Question

Maximal aerobic power decreases with high altitude due to the

a. lower PO2.
b. lower percent of oxygen in the air.
c. lower hemoglobin levels.
d. increase in hemoglobin levels.

Answer 1

Maximal aerobic power decreases with high altitude due to the lower percent of oxygen in the air. Hemoglobin saturation is lower at high altitudes compared to sea level.

Step-by-step explanation:

Maximal aerobic power decreases with high altitude due to the lower percent of oxygen in the air. An increase in altitude results in a decrease in atmospheric pressure, which makes it more difficult for the body to achieve the same level of oxygen saturation. Hemoglobin saturation is lower at high altitudes compared to sea level.
