1. What is the METs Equation?

The METs (Metabolic Equivalent of Task) equation converts VO2 max (maximum oxygen consumption) to a standardized measure of energy expenditure. One MET is defined as the energy cost of sitting quietly.

2. How Does the Calculator Work?

The calculator uses the METs equation:

Where:

• \( VO2_{max} \) — Maximum oxygen consumption (mL/kg/min)
• 3.5 — Oxygen consumption at rest (mL/kg/min)

Explanation: The equation shows how many times greater the energy expenditure is compared to resting state.

3. Importance of METs Calculation

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

4. Using the Calculator

Tips: Enter VO2 max in mL/kg/min. The value must be positive. Typical values range from 20-80 mL/kg/min for most individuals.

5. Frequently Asked Questions (FAQ)

Q1: What is a good METs value?
A: 1 MET is resting. 3-6 METs is moderate activity. Above 6 METs is vigorous activity. Elite athletes may reach 20+ METs.

Q2: How is VO2 max measured?
A: Typically measured during maximal exercise testing with gas analysis, but can be estimated from submaximal tests.

Q3: What affects METs values?
A: Body composition, fitness level, age, and genetics all influence METs capacity.

Q4: Are there limitations to this calculation?
A: The 3.5 mL/kg/min standard assumes average resting metabolism - actual resting values vary slightly between individuals.

Q5: How are METs used clinically?
A: Used to prescribe exercise intensity, assess functional capacity in cardiac patients, and evaluate disability.
