1. What is METs?

METs (Metabolic Equivalents) are a way to measure energy expenditure. One MET is defined as the energy cost of sitting quietly, equivalent to a VO₂ of 3.5 ml/kg/min.

2. How Does the Calculator Work?

The calculator uses the METs formula:

Where:

• \( VO_2 \) — Oxygen consumption (ml/kg/min)
• 3.5 — Baseline oxygen consumption at rest (1 MET)

Explanation: The equation converts oxygen consumption to multiples of the resting metabolic rate.

3. Importance of METs Calculation

Details: METs are widely used in exercise physiology to quantify exercise intensity, prescribe exercise programs, and assess functional capacity.

4. Using the Calculator

Tips: Enter VO₂ in ml/kg/min. The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What are typical METs values for activities?
A: Walking at 3 mph ≈ 3.5 METs, jogging ≈ 7 METs, competitive swimming ≈ 10 METs.

Q2: How are METs used clinically?
A: Used in cardiac rehabilitation, exercise stress testing, and to assess functional capacity.

Q3: What is the relationship between METs and calories?
A: Calories burned = METs × weight in kg × duration in hours.

Q4: What are METs thresholds for exercise intensity?
A: Light intensity <3 METs, moderate 3-6 METs, vigorous >6 METs.

Q5: Are there limitations to METs?
A: METs assume linear relationship between VO₂ and energy cost, which may vary between individuals.
