You don't understand how oxygen delivery works. But neither does the professor you quote.
The" more oxygen, more power the fastery you go" scenario works perfectly well with normal blood counts. The idea that more red blood cells than normal will deliver more oxygen and more power is ridiculous. If it was true then the body would produce more red blood cells wouldn't it?
Jack Daniels 1979 paper 'OXYGEN POWER' makes equally spurious claims, which he must be emabarassed about today, he actually said in that paper that running was not a skill.
What surprises me is not how fast Barega ran, but how long it has been since someone ran a fast time. Conditions and pacemaking made a big difference.
Barega's energy output would have been lower in that race than in a slower race. This is something you drug obsessives don't understand. The trend towards faster times will result from a trend of less total energy ouput, i.e. better biomechanical efficiency. And I repeat: we all have a bioenergetic limit to energy output intensity which no drug can circumvent because we are limited within the bound of heat production. No such boundary for efficiency in distance running has been idenfified.
With a remark like that why bother reading any of your posts anymore.
Professor Carsten Lundby, PhD physiologist, is one of the world's leading experts on the effects of EPO on the human body and has co-authored numerous papers:
I am well aware of the studies. I have been aware of EPO doping since 1991
From then on I learned about altitude training and natural erythropoiesis in the naieve belief that more red blood cells = more oxygen delivery.
Since then, it became obvious why this belief was naieve; a healthy body prodces the right amount and more red blood cells can't do what he says:
"When haematocrit is increased from base values to around 50%, An external file that holds a picture, illustration, etc. VO2 max is increased by 8–12%
Sorry but that is nonsense. It is simply not possible because then you would have a massive increase in heat accumulation, which is physically impossible. It is a bioenergetic impossiblity, a thermoregulatory impossibility.
Here is a more rational explanation: VO2 max tests are only as reliable as the lab technicians are competent.
In othere words you will see a wide variablity in test results for the same person. Barega and Kajelcha running on a cool evening could utilize more oxygen than on a warm afternoon because that is the normal response to running in cooler weather; more oxygen is taken up by the skeletal muscles. In warmer conditons, more blood goes to the skin for cooling and oxygen uptake is lower, sometimes a lot lower.
Now back to my point about Lance Armstrong's fictitious power outputs. The mythological 6.97 watts per kilo ascent of Alpe d'Huez is the oft quoted epitome of EPO doping. Ask any cyclist how much power he would really need to ride up an 8.3% grade at 22kmh? It is far below the puported figure. So why does the figure get bandied about so much? Because false data is used to support false beliefs.
You have to realise that Lance's coach Michele Ferarri was using made up numbers too, as kidology, telling him his EPO 50 hematocrit 'threshold' was 6.7 watts per kilo. When you study his performances, you will see it was around 6.0 watts per kilo and that the 6.7 was Lance's VO2 max power. These are normal number for elite cyclists. Read Tyler Hamilton's book. His supposedly supercharged performance level was actually by his own numbers (5.9 watts per kilo for 32 minutes) a normal power output.
But am I wasting time debating this with you and others. Is it like debating against a religious dogma where science is irrelevant to you and belief is what matters?
An 18 year old Ethiopian runs a 12:43 and the reaction over overwhelmingly negative. A 17 year Norwegian runs 3:31 and it's like Christmas here. Can anyone explain that?
That's because a 12:43 is far superior than a 3:31.
IAAF scoring tables says a 3:31 is the equivalent to a 12:54. The equivalent to a 12:43 is 3:28. HUGE DIFFERENCE. Plus, as constantly pointed out, nobody runs under 12:50 anymore (let alone 13:00), while is 3:31 is comparatively common.

Doesn't 3:31 guys come a dime a dozen in Kenya? But 12:43? Holy Bat Gas!...that's freaking flying! ?What a full-throttle performance by the youngster.

It's basic physiology. Thermoregulation. Look it up.
Believing that you can magically increase your oxygen uptake by having a stupidly high hematocrit is beyond bad science, it's appalling bad science.
And I repeat, those EPO doped cyclists were producing normal power outputs, not superhuman efforts.
22kmh on an 8.3% grade is 6 watts per kilo not 7
Get Ross Tucker on here to debate the issue with me. I'm not going on twitter.
Real science, not pretend science. Put up or shut up.
I would like to point out how power outputs actually work for cyclists. Just making up numbers is not acceptable but seems to have been the norm 10 years ago.
Ross Tucker actually leaves some of the questions open for debate, in case you hadn't noticed, so he's not completely subservient to dogma.
Hehe. Had a chuckle at this one. Not only that though, Fisher has been running close to 10 seconds faster than Barega....and was faster than all Ethiopians last year

Lmaoooooo that’s only because barega has to peak twice. First he has to earn his spot against other world beaters not an easy task…
