Doping allegations surrounding Chinas swimming team overshadowed events in the pool at the Paris Olympics, bringing the sports integrity into disrepute.
China has claimed recent reports of doping among 23 swimmers who tested positive before the Tokyo Olympics in 2021 were the result of food contamination an explanation accepted by the World Anti Doping Agency (Wada).
Chinese swimmers shrugged off the doping controversy, stressing that they have been subjected to a rigorous testing regime in the build up to and during the Games.
Telegraph Sport lays out what happened and explains why there is so much suspicion hanging over the Chinese team.
In April 2024, the New York Times published an investigation which revealed 23 Chinese swimmers tested positive for the banned substance trimetazidine (TMZ) months before the Covid-delayed Games began in July 2021. All of the swimmers were cleared by the China Anti-Doping Agency (Chinada) which blamed contaminated food. Chinas 30-member swimming team won six medals at the Tokyo Games, including three golds. Chinada said in a statement to the New York Times that its athletes had not violated any anti-doping laws and it was not obliged to publish any details without the consent of the athlete.
The revelation of past positive drugs tests among Chinas team have cast a huge shadow over the Paris Olympics, sparking fears that China is involved in a doping cover-up. It comes after Pan Zhanle, who was not one of the 23 swimmers implicated in the Times story, shaved almost half a second off his 100m freestyle time before setting another record for the fastest anchor leg in the mens 4x100m medley on Sunday night.
The issue has triggered a diplomatic spat between the US and China, while several Chinese swimmers claim they have been met with a frosty reception by their American and Australian competitors.
TMZ is found in heart medication and helps to metabolise fatty acids, which in turn helps the body to use oxygen. The drug allows for more blood flow to your heart and limits quick changes in blood pressure. Although it was developed for medical use in the 1970s, it only became a banned drug on Wadas list of prohibited substances in 2014.
In light of the Times report, World Anti-Doping Agency (Wada) confirmed that 23 Chinese swimmers tested positive for TMZ before the 2020 Tokyo Olympics, but accepted the countrys findings that this was because of substance contamination.
In a lengthy statement, Wada slammed the misleading and potentially defamatory media coverage of the issue. It also detailed that it had conducted an extensive review based on additional, unpublished scientific information on TMZ in which it consulted with independent scientific experts to test Chinas contamination theory that low doses of TMZ could have benefited the athletes during a swimming competition event.
Yes. One of the most high-profile cases involving TMZ is that of Chinas Olympic gold medallist Sun Yang, who was suspended for three months in 2014 after testing positive for the drug. Sun said he was prescribed the drug by an Olympic team doctor to treat chest pain who was apparently unaware it had been newly added to Wadas banned substances list. Sun was later banned for four years in 2018 after an altercation with drug testers in China involved him destroying blood vials.
China finished fifth in the swimming medals table at the Paris Olympics, with two golds, three silvers and seven bronze medals. Six of those 12 medals were won by Zhang Yufei, who was among the 23 Chinese swimmers who tested positive for TMZ before the Tokyo Olympics.
In response to a frosty reception during her medal ceremony over the weekend, Yufei responded: Why are Chinese athletes questioned when they swim fast, but no one dares to question [Michael] Phelps or [Katie] Ledecky previously?. I dont think the doping incident will have any serious impact on us because we are innocent.
Adam Peaty: Theres no point winning if youre not winning fair.
Three-time British Olympic champion
One of my favourite quotes Ive seen lately is theres no point winning if youre not winning fair. I think you know thats true in your heart. Even if you touch [the wall] and you know youre cheating, youre not winning fair, said Peaty.
So for me, if youve been contaminated twice, I think as an honourable person, I think you should be out of the sport. But we know sport isnt that simple. Ive also been asked by people who havent been under contamination, and I respect that, I dont want to paint a whole nation or a whole group of people with one brush. I think thats very unfair.
But there have been two cases of it and I think its very disappointing. Ive tried to keep it out of the conversations until now for the benefit of the team but I think were going to use that to our advantage over the next four years, whether Im there or not. I know these boys will carry that and well see how they do in four years time. But I think the people that need to do the job, wake up and do your job.
Brett Hawke: Its not humanly possible
Australian swimming coach who competed in 2000 and 2004 Olympic Games, speaking after Pans individual gold
Look, Im angry for a number of reasons. Look, my friends are the fastest swimmers in history, from Rowdy Gaines to Alex Popov to Gary Hall Jr, Anthony Ervin and all the way up to King Kyle Chalmers. I know these people intimately, Ive studied them for 30 years.
Ive studied this sport. Ive studied speed. I understand it. Im an expert in it, thats what I do, OK. Im upset right now because you dont win 100m freestyle by a body length on that field. You just dont do it.
It is not humanly possible to beat that field by a body length. I dont care what you say. This is not a race thing, this is not against any one particular person or nation, this is just what I see and what I know.
Thats not real, you dont beat that field. Kyle Chalmers, David Popovici, Jack Alexy, you dont beat those guys by one full body length in 100m freestyle. Thats not humanly possible, OK, so dont sell it to me, dont shove it down my throat. Its not real.
Chinada (China Anti-Doping): The New York Times wants to weaken our competitive ability
A statement issued on Wednesday
[The New York Times] main purpose is to disrupt the order of the Paris Olympic swimming competition, affect the psychology of Chinese athletes and weaken their competitive ability. This is extremely unfair and immoral.
Pan Zhanli: There has been no impact on me
100m gold medalist speaking via a translator after his world record individual win
I tried my best to get the best result. I was very surprised in the end that I broke the world record and it was a magical moment.
Last year I received 29 tests and never had a positive [result]. From May to July, I had 21 tests, no positive. Today we received a second test already.
I dont think there has been any impact [on me] because all the testing has been done in the normal procedure … So its not a big issue.
Simona Quadarella: We need answers
Italian distance swimmer after it emerged last week that two Chinese swimmers tested positive for a banned steroid in 2022
I think we need some answers from this situation, she said. We really dont have confidence, in the situation, in the testing system – in the testing system in other parts of the world.
Caleb Dressel: Do I have confidence in the case – No, not really
USAs seven-time gold medalist speaking before the Games started
When asked if he had confidence in the doping case against China, Dressel replied: No, not really. I dont think they have given us enough evidence to support how this case was handled.
