1. What is a MET Score?

The MET (Metabolic Equivalent of Task) score quantifies the amount of energy expended during physical activity. One MET is defined as the energy cost of sitting quietly, equivalent to 3.5 ml of oxygen uptake per kg per minute.

2. How Does the Calculator Work?

The calculator uses the MET score formula:

Where:

• \( MET \) — Metabolic Equivalent of Task (dimensionless)
• \( time_{min} \) — Duration of activity in minutes

Explanation: The equation calculates the total energy expenditure by multiplying the MET value of an activity by the duration in minutes, then converting to hours by dividing by 60.

3. Importance of MET Score Calculation

Details: MET scores help quantify physical activity levels, guide exercise prescriptions, and assess energy expenditure for weight management.

4. Using the Calculator

Tips: Enter the MET value of your activity (common values range from 1 for sitting to 8+ for vigorous exercise) and the duration in minutes. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical MET values for common activities?
A: Walking (3-5 METs), jogging (7-8 METs), swimming (5-10 METs), cycling (4-12 METs depending on intensity).

Q2: How can I use MET scores for weight management?
A: Multiply your weight in kg by the MET score to estimate calories burned (kcal/kg/hour).

Q3: Are MET values the same for everyone?
A: While standardized, actual energy expenditure may vary based on fitness level, body composition, and efficiency of movement.

Q4: How accurate are MET scores?
A: They provide estimates. For precise measurements, direct calorimetry or portable metabolic analyzers are needed.

Q5: What's a good weekly MET score goal?
A: Health guidelines often recommend accumulating 500-1000 MET-minutes per week for health benefits.
