MUSCLE PHYSIOLOGY

Detailed explanation-1: -Lactic acid is formed and accumulated in the muscle under conditions of high energy demand, rapid fluctuations of the energy requirement and insufficient supply of O2.

Detailed explanation-2: -This burning sensation is associated with a buildup of acid in the muscles during intense exercise, and lactic acid has long been thought to be the culprit in that acid buildup, known as acidosis. Lactic acid is a byproduct of anaerobic metabolism, in which the body produces energy without using oxygen.

Detailed explanation-3: -What is lactic acid? Lactic acid, also known as lactate, is a substance the body produces mainly by the breakdown of glucose under anaerobic conditions (i.e., without oxygen), like anaerobic glycolysis.

Detailed explanation-4: -The extra oxygen you breathe in reacts with the lactic acid in your muscles, breaking it down to make carbon dioxide and water. As the lactic acid breaks down the cramps will begin to disappear.

Detailed explanation-5: -"It does build up in the muscle during exercise, and your muscle can be chock-full of it by the time you finish a strenuous workout, but generally all of this lactic acid is gone within about an hour afterwards.” Put simply, lactic acid clears out well before muscle soreness ever even begins.
