Swimming has long ceased to be just a sport. Now, this is cardio loading, physical education, and hardening, and just relaxation.
Engaged in swimming, you positively influence your psycho-emotional state, strengthen individual organs and health in general. With regular exercises in this sport, metabolism improves, blood flow speeds up, blood vessels strengthen, all muscle groups develop harmoniously, and the figure acquires harmony. The total volume of blood circulating throughout the body becomes larger, venous congestion decreases, and the process of oxygen transport to all tissues and organs is accelerated.
An established medical fact is that regular swimming classes prevent a large number of diseases, especially colds, and maintain the required level of activity and performance.
Basic swimming styles will be described below:
When swimming the breaststroke, the athlete, sitting on his stomach, first makes an asynchronous movement of his hands forward, and then makes a stroke. At this time, the legs bent at the knees perform a push. The breaststroke is characterized by a low speed of movement, the greatest complexity of development, and low energy consumption, and low noise.
Butterfly translated as a butterfly and got its name because of some similarities with butterfly flying. But it is much more similar to the way a dolphin swims, so in ordinary people, this style of swimming is called “swim dolphin”.
Butterfly quite a long time attributed to one of the varieties of brass. In this style, the swimmer, also on his stomach, make his hands stroking along a specific path, which results in lifting the athlete’s body above the water. Legs at this time move in waves.
The butterfly stroke is rated as the most difficult to learn, energy-consuming, and heavy style. So swimmers who specialize in butterfly stroke are most physically developed. They mainly have a shoulder girdle. Butterfly in speed is second only to the rabbit.
In ordinary people, this style of swimming was given the name free. It is the fastest style, and in terms of energy costs, it is located between butterfly and breaststroke. Swimming in the described manner, the athlete takes turns doing a row with his hands slightly bent, legs, while, according to the principle of scissors, they move alternately up and down.
Crawl style on the back
The athlete, being on his back, alternately makes strokes with his hands without bending them; at this time, the legs move alternately up and down. In terms of speed of movement, the style is inferior to the rabbit and butterfly, ahead of only the breaststroke. The crawl on the back is different in that the face is always above the water, so there is no need to exhale into the water.
Water polo players must be able to swim well on their backs. When playing water polo, it’s on the end that the teams return to their gates.
Types of swimming
If we talk about the types of swimming, the following are distinguished: a marathon (moving long distances, carried out in an open reservoir), a combined relay race and complex swimming (an athlete or a team swims a predetermined distance using various styles), scuba diving, diving at a distance, swimming with obstacles, in flippers and even in clothes.
Also interesting types of swimming ninja and samurai. These species involve the movement of swimmers in water in full combat ammunition along with weapons that did not sink into the water, and sometimes were used for their intended purpose – in this case, only legs were used to move. In particular, wars learned to swim along with heavy objects of considerable weight, such as signal flags or shells.
