"High Altitude Training" (document)

High Altitude Training involves exercising at elevations where the air contains less oxygen, typically above 2,000 meters (6,500 feet). This environmental change causes the body to adapt by producing more red blood cells, which improves oxygen delivery to muscles. Athletes often use this method to boost endurance and performance when they compete at lower altitudes. When they return to sea level, the increased red blood cell count can enhance physical capability, making their training more effective. It's a scientifically supported technique used by many endurance athletes to gain a competitive edge.
