In the context of exercise intensity, what do the MET values represent?

• A. The metabolic equivalent of task
• B. The minimum exercise duration
• C. The maximum heart rate
• D. The total calorie expenditure

Answer: (A)

The correct answer is that the MET values represent the metabolic equivalent of task. MET is a unit used to estimate the amount of oxygen used by the body during physical activity, which helps in comparing the intensity of different types of exercises. One MET is equivalent to the rate of energy expenditure while at rest; thus, higher MET values indicate a more intense level of physical activity.

For example, activities that have MET values of 5 or higher are considered moderate to vigorous exercises, which can significantly improve cardiovascular health and contribute to overall fitness. Understanding MET values is essential for designing exercise programs and assessing one’s exercise intensity and overall energy expenditure.
