Lactic Acid and Muscle Burning Pain
Muscle burning pain appears to be the sign of lactic acid activity in muscles. Is the following situation familiar to you: you perform numerous Barbell Curls and your arms start burning; it becomes so painful that you have to stop doing the exercise? Why does it happen? Is lactic acid our fried or foe?
You should remember that muscles can restore their energy supply by different means: both using oxygen (aerobic way) and without it (anaerobic way) when glycogen supply turns into ATP molecules that our organism requires. Exactly this way leads to lactic acid production performed by our muscles. In a normal state of our organism lactic acid is removed from muscles with the help of blood rather quickly; during workout, however, the bloodstream in an engaged muscle is hampered (blood is pumped in the muscle and doesn’t leave it); and lactic acid can remain in the engaged muscle for long enough to cause burning sensation.
