E1-E6 Energy Systems

Open Ended

You, the coach/analyst: Explain how a team in the Premier League could exploit a team in League one's Energy Systems.

Multiple Choice

How do intensity and duration of an activity influence the way energy is provided in the body?

• Intensity determines the speed of energy use, while duration affects the total energy required.

• Intensity and duration have no effect on energy provision.

• Only duration affects energy provision, not intensity.

• Only intensity affects energy provision, not duration.
