Question

Quizplus · Accepted Answer

The MET (metabolic equivalent of task) is a unit used to express the energy expenditure of physical activities. One MET corresponds to the resting metabolic rate, which is about 3.5 ml of oxygen per kilogram of body weight per minute.

If a subject is performing a 10-MET activity, it means that they are expending energy at 10 times their resting metabolic rate. Therefore, their oxygen consumption would be:

10 METs x 3.5 ml of oxygen per kilogram of body weight per minute = 35 ml of oxygen per kilogram of body weight per minute

This value is independent of the duration of the activity.
