摘要：The continuing desire to improve performance, particularly at the national and international levels, has led to the use of ergogenic aids. Ergogenic aids are defined as “a procedure or agent that provides the athlete with a competitive edge beyond that obtained via normal training methods”. Random drug testing has been implemented in an effort to minimize an athlete’s ability to gain an unfair advantage. However, other means of improving performance have been tried. Blood doping has been used to enhance endurance performance by improving oxygen delivery to working muscles. As oxygen is carried in combination with the hemoglobin, it seems logical that increasing the number of red blood cells (RBC’s) in the body would increase the oxygen carrying capacity to the tissues and result in improved performance. The first experiments of removing and then reinfusing blood showed a significant improvement in performance time on the treadmill (Ekblom et al., 1972). This process is now known as blood doping.
