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: -"Muscle soreness occurs because muscle and the connective tissue around it get damaged during exercise, ” explains Dr. Hedt. “This is completely normal and nothing to worry about, though. In fact, it’s needed for muscle growth, since muscle is built back stronger during this repair process."

Detailed explanation-3: -Lactic acid and exercise In fact, lactic acid is an important fuel source for muscles during exercise, including those in the heart. Muscle soreness after exercise occurs due to microdamage to muscles.

Detailed explanation-4: -Does lactic acid or lactate cause muscle soreness? Although the drop in cellular pH results in the temporary burn during intense sets, lactic acid is not responsible for the delayed onset muscle soreness (DOMS) that often follows intense exercise.

Detailed explanation-5: -The most common causes of muscle pain are tension, stress, overuse and minor injuries.
