However as first reported by way of The Break out Collective, it’s imaginable to misuse this check apparatus to head from merely checking out your Hb mass to bettering it with extended inhalation. TrainingPeaks has an in-depth article at the science in the back of CO Hb checking out right here, however the in need of it is going like this:
“First, an athlete in most cases does a mix of breath and blood assessments to measure their baseline carbon monoxide (CO) ranges prior to the true check is carried out.
The check itself comes to the athlete breathing in a small quantity of carbon monoxide diluted with oxygen. This mix is inhaled and exhaled thru a closed circuit for 2 mins. The carbon monoxide the athlete inhales then binds to the hemoglobin in purple blood cells to shape carboxyhemoglobin.
After two mins, the volume of carboxyhemoglobin that is still within the breath and blood is re-measured and in comparison to the baseline ranges measured in the beginning of the check. The effects are then used to calculate the athlete’s overall hemoglobin mass.”
That checking out can then be used to evaluate an athlete’s altitude adaptation, nevertheless it is also abused if an athlete had been to “frequently inhale the tracer to simulate hypoxia and prompt an increase in hemoglobin and other performance metrics.”
That’s the place the UCI is trying to attract the road with their newest ban. Calling it “a ban on repeated inhalation of carbon monoxide,” the UCI will nonetheless allow one CO inhalation to measure overall Hb mass. Or two, it seems that, mentioning “The inhalation of CO will remain authorised within a medical facility and under the responsibility of a medical professional experienced in the manipulation of this gas for medical reasons and in line with the following restrictions: only one CO inhalation to measure total Hb mass will be permitted. A second CO inhalation will only be authorised two weeks after the initial Hb measurement.”
For extra main points, take a look at the entire press unlock beneath which additionally features a amendment for UCI WorldTeams to stay eligible.
From UCI:
The Control Committee of the Union Cycliste Internationale (UCI) met in Arras (France) on 31 January and 1st February, along the 2025 UCI Cyclo-cross Global Championships, which can be being held in Liévin from 31 January to two February.

As a reminder, CO is often utilized in sports activities medication to measure overall haemoglobin (Hb) mass and blood quantity, particularly to inspect the results of staying power coaching and altitude publicity on oxygen sporting capability. Then again, its repeated inhalation can lead to acute and persistent well being issues, for instance complications, lethargy, nausea, dizziness, and confusion. Such signs can aggravate at any time and turn into issues of middle rhythm, seizures, paralysis, and lack of awareness.

The inhalation of CO will stay permitted inside a scientific facility and beneath the duty of a scientific skilled skilled within the manipulation of this gasoline for scientific causes and in step with the next restrictions: just one CO inhalation to measure overall Hb mass will probably be authorized. A 2d CO inhalation will simplest be permitted two weeks after the preliminary Hb dimension.
For riders in UCI WorldTeams, UCI Girls’s WorldTeams and UCI ProTeams, any CO inhalation for the aim of figuring out overall Hb mass will have to be recorded within the scientific report established for each and every athlete, in compliance with Articles 13.3.020 to 13.3.026 of the UCI Clinical Laws.
The UCI’s ban is impartial of the Global Anti-Doping Code and the UCI Anti-doping Laws, on the other hand the UCI has formally asked the Global Anti-Doping Company (WADA) to take place at the repeated use of CO out and in of pageant.
With the purpose of making sure the participation of the arena’s very best groups in all of the maximum prestigious highway occasions, the UCI Control Committee licensed a amendment to the participation laws for the UCI WorldTour and UCI Girls’s WorldTourfrom 2026.

UCI President David Lappartient mentioned: “The UCI takes a daring and essential stance by way of banning the repeated use of carbon monoxide inhalation on scientific grounds.
