Is blood doping to increase an athlete's oxygen supply permitted in most endurance sports?

Blood doping refers to the practice of increasing the number of red blood cells in the bloodstream to enhance athletic performance, particularly in endurance sports by improving oxygen delivery to muscles. This practice is considered unethical and is prohibited by most sport governing bodies, including the World Anti-Doping Agency (WADA).

Athletes are subject to strict regulations regarding methods and substances that can enhance performance, and blood doping poses serious health risks such as increased blood viscosity, which can lead to heart complications or stroke. Therefore, the correct understanding is that blood doping is not permitted in most endurance sports, aligning with the principles of fair competition and athlete safety.
