UCI Bans CO Inhalation in Cycling from February 10

The International Cycling Union (UCI) has banned the use of carbon monoxide rebreathing devices outside of medical facilities to protect athletes' health. This decision, effective February 10, was made following reports during the Tour de France that some teams were using the gas to optimize performance by increasing haemoglobin levels. Carbon monoxide, while used in sports medicine to measure blood metrics, has been linked to health risks such as headaches and heart rhythm problems when inhaled repeatedly. The ban allows for its controlled use under medical supervision, aligning with UCI's commitment to athlete safety. The World Anti-Doping Agency (WADA) has not yet banned the practice but is investigating its effects. The UCI's move reflects a proactive stance on athlete health and safety amid potential misuse of the technique for performance enhancement.
