Detailed explanation-1: -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-2: -Lactic acid is mainly produced in muscle cells and red blood cells. It forms when the body breaks down carbohydrates to use for energy when oxygen levels are low. Times when your body’s oxygen level might drop include: During intense exercise.

Detailed explanation-3: -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: -Lactic acid accumulates in your muscle cells as fermentation proceeds during times of strenuous exercise. During these times, your respiratory and cardiovascular systems cannot transport oxygen to your muscle cells, especially those in your legs, fast enough to maintain aerobic respiration.
