This question appears to be incomplete. During blood doping, the athlete will have blood drawn and stored. The athlete will then allow sufficient time for the body to replenish the removed blood. Immediately prior to the event, the athlete will inject the stored blood back into his/her system. Blood doping<span> effectively increases the number of </span>red blood cells<span> in the bloodstream to above normal. This enhances performance because blood cells carry </span>oxygen<span> from the </span>lungs<span> to the </span>muscles<span>, and a higher concentration of oxygen in the blood can improve an athlete’s </span>aerobic capacity<span> a</span><span>nd </span>endurance.
