What are these acronyms of the treadmill?

Question

METS and WATTS what do they mean?

Sorry not "of" I meant "on".

Answer 1

Both watts and METs are measures of power, that is, how quickly you are doing work, or burning calories. Watts (as in watts of a light bulb) is directly related to calories/energy used per hour. METs (metabolic equivalents) also measure energy per hour but take into account body weight.
With similar fitness, a bigger person could use more energy giving higher watts, but small and big people of equal fitness should do about the same number of METs.
Depending on the equipment, these measure should not necessarily be taken too literally. For instance, you cannot get METs without entering your body weight. Some machines might just assume an "average" body weight if you don't input it. Similarly, watts are hard to measure on a treadmill with external power. A heavier person generates more watts at the same speed than a lighter person, but a treadmill might not be able to measure this as well as, say, an exercise bike where all power is supplied directly by the person.

METs are "metabolic equivalents".
From http://www.hsph.harvard.edu/nutritionsource/Exercise.htm "One MET is defined as the energy it takes to sit quietly. For the average adult, this is about one calorie per every 2.2 pounds of body weight per hour someone who weighs 160 pounds would burn approximately 70 calories an hour while sitting or sleeping.

Moderate intensity activities are those that get you moving fast enough or strenuously enough to burn off three to six times as much energy per minute as you do when you are sitting quietly, or exercises that clock in at 3-6 METs."

Answer 2

Treadmill Mets

Answer 3

Mets and WATTS provide an estimate of energy expenditure and intensity.

Use target heart rates instead.
