Encuentros De N Equipos En Futbol

Estrategia para generar emparejamientos de "n" equipos en una liga:

1. En la primera fila se colocan los números de equipo secuencialmente.

2. Si el número más alto es impar, añade un equipo más (el "equipo fantasma").

3. Mantén fijo el último número en la última columna.

4. En las filas siguientes, rota los números a la derecha (excepto el último número) hasta que se complete una rotación.

5. Empareja los equipos de la siguiente manera: el primero con el último, el segundo con el penúltimo, etc.

6. Anora los emparejamientos.

7. El jugador al que le toque con el "equipo fantasma" descansa esa jornada.

Ejemplo con 4 equipos (o 3 equipos usando el 4º como "equipo fantasma"):

-----------------

| 1 | 2 | 3 | 4 | ---> Jornada 1: 1-4, 2-3

-----------------

| 3 | 1 | 2 | 4 | ---> Jornada 2: 3-4, 1-2

-----------------

| 2 | 3 | 1 | 4 | ---> Jornada 3: 2-4, 3-1

-----------------

(Las filas de números se han generado aplicando los pasos del 1 al 4; las jornadas según el paso nº 5)History

Two of the earliest recorded football type games from Europe include Episkyros [6][7] from Ancient Greece and the Roman version Harpastum[6] which similar to pre-codified "Mob Football" involved more handling the ball than kicking.[8] Many earlier competitive games revolving around the kicking of a ball have been played in a few countries throughout history, such as cuju in China.[9] Non-competitive games included kemari in Japan and woggabaliri in Australia. The modern rules of association football are based on the mid-19th century efforts to standardise the widely varying forms of football played in the public schools of England. The history of football in England dates back to at least the eighth century.[10]

The Cambridge Rules, first drawn up at Cambridge University in 1848, were particularly influential in the development of subsequent codes, including association football. The Cambridge Rules were written at Trinity College, Cambridge, at a meeting attended by representatives from Eton, Harrow, Rugby, Winchester and Shrewsbury schools. They were not universally adopted. During the 1850s, many clubs unconnected to schools or universities were formed throughout the English-speaking world, to play various forms of football. Some came up with their own distinct codes of rules, most notably the Sheffield Football Club, formed by former public school pupils in 1857,[11] which led to formation of a Sheffield FA in 1867. In 1862, John Charles Thring of Uppingham School also devised an influential set of rules.[12]

These ongoing efforts contributed to the formation of The Football Association (The FA) in 1863, which first met on the morning of 26 October 1863 at the Freemasons' Tavern in Great Queen Street, London.[13] The only school to be represented on this occasion was Charterhouse. The Freemason's Tavern was the setting for five more meetings between October and December, which eventually produced the first comprehensive set of rules. At the final meeting, the first FA treasurer, the representative from Blackheath, withdrew his club from the FA over the removal of two draft rules at the previous meeting: the first allowed for running with the ball in hand; the second for obstructing such a run by hacking (kicking an opponent in the shins), tripping and holding. Other English rugby clubs followed this lead and did not join the FA and instead in 1871 formed the Rugby Football Union. The eleven remaining clubs, under the charge of Ebenezer Cobb Morley, went on to ratify the original thirteen laws of the game.[13] These rules included handling of the ball by "marks" and the lack of a crossbar, rules which made it remarkably similar to Victorian rules football being developed at that time in Australia. The Sheffield FA played by its own rules until the 1870s with the FA absorbing some of its rules until there was little difference between the games.[14]

The laws of the game are currently determined by the International Football Association Board (IFAB).[15] The Board was formed in 1886[16] after a meeting in Manchester of The Football Association, the Scottish Football Association, the Football Association of Wales, and the Irish Football Association. The world's oldest football competition is the FA Cup, which was founded by C. W. Alcock and has been contested by English teams since 1872. The first official international football match took place in 1872 between Scotland and England in Glasgow, again at the instigation of C. W. Alcock. England is home to the world's first football league, which was founded in Birmingham in 1888 by Aston Villa director William McGregor.[17] The original format contained 12 clubs from the Midlands and Northern England. FIFA, the international football body, was formed in Paris in 1904 and declared that they would adhere to Laws of the Game of the Football Association.[18] The growing popularity of the international game led to the admittance of FIFA representatives to the International Football Association Board in 1913. The board currently consists of four representatives from FIFA and one representative from each of the four British associations.[19]

Today, football is played at a professional level all over the world. Millions of people regularly go to football stadiums to follow their favourite teams,[20] while billions more watch the game on television or on the internet.[21] A very large number of people also play football at an amateur level. According to a survey conducted by FIFA published in 2001, over 240 million people from more than 200 countries regularly play football.[22] Football has the highest global television audience in sport.[23]

In many parts of the world football evokes great passions and plays an important role in the life of individual fans, local communities, and even nations. R. Kapuscinski says that people who are polite, modest or even humble in Europe fall easily into rage with playing or watching soccer games.[24] The Côte d'Ivoire national football team helped secure a truce to the nation's civil war in 2006[25] and it helped further reduce tensions between government and rebel forces in 2007 by playing a match in the rebel capital of Bouaké, an occasion that brought both armies together peacefully for the first time.[26] By contrast, football is widely considered to have been the final proximate cause for the Football War in June 1969 between El Salvador and Honduras.[27] The sport also exacerbated tensions at the beginning of the Yugoslav Wars of the 1990s, when a match between Dinamo Zagreb and Red Star Belgrade degenerated into rioting in May 1990.[28]

Etymology and names

Main article: Names for association football

The rules of association football were codified in England by the Football Association in 1863 and the name association football was coined to distinguish the game from the other forms of football played at the time, specifically rugby football. The term soccer originated in England, first appearing in the 1880s as an Oxford "-er" abbreviation of the word "association".[29]

Within the English-speaking world, association football is now usually called football in the United Kingdom, and mainly soccer in Canada and the United States. Other countries, such as Australia and New Zealand, may use either or both terms.

Gameplay

Association football is played in accordance with a set of rules known as the Laws of the Game. The game is played using a spherical ball (of 71 cm (28 in) circumference in FIFA play), known as the football (or soccer ball). Two teams of eleven players each compete to get the ball into the other team's goal (between the posts and under the bar), thereby scoring a goal. The team that has scored more goals at the end of the game is the winner; if both teams have scored an equal number of goals then the game is a draw. Each team is led by a captain who has only one official responsibility as mandated by the Laws of the Game: to be involved in the coin toss prior to kick-off or penalty kicks.[30]

The primary law is that players other than goalkeepers may not deliberately handle the ball with their hands or arms during play, though they do use their hands during a throw-in restart. Although players usually use their feet to move the ball around, they may use any part of their body (notably, "heading" with the forehead)[31] other than their hands or arms.[32] Within normal play, all players are free to play the ball in any direction and move throughout the pitch, though the ball cannot be received in an offside position.[33]

In typical game play, players attempt to create goal-scoring opportunities through individual control of the ball, such as by dribbling, passing the ball to a team-mate, and by taking shots at the goal, which is guarded by the opposing goalkeeper. Opposing players may try to regain control of the ball by intercepting a pass or through tackling the opponent in possession of the ball; however, physical contact between opponents is restricted. Football is generally a free-flowing game, with play stopping only when the ball has left the field of play or when play is stopped by the referee for an infringement of the rules.
