Aerobic Exercise

The formula for Aerobic Exercise is Glucose + Oxygen ---> Energy + Carbon Dioxide + Water

Aerobic Exercise is...

- With Oxygen. When the exercise is not too fast and is steady , the heart can supply all the oxygen that the working muscles need.

The demand for oxygen in the muscles is met by the supply from the heart.

For example: Long distance running, swimming or walking.

Anaerobic Exercise

The formula for anaerobic exercise is Glucose ---> Energy + Lactic Acid

This is exercise without oxygen and is used in short durations at high intensity.

The build-up of lactic acid in muscles causes pain and fatigue. The muscles cannot work efficiently. Exercise will have to slow down or stop if too strenuous- No more than 60 seconds.

E.G Sprinting, shot put and triple jump.

EXCESS POST-EXERCISE OXYGEN CONSUMPTION

The amount of oxygen needed to recover after anaerobic exercise

​​​​​​​The increased breathing rate and depth of breathing supplies the body with oxygen, which is used to remove lactic acid.
