In this case, even if the met value indicated is a better statistical prediction than published tables, there is no way to account for the person's actual rmr and thus energy expenditure (e.g., Kcal). In short, a person can use the met concept to plan or monitor physical activity levels or get an indication of the aerobic intensity and order of magnitude of energy expenditure for a specific activity, but not use the met concept to calculate actual energy. More specifically, from a strictly scientific point of view, statistically estimated predictions, such as met or bmi, are inaccurate when used for specific persons, and met values must be treated as indicative only, taking into account that both rmr and actual energy consumption are highly. Moreover, even the definition of met is problematic when used for specific persons. 4 5 by convention, 1 met is considered equivalent to the consumption.5 ml O2kg1min1 (or.5 ml of oxygen per kilogram of body mass per minute) and is roughly equivalent to the expenditure of 1 kcal per kilogram of body weight per hour. This value was first experimentally derived from the resting oxygen consumption of a particular subject (a healthy 40-year-old, 70 kg man) and must therefore be treated as a convention. Since the rmr of a person depends mainly on lean body mass (and not total weight) and other physiological factors such as health status, age, etc., actual rmr (and thus 1-met energy equivalents) may vary significantly from the kcal kgh) rule of thumb.
8 9 a met is the ratio of the rate of energy expended during an activity to the rate of energy expended at rest. For example, 1 met is the rate of energy expenditure while at rest. A 4 met activity expends 4 times the energy used by the body at rest. If a person does a 4 met activity for 30 minutes, he or she has done 4 x 30 120 met-minutes (or.0 met-hours) of physical activity. A person could also achieve 120 met-minutes by doing an 8 met activity for 15 minutes. 10 Physical activity met light intensity activities 3 sleeping.9 watching television.0 writing, desk work, typing.5 walking,.7 mph (2.7 km/h level ground, strolling, very slow.3 walking,.5 mph (4 km/h).9 Moderate intensity activities 3 to 6 bicycling, stationary, 50 watts, very light effort.0. Pushups, situps, pullups, jumping jacks heavy, vigorous effort.0 running jogging, in place.0 infectie rope jumping.0 Limitations in the usage of met to calculate actual energy expenditure edit published met values (or exercise calorie calculators on web sites, which are based on such values). The level of intensity at which a specific person performs a specific physical activity (e.g., the pace of walking, the speed of running, etc.) will deviate from the representative experimental conditions used for the calculation of the standard met values. Moreover, as is explained in the following, the actual energy expenditure and the rmr will differ according to the person's overall fitness level and other factors. The same holds for met (or kcal) values indicated in modern fitness exercise equipment, which are based on statistical models and are of indicative value only.

The compendium was used first in the. Survey of Activity, fitness, and Exercise (safe study - 1987 to onder 1989) to code and score physical activity records. Since then, the compendium has been used in studies worldwide to assign intensity units to physical activity questionnaires and to develop innovative ways to assess energy expenditure in physical activity studies. The compendium was published in 1993 and updated in 206 7, scope of usage of the met concept edit, epidemiology and public health edit, mET (Metabolic Equivalent The ratio of the work metabolic rate to the resting metabolic rate. One met is defined as 1 kcal/kg/hour and is roughly equivalent to the energy cost of sitting quietly. A met also is defined as oxygen uptake in ml/kg/min with one met equal to the oxygen cost of sitting quietly, equivalent.5 ml/kg/min. The met concept was primarily designed to be used in epidemiological surveys, where survey respondents answer the amount of time they spend for specific physical activities. 3 Moreover, met is used to provide general medical thresholds and guidelines to a population.

Actual energy expenditure (e.g., in calories or joules) during an activity depends on the person's body mass; therefore, the energy cost of the same activity will be different for persons of different weight. However, since the rmr is also dependent on body mass in a similar way, it is assumed that the ratio of this energy cost to the rmr of each person will remain more or less stable for the specific activity and thus independent of each. Citation needed, the 1 met reference value of 1 kcalkg1h1, is used by convention and refers to a typical metabolism at rest of an "average" individual. It is not an approximation. Basal Metabolic Rate (bmr which is the minimum metabolic rate obtained under specified conditions. This is illustrated by sleeping having a met.9, while an individual's normal sleeping metabolism may be greater than the bmr. Contents, compendium of Physical Activities edit, the, compendium of Physical Activities was developed for use in epidemiologic studies to standardize the assignment of met intensities in physical activity questionnaires. Bill Haskell from Stanford University conceptualized the compendium and developed a prototype for the document.
is defined as the ratio of metabolic rate (and therefore the rate of energy consumption) during a specific physical activity to a reference. Still another definition of 1 met.2 W/m2 (18.4 Btu/hft2 which is equal to the rate of energy produced per unit surface area of an average person seated at rest. The surface area of an average person.8 m2 (19 ft2). Metabolic rate is usually expressed in terms of unit area of the total body surface (ansi/ashrae standard 55 1 ). Originally, 1 met was considered as the. Resting Metabolic Rate (RMR) obtained during quiet sitting. 2 3, met values of activities range from.9 (sleeping) to 23 (running.5 km/h or a 4:17 mile pace). Although the rmr of any person may deviate from the reference value, 4 5, mET can be thought of as an index of the intensity of activities: for example, an activity with a met value of 2, such as walking at a slow pace (e.g. Met is used as a means of expressing the intensity and energy expenditure of activities in a way comparable among persons of different weight.
