Significance and value of swimming. Swimming is our most common sport. Swimming is a simultaneous exercise of all limbs. Long-term swimming will make your limbs more flexible. Proper swimming is good for our health. Let's take a look at the significance, value and related contents of swimming.
The significance and value of swimming 1 1, to ensure the safety of life, we can see a large number of drowning accidents every year, and accidents often come off guard. Don't think that this matter is far away from us, we should plan ahead. Learning to swim can save lives in an emergency. Many countries in the world have listed swimming as a compulsory sport for students, and China has also advocated and implemented it in some areas, and listed swimming as a subject for the senior high school entrance examination.
2, enhance myocardial function, because of the great underwater resistance and pressure, swimming needs more energy to speed up the heart rate and increase the cardiac output. Long-term persistence in swimming leads to an increase in heart volume with exercise, strong myocardial contraction, slow resting heart rate, increased stroke output, thickening of blood vessel wall, increased elasticity and improved efficiency of cardiovascular system.
3, enhance the resistance, the swimming pool temperature is generally around 26℃~28℃, which consumes a lot of energy underwater and dissipates heat quickly. In order to supplement the heat emitted by the body as soon as possible and meet the needs of cold and heat balance, the nervous system will respond quickly, thus accelerating the metabolism of the human body, enhancing the adaptability of the human body to the outside world and resisting the cold. People who often take part in winter swimming are not easy to catch a cold because of the improvement of body temperature regulation function, and can also improve the endocrine function of human body and increase the function of pituitary gland, thus improving the resistance and immunity to diseases.
4. Effectively relieve the pressure on the spine, and have a good soothing effect on diseases such as lumbar disc compression. Because of posture, the pressure on the intervertebral disc will be reduced, so the symptoms of lumbar intervertebral disc or cervical spondylosis can be improved. When swimming, the upper limbs can effectively move the shoulder joint and back muscles when paddling hard, and the action of raising the head and inhaling can move the cervical joint. But holding your head up and inhaling and bending over your desk are just two opposite movements, which can promote the repair of strained muscles and ligaments.
5, effective decompression, modern people are more or less depressed, from life pressure, work pressure. Proper exercise can stimulate physical and mental excitement, thus alleviating the influence of negative emotions. Running, playing ball and fitness are all easy to cause fatigue, and it is not easy to persist, but swimming is not easy. When swimming underwater, people are not easy to feel tired, and sometimes even become more excited when swimming, which is usually felt after landing. Therefore, we should pay attention to proper exercise, two or three times a week, one hour to one and a half hours each time.
6, lose weight and shape, swimming is a whole body exercise, which can promote the blood circulation of the whole body muscles. When rowing in the water, it can play a good role in exercising and massaging the muscles of various parts of the human body, thus improving the strength and circumference of muscles, making muscles more developed, improving and increasing the basal metabolic rate, and being beneficial to losing weight. Sticking to long-term regular exercise can make your figure straighter and more symmetrical. It is rumored that swimming will lead to shoulder width, but how many people will exercise like athletes? Swimming will only make your muscles stronger, your trapezius muscles smaller and your skin more textured.
Significance and value of swimming. The meaning of swimming.
Swimming not only makes our physical fitness better and better, but also has deeper reasons. The following are the swimming feelings expressed by netizens. If you swim often, will you feel this way? Swimming is the most relaxing time for the whole body.
The pleasure of swimming
The whole body is immersed in water, and it doesn't take much effort to swing your hands and feet. This pool of transparent liquid holds up the whole body and has a sense of pleasure from gravity. Sometimes when I am tired of swimming, I lie on my back in the water, and what I hear in my ear is the gentle beating of water waves, which is quiet and comfortable. I think I had a long dream. I trudged across Qian Shan in my dream and finally found my paradise. The grass here is delicious and colorful, and the traffic in the building is busy. And you just want to rest here at sunrise and sunset, like a pool of still water without a ripple.
I also quietly went to the swimming pool when I was depressed, exhaled and lay under the water, feeling myself slowly melting in the water. The pool was swaying gently, and I felt my gloomy thoughts were diluted in the liquid with the smell of hypochlorous acid.
