Advantages and disadvantages of swimming, swimming is known as the "king of sports", mainly because compared with other sports, swimming is the least harmful to the body, swimming is an aerobic exercise, and frequent swimming can lose weight. Let's understand the advantages and disadvantages of swimming.
Advantages and disadvantages of swimming 1 First of all, the advantages of swimming
1, swimming can enhance 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. 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.
2. Swimming can 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.
Swimming helps to burn fat and 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. It can be seen that water sports make many people who want to lose weight get twice the result with half the effort, so swimming is one of the most effective fitness exercises.
Swimming can improve the flexibility of the body.
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. The training intensity is easily controlled within the aerobic range, so that stiff muscle blocks will not grow and the whole body lines will be smooth and beautiful.
Swimming helps to relieve stress and depression.
Endorphin is a kind of hormone that makes people feel good, which can improve people's mood, while swimming can effectively stimulate the secretion of endorphins and help people relieve the pressure of daily work and life. Besides, swimming can make people fully relax like yoga. If combined with regular deep breathing, the effect will be better. At the same time, swimming can calm people down, eliminate external interference, become more focused, and naturally reduce people's tension and depression. Related studies have confirmed that swimming can also help restore brain function damaged by stress through a process called hippocampal nerve regeneration. So, if one day you feel out of shape, you might as well put on your swimsuit and jump into the pool to release your emotions!
6. Swimming can improve skin quality.
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. Swimming can shape muscle lines.
People can strengthen their muscles by swimming. Running can improve the strength of people's legs, while swimming requires the coordinated efforts of muscles in all parts of the body, so the muscles of the whole body can be exercised. Push your legs back, pull your arms, stretch and contract your back, tighten your abdomen, increase your leg strength and keep your hips stable. These basic swimming movements make every muscle of the whole body excited, which not only enhances the strength, but also avoids the possible consequences of muscle asymmetry caused by the movement of equipment.
8. Swimming can improve bones.
Once upon a time, many people scoffed at the idea that swimming could improve bones. After all, it seems that only weight exercises can achieve this goal. However, a study published in the Journal of Applied Physiology supports this view. Because there are some moral controversies in the direct bone examination on human body, the researchers take mice as the research object and divide them into three groups: running group, swimming group and control group (no exercise). Research shows that running can improve the bone mineral density, and compared with the control group, the swimming group performs better in bone mineral density and thigh bone weight. Obviously, if you want healthier bones, swim!
9. Swimming can reduce the risk of inflammation.
As we all know, swimming helps to enhance myocardial function and improve cardiovascular health. Related research further confirms that aerobic exercise such as swimming helps to reduce the risk of inflammation, thus preventing diseases such as cardiac atherosclerosis caused by it. In addition, reducing the inflammatory risk of the whole system can also alleviate the deterioration of many other diseases, with many benefits.
Swimming can relieve exercise-induced asthma.
Nothing is more sad than breathing difficulties during exercise! Compared with outdoor exercise in a gym with dry air or full of pollen, people can breathe humid air and improve their respiratory function when swimming. Studies have confirmed that swimming can not only relieve asthma symptoms, but also fundamentally improve lung health. The most typical example is South Korean swimmer Park Tae hwan, who suffered from asthma when he was a child. Later, his parents asked him to practice swimming to help relieve his symptoms. As a result, I not only lost my asthma, but also became an Olympic champion, killing two birds with one stone!
Swimming can make people smart.
Exercise can improve people's mental state, but can swimming really make people smart? Researchers from Australia studied a group of children who took part in swimming training courses, and took another group of children who did not learn swimming as the control group. The results show that children who often swim are faster and better than the control group in mastering language, learning to ride bicycles, building self-confidence and physical development. In addition, because swimming needs to calculate the swimming distance repeatedly, people who swim frequently are also better at arithmetic!
Swimming can prolong life.
Everyone knows that exercise can improve health and prolong life, but research further confirms that swimming is the best in both aspects. Researchers at the University of Southern California followed 40,547 men aged 20-90 for 32 years. The results show that the mortality rate of men with swimming habits is nearly half lower than that of men who often run, walk or don't exercise. It can be seen that swimming is definitely a good way to live longer!
Second, the disadvantages of swimming
1, susceptible to infectious diseases
Because there are many people in the swimming pool, there will be many infectious bacteria in the water, and people with poor immunity will be easily infected if they stay in the water for too long.
2, causing cramps
Swimming for a long time can cause muscle fatigue and cramps, and in severe cases, it may drown, which is also a major disadvantage of swimming.
Advantages and disadvantages of swimming 2 benefits of pregnant women swimming
1, the change of pregnant women's body position in water is beneficial to correct fetal position and promote natural delivery.
