swimming

History of swimming.

Competitive swimming in Europe started around 1800, mostly using the breaststroke. In 1873 John Arthr Trudgen introduced the trudgen to Western swimming competitions, after copying the front crawl used by Native Americans. Due to a British disregard for splashing, Trudgen employed a scissor kick instead of the front crawl's flutter kick. Swimming was part of the first modern Olympic games in 1896 in Athens. In 1902 Richard Cavill introduced the front crawl to the Western world. In 1908, the world swimming association, Fédération Internationale de Natation (FINA), was formed. The butterfly stroke was developed in the 1930s and was at first a breaststroke variant, until it was accepted as a separate style in 1952. In 1964, Lillian Bonnell won the award for being the first woman to participate in a swimming competition and because of her now millions of women participate every year.

[edit] Competition

The goal of competitive swimming is usually to have the fastest time to complete a given distance. Competitive swimming became popular in the nineteenth century.[1]
Swimming is an event at the Summer Olympic Games, where male and female athletes compete in 13 of the recognized events each. Olympic events are held in a 50 meter pool (long course). There are 37 officially recognized individual swimming events – 18 male events and 19 female events, however the International Olympic Committee only recognizes 35 of them – 17 male and 18 female. The international governing body for competitive swimming is the Fédération Internationale de Natation ("International Swimming Federation") better known as FINA..

[edit] Competition pools

Most swimming sport events are held in special competition swimming pools, which are either long course pools such as those used in the Olympic Games (50 m) or short course pools such as those used in the FINA World Swimming Championships (25 m) (25 yards or 25 m). Competition pools have starting blocks from which the competitor can dive in, and possibly also touch-sensitive pads to electronically record the swimming time of each competitor.

[edit] Seasons

Club swimming in the US has two major seasons. During the short-course season, swimmers swim in 25 yard pools. This season lasts from September to the end of March. The long-course season is swum in 50 meter Olympic pools and lasts from April to the end of August.

[edit] Officials

There are several types of officials:[2]
Referee: The referee has full control and authority over all officials. The referee will enforce all rules and decisions of FINA and shall decide all questions relating to the actual conduct of the meet, and event or the competition, the final settlement of which is not otherwise covered by the rules. The referee takes overall responsibility for running the race and makes the final decisions as to who wins the competition.
Starter: The starter has full control of the swimmers from the time the referee turns the swimmers over to him/her until the race commences. A starter sends the swimmers off the blocks and may call a false start if a swimmer leaves the block before the starter sends them.
Clerk of Course: The clerk of course assembles swimmers prior to each event.
Timekeepers: There are three (3) timekeepers for each lane. Each timekeeper takes the time of the swimmers in the lane assigned to him/her. Unless a video backup system is used, it may be necessary to use the full complement of timekeepers even when Automatic Officiating Equipment is used. A chief timekeeper assigns the seating positions for all timekeepers and the lanes for which they are responsible. The chief timekeeper collects from the timekeepers in each lane a card showing the times recorded and, if necessary, inspect their watches.
Inspectors of Turns: One inspector of turns is assigned to each lane at each end of the pool. Each inspector of turns ensures that swimmers comply with the relevant rules for turning as well as the relevant rules for start and finish of the race. Inspectors of turns shall report any violation on signed cards detailing the event, lane number, and the infringement delivered to the chief inspector of turns who will immediately convey the report to the referee.
Judges of Stroke: Judges of stroke are located on each side of the pool. They ensure that the rules related to the style of swimming designated for the event are being observed, and observe the turns and the finishes to assist the inspectors of turns.
Finish Judges Finish Judges determine the order of finish and make sure the swimmers finish in accordance with the rules (two hands simultaneously for breaststroke and butterfly, on the back for backstroke, etc.)
If an official catches a swimmer breaking a rule concerning the stroke he or she is swimming, that swimmer is said to be disqualified (commonly referred to as a "DQ") and the swim is not considered valid. The referee can disqualify any swimmer for any violation of the rules that he personally observes. The referee may also disqualify any swimmer for any violation reported to him by other authorised officials. All disqualifications are subject to the decision of the referee.

[edit] Meet Setup

A meet consists of a number of events classified by age, gender, distance, and stroke. For example, Event 1: Girls 8&U 25 fly. Each event has a certain amount of heats. A heat is a group of people who swim at the same time, one person per lane, yet compete against all entries in that event. Most meets do one stroke at one time. A heat sheet tells a swimmer what they will swim and in what heat and lane. A psych sheet tells the entry position of the swimmer before the start of the meet. Larger meets, which are not national or international competitions, typically cover a three day period, usually Friday, Saturday, and Sunday. Fridays are typically the distance events: 400 free, 800 free, 1000 free, 1500 free, 1650 free, and the 400 IM. Saturdays consist half of the events and, most likely, free relays. Sundays consist of the remainder of the events and the other relays. In typical meets, swimmers are placed after swimming once in their heat, timed finals. In championship meets (international, national, state, regionals, district, and collegiate) and some other meets, the swimmers compete in preliminaries, sometimes semi-finals, and are placed after finals. Sometimes swimmers can enter time trials at a meet, to obtain new official times, but the results of time trials are not included in the official placing of the particular event at the meet.
