1. swimming can enhance myocardial function
When people exercise in the water, all organs are involved in it, with a lot of energy and blood circulation accelerated to provide more nutrients with sports organs.The acceleration of blood speed will increase the load of the heart, which will speed up the frequency of beating, and the contraction is strong and powerful.People who swim frequently have excellent heart function.The effect of water during swimming makes the blood of the limbs easily return to the heart and speed up the heart rate.Long -term swimming will significantly increase the heart movement, the contraction is strong, the thickness of the vascular wall increases elasticity, and the amount of blood output per combination increases.Therefore, swimming can exercise a strong heart.
2. swimming can enhance resistance
The water temperature of the swimming pool is often 26 degrees to 28 degrees, soaking in water is fast and high, and energy consumes great energy.In order to replenish the calories emitted by the body as soon as possible, for the need for hot and cold balance, the nervous system quickly responded to accelerate the metabolism of the human body, enhance the human body's ability to adapt to the outside world, and resist the cold.Those who often participate in winter swimming, due to the improvement of the body temperature regulation function, are not easy to hurt the wind, it can also improve the endocrine function of the human body, increase the pituitary function, and increase the resistance and immunity to the disease.
When swimming, the body is immersed in water directly. The water is not only resistant to resistance, but also the heat conduction performance is very good. The heat dissipation speed is fast, so it consumes a lot of calories.It's like a ripe egg, the cooling speed in the air is far less fast in cold water. Experiments have proved that the calories consumed by Running in the standard swimming pool for 20 minutes are equivalent to the same speed on the land for 1 hour on land.The calories consumed in 14 degrees of water for 1 minute are as high as 100 kcal, which is equivalent to the calories emitted in the same temperature air.It can be seen that exercising in water will make many people who want to lose weight and achieve more effort. Therefore, swimming is one of the most effective movements to maintain body figure.
4. swimming can improve the flexibility of the body
When swimming, people usually use the water's buoyancy to lie down or lying on the water in the water.Due to the reduction of the impact on the bones during the ground motion, the chance of the bones is reduced, and the Bone joint is not easy to deform.The resistance of water can increase human movement intensity, but this intensity is different from the equipment training on the land. It is very soft. The strength of the training is easily controlled in the oxygen field.The muscles can make the whole body Smooth and beautiful.
5. swimming can help relieve stress and depression
Endorphin is a kind of good hormone that can improve people's emotions. swimming can effectively stimulate the secretion of endorphins and help people alleviate the pressure of daily work and life. In addition, swimming can make people fully relax themselves like yogaIf the body is combined with a regular deep breathing, the effect will be better.At the same time, swimming can calm people, eliminate external interference, and become more focused, which naturally reduces people's tension and depression.Related research confirms that swimming can also help restore the brain function that is damaged due to stress through a process called hippocampus regeneration.So, if you don't feel in your state one day, you may wish to change to the Swimsuit and jump to the pool to release your emotions!
When people swim, the water of water, sweat, and fat glands in water plays a good massage effect, promotes blood circulation, and makes the Skin Smooth and elastic.In addition, during the water, it greatly reduces the stimulation of the Skin in the sweat.
People can strengthen the strength of the whole body through swimming.Running can improve people's legs, and swimming requires muscle coordination force in all parts of the whole body, so it can exercise the muscles of the whole body.Leg -kicking back, pulling water on both arms, stretching back, tightening abdomen to increase the strength of the legs and maintain the stability of the hip. The basic movements of these swimming make every piece of muscles of the whole body HIGH.Avoid the effect of pit fathers such as muscle unevenness that may cause equipment exercise.
Once upon a time, many people sneered at the view of "swimming can improve Bone quality". After all, it seems that only weight exercises can achieve this goal. However, a study published in the "Applied Physiology" magazine supports this view.Because there are some moral disputes on the human body's Bone inspection directly, the researchers then used mice as a research object and divided them into three groups: the Running group, swimming group, and control group (non -exercise).Studies have shown that Running can best increase Bone density, and compared with the control group, the swimming group does better, whether in the Bone density or the increase in the weight of the thigh Bone.It can be seen that if you want your bones to be healthier, swim!
