Physical Education - Oxygen debt

Oxygen debt

* O2 debt [1]

When you finish exercising, energy demands decrease. However, the amount
of oxygen required by the body remains above resting levels. This is known
as oxygen debt.

There are two components:

- refers to the restoration of PC stores (complete in only 3 minutes).

- refers to the removal and breakdown of lactic acid from the muscles
and blood. This takes much longer - approximately 2 hours.

What is the time taken for PC replenishment (what is the role of oxygen
system here)?

70% - 30 seconds

90% - 90 seconds

100% - 3 minutes
