A proposal was made to help achieve greater results in sports by letting the athlete breath in an atmosphere consisting of 50% oxygen. Do you expect revolutionary better sports results via this method of greater O2(g)

Step 1
Oxygen is essential for aerobic respiration, which produces the energy (ATP) muscles need during prolonged exercise. Increasing oxygen availability can potentially enhance endurance and delay fatigue. Show more…

The air at high altitude has a lower pO2 than air at sea level. Therefore, some competitive endurance athletes live at high altitudes to induce respiratory and hematopoietic adaptations (changes in blood components) that can improve performance at sea level. For example, within a few days at altitude, a person's normal ventilation rate will be 2-3 L/min higher than their sea level rate, and their blood will have more red blood cells and an increased level of 2,3-diphosphoglycerate, a substance produced by red blood cells that increases the P50 of hemoglobin. Explain why EACH of these physiological changes is necessary to acclimate to life at high altitudes, and speculate on how they could lead to improved performance of aerobic exercise at sea level (assuming that changes that occur at high altitudes will be maintained at sea level).
