debt

 [det]
something owed.
oxygen debt the extra oxygen that must be used in the oxidative energy processes after a period of strenuous exercise to reconvert lactic acid to glucose and decomposed ATP and creatine phosphate to their original states.

ox·y·gen debt

the extra oxygen, taken in by the body during recovery from exercise, beyond the resting needs of the body; sometimes used as if synonymous with oxygen deficit.

oxygen debt

n.
The amount of extra oxygen required by muscle tissue during recovery from vigorous exercise.

ox·y·gen debt

(ok'si-jĕn det)
The extra oxygen, taken in by the body during recovery from exercise, beyond the resting needs of the body; sometimes used as if synonymous with oxygen deficit.
Synonym(s): excess postexercise oxygen consumption.

oxygen debt

a state that arises in very active muscles when insufficient oxygen is supplied by the lungs, causing the muscle tissue to respire anaerobically with the production of LACTIC ACID. When muscular activities slow down, the rate and depth of breathing remains at a high level until the lactic acid has been oxidized. Oxygen debt can be measured as the difference between the amount of oxygen required after strong muscular activity and the amount required in a resting state. In trained athletes, the debt can be as high as 18 litres of oxygen.
