What is the MET level of a person that is running on a level treadmill at 6 mph?

To determine the MET level of a person who is running on a level treadmill at 6 mph, we can look up the MET value for running and calculate it based on the speed.

The MET (Metabolic Equivalent of Task) is a unit used to estimate the amount of energy expended during physical activities compared to a person's resting metabolic rate. One MET is equal to the energy expenditure at rest.

According to the Compendium of Physical Activities, the MET value for running is 8.0 METs. This means that running at a speed of 6 mph is equivalent to 8 times the resting energy expenditure.

To calculate the MET level, divide the MET value of running (8.0 METs) by the resting metabolic rate (usually estimated as 3.5 mL of oxygen per kilogram of body weight per minute).

Let's assume a person weighs 68 kilograms (150 pounds). The calculation would be as follows:

MET level = MET value / resting metabolic rate
= 8.0 METs / 3.5 mL/kg/min

To convert mL/kg/min to METs, you can divide by 3.5 to obtain the following:

MET level = 8.0 METs / 3.5
= 2.29

Therefore, running on a level treadmill at 6 mph would have a MET level of approximately 2.29. This means that the person is expending energy at a rate approximately 2.29 times their resting metabolic rate.
