Suppose your biking partner claims that hyperventilating at the bottom of steep hill climbs is a good idea because it will "increase the O2 saturation of the blood" and thereby provide "more O2 for leg muscles during the climb." Hyperventilation reduces the CO2 content of blood. a. Given this fact, is hyperventilation likely to increase O2 delivery to muscles (as your biking partner claims) or not?

No, hyperventilating will not increase oxygen delivery to the muscle due to decreased concentration of Carbon dioxide in blood ...

Explanation:

The reduction of carbon dioxide in the blood will change destabilize tense state of the hemoglobin into relaxed state.

As a result, the p50 value of hemoglobin reduces and the release of oxygen from hemoglobin is hindered.

Thus the oxygen delivery to the muscles will not be increased.
