1. What is the Treadmill MET Equation?

The Treadmill MET equation estimates metabolic equivalents (METs) for walking or running on a treadmill based on speed and grade. METs represent the energy cost of physical activities as multiples of resting metabolic rate.

2. How Does the Calculator Work?

The calculator uses the Treadmill MET equation:

Where:

• \( Speed \) — Treadmill speed in kilometers per hour (km/h)
• \( Grade \) — Treadmill incline as percentage grade (%)

Explanation: The equation accounts for both the linear and quadratic effects of speed, plus the additional energy cost of incline.

3. Importance of MET Calculation

Details: MET values help quantify exercise intensity, estimate calorie expenditure, and guide exercise prescription in clinical and fitness settings.

4. Using the Calculator

Tips: Enter speed in km/h (typical walking: 3-6 km/h, running: >8 km/h) and grade in percentage (0% = flat, 10% = steep incline).

5. Frequently Asked Questions (FAQ)

Q1: What is a MET?
A: One MET is the energy expenditure at rest (~3.5 mL O₂/kg/min). Activities are rated in multiples of this baseline.

Q2: How accurate is this equation?
A: It provides reasonable estimates for most individuals walking/running on treadmills, though actual energy expenditure may vary by ±10-20%.

Q3: Does this work for all speeds?
A: Best for speeds between 1.9-12.1 km/h (walking to fast running). Less accurate for very slow or sprint speeds.

Q4: How does grade affect METs?
A: Each 1% grade increases energy cost by ~0.1 METs at walking speeds, with greater effects at higher speeds.

Q5: Can I calculate calories from METs?
A: Yes, calories/min ≈ METs × 3.5 × weight(kg) ÷ 200. Example: 5 METs for 70kg = ~6.1 kcal/min.
