Ouch. For "systematic doping"... http://espn.go.com/olympics/story/_/id/16282389/iaaf-upholds-ban-russian-track-field-athletes-olympics-rio-de-janeiro
Why would the IAAF only pick on Russia Other countries athletes surely cheat as well, but thinking, those athletes do it on their own. No help from top to bottom as it seems Russia has. I remember in the 70's China and Russia were using athletes as test tubes. One only had to look at facial features of women swimmers etc to see there was something going on.
I think its been proven that numerous Russian Athletes were doping, and that their coach was in on it, and it came from 'higher ups'...so Russia isn't being targeted for Political reasons. Numerous Russian Athletes have tested positive for doping, with a Chain of Command...so a very justified banning.
It's also been proven that "other countries", have had coaches involved, and whole medical teams involved. Indeed, "other countries", prior to hosting Olympics, have set up the then most modern labs for testing and, for the expressed purpose of "training personnel", allowed athletes to test themselves without fear of repercussions. That Olympic year and several thereafter that nation had some amazing results in athletics, especially for woman. Several records which still stand today, even. Ah, the joys of a healthy mind in a healthy body. Shame about the moral corruption...
