Swimming and running are good exercise methods, which can help you lose weight. But the overall weight loss effect of swimming is not as good as that of running. From the point of view of energy consumption, in the case of the same intensity (heart rate), the calories consumed by the two are similar, and swimming is indeed slightly higher than running.

The heat consumed by swimming ranks among the best in all sports, because the resistance of water is 12 times that of air, and the heat transfer capacity of water is 25 times faster than that of air. In addition, swimming can also exercise the whole body muscles and enhance the cardiopulmonary function.

Running is a simple way of exercise, which can exercise heart and lung function, enhance physical fitness and reduce stress. But running has a great influence on the knees and needs protection.
