1. What Is The Calories Burned Equation?

The calories burned equation estimates the number of calories expended during physical activity based on duration, metabolic equivalent (MET) value, and body weight. It provides a scientific approach to quantifying energy expenditure during various workouts and activities.

2. How Does The Calculator Work?

The calculator uses the calories burned equation:

Where:

• \( Duration \) — Exercise duration in minutes
• \( MET \) — Metabolic Equivalent of Task value
• \( Weight \) — Body weight in kilograms
• \( 3.5 \) — Oxygen consumption constant (mL/kg/min)
• \( 200 \) — Conversion factor to calories

Explanation: The equation calculates energy expenditure by multiplying duration by MET value (intensity), then by basal metabolic rate equivalent, and finally converting to calories.

3. Importance Of Calories Burned Calculation

Details: Accurate calorie expenditure estimation is crucial for weight management, fitness planning, nutritional guidance, and monitoring exercise effectiveness for health and performance goals.

4. Using The Calculator

Tips: Enter duration in minutes, MET value (3-12 for most activities), and weight in kilograms. All values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What Are MET Values And How Are They Determined?
A: MET (Metabolic Equivalent of Task) values represent exercise intensity relative to resting metabolism. 1 MET equals resting energy expenditure. Values are scientifically determined for various activities.

Q2: How Accurate Is This Calculation Method?
A: This provides a reasonable estimate for general purposes. Individual variations in metabolism, fitness level, and exercise efficiency can affect actual calorie burn by 10-20%.

Q3: What Are Common MET Values For Different Activities?
A: Walking (3-5 MET), running (8-12 MET), cycling (6-10 MET), swimming (6-8 MET), weight training (3-6 MET). Intensity affects MET values significantly.

Q4: Should I Include Warm-up And Cool-down Periods?
A: Yes, include all active exercise time. Warm-up and cool-down typically have lower MET values but still contribute to total calorie expenditure.

Q5: How Does Weight Affect Calories Burned?
A: Heavier individuals burn more calories doing the same activity because they're moving more mass. The calculation automatically accounts for this through the weight variable.
