1. What is the Kcal From Exercise Formula?

The Kcal From Exercise formula estimates energy expenditure during physical activity based on MET (Metabolic Equivalent of Task), weight, and exercise duration. It provides a practical way to calculate calories burned during various exercises.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ kcal = \frac{MET \times 3.5 \times Weight \times Time}{200} \]

Where:

\( MET \) — Metabolic Equivalent of Task (unitless)
\( Weight \) — Body weight (kg)
\( Time \) — Exercise duration (min)
\( kcal \) — Calories burned (kcal)

Explanation: The formula calculates energy expenditure by multiplying MET value (intensity of activity), weight, and time, then dividing by 200 to convert to kilocalories.

3. Importance of Kcal Calculation

Details: Accurate calorie expenditure estimation is crucial for weight management, exercise planning, and maintaining energy balance in fitness and health programs.

4. Using the Calculator

Tips: Enter MET value (consult MET tables for different activities), weight in kg, and exercise time in minutes. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is MET and how is it determined?
A: MET (Metabolic Equivalent of Task) is a unit that represents the energy cost of physical activities. 1 MET equals the energy expenditure at rest. Standard MET values are available for various activities.

Q2: How accurate is this calculation?
A: This provides a reasonable estimate for general purposes. Individual variations in metabolism, fitness level, and exercise efficiency can affect actual calorie burn.

Q3: Can this formula be used for all types of exercise?
A: Yes, as long as you have the correct MET value for the specific activity. Different activities have different MET values based on intensity.

Q4: Why divide by 200 in the formula?
A: The division by 200 converts the result to kilocalories, as 1 liter of oxygen consumption equals approximately 5 kcal, and the formula is derived from oxygen consumption calculations.

Q5: Should I use this for weight loss planning?
A: This can be a useful tool for estimating exercise calorie expenditure as part of a comprehensive weight management program, but individual results may vary.
