Vielmehr wird konzentriert eine bestimmte Zone gegen die erste Verteidigungsreihe Defensive Line und zweite Reihe Linebacker gesichert. Wir listen daher für fortgeschrittene Spieler diese kleinen Feinheiten auf. Amateure greifen hinzugegen zu Gummi oder Kunststoff, da diese Materialien deutlich günstiger sind. Das wiederum verrät der Defense etwas über den geplanten Spielzug. Nicht immer ist ein vermeintlicher Touchdown auch gültig.

Dann darf er vom Gegner nach dem Fang nicht angegriffen werden, kann aber keinen weiteren Raumgewinn erzielen. Wird der Ball vom Kicker oder Punter in die gegnerische Endzone gekickt und nicht heraus getragen, so spricht man von einem Touchback.

Auch auf der Seite des nicht kickenden Teams gibt es Spezialisten. So gehen etwa die Kick Blocker bzw. Punt Blocker aggressiv auf den Kicker bzw.

Punter während der Trittbewegung drauf und versuchen, den anfliegenden Football zu blocken. Aufgrund der Komplexität des American Footballs wird eine Footballmannschaft von mehreren Trainern gecoacht.

Der Head Coach ist der Oberste in der Trainerhierarchie. Er ist für die Betreuung der Mannschaft zuständig und überwacht sowohl das Training als auch alle Entscheidungen in einem Spiel.

Zusätzlich ist er für die Entwicklung der Spielzüge verantwortlich. Zusätzlich kann es weitere Trainer geben, beispielsweise für bestimmte Positionen, körperliche Leistungsfähigkeit oder koordinative Fähigkeiten.

Amateurmannschaften haben meistens drei bis fünf Trainer, semi- professionelle Mannschaften über zehn Trainer.

Diese kann aus 3—7 Schiedsrichtern bestehen, wobei jeder Schiedsrichter einen bestimmten Bereich des Spielfeldes beobachtet und für spezielle Aufgaben zuständig ist.

Er positioniert sich im Backfield der Offense und richtet über Downs und Strafen. Weitere Schiedsrichter sind der Umpire , der sich jeweils zwischen oder hinter den Linebackers aufstellt und meistens den Ball sichert und für den nächsten Spielzug positioniert.

Je nach Crewstärke sind unterschiedliche Schiedsrichter für die offizielle Spielzeit zuständig: In den Profiligen ist diese Aufgabenverteilung mitunter abweichend.

Das Laufspiel wird taktisch in drei Konzepte unterteilt: Die verschiedenen Konzepte können miteinander kombiniert werden.

Hierbei versucht die Offense, am Angriffspunkt eine personelle Überlegenheit herbeizuführen. Das Quickness Running Game basiert auf dem Versuch, den Angriffspunkt so schnell zu erreichen, dass der Defense keine Zeit für eine optimale Reaktion bleibt.

Drei Yards Raumgewinn gelten bereits als voller Erfolg. Zusätzlich wird das Laufspiel nach der Art der Blocksetzung unterschieden. Bei Zone Runs und ähnlichen Spielzügen werden nicht direkt einzelne Gegenspieler angegriffen.

Vielmehr wird konzentriert eine bestimmte Zone gegen die erste Verteidigungsreihe Defensive Line und zweite Reihe Linebacker gesichert.

Hinsichtlich des Gelingens eines solchen Spielzugs trägt der balltragende Runningback mehr Verantwortung als bei einem Standardlaufspiel.

Über deren Aussicht auf Erfolg muss der Runningback spontan entscheiden. Beim Inside Zone Play bleibt der Runningback zwischen den beiden Tackles, was ihm erlaubt auch die Seite zu wechseln, falls sich dort eine Lücke öffnet.

Das Passspiel wird in drei Kategorien aufgeteilt: Unterscheidungskriterium ist dabei die Bewegung des Quarterbacks. Aus dieser Position kann er üblicherweise das gesamte Spielfeld überblicken.

Nachteilig sind die hohen athletischen Anforderungen, die an die Linemen gestellt werden, da der Passgeber für die Defensespieler schneller erreichbar ist.

Da diese der Offense das Überraschungsmoment nimmt, wird sie meist nur eingesetzt, wenn ersichtlich ist, das ein Passspielzug folgt. Geschieht dies ohne jede Verzögerung spricht man vom Sprint Out, vollführt er zuvor andere Bewegungsabläufe, so spricht man vom Roll Out.

