Detailed explanation-1: -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-2: -Lactic acid is created when the body turns glucose into energy. The production of lactic acid occurs when oxygen levels are low, generally during high-intensity exercise. Lactic acid build-up can hinder your exercise routine, so it’s important to understand why it happens and how to prevent it.

Detailed explanation-3: -Lactic acid is produced when oxygen levels become low in cells within the areas of the body where metabolism takes place.

Detailed explanation-4: -When you run fast there is a chemical reaction called anaerobic respiration. This reaction transfers energy from glucose to your cells without oxygen. There is just one waste product called lactic acid.

Detailed explanation-5: -Lactic acid or lactate is produced during fermentation from pyruvate by lactate dehydrogenase. This reaction, in addition to producing lactic acid, also produces nicotinamide adenine dinucleotide (NAD) that is then used in glycolysis to produce energy source adenosine triphosphate (ATP).
