Trimetazidine, also called TMZ, is a drug used to deal with the center situation angina, so it might sound unusual that it is presently on the coronary heart of a doping scenario on the 2022 Olympics in Beijing. Determine skater Kamila Valieva of the Russian Olympic Committee, a gold-medal favourite within the girls’s particular person competitors, examined constructive for trimetazidine in December through the Russian nationwide championships. A panel convened by the Courtroom of Arbitration for Sport, nonetheless, decided that Valieva shall be allowed to proceed competing on the 2022 Olympics as a result of, amongst different issues, Valieva’s standing as a “protected particular person” below the age of 16 and the “critical points” across the timing of the constructive end result notification.

However what’s trimetazidine, and why is it thought-about a banned substance by the World Anti-Doping Affiliation (WADA)? TMZ is listed as a “metabolic modulator,” a kind of drug that, in response to a 2011 assessment, impacts the center by “increas[ing] glucose metabolism on the expense of free fatty acid metabolism, thereby enhancing environment friendly use of oxygen.” (One other instance of a metabolic modulator is meldonium, which Maria Sharapova examined constructive for in 2018.)

Particularly, trimetazidine makes your coronary heart higher at pumping blood to the remainder of your physique; it makes your coronary heart muscle “optimally purposeful.” Elevated blood move delivers extra oxygen to the physique’s muscular tissues, which helps them carry out higher – a transparent profit to athletes.

In different phrases, “TMZ can be utilized by athletes to enhance bodily effectivity, particularly within the case of endurance sports activities,” defined a 2014 research, which checked out Polish athletes who had been caught taking the drug. WADA has listed trimetazidine as a banned substance since 2014, and athletes are prohibited from utilizing it always. The drug is often prescribed for folks with angina, or chest ache that outcomes from lowered blood move to the center.

Previous to Valieva’s constructive check, the highest-profile confirmed use of trimetazidine by an athlete is tied to Solar Yang, a Chinese language swimmer and five-time Olympic gold medalist. In 2014, Solar served a three-month doping suspension for taking trimetazidine, which he mentioned he was utilizing for angina-related chest pains. Solar is presently serving an unrelated four-year ban for breaking antidoping guidelines.

Within the 2022 Winter Olympics in Beijing, in the meantime, just one competitor to this point has been formally suspended for a constructive doping check as Valieva’s case awaits its conclusion. Iranian skier Hossein Saveh Shemshaki examined constructive for an anabolic steroid on Feb. 7, earlier than competing, and is now “prevented from competing, coaching, teaching, or taking part in any exercise” through the Olympics, the Worldwide Testing Affiliation mentioned in an announcement.
