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.

oxygen debt

the quantity of oxygen that the lungs take up during recovery from exercise or apnea that is in excess of the quantity needed for resting metabolism before the exercise or apnea. Oxygen debt represents replenishment of the oxygen store that was depleted during the time that oxygen uptake from the air was inadequate for aerobic metabolism. See also oxygen consumption.

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.

oxygen debt

amount by which oxygen consumption during recovery from exercise exceeds resting level. Consists of an initial rapid phase lasting ∼1-2 min (formerly called the 'alactic' phase), in which muscle CrP and ATP stores are replenished, and a subsequent slow phase (∼1 h) in which lactic acid is oxidized (hence the former term 'lactacid' phase), temperature falls toward resting level and blood hormonal concentrations are normalized. Also known as elevated post-exercise oxygen consumption (EPOC) or recovery oxygen consumption.

oxygen debt

oxygen taken in during recovery from exercise, over and above the immediate needs

debt

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.
