1. What is the Calorie Burn Equation?

The calorie burn equation estimates energy expenditure during physical activity based on MET (Metabolic Equivalent of Task) values, duration of activity, and body weight. It provides a standardized way to compare energy expenditure across different activities.

2. How Does the Calculator Work?

The calculator uses the calorie burn equation:

Where:

• \( Time \) — Duration of activity in hours
• \( MET \) — Metabolic Equivalent of Task value
• \( Weight \) — Body weight in kilograms

Explanation: The equation accounts for the intensity of activity (MET), duration, and body weight to estimate total energy expenditure.

3. Importance of MET Values

Details: MET values represent the ratio of working metabolic rate to resting metabolic rate. One MET is defined as 1 kcal/kg/hour and is roughly equivalent to the energy cost of sitting quietly.

4. Using the Calculator

Tips: Enter time in hours (e.g., 0.5 for 30 minutes), select appropriate MET value for your activity, and enter your weight in kg. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical MET values for elliptical vs running?
A: Elliptical training typically ranges from 5-8 METs, while running at 6 mph is about 10 METs, and at 10 mph about 16 METs.

Q2: How accurate is this calculation?
A: It provides a reasonable estimate for most people, but individual variations in metabolism can affect actual calorie burn.

Q3: Why use kg for weight?
A: The equation is designed using metric measurements. To convert pounds to kg, divide by 2.205.

Q4: Does this account for afterburn effect?
A: No, this calculation only estimates calories burned during the activity itself.

Q5: How does elliptical compare to running for calorie burn?
A: Running typically burns more calories per minute due to higher MET values, but elliptical training is lower impact and may be sustainable for longer durations.