Der Quarterback sollte hierbei jedoch ein guter Sprinter sein. Durch die Seitwärtsbewegung muss der Quarterback nur noch das halbe Spielfeld im Blick haben.

Dies vereinfacht zwar die Beobachtung der Verteidigung, verringert aber die Anzahl der anspielbaren Passempfänger, da es ein sehr hohes Risiko bergen würde einen Pass auf die andere Spielfeldseite gegen die Laufrichtung zu werfen.

Dies soll die Verteidiger zu einer verzögerten Reaktion auf den Pass bewegen. Viele Spielzüge sind darauf ausgelegt, die Verteidigung zu verwirren.

Bei Fakes wird ein Spielzugart z. Fakes machen einen nicht unbedeutenden Teil der Taktiklastigkeit des Spieles aus. Dabei versucht die Defense Druck auf den Quarterback auszuüben, indem ein oder mehrere Spieler die Offense-Line durchbrechen bzw.

Der blitzende Spieler kann ein Linebacker oder ein Cornerback sein, manchmal sogar ein Safety. Erkennt der Quarterback, woher der Blitz kommt, hat er eine geschwächte Stelle der Verteidigung vor sich.

Zum Teil werden Blitzes auch nur angetäuscht, um den Quarterback zu verunsichern oder ihn zu einer schlechten Entscheidung zu verleiten.

Die D-Line-Spieler und Linebacker stellen sich in die für ihre Formation gewöhnlichen Positionen auf, tauschen aber ihre Assignments Aufgaben nach dem Snap mit dem Nebenmann oder mit einem vorher abgesprochenen Partner.

Das soll Abstimmungsschwierigkeiten innerhalb der gegnerischen Offensive Line hervorrufen. Ein ähnliches Ziel verfolgen die D-Line Shifts.

Das kann mehrere Wirkungen haben. Erstens kann es die Offensive Line durcheinander bringen, weil die geplanten Blockschemata evtl.

Zweitens zwingt es den Quarterback zu möglichen Audibles , die den Spielzug ändern, wenn er sieht, dass z. Das wiederum verrät der Defense etwas über den geplanten Spielzug.

Die Rückennummern haben üblicherweise eine feste Zuteilung zu den Positionen, nicht zuletzt zur Orientierung der Schiedsrichter.

Des Weiteren gibt es in vielen Teams so genannte retired numbers zurückgezogene Nummern. Seit werden alle vier Jahre Weltmeisterschaften ausgetragen.

American Football ist vor allem in Nordamerika verbreitet. Die mehreren hundert Mannschaften in den oberen Ligen des College Football spielen jeden Herbst etwa zwölf Spiele innerhalb ihrer jeweiligen Gruppe.

Seit den ern wird auch American Football in der Schweiz gespielt. Unterhalb der GFL befindet sich eine ebenso zweigeteilte 2. Ebenso gibt es umfangreichen Spielbetrieb im Jugendbereich.

Seit Ende der er Jahre wird Football auch auf Hochschulebene gespielt. Das Finale ist der jährlich ausgetragene Hochschulbowl. Kurz darauf treffen sich die besten Hochschulspieler in der universitären Nationalmannschaft, den GERmaniacs.

Zur Saison wurden die europäischen Wettbewerbe neu organisiert, sodass sich seitdem die sechs besten Teams Europas in der Big6 European Football League treffen.

Als weiterer Wettbewerb wurde der EFL Bowl eingeführt, in dem die besten nicht in der Big6 vertretenen Vereinsmannschaften aufeinander treffen.

Diese wurde eingestellt. Alle vier Jahre gibt es eine American-Football-Europameisterschaft , welche zuletzt in Österreich stattfand.

Receivers, for example, may play close to the other linemen or they may play some distance down the line of scrimmage, where they would sometimes be called split ends.

Of the four backs, they may play behind the linemen, or may play "split out" to provide additional wide receivers.

These additional receivers can be flankers if they play split far wide, but still in the backfield or slot receivers if they play in the "slot" between the split end and the rest of the offensive line.

The players on defense may arrange themselves in any manner, as long as all players are "behind the line" that is, on the side of the line nearest their own end zone.

Players who line up opposite the offensive line are called defensive linemen , usually with one or two defensive tackles in the middle a single defensive tackle is often called the nose guard or nose tackle and with one defensive end on each side.

