Many athletes train at higher altitudes immediately prior to an athletic competition. Select the scenario that correctly identifies how acclimatization to a higher elevation would improve endurance performance.
A. A hypoxic ventilatory response occurs that remains in place for a few weeks after returning to a lower altitude.
B. Increased ventilation at the higher altitudes will improve tidal volume when returning to the lower altitude.
C. Erythropoietin release will increase; consequently, the athlete will have a greater aerobic capacity when returning to the lower altitude.
D. Hemoglobin's affinity for oxygen will increase; therefore, tissues will receive more oxygen during exercise.
