Calculadora de Calorias Queimadas na Natação — Formula
## How Swimming Calorie Burn Is Calculated
### Formula
**Calories = MET x Weight (kg) x Duration (hours)**
MET (Metabolic Equivalent of Task) values for swimming vary by stroke and intensity.
### MET Values by Stroke
| Stroke | Light | Moderate | Vigorous |
|--------|-------|----------|----------|
| Freestyle | 5.0 | 7.0 | 10.0 |
| Backstroke | 4.0 | 6.0 | 8.0 |
| Breaststroke | 5.0 | 7.0 | 10.0 |
| Butterfly | - | - | 11.0 |
### Why Swimming Burns So Many Calories
Swimming engages the entire body, provides resistance in every direction, and requires energy for thermoregulation in cool water.

Exemplo Resolvido
A 160 lb person swims freestyle at moderate effort for 30 minutes.
- Weight in kg = 160 x 0.4536 = 72.6 kg.
- Duration in hours = 30 / 60 = 0.5 hours.
- Calories = 7 x 72.6 x 0.5 = 254 kcal.
- Rate = 254 / 30 = 8.5 kcal/min.
