Overview

Calculate calories burned while swimming by stroke type (freestyle, backstroke, breaststroke, butterfly) and intensity. Uses MET-based formulas reflecting the energy expenditure characteristics of each stroke.

Formula

Calories Burned (kcal) = MET × Body Weight (kg) × Duration (hours)

Swimming MET Values by Stroke:
• Freestyle (moderate) = 5.8
• Freestyle (vigorous) = 9.8
• Backstroke = 4.8
• Breaststroke = 5.3
• Butterfly = 13.8
• Water Walking = 4.5
• Aqua Aerobics = 5.5

How to Use

1. 1Enter your body weight (e.g., 65 kg).
2. 2Select the swimming stroke (freestyle, backstroke, breaststroke, butterfly).
3. 3Select the intensity level (moderate / vigorous).
4. 4Enter the swimming duration in minutes.
5. 5Calories burned are calculated automatically.

Tips

• ✔Butterfly burns the most calories but is hard to sustain — alternate strokes for best results.
• ✔Swimming is a full-body, low-impact exercise that builds both strength and cardiovascular endurance.
• ✔Colder water temperatures (below 26°C) increase calorie burn as the body works to maintain core temperature.
• ✔Interval swimming (50 m sprint + 50 m easy) is highly effective for fitness improvement.
• ✔Appetite tends to increase after swimming — be mindful of post-swim dietary choices.
