Ooooooh the BURN!


The long held belief that, the burning sensation you feel in your muscles is due to lactic acid accumulation, is DEAD WRONG. Dead... like George Washington dead.

In fact, we don't even produce lactic acid we produce lactate. And lactate is an energy source that helps us fight off fatigue under intense exercise conditions.

So what produces the burning sensation? I'm glad you asked!

The energy source for muscle contractions is ATP (adenosine triphosphate). When we breakdown ATP a hydrogen ion is released. Hydrogen affects our muscle pH by making it acidic.

At higher exercise intensities hydrogen ions accumulate in the working muscle causing it to become acidic--resulting in "the burn."

So next time you hear someone blaming poor lactic acid for something it didn't do you can point them to the real culprit, hydrogen.
