OCR A level PE - Energy Continuum

What is the definition of the energy continuum?

• The point where the predominant energy system switches from one to another.

• A model that shows the % contribution of each energy system to ATP resynthesis.

• Exercise where the intensity repeatedly varies between maximal to submaximal to rest.

• The maximum volume of oxygen that can be used by the body in 1 minute.

Which energy system is predominant during high intensity, short duration exercise?

• ATP-PC
