It's like saying "cyclist get better by drawing blood" when they just have their bloodwork done to see how they are doing with training.
They aren't sleeping attached to a car exhaust.
> A second, more aggressive approach, which is called carbon monoxide inhalation and uses the same equipment and techniques, steps into the scientifically new and much riskier realm of inhaling the poisonous gas for the express purpose of performance enhancement. A growing body of recent scientific research suggests CO inhalation can have a powerful impact on measures of aerobic capacity like VO2max, or maximal oxygen uptake.
> And there is no hard evidence that any WorldTeams are currently using CO inhalation for performance gains. But multiple sources for this article voiced concern that it might be imminent, and possibly already happening in cycling or other sports.
To go from that to "people dope now with CarbonMonoxide" is dishonest.
i think it's equally as dishonest to believe anything these teams say about topics which relate to doping, performance enhancements etc.
of course not a single team says that they're using these methods to get performance gains, why on earth would they admit it?
