Lactic acid as a fuel source?

Some interesting research out of Berkeley:

Lactic acid as fuel?

From what I can tell, so far, this doesn't change much in the world of training too much. You still need to train in the aerobic realm to enable oxygen transport and in the glycolytic pathways for anaerobic endurance, which will come down to your Kreb's Cycle efficiency. It's just that now, perhaps, we've got different terminology for what is actually happening in the body. But perhaps this understanding will somehow revolutionize training once it's fully understood. Anyway, it's always great when new research--especially stuff that breaks the mold of what we 'know'--comes out.

What could be more fascinating? Truly. Don't you just love science?
