Cathy Freeman’s 400m sprint would predominantly use which energy system?

• Aerobic system

• ATP-PC system

• Anaerobic Glycolysis system

• All of the above

The aerobic system is ...

• The slowest system to contribute towards the resynthesis of ATP

• The only system with one fuel source

• The same as the lactic acid system
