What hematological adaptation is associated with altitude training?

What hematological adaptation is associated with altitude training?

• A. Increase in red blood cell count
• B. Increase in white blood cells
• C. Decrease in red blood cell count
• D. No change

Answer: (A)

Exposure to high altitude causes hypoxia, which stimulates the kidneys to release erythropoietin. This hormone increases red blood cell production in the bone marrow, boosting the blood’s ability to carry oxygen. That enhanced oxygen transport is the key hematological adaptation helping performance at altitude. White blood cell numbers don’t rise as a specific altitude adaptation, and a decrease or no change in red blood cells wouldn’t fit the typical acclimatization response.
