Detailed explanation-1: -Answer and Explanation: Muscle soreness associated with strenuous exercise is at least partly due to the presence of lactic acid produced during fermentation in muscle cells. Lactic acid is produced during strenuous exercise because the demand for ATP exceeds what mitochondria can supply.
Detailed explanation-2: -Lactic Acid Buildup Causes Muscle Fatigue and Soreness. Anyone who has pushed themselves through an intense workout will be familiar with “feeling the burn”-that sensation of fatigue and pain that sets in when you subject your muscles to lifting heavy loads repeatedly or sprinting all-out.
Detailed explanation-3: -Lactic acid and exercise Neither lactic acid nor lactate are responsible for muscles soreness or burning sensations from 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: -Complete Answer:-During strenuous exercise, our muscle cells run short of oxygen, as a result they breakdown the glucose to lactic acid anaerobically. When lactic acid builds up, gradually, it leads to muscle cramps and muscle fatigue.
Detailed explanation-5: -Lactic Acid Fermentation in Muscle Cells Your muscle cells can produce lactic acid to give you energy during difficult physical activities. This usually happens when there is not enough oxygen in the body, so lactic acid fermentation provides a way to get ATP without it.