A defensive lineman's job is typically to put pressure on the opposing teams quarterback by rushing the offensive line.

The defensive line is also most often the first set of players the opponent must get through should they choose to run the ball. Behind the linemen are the linebackers.

A linebackers job can be any number of things, including trying to rush the opposing teams quarterback, stopping the opponents running back on run plays, or covering the opponents tight end or wide receivers.

Positioned opposite the wide receivers are the cornerbacks. Their primary responsibility is to cover the wide receivers.

Farthest back from the line are the safeties , usually in the middle of the field behind the linebackers.

The safeties are the last line of defense against the opponent. Like a linebacker, a safety's role can vary, however their most common role is to help the cornerbacks cover the opponent's wide receivers, which is called "double coverage".

The linemen and linebackers close to the line of scrimmage, are often referred to as playing "in the box". Players outside "the box" usually cornerbacks and safeties are collectively referred to as the "secondary".

A scrimmage down begins with a snap , where the center throws or hands the ball backward to one of the backs, usually the quarterback.

The quarterback then either hands the ball off to a back, throws the ball, or runs with it himself. The down ends when the ball becomes dead see below.

The ball is typically next spotted where the ball became dead; however, if it became dead outside the hash marks, it is brought in on the same yard line to the nearest hash mark.

This spot becomes the line of scrimmage for the next play. In the case of an incomplete forward pass, the ball is returned to the spot where it was last snapped to begin the next play.

A fumbled ball that goes out of bounds is declared dead and possession remains with the team that most recently had control of the ball.

The nearest official typically blows his whistle after the ball becomes dead to alert the players that the down has already ended. If the ball is alive and the official sounds an inadvertent whistle , then the ball still becomes dead, but the team in possession of the ball may elect to have the down replayed or take the spot where the ball was declared dead.

If the ball was loose from a fumble, then the ball can be put into play at the spot of the fumble. If the ball was in flight from a kick or a pass, then the down is always replayed.

A free kick is a down which does not occur from scrimmage. The kicking team begins behind the ball, while the receiving team must remain at least 10 yards downfield before the ball is kicked.

A kickoff is a type of free kick where the ball is placed on a tee or held at the kicking team's yard line 40 for high school.

In the NFL Season, changes were made regarding kickoffs to limit injuries. Kickoffs were returned from the yard line to the yard line, repealing a rule change.

In addition, players on the kickoff coverage team cannot line up more than 5 yards behind the kickoff line, minimizing running starts and thus reducing the speed of collisions.

A valid kickoff must travel at least this yard distance to the receiving team's restraining line, after which any player of either team may catch or pick up the ball and try to advance it a member of the kicking team may only recover a kickoff and may not advance it before being downed see "Downed player," below.

In most cases, the ball is kicked as far as possible typically 40 to 70 yards , after which a player of the receiving team is usually able to secure possession since the members of the kicking team cannot start downfield until after the ball is kicked.

Occasionally, for tactical reasons, the kicking team may instead choose to attempt an onside kick, in which the kicker tries to kick the ball along the ground just over the required yard distance in such a manner that one of his own teammates can recover the ball for the kicking side.

If it is touched before ten yards, the ball is dead and a re-kick or spot of the ball will be rewarded to the receiving team.

A member of the receiving team gaining possession of the ball on a kickoff may attempt to advance it as far as he can toward the kicking team's goal line before being downed.

Once the ball carrier is downed, the play is whistled dead and the ball is placed by the officials at the point where the play ended; this spot then becomes the line of scrimmage for the ensuing play.

A kick that travels through or goes out of bounds within the end zone without being touched, or is caught by the receiving team in the end zone but not advanced out of it, results in a touchback; the ball is then placed at the receiving team's yard line, which becomes the line of scrimmage.

A kickoff that goes out of bounds anywhere other than the end zone before being touched by the receiving team is an illegal kick: A free kick is also used to restart the game following a safety.

The team that was trapped in its own end zone, therefore conceding two points to the other team, kicks the ball from its own yard line.

This can be a place kick in the NFL, a tee cannot be used , drop kick or punt. In the NFL and high school, a free kick may be taken on the play immediately after a fair catch ; see "fair catch kick" below.

