Answer :
The number of kcals used when a person who weighs 145 lbs, lifts weights for one (1) hour a day will be (b) 209 kcals.
The metabolic equivalent, or MET, is a crucial statistic that is used in this computation. The Compendium defines a "MET" as "approximately comparable to the energy cost of sitting quietly," which is 1 kcal/kg/hour. A 70 kg individual will burn 70 calories (kcal) in an hour of quiet sitting as one MET is equal to one minute of silence. The same person would burn 140 calories in an hour if the MET value of an exercise was 2.
You may calculate the number of calories expended per hour by multiplying the MET value by your weight in kilograms (MET*weight in kg). Divide the amount by two if you simply want to know how many calories you expended in a half-hour. If you want to know how long 15 minutes are, multiply it by 4.
I weigh 175 pounds, thus if I played competitive soccer for an hour with a MET value of 10, I would burn 79.38 kg*10 = 793.8 calories per hour.