Only your time.
The meaning of swimming is not only to be happy, but to accept yourself deeper inside. Swimming will make you very relaxed, especially when you have a lot of troubles every day and want to jump into the water and think nothing. No matter how busy you are every day, you will report to the swimming pool. Seeing my aunt's smile in the swimming pool, I felt very practical.
The time to jump into the water is yours, just you and me. Adults need to be alone too much, and they need to have a time that belongs only to you. Once this time has passed, it's hard to give up. When I am in the water, I will think about many things, even recite the text! Yes, you are right. You read the text silently in the water and change the number of breaths in English, French and Japanese in the water. I don't want to swim hard when I'm in a bad mood. Swimming doesn't hurt your joints. My knees were scarred before running, so swimming is very comfortable, feeling like a fish and free.
Shape; appearance
If a girl swims, it is very helpful for shaping. After swimming continuously for a month, you will see that your stomach is getting smaller and your ass and chest are getting tighter.
Exercise is a habit. When you get used to it, it becomes a part of yourself.
Many people ask if swimming can lose weight. To tell the truth, whatever exercise you do will only make you strong.
Some people think swimming is expensive. The swimming pool near my home visited 450 yuan 20 times, and the previous year 1800. In fact, this money is good for office workers. If I go somewhere else, I'll take my swimsuit and buy it. Some swimming pools are unlocked, so I can prepare an emergency myself.
The problem of swimming pool water
There is also the problem that the swimming pool water is not clean. Cheap swimming pool water is not clean, and it is too expensive to go. Therefore, there are no special circumstances, I will travel in a fixed way. If it really doesn't work, I'll make do with the regiment.
If you feel uncomfortable after swimming, you can buy a chlorine-removing shower gel, wash it twice in the bathtub, wash it once with this shower gel, and then use what you usually use, and the effect will be much better.
Some girls think swimming is not good. Well, the problem is, if you are afraid that the water is not clean, bring a tampon and wash it with emulsion. I have seen a problem before. A girl who swims for one year gets gynecological diseases. In fact, children are not too serious about taking a bath in the swimming pool, and often run away after taking a bath inadvertently, so girls must pay attention.
Significance and value of swimming. The significance of learning to swim
First, swimming gives children a healthy and beautiful body.
Swimming can make all parts of the body of teenagers and children get comprehensive and coordinated exercise and development, shape beautiful bodies and enhance the coordination of the body. The body is in a horizontal state in the water, and the joints of limbs and spine will not be impacted by the reaction force from the ground during exercise. This is not only not easy to damage, but also conducive to the elasticity and flexibility of the skeletal system, better promote the growth and development of bones, and correct bad posture.
Second, swimming can cultivate a cheerful and sunny personality.
Swimming can relieve psychological stress, and people can feel completely relaxed when swimming. At the same time, people's social skills and cheerful personality can be cultivated by communicating with teammates, coaches and even strange partners and friends who unify the swimming pool. Learn to make friends and walk into life.
Thirdly, swimming can cultivate tough willpower and courage to overcome difficulties.
Learn to be rigorous and pursue perfection from every adjustment of swimming style, learn to go all out in every whistle of the coach, and sprint to the wall in every game. The training of swimmers is target training, which aims to break through the existing time and finally achieve the goal. After several years of training, looking back, the characteristics of being spoiled and afraid of hardship have long evaporated in the swimming pool.
Fourthly, swimming cultivates a kind of spiritual enjoyment and life taste.
When swimming, you need to sink into the water to experience the subtlety of the water, adjust the subtle movements in the quiet water, listen to the music in the water, and discover the microscopic and grand world that you can't feel on land. Children learn to swim from an early age, which can cultivate elegant taste and lifestyle and exercise a calm gentleman temperament.
Learn the main classification of swimming.
