History
Swimming is one of the favorite sports of all ages. Ancient swimming, based on existing historical materials research, domestic and foreign produce more consistent view is at living in rivers, lakes, sea and in the vicinity of the ancient people. Them in order to survive, will have to capture waterfowl and fish in the water for food, through observation and imitation fish, frogs and other animals in the water swimming action, and gradually learned how to swim.

Competitive swimming, from the first Olympic Games (1896) on the inclusion of the official Olympic program. To the present, various tournaments, major international competitions continue to promote the development of competitive swimming, making it more sophisticated technical movements, creating one after another excellent results. History and Development since ancient times, whether for hunting one, avoid predators or to help themselves, swimming is an important event of shipwreck survival skills.

Value of swimming exercise
Cardiovascular effects: Swim to improve the cardiovascular system have a very important role. Cold stimulation by heat regulation can promote blood circulation and metabolism; addition of water pressure and resistance of the heart and blood circulation also play a special role in swimming, swimming in the water when the body is exposed to water pressure had reached every cm 0.02-0.05kg, with the increasing depth of the dive, changes in physical conditions, the pressure will be increased to accelerate the swimming speed will increase the pressure load, the atrial and ventricular muscle tissue can be strengthened heart chamber The capacity can be increased gradually to reduce the number of heart beats, this can save activity of the heart, the system is able to improve the blood circulation, an increase in the pressure reduction sheets rest, decreased systolic blood pressure, Therefore, the blood pressure value becomes more favorable; elasticity of blood vessels is increased. According to the experts to statistics, the average person in a quiet state of heart beats per minute to about 66-72 times the output of each blog is about 60-80 ml, and long-term swimming exercise people in the same situation just shrink about 50 times, Each output has reached Bo 90-120 ml. Effects on the respiratory system: When swimming exercises, metabolism and cardiovascular system working process of saving, are inseparable from the large amount of oxygen, however, due to the oppression of the chest and abdomen of water, increasing the difficulty to inhale, special test has been done, swimming When the human thorax subject to 12-15kg water pressure, so in order to make the body get enough oxygen, respiratory muscles must constantly overcome this pressure; another breath while swimming underwater are generally completed, and water density is much greater than the density of air, so in order to force the breath must, so whether it is able to inhale or exhale increased respiratory muscle contraction, which can enhance the function of the respiratory system, increase lung capacity. General Health Men's lung capacity is 3000-4000 ml, and often engaged swimmers can reach 5000-6000 ml. Effect on human skin: During swimming, the water temperature to stimulate the body to ensure a sufficient temperature. Skin, blood vessels involved in important regulatory role, cold water can stimulate the skin when blood vessels, prevent heat spread to the body. While the body produces heat and stepped up, the skin blood vessels to dilate, improving blood supply to the skin blood vessels, so that long-term adherence to exercise can help strengthen the skin's blood circulation. In addition, liquid water is very soft, but due to the action of water waves constantly rub against human skin touch, which is the skin better to relax and rest, so often swim workout person has one smooth white, soft skin. Other effects: As we all know, we live in a three-quarters full of water sphere, so in life would inevitably have to deal with water, which is not only just a sport swimming, more importantly, it is a rare life tools and skills . It permeates our lives in many areas: water resource development, scientific investigation, flood rescue, ambulance and so must have a skilled salvage swimming skills as a backup, in order to have the protection of life. After swimming Notes: Swimming is a good way to cool off, and it is the best choice for physical fitness. Many students take advantage of a holiday vacation with water close, but after the swim, some people's eyes tend to congestion, aches, if ignored, either of which is likely to worsen cause serious eye disease.

But I believe there will still landlubbers in, like I did a few weeks ago, here to talk about their own experiences learning to swim a little. Adult learn to swim once you have the hang naturally learn quickly, up to two can swim very good. At least to learn to be like in Shanghai when a friend told a week, time is naturally a bit long. Of course, the water is beginning to close contact with the water, and try to close and intimate with her, to become familiar with her temper go, otherwise you'll swing around in the water, center of gravity, in fact, as long as you like a familiar people like her to touch it. Then is to learn to bury his head in the water, so that they do not want to choke to ensure water, and the habit of feeling in the water, in the water before you feel should be in the dark, can not see what is, I did not expect to wear glasses to see the world from the water, turned the same transparent and clear. When you can make the head of the water with ease when you can start trying to make your own body floating in the water up, this is the most important step, as long as the learned, basically you will swim, of course, still those difficult, difficult person does not, find a way to put the body floating in the water, do not sink, this is a skill, which uses physical knowledge learned in high school, and can be seen from the force balance principle, the human body Like a lever, like the middle of the navel is the fulcrum, head high, legs, of course it will sink, the body does not naturally float up, of course, the head of the sinking of this phenomenon are in the minority, do not believe try it on the line a. Therefore, the body naturally relax, do not be nervous, arms naturally on the water, do not be too persistent, and soon your body can float in the water, do not say you never learned to swim, larvae in the mother is like when you are in Like water naturally, as long as you can wake up feeling. Well, do not worry, you can quickly learned that when your body can freely float in the water, then, you can slide the arms, the use of water resistance, put you forward, OK, you can water forward. Then, the last step, so that my legs slap the water, pay attention, do not hit the legs bent, such as your arms and legs with a very understanding when, of course, you will learn to swim, and then, according to your own habits and characteristics, to consciously practice, you will become a swimmer. Do not believe, you can try, of course, only methods, no practice is never learn to swim, then I wish you success.

