Energy Transfer in the Body
Adenosine triphosphate (ATP) - The energy currency.
Powers all of cells energy requiring processes.
Potential energy extracted from food.
Energy is stored in bonds of ATP there is a limited
Energy Transfer in Exercise
Immediate Energy: ATP-PCr
Technically, this is an alactic system
We store far more PCr than ATP partly because ATP is such
a heavy molecule
There might be enough stored ATP to sustain maximal efforts
of 4-8 seconds
Human Energy Expenditure During Rest and
Energy Expenditure at Rest
Total Daily Energy Expenditure (TDEE):
1. Resting Metabolic Rate (60-75%)
2. Thermogenic Effect of Food Consumed (~10%)
3. Energy expended during PA & reco
