Which one is considered doping? What are they? Blood manipulation • Blood manipulation is the practice of boosting the number of red blood cells in the bloodstream in order to enhance athletic performance. Because such blood cells carry oxygen from the lungs to the muscles, a higher concentration in the blood can improve an athlete's aerobic capacity and endurance. Blood doping can be achieved by making the body produce more red blood cells itself using drugs, giving blood transfusions either from another person or back to the same individual, or by using blood substitutes. • Blood manipulation is considered doping because there’s a chemical alteration of blood cells and it increases the amount of oxygen very quickly and not gradually. Altitude training • Altitude training is the practice done by some athletes of training for several weeks at high altitude, preferably over 2,400 meters (8,000 ft) above sea level. The body may acclimate to the relative lack of oxygen in one or more ways such as increasing the mass of red blood cells and hemoglobin or altering muscle metabolism. • Altitude training is not considered doping, because it’s not a chemical alteration of the blood cells. It’s a way of training which makes the oxygen in blood cells increase gradually, so that the athlete’s body can get used to the change.
