MEDICAL 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: -Lactic acid is fuel for your cells during intense exercise. It’s created when your body breaks down glucose and other carbohydrates.

Detailed explanation-4: -What does lactic acid do? Lactic acid is formed within the muscle cells during glycolysis to clear the cells of accumulating pyruvate, a by-product of glycolysis. While still in the muscle cells, the hydrogen ion is what is responsible for lowering the pH of the muscle tissue, making it more acidic.

Detailed explanation-5: -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.
