Question
'Oxygen debt' is associated with man during
Correct Answer
Option B is the correct answer.
Detailed Explanation
Oxygen debt (now more accurately called Excess Post-Exercise Oxygen Consumption or EPOC) occurs during and after strenuous exercise when the body's demand for oxygen exceeds the supply. This leads to a relative anaerobic state where muscles respire anaerobically, producing lactic acid. After exercise, extra oxygen is needed to metabolize the lactic acid and replenish energy stores.
Hint
When does the body resort to anaerobic respiration due to oxygen not reaching muscles fast enough?
