Forums >General Running>Power Running Physiology Enters the Mainstream
Viich, As I noted earlier, I've never thought my training recommendations were particularly radical but some folks really get bent out of shape about them and the research data supporting them. You can see clear evidence of that in the last 2 pages of this thread.

More excerpts from Run Faster Running Economy "The term 'running economy' refers to the energy cost of running at a given speed. Reducing the energy cost of running at your goal pace will help you sustain that pace all the way to the finish line." A while back I wrote an article making this very point - running economy is about energy use, not oxygen consumption. Therefore, when running economy improves it means the amount of energy you are burning at any particular pace is less. I propose that one of the main reasons that energy usage declines is because the muscle fibers have become more powerful. More powerful individual muscle fibers means fewer overall muscle fibers have to be activated to run at any particular pace.

I've descovered that he has NO interest whatsoever, and he has said it himself, with running or training at all. He is interested in theories. And good for him for that. But I really don't think his theories has any use to those who run or those who are interested in improving their training/performance.
I've never said or implied any such thing. Why would you spread such a lie?
The topic of this thread is "physiology" not "training" because the book and I agree on some physiological points related to muscle, not training methods.

Linus got new glasses. Charlie Brown asked: "Oh, you got new glasses? Are they for near-sighted or far-sighted?" Linus said, "Which is which?" Charlie Brown goes, "Well, which is which... Is near-sighted when you can see... Wait. Is it far-sighted when you can see..." and goes on and on and on... Linus finally said, "I wear glasses so I can see better," and walked. away
People want to believe that quality trumps quantity because they won't or can't put the time in.

In 1999, for example, he showed that endurance training reduces blood levels of lactate, even while cells continue to produce the same amount of lactate. This implied that, somehow, cells adapt during training to put out less waste product. He postulated an "intracellular lactate shuttle" that transports lactate from the cytoplasm, where lactate is produced, through the mitochondrial membrane into the interior of the mitochondria, where lactate is burned. In 2000, he showed that endurance training increased the number of lactate transporter molecules in mitochondria, evidently to speed uptake of lactate from the cytoplasm into the mitochondria for burning.
