Dependent Variables
1. Heart Rate (HR) – measured with 12 leads attached to an
electrocardiogram (ECG)
2. gen consumption O2) – measured from indirect
calorimetry
3. Rate of perceived exertion (RPE) – Borg Scale of 6-20,which is
a quantitative scale that indicates the intensity of exercise
4. Respiratory exchange ratio (RER) – indicates which substrate is
utilized and is measured from indirect calorimetry
5. Fat Oxidation (FO) – rate (g/min) at which fat oxidation occurs
during the exercise session
6. Peak Fat oxidation (PFO) – exercise intensity ( 2peak) where
peak fat oxidation is observed and is measured from indirect
calorimetry
