Yes, I remember the 'stupidity' of Vainio well.
But the unfortunate events and story of how he was caught, only reinforces the evidence we have that points to long distance athletes from 2 specific countries, Italy & Finland, as being known dopers. Even then, it doesn't mean all distance athletes from those countries doped, but it is natural to suspect this group as being more likely to have; just as there is a heightened suspicion of Kenyan middle and distance athletes at present, down to dozens of positive test results in the last 3 years.
Also, while the current thinking is that 800m running is more aerobic (66%, you claim), this has changed quite considerably since the 80's understanding of the systems' breakdown. I have read accounts suggesting the ratio is 50%/50%, and in one training manual I have from 1985, written by Ron Hill and Harry Wilson (Steve Ovett's coach), they suggest the balance is 67% anaerobic to 33% aerobic! So this would seem to suggest that the philosophy of the time was that 800m running was more anaerobic, regardless if this is what now is the case?[/quote]C'mon man...didn't you read the info on Vainio's doping case from his own Wikipedia page under "Doping case at the Olympics 1984?" Here's an important part of it:
"In 1984, Vainio started his season by finishing third at the Rotterdam Marathon with a personal record of 2:13:04. After the race he gave a doping sample in the test organized by the Finnish Athletics Association. The test did not have official status and was merely considered to be a control test to help avoid Finnish athletes getting caught at the tests performed in international championships.
The FAA doing their own "control tests to help avoid Finnish athletes getting caught at the tests performed in international championships." Sounds more like a State-sponsored program to make sure all of their athletes aren't glowing from steroids at international competitions. Lol.
On the energy system of the 800m: As I linked; Duffield et al has ~66% aerobic (2001 study). Another study done by Spencer et al in 2005 has ~60% aerobic - no way near the 67% anaerobic/33% aerobic suggested by Ovett's coaches.
https://www.ncbi.nlm.nih.gov/pubmed/15966348"For the 800-m event, an increased aerobic involvement was noted with a 60/40% (male) and 70/30% (female) respective contribution."