9. swimming can reduce inflammation risk
As we all know, swimming can help enhance myocardial function and improve cardiovascular health. Related research further confirms that aerobic exercises such as swimming can help reduce inflammation risks and prevent diseases such as cardiology caused by this.In addition, reducing the inflammation risk in the entire system can also alleviate the deterioration of many other diseases and benefit a lot.
10. swimming can relieve sporty asthma
There is no more sadness than dyspnea during exercise! Compared with the dry gym or Outdoor gym in air, people can breathe wet air and improve respiratory function during swimming.Studies have confirmed that swimming can not only relieve the symptoms of asthma, but also fundamentally improve the health of the lungs.The most typical example is the Korean swimming player Park Tae -hyun. He suffered from asthma when he was a child. Then his parents asked him to practice swimming to help relieve the symptoms. As a result, not only the asthma disappeared, but also became the Olympic champion. It was really good!
11. swimming can make people smarter
Can exercise improve people's mental state, but can swimming really make people smarter? Researchers from Australia have studied a group of children participating in swimming training courses, and with another group of children who did not study swimming,Group.The results show that children who often swim often have faster and better in terms of grasping language, learning cycling, building self -confidence, and physical development.In addition, because swimming needs to repeatedly calculate the distance of the tour, people who swim frequently are also excellent in terms of arithmetic!
12. swimming can prolong life
Everyone knows that exercise can improve health and extend life, but research has further confirmed that swimming has done the best in these two aspects.Researchers at the University of Southern California tracked and observed for 32 years of men aged 20-90 years old. The results showed that men with swimming habits are lower than men who are Running, walking or not exercising often in terms of mortality rates.Nearly half.It can be seen that if you want to live long, swimming is definitely a good dose!
Disadvantages of swimming
1. Suitable to suffer from infectious diseases
Because there are many crowds in the swimming pool, there will also be a large number of infectious disease bacteria in the water. If the immunity is not good, it will be easily infected if it stays in the water for too long.
2. Triggement cramps
Time swimming will cause the muscle to overwork and cramps. In severe cases, drowning may occur, which is also a major disadvantage of swimming.
Of course, as long as we swim rationally, the benefits it brings to us is more disadvantaged.Therefore, pay attention to various possible problems when swimming.
swimming exercise is appropriate several times a week
Professional swimmer is a high -intensity training every day, only on Sunday.The general non-professional is 2-3 times a week.If you want to lose weight, you have to ensure the amount of exercise. For example, you are almost one and a half hours at a time.
1. Find the location of the dessert first
That position is that after you have the balancing of the back, the body is then practicing the balance, kicking the water softly, always keeping the feet in the water marks behind you. When you relax and balance, turn your head up and look up.The head is exposed, and the hiding head is only the face on the water, keep the head and the spine straight, and try different rotation angles until you find you feel the most comfortable position, that is, desserts.Some people's desserts are 90 degrees, while others are particularly thin. The balance is the best when turning a certain angle on the back.
After practicing three times to change your arm, you can simply and calmly enter the whole swimming state.Maintaining a consistent time to change the arm. This rhythm is: look down, change the arm, change the arm, change the arm, change the arm, change the air, look down, then change the arm, change the arm, change the arm, go directly to the dessert position after three timesEssenceAfter the rhythm of the arm changing is skilled, the center of gravity changes also has the rhythm, and the center of gravity is converted from one to the other.And if you try to extend your body line, you can turn the body smoothly like a fish, forming a beautiful and Smooth swimming style.
2. Step in the water calmly
The more traditional method of stepping on the water: cycling feet, two feet like a bicycle, turn alternately to step on the water, which is more tired, because it is constantly stepping on; a flexible way: the breaststroke feet, the same as the breaststroke, the two feet are put away at the same time at the same timePassing out downward, do not need to pinch your legs after kicking, and put it away (the frequency of the water is better controlled).
