why is training at high altitudes an advantage for athletes
Altitude training Depending very much on the protocols used, the body may acclimate to the relative lack of oxygen in one or more ways such as increasing the mass of red blood cells and hemoglobin, or altering muscle metabolism.[3][4][5][6] Proponents claim that when such athletes travel to competitions at lower altitudes they will still have a higher concentration of red blood cells for 10â€“14 days, and this gives them a competitive advantage. Some athletes live permanently at high altitude, only returning to sea level to compete, but their training may suffer due to less available oxygen for workouts.
