## How to calculate calories (burned)

The number of calories you burn while exercising is dependent on:

• the exercise you do
• the time spent doing the activity

By multiplying the body weight in kg by the MET (*) value and duration of activity, you can estimate the energy expenditure in Kcal specific to a persons body weight. In this example, rollerblading at 17.7 km|h at a 9.8 MET value, burns 9.8 Kcal/kg x body weight/h.

A 70 kg individual rollerblading at 17.7 km|h for 30 minutes expends the following:

(9.8 METs x 70 kg body weight) x (30 min/60 min) = 343.0 Kcal.

9.8 is the value in METs for rollerblading at 17.7 km|h.
