Exercise bioenergetics (definition)
The food energy we consume (carbohydrates, fats, and protein) must be converted into biologically usable energy
What is the only source of energy for our cells?
Adenosine triphosphate (ATP)
Energy is stored in chemical bonds
When is energy released?
Energy is released when the bond is broken; during activity
Without adequate ATP, all cellular activity would stop
Problem: our supply of ATP is extremely limited
10-15 seconds of maximal exertion
