Tour de France riders are inhaling carbon monoxide in 'super altitude' recipe
Top teams Visma and UAE confirm they have access to specialized equipment for testing, but deny using the potentially powerful new method for performance enhancement.
Escape Collective can reveal that multiple Tour de France teams are using the controversial and potentially dangerous practice of inhaling the deadly gas carbon monoxide to optimise their athletes’ altitude training. Lundby, the Detalo CEO and Israel-Premier Tech consultant, recently co-wrote a letter to the Journal of Applied Physiology, where he labelled CO inhalation for direct, altitude-like performance gains an “utterly toxic approach.” A study published in Medicine & Science in Sports & Exercise in 2020 by Walter Schmidt, another researcher with deep background in the field and co-founder of a company that, like Detalo makes CO rebreathing equipment, found a 4.8% increase in Hbmass and a 2.8% bump in VO2max, or maximal oxygen uptake, after three weeks of CO inhalation multiple times daily.
