1. What is the Calorie Burn Formula?

The calorie burn formula estimates calories burned during physical activity based on duration, intensity (MET value), and body weight. It's particularly useful for tracking energy expenditure during swimming classes.

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 (intensity level)
• \( Weight \) — Body weight in kilograms

Explanation: The formula accounts for how long, how intense, and how much you weigh to estimate energy expenditure.

3. Importance of Calorie Calculation

Details: Understanding calorie burn helps with weight management, exercise planning, and achieving fitness goals. It's especially useful for swimmers to track their energy expenditure.

4. Using the Calculator

Tips: Enter time in hours (e.g., 1.5 for 1 hour 30 minutes), the appropriate MET value for your swimming intensity, and your weight in kg. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical MET values for swimming?
A: Light swimming ≈ 5-6 METs, moderate ≈ 7-8 METs, vigorous ≈ 9-10 METs. Competitive swimming can be 10+ METs.

Q2: How accurate is this calculation?
A: It provides a reasonable estimate but individual factors like swimming efficiency and body composition affect actual burn.

Q3: Should I use my current weight or goal weight?
A: Always use your current weight for accurate calculations.

Q4: Does stroke type affect calorie burn?
A: Yes, butterfly typically burns most, followed by freestyle, backstroke, then breaststroke.

Q5: How can I get more accurate results?
A: Consider using a heart rate monitor or fitness tracker specifically designed for swimming.
