1) I agree with you -- cycling and running are completely different sports. It hardly makes sense to draw conclusions about one from the experiences of the other.
2) It's clear EPO works to increase red blood cells. It's less clear how that maps to performance.
casual obsever wrote:1) Cycling - i.e., the TdF, is a different story, because there was much less focus on state-organized doping (contrast for example the lack of success of the Germans, Americans, Brits and the Russians in the TdF with that in the Olympics in the 70s and 80s), as that Cold War doping was focused on Olympic competitions.
2) Yes. Doping, including EPO, works for everyone. Don't pretend to be naive.
Each gram of hemoglobin in the RBCs binds 1.39 mL of oxygen. There is nearly 20 mL of oxygen in every 100ml of whole blood. The increase of oxygen transport capacity with extra hemoglobin from any method (autologous blood transfusion, all types of EPO, HIF stabilizers, xenon/krypton gas, living at high altitude…or even doing all of these methods at the same time like I do) will increase VO2max, lactate threshold, and aerobic endurance performance measured in time to exhaustion or time trial performance in everyone, including elite and non-elite cyclists, runners, swimmers, and XC skiers. Removing RBCs (with hemoglobin) out of the body will decrease VO2max, lactate threshold and endurance performance. If a lot more blood is removed, any human will eventually die. It does not matter if the human is male or female or British or Ethiopian or Kenyan or lives at high altitude or at sea level or below sea level.
Oxygen acts as the final electron acceptor at the end of the electron transport chain, located on the inner mitochondrial membrane, which produces ATP through the process of oxidative phosphorylation. The ATP provides the energy for all cellular activity in the body, which gives leg muscles the energy to be able to contract, which also gives humans the ability to run for long distances.
There is discussion of this and 83 other references for you to read in this article:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3874847/You will probably find something wrong with the studies in the article, and reasons why the studies do not apply.
Finland was probably the first to do autologous blood transfusions in 1972. Viren won the 5K and 10K (world record), Vasala beats Kip Keino to win the 1500M, and they won the Boston marathon and the World XC championships around this time. Then other countries discovered the secret and their competitive advantage vanished.
1972-B.Ekblum, et al. Response to Exercise after Blood Loss and Reinfusion. Journal of Applied Physiology.1972 Aug;33(2):175-80. publishes about hemoglobin changes and exercise performance changes after blood transfusions.
1976-Waldemar Cierpinski cheats to win the marathon gold medal for East Germany. Viren wins 5K and 10K gold again.
1980-Cierpinski again wins the marathon. Kaarlo Maaninka of Finland wins silver in 10k and bronze in 5k, and is found to have done blood transfusions.
1982-Francesco Conconi of Italy publishes journal articles about the anaerobic threshold, with variations on the CONCONI test being done today on runners and cyclists.
1984-Allberto Cova of Italy wins 10k Olympic gold. He did blood transfusions. Marti Vainio of Finland wins silver in 10k ,but is caught with the anabolic steroid metenolone, which was possibly in his old stored blood which he transfused before the race, but forgot he was on metenolone when the blood was withdrawn for storage. He was not a very smart doper.
It is also discovered that one third of the US Cycling team at the Olympics, which won 9 medals, were doing blood transfusions.
1985-blood transfusions are declared illegal and banned...but there is no test for detection.
1987-New England Journal of Medicine publishes a trial of recombinant EPO called Epogen, made by the biotech firm Amgen. Amgen ironically goes on to be a major sponsor of the cycling Tour of California, where many of the riders are using its EPO product.
1987 - 5 Dutch cyclists die.
1988- 2 Dutch cyclists die. 1 Belgian cyclist dies.

In this 1991 NYT article, John Tracey states:
"I began hearing about EPO two to three years ago through the grapevine in running circles," said John Treacy, a silver medalist in the 1984 Olympic marathon. "The story was there was this new drug that would take over from blood doping, and that it was much better."
