Lactic acid is a product of anaerobic respiration which accumulates in the muscles and contributes to the development of fatigue.
<h3>What is anaerobic respiration in muscles?</h3>
When a person is performing strenuous activity, they are utilizing a lot of energy. To maintain the energy supply, excess oxygen is needed.
But, sometimes, the oxygen supply becomes limited. In this case, the body adapts to lactic acid formation after the process of glycolysis.
Glycolysis results in the formation of pyruvate. During strenuous activities, the body begins anaerobic respiration which results in the formation of lactic acid.
Therefore, the accumulation of lactic acid results in fatigue and muscle cramps.
