Anatomy and Physiology for Sport: Energy Systems
Content and assessment criteria
● Rate of ATP used by each system
● Fuels used by each system
● By-products of each system
● The contribution of each system
● The contribution of each system in different sports/activities
ADENOSINE TRIPHOSPHATE (ATP)
● The body’s main energy currency
● Chemical substance
● Limited stores, has to be re-made
● Broken down to create energy for all body processes
● Energy is produced when the bond between phosphates is broken
ATP= 3 PHOSPHATES
ADP=2 PHOSPHATES
The Mitochondria are where the Energy is produced. They are the power plants of cells.
There are 3 main energy systems
● Creatine Phosphate System (C.P. System) Anaerobic
This is the immediate source and works without oxygen
● Lactic Acid System (Anaerobic glycolysis system) Anaerobic
This kicks in at the end of the CP System and works without oxygen
