Answer
Lactic Acid
Explanation
During vigorous exercise, when the body's demand for energy exceeds the oxygen supply, the muscles switch to anaerobic respiration. Here, glucose is converted into lactic acid, which is a by-product of this anaerobic pathway. Build up of this waste product can influence muscle function and lead to fatigue and pain.
