The Metabolic Equivalent of Task (MET), or simply metabolic equivalent, is a physiological measure expressing the energy cost of physical activities and is defined as the ratio of metabolic rate (and therefore the rate of energy consumption) during a specific physical activity to a reference metabolic rate, set by convention to 3.5 ml O2·kg−1·min−1 or equivalently this is described by Harvard School of Public Health.
MET values
MET values change according to the movement type. Depend on the physical activity type change the MET value. Table 2 shows sample MET values of sample physical activity types.
