ANATOMY

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. During intense exercise sustained to fatigue muscle pH decreases to about 6.4-6.6.

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.

Detailed explanation-3: -Lactic acid is a chemical your body produces when your cells break down carbohydrates for energy. You might see it referred to as lactate. Muscle cells and red blood cells make the most lactic acid, but it can come from any tissue in your body. Most people think of lactic acid in their muscles during a tough workout.

Detailed explanation-4: -Accumulation of lactic acid in the muscles causes cramps.

Detailed explanation-5: -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.
