1. What is the METs Score?

The METs (Metabolic Equivalents) score estimates the energy cost of physical activities. It's commonly used in exercise physiology and cardiology to assess functional capacity.

2. How Does the Calculator Work?

The calculator uses the METs equation:

Where:

• \( T \) — Time in minutes

Explanation: The equation calculates metabolic equivalents based on exercise duration, with the cubic term accounting for non-linear relationships.

3. Importance of METs Calculation

Details: METs scores are crucial for assessing exercise capacity, determining cardiac risk, and prescribing appropriate exercise regimens.

4. Using the Calculator

Tips: Enter exercise time in minutes. The value must be positive and typically ranges from 1 to 20 minutes for most clinical applications.

5. Frequently Asked Questions (FAQ)

Q1: What is a good METs score?
A: Generally, >10 METs indicates excellent capacity, 7-10 good, 4-7 moderate, and <4 poor functional capacity.

Q2: How is this different from exercise stress test METs?
A: This is a calculated estimate, while stress tests measure actual achieved METs during graded exercise.

Q3: What activities correspond to specific METs values?
A: 1 MET is resting. 3-6 METs is moderate activity like walking, while >9 METs is vigorous like running.

Q4: Are there limitations to this equation?
A: Accuracy may vary with individual fitness levels, body composition, and specific exercise modalities.

Q5: Should this replace clinical exercise testing?
A: No, this provides an estimate only. Actual exercise testing with monitoring is needed for precise assessment.