Practical swimming
The swimming mode with great value in military, production and life service is called practical swimming. For example, crawl swimming (freestyle), breaststroke, side swimming, diving, treading water (standing swimming), water rescue, military swimming and backstroke.
competitive swimming
Refers to swimming events that have specific technical requirements and compete in accordance with swimming competition rules. It can be divided into two categories: competitions in swimming pools and competitions in open waters. Such as freestyle, breaststroke, backstroke, butterfly (also known as dolphin swimming) and individual medley composed of these four kinds of swimming, as well as relay swimming competition swimming. Competitive swimming mainly determines the ranking of swimming according to the speed, which is called competitive swimming according to the national swimming competition rules.
Competitive swimming originated in Britain and Australia, and was later introduced to other countries. From the middle of19th century to the beginning of 20th century, swimming competitions began to be popular all over the world, and swimming clubs were established one after another. The British Amateur Swimming Association (formerly known as the Metropolitan Swimming Association) was established in 1869, which is the earliest national swimming association. From 1850 to 1860, there are international swimming competitions between Britain and Australia. 1894 When the International Olympic Games was founded in Paris on June 6th, swimming was listed as one of the Olympic events in 1894. As for FINA, it was established in 1908.
water ballet
Also called "artistic swimming". It is a competitive sports event that integrates dance, gymnastics, swimming and other projects, and requires higher requirements for sports figure, swimsuit, headdress, music, movements and arrangement. It is divided into single, double and team events. Through the movement and music of athletes' limbs on the water, it shows all kinds of beautiful movements and various forms of artistic skills, giving the masses a good enjoyment, so it is known as "water ballet".
In today's society, swimming is also a form of exercise for everyone. Many families choose swimming when they go out for activities. This is an exercise, which not only exercises their bodies, but also their vital capacity. Many parents choose to train their children to choose swimming, so that when their children have a large lung capacity, their bodies will gradually become stronger and they will have certain immunity to foreign patients.
The health value of learning to swim
1, enhancing myocardial function.
When people exercise in water, all organs participate in it, which consumes a lot of energy, accelerates blood circulation and provides more nutrition for sports organs. The acceleration of blood speed will increase the load on the heart, make the heart beat faster and contract strongly. People who swim regularly have excellent heart function. The average person's heart rate is 70-80 beats per minute, and the stroke output is 60-80 ml. Frequent swimmers' heart rate can reach 50-55 beats/min, many excellent swimmers can reach 38-46 beats/min, and the stroke output is as high as 90- 120ml. When swimming, the role of water makes it easy for limb blood to flow back to the heart and accelerate the heart rate. Long-term swimming will obviously increase the activity of the heart, contract strongly, increase the thickness and elasticity of the blood vessel wall, and increase the stroke output. Therefore, swimming can exercise a strong heart.
Step 2 Enhance resistance
The water temperature in the swimming pool is often 26 to 28 degrees, so soaking in water dissipates heat quickly and consumes a lot of energy. In order to supplement the heat emitted by the body as soon as possible and meet the needs of cold and heat balance, the nervous system reacts quickly, accelerating the metabolism of the human body, enhancing the adaptability of the human body to the outside world and resisting the cold. People who often take part in winter swimming are not easy to catch a cold because of the improvement of body temperature regulation function, and can also improve the endocrine function of human body and increase the function of pituitary gland, thus improving the resistance and immunity to diseases.
Step 3 lose weight
When swimming, the body is directly immersed in water, which not only has great resistance, but also has very good thermal conductivity and fast heat dissipation, so it consumes more heat. Like a boiled egg, the cooling rate in air is far less than that in cold water. Experiments show that the heat consumed by a person running in a standard swimming pool for 20 minutes is equivalent to running at the same speed 1 hour on land, and the heat consumed by staying in water with 100 minutes is as high as 100 kcal, which is equivalent to being in air with the same temperature. In addition, swimming diet can avoid sports injuries of lower limbs and waist. When you exercise on land to lose weight, your body (especially lower limbs and waist) will bear great gravity load because of the heavier weight of obese people, which will reduce your exercise ability and make you tired easily, thus greatly reducing your interest in losing weight and damaging the joints and bones of lower limbs. When swimming in water, a considerable part of obese people's weight is borne by the buoyancy of water, which makes their lower limbs and waist much easier and greatly reduces the risk of joint and bone injury. It can be seen that water sports make many people who want to lose weight get twice the result with half the effort. Therefore, swimming is one of the most effective aerobic exercises to keep healthy.
