1. What is the Treadmill MET Equation?

The Treadmill MET equation estimates the metabolic equivalent (MET) of treadmill activity 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 Treadmill MET equation:

Where:

• \( Speed \) — Treadmill speed in meters per minute (m/min)
• \( Grade \) — Treadmill grade as a fraction (e.g., 0.05 for 5% grade)

Explanation: The equation accounts for both horizontal and vertical components of treadmill walking/running. The 3.5 represents resting metabolic rate, 0.1×Speed accounts for horizontal movement, and 1.8×Speed×Grade accounts for vertical movement.

3. Importance of MET Calculation

Details: MET values are crucial for quantifying exercise intensity, prescribing exercise programs, estimating energy expenditure, and comparing different physical activities.

4. Using the Calculator

Tips: Enter speed in m/min (convert from mph by multiplying by 26.8224) and grade as a fraction (e.g., 0.05 for 5% grade). Both values must be valid (speed > 0, grade between 0-1).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this MET estimation?
A: The equation provides a good estimate for most individuals, but actual MET values may vary based on individual factors like fitness level and body composition.

Q2: What are typical MET values for treadmill exercise?
A: Walking (2-4 METs), jogging (6-8 METs), running (8+ METs). Higher grades significantly increase MET values.

Q3: How do I convert mph to m/min?
A: Multiply mph by 26.8224 (1 mph = 26.8224 m/min).

Q4: Does this equation work for both walking and running?
A: Yes, it applies to both walking and running on a treadmill.

Q5: How can I use MET values to estimate calories burned?
A: Calories ≈ METs × weight in kg × duration in hours. For example, a 70kg person doing 5 MET activity for 0.5 hours burns about 175 calories.
