What is metabolic equivalent?
Metabolic equivalents are defined as the caloric consumption of an active individual compared with the resting basal metabolic rate at rest. They are used during EST as an estimate of functional capacity.
What is the MET value?
Metabolic equivalent (MET) relates to the rate of the body’s oxygen uptake for a given activity as a multiple of resting VO2. On average, an individual utilises 3.5 mLof O 2 per kg of body weight per minute (ml.kg −1 .min −1 ). Therefore, one MET equals a VO 2 of 3.5 ml.kg −1 .min −1. MET value is assigned to an activity by measuring the VO 2 for that activity.
What are the METs for light intensity?
Light intensity activities are those activities with a MET value ranging from ≥1.5 to 2.99 METs , moderate intensity activities have a MET value ranging from 3 to 5.99 METs, and vigorous activities have a MET value ≥6 METs. Freedson et al. (1998) used these absolute MET values to generate activity count cut-points to classify activity intensity. Intensity thresholds using activity counts were derived using the equation mentioned previously. Table 2.1 presents Freedson activity count cut-points for the different categories of PA intensity.
What is the MET of oxygen?
The Metabolic Equivalent (MET) is the amount of oxygen required during rest calculated per mass of 1 kg body weight and time [ 33 ]. An average of 3.5 ml O 2 /kg/min has been determined as the oxygen consumption at the BMR; however, age, gender, and illness can have considerable effects on this value [ 40, 41 ]. Because this value is given per kilogram body weight, it is also called the Relative Oxygen Consumption (relative ). Multiplication with the bodyweight yields the Absolute Oxygen Consumption (absolute ). For example, a person weighing 80 kg would have an absolute of 280 ml/min at rest. However, the relative value is of greater interest, because it easily allows comparison of the values of different persons with different body weights by eliminating the influence of the aforementioned body weight. The MET has been introduced to allow for quantification of different amounts of oxygen consumption and also to reduce the necessity of calculating with the somewhat cumbersome value of 3.5. For example, a 10-fold increase of oxygen consumption (and thus energy expenditure) can either be expressed as 35 ml O 2 /kg/min or simply as 10 MET and so on.
What is MET on ETT?
This information is useful for the cardiac rehabilitation physiotherapist for prescribing intensity, as well as to identify the functional capacity of the patient. For example, a patient with a peak capacity of seven METs cannot be prescribed skipping (8–10 METs). An individual’s exercises can be prescribed and regulated by choice of activities according to the MET values for them (see Table 8.5 ). (Please also refer to functional capacity described later in the chapter.)
Is walking a MET?
Table 8.7 gives the minimal and maximal activity values. Walking is a complex activity which requires balance and use of arm and trunk movements, and, hence, there is variation in the MET value.
What is the metabolic equivalent of task?
The original definition of metabolic equivalent of task is the oxygen used by a person in milliliters per minute per kilogram body mass divided by 3.5. Other definitions which roughly produce the same numbers have been devised, such as:
What is MET in medical terms?
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.
What is a MET value?
Although the RMR of any person may deviate from the reference value, 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., 3 km/h) would require twice the energy that an average person consumes at rest (e.g., sitting quietly).

What is metabolic equivalent?
Metabolic equivalents are defined as caloric consumption (by means of breathing) of an active individual compared with their resting basal metabolic rate. It is based on how much oxygen the body consumes during activity compared to how much oxygen the body consumes at rest. Most individuals at rest utilize 3.5mL of oxygen per kg …
What is a METS?
METS are associated with planned, deliberate exercise where NEAT is the cost of energy involved in spontaneous activity . Remember, these equations only provide us with estimates of how many calories we expend during various activities.
What does it mean when something requires 2 METS?
If something requires 2 METS, then it requires twice the resting metabolism. When performing exercise, MET values are assigned to various forms of physical activity to determine how many calories are expended during that activity.
What is metabolic equivalent?
The metabolic equivalent for task (MET) is a unit that estimates the amount of energy used by the body during physical activity, as compared to resting metabolism. The unit is standardized so it can apply to people of varying body weight and compare different activities.
What is MET in exercise?
