What is Xenon Doping and how does it trigger the EPO hormone in the body?
Xenon doping refers to the use of xenon gas (Xe) to artificially stimulate the body’s oxygen-response system, mainly with the aim of improving athletic performance. Xenon is a colourless, odourless noble gas. It has been prohibited by the World Anti-Doping Agency (WADA) as a hypoxia-inducible factor (HIF)-activating agent.
The important mechanism involves erythropoietin (EPO), a hormone produced mainly by the kidneys that signals the bone marrow to make more red blood cells. Xenon exposure can activate the HIF pathway, which is normally switched on when the body senses low oxygen. This can increase EPO levels and potentially stimulate red-blood-cell production, improving the blood’s oxygen-carrying capacity. A controlled human study found that xenon exposure increased EPO levels, although later research found that longer-term exposure did not necessarily improve athletic performance.
