Science 1Q. Isn it Hematocrit rise that determines performance?
(Science) A: If it was simply Hematocrit that improved performance, then athletes could remove a pint of blood, centrifuge it, tap off the plasma, and re-infuse just the red blood cells to increase their hematocrit levels. This doesn’t work as the total Red Blood Cell volume is what is important and actually affects performance. The body must create NEW Red Blood Cells to enhance performance.
