Only used ACSM Equations / Metabolic Calculations and Conversions.

Mr. Smith weighs 180 lb and is walking at a 3% incline on a treadmill at an intensity of 5 METs. Determine Mr. Smith's net energy expenditure (kcal) during each minute of walking.

Answer 1

The equation to calculate the energy expenditure per minute is given below:

Expenditure of energy (in calories) per minute = (MET x 3.5 x body weight in Kg) / 200

MET stands for metabolic equivalents of task and is a measure of the amount of oxygen the person is burning when using treadmill. One MET represents the energy expenditure while at rest. One MET is equal to 3.5 mL/min/kg of body weight.

Here,

MET = 5

MET value 5 represents that the person is using five times more the energy for the activity as compared to the energy expenditure while at rest.

Body weight = 180 lb = 81.6466 Kg

Substituting the equation with these values:

Expenditure of energy in calories per minute = (5 x 3.5 x 81.6466) / 200 = 7.14 Calories = 0.00714 kcal

Therefore, Mr. Smith's net energy expenditure (kcal) during each minute of walking is 0.00714 kcal
