Oxygen Debt Definition Anatomy

Oxygen debt definition is a cumulative deficit of oxygen available for oxidative metabolism that develops during periods of intense bodily activity and must be made good when the body returns to rest. What is oxygen debt.

The 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.

Oxygen debt definition anatomy. The amount of extra oxygen required by muscle tissue to oxidize lactic acid and replenish depleted atp and phosphocreatine following vigorous exercise. Purpose of elevated oxygen consumption. Difference between resting rate of oxygen consumption and elevated rate following exercise.

The excess oxygen goes into aerobic metabolism to generate atp. When you have a short intense burst of exercise such as sprinting you generate energy for this anaerobically or without oxygen. When you stop exercising you are still breathing heavily.

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

Refers to the fact that the breathing rate is much greater after vigorous exercise. Serves the elevated metabolic rate 2replenishes the phosphagen system 3. Oxidizes lactic acid produced by skeletal muscle.

To summarize these definitions oxygen debt is the amount of extra oxygen required by muscle tissue during recovery from vigorous exercise. Oxygen debt is a physiological phenomenon which occurs when someone has consumed oxygen at a rate faster than it can be replaced leading to a deficit in oxygen which causes increased respiration as the body attempts to replace the used oxygen. This is your body taking in extra oxygen to repay the debt.
