The use of carbon monoxide to enhance performance caused controversy during the 2024 Tour de France, with some riders, including winner Tadej Pogačar, using to inhale the gas. what do you think?

website collective escape It was revealed on July 13 that Slovenian Tadej Pogačar, who won the third Tour de France in July 2024, used a carbon monoxide recuperator during his preparations for the Grande Boucle. After initially denying the message, the cyclist acknowledged it while noting that it was not a direct inhalation of carbon monoxide, but rather a test to see how his body would react in conditions similar to high altitude.

In addition to Emirates Team Emirates, Visma Lease a Bike and Israel-Premier Tech have also endorsed the practice. WADA doesn’t officially ban this, but is it ethical?

CO makes pedaling faster

This new “secret” weapon used by the most advanced cycling teams – and with significant financial resources – involves the use of carbon monoxide recuperators (CO rebreathers). The cycling teams’ communications services claim the devices are specifically designed to measure carbon dioxide in the blood. This machine allows you to measure the blood volume and the total mass of hemoglobin, an essential protein in endurance sports as it ensures the delivery of oxygen in the body. According to cycling-dopage.com, breathing in small amounts of carbon monoxide is not dangerous. This method has been used for many years to measure total hemoglobin mass. But some teams aren’t content with that, using carbon dioxide inhalation to recreate the effects of altitude. Plays a decisive role in the assembly stage.

What is the principle?

The cycling-dopage.com website believes teams can use carbon monoxide as part of a wider protocol. Marc Kluszczynski, pharmacist and head of Sport & Vie magazine’s “Doping Frontiers” section, explained that teams can eliminate carbon monoxide residues before games by performing “inhalation treatments” before games. They eliminate carbon dioxide-laden hemoglobin by breathing hyperbaric oxygen, which requires a pressurized chamber. Experts say eliminating carbon monoxide would bring marginal benefits. On the other hand, he sees the advantages of hyperbaric oxygen therapy at every stage. This practice will promote the dissolution of oxygen in the plasma and subsequent saturation of hemoglobin, allowing for better oxygen consumption during this phase. Hence better athletic performance.

Many believe that inhaling the gas to enhance athletic performance is a disguised doping and have called for stricter anti-doping regulations