1988- Dr. Francesco Conconi publishes a study on serum EPO levels in cross-country skiers.
https://www.ncbi.nlm.nih.gov/pubmed/3384528https://en.wikipedia.org/wiki/Francesco_Conconi1988-Salvatore Antibo from Italy wins Olympic silver in 10k and Gelindo Bordin wins the gold medal in the marathon. Bordin also wins Boston in 1990.
1989-Epogen approved by FDA for use in US.
1989-EPO moves into cycling in a big way. 5 more Dutch cyclists die.
1990- 2 more Dutch cyclists die and 3 more Belgian cyclists die.
1990- IOC bans EPO, but there is no test for detection of EPO.
1990-1991- track has 3 to 5 sub 13:10 5k perfomers and/or performances per year.
1991- Dr. Gabriele Rosa arrives in Kenya and sets up his first training camp.
1992- Dr. Eufemiano Fuentes of Spain (of later Operation Puerto fame) is a doctor in Spain as Fermin Cacho wins the 1500m at the Barcelona Olympics. Dieter Baumann wins the 5k and Khalid Skah wins the 10k.
1993-14 men break 13:10 a total of 21 times!!! while the Chinese women go on a rampage with Wang Junxia 29:31.78 10k WR, 8:06.11 3k WR, that still stand to this day. (New 29:17.45 by Alamaz Ayana in 2016. She is managed by Jos Hermens)
1993-2000-rampant EPO use. There is no test for detection and records are smashed, with huge depth of fast times by many people in track and cycling. Cyclists like Pantani and Riis pushing their hematocrits up to dangerous levels of 60 or 65%. Cycling finally institutes a hematocrit cutoff limit max hematocrit of 50% or you can't race and cyclists respond by basically all of them then having hematocrits of 48-49.5%, which is just a coincidence that they are all just below the limit...right?
A protege of the Italian Dr. Conconi, mentioned previously, went on to become much more famous. His name was Dr. Michele Ferrari, and he was the doctor to the stars of pro cycling. Ferrari was doctor to Lance Armstrong, who is the prototype for a pharmaceutical experiment gone mad disguised as an athlete. They did everything…EPO, transfusions, the anabolic steroid testosterone, Human Growth Hormone. What a name! You can't make this stuff up. The mad genius Dr. Ferrari really did turn his riders into Ferraris, with extra horsepower. He also did a great job making sure that 1) he kept Lance alive and didn't kill him and 2) that Lance somehow passed his drug tests. It was probably Ferrari that pioneered taking EPO by iv instead of subcutaneous injection, so that the EPO could be cleared faster, and the window for a positive epo test was then very small. Michele Ferrari is a very smart guy who is presently in trouble with tax authorities for hiding large amounts of money in secret bank accounts (which are not secret now), and he is also banned for life from cycling.
2000- the first urine test for EPO is developed and used at the Olympics. The test improved by around 2005..The new test for EPO leads athletes back to the old method of blood transfusions, to avoid detection.
2004-Italian Stefano Baldini wins gold medal in marathon. American Tyler Hamilton is caught doing a heterologous blood tranfusion of someone else's blood at the Olympics, where he won the gold medal. His B test at the Olympics had problems and he kept the medal on a technicality, but finally returned the medal in 2011. His lawyers used the famous "Tyler is a human chimera with a vanishing twin" defense to explain why he had blood from two different people in his bloodstream. Tyler wins the comedy prize for funniest doping excuse of all time.
2006- Operation Puerto with Dr. Fuentes and 211 bags of blood, anabolic steroids.
2008-CERA (Continuous Erythropoietin Receptor Activator) , a new longer acting agent, with a much longer half-life 20x longer than epo, is appoved for use in Jan, 2008 under the name Mircera. Rashid Ramzi tests positive for CERA at the 2008 Olympics, and loses his gold medal.
In conclusion:
There is nothing to see here.
