kg -1.min -1= 5.5 METs (moderate intensity)
kg -1.min -1) obtained from indirect calorimetry. kg -1.min -1) and a measured value (2.5 ml. Two values were used for the RMR: the standard value (3.5 m ml. 10 used the following example to demonstrate their point to compute the MET value for an activity with a measured VO 2 of 20 ml. kg -1.min -1 as the RMR referent value to compute METs underestimates the true energy cost of physical activities obtained when using a measured RMR. Critics argue the Compendium’s use of ml. kg -1.min -1 as a proxy value for the RMR because of its potential to overestimate measured RMR values that are less than 3.5 ml. Recently, there has been concern about the accuracy of using 1 MET = ml. It does not correct the MET levels for age, body mass, and sex. The RMR is higher in men than women and increases with height, weight, and lean mass and it decreases with age 2.ĭeveloped in 1989 and published in 14, and 2011 5, the Compendium presents standard MET values. The RMR reflects about 50 to 75% of one's daily energy expenditure, with variation by age, weight, height, sex, and lean body mass. kg -1.min -1 as a proxy value for the resting metabolic rate (RMR) of 1 MET. It should be noted that expressing the standard MET values relative to body weight is desirable because this normalizes the data and minimizes the variation between large and small individuals. As such, the standard MET is a shorthand way of expressing the mass-specific energy costs of activities 1. This resulting MET level is termed a “standard MET” value. kg -1.min -1) and dividing them by 3.5 ml. The MET levels in the 2011 Compendium are a direct translation of the mass-specific energy costs, computed by taking the energy costs (VO 2 ml. The term METs is used in the Compendium to reflect the energy costs of physical activities. Therefore it is of interest to supply a method that is acceptable for adjusting MET values to fit this additional application. However, the Compendium is frequently used outside of its original scope. The Compendium was not developed to determine the precise energy cost of activities within an individual. The Compendium of Physical Activities (Compendium) was developed in the late 1980s for use in epidemiologic and surveillance studies to standardize the MET intensities used in various physical activity questionnaires.
