Altitude training involves training at high elevations, typically above 2,400 meters (about 7,874 feet), where the air has lower oxygen levels. This reduced oxygen availability forces the body to adapt by producing more red blood cells, which can enhance endurance and performance when returning to lower altitudes. Athletes, especially in sports like running and cycling, often use altitude training to improve their aerobic capacity. The benefits can include increased stamina and better overall performance during competitions. However, it is essential to allow time for the body to acclimatize to avoid altitude sickness.
