1. What is the MET Level for Walking?

The MET (Metabolic Equivalent of Task) is a unit that estimates the energy cost of physical activities. For walking on a treadmill, the MET level depends on both speed and incline grade.

2. How Does the Calculator Work?

The calculator uses the walking MET equation:

Where:

• \( Speed \) — Walking speed in miles per hour (mph)
• \( Grade \) — Treadmill incline grade as percentage

Explanation: The equation accounts for both the base metabolic cost of walking and the additional energy expenditure from increased speed and incline.

3. Importance of MET Calculation

Details: Knowing the MET level helps in exercise prescription, energy expenditure estimation, and comparing intensity of different activities.

4. Using the Calculator

Tips: Enter walking speed in mph and grade as percentage (e.g., 5 for 5% grade). All values must be valid (speed > 0, grade ≥ 0).

5. Frequently Asked Questions (FAQ)

Q1: What is a typical MET range for walking?
A: Normal walking typically ranges from 2-6 METs depending on speed and incline.

Q2: How accurate is this equation?
A: It provides a good estimate for most people walking on treadmills, but individual variations exist.

Q3: Does this apply to running?
A: No, this equation is specifically for walking. Running has a different MET calculation.

Q4: How can I use MET values?
A: METs can help estimate calories burned (METs × weight in kg × time in hours).

Q5: What about walking outdoors?
A: This equation is for treadmill walking where grade is precisely known. Outdoor walking may vary.
