A MET (the resting level of O₂ consumption for humans)
A MET stands for "Metabolic Equivalent" and is considered the VO₂ required for one kilogram of living tissue at rest to survive. This has been determined to be 3.5 mL · kg^-1·min^-1.

From the above resting standard, we can classify various levels of exertion by a equivalent number of METs. The greater the level of exertion above rest, the greater the number of METs an activity will be.

For Example:
12 min per mile=8.7 METs
6 min per mile=16.3 METs
Archery=3 to 4 METs

By knowing the MET value, many other quantities and or values can be calculated (e.g., VO2 at rest, approximate VO2 for a given activity, number of calories used for a given activity, etc.)

What is your approximate Absolute VO₂ requirements at Rest? Your kcals at rest?
To figure your VO₂ at rest do the following:

• Convert your body weight by dividing your pounds by the conversion factor for kilograms (2.2)
• Multiple your kg weight (weight in kg) by the value of a MET (3.5 ml · kg-1·min-1). The result is an approximate value of your Absolute VO₂ in (mL) O₂ at rest.
  

How would you figure your approximate Resting Level kcal requirement if you know that 200 mL O₂ releases approximately 1 kcal energy?

Can you figure weight lost at resting level if you know that 3500 kcal is equivalent to one pound of weight (assume fat weight)?
