Why Swimming Burns So Many Calories

Swimming engages the entire body, provides resistance in every direction, and requires energy for thermoregulation in cool water.

计算示例

A 160 lb person swims freestyle at moderate effort for 30 minutes.

  1. Weight in kg = 160 x 0.4536 = 72.6 kg.
  2. Duration in hours = 30 / 60 = 0.5 hours.
  3. Calories = 7 x 72.6 x 0.5 = 254 kcal.
  4. Rate = 254 / 30 = 8.5 kcal/min.
