How does blood doping Erythropoietin work?
The increase in red blood cells causes an increase in the number of hemoglobin molecules per unit blood. Hemoglobin is the primary molecule that carries oxygen in the blood. More oxygen in the blood allows more oxygen to be delivered to the exercising muscles. Studies have shown that blocking hemoglobin causes a reduction in exercise performance, or adding hemoglobin causes a clear increase in exercise performance.
