Which of the following is NOT a category of MET values?

• A. Light MET
• B. Moderate MET
• C. Heavy MET
• D. Vigorous MET

Answer: (C)

MET, or Metabolic Equivalent of Task, is a value used to estimate the amount of energy expenditure for various physical activities. The classification of MET values generally includes certain standard categories to help measure the intensity of different exercises.

Light MET refers to activities that require minimal effort and do not significantly increase heart rate or breathing, such as standing or light household tasks. Moderate MET includes activities that involve a moderate level of effort, like brisk walking or gardening, which elevate heart rate but are still manageable for the average person. Vigorous MET consists of high-intensity activities that significantly increase heart rate and breathing, such as running or heavy cycling.

The term "Heavy MET" is not commonly recognized in the classification of MET values within exercise science or physical activity guidelines. Therefore, its absence from the official categories makes it the correct choice for the question, as it is not an established term used to categorize MET values. Understanding the recognized categories helps in accurately assessing exercise intensity and planning fitness routines effectively.
