Playfield
A pitch or a sports ground is an outdoor playing area for various sports. The term ''pitch'' is most commonly used in British English, while the comparable term in American and Canadian English is playing field or sports field. For most sports the official term is field of play, although this is not regularly used by those outside refereeing/umpiring circles. The field of play generally includes out-of-bounds areas that a player is likely to enter while playing a match, such as the area beyond the touchlines in association football and rugby or the sidelines in American and Canadian football, or the "foul territory" in baseball. The surface of a pitch is most commonly composed of sod (grass), but may also be artificial turf, sand, clay, gravel, concrete, or other materials. A playing field on ice may be referred to as a ''rink'', for example an ice hockey rink, although ''rink'' may also refer to the entire building or, in the sport of curling, to either the building or a partic ...

Comparison Sport Playing Areas
Comparison or comparing is the act of evaluating two or more things by determining the relevant, comparable characteristics of each thing, and then determining which characteristics of each are similar to the other, which are different, and to what degree. Where characteristics are different, the differences may then be evaluated to determine which thing is best suited for a particular purpose. The description of similarities and differences found between the two things is also called a comparison. Comparison can take many distinct forms, varying by field: To compare things, they must have characteristics that are similar enough in relevant ways to merit comparison. If two things are too different to compare in a useful way, an attempt to compare them is colloquially referred to in English as "comparing apples and oranges." Comparison is widely used in society, in science and in the arts. General usage Comparison is a natural activity, which even animals engage in when deci ...

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baseball Field
A baseball field, also called a ball field or baseball diamond, is the field upon which the game of baseball is played. The term can also be used as a metonym for a baseball park. The term sandlot is sometimes used, although this usually refers to less organized venues for activities like sandlot ball. Specifications :''Unless otherwise noted, the specifications discussed in this section refer to those described within the Official Baseball Rules, under which Major League Baseball is played.'' The starting point for much of the action on the field is home plate (officially "home base"), a five-sided slab of white rubber. One side is long, the two adjacent sides are . The remaining two sides are approximately and set at a right angle. The plate is set into the ground so that its surface is level with the field. The corner of home plate where the two 11-inch sides meet at a right angle is at one corner of a square. The other three corners of the square, in counterclockwise or ...

Bandy Field
A bandy field or bandy rink is a large ice rink used for playing the team winter sport of bandy. Being about the size of a football pitch, it is substantially larger than an ice hockey rink. History Originally, bandy was played on naturally frozen ice, mainly on lakes. Teams often had to take time to go out and search for the best ice to use. Soon, ice started to be created on soccer pitches in the wintertime, allowing for a more safe place to play. This may be the reason the outer measurements are the same as for a soccer field. The first artificially frozen bandy field was created in Budapest, Hungary, in 1923. In the 1980s, indoor arenas started to be built, allowing for a longer season. The world's first indoor bandy arena, the Olimpiyskiy, was built in Moscow for the 1980 Summer Olympics but has hosted many bandy events since. Size The size of a bandy field is regulated in section 1.1 of the Bandy Playing Rules set up by the Federation of International Bandy It shall be rec ...

Track And Field
Track and field is a sport that includes athletic contests based on running, jumping, and throwing skills. The name is derived from where the sport takes place, a running track and a grass field for the throwing and some of the jumping events. Track and field is categorized under the umbrella sport of athletics, which also includes road running, cross country running and racewalking. The foot racing events, which include sprints, middle- and long-distance events, racewalking, and hurdling, are won by the athlete who completes it in the least time. The jumping and throwing events are won by those who achieve the greatest distance or height. Regular jumping events include long jump, triple jump, high jump, and pole vault, while the most common throwing events are shot put, javelin, discus, and hammer. There are also "combined events" or "multi events", such as the pentathlon consisting of five events, heptathlon consisting of seven events, and decathlon consisting of ...

