Metabolic equivalent of task
Metabolic Equivalent of Task (MET)
The Metabolic Equivalent of Task (MET) is a physiological measure expressing the energy cost of physical activities. It is defined as the ratio of metabolic rate during a specific physical activity to a reference metabolic rate, set by convention to 3.5 ml O2·kg−1·min−1, which is roughly equivalent to the energy cost of sitting quietly.
Pronunciation
Metabolic Equivalent of Task: /mɪˈtabəlɪk ɪˈkwɪvələnt ɒv tæsk/

The term "Metabolic Equivalent of Task" is derived from the field of exercise physiology. "Metabolic" refers to the biochemical processes involved in the body's normal functioning. "Equivalent" refers to the comparison of the energy expenditure during different activities, and "Task" refers to the specific physical activity.
