Are they the same?

lactate (C3H5O3-) is the conjugate base of lactic acid (HC3H5O3), which is a weak acid

No, they are not the same, lactic acid functions as an acid, but lactate does not, because it does not release a proton (H+ Hydrogen ion)into solution.

Lactic acid production occurs nature and is a used in food production as a preservative. Lactate is produced in the muscles and this production has an alkalizing effect, reducing acidity by accepting a proton.

there's some suggestion that lactate is actually good for your muscles during working out. Contrary to popular 1920's oppinion that it is harmful.

as others posters have mentioned, in a strict sense they are different, but in everyday, running language they are usually used to refer to the same thing, i'd say. we do this with other acids as well, using aspartate and aspartic acid, glutamate and glutamic acid, acetic acid and acetate, etc interchangeably. (use the henderson-hasselbach equation to figure out which (acid or conjugate base) you have more of given different pH solutions. since the body is a buffered aqueous solution, it takes a LOT of lactic acid to change the blood's pH. most of the lactic acid produced becomes lactate and a proton, which is quickly gathered up by things like bicarbonate (mostly) or phosphate...)

but they aren't the same thing and most certainly affect how you run and how you feel differently.

I need to get up to date? You offer a REVIEW of older material that is itself several years old, and you dare suggest that I am the one needing to get up to date? Hah! Get your head out of the sand.

Is that all you got? Can you not refute what he had to say? Are we to believe all of your posts on this topic have been baseless?
