Pat Quinn and Lactic Acid

Print"That shift killed one of our players (Comrie) because his play dropped off the rest of the night. A lot of times, you blow the tank when you get caught out in a bad spot, then you can’t seem to pull the reserve up. If you get into a lactic thing … here I am trying to sound like an (expert). I do read all that stuff, though."
--Pat Quinn, on the Mike Comrie running out of gas against Calgary.
Bruce had a note on this yesterday in the FanPosts section. Pat should read up on the latest concerning lactic acid. Comrie was tired, but it wasn't a "lactic thing" that did him in.
Lactic acid is actually a fuel, not a caustic waste product. Muscles make it deliberately, producing it from glucose, and they burn it to obtain energy. The reason trained athletes can perform so hard and so long is because their intense training causes their muscles to adapt so they more readily and efficiently absorb lactic acid.
and...
Through trial and error, coaches learned that athletic performance improved when athletes worked on endurance, running longer and longer distances, for example. That, it turns out, increased the mass of their muscle mitochondria, letting them burn more lactic acid and allowing the muscles to work harder and longer.
Pat Quinn may have an excuse though, also from the article:
"They said, 'You're anaerobic, you need more oxygen,' " Dr. Brooks said. "The scientists were stuck in 1920."

The lactic thing and the pubis thing are killing us this year.

Lots of health things going on here.

Well, to be clear, as I said in the comment to the fanpost, the lactate (La-) is the fuel, but the acid (H+) is what does you in, by inhibiting muscular contraction and glycolysis. The better you can buffer the acid in your blood (and subsequently blow it off as CO2), the better off you are. Aerobic training enhances your ability to consume lactate (and presumably, how much CO2 you can blow off, and thus how much blood acid you can get rid of), while anaerobic training enhances your ability to sequester acid in the blood, at least as I understand my class notes here.