Football Pitch
A football pitch (also known as soccer field) is the playing surface for the game of association football. Its dimensions and markings are defined by Law 1 of the Laws of the Game, "The Field of Play". The pitch is typically made of natural turf or artificial turf, although amateur and recreational teams often play on dirt fields. Artificial surfaces are allowed only to be green in colour. All line markings on the pitch form part of the area which they define. For example, a ball on or above the touchline is still on the field of play, and a foul committed over the line bounding the penalty area results in a penalty. Therefore, a ball has to completely cross the touchline to be out of play, and a ball has to wholly cross the goal line (between the goal posts) in order for a goal to be scored; if any part of the ball is still on or above the line, a goal is not scored and the ball is still in play. The field descriptions that apply to adult matches are described below. Because ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Rules Football
Australian football, also called Australian rules football or Aussie rules, or more simply football or footy, is a contact sport played between two teams of 18 players on an oval field, often a modified cricket ground. Points are scored by kicking the oval ball between the central goal posts (worth six points), or between a central and outer post (worth one point, otherwise known as a "behind"). During general play, players may position themselves anywhere on the field and use any part of their bodies to move the ball. The primary methods are kicking, handballing and running with the ball. There are rules on how the ball can be handled; for example, players running with the ball must intermittently bounce or touch it on the ground. Throwing the ball is not allowed, and players must not get caught holding the ball. A distinctive feature of the game is the mark, where players anywhere on the field who catch the ball from a kick (with specific conditions) are awarded unimped ...

American Football Field
The rectangular field of play used for American football games measures long between the goal lines, and (53.3 yards) wide. The field may be made of grass or artificial turf. In addition, there are end zones extending another past the goal lines to the "end lines", for a total length of . When the "football field" is used as unit of measurement, it is usually understood to mean , although technically the full length of the official field, including the end zones, is . There is a goal centered on each end line, with a crossbar above the ground and goalposts apart extending at least above the crossbar. Between the goal lines, additional lines span the width of the field at 5-yard intervals. This appearance led to the use of the term gridiron in the 1880s. For a few years in the early 20th century, lines perpendicular to the lines at 5-yard intervals spanned the length of the field, giving it a checkerboard-like appearance. This article mainly describes the field used in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Regulation Of Sport
The regulation of sport is usually done by a sport governing body for each sport, resulting in a core of relatively invariant, agreed rules. People responsible for leisure activities often seek recognition and respectability as sports by joining sports federations such as the International Olympic Committee, or by forming their own regulatory body. In this way sports evolve from leisure activity to more formal sports: relatively recent newcomers are BMX cycling, snowboarding, wrestling, etc. Some of these activities have been popular but uncodified pursuits for different lengths of time. Indeed, the formal regulation of sport is a relatively modern and increasing development. This method promotes a sport globally, in a very successful way. It also promotes the universality of each sport, by ensuring that the same gameplay rules are being practiced worldwide, using a standardized/homogenous international gameplay rule system (sanctioned by the respective international sports gove ...

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 pitch with a wicket at each end, each comprising two bails balanced on three stumps. The batting side scores runs by striking the ball bowled at one of the wickets with the bat and then running between the wickets, while the bowling and fielding side tries to prevent this (by preventing the ball from leaving the field, and getting the ball to either wicket) and dismiss each batter (so they are "out"). Means of dismissal include being bowled, when the ball hits the stumps 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 ...

Cricket Pitch
In the game of cricket, the cricket pitch consists of the central strip of the cricket field between the wickets. It is long (1 chain) and wide. The surface is flat and is normally covered with extremely short grass, but can be completely dry or dusty soil with barely any grass or, in some circumstances (that are rarely seen in high level cricket), made from an artificial material. Over the course of a cricket match, the pitch is not repaired or altered other than in special circumstances - meaning that it will change condition. Any grass on the pitch in the game's first over, for example, may have disappeared by twentieth over due to wear. As almost all deliveries bowled will bounce off the pitch towards the batter, the state and type of a cricket pitch can significantly affect the outcome of a match. For example, a dusty, very dry, pitch will favour spin bowling because the ball will grip more on a dusty pitch - giving the team with the superior spin bowlers a significan ...
