Answer #1

To calculate the net Energy Expended (EE), the energy expended to provide resting metabolic activities needs to be subtracted from gross EE.

Therefore, Net EE = Gross EE - resting EE

Gross EE = 487 kcals

resting EE for a person weighing 178 lbs (80.73 kg) is approximately 80.73 kcal per hour

for 31 minutes the resting EE will be (80.73/60) x 31 = 41.71 kcals

Therefore, Net EE = Gross EE - resting EE

                           = 487 - 41.71 = 445.3 kcals
