I wanted to see what new information you guys (and girls) had on Lactic Acid, as it is being researched more and some facts seem to be emerging from the old information. I would appreciate any insights you all have, the more physiology the better. Here are some questions, I think I know the answer to a few of them but wanted to see what you all had to say about them.
Is Lactic Acid what makes your muscles burn? If not, what does?
Is Lactic Acid what makes your muscles sore? If not, what does?
Does a build up of too much lactic acid lead to muscular failure?
Is lactic acid a waste product or fuel or both?
Is there an important difference between lactic acid and lactate?
Is the Fast Glycolysis energy system the only system that produces/uses lactic acid?
Finally, does the new stuff we are learning about lactic acid have any practical effect on the way we should train to improve performance?
Thanks for your thoughts