4. bodybuilding
When swimming, people usually use the buoyancy of water to lie prone or supine in the water, so that the whole body can be relaxed and stretched, so that the body can develop comprehensively, symmetrically and harmoniously, and the muscle lines can be smooth. Exercise in water reduces the impact of the ground on bones, reduces the probability of bone aging, and the joints are not easy to deform. The resistance of water can increase people's exercise intensity, but this kind of intensity is very soft, which is different from the equipment training on land. It is easy to control the training intensity in aerobic area, and it will not grow stiff muscle blocks, which can make the whole body lines smooth and beautiful.
5. Enhance lung function
Breathing mainly depends on the lungs, and the strength of lung function is determined by the strength of respiratory muscle function. Exercise is one of the effective means to improve and increase vital capacity. According to the measurement, when swimming, people's chest is under the pressure of 12- 15 kg. Cold water stimulates muscle contraction, making it difficult to breathe, forcing people to breathe hard, increasing the depth of breathing, and making the amount of oxygen inhaled meet the needs of the body. The average person's vital capacity is about 3200ml, and the breathing difference (the difference between the expansion and contraction of the chest circumference at the maximum inhalation and exhalation) is only 4-8 cm. The maximum oxygen uptake during strenuous exercise is 2.5-3 liters/minute, which is 10 times higher than that at rest. The swimmer's vital capacity can be as high as 4000-7000ml, the breathing difference can reach 12- 15cm, and the maximum oxygen uptake during strenuous exercise is 4.5-7.5 liters/min, which is 20 times higher than that at rest. Swimming makes people develop respiratory muscles, increase chest circumference, increase vital capacity and open more alveoli when inhaling, which is very beneficial to health.
6, skin care
When people swim, the water washes away the skin, sweat glands and fat glands, which plays a good massage role, promotes blood circulation and makes the skin smooth and elastic. In addition, when exercising in water, it greatly reduces the irritation of salt in sweat to the skin.
7, improve the ability of muscle system
Swimming is a whole-body exercise, which can mobilize more muscle groups to participate in metabolism and energy supply than other sports. Although swimming can't build thick and bulging muscles, it can improve the strength and coordination of many muscles, especially the muscles of trunk, shoulder straps and upper limbs. Because swimming in water needs to overcome great resistance, and swimming is a periodic exercise, long-term exercise can improve muscle strength, speed, endurance and joint flexibility.
Another great advantage of swimming is the improvement of flexibility. This allows people to continue swimming when they are unable to engage in other sports activities due to age restrictions. Because swimming has a wide range of physical activities, people who swim often become more flexible and soft. Moreover, the correct swimming technique requires the muscles to stretch before the contraction force, which is conducive to continuously improving flexibility and strength.
8. Improve the thermoregulation mechanism.
Because the temperature of water is generally lower than that of air, and the thermal conductivity of water is dozens of times stronger than that of air, people dissipate heat much faster in water than in air. Regular swimming can improve the ability of body temperature regulation, so as to be more able to withstand the changes of external temperature. Especially in winter swimming, this improvement is particularly obvious.
9. Prevention, treatment and rehabilitation of diseases
Due to the stimulation of cold water, long-term swimming exercise can enhance the body's cold resistance and adaptability to the environment, prevent colds and other diseases, and make the body stronger day by day. Because the body lies flat when swimming, plus buoyancy, the spine can be fully stretched, which has a certain rehabilitation effect on some spine patients. Swimming can also be used as exercise prescription to treat some chronic diseases, such as chronic gastrointestinal diseases or chronic bronchial asthma. For some people who are not suitable for upright exercise, such as obese patients, if they take running and other ways, their legs and feet will be overloaded due to gravity, which will easily lead to injuries. At this time, swimming is a good alternative to exercise.
