Swimming is an individual or team sport that requires the use of arms and legs to move the body through the water. This sport takes place in swimming pools or open waters (for example, at sea or lake). Competitive swimming is one of the most popular Olympic sports, with various events such as butterfly distance, backstroke, breaststroke, freestyle and individual with lifeguard class.
In addition to these individual events, four swimmers can take part in any freestyle or mixed relay. The relay set consists of four swimmers, each of whom will swim differently. The order for the mixed relay is: back, chest, butterfly and free.
In competition, there are different regulations in the area of acceptable form for each individual. There are also regulations on what types of swimwear, hats, jewelry and injury are allowed at competitions.
The goal of high-level competitive swimming is to break a personal or world record, with competitors competing in every given event. In swimming towards, the curability should create less resistance in order to get the maximum speed.
However, some professional swimmers who do not have a national or world ranking are considered the best in terms of their technical skills. Typically, an athlete goes through a training cycle in which the body is overloaded with work at the beginning and middle of segments of the cycle. The workload is reduced in the final stage as the swimmer approaches the competition.
In open water swimming, there are also 5 km, 10 km and 25 km for men and women. However, only the 10 km event is included in the Olympic schedule, once for both men and women.
In competitive swimming, four main styles are identified. These are relatively stable over the last 30-40 years with minor improvements.
They are: Butterfly, Coat of Arms, Chest and others.
Competition, only one of these styles can be used except in the case of mixed, or IM, which consists of all four. In the latter case, the swimmers swim equal distances on a butterfly, then backstroke, breaststroke, and finally freestyle.
At the Olympics, this event swims in two distances – 200 and 400 meters. Some short competitions of course also include 100m IM – especially for junior or younger swimmers (usually under 14) who are in a swimming club, or masters of swimming (over 18).
Since 1990, the most drastic change in swimming has been the addition of an underwater dolphin blow. This is used to increase the start and end speed in all styles.
