number of red blood cells.
1. A few weeks before competition you would have some blood removed into a into a bag like when people give blood. You freeze the blood. Your body will pretty quickly replace the blood to normal
levels. Before the race, you thaw and re infuse the blood. Now you (the athlete) have more than normal amounts of red blood cells. You can now carry more oxygen to yoru working muscles and have
an unfair advantage.
2. You can also inject a hormone called erythropoetin (EPO) to stimulate the bone marrow to make more red blood cells.
