What does the Metabolic Equivalent (MET) measure?

The Metabolic Equivalent (MET) is a unit that quantifies the energy expenditure of physical activities, providing a standardized measure for comparing the intensity of different exercises. One MET is defined as the rate of energy expenditure while at rest, typically calculated as 3.5 mL of oxygen per kg of body weight per minute.

By using METs, individuals can assess how various activities compare in terms of their energy costs. For instance, an activity that requires 5 METs means it demands five times the energy expended at rest. This measure is particularly useful for determining how much energy an activity will require based on a person's body weight and can assist in developing effective exercise programs tailored to specific fitness levels and health goals.

This understanding of METs is critical for fitness professionals as they design training regimens and recommend activities based on clients' energy expenditure and fitness objectives.
