Swimming is often regarded as a good all-round exercise, and indeed it is useful for some people because the support of the water reduces the impact on joints. But exercise on cold water may not be ideal if you’re trying to lose weight.
Researchers at the University of Florida asked subjects to exercise on a static bike underwater for 45 minutes, first in water at 20degrees C, then in water at 33 degrees C. They also spent 45 minutes just resting. After each session they spent an hour in a room full of food, without being told that their calorie intake would be monitored.
After exercising in cold water the subjects ate 44% more calories than after the warm-water exercise and 41% more than after just resting. It seems that body temperatures affects post-appetite, which may explain a previous study that found women who swam lost less weight than those who ran or cycled.
