metabolic equivalent
Also written as: MET — Metabolic Equivalent
Unit of measurement expressing the energy cost of physical activities as multiples of resting metabolic rate.
Full Definition
A standardized unit that quantifies the intensity of physical activities, where 1 MET equals the energy expenditure at rest (approximately 3.5 mL O₂/kg/min). Metabolic equivalents provide a common language for exercise prescription, allowing clinicians to prescribe specific activity intensities and track functional improvements. Understanding MET values helps cardiac rehabilitation professionals communicate exercise recommendations and assess patient progress objectively.
Usage
Usage note: Often used in plural form (METs); distinguish from other measures of oxygen consumption.
In Context
- "The patient achieved 8 metabolic equivalents during the exercise stress test." — Test report
- "Household activities typically range from 2-4 metabolic equivalents depending on intensity." — Patient education material
