- Aerobic or oxidative energy system


Creatine Phosphate
CP


Anaerobic system
What system uses the ATP-CP system?


Anaerobic system

, Anaerobic system
- Operates without the use of oxygen
- Limited and inefficient

The difference between a person's measured or predicted maximum heart rate and resting heart rate


Anaerobic metabolism
- ATP created through a chemical reaction that does not require oxygen
- Activity so intense that the body cannot get oxygen to the muscles fast enough, so ATP is created
without it


ATP-CP Phosphagen System
Provides fuel for up to 10 seconds at maximal activity


Phase 1 of ATP-CP Phosphagen System
- Stored ATP
- Fuel for 1-2 seconds at maximal effort


ADP + P + Energy
ATP-CP Phase 1
- ATP splits into: ___ + ____ + _____
