What is water is something other than the cradle of life. Do not forget about it and visit the pool as often as possible. Water is much denser than air and it follows that while moving in water it will be more difficult for us to move and therefore we will lose more calories.
Our conversation today will focus on the benefits of swimming on the human body and what styles of swimming are.
Swimming is movement in the water, overcoming distances and completing a cycle of classes. And don’t confuse it with swimming. Bathing, of course, is also useful for general tone and good mood, but swimming should not be compared with swimming.
A person engaged in swimming improves sleep, increases attention, improves memory.
Since swimming is considered one of the safest sports, it is recommended to practice it at any age.
The effect of swimming on the cardiovascular system:
Swimming in general has a positive effect on the cardiovascular system.
For a person who swims regularly, the pressure normalizes (very useful for people with hypertension), the metabolism works faster, that is, the body burns calories faster. According to the observation of doctors, the pulse drops below 60 beats per minute and, most importantly, the heart works smoothly and economically.
The effect of swimming on the nervous system:
Swimming for the nervous system is the most powerful influencing factor, in which the processes of excitation and inhibition in the central nervous system are balanced and the blood supply to the brain improves. During swimming, we noticeably calm down and relieve tension, due to the fact that the water gently massages the nerve endings located on the surface of the skin.
The effect of swimming on breathing:
At the moment when we swim, our chest increases mobility and due to this, ventilation of the lungs increases. Not a small role here is played by the fact that when we are actively engaged in swimming in our lungs, those areas that are not active in everyday life are activated. And this has a very good effect on health, so that we become less susceptible to any lung diseases.

For people with low oxygen content in tissues, it is very useful to practice diving with air retention. So, as during diving with air retention, resistance to hypoxia (oxygen starvation) is developed.
The effect of swimming on the joints:
When we immersed in water, our musculoskeletal system is in a state of relaxation, from the fact that the pressure of the entire body weight decreases. So, people with problems in the spine and joints should and should visit swimming pools in order to improve their health and increase the motor activity of our joints in general.
And so, swimming is useful at any age, even for expectant mothers. Because the expectant mother, immersed in water, immediately feels the relaxation of all muscles, the load on the spine is relieved and it is an excellent prevention from edema and varicose veins. It is especially useful when the deadlines for expectant mothers are just around the corner.

Swimming styles:
Play swimming.

The gaming types of swimming include all any outdoor games that can be used in the aquatic environment. During the games, we have a great rise in positive emotions, coordination of movement develops and activity increases. Widespread use in various water holidays and health camps, was the use of one of these games called water polo.
Water polo is a sports team game with a ball on the water, the goal of the game is to throw the ball into the opponent’s goal as many times as possible and not let the ball into your own goal. The game takes place in a pool measuring 30×20 meters, the depth should not be less than 180 cm. The bottom of the water field is placed with markings, they are also indicated by floats of different colors along the border of the pool. Teams participate in the game 2, 7 players in each, one of them is the goalkeeper. Goal size: 90 cm high, 3 meters wide. Only the goalkeeper has the right to take the ball with both hands. The water polo ball should not absorb water, the color of the ball is usually yellow, the circumference is from 68 to 71 cm, the weight is from 400 to 450 grams (3 sizes in total: for children, juniors and adults). There are only four periods in the game, each period lasts for 8 minutes. The maximum possession time for a team must not exceed 30 seconds.

Sports swimming.

These are various kinds of competitions that are held in a pool 50 or 25 meters long at a distance of 50 to 1500 meters. There are also swims in open water, but these distances are for more experienced and enduring athletes, the length of the distance for which is (5, 10, 25 km). The distance is overcome strictly according to the regulated rules of the competition.
Swimming sports are butterfly, breaststroke, front crawl and front crawl.
Butterfly (dolphin) is considered one of the most technically difficult and difficult swimming style. The swimmer swims on his stomach and makes symmetrical, powerful movements with his arms that push the person out of the water, and the swimmer’s legs and pelvis perform undulating movements.
Breaststroke is the most popular and ancient style of swimming. This style is calm and does not exhaust forces, because the hands are constantly in the water, because of this, the speed when swimming is not high.

The execution technique looks like this, the body of the swimmer is straightened, the arms are extended forward and the head is submerged under water. The next action is to turn the palms outward and push the water back. The arms end their movement at shoulder level, after which the arms must be bent at the elbows in front of you and extended to the initial position forward (all these movements are performed so that the arms are under water). At the moment when the arms perform their movement, the legs are pulled up to the body. And we must not forget that the feet are slightly wider than the knees. At the time when the arms are stretched forward, it is necessary to make a push with the legs so that the body slides on the surface of the water. Before you push with your feet, take a breath, raise your head above the water.
The front crawl is the fastest swimming style, performed on an alternating and symmetrical movement of the arms and legs, six alternate kicks and inhalation and exhalation. The head is lowered into the water, the water level is approximately on the line of the forehead. At the moment when we inhale (we inhale through the mouth), the head should be turned towards the hand that is currently sweeping over the water, and exhalation is made through the nose and mouth at the same time, during the entire interval until the next breath.
The crawl on the back is similar to the inverted front crawl – the swimmer also performs alternate strokes with his hands and at the same time makes alternate kicks in a vertical plane. The athlete’s face is above the water almost all the time (with the exception of the start and turns), this style of swimming is very convenient for moving through the water.
