1. What is the METs Calculation?

The METs (Metabolic Equivalents) calculation estimates energy expenditure during physical activities. One MET represents the energy cost of sitting quietly, equivalent to an oxygen consumption of 3.5 ml/kg/min.

2. How Does the Calculator Work?

The calculator uses the METs formula:

Where:

• \( VO2 \) — Oxygen Consumption (ml/kg/min)
• \( 3.5 \) — Baseline oxygen consumption at rest

Explanation: The equation converts oxygen consumption values to METs, providing a standardized measure of exercise intensity.

3. Importance of METs Calculation

Details: METs calculation is essential for assessing exercise intensity, prescribing appropriate physical activity levels, and comparing energy expenditure across different activities.

4. Using the Calculator

Tips: Enter oxygen consumption in ml/kg/min. The value must be valid (VO2 > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is a MET value?
A: A MET is a ratio of your working metabolic rate relative to your resting metabolic rate. One MET is defined as the energy it takes to sit quietly.

Q2: What are typical MET values for different activities?
A: Light activities: 1.1-2.9 METs, Moderate activities: 3.0-5.9 METs, Vigorous activities: ≥6.0 METs.

Q3: How is VO2 measured?
A: VO2 can be measured directly through gas analysis during exercise testing or estimated using various equations and formulas.

Q4: Are there limitations to METs calculations?
A: METs provide estimates and may vary based on individual factors such as age, fitness level, and body composition.

Q5: How are METs used in clinical practice?
A: METs are used to prescribe exercise intensity, assess functional capacity, and guide cardiac rehabilitation programs.
