Road Racing World Championship Grand Prix is the premier championship ofmotorcycle road racing currently divided into three distinct classes: 125cc, 250cc and MotoGP. The first two are held with two-stroke and the last with four-stroke engines. In 2010 the 250cc was replaced by the new Moto2 600cc four-stroke class. So, after 2010 there will be one two-stroke class, 125cc, and 2 four-stroke classes: Moto2 and MotoGP. Grand Prix motorcycles are purpose-built racing machines that are neither available for purchase by the general public nor can be ridden legally on public roads. This contrasts with the various production categories of racing, such as the Superbike World Championship, that feature modified versions of road-going motorcycles available to the public.
A Road Racing World Championship Grand Prix was first organized by the Fédération Internationale de Motocyclisme (FIM) in 1949. The commercial rights are owned by Dorna Sports. Teams are represented by the International Road Racing Teams Association (IRTA) and manufacturers by the Motorcycle Sport Manufacturers Association (MSMA). Rules and changes to regulations are decided between the four entities, with Dorna casting a tie-breaking vote. In cases of technical modifications, the MSMA can unilaterally enact or veto changes by unanimous vote among its members.[1] These 4 entities compose the Grand Prix Commission.

skateboarding
Skateboarding is the act of riding and performing tricks using a skateboard. A person who skateboards is most often referred to as a skateboarder, or colloquially within the skateboarding community, a skater.
Skateboarding can be a recreational activity, an artform, a job, or a method of transportation.Skateboarding has been shaped and influenced by many skateboarders throughout the years. A 2002 report by American Sports Data found that there were 18.5 million skateboarders in the world. 85 percent of skateboarders polled who had used a board in the last year were under the age of 18, and 74 percent were male.
Skateboarding is relatively modern. A key skateboarding maneuver, the ollie, was developed in the late 1970s by Alan "Ollie" Gelfand as a half-pipe maneuver. Freestyle skateboarder Rodney Mullen was the first to take it to flat ground and later invented the kickflip and its variations. [3]

wrestling(WWE)
Wrestling is an ancient martial art that uses grappling type techniques such as clinch fighting, throws and takedowns, joint locks, pins and other grappling holds. A wrestling bout is a physical competition, between two (occasionally more) competitors or sparring partners, who attempt to gain and maintain a superior position. There are a wide range of styles with varying rules with both traditional historic and modern styles. Wrestling techniques have been incorporated into other martial arts as well as military hand-to-hand combat systems.
The term wrestling is an Old English word that originated some time before 1100 A.D. It is perhaps the oldest word still in use in the English language to describe hand-to-hand combat. The Merriam-Webster online dictionary defines wrestling as "a sport or contest in which two unarmed individuals struggle hand-to-hand with each attempting to subdue or unbalance the other".

beach volleyball
Beach volleyball, or sand volleyball, is an Olympic team sport played on sand. Like other variations of volleyball, two teams, separated by a high net, try to score points against the other by grounding a ball on the other team's court. Competitive beach volleyball teams usually consist of two players, though recreational variations can contain up to six players.
Originating in Southern California and Hawaii, beach volleyball now receives worldwide popularity, even in countries without traditional beaches, like Switzerland.
Though popularized in Southern California, the first recorded beach volleyball games took place on the beaches of Waikiki in Honolulu, Hawaii at the Outrigger Canoe Club. Originally designed to give bored surfers something to do when the surf was down, the game quickly developed into more organized six-man matches. The most famous early player was legendary waterman, Duke Kahanamoku.

