1. What is the Walking MET Equation?

The Walking MET equation estimates the metabolic equivalent of task (MET) for walking based on speed and grade. MET represents the energy cost of physical activities as multiples of resting metabolic rate.

2. How Does the Calculator Work?

The calculator uses the Walking MET equation:

Where:

• \( Speed \) — Walking speed in meters per minute (m/min)
• \( Grade \) — Incline grade as a fraction (e.g., 0.1 for 10% grade)

Explanation: The equation accounts for both horizontal and vertical components of walking, with 3.5 representing resting metabolic rate.

3. Importance of MET Calculation

Details: MET values are crucial for estimating energy expenditure during physical activity, designing exercise programs, and comparing intensity of different activities.

4. Using the Calculator

Tips: Enter speed in m/min (1 mph ≈ 26.8224 m/min) and grade as a fraction (10% = 0.1). All values must be valid (speed > 0, grade between 0-1).

5. Frequently Asked Questions (FAQ)

Q1: What is a typical MET value for walking?
A: Normal walking (3-4 mph) typically ranges from 3-6 METs, depending on speed and incline.

Q2: How accurate is this equation?
A: It provides reasonable estimates for most walking conditions but may be less accurate for very slow or fast speeds.

Q3: Can I use this for running?
A: No, this equation is specifically for walking. Running has different energy costs and requires a different equation.

Q4: How do I convert mph to m/min?
A: Multiply mph by 26.8224 (1 mph = 26.8224 m/min).

Q5: What's the resting MET value?
A: 1 MET is defined as resting metabolic rate, approximately 3.5 ml O₂/kg/min.