A field goal is scored when the ball is place kicked, drop kicked, or free kicked after a fair catch or awarded fair catch High School or NFL only between the goal posts behind the opponent's end zone.

The most common type of kick used is the place kick. For a place kick, the ball must first be snapped to a placeholder, who holds the ball upright on the ground with his fingertip so that it may be kicked.

Three points are scored if the ball crosses between the two upright posts and above the crossbar and remains over.

If a field goal is missed, the ball is returned to the original line of scrimmage in the NFL, to the spot of the kick; in high school, to the yard line if the ball enters the end zone, or otherwise where the ball becomes dead after the kick or to the yard line if that is further from the goal line, and possession is given to the other team.

If the ball does not go out of bounds, the other team may catch the kicked ball and attempt to advance it, but this is usually not advantageous.

One official is positioned under each goalpost; if either one rules the field goal no good, then the field goal is unsuccessful.

A successful field goal is signaled by an official extending both arms vertically above the head. A team that successfully kicks a field goal kicks off to the opposing team on the next play.

A touchdown is earned when a player has legal possession of the ball and the ball touches or goes over the imaginary vertical plane above the opposing team's goal line.

After a touchdown, the scoring team attempts a try for 1 or 2 points see below. A successful touchdown is signaled by an official extending both arms vertically above the head.

A touchdown is worth six points, except in the defunct WFL where it was worth seven points. For statistical purposes, the player who advances the ball into or catches it in the end zone is credited with the touchdown.

If a forward pass was thrown on the play, the throwing player is also credited with a passing touchdown. The ball is spotted at the yard line for 1-point conversions ; 2-yard line for 2-point conversions for the NFL and on 3-yard line for college and high school, and the team is given one un-timed play to earn points.

The uncommon safety is scored if a player causes the ball to become dead in his own end zone; two points are awarded to the opposing usually defending team.

This can happen if a player is either downed or goes out of bounds in the end zone while carrying the ball, or if he fumbles the ball, and it goes out of bounds in the end zone.

A safety is also awarded to the defensive team if the offensive team commits a foul which is enforced in its own end zone.

A safety is not awarded if a player intercepts a pass or receives a kick in his own end zone and is downed there.

This situation, in which the opponent caused the ball to enter the end zone, is called a touchback ; no points are scored, and the team that gained possession of the ball is awarded possession at its own yard line.

If the interception or reception occurs outside the end zone, and the player is carried into the end zone by momentum, the ball is placed at the spot of the catch and no safety is awarded.

A safety is signaled by a referee holding both palms together above the head, fingertips pointing upwards. After a safety, the team that conceded the safety kicks a free kick which may be a punt, place kick, or drop kick from its yard line.

A free kick see above may be taken on the play immediately after any fair catch of a punt. The ball must be held on the ground by a member of the kicking team or drop kicked; a tee may not be used.

High school kickers may use a tee. This is both a field goal attempt and a free kick; if the ball is kicked between the goal posts, three points are scored for the kicking team.

This is the only case where a free kick may score points. This method of scoring is extremely rare, last successfully completed in the NFL by Ray Wersching in It is only advantageous when a team catches a very short punt with very little time left.

Note that a team is unlikely to be punting with only a few seconds left in a half or overtime, and it is rarer still for punts to be caught near field goal range.

The officials' signal for a successful fair catch kick is the same as for a field goal. The game is officiated by a crew of three to seven officials.

Every crew will consist of a referee , who is generally in charge of the game and watches action on the quarterback and in the offensive backfield; an umpire , who handles spotting the ball and watches action on the offensive line; and a head linesman , who supervises placement of the down box and line-to-gain chains.

The crew may also consist of a line judge , back judge , field judge and side judge , in the order listed: Officials are selected by the teams in advance or appointed by the governing league.

While the majority of officials at lower levels only officiate games on a part-time basis, the NFL is implementing a new system where seven officials will become full-time employees of the league, one for each official position i.

During the game, the officials are assisted in the administration of the game by other persons, including: These individuals may be provided by the teams involved — it is common for a high school coach's son or daughter to act as ball boy for the team.

Because football is a high- contact sport requiring a balance between offense and defense, many rules exist that regulate equality, safety, contact, and actions of players on each team.

It is very difficult to always avoid violating these rules without giving up too much of an advantage. Thus, an elaborate system of fouls and penalties has been developed to "let the punishment fit the crime" and maintain a balance between following the rules and keeping a good flow of the game.

