I'm doing a research project testing lactate threshhold and power output. In my background search and on this forum I'm seeing research by someone named Groves (discoverer of the lactate shuttle) that says lactate is a fuel. I always thought it was the enemy - or is it both? Anyone know if lactate is a fuel at low intensities, but at higher intensities it remains a fuel but reaches a point where it shuts the muscle down? Thanks.

George Brooks in 1984 - not Groves.

That's the idea, but read the posted article.

Which posted article would that be?

complete with powerpoints. oh joy.

*nvm, that's just Brook's profile. Google dude - look at google's scholarly tool too. There's gotta be some good scientific research on it.

I actually googled some last night and found this illuminating and seemingly well-referenced.
