What is the main reason for athletes doing "high altitude" training?!


Question: What is the main reason for athletes doing "high altitude" training?
A. increase blood flow to the lungs to pick up more oxygen
B. adapt to cold climate
C. increase their ability to transport more oxygen
D. increase the rate of release of oxygen from oxyhemoglobin into the tissues

I think the answer is C but I'm not sure.

Answers:

A. Blood flow to the lungs does not increase. However, at a high altitude, your body produces more red blood cells, so a higher concentration of RBC's reaches the lungs, but there is no marked change in blood flow to the lungs; there is, however, an initial increase in ventilation rate, while the blood still has few RBC's, and a decrease back to normal ventilation when a new RBC blood level (hematocrit) has been established for better oxygen transport.
B. Adaptation to cold climate is independent of altitude.
C. Red blood cell's transport oxygen via oxyhemoglobin, which is formed when oxygen in the lungs is exchanged for carbon dioxide in the lung's alveoli. The lung's oxygen and the RBC's hemoglobin form oxyhemoglobin, a protein that transports oxygen to different tissues. The chemical bonds between oxygen and hemoglobin are very weak, which makes it easy for blood to readily deliver oxygen to every tissue.
D. The rate of release of oxygen from oxyhemoglobin does not change, it is determined by the strength of the chemical bonds within, and the chemical properties of these bonds do not change with altitude, so the rate of release remains the same.

Answer: C

To condition their body to work with less oxygen, creating better use of oxygen, which will enable them to expend more energy, over a longer period of time. in a more oxygen saturated atmosphere.



I think C too



C. is correct
