What is blood doping? GCSE PE paper 2

The video tutorial discusses blood doping, a method used to enhance athletic performance by increasing the number of red blood cells in the body.

The practice is particularly beneficial for endurance athletes like swimmers, cyclists, and runners, as it allows them to perform at higher intensities for longer periods without fatigue.
