State that lactic acid builds up in muscles and blood during vigorous exercise causing an oxygen debt
Answer
During vigorous exercise, lactic acid builds up in muscles and blood due to anaerobic respiration, which occurs when the demand for energy exceeds the oxygen supply. This process leads to the incomplete breakdown of glucose, resulting in the production of lactic acid.As lactic acid accumulates, it creates what is known as an oxygen debt. This term refers to the increased need for oxygen after exercise to metabolize the accumulated lactic acid and restore the body to its resting state. Consequently, individuals often experience heavy breathing and an elevated heart rate even after the exercise has stopped, as the body works to repay this oxygen debt and clear the lactic acid from the system
