The chemistry of the burn

I get a lot of my exercise science news via Alex Hutchinson of the Sweat Science blog on RunnersWorld.com. For instance, this nifty item about “the burn” of intense effort — what exactly causes it? Which molecules?

According to Pollak et al, it’s protons, lactate, and ATP — and only in concert. “There was essentially no response whatsoever to the individual metabolites,” explains Alex, “so the receptors apparently respond only to the synergistic combination of all three.”

Surprisingly, this fairly unsurprising result is brand new information: the paper’s authors call it “the first demonstration in humans that metabolites normally produced by exercise act in combination to activate sensory neurons that signal sensations of fatigue and muscle pain.”

See Alex’s post on Runner’s World for some more detailed analysis. Here on SaveYourself.ca, I’m citing the Pollak paper in my delayed-onset muscle soreness article.

Rich Roll, who was ranked as one of the world's fittest men, has some important insight on the cultural fixation with protein. "The animal protein push is not only based on lies, it’s killing us." Please read Rich's article: http://www.forksoverknives.com/slaying-protein-myth/
