What are the benefits of swimming? In a blink of an eye, summer has come and the weather is getting hotter and hotter. At this time, we might as well go swimming in the swimming pool, because swimming can not only make us cooler, but also bring us many benefits. Let me share the benefits of swimming with you, and interested friends will learn about it.

What are the benefits of swimming? What are the benefits of swimming?

First, swimming can improve heart and lung function.

When swimming, people lie in the water. Because of the buoyancy of water, people weigh only a few kilograms in water. When people exercise on land, all organs must bear much more weight than in water. In contrast, the load when swimming is much less than that brought by land activities. Lying flat in water can also reduce the resistance of blood circulation system and the load of supporting organs. When swimming, all postures require full extension of the spine, which is very effective in preventing hunchback and scoliosis.

Swimming can also enhance the function of the respiratory system. When swimming, people's chest and abdomen are under the pressure of water. When swimming, the chest pressure is 120- 150 Newton, which makes breathing difficult. Long-term swimming exercise can increase breathing depth and lung capacity. The vital capacity of excellent swimmers can reach 5000-7000 ml, while that of healthy men is about 3500 ml.

Taking part in swimming exercise can improve the adaptability to water temperature and air temperature and enhance physical fitness. Many children with asthma have strengthened their physique and defense against cold through swimming exercise, reduced the number of asthma attacks and even cured asthma.

Swimming can also effectively improve and improve the function of people's cardiovascular system, especially taking part in swimming exercise from an early age, which can promote the development of cardiovascular system, which is irreplaceable by other sports. When people lie flat to stand still, due to the effect of gravity on blood, the blood accumulated in leg veins is about 600 ml, so the heart volume decreases. At this time, the body has to speed up the heartbeat frequency to maintain the blood output of the heart per minute. This is why people have a faster heart rate and a smaller heart volume (about 600 ml) when standing and lying down. On the contrary, when they change from standing to lying down, the hydrostatic pressure in the body decreases and blood flows from all parts of the body to the chest. Due to the action of gravity, the pressure on the heart decreases, making it easier for blood to return to the heart than when standing, so the heart volume increases (about 740 ml) and the heart rate slows down.

When swimming, you will feel weightless because the hydrostatic pressure in your body is offset by the buoyancy of water. The pressure of water will push 700 ml of blood from the superficial vein back to the chest cavity, so the central venous pressure will increase significantly. Results The cardiac blood flow increased, the cardiac volume increased (about 840 ml), and the heart rate slowed down accordingly. Long-term swimming, especially long-term swimming, can effectively increase the heart volume and reduce the heart rate at rest. An excellent athlete's morning pulse can reach about 40 times/minute, and there is a phenomenon of function saving when completing quantitative work. Swimming can also increase the elasticity of blood vessel wall, increase the number of capillaries, obviously improve the function of circulatory system, keep blood pressure in a good state, and obviously increase the pulse pressure difference.

Swimming can effectively consume body fat, especially when swimming for a long time, because the difference between water temperature and body temperature is about 10oc, which will accelerate heat dissipation and increase consumption. Many people feel hungry or hungry after swimming. Swimming can control diet and is undoubtedly a good way to lose weight. Experiments show that swimming consumes more calories than long-distance running, gymnastics and wrestling athletes. The heat dissipation of swimming at 200c is twice that of basal metabolism, and the heat consumption of swimming at 50c for 5 minutes is equivalent to long-distance running on land 1 hour.

Modern scientific research shows that there is a cell called T lymphocyte in human immune function, and its activity and quantity are decreasing with age. Therefore, people are prone to some diseases after middle age, such as stomach diseases, coronary heart disease, rheumatoid arthritis, bronchitis, tumors and so on. The occurrence of these diseases is closely related to the decline of human immune function, and insisting on swimming or cold water swimming (winter swimming) is one of the most effective prescriptions.

Swimming also has the effect of beauty and skin care. Swimming is carried out in water, and long-term high humidity environment is beneficial to skin moisturizing and maintenance. Swimming can not only moisturize, but also massage the skin.

Secondly, swimming is a good way to educate children.

Entering the 1990 s is the only child era. Some of their weaknesses, such as their inability to bear hardships and weak will, have caused many parents headaches. However, many parents are willing to let their children swim. The purpose is not only to learn a self-protection skill, but also to exercise your body. More importantly, let children exercise their will and quality in the process of learning to swim, and cultivate good habits of obeying discipline.

Swimming is a panacea for young and middle-aged people to reduce stress and restore energy.

Swimming is a good means to regulate mood. When people are working and studying nervously, they are often in a state of anxiety, melancholy and impetuousness. As long as you swim in the water a few times, you will form a special massage hairstyle through the massage and impact of the water flow on your body. This natural massage not only relaxes the muscles, but also relaxes the nervous nerves immediately, expelling the negative psychological factors that have side effects on the body and restoring a positive and healthy psychological state. At the same time, swimming is a very social sport, and most of them go hand in hand. If you swim in one place for a long time, you will meet a group of new friends. These people will get together to chat and take care of each other, which will make people spiritually satisfied.

Fourthly, swimming is a good way for the elderly to keep fit.

Swimming load intensity is relatively low, which is a method suitable for the elderly to entertain and keep fit.

Old people who take part in water sports are not necessarily good swimmers. Walking in the water or carrying a lifebuoy can achieve the purpose of exercising. Old people who are too fat to move on land can exercise in buoyant water to enhance muscle strength, promote cardiovascular function and improve the flexibility and flexibility of joint ligaments. At the same time, water sports are beneficial to the treatment and physical recovery of chronic diseases in the elderly.

What are the benefits of swimming? What are the benefits of swimming in winter?

1. People who take part in winter swimming generally benefit.

Through winter swimming, I have improved my quality of life, eating well, sleeping well, being energetic and quick-thinking, seldom catching a cold and suffering from other diseases.

2. Winter swimming can promote endocrine.

After the human body is strongly stimulated by cold, it is immediately reflected to the pituitary gland, adrenal gland, pancreas, gonad and other glands through the nervous system, and each gland secretes corresponding hormones, which are called neurohumors. Then the physiological functions of the corresponding organs are adjusted through the corresponding nerve centers to establish a new balance. It stands to reason that with the increase of age, the secretory function of each gland should have decreased, but experiments have proved that the secretion of thyroid hormone in winter swimmers has increased.

4, can enhance their own immunity.

Immunity refers to the body's ability to prevent and resist invasive pathogens. After winter swimming, many indexes, such as lymphocytes, leukocytes, phagocytes, immunoglobulins, etc. , are significantly higher than before the winter swimming. And these indicators can show that people's immunity is increasing.

5. Winter swimming enhances the function of digestive system.

Because of excessive heat energy consumption and enhanced digestive ability, the appetite is greatly increased and the metabolic function of the whole body is generally enhanced.

6, can enhance cardiopulmonary function.

After winter swimming, myocardial contractility is enhanced, blood circulation is accelerated, and the functions of various systems of the body are well promoted and developed.

7. Winter swimming increases blood vessel elasticity.

Like vascular gymnastics, winter swimming can increase blood vessel elasticity and speed up blood flow, reduce and sprint fat particles and cholesterol deposited on blood vessel walls, alleviate and delay arteriosclerosis, and prevent thrombosis and coronary artery infarction.
