Definitions for "Metabolic equivalent"
A unit used to estimate the metabolic cost (oxygen consumption) of physical activity. One MET equals the resting metabolic rate of approximately 3.5ml O2.kg-1.min-1
A way of measuring physical activity intensity. This unit is used to estimate the amount of oxygen used by the body during physical activity. (Ainsworth, 1993). 1 MET = the energy (oxygen) used by the body as you sit quietly, perhaps while talking on the phone or reading a book. The harder your body works during the activity, the higher the MET.
A MET or metabolic equivalent is a way of expression the rate of energy expenditure from a given physical activity. 1 MET equals oxygen consumption at rest which is about 3.5 millilitres per kg of body weight per minute. An individual exercising at 2 METS is consuming oxygen at twice the resting rate.
