A MET is defined as how much oxygen consumption?

A MET, or Metabolic Equivalent of Task, is defined as the amount of oxygen consumed while sitting at rest. The standard value for this resting oxygen consumption is established at 3.5 ml of oxygen per kilogram of body weight per minute. This benchmark is valuable in understanding the energy expenditure for various physical activities compared to the resting state. Thus, when considering the definitions and standard measurements, 3.5 ml/kg/min as the value for one MET is widely accepted in exercise physiology and is used to quantify the intensity of various exercises relative to resting metabolic rate.