Players are constantly looking for ways to find an advantage that stretches the limitations imposed by the rules.

Also, the frequency and severity of fouls can make a large difference in the outcome of a game, so coaches are constantly looking for ways to minimize the number and severity of infractions committed by their players.

It is a common misconception that the term "penalty" is used to refer both to an infraction and the penal consequence of that infraction. A foul is a rule infraction for which a penalty is prescribed.

In most cases when a foul occurs, the offending team will be assessed a penalty of 5, 10 or 15 yards, depending on the foul.

Also, in most cases, if the foul is committed while the ball is in play, the down will be replayed from the new position for example, if the offense commits a foul on a first-down play, the next play will still be first down, but the offense may have to go 15 yards, or farther, to achieve another first down.

But if a defensive foul results in the ball advancing beyond the offense's first-down objective, the next play will be the first down of a new series.

Some penalties typically for more serious fouls , however, require a loss of down for the offense; and some defensive fouls may result in an automatic first down regardless of the ball position.

In all cases except for ejection of a player or, in rare cases, forfeiture of the game , the non-offending team is given the option of declining the penalty and letting the result of the play stand although the Referee may exercise this option on their behalf when it is obvious , if they believe it to be more to their advantage.

It is divided by 20 lines drawing every 5 yards. The field has two other sets of markings, running between the two end zones along the length of the field, known as "hashmarks".

All plays must start between the hashmarks—if the last play ended outside the hashmarks, the ball is moved to the nearest hashmark.

At the ends of the field there are scoring areas, called the end zones. There are also two yellow poles on the end of each field called uprights.

Sometimes, if the team can not score a touchdown they might want to kick it through the uprights for three points.

The uprights are also used for scoring one point after a team scored a touchdown. There are many types of players on a football team.

For the offensive part of the team, a quarterback throws the football to wide receivers while offensive linemen block to protect him from defensive players.

The offensive linemen also block when a running back runs to advance the football. Players on the Defensive line , a linebacker , and defensive backs cornerbacks and American football safeties attempt to tackle the offensive player who carries the football.

Some team members only play during certain times. These players belong to the Special Teams. The kicker can kick the ball to the other team or between the uprights, while the placeholder holds the ball steady.

The kick returner runs the ball down the field in an attempt to score points after catching the ball. A touchdown is achieved when a player has legal possession of the ball and the ball crosses an imaginary vertical plane above the opposing team's goal line.

After a touchdown, the scoring team attempts a try for 1 or 2 points see below. A successful touchdown is signaled by an official extending both arms vertically above the head.

A field goal is scored when the ball is place kicked between the goal posts behind the opponent's end zone. The most common type of kick used is the place kick.

For a place kick, the ball must first be snapped to a placeholder, who holds the ball upright on the ground with his fingertip so that it may be kicked.

Three points are scored if the ball crosses between the two upright posts and above the crossbar and remains over. Immediately following a touchdown, the scoring team can attempt to kick the ball between the goal posts for 1 extra point.

The team can also run or pass the ball into the end zone for 2 points. This is not done very often although it does happen. A safety is scored if a player causes the ball to become dead in his own end zone.

When this happens two points are awarded to the opposing usually defending team. This can happen if a player is either downed or goes out of bounds in the end zone while carrying the ball.

Der "freie Mann" im Rückraum. Paderborn bochum live stream passiert jewel deutsch einem Down? Stellen Sie sich trotzdem darauf ein, einige englische Begriffe zu lesen und auch selbst zu verwenden. Dies soll die Verteidiger zu einer verzögerten Reaktion auf den Pass bewegen. Gleichzeitig besteht die Gefahr, dass der Gegner den Ball in einer guten Position übernimmt. Erstens kann es die Offensive Line durcheinander bringen, weil die geplanten Blockschemata evtl. Einige weitere, kleinere Abweichungen gibt es zusätzlich.

Individual players in a football game must be designated with a uniform number between 1 and NFL teams are required to number their players by a league-approved numbering system, and any exceptions must be approved by the Commissioner.

The role of the offensive unit is to advance the football down the field with the ultimate goal of scoring a touchdown. The offensive team must line up in a legal formation before they can snap the ball.

An offensive formation is considered illegal if there are more than four players in the backfield or fewer than five players numbered 50—79 on the offensive line.

