What is the metabolic equivalent?
The metabolic equivalent of the task, known as the Met or the metabolic equivalent, is a concept often used to indicate the amount of oxygen or energy that the body uses during physical activity. The unit of the metabolic equivalent expresses the ratio of the metabolic velocity of the average person, while performing a certain task compared to their metabolic speed at rest. In practical application, Met is a way to compare the level of exertion and energy spent when people of different weights do the same physical activity. The metabolic equivalent can also compare the aerobic intensity and energy expenditure on one person by one person.
usually agrees that 1 Met is the equivalent of energy or oxygen that uses the body at rest. One base is considered to be a resting metabolic speed or metabolic speed at which the body consumes 3.5 milliliters of oxygen per kilogram of body weight per minute. From a mathematical point of view 1 met = 50 kcal/hour/m2 surface surface of the body.
The heavier the body works during any activity, the more oxygen is consumed and the higher the level. Activity between 3 and 6 Mets is considered a slight intensity, such as a walk with a dog. The person experiences an increase in breathing and heart rate and burns 3.5 to 7 calories in a minute. Intensive activity, 6 Mets or higher, burns more than 7 calories per minute and includes running and playing basketball.
The MET concept can be used to issue fitness recommendations, to plan or monitor physical activity or measure aerobic intensity levels. For example, it is recommended that people get 500 to 1,000 met-minutes per week for good health. This is the equivalent of at least 150 minutes of moderate intensity or 90 minutes of intensive activity per week. The concept of the metabolic equivalent is also useful for prescribing exercises, such as the actual activity needed for the rehabilitation of patients with different conditions.
MetsEstimated predictions are based on controlled experiments and are highly inaccurate when they are applied to specific individuals. During physical activity, the actual energy expenditure, often described as "burned calories", depends on the body's body, the level of fitness and many other circumstances. Published metabolic equivalent values and "calorie calculators" based on METS are only averages and should not be used by individuals. Measurement of the actual METS usually includes a test belt test where a person wears a mask that measures oxygen consumption and carbon dioxide exhalation.
