how many kilocalories do you burn swimming for an hour versus walking?

Swimming burns more calories than walking. For example, a 150-pound person can burn around 400-500 kilocalories per hour swimming at a moderate pace, while walking at a moderate pace typically burns about 100 kilocalories per mile, which translates to approximately 300 kilocalories per hour when walking briskly^[2][4].

Swimming's efficiency comes from being a full-body workout, which requires more effort due to the resistance of the water^[4]. In contrast, walking is less intensive and easier on the joints, making both exercises beneficial depending on personal fitness goals and preferences^[1][3].
