Muscle cells are factories that take the raw materials, oxygen and glucose, and turn them into energy. Training increases the ability of the body to deliver oxygen to the cells and increases muscle size. More efficiency and more power yield better athletic performance. Increasing the number of red blood cells in the body increases the ability to deliver oxygen to tissues and that’s where blood doping and EPO come in.
