How many calories do i burn playing tennis for 30 minutes 154.3 pounds or 70 kilograms
How to calculate calories (burned)
The number of calories you burn while exercising is dependent on:
- the exercise you do
- your weight
- the time spent doing the activity
By multiplying the MET (*) value by the body weight in kg and the duration of the activity, you can estimate the energy expenditure in Kcal specific to a person's body weight. This statement can be expressed as the following formula:
In this example, playing tennis at a 7.3 MET value, burns Kcal/kg x body weight/h.
So, a 70 kg individual playing tennis for 30 minutes expends the following:
(7.3 METs x 70 kg) x (30 min/60 min) = 255.5 Kcal.
- 7.3 is the value in METs for playing tennis
- The time unit is expressed in minutes
- The mass (weight) unit is expressed in kilograms
- We divide the time by 60 (min) because the MET unit uses hour.
(*) MET means 'metabolic equivalent'
