What is blood doping and why is it banned?

Blood doping is an illicit method of improving athletic performance by artificially boosting the blood’s ability to bring more oxygen to muscles. In many cases, blood doping increases the amount of hemoglobin in the bloodstream. Hemoglobin is an oxygen-carrying protein in the blood.

Why is blood doping banned in the Olympics?

How common is blood doping and what are the consequences of the practice?

Our results from robust hematological parameters indicate an estimation of an overall blood doping prevalence of 15–18% in average in endurance athletes. The confidence intervals for blood doping prevalence range from 9 to 28% with wide discrepancies between certain countries.

How does blood doping affect athletic performance?

In short, blood doping increases the number of red blood cells available to provide oxygen to the athlete’s muscles, allowing for improved performance. Studies have shown that this method can increase performance by up to 10%, especially in endurance sports.

How does blood doping affect cellular respiration?

Blood doping requires athletes to remove and store their own blood, then inject it back into themselves later. and water, and release energy for the body in the process. More oxygen in the body means a faster rate of cellular respiration and increased release of energy.
