What does METS mean in PHYSIOLOGY
METs stands for Metabolic Equivalents, and is a unit of measure which evaluates the amount of energy expended during physical activity. METs indicate the intensity level of an activity when compared to simply sitting at rest. Increasing the intensity level of any physical activity will mean a higher MET value, while activities that are lower in intensity will result in a decrease in MET values. Knowing how to calculate and understand MET levels can help individuals to better track their fitness activities and to construct more effective exercise programs.

What Does METs Mean?
A MET is simply one metabolic equivalent (MET), which is defined as the amount of oxygen consumed while sitting quietly at rest. Therefore, one MET equals an oxygen consumption of 3.5 milliliters per kilogram body weight per minute (3.5 ml/kg/min). This means that if you weigh 100 kg and are sitting quietly, your body would be consuming 350 ml of oxygen in one minute - this would be equal to one MET. In terms of physical activities, the number of METs indicates how much energy is being used during an activity compared to sitting at rest. Activities with higher intensity levels will require more energy than those which are less intensive, meaning that it requires more oxygen uptake (and therefore more calories burned) for these activities than it does for low-intensity activities such as walking or light stretching. As such, activities with higher intensity can be associated with higher numbers of METs than those with lower intensities such as jogging or swimming.
How To Calculate Your Own Personalized Target Number Of Metabolic Equivalents
Calculating your own personalized target number of metabolic equivalents requires some basic knowledge about how different workout intensities affect metabolic rate and subsequently Oxygen uptake. Generally speaking, high-intensity exercises such as running or sprinting will require more energy (measured by metabolic rate) compared to low-intensity exercises like walking or stretching - thus requiring you to consume more oxygen for the same duration and intensity of exercise. In order to get an accurate calculation for your own personalized target number of Metabolic Equivalents (METS), you must first consider your current weight along with the type and intensity level of exercise you plan on doing a given session - then multiply that by 3.5 (the baseline MET). For example, if a person weighing 150 pounds was performing jogging at 5 mph for 30 minutes they would have calculated their target number by multiplying their weight x.10 x 3.5 = 5 METS.
Essential Questions and Answers on METabolic equivalentS in "MEDICAL»PHYSIOLOGY"
What is a MET?
A MET or Metabolic Equivalent is a measure of the energy cost of physical activity, commonly used to quantify the energy expenditure associated with performing a particular task. It is typically expressed as an equivalent value for the amount of oxygen consumed while performing a specific activity, with one MET representing 3.5 milliliters of oxygen per kilogram of body weight per minute (3.5 mL/kg/min).
Where can I find information on METs?
The American College of Sports Medicine has a comprehensive set of information on different activities and their associated MET values which can be found at www.acsm.org. Additionally, numerous websites such as MayoClinic provide useful information regarding METs and their relevancy to physical activity.
How are METs calculated?
The calculation of a MET value is based on the amount of oxygen consumed in proportion to an individual's body weight while completing a given task or exercise. This calculation is based on constant factors such as age, gender, body composition and fitness level.
What does 1MET mean in terms of energy expended?
One metabolic equivalent (1MET) represents an expenditure rate of approximately 1 kcal/kg/hour during rest or light activity and 4-12 kcal/kg/hour during strenuous exercise for an average adult man weighing 70 kg (154 lbs).
Are higher intensity activities better for calorie burning?
Generally speaking, yes; however, it depends on individual fitness levels and goals as lower intensity activities may still be beneficial for someone who is trying to lose weight or increase cardiovascular endurance depending upon their current fitness level and goals. Therefore it is important to choose exercises that are appropriate for your current fitness level rather than pushing yourself too hard too quickly when it comes to calorie burning with physical activity.
How do I calculate calories burned during exercise using METs?
To calculate calories burned during exercise using Metabolic equivalents (METS), you will need to know your resting metabolic rate (RMR), which can be determined by measuring your breathing over several minutes while at rest or estimating from online calculators such as MyFitnessPal or Nutristrategy’s RMR calculator. Once you have your RMR measurement you can calculate the total calories burnt during any physical activity by multiplying the duration x your RMR x number of metabolic equivalents(METs). For example, if you have an RMR of 2000 kcal/day and run for 30 minutes at 9 mets you would burn ((30 minutes x 2000 kcal/day) x 9 mets) = 540 kcal in 30 mins.
Are there different types of METs?
Yes; there are aerobic metabolic equivalents (AMET) and non-aerobic metabolic equivalents (NMET). AMET are usually used to calculate the energy expenditure associated with aerobic activities such as walking, running and swimming whereas NMET are generally used to calculate the cost associated with resistance training activities such as weightlifting.
What are some examples of high intensity exercises with high MET values?
Examples include running at 8 mph (17 mets), HIIT cycling intervals (20 mets), Jumping rope(9mets), burpees(10mets) and stair climbing(15mets).
Does increasing my effort during an activity increase its corresponding MET value?
Yes; increasing effort increases the total energy expenditure associated with any given task thus increasing its corresponding met value.
Final Words:
Metabolic Equivalents (or “METs”) measure the amount of energy expended during physical activity when compared to sitting still at rest. A single MET is defined as the amount of oxygen consumed while resting; this means that increasing levels of physical activity require increasing amounts energy (expressed here as Total Oxygen Uptake) compared to resting - resulting in increased numbers on the Metabolic Equivalent scale accordingly.. Knowing how calculate and interpret these objective values can help us better track our individual fitness progress over time and ensure our efforts are correctly directed towards reaching our health goals safely and efficiently!
