Disappointing deduction Deano. You probably arrived at this discussion some 28 pages too late. Your response does not match with what I have been advancing over numerous pages. Rekrunner is saying that EPO doesn't work on the white man or any other non-East African for that matter, which is complete and utter nonsense. Rekrunner has pushed the argument that because westerners didn't perform better in the 1990s (or since) then pre-1985 (Coe, Ovett and Cram for the 1500m/mile for example) it must be proof of epo's impotence. But as you just stated young athletic males played soccer and other sports instead. Added to this is the declining birth rates, as you know the most common baby name in Britain and many other European countries is Mohammed. Most western countries have relied on immigration for population growth (hence Brexit, Trump and now Le Pen).
Baala is a North African that ran for France (though Willis did beat him in the 2008 Olympic final). He does look more like a European though, until you hear his name. But you are really confirming rekrunner's error, for if Baala & Cacho were less talented than Coe, Ovett, Cram or Ryun then how did they run faster times? It is called epo and it obviously works.
I mentioned Walker because his urine sample tested in 1984 was deemed by the UCLA labs as being the cleanest sample given by an elite athlete at the games (though he bombed out at the 5000m). At that time he was 32 but still could run sub-3:50. His sample was used for comparative analysis and for model building until the 1990s software revolution. As I mentioned I do believe that white runners could run faster than Walker naturally in the pre-1985 I just used him as a starting point to establish a trend in the case rampant steroid abuse or blood doping succeeded him. I never stated he was faster than Ryun, but truth is he had a longer more successful career. But you are beginning to sound like Calculo. Ryun's cinders tracks were rolled pre-race which makes the conversion difficult. So 3:30 no. Ryun's 1966 880yds was considered the first WR on a synthetic track. I can vouch having raced 3k & 5k in recent weeks on asphalt, a bumpy grass track and a mondo track I can a test that there is no statistically significant difference between mondo and a 5k on asphalt but the bumpy grass track is 4/5s per km slower than both. Ryun did run on synthetic tracks later in his career and failed to run as fast. But let us assume 3:31-flat for Ryun in 1967, who did 110 miles per week, did 40 x 400m sessions, so he was well conditioned by modern standards and he was light years ahead in his use of altitude training. Now if we fast forward in time 25 years to the early-1990s the WR for 1500m by your own analysis (at 3:29.5) had only improved by 1.5s (or 0.5s if your unrealistic 3:30 time is used) and that record was held by Aouita who was as dirty as they come. Yet in less than 6 years it melted by 3.5s!!!! Now what could explain this sudden drop? But what is worse, since 1998, in nearly twenty years the best miler Asbel Kiprop (who's coach di Rosa looks pretty dodgy), who has not failed a doping test in the ABP era, can barely get within 0.7 of the 1500m WR and Kiprop weighs next to nothing and has strides that are huge and effortless (heck he can almost beat Rudisha in 800m races so he is fast). This is not a progression it is a decline. Now a straight line from Coe, Ovett & Cram to Kiprop is entirely plausible but not the 1990s-2005 detour.
Now Deano if you really want me to put the knife in (or a rusty spoon) I can because the truth is, unlike the tracks for Ryun in the late-1960s, the track Herb Elliot ran on in the 1960 Olympic final was totally shot and is clearly worth 1s per lap which would mean that he would have beaten Seb Coe in 1984. Again minimal improvement in the pre-EPO period.
Now, Ryun I hope was clean, but steroids were actually more rampant in the late 1960s than what people assume (shot putters were on it at the 1956 Olympics).
As I stated previously I would be gutted if Ovett was doping but I have to say 1984 does sound like an early-epo era cycling story, he was only 28 and was having a heart attack. Still I hope not. I sort of know an elite French triathlete who died recently, that sounds fishy. The truth is rekrunner has no proof that athletes were not on steriods, stimulants or doing blood doping pre-1985. Again, I hope that they were clean but if they weren't it gives a distorted/understated picture for epo's affects on the men's 1500m (or longer distances).
Western 1500m/mile times actually fit the same performance chart we see in men's (discus, shot put, hammer, high jump, long jump) and women's (shot put, discus, long jump, heptathlon, high jump) field events peaking in the 1985-1989 period then a drop off since. This is also visible in women's short distances (100m-800m) and was clearly influenced by out of competition testing being introduced in 1989.
Track and field was big in Europe in the 1990s and after, while football was big before 1985. Pele, Maradona, George Best etc pretty famous footballers.
The 1500m seems to have come into focus here, but really the 5 & 10 makes far more sense when discussing epo. Uncoordinated and visibly less talented white runners (Baumann and Kennedy) ran significantly faster than pre-1985 whites. People that were alot faster over short distances than the two I mentioned.
Renato argues that EPO works for sea-level natives but doubts it works for Kenyans and Ethiopians. Rekrunner actually argues the opposite that it doesn't work for sea level athletes at all.
Now a sensible argument from rekrunner would have been that standard epo may not work for all people but this can be countered with fact that numerous different epo's have been produced to cater for differing genotypes.
