One MET is the energy cost of standing quietly at rest and represents an oxygen uptake of how many milliliters per kilogram of body weight per minute?

The correct answer is 3.5 milliliters of oxygen per kilogram of body weight per minute. This value is fundamental in exercise physiology and is defined as one MET, which serves as a baseline measurement to assess energy expenditure. When a person is at rest, their body requires a specific amount of oxygen to maintain basic physiological functions, and this amount is represented by the constant 3.5 mL/kg/min.

This figure is widely accepted and used in various fitness assessments to evaluate the intensity of physical activities. For instance, activities can be expressed in multiples of METs, helping to quantify their demands on the body. Activities that require higher oxygen uptake will have higher MET values compared to rest.

Understanding this concept is essential for creating exercise programs, as it helps in determining the appropriate intensity for different fitness levels and understanding how training can affect aerobic capacity and overall health.
