A quote from the Form and Fitness Q & A at www.cyclingnews.com:
Dave Fleckenstein:
"Max Testa (one of the world's top exercise physiologists who at one point was working with 35 of the top 50 UCI ranked cyclists) recently completed a study at his lab on cleat position and efficiency and clearly found (p<.001) that as the cleat moves posteriorly cyclists are more efficient. I am not sure as to the publication date for the study but know that it is pending."
My comment: I'll believe it when I see it, since 1) contrary to what is asserted, Dr. Testa is not recognized as one of the world's top exercise physiologists because he has never published in a scientific journal before (so why start now?), and 2) I am aware of at least four other studies (one theoretical, three experimental) which found no impact of cleat position on efficiency.