Interior offensive linemen are not allowed to move until the snap of the ball. The quarterback is the leader of the offense.

Either the quarterback or a coach calls the plays. Quarterbacks typically inform the rest of the offense of the play in the huddle before the team lines up.

The quarterback lines up behind the center to take the snap and then hands the ball off, throws it or runs with it. The primary role of the halfback, also known as the running back or tailback, is to carry the ball on running plays.

Halfbacks may also serve as receivers. Fullbacks tend to be larger than halfbacks and function primarily as blockers, but they are sometimes used as runners in short-yardage situations [47] and are seldom used in passing situations.

The offensive line OL consists of several players whose primary function is to block members of the defensive line from tackling the ball carrier on running plays or sacking the quarterback on passing plays.

The principal receivers are the wide receivers WR and the tight ends TE. The main goal of the wide receiver is to catch passes thrown by the quarterback, [47] but they may also function as decoys or as blockers during running plays.

Tight ends line up outside the tackles and function both as receivers and as blockers. The role of the defense is to prevent the offense from scoring by tackling the ball carrier or by forcing turnovers interceptions or fumbles.

Defensive ends line up on the ends of the line, while defensive tackles line up inside, between the defensive ends.

The primary responsibilities of defensive ends and defensive tackles is to stop running plays on the outside and inside, respectively, to pressure the quarterback on passing plays, and to occupy the line so that the linebackers can break through.

Linebackers line up behind the defensive line but in front of the defensive backfield. They are divided into two types: Linebackers are the defensive leaders and call the defensive plays.

Their diverse roles include defending the run, pressuring the quarterback, and guarding backs, wide receivers and tight ends in the passing game. The defensive backfield , often called the secondary, consists of cornerbacks CB and safeties S.

Safeties are themselves divided into free safeties FS and strong safeties SS. Safeties are the last line of defense, and are responsible for stopping deep passing plays as well as running plays.

The special teams unit is responsible for all kicking plays. The special teams unit of the team in control of the ball will try and execute field goal FG attempts, punts and kickoffs , while the opposing team's unit will aim to block or return them.

Three positions are specific to the field goal and PAT point-after-touchdown unit: The long snapper's job is to snap the football to the holder, who will catch and position it for the placekicker.

There is not usually a holder on kickoffs, because the ball is kicked off of a tee; however, a holder may be used in certain situations, such as if wind is preventing the ball from remaining upright on the tee.

The player on the receiving team who catches the ball is known as the kickoff returner KR. The positions specific to punt plays are the punter P , long snapper, upback and gunner.

The long snapper snaps the football directly to the punter, who then drops and kicks it before it hits the ground.

Gunners line up split outside the line and race down the field, aiming to tackle the punt returner PR — the player that catches the punt.

Upbacks line up a short distance behind the line of scrimmage, providing additional protection to the punter. In American football, the winner is the team that has scored the most points at the end of the game.

There are multiple ways to score in a football game. The touchdown TD , worth six points, is the most valuable scoring play in American football.

A touchdown is scored when a live ball is advanced into, caught in, or recovered in the end zone of the opposing team. A PAT is most commonly attempted from the two- or three-yard line, depending on the level of play.

If scored by a placekick or dropkick through the goal posts, it is worth one point, and is typically called the extra point. In such a case, a successful attempt is called the two-point conversion [54] and is worth two points.

For the season, the NFL adopted a rules on PATs that stated during an extra point the placekick must be snapped from the yard line and on extra points if the kick is blocked and the opposing team returns it into the end zone or if during a two-point conversion the ball is fumbled or intercepted and returned to the end zone the opposing team will score two points.

No points are awarded on a failed extra point or two-point conversion attempt, although under a rare set of circumstances it is possible to score a safety, worth one point, if the defense takes the ball back into its own end zone and is downed there.

A field goal FG , worth three points, is scored when the ball is placekicked or dropkicked through the uprights and over the crossbars of the defense's goalposts.

A safety is scored when the ball carrier is tackled in their own end zone. Safeties are worth two points, which are awarded to the defense.

Lines marked along the ends and sides of the field are known respectively as the end lines and sidelines , and goal lines are marked 10 yards 9.

Weighted pylons are placed on the inside corner of the intersections of the goal lines and end lines.

White markings on the field identify the distance from the end zone. Inbound lines, or hash marks , are short parallel lines that mark off 1 yard 0.

