In physiology, a metabolic equivalent, or MET, is defined as the ratio of a person's metabolic rate during an activity relative to their basal resting metabolic rate. One MET then is the amount of energy needed to sit quietly.[1][2] More specifically, 1 MET is resting or basal oxygen consumption (VO2) of a 70-kg, 40-year-old man. One MET is 3.5 mL per kg per min.
As an example, walking quickly (3 to 4 miles-per-hour) requires 4 METs.
In a stress test using the Bruce Protocol, stage 1 is 4.8 METs and stage 2 is 7.0 METs.[1]

- Canadian Cardiovascular Society criteria
- The Duke Activity Status Index[3][4]
- The Specific Acitivity Scale[5]
