Freestyle (swimming)
Freestyle is a category of swimming competition, defined by the rules of the International Swimming Federation (FINA), in which competitors are subject to a few limited restrictions on their swimming stroke. Freestyle races are the most common of all swimming competitions, with distances beginning with 50 meters (50 yards) and reaching 1500 meters (1650 yards), also known as the mile. The term 'freestyle stroke' is sometimes used as a synonym for ' front crawl', as front crawl is the fastest surface swimming stroke. It is now the most common stroke used in freestyle competitions. The first Olympics held open water swimming events, but after a few Olympics, closed water swimming was introduced. The front crawl or freestyle was the first event that was introduced. Technique Freestyle swimming implies the use of legs and arms for competitive swimming, except in the case of the individual medley or medley relay events. The front crawl is most commonly chosen by swimmers, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

False Start
In sports, a false start is a disallowed start, usually due to a movement by a participant before (or in some cases after) being signaled or otherwise permitted by the rules to start. Depending on the sport and the event, a false start can result in a penalty against the athlete's or team's field position, a warning that a subsequent false start will result in disqualification, or immediate disqualification of the athlete from further competition. False starts are common in racing sports (such as swimming, track, sprinting, and motor sports), where differences are made by fractions of a second and where anxiety to get the best start plays a role in the athletes' behavior. A race that is started without a false start is referred to as a ''fair start'' or ''clean start''. In sports Association Football (soccer) Football games cannot be restarted unless certain conditions are met. For example, both teams need to be in their own half of the field for the start of the game or res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relay Race
A relay race is a racing competition where members of a team take turns completing parts of Race track, racecourse or performing a certain action. Relay races take the form of professional races and amateur games. Relay races are common in running, orienteering, swimming (sport), swimming, cross-country skiing (sport), cross-country skiing, biathlon, or ice skating (usually with a baton in the fist). In the Olympic Games, there are several types of relay races that are part of track and field. Relay race, also called Relay, a track-and-field sport consisting of a set number of stages (legs), usually four, each leg run by a different member of a team. The runner finishing one leg is usually required to pass the next runner a stick-like object known as a "baton" while both are running in a marked exchange zone. In most relays, team members cover equal distances: Olympic events for both men and women are the 400-metre (4 × 100-metre) and 1,600-metre (4 × 400-metre) relays. Some non ...

Fish Kick
The fish kick is a method of kicking while swimming, generally used underwater. It was pioneered by the American Misty Hyman and has been cited as possibly the fastest stroke for humans. Procedure and effectiveness Fish kicking is a form of undulation-based kicking, which is movement of the legs, together, forward and back in a cyclical pattern. The result of such a kick has been described as comparable to a pump, which pushes the swimmer forward. The most common form of this is known as "dolphin kick", which involves moving legs up and down (towards the top and bottom of a pool). The fish kick is essentially performing the dolphin kick sideways. The legs go left and right in a wave motion. This may have the beneficial effect of pushing water sideways, where it is not impeded, rather than the dolphin kick, which sees the water stopped by the top and bottom of the pool. The kick is sometimes cited as the fastest way to swim. An article published by ''Slate'' described it as th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Swimming
Swimming was part of the first modern Olympic games in 1896 in Athens. In 1908, the world swimming association, Fédération Internationale de Natation (FINA), was formed. Ancient times 10,000-year-old rock paintings of people swimming were found in the Cave of Swimmers near Wadi Sura in southwestern Egypt. These pictures seem to show breaststroke or doggy paddle, although it is also possible that the movements have a ritual meaning unrelated to swimming. An Egyptian clay seal dated between 9000 BC and 4000 BC shows four people who are believed to be swimming a variant of the front crawl. More references to swimming are found in the Babylonian and Assyrian wall drawings, depicting a variant of the breaststroke. The most famous drawings were found in the Kebir desert and are estimated to be from around 4000 BC. The Nagoda bas-relief also shows swimmers inside of men dating back from 3000 BC. The Indian palace Mohenjo Daro from 2800 BC contains a swimming pool sized 12 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flip Turn
A tumble turn or flip turn is one of the turns in swimming, used to reverse the direction in which the person is swimming. It is done when the swimmer reaches the end of the swimming pool but still has one or more lengths to swim. The technique's development is credited, by the International Swimming Hall of Fame, to Al Vande Weghe at the AAU Nationals in 1934. Previously this entry erroneously credited the invention of the flip turn to University of Texas swim coach Tex Robertson while he was training Adolph Kiefer for the 1936 Olympics. Flip turns are usually only used during freestyle and backstroke races. In butterfly and breaststroke races, regulations require swimmers to touch the end of the pool with both hands simultaneously before turning back for another length. While they legally can flip turn during butterfly and breaststroke races, it is more common to turn left or right to begin the next lap. This style of turning is called an open turn. If the event is medley s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1936 Summer Olympics
The 1936 Summer Olympics (German: ''Olympische Sommerspiele 1936''), officially known as the Games of the XI Olympiad (German: ''Spiele der XI. Olympiade'') and commonly known as Berlin 1936 or the Nazi Olympics, were an international multi-sport event held from 1 to 16 August 1936 in Berlin, Germany. Berlin won the bid to host the Games over Barcelona at the 29th IOC Session on 26 April 1931. The 1936 Games marked the second and most recent time the International Olympic Committee gathered to vote in a city that was bidding to host those Games. Later rule modifications forbade cities hosting the bid vote from being awarded the games. To outdo the 1932 Los Angeles Games, Reich Führer Adolf Hitler had a new 100,000-seat track and field stadium built, as well as six gymnasiums and other smaller arenas. The Games were the first to be televised, with radio broadcasts reaching 41 countries.Rader, Benjamin G. "American Sports: From the Age of Folk Games to the Age of Televised Spo ...

1924 Summer Olympics
The 1924 Summer Olympics (french: Jeux olympiques d'été de 1924), officially the Games of the VIII Olympiad (french: Jeux de la VIIIe olympiade) and also known as Paris 1924, were an international multi-sport event held in Paris, France. The opening ceremony was held on 5 July, but some competitions had already started on 4 May. The Games were the second to be hosted by Paris (after 1900), making it the first city to host the Olympics twice. The selection process for the 1924 Summer Olympics consisted of six bids, and Paris was selected ahead of Amsterdam, Barcelona, Los Angeles, Prague, and Rome. The selection was made at the 20th IOC Session in Lausanne in 1921. The cost of these Games was estimated to be 10,000,000 F. With total receipts at 5,496,610F, the Olympics resulted in a hefty loss despite crowds that reached up to 60,000 in number daily. The United States won the most gold and overall medals, having 229 athletes competing compared to France's 401. Highlights * The ...

Drag (physics)
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and the squared velocity for high speed flow, where the distinction between low and high speed is measured by the Reynolds number. Even though the ultimate cause of drag is viscous friction, turbulent drag is independent of viscosity. Drag forces always tend to decrease fluid velocity relative to the solid object in the fluid's path. Examples Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to the di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stockholm
Stockholm () is the Capital city, capital and List of urban areas in Sweden by population, largest city of Sweden as well as the List of urban areas in the Nordic countries, largest urban area in Scandinavia.