MET can be expressed in terms of oxygen use or kilocalories (what you commonly think of as calories). By using MET, you can compare the exertion required for different activities. At 2 MET you are using twice the calories per minute than you do at rest.
What Is a MET?
MET can be expressed in terms of oxygen use or kilocalories (what you commonly think of as calories). By using MET, you can compare the exertion required for different activities.
What does a MET of 4 mean?
So, an activity with a MET value of 4 means you’re exerting four times the energy than you would if you were sitting still.
What is MET in exercise?
A MET is a way to measure your body’s expenditure of energy. The higher the MET value of a particular activity, the more energy your muscles will need to expend to do that activity. Knowing the MET value of an activity can also be helpful in calculating how many calories you burn during exercise.
How to calculate calories burned per minute?
The formula to use is: METs x 3.5 x (your body weight in kilograms) / 200 = calories burned per minute. For example, say you weigh 160 pounds (approximately 73 kg) and you play singles tennis, which has a MET value of 8. The formula would work as follows: 8 x 3.5 x 73 / 200 = 10.2 calories per minute.
How to calculate METs?
What is a MET? 1 METs = metabolic equivalents. 2 One MET is defined as the energy you use when you’re resting or sitting still. 3 An activity that has a value of 4 METs means you’re exerting four times the energy than you would if you were sitting still.

How to calculate the energy cost of physical activity?
The energy cost of an activity can be determined by dividing the relative oxygen cost of the activity (ml O2/kg/min) x by 3.5. This article summarizes and presents energy expenditure values for numerous household and recreational activities in both METS and watts units. Also, the intensity levels (in METS) for selected exercise protocols are compared stage by stage. In spite of its limitations, the MET concept provides a convenient method to describe the functional capacity or exercise tolerance of an individual as determined from progressive exercise testing and to define a repertoire of physical activities in which a person may participate safely, without exceeding a prescribed intensity level.
What is a MET score of 1-4?
Activities with a MET score of 1-4 are in the low-intensity category. They would not improve the cardiovascular fitness of most people, though they could be a good starting point for some. Activities with a MET score of 5-8 are classified as moderate and would be appropriate for those who are older or sedentary. Activities with a MET score over 8 are high intensity and are best for improving fitness as long as they can be done safely.
How accurate are Met scores?
MET scores work well for comparing tasks. They are less accurate when they are used to estimate the number of calories actually burned by an individual during a task. A 40-year-old man who weighed 70 kilograms (about 154 pounds) was used in the original calculations. Obviously, most people don’t fit that age and weight profile.
Is a Met score of 10 good?
Those with MET scores below 5 may be risking health problems. Any score below 7 should trigger concern. A score of 10 is good. Some occupations, such as firefighting, are best performed by those with a MET score of 12 or higher.
Overview
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, set by convention at 3.5 mL of oxygen per kilogram per minute, which is roughly equivalent to the energy expended when sitting quietly.
Quantitative definitions
The original definition of metabolic equivalent of task is the oxygen used by a person in milliliters per minute per kilogram body mass divided by 3.5.
Other definitions which roughly produce the same numbers have been devised, such as:
where
• kcal = kilocalorie
Use
MET: 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 to 3.5 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…
Exercise guidelines
The American College of Sports Medicine and American Heart Association guidelines count periods of at least 10 minutes of moderate MET level activity towards their recommended daily amounts of exercise. For healthy adults aged 18 to 65, the guidelines recommend moderate exercise for 30 minutes five days a week, or vigorous aerobic exercise for 20 minutes three days a week.
Limitations
The definition of MET is problematic when used for specific persons. By convention, 1 MET is considered equivalent to the consumption of 3.5 ml O2·kg ·min (or 3.5 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 tre…
Standardized definition for research
The Compendium of Physical Activities was developed for use in epidemiologic studies to standardize the assignment of MET intensities in physical activity questionnaires. Dr. Bill Haskell from Stanford University conceptualized the compendium and developed a prototype for the document. The compendium was used first in the Survey of Activity, Fitness, and Exercise (SAFE study – 1987 to 1989) to code and score physical activity records. Since then, the compendium …
