Why would athletes in aerobic sports benefit by training at high altitude? What will be an ideal response?
ANSWER: While at high altitude, the body goes through acclimatization. Their hypoxic blood stimulates
the kidneys to secrete erythropoietin which leads to increased levels of red blood cells. At
altitude, these red blood cells are necessary to carry sufficient oxygen levels. However, these
additional red blood cells will benefit the athlete by allowing them to carry more oxygen to
their muscles when they compete.