(3) swimming exercise can enhance the function of body organs, systems, chronic disease by swimming exercise, can enhance the growth unsound organ system functions, so that has been weakened organ system functions have been restored and enhanced, so that the disease get treatment. (4) swimming workout can cultivate character, strengthen their will, to train people to wrestle with the fighting spirit of nature, but also enable patients to establish the confidence to overcome the disease, to overcome the fear of trouble on the negative mental illness, which is very conducive to a healthy recovery and treatment of disease. (5) Enhanced myocardial function People in the water sports, the various organs are involved, energy and more, also will accelerate blood circulation to supply more nutrients moving organs. Accelerate blood velocity will increase the load on the heart, making it beat frequency accelerating contraction strong. Often swim, heart function is excellent. The average person's heart rate is 70 - 80 beats / min, stroke volume of 60 - 80 ml. Heart rate and often swim up to 50 - 55 / min, a lot of good swimmers, heart rate can reach 38 - 46 beats / min, stroke volume up to 90 - 120 ml. Role of water when swimming easy-limb blood return to the heart, the heart rate. Swim there will be significant long-term movement of the heart increases, a strong contraction, blood vessel wall thickness increased flexibility to increase, stroke volume increases. So, you can swim out a powerful exercise heart. (6) enhance immunity The pool water temperature is often 26 degrees to 28 degrees is soaked in water for fast heat dissipation, energy consumption. To supplement the heat of the body as soon as possible, in order to balance the need for cold, nervous system will respond quickly, so that the body metabolism to speed up and enhance the body's ability to adapt to the outside world, to withstand the cold. Who regularly participate in winter swimming, because thermoregulatory function improved, not easy to colds, but also improve the human endocrine function, pituitary function is increased, thereby increasing resistance to disease and immunity. (7) Weight Loss Swimming body directly immersed in water, the water resistance is not only large, but also very good thermal conductivity, heat faster, thus consuming more calories. Like a freshly cooked eggs in the air cooling rate, far less than in cold water quickly proved: people running calories consumed 20 minutes in a standard swimming pool, representing the same speed on land one hour In 14-degree water consumed to stay one minute up to 100 kcal calories, the equivalent of the heat for 1 hour with the temperature of the air emitted. Thus, water sports, will make a lot of people who want to lose weight, get a multiplier effect, so swimming is one of the most effective exercise to keep fit. (9) to strengthen lung function Mainly by breathing lung, pulmonary function is determined by the strength of the strength of respiratory muscle function, exercise is one of the effective means to improve and enhance lung capacity. It has been determined: Swimming man's chest when subject to pressure of 12-15 kg, plus cold water to stimulate muscle contraction, breathing becomes difficult, forcing people to breathe, to increase the depth of breathing, so the amount of oxygen inhaled to meet the body's needs. Usually vital capacity was about 3200 ml, respiratory difference (maximum inspiratory and expiratory chest expansion and narrowing of the difference) is only 4-8 cm, while the maximum oxygen uptake of strenuous exercise 2.5 - 3 liters / min, 10 times larger than the quiet time; while swimmer's lung capacity up to 4000-7000 ml, breathing difference reaches 12-15 cm in maximal oxygen uptake when strenuous exercise is 4.5 - 7.5 l / min, compared with 20 during the quiet increases times. Swimming prompting people developed respiratory muscles, chest increases, increased lung capacity, and inspiratory alveolar opening more ventilation smooth, extremely beneficial to health. (10) Skin Care When swimming in the water on the skin, sweat glands, sebaceous glands erosion, played a very good massage, promote blood circulation, make the skin smooth and elastic. In addition, the movement in the water, greatly reducing the salt in sweat on the skin irritation
