However what are the brokers of the Worldwide Testing Company (ITA) searching for? This UCI physique, which operates utterly independently, has been solely answerable for implementing the battle towards doping in biking since 2018. It’s he who organized the checks of Tadej Pogacar and Jonas Vingegaard during the night from Saturday to Sundaythen ordered an enormous wave of management throughout the remaining day, thus triggering incomprehension and anger of the runners’ union.
The query of the results on the riders’ restoration arises, particularly after the Dane’s fall on Sunday which pressured him to desert. Past the discontent of the peloton, the motivations of the ITA are intriguing. As a result of to hold out these checks over an distinctive time slot, that’s to say between 11 p.m. and 6 a.m., the company needed to acquire the authorization of a judge of freedoms and detentionand to have “severe and constant suspicions” justified.
This notion is sort of imprecise, and doesn’t essentially imply that the company had in its possession exact info on the doping practices of Pogacar or Vingegaard, winners between them of the final six editions. However meaning, on the very least, that she is exploring an avenue. Thesis nourished by the testimony of Oliver Naesen, Decathlon-CMA CGM rider who is just not on the Tour, in a podcast from Dutch media HLN broadcast on Sunday:
« There are doping substances that solely keep within the blood for about three hours. I heard they had been searching for progress hormone. That is the primary time I’ve heard of this: progress hormone monitoring. »
Reached by phone this Tuesday, Physician Gérard Dine, professor of biotechnology and doping specialist, confirms. “There are basically three issues searching for in these samples: micro-doses of EPO, micro-doses of testosterone and micro-doses of progress hormone. » To know clearly, let’s put apart testosterone, which is a chemical molecule. Development hormone, like EPO, is a protein. Known as GH, for “Development Hormone”, it’s made within the pituitary gland, a small gland situated on the base of the mind.
IGF-1, the hormone on the coronary heart of suspicion
Drugs, and extra notably biotechnology, first cloned GH to deal with progress retardation issues. An advance which, as is usually the case, has been misused by some for dishonest functions. “For the reason that 2000s, GH has been utilized in doping, however it isn’t very efficient since runners have by definition completed rising,” explains Gérard Dine. Everybody then turned to its cousin, liver progress hormone, referred to as IGF-1 (for “Insulin Development Issue”). That is what’s going to curiosity us within the case of the bicycle.
Insulin, produced by the pancreas, is a hormone that manages all the sugar system, due to this fact the manufacturing of power in our physique. The hormone produced by the liver, our well-known IGF-1, works in the identical approach. It boosts cell multiplication, notably in muscular tissues. In a phrase, it permits the physique to get better.
“EPO accelerates the oxygenation of muscular tissues, IGF-1 helps of their “remanufacturing”. With it, you battle towards muscle breakdown induced by repetition of efforts, explains our professor. Actually, these are dopings not for preparation for competitors, which might artificially enhance the rider’s degree, however for sustaining potential over an extended time frame. » No want for a drawing to see the profit over a three-week race.
Marketed because the mid-2010s, straightforward to make use of, “Insulin progress Issue” is a part of the record of doping merchandise. However you’ll be able to simply discover them on the Web, assures Gérard Dine. Above all, he explains, it has a major benefit for many who wish to cheat: “it’s fleeting in our physique. Its half-life (i.e. the time required for half the amount of the drug to be eradicated; it may be as much as two or three days for EPO) is three to 6 hours, relying on the kind of product. If the dose used is a upkeep dose, and never a lift dose, it is rather tough to detect. »
The mandatory adaptation of all the management surroundings
That is the place we come to checks late at night time or in the midst of the night time. “To search out traces of it, we’d like focused controls, already, and that are carried out as shut as potential to the use,” he continues. For a restoration product, we are able to due to this fact think about use within the night or at night time, which led the ITA to proceed because it did for Pogacar and Vingegaard.
The anti-doping company’s analysis would due to this fact not goal a brand new miracle product that lately appeared within the peloton, however a widely known drug. Nonetheless, it all the time takes years for controllers to grasp how potential cheaters use the merchandise. “To establish a micro dose of EPO or IGF-1, you want a corporation of samples which was in no way what was in place. And as well as, the authorized surroundings should be tailored,” illustrates Gérard Dine.
All the news from the Tour de France
It’s not clear whether or not final weekend’s night time checks had been a primary, as French legislation has allowed it since 2015, and groups might have suffered them with out talking out. But it surely had been 5 – 6 years since analysts defined to the authorities that micro-doses within the bicycle needed to be taken care of. We’ll now have to mix this improvement within the battle towards doping with respect for the well being of riders. A fancy equation, as biking is sadly usually confronted with.
