When discussing physical fitness, what is the standard MET value representing energy expenditure at rest?

The standard MET (Metabolic Equivalent of Task) value representing energy expenditure at rest is defined as 1 MET = 3.5 ml/kg/min. This value indicates the amount of oxygen consumed at rest by an individual, which can be used as a baseline to estimate energy expenditure during various activities. The measurement is essential for understanding the intensity of physical activities in relation to resting metabolic rate. This 3.5 ml/kg/min value is crucial for various health and fitness assessments, providing a standard for both measuring exercise intensity and quantifying physical fitness levels. The other values listed do not correspond to the established standard for resting metabolic rate.
