Cricket

Cricket is a bat-and-ball game played between two teams of eleven players on a field at the centre of which is a 22-yard (20-metre) pitch with a wicket at each end, each comprising two bails balanced on three stumps. Two players from the batting team (the striker and nonstriker) stand in front of either wicket, with one player from the fielding team (the bowler) bowling the ball towards the striker's wicket from the opposite end of the pitch. The striker's goal is to hit the bowled ball and then switch places with the nonstriker, with the batting team scoring one run for each exchange. Runs are also scored when the ball reaches or crosses the boundary of the field or when the ball is bowled illegally. The fielding team tries to prevent runs from being scored by dismissing batters (so they are "out"). Means of dismissal include being bowled, when the ball hits the striker's wicket and dislodges the bails, and by the fielding side either catching the ball after it is hit by the bat, but before it hits the ground, or hitting a wicket with the ball before a batter can cross the crease in front of the wicket. When ten batters have been dismissed, the innings ends and the teams swap roles. The game is adjudicated by two umpires, aided by a third umpire and match referee in international matches. They communicate with two off-field scorers who record the match's statistical information. Forms of cricket range from Twenty20 (also known as T20), with each team batting for a single innings of 20 overs (each "over" being a set of 6 fair opportunities for the batting team to score) and the game generally lasting three to four hours, to Test matches played over five days. Traditionally cricketers play in all-white kit, but in limited overs cricket they wear club or team colours. In addition to the basic kit, some players wear protective gear to prevent injury caused by the ball, which is a hard, solid spheroid made of compressed leather with a slightly raised sewn seam enclosing a cork core layered with tightly wound string. >Cricket is one of many games in the "club ball" sphere that basically involve hitting a ball with a hand-held implement; others include baseball (which shares many similarities with cricket, both belonging in the more specific bat-and-ball games category[2]), golf, hockey, tennis, squash, badminton and table tennis.[3] In cricket's case, a key difference is the existence of a solid target structure, the wicket (originally, it is thought, a "wicket gate" through which sheep were herded), that the batter must defend.[4] The cricket historian Harry Altham identified three "groups" of "club ball" games: the "hockey group", in which the ball is driven to and from between two targets (the goals); the "golf group", in which the ball is driven towards an undefended target (the hole); and the "cricket group", in which "the ball is aimed at a mark (the wicket) and driven away from it".[5] It is generally believed that cricket originated as a children's game in the south-eastern counties of England, sometime during the medieval period.[4] Although there are claims for prior dates, the earliest definite reference to cricket being played comes from evidence given at a court case in Guildford in January 1597 (Old Style, equating to January 1598 in the modern calendar). The case concerned ownership of a certain plot of land and the court heard the testimony of a 59-year-old coroner, John Derrick, who gave witness that:[6][7][8] Being a scholler in the ffree schoole of Guldeford hee and diverse of his fellows did runne and play there at creckett and other plaies. Given Derrick's age, it was about half a century earlier when he was at school and so it is certain that cricket was being played c. 1550 by boys in Surrey.[8] The view that it was originally a children's game is reinforced by Randle Cotgrave's 1611 English-French dictionary in which he defined the noun "crosse" as "the crooked staff wherewith boys play at cricket" and the verb form "crosser" as "to play at cricket".[9][10]. Internationally, competitive swimming came into prominence with its inclusion in the modern Olympic Games from their inception in 1896. Olympic events were originally only for men, but women’s events were added in 1912. Before the formation of FINA, the Games included some unusual events. In 1900, for instance, when the Games’ swimming events were held on the Seine River in France, a 200-metre obstacle race involved climbing over a pole and a line of boats and swimming under them. Such oddities disappeared after FINA took charge. Under FINA regulations, for both Olympic and other world competition, race lengths came increasingly to be measured in metres, and in 1969 world records for yard-measured races were abolished. The kinds of strokes allowed were reduced to freestyle (crawl), backstroke, breaststroke, and butterfly. All four strokes were used in individual medley races. Many nations have at one time or another dominated Olympic and world competition, including Hungary, Denmark, Australia, Germany, France, Great Britain, Canada, Japan, and the United States. >The earliest strokes to be used were the sidestroke and the breaststroke. The sidestroke was originally used with both arms submerged. That practice was modified toward the end of the 19th century by bringing forward first one arm above the water, then the other, and then each in turn. The sidestroke was supplanted in competitive swimming by the crawl (see below) but is still used in lifesaving and recreational swimming. The body stays on its side and the arms propel alternately. The leg motion used in sidestroke is called the scissors kick, in which the legs open slowly, under leg backward, upper leg forward, both knees slightly bent, and toes pointed. The scissoring action of the legs coming smartly together after opening creates the forward propulsion of the kick.

The feet kick out and down and then come back together in the middle. The hands stretch forward from the body while the head is kept underwater. The hands widen at the surface and then pull down and out. The swimmer breathes during the pull and exhales underwater.

The stroke is especially effective in rough water. As early as the end of the 17th century, the stroke was described as consisting of a wide pull of the arms combined with a symmetrical action of the legs and simulating the movement of a swimming frog, hence the usual term frog kick. The stroke is performed lying face down in the water, the arms always remaining underwater. The early breaststroke featured a momentary glide at the completion of the frog kick. Later the competitive breaststroke eliminated the glide. In the old breaststroke, breath was taken in at the beginning of the arm stroke, but in the later style, breath was taken in near the end of the arm pull.

The hands then move down the chest to the hips. The legs are kept together and thrust down like a flipper in a double rhythm matching the exit and entry of the hands from the water. Breath is inhaled while the hands are underwater. See all videos for this article The butterfly stroke, used only in competition, differs from the breaststroke in arm action. In the butterfly the arms are brought forward above the water. The stroke was brought to the attention of U.S. officials in 1933 during a race involving Henry Myers, who used the stroke. He insisted that his stroke conformed to the rules of breaststroke as then defined. After a period of controversy, the butterfly was recognized as a distinct competitive stroke in 1953. The frog kick originally used was abandoned for a fishtail (dolphin) kick, depending only on up-and-down movement of the legs. Later swimmers used two dolphin kicks to one arm pull. Breathing is done in sprint competition by raising the head every second or third stroke.
