Muscle Burning is NOT Lactic Acid
If you've been exposed to athletics or exercise, you've likely heard the term "lactic acid build up in muscles" as the cause for that deep muscle "burn". Well, this isn't true...
We've long told folks that the deep muscle burn that they feel when exercising and during athletic pursuits is due to lactic acid build up in our muscles. This claim started in the 1920's when scientists discovered that there were high amounts of lactic acid in severed frog legs that were forced to twitch to exhaustion using electrical stimulation. Later, research concluded that there were high levels of lactate present in human muscle during hard bouts of exercise, concluding that muscle fatigue was due to lactate build up.
This was a classic science mistake of assumption. Fast forward and fact check: this isn't true. And yet, it's the story that continues to circulate when this myth has been debunked for decades.
For the folks who just want to know the answer behind that muscle fatigue burn while exercising, the answer is: scientists still don't 100% know. Whomp, whomp. The hypotheses: excess hydrogen ion accumulation and/or it's nervous system driven as a protective mechanism to avoid excessive muscle damage
