越来越多人站出来了！外国网红：“紫薯脸”背后就是违禁药物_新浪财经

巴黎奥运会开赛以来，关于兴奋剂的讨论一直热火朝天。

一方面，美国对中国运动员药检多次发难，“格外关注”；另一方面，美国游泳队选手怪异的脸色引起了广泛争议，有网友将其戏称为“紫薯脸”。然而面对外界的质疑，美国媒体并没有正面回应，反而选择“掩耳盗铃”，特意调色，把运动员的紫脸P白了。

Some American swimmers had a purple discoloration on their faces after completing their races in the Paris Olympics swimming events, which has sparked widespread online discussion and suspicion.

“紫薯脸”到底是怎么回事，能不能通过正常原因进行解释？日前，加拿大知名健身网红格雷格·多赛特（Greg Doucette）在外网发布视频《揭露紫脸奥运游泳选手》（Exposing Purple Face Olympic Swimmers），截至目前获得24万点击。他认为美国游泳运动员之所以在比赛后变成“紫薯脸”，不可能是缺氧、皮肤病等天然原因，而是使用了兴奋剂。

格雷格分析道：

That is a definite sign they could be using ITPP, or they're doing blood doping.
很明显他们在使用ITPP，或者血液兴奋剂法。

The hemoglobin it has a certain amount of oxygen. When you use ITPP, it's willing to give off more oxygen. And the more oxygen it gives off, the faster you go. But also the more deoxygenated the blood becomes, and so you get that bluish purple face.
血红蛋白含有一定量的氧气。当你使用ITPP时，它会释放更多的氧气，释放的氧气越多，你游得就越快。但同时血液中的脱氧血红蛋白也会增加，你的脸就会变成蓝紫色。

ITPP，即三焦磷酸肌醇，一种违禁药物。这个药物目前已经被世界反兴奋剂机构（WADA）禁止，然而目前并没有好的手段对这种药物进行检测，这使得部分作弊的选手可以逃脱惩罚。

ITTP is a performance-enhancing substance that is prohibited for athletes. Sadly, as of now, its presence cannot be detected in human urine. This clearly makes it a preferred choice over the drugs that can be detected or have well-recognizable symptoms.

格雷格指出，美国和加拿大的反兴奋剂机构秘密允许选手使用这类无法被检测到的药物，并且有时候不会通报哪些运动员未通过兴奋剂测试。

Doucette also called out the US and Canadian anti-doping agencies for secretly allowing their Olympic teams to use undetectable substances in their blood. "Sometimes the countries do not even report the athletes that failed the dope test. That has happened in Canada, it's happened in United States," he said.

此外，澳大利亚媒体《珍珠与刺激》近日发布题为《真正的奥运作弊者请站出来》的报道，发声力挺中国选手并对美国提出种种质问。

文章一开头便犀利指出，因为美国如今在奥运会上不再是领头羊，所以希望将其热战和贸易战扩展到体育领域，或者至少是体育领域的反兴奋剂领域。美国希望对那些他们认为在比赛中作弊的人发出逮捕令并展开调查，然而这调查却只针对中国运动员。

Because they are no longer the top dog in the Olympics, the US now wants to expand its kinetic and trade wars into the sporting arena, or at least the anti-drugs section of the sporting arena.
The US has now opened a criminal investigation and wants to issue arrest warrants for people they deem guilty of cheating in sports, but here's the rub, they aren't interested in pursuing US Athletes, only the Chinese.

What many didn't know until a supposed Russian hack in 2016 is that Therapeutic Use Exemptions (TUEs) legalise taking banned substances in sport and the US have taken advantage of it. The US team is awash with athletes who need their TUEs. If the recent hacked and leaked information about the US use of TUEs is to be relied upon, they are already the world's greatest sporting cheats.
2016年一次所谓的俄罗斯黑客入侵事件后，许多人才知道治疗用药豁免（TUEs）能让体育运动中服用违禁药物合法化，而美国已经利用了这一点。美国队中充斥着需要用药豁免的运动员。如果网络黑客所透露的关于美国使用用药豁免的信息可靠的话，那么美国就是世界上最大的体育骗子。

文末写道，这种不当的竞争行为其实不仅仅是在体育领域，因为中国在各方面的崛起都引发了美国的危机感。而当美国发现无法通过技能、经验或实力维持霸权地位时，便决定在全球各个领域作弊，如贸易、军事和经济领域。当这种策略也失败时，削弱对手就成了备用策略。

The US has found it can’t maintain hegemony through skills, experience or prowess and has decided that cheating in the global arena, in trade, military and economics, is the best way forward and then, when that fails too, hobbling the opposition is the fallback strategy.
