Blood Blood dopingdoping
To increase the blood’s oxygen-carrying capacity
•Blood is taken from the athlete several wks before a major competition
•The red blood cells are removed and the remaining components of blood are immediately re-injected to allow the body to rebuild it’s missing red cells
•A few days prior to competition the original red cells are re-injected
•This can increase the body’s red blood cell count by up to 20 per cent above normal
