Document Summary
Reinfusion of packed rbcs or use of artificial epo. Why would blood doping be advantageous to athletes? (hint: think about the types of skeletal muscle fibers and their uses. ) Blood doping is accomplished by either the reinfusion of packed red blood cells or through the use of erythropoietin (epo) to stimulate erythropoiesis (formation of erythrocytes). Share your answers to the following questions by posting them on the discussion board: Hemoglobin accounts for more than 90% of the protein present in erythrocytes. The amount of hemoglobin in blood is measured in grams per deciliter of blood (g/dl; 1 deciliter (dl) = 100 milliliters (ml)) using a hemoglobinometer. Males again have more hemoglobin (14-18 g/dl) than females (12-16 g/dl). Infants also have relatively high hemoglobin contents. The minimum hemoglobin concentration needed to donate blood is 12. 5 g/dl. Mean corpuscular hemoglobin (mch) is the average mass of hemoglobin (hb) in one erythrocyte. It is measured as (10 x hemoglobin concentration.
