Ben, it has nothing to do with foreigners, the issue is when someone produces a performance that is not really possible, that means that they have a medical team that is completely up on all testing methods used by the current world doping agencies, and have found a way to do it. At this point globally, that's all it means.
Other people who found such a way were Lance Armstrong, an American, almost caught many times, but just skirted full technical detection. And now finally, because it really was vile how he lied for so many years, he's largely been busted, but playing his constant game of constant denial to the end. For those who don't follow such things, every single one of his primary helpers who was hired to head other teams was subsequently popped for doping, which means, the us postal team had better doping doctors, not that they were magically better. A simple formula in such cases you can use is this: if all top level athletes in a sport are doping, which was the case during armstrong's reign as top doper globally, then you cannot beat them unless you are also doping, that's the vicious circle of doping. Bradly Wiggins, by the way, made a nicely snide offhand remark post tour win, he apologized for the relative dullness of his victory by noting that when heavy duty doping is removed, magical day long breaks somehow are no longer possible, nor are miraculous overnight recoveries that allow the next day's briliant break away victory. You remember, like the magical recovery Floyd Landis had to gain the yellow jersey after bonking the day before, via our good friend synthetic testosterone. Trained by the same group, worked with Armstrong, just didn't have the level of medical staff, so they messed up and it was detected. Like Armstrong, denied it to the very end, and still does. Embarrassing, I really wish these guys would be men and own their cheating, but they remain human scum and will deny it til they die, or have a change of heart, like Jose Canseco, another American well known in the doping world.
I remember one olympics where Ben Johnson appeared, and radically outsprinted the competition, it was totally obvious just looking at his physique that he was doping, steroids I believe in his case, and he was, then stripped of his medals. Was he Canadian or US, can't remember off the top of my head.
The US olympic training center was also involved in developing blood packing, which US cyclists used to win some events, until they developed ways to track hemocrit levels better, now that's not as easy to do, or they have to use more refined methods, ie, control and test for blood hemoglobin. Lance Armstrong, in either his last, or second to the last, tour de france, registered blood hemoglobin levels that never dropped during the race, but did not exceed the limit. This is not possible technically, but it was within the rules, which is one reason they now use blood passports as part of the detection methods.
So there you have some prime US doping, happy?
You're confusing high level and highly funded doping doctors and systems for individual brilliance. There's no way a girl can beat a guy's time who is top level in a strength event, that's totally absurd. Unless of course she's been changed into a guy partially via doping over time. It's all about masking, when to pull the active stuff out of the body so it isn't detected, and using better testing than the world antidoping groups use to make sure your athlete passes the drug test.
If you're not aware of the horrifyingly debilitating results of years of steroid use, look up some videos of old pro US wrestlers, who beg the young guys to not use steroids because it cripples you totally when you get older. Very sad. Since Chinese and Eastern European bodies aren't magically immune to such negative results, and since they aren't exactly known for having open media, China doesn't even have an open internet, not reading about their horrible later years is hardly meaningful, you expect the Chinese Communist party to publish such stories in the State media outlets?
There's some other points, but it takes too long to go through all this, but the comments re pro level training vs amateur have now nothing to do with reality,. US basketball, all pros. Most of the cycling teams, all pros. I dont' love that newish rule, but given that some countries spend fortunes to gain medals and national prestige, it's only fair in the end.
I was listening to NPR the other day, they were interviewing an antidoping person, who noted that currently, dopers vs antidoping bodies are sort of like bicycle track pursuit riders, only the dopers tend to be slightly ahead of the antidoping groups. They know the rules, they know the levels, they know the chemicals on the lists, all those have to be published, so the game is to keep your results of blood / urine tests within allowed limits, using whatever means necessary. This is why dopers tend to be ahead, sometimes far ahead, sometimes not so far. Testing does help by the way, it doesn't eliminate the problem, but it does make it less extreme and less obvious. That's what Wiggins meant when he referred to the dullness of the race, they can't pop in an extra pint of blood now and expect to get away with it, can't do epo straight out of the bottle, they have to use less blood for example when blood packing, and can't be using certain things during the live race, and so on. Sad, one reason I do not watch the olympics, by the way, and why I dont' really follow pro cycling anymore, I'm not interested in the wonderful world of chemistry battling it out.
