John's Tips: Swim to get slim?
Monday, Nov 1, 2010
Swimming can burn a lot of calories, depending on the stroke and the intensity. So why does swimming usually result in less weight loss than comparable amounts of other aerobic activities, like running, cycling, and even walking. Scientists speculate that cold water dissipates much more heat from the body than air does, and that this energy loss may stimulate appetite to keep the body warm. A recent study at the University of Florida found that men who exercised in cold water ate about 300 more calories in the hour after their workout than men who exercised in warm water. Regular exposure to cold water may also encourage the body to maintain or increase fat stores under the skin to serve as insulation. The message from this is to come to the Y to swim in our nice warm pools.
