How We Calculate Calories Burned for Swimming in Seattle
Our calculator uses the standard MET (Metabolic Equivalent of Task) formula with a local climate adjustment for Seattle:
Calories = MET × Weight (kg) × Duration (hrs) × Climate Factor
= 7 × Weight (kg) × Duration (hrs) × 1.03
The MET value of 7 for swimming is sourced from the Compendium of Physical Activities. The climate factor of 1.03 accounts for Seattle's average temperature of 47°F. Research shows that exercising in non-neutral temperatures increases energy expenditure as the body works to maintain its core temperature.
Swimming at a moderate pace provides a full-body workout with virtually zero impact on joints. The water provides natural resistance in every direction, making swimming one of the most complete exercises available. It simultaneously builds cardiovascular endurance, muscular strength, and flexibility. Swimming is ideal for people with joint issues, arthritis, or injuries, and it is one of the few exercises that works nearly every major muscle group in a single session.
