Compared with other number of sports, the swimming both fitness and fun, and unlike some sports so hard, so many people who wanted to lose weight through exercise of the people chose to swim. But often hear people complain every day to swim quite a long time can be weight loss, poor, and some even more by the more fat.
Shandong Institute of Physical Education, Professor Huang Dapeng said, speaking from the consumption of human body heat, swimming is undoubtedly a very good campaign. Because of water on heat conduction speed is 26 times the air, that is, at the same temperature, heat in the water consumption is on the ground 20 times, but why do some swimming, weight loss, poor?
Prof Wong said: "The talk about sports and weight-loss problems, we must first understand the movement and energy expenditure mechanisms. Campaign process, energy consumption in three stages, namely, glucose metabolism, fat metabolism, protein metabolism, weight loss through fat consumption to achieve results. "
Swimming at the beginning, at the stage of anaerobic exercise. Energy consumption depends mainly on anaerobic glycolysis of sugar, this phase of the campaign is very intense, people shortness of breath, lack of oxygen, there will not use the fat. Continue movement continues, the body entered the period of aerobic exercise. In the ensuing hour, the moderate-intensity exercise state, the energy supply from aerobic metabolism of sugar to provide energy. This one-hour time it also will not burn up the fat. If you insist on going movement, then began to come from the fat consumption of fat, aerobic metabolism. Therefore, swimming in at least one hour before beginning to exercise or weight-reducing effect, some people exercise a lack of time or amount of exercise is not enough, it can not be effective.
Professor Huang reminded, swimming, weight-loss but also paying attention to diet. However, the people after exercise has a "super-compensation" phenomenon. Simply put, that is, the human body to adapt to raising the level of the next phase of the campaign, after each exercise should intake more energy than ever before, which is the body's self-protective measures. So, after swimming, people often eat well sleep incense, consumption of calories has to be recovered, even more than consumption of more than. Therefore, pay attention to diet, particularly in a period of time after cessation of exercise are most likely to weigh more than the original level. Many people exercise to lose weight this is an important reason for failure.
Therefore, the physical thin people through short-term persistence of the swimming exercise, can often quickly become strong. The obese people are often after swimming more easily than before hungry, and intake of energy are also more numerous. Seem to be more suitable for swimming, would like to take to make itself stronger person, and less suitable for those who use it to lose weight, especially those who exercise to lose weight irregular.
Professor Huang, for example, a matter of fact, as long as compare swimmers will find that the swimmers who have seen what is thin? Whether men and women, generally more plump body shape, skin smooth and mellow, this is more the performance of subcutaneous fat. Full of water massage and body temperature than people with low temperature, easy birth of human subcutaneous fat growth.
