Key details from second wave of retesting:
386 samples selected from 2008;
30 athletes tested positive;
From four sports and eight countries;
138 samples selected from 2012;
15 athletes tested positive;
From two sports and nine counties.
First wave of retesting:
454 samples selected from 2008;
30 athletes tested positive;
From six sports and 12 countries;
265 samples selected from 2012;
23 athletes tested positive;
So, they had collected more sample (454) from the Beijing (2008) Olympics than the London Olympics (265) for re-test. Why?
Does this show you the commitment of the Olympics in fighting doping as the authority repeatedly claimed (also in the press release) ?
Interestingly, these numbers also confirms a trend that we suspected/already know, regardless the low capability of the testings in catching the cheats: doping is/has been on the rise.
1st re-test positives
2008: 6.6% (from 30/454)
2012: 8.7% (from 23/265)
2nd re-test positives
2008: 7.8% (from 30/386)
2012: 10.9% (from 15/138, don't know why the # of re-test samples has largely reduced from that in the 1st re-test)
Total (1st+2nd) re-test positive:
2008: 13.2% (from 60/454, would be 14.4% if we use 6.6+7.8%)
2012: 14.3% (from 38/265, would be 19.6% if we use 8.7+10.9%)
One would expect the 2nd re-testing to yield a lower percentage of positives as the samples already excluded the 1st re-testing positive ones. The higher % yielded in the 2nd re-test just shows the potential prevalence of doping in the sports (again, confirms what we already know/suspected) and the testing technology is far behind the doping practices.
