blood doping

use of erythrocyte transfusions or erythropoiesis-enhancing drugs to improve athletic performance.

blood doping

n.
The process of increasing the number of circulating red blood cells in order to increase the oxygen-carrying capacity of the blood for improved athletic endurance, performed by blood transfusion or administering erythropoietin. Also called blood boosting.

blood doping

the administration of blood, red blood cells, or related blood products to an athlete to enhance performance, often preceded by the withdrawal of blood so that training continues in a blood-depleted state.
A maneuver in which an athlete places a unit of autologous blood in storage to be transfused immediately before an endurance event—e.g., a long-distance race—resulting in increased athletic performance due to better O2 delivery to the tissues

blood dop·ing

(blŭd dōp'ing)
Infusion of red blood cells, usually freeze-preserved autologous packed red blood cells, to increase hematocrit and hemoglobin levels; used by endurance athletes to increase blood's oxygen-carrying capacity and thus enhance endurance performance.
Synonym(s): blood boosting, induced erythrocythemia.

blood doping

a procedure banned by the World Anti-Doping Agency (WADA): the administration of a blood transfusion to a sportsman or sportswoman in order to increase the oxygen-carrying capacity of the blood and as a result to improve performance. Most commonly, this involves removing up to a litre of the person's blood and storing this while the body's normal mechanisms replace the loss. At a later date, usually just prior to competition, the removed blood is transfused back into the circulation. Though banned, it is still used in some sports such as athletics and cycling as detection is difficult. The procedure is considered to be against the ethics of sport. Risks include renal damage, transmission of infection and circulatory overload.

With the emergence of the hematological module of the Athlete Biological Passport and the indirect detection of blood doping (1-6), this framework has changed: Unlike a conventional doping test sample that either contains a forbidden substance or not, a raw profile of biological markers does not offer clear-cut information on the use of a prohibited substance or method a priori, because such evidence does not detect the substance itself, but only its effects.
