Basketball Referee
In basketball, an official (usually called a referee) enforces the rules and maintains order in the game. The title of official also applies to the scorers and timekeepers, as well as other personnel that have an active task in maintaining the game. Basketball is regarded as among the most difficult sports to officiate due to the speed of play, complexity of rules, the case-specific interpretations of rules, and the instantaneous decision required. There is one lead referee and one or two umpires, depending on whether there is a two- or three-person crew. In the NBA, the lead official is called the crew chief with one referee and one umpire. In FIBA-sanctioned play, two-man crews consist of a referee and an umpire, and three-man crews contain a referee and two umpires. Regardless, both classes of officials have equal rights to control almost all aspects of the game. In most cases, the lead official (in FIBA, the referee) performs the jump ball to begin the contest, though N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sports Officiating
Sport pertains to any form of competitive physical activity or game that aims to use, maintain, or improve physical ability and skills while providing enjoyment to participants and, in some cases, entertainment to spectators. Sports can, through casual or organized participation, improve participants' physical health. Hundreds of sports exist, from those between single contestants, through to those with hundreds of simultaneous participants, either in teams or competing as individuals. In certain sports such as racing, many contestants may compete, simultaneously or consecutively, with one winner; in others, the contest (a ''match'') is between two sides, each attempting to exceed the other. Some sports allow a "tie" or "draw", in which there is no single winner; others provide tie-breaking methods to ensure one winner and one loser. A number of contests may be arranged in a tournament producing a champion. Many sports leagues make an annual champion by arranging games ...

Double Dribble
In basketball, an illegal dribble (colloquially called a double dribble or dribbling violation) occurs when a player ends their dribble by catching or causing the ball to come to rest in one or both hands and then dribbles it again with one hand or when a player touches it before the ball hits the ground. The dribble also ends when the dribbler palms/carries the ball by allowing it to come to rest in one or both hands. This is a palming/carrying the ball violation if the player continues with another dribble. There is no violation during the jump ball, a throw-in or a free throw. Official NBA rules In the National Basketball Association, a dribble is movement of the ball, caused by a player in control, who throws or touches the ball into the air or to the floor. The dribble ends when the player: # Touches the ball simultaneously with both hands. # Permits the ball to come to rest while the player is in control of it. # Touches the ball more than once while dribbling, before it ...

Traveling (basketball)
In basketball, travelling is a violation of the rules that occurs when a player holding the ball moves one or both their feet illegally. Traveling is also called, predominantly in a streetball game, "walking" or "steps". If the pivot foot is lifted, a pass or try for made basket must be made before the pivot foot is replaced to the floor. In the NBA and FIBA, players are also given a "gather step". In the NBA and FIBA, when a player has taken more than two steps without the ball being dribbled, a traveling violation is called. The NCAA and NFHS do not allow two steps. In 2018, FIBA revised the rule so that one can take a "gather step" before taking the two steps. A travel can also be called via carrying or an unestablished pivot foot. If the pivot foot of a player changes or moves, it is considered traveling. In basketball Definitions NCAA Rule 9, Section 5. Traveling Art. 1. A player shall not travel with the ball. Art. 2. Traveling occurs when a player holding the bal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instant Replay
Instant replay or action replay is a video reproduction of something that recently occurred which was both shot and broadcast live. The video, having already been shown live, is replayed in order for viewers to see again and analyze what had just taken place. Some sports allow officiating calls to be overturned after the review of a play. Instant replay is most commonly used in sports, but is also used in other fields of live TV. While the first near-instant replay system was developed and used in Canada, the first ''instant'' replay was developed and deployed in the United States. Outside of live action sports, instant replay is used to cover large pageants or processions involving major dignitaries (e.g. monarchs, religious leaders such as the Catholic Pope, revolutionary leaders with mass appeal), political debate, legal proceedings (e.g. O.J. Simpson murder case), royal weddings, red carpet events at major award ceremonies (e.g. the Oscars), grandiose opening ceremoni ...

Triangle
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices ''A'', ''B'', and ''C'' is denoted \triangle ABC. In Euclidean geometry, any three points, when non- collinear, determine a unique triangle and simultaneously, a unique plane (i.e. a two-dimensional Euclidean space). In other words, there is only one plane that contains that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is only one plane and all triangles are contained in it; however, in higher-dimensional Euclidean spaces, this is no longer true. This article is about triangles in Euclidean geometry, and in particular, the Euclidean plane, except where otherwise noted. Types of triangle The terminology for categorizing triangles is more than two thousand years old, having been defined on the very first page of Euclid's Elements. The names used for modern classification are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Throw
In basketball, free throws or foul shots are unopposed attempts to score points by shooting from behind the free-throw line (informally known as the foul line or the charity stripe), a line situated at the end of the restricted area. Free throws are generally awarded after a foul on the shooter by the opposing team, analogous to penalty shots in other team sports. Free throws are also awarded in other situations, including technical fouls, and when the fouling team has entered the '' bonus/penalty situation'' (after a team commits a requisite number of fouls, each subsequent foul results in free throws regardless of the type of foul committed). Also, depending on the situation, a player may be awarded between one and three free throws. Each successful free throw is worth one point. Description In the NBA, most players make 70–80% of their attempts. The league's best shooters (such as Mark Price, Steve Nash, Steve Kerr, Rick Barry, Larry Bird, Ray Allen, José Calderón, ...

Whistle
A whistle is an instrument which produces sound from a stream of gas, most commonly air. It may be mouth-operated, or powered by air pressure, steam, or other means. Whistles vary in size from a small slide whistle or nose flute type to a large multi-piped church organ. Whistles have been around since early humans first carved out a gourd or branch and found they could make sound with it. In prehistoric Egypt, small shells were used as whistles. Many present day wind instruments are inheritors of these early whistles. With the rise of more mechanical power, other forms of whistles have been developed. One characteristic of a whistle is that it creates a pure, or nearly pure, tone. The conversion of flow energy to sound comes from an interaction between a solid material and a fluid stream. The forces in some whistles are sufficient to set the solid material in motion. Classic examples are Aeolian tones that result in galloping power lines, or the Tacoma Narrows Bridge (th ...
