Exercise 5

Compute the estimated energy expenditure (ml • kg?1 • min?1) during horizontal treadmill walking for the following examples:

a. Treadmill speed = 50 m • min?1

Subject’s weight = 62 kg

b. Treadmill speed = 100 m • min?1

Subject’s weight = 75 kg

Step 1 of 5

Measurement of energy expenditure is particularly useful in certain areas like exercise assisted weight-loss programs. Energy expenditure is measured in terms of oxygen consumed, in litres per minute or ml.kg^-1.min^-1. Expression of energy expenditure in terms of ml.kg^-1.min^-1 facilitates comparison of energy expenditure among people of different body sizes.