different swimming strokes
There are many modalities of swimming competitions, distinguished mainly by the swimming strokes that are allowed, including the following
Butterfly or fly: the course must be completed entirely in the butterfly style, in which the swimmer brings his or her arms near full extension and releases at the waist. While the swimmer's arms are at full extension the head comes up to take a breath as the arms pull down. As the swimmer releases the water past their hips, they bring their arms up and out into the recovery while the head goes back down. "Dolphin kicking" (undulating) with both feet together in sequence with two kicks per arm stroke. Usually there is a kick while the hands are at full extension and then one at the recovery when the hands are at their hips. All end walls must be touched with two hands, and the swimmer will be disqualified if his/her arms do not clear the water at the same time. Typical distances include 50, 100, 200 meters or yards. Novice swimmers may compete in 25 meter or yard butterfly races.
Backstroke or back: competitors must swim in the backstroke style, which is similar to the front crawl, except on the back. Kicking is done by alternating both feet continuously. The arms pull one at a time in a windmill motion on the side of the body. At the end walls, flip turns are permitted (the swimmer is to turn on to his/her front before performing the freestyle flip turn), and a two-hand touch is not necessary. Typical distances include 50, 100, 200 meters or yards, depending on the pool. Novice swimmers may compete in 25 meter or yard backstroke races.
Breaststroke or breast: competitors must swim in the breaststroke style, where the swimmer kicks legs out (much like a frog, but more whip like and with the knees staying closely together). The hands meanwhile scoop the water in towards the chest and are then thrust forward in front of the body just before the kick is repeated. The breath is started as the hands pull the water from full extension, the head bobs up, and then put back down as the arms thrust forward. One underwater "pull-out" is permitted for the start and after every end wall, with, in order: streamline glide, one fully extended pull, one breaststroke kick while bringing the hands back forward. This pullout is done under water without a breath. Both hands must touch the wall simultaneously at every turn like in the butterfly modality. After the 2004 Olympics in Athens, Greece, there was an adjustment made to the underwater "pull-out", allowing a single downward dolphin kick to be performed simultaneously with the arm pull. Typical distances include 50, 100, 200 meters or yards. Novice swimmers may compete in 25 meter or yard breaststroke races.
Freestyle or free: competitors are free to use any stroke they wish. Most select the front crawl, as it is both the fastest and most efficient. The front crawl is where the swimmer breathes to the side with typically one ear staying in the water, kicks by alternating both legs, and pulls with each arm moving in an alternating fashion. Flip/tumble turns are legal and are used nearly universally. Typical distances are 50, 100, 200, 400, 500, 800 and 1500 metres, as well as 50, 100, 200, 500, 1000, 1650 yards. Novice swimmers may compete in 25 meter or yard freestyle races. Freestyle may also be swam as a relay with four swimmers, in 4x50, 4x100 or 4x200 formats.
Individual medley or IM: each swimmer must complete one quarter of the full distance in each of the three competition styles (butterfly, backstroke, breaststroke) and one part in free style. Open turns are required in the switch from one style to another, but flip turns or bucket turns can be made during a backstroke and freestyle flip turn where the next stroke is the same as the previous one. Suicide turns are also allowable during the transition from backstroke to breaststroke. Each part must be completed in its style before moving on to the next style. The full distance is typically 100, 200, or 400 meters or yards. There is also a medley relay in which four swimmers each swim one of the four strokes. The relay is swam in 4x50 or 4x100 formats, and in the following order: backstroke, breaststroke, butterfly, freestyle.
At the end walls, the following turns may be permitted, depending on the modality and swimming style:
Open turn
Flip turn or tumble turn
Backwards flip turn or bucket turn

about swimming
The aquatic sport of swimming is based on the human act of swimming, that is, locomotion in water by self propulsion, with the goal of completing a given distance in the shortest amount of time. There are also swimming competitions for endurance or precedence rather than speed, such as crossing the English Channel or some other stretch of open water. Swimming is distinguished from other aquatic sports (such as diving, synchronized swimming, and water polo) that involve swimming but the goal is neither speed nor endurance.
Competitive swimming consist of four strokes: butterfly, breaststroke, freestyle (or front crawl), and backstroke. When all four strokes are done during a race, it is called medley swimming (otherwise known as the individual medley, or I.M.).

about cricket
Cricket is a bat-and-ball team sport. Many variations exist, with its most popular form played on an oval-shaped outdoor arena known as a cricket field at the centre of which is a rectangular 22-yard (20.12 m) long pitch that is the focus of the game. A game (or match) is contested between two teams of eleven players each. One team bats, and will try to score as many runs as possible while the other team bowls and fields, trying to dismiss the batsmen and thus limit the runs scored by the batting team. When the batting team has used all its remaining batsmen within the available overs, the roles reverse and it is now the fielding team's turn to bat and try to outscore the opposition.
There are also variations in the length of a game of cricket. In professional cricket this ranges from a limit of 20 overs per side (Twenty20) to a game played over 5 days (Test cricket, which is considered the highest level of the game). Depending on the form of the match being played, there are different rules that govern how a game is won, lost, drawn or tied. The rules of two-innings games are known as the Laws of Cricket and maintained by the ICC and the Marylebone Cricket Club (MCC); additional Standard Playing Conditions for Test matches and One Day Internationals augment these laws. In one version of Indoor Cricket, matches include just 6 players per side and include two 12-over innings.
Cricket was first documented as being played in southern England in the 16th century. By the end of the 18th century, it had developed to the point where it had become the national sport of England. The expansion of the British Empire led to cricket being played overseas and by the mid-19th century the first international matches were being held. Today, the game's governing body, the International Cricket Council (ICC), has 104 member countries. With its greatest popularity in the Test playing countries, cricket is the world's second most popular sport after Association football
