent a person from acquiring altitude sickness during a hike. Altitude training is typically performed at about 8,000 feet above sea level. Altitude training, also known as hypoxic training, involves exercising in, living in or otherwise breathing oxygen reduced air for the purpose of improved athletic performance, pre-acclimatization to altitude and/or physical wellness. Through the production of normobaric hypoxic (oxygen reduced) air, we can simulate altitudes of up to 21,000ft/6,400m. As a result, athletes, fitness enthusiasts and health conscious individuals worldwide can take advantage of the benefits associated with altitude training while at sea-level. Altitude training can be simulated through use of an altitude simulation tent, altitude simulation room, or mask-based hypoxicator system where the barometric pressure is kept the same, but the oxygen content is reduced which also reduces the partial pressure of oxygen. Altitude 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. Regardless of altitude, air is composed of 21% oxygen and 78% nitro Why altitude training works. Athletes from many sports have used altitude training to prepare for a big match or event, and not just when the event will be at a high altitude. They do this because the air is thinner at high altitudes meaning there are fewer oxygen molecules per volume of air.  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. Altitude 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. Regardless of altitude, air is composed of 21% oxygen and 78% nitrogen noun. 1  training performed at high altitude to prepare an athlete's body to cope with a reduced supply of oxygen ⇒ ■ Altitude training is another tried-and-tested training strategy for many an elite endurance runner. , ⇒ ■ I've never done altitude training before so it will be interesting to see what effect it has on me.  altitude training. training at real or simulated altitude sufficient to reduce oxygen partial pressure (PO 2) significantly below that at sea level, undertaken with a view to increasing haematocrit and so oxygen-carrying capacity of the blood, and thus enhancing sea-level aerobic performance.
