1. What is the Calorie Burning Equation?

The calorie burning equation estimates calories burned during physical activity using MET (Metabolic Equivalent of Task) values, which represent the energy cost of activities.

2. How Does the Calculator Work?

The calculator uses the calorie burning equation:

Where:

• \( MET \) — Metabolic Equivalent of Task (activity intensity)
• \( weight \) — Body weight in kilograms
• \( time \) — Duration of activity in hours

Explanation: The equation calculates energy expenditure based on activity intensity, body weight, and duration.

3. Importance of MET Values

Details: MET values standardize the measurement of energy expenditure across different activities. 1 MET equals the energy expended at rest (about 1 kcal/kg/hour).

4. Using the Calculator

Tips: Select your weight lifting intensity, enter your weight in kg, and the duration in hours. All values must be valid (weight > 0, time > 0).

5. Frequently Asked Questions (FAQ)

Q1: What are typical MET values for weight lifting?
A: Light effort: ~3.5 MET, moderate: ~5 MET, vigorous: ~6 MET, circuit training: ~8 MET.

Q2: How accurate is this calculation?
A: It provides a reasonable estimate but individual results may vary based on factors like body composition and exercise intensity.

Q3: Should I use kg or pounds?
A: The calculator uses kg. To convert pounds to kg: divide by 2.205.

Q4: Does this account for afterburn effect?
A: No, this calculates only calories burned during the activity. Weight lifting may increase metabolism for hours afterward.

Q5: Can I use this for other exercises?
A: Yes, but you would need to select the appropriate MET value for the specific activity.
