KROK 1 2020 – Question 109 · KROK (Medicine) · Physiology
When preparing for an important sports contest, it is recommended to train at high altitude (2-3 km above mean sea level). Prolonged exposure to such conditions leads to:
- A. Decrease of blood viscosity
- B. Improvement of plasma colloid-suspension characteristics
- C. Decrease of ESR
- D. Decrease of pO2, which stimulates erythropoiesis and increases blood oxygen capacity
- E. Increase of arteriovenous oxygen difference
Hint
Consider the chain of events that begins with thinner air at altitude and ends with an adaptation that benefits an athlete returning to sea level.
