When she submitted a pattern for testing in December, Valieva defined that she was taking hypoxene and L-carnatine together with one other compound, Supradyn, an immunity-boosting complement, in line with paperwork examined by the Simply. All three of those substances are allowed.
To clarify the presence of the banned drug, TMZ, Valieva’s legal professional, argued that she was “contaminated” with the drug, presumably via contact together with her grandfather, who appeared through video to say he was taking the drug.

Russian newspaper Pravda reported that Valieva’s attorneys argued through the listening to: “There could possibly be a wide range of methods it acquired into her physique. For instance, grandfather drank one thing from a glass, sage acquired in, this glass was by some means later utilized by an athlete. Or the drug settled on a floor, traces remained, the drug settled on that floor, which the athlete then drank.”
Can the drug be handed from one individual to a different so simply, and in that case, would it not present up within the recipient’s urine pattern, as Valieva’s legal professional claims? “It jogs my memory of youngsters I knew who mentioned they acquired STDs from the bathroom seat,” says Dr. Steven Nissen, heart specialist on the Cleveland Clinic.
Nissen says he is unfamiliar with how delicate the assays utilized by the WADA lab, a scientific measurement, are, however says that testing optimistic for a substance by ingesting from the identical glass as somebody taking it’s “very far.” fetched”.
“It’s troublesome to make definitive statements with out figuring out the assay [test] sensitivity, however it appears very, not possible,” he says.
Valieva’s legal professional additionally claimed she might have come into contact with the drug on a floor after which by some means ingested it. dr Donald Lloyd-Jones, president of the American Coronary heart Affiliation and chair of preventive drugs at Northwestern College’s Feinberg Faculty of Drugs, says, “I have never seen any proof that it is absorbed via the pores and skin.” He admits he would not is aware of how a lot of the drug was detected within the Athlete’s pattern, which would supply data on whether or not temporary publicity to a small quantity of the drug may clarify her optimistic check.
Lloyd-Jones additionally factors out that sufferers have to take TMZ 3 times a day as a result of it’s metabolized by the physique and eradicated comparatively rapidly. Taken on the permitted dose, the drug would attain its peak ranges within the blood inside two to 6 hours, and most can be eradicated inside 24 hours. “It appears unlikely that slightly bit on a glass or on her pores and skin would have resulted in a optimistic check except it occurred proper earlier than she gave the pattern,” he says. “One can draw conclusions that the publicity was both very latest, very near her check, or that she was extra chronically uncovered.”

Whereas TMZ is not accessible within the US, Nissen says there is a comparable drug, ranolazine, that is permitted by the Meals and Drug Administration. This drug additionally shifts the vitality supply coronary heart cells use from fatty acids to glucose, which is extra environment friendly. “That is why it really works for angina,” says Nissen. “It permits folks to do extra with much less blood circulation. For an athlete it could be conceivable that it could have an identical profit and make the center work extra effectively and provides it a small benefit.”
In line with Lloyd-Jones, this metabolic pathway additionally results in much less formation of lactic acid, which may trigger muscle fatigue. “There may be information from small research in coronary heart failure sufferers that counsel higher cardiac output in sufferers with a failing pump,” he says. “However whether or not that may present the identical profit in a younger, wholesome particular person — I do not suppose we all know.”
It is also unclear what the results of taking these compounds whereas the physique is youthful. “It is actually worrying, particularly in an adolescent whose physique remains to be growing,” says Lloyd-Jones. “We actually do not perceive the long-term results of fixing somebody’s physiology at that age.”
Whereas the Courtroom of Arbitration for Sport dominated that Valieva can compete in Beijing, her anti-doping case stays unresolved and awaits additional investigation. Meaning the gold she and her teammates gained within the crew competitors and any medal she wins within the ladies’s competitors may doubtlessly be revoked if anti-doping officers conclude she was doped and utilizing an unfair profit has occurred.
That is topic to further testing of a second pattern, drawn from the identical urine as your first pattern, analyzed to substantiate the optimistic outcomes of the primary pattern.
