There's a couple more somewhere or other that I have somewhere.
The reason I'm a bit skeptical of the Weyand study you posted is because metabolically increased amounts of mitochondria contribute significantly to acid buffering which helps increase not only VO2max but also lactate threshold when trained correctly.
I'm going to reread it again to see if I get anymore out of it though. We'll see.
