how are oxygen deficit and oxygen debt affected by exercise

how are oxygen deficit and oxygen debt affected by exercise intensity and duration ?

Solution

Oxygen deficit: is the difference between the total oxygen actually consumed during exercise and the total oxygen required (consumed) in steady-rate from the start of exercise. As begin exercise, not producing enough oxygen to do work. Then, the body borrows on its energy reserves (credits). After exercise, the body tries to pay back those credits plus some interest.

Oxygen debit: After exercise, oxygen consumption does not return to resting levels immediately. Then, the extra oxygen consumed during recovery, above a resting baseline is called Excess Postexercise Oxygen Consumption (EPOC). EPOC is also termed O2 debt. Oxygen consumption remains elevated following exercise Classical term-oxygen debt - Depends on intensity and duration of activity
