Oxygen Debt

What is the definition of oxygen debt?

• Amount of oxygen used for aerobic activity minus amount of oxygen actually used

• Amount of oxygen needed at the end of a physical activity to break down any lactic acid

During oxygen debt, the lactic acid is removed from

• Liver

• Muscles

• Lungs

• Heart

In order to recover the fatigue, the lactic acid is...

• taken to muscles

• taken away from muscles

• converted to galactose

• converted to glucose

An oxygen debt occurs in muscles when...

• more carbon dioxide has been produced

• the breathing rate increases

• anaerobic respiration has taken place

• the pulse rate increases

The extra oxygen needed is to oxidise lactic acid into...

• carbon dioxide and oxygen

• oxygen and water

• carbon dioxide and water

• carbon dioxide, water and oxygen

To repay the oxygen debt, we need to take in deep, gasping breaths at the end of physical activity

• True

• False

The extra oxygen breathed in is to (multiple answer)

• maintain higher than resting breathing rate, heart rate and temperature

• remove excess carbon dioxide from the body

• gradually decrease body temperature

• break down and oxidise lactic acid.

What does EPOC stand for?

• Extra Post-exercise Oxygen Consumer

• Excess Post-exercise Oxygen Consumption

• Extra Post-exercise Oxygen Consumption

• Excess Pre-exercise oxygen consumption

A good way to recover from from activity is to...

• rehydrate

• refuel with food

• cool down

• ice bath
