So to be clear, with all these late 1990 and 2000 Moroccan examples, you are helping me argue that there is no "as soon as" link between "through the roof" improvements, which didn't occur until post-1990, and EPO-availability as early as 1987, and O2-vector doping as early as the 1970s.
Just to be complete, blood transfusions started earlier. The studies on the benefits of blood transfusion for endurance events go back to the 40s...
Here word for word from a 2004 review paper (doi: 10.1136/bjsm.2003.007195):
HISTORY
The first alleged use of blood boosting in sport was in the 1960s, when a French four times winner of the Tour de France (1961–1964) was named as one of the first cyclists to use the technique. Widespread use among endurance athletes (especially running, cycling, and cross country skiing) started after the 1968 Olympic Games...
Well, and how did the performances change?
Decade by decade for non-African born male 5000 m runners, averaged over top-5 times (feel free to check the stats):
1960s: 13:22.5 -> some steroids, very few blood "dopers"
1970s: 13:13.4 -> -9s; unlimited blood transfusions + primitive steroids
1980s: 13:04.9 -> -8s; height of cold war doping era, unlimited blood transfusions, steroids virtually undetectable
1990s: 12:59.2 -> -6s; unlimited EPO, begin serious steroid testing
2000s: 12:56.3 -> -3s; begin EPO testing, partial ABP
(2010s: 12:57.7 -> +2s; full ABP incl. steroid module - but still 2 years to go) – needs to be updated
Decade by decade for non-African born male 800 m runners, averaged over top-5 times (feel free to check the stats):
1960s: 1:44.6-> some steroids, very few blood "dopers"
1970s: 1:43.3 -> -1.3s; unlimited blood transfusions + primitive steroids
1980s: 1:42.2 -> -1.1s; height of cold war doping era, unlimited blood transfusions, steroids virtually undetectable
1990s: 1:42.8 -> +0.6s; unlimited EPO, begin serious steroid testing
2000s: 1:42.8 -> +/-0s; begin EPO testing, partial ABP
(2010s: 1:42.8 -> +/-0s; full ABP incl. steroid module - but still 2 years to go) – needs to be updated
Other observations with focus on male non-Africans as per rek's guidelines:
- times improved a lot from the 70's to the 80's (roid time)
- 5000 m times improved hugely after the 80's as well (no test for EPO)
- the fastest decade in the 5000 was the 00's (pre ABP)
- the fastest decade in the 800 was the 80's (roid time)
- the fastest 800 overall was in the 80's (roid time)
- the fastest 5000 overall was in the 90's (no test for EPO)