2, increase lung capacity, let the mother hold her breath for a long time during childbirth, and shorten the labor process.
3, frequent swimming, you can gradually consume excess calories in the body, thus preventing pregnancy poisoning.
4, can improve mood, reduce pregnancy reaction, reduce pregnancy headache, and also have a good impact on the development of fetal nervous system.
5, can reduce the oppression of the fetus on the rectum, and promote the blood return in the pelvis, eliminate congestion, and help prevent constipation, edema of the lower limbs and varicose veins.
6. The heavy pregnant uterus is supported by water buoyancy, which can reduce the burden of the psoas and dorsal muscles supporting the pregnant uterus, thus alleviating or eliminating the common symptoms of low back pain during pregnancy.
7. When swimming, the muscles of the whole body participate in the activity; Coupled with the "massage" of water on skin and blood vessels, it can promote vigorous blood circulation, not only enhance the physique of pregnant women, but also benefit the development of the fetus.
8. Sunbathing is good for swimming. Ultraviolet rays in sunlight not only have bactericidal effect, but also can convert subcutaneous dehydrocholesterol into vitamin D3, which promotes the absorption of calcium and phosphorus and is beneficial to fetal bone development.
9. Regular swimming can also help pregnant women keep fit, especially for the recovery of postpartum body shape.
Advantages and disadvantages of swimming 3 advantages of baby swimming
Stimulate and promote the development of cranial nerves and significantly improve the level of intelligence.
As we know, the cranial nerves are connected with the peripheral nerves of all parts of the body. Therefore, when the baby moves freely in the water, all kinds of movements are directly controlled and regulated by the nervous system, and the activities of muscles and joints in turn stimulate the cerebral cortex nerves, thus promoting the rapid development of brain functions and making the brain more agile in responding to actions.
Establish baby's sense of security and trust in the new environment, and cultivate self-confidence and adaptability.
Babies who grow up in an unsafe environment mostly lack tact and emotional expression ability in communication with others. Therefore, the most important thing for infants to develop their intelligence is to eliminate the insecurity caused by environmental changes. Baby swimming recreates the amniotic fluid environment of the uterus, making the baby float in weightless water, and gradually feeling the safety and happiness of freely stretching his limbs in the new environment, thus helping the baby to adapt to different internal and external environments and build up self-confidence and adaptability.
Improve the sensitivity of baby sensory cells and the coordination of the body.
When a baby swims, under the combined action of various external factors, such as water temperature, hydrostatic pressure, buoyancy, water wave impact, etc., it causes a series of benign reactions of the baby's whole body skin and joints, including the nervous system and endocrine system, strengthens the stimulation of the baby's various sensory systems, and promotes the rapid transmission of comprehensive information such as kinesthetic, taste, hearing, touch and balance, thus improving the reaction force and promoting the coordinated completion of various actions by various organs.
Improve spatial imagination, reasoning ability and mathematical ability
Studies have shown that music can not only stimulate the development of hearing, but also stimulate the development of brain forelimbs, thus promoting the communication between the two hemispheres of the brain and accelerating the areas in the brain that are responsible for and deal with advanced intellectual activities such as space, reasoning, language, learning and memory. Jiahe education music is based on this, combining the famous Chinese and foreign ancient and modern songs selected by baby experts and music experts into a CD, which can not only make baby feel comfortable.
Promote food digestion and absorption, and reduce bad sleep habits.
When the baby swims, the constant movement of the body and the impact of water waves make the baby feel comfortable and relaxed, and the baby's insulin level increases obviously, thus increasing the peristalsis of the stomach and helping the digestion and absorption of food, thus increasing the appetite and absorbing nutrition more comprehensively. In addition, swimming consumes a part of physical strength, so the baby sleeps better after swimming, which is conducive to the establishment of regular sleep.
Promote height and weight gain
Because of the buoyancy of water, babies can easily slide their arms, stretch their legs and twist their waists in the water, so as to promote nutrients and oxygen in the blood to be transported to bones and muscle tissues more quickly, promote the increase of growth hormone levels in the body, and accelerate the growth of babies.
When the baby is doing unconscious whole-body exercise, his arms automatically paddle, just like chest expansion exercise, which can deepen breathing, increase vital capacity, promote blood circulation, accelerate metabolism, enhance myocardial contraction rate, and play a role in strengthening the body and improving immunity.
Generally speaking, baby swimming has advantages and disadvantages, but the key is to see what kind of mentality parents have. It can be said that as long as your method is correct, baby swimming will also be of great help to children's life-long growth, which can make children's physical coordination ability more secure.
