Swimming, swimming , competition in the four types of swimming (free swimming, back crawl, butterfly, breaststroke), medley, apparatus and fin swimming , synchronous swimming as well as jumping , water polo and various underwater sports, eg underwater rugby with lifeguard training near me.
Competitive conditions
Swimming competitions are held in 25- and 50-m pools. The turn with subsequent starting makes swimming a little faster in the 25-m pool. The World Cup takes place on the 25- and 50-m track, the Olympics on the 50-m track. The basin is divided into ten lanes, which are separated by floating, wave-breaking path ropes; the two outermost orbits are not used in competition because the water resistance at backlash of waves is greater here.
Below each course there is a dark line on the bottom of the pool, which stops 2 m from the end wall with a transverse line to indicate the distance to the turn. For the same purpose in back crawl, flags are hoisted across the pool 5 m from the end wall; also on the end wall markings have been made. The water temperature should be 25-27 ° C.
Jumping takes place from a stool except in back crawl, where the swimmer starts in the water with his back to the direction of swimming. The starting stool has a rough surface with a slope of max. 10% towards the water. In the starting stool there are handles that the back swimmer can hold on to. The second time the jump starts, the swimmer is disqualified. The times are recorded by touching a plate with electronic recording equipment or with a stopwatch with lifeguard training near me.
Disciplines
Common to the four types of swimming is that the arms perform S-like movements and thus pull in / push on water that the hand has not already set in motion, which gives the most efficient propulsion. When the hands are angled, the arm movements are reminiscent of a ship’s propeller.
In free swimming , the swimmer can decide for himself how the propulsion takes place. Most often, crawl is swum, which is fastest because the constant speed and completely horizontal posture creates the least possible resistance in the water, while the swimmer can create the optimal propulsion. The turn takes place most quickly with a salt turn (a flask); a part of the body (feet) should touch the end wall. It is allowed to swim the first 15 m below the water surface, where the resistance is less than in the water surface.
In back crawl , the supine position must be maintained throughout the race, except in the turn, where it is allowed in the last roof to turn around the abdomen and make a somersault, where the feet touch the end wall. Also in back crawl, the first 15 m can be covered below the water surface.
In butterfly , the arms must be moved simultaneously throughout the movement and forward over the water. The swimming must take place breast-lying. The legs move up and down simultaneously. Both hands should touch the wall in turns. The first 15 m can be covered below the water surface.
Breaststroke should be performed on the chest, the hands should not be moved behind the hip line, and the arms should be advanced partially in the water. The incomplete armrest and water resistance in the feed make breaststroke the slowest of the four species. MH. the swimming rules differentiate breaststroke from the other three, in that part of the body in these types of swimming must be above the water throughout the race, while the whole body in breaststroke may be underwater; however, the head must break the surface of each roof.
In addition to the four swimming species, medley competitions are held , which form a mixture of all four swimming species. Individual swim in the following order: butterfly, back crawl, breaststroke, free swim, while the order in team cap is back crawl, breaststroke, butterfly and free swim.
At the World Cup and Olympics, competitions are held at distances between 50 and 1500 m (men, women and teams). In addition, competitions for swimming in open water of 5 and 25 km (men, women, teams) are held.
History
Swimming skills are evidence of thousands of years before the birth of Christ. Swimming figures are seen on Assyrian and Egyptian reliefs and papyrus scrolls. In ancient Greece and Rome, swimming was an important skill for warriors who had to fight on the lake.
In the Nordic countries, the Vikings were known for their swimming skills, and sources report swimming lessons in the Middle Ages, where an inflated pig bladder served as a buoyancy aid.
The first organized swimming competitions took place in England in the 1830s, where swimming pools were built in London. The International Swimming Federation, Fédération International de Natation Amateur (FINA), was founded in 1908.
At the beginning of the competitive swimming, a form of breaststroke was performed on the side with a sling leg. Crawl was developed by moving one arm forward over the water.
It was not until around 1900 that a distinction was made between breaststroke and crawl. On the back, “reverse breaststroke” was performed, ie. backstroke with synchronous arm extension. Simultaneously with the development of crawl, backstroke swimming with asynchronous arm cycle (back crawl) was also developed.
By 1953, breaststroke had evolved with arm-raising over the water, leading to this species of swim being excreted as a butterfly; at the same time, the butterfly leg kick was transformed into a dolphin leg kick, which is similar to the crawl leg movement, albeit with synchronous movements.
International competitions
Swimming was on the program at the first Olympic Games in 1896 (though only for men, women from 1912). Butterfly came on the Olympic program from 1956, and medley from 1960.
Annual European Championships (EC) in short track (25 m) have been held since 1926 (women since 1927). From 1981, the European Championships are also held on long distance (50 m) every other year in odd years. However, from the year 2000 onwards, it is changed so that it is held every other year for even years.
World Championships on the long track have been held since 1973, every four years from 1978. Since 1993, the World Cup has also been held on the short track. From the year 2000 onwards, the World Cup will be held every other year on the short track and from the year 2001 every other year on the long track.
Danish swimming
With the School Act of 1814, swimming was introduced on the school schedule. However, real swimming lessons have only occurred in a few places where there has been access to open water or to the bathing establishments that were built around the country and formed the framework for teaching and training right up to the 1920s and 1930s, when the first swimming pools were built.
Available in the early 2000-t. almost 300 swimming pools in Denmark, and approx. 75% of the municipal primary and lower secondary schools offer swimming lessons during the school year.
Being able to swim is vital – especially in Denmark.
Can not swim? Then it’s not too late for you to learn it! With coastlines around all of Denmark, there is enough water to drown in. And it unfortunately happens to far too many every year – throughout Europe, approx. 37,000 kroner , which is not so little again. And that’s exactly why swimming is so mega important!