Yard lines , which can run the width of the field, are marked every 5 yards 4. A one-yard-wide line is placed at each end of the field; this line is marked at the center of the two-yard line in professional play and at the three-yard line in college play.

Numerals that display the distance from the closest goal line in yards are placed on both sides of the field every ten yards.

Goalposts are located at the center of the plane of each of the two end lines. The crossbar of these posts is ten feet 3.

Goal posts are padded at the base, and orange ribbons are normally placed at the tip of each upright. The football itself is an oval ball, similar to the balls used in rugby or Australian rules football.

Football games last for a total of 60 minutes in professional and college play and are divided into two-halves of 30 minutes and four-quarters of 15 minutes.

The visiting team is allowed to call 'heads' or 'tails'; the winner of the toss is allowed to decide between choosing whether to receive or kick off the ball or choosing which goal they want to defend, but they can also defer their choice until the second half.

The losing team, unless the winning team decides to defer, is allowed to choose the option the winning team did not select, and receives the option to receive, kick, or select a goal to defend to begin the second half.

Most teams choose to receive or defer, because choosing to kick the ball to start the game would allow the other team to choose which goal to defend.

Games last longer than their defined length due to play stoppages — the average NFL game lasts slightly over three hours. An operator is responsible for starting, stopping and operating the game clock based on the direction of the appropriate official.

If the play clock expires before the ball has been snapped or free-kicked, a delay of game foul is called on the offense.

The play clock is set to 40 seconds in professional and college football and to 25 seconds in high school play or following certain administrative stoppages in the former levels of play.

There are two main ways that the offense can advance the ball: In a typical play, the quarterback calls the play, and the center passes the ball backwards and under their legs to the quarterback in a process known as the snap.

The quarterback then either hands the ball off to a back, throws the ball or runs with it. The play ends when the player with the ball is tackled or goes out of bounds, or a pass hits the ground without a player having caught it.

A forward pass can only be legally attempted if the passer is behind the line of scrimmage. The offense is given a series of four plays, known as downs.

If the offense advances ten or more yards in the four downs, they are awarded a new set of four downs. If they fail to advance ten yards, possession of the football is turned over to the defense.

In most situations, if the offense reaches their fourth down they will punt the ball to the other team, which forces them to begin their drive from further down the field; if they are in field goal range , they might also attempt to score a field goal.

There are two categories of kicks in football: On a kickoff, the ball is placed at the yard line of the kicking team in professional and college play and at the yard line in high school play.

The ball may be drop-kicked or place-kicked. If a place kick is chosen, the ball can be placed on the ground or on a tee, and a holder may be used in either case.

On a safety kick, the kicking team kicks the ball from their own yard line. They can punt, drop-kick or place-kick the ball, but a tee may not be used in professional play.

Any member of the receiving team may catch or advance the ball, and the ball may be recovered by the kicking team once it has gone at least ten yards and has touched the ground or has been touched by any member of the receiving team.

The three types of scrimmage kicks are place kicks, drop kicks, and punts. Only place kicks and drop kicks can score points.

If it is touched or recovered by the kicking team beyond this line, it becomes dead at the spot where it was touched. This prohibits the defense from blocking into or tackling the receiver, but the play ends as soon as the ball is caught and the ball may not be advanced.

Officials are responsible for enforcing game rules and monitoring the clock. All officials carry a whistle and wear black-and-white striped shirts and black hats except for the referee, whose hat is white.

Each carries a weighted yellow flag that is thrown to the ground to signal that a foul has been called. An official who spots multiple fouls will throw their hat as a secondary signal.

Another set of officials, the chain crew , are responsible for moving the chains. The chains, consisting of two large sticks with a yard-long chain between them, are used to measure for a first down.

The chain crew stays on the sidelines during the game, but if requested by the officials they will briefly bring the chains on to the field to measure.

A typical chain crew will have at least three people — two members of the chain crew will hold either of the two sticks, while a third will hold the down marker.

The down marker, a large stick with a dial on it, is flipped after each play to indicate the current down, and is typically moved to the approximate spot of the ball.

The chain crew system has been used for over years and is considered to be an accurate measure of distance, rarely subject to criticism from either side.

Football is a full-contact sport, and injuries are relatively common. Most injuries occur during training sessions, particularly ones that involve contact between players.

At a minimum players must wear a football helmet and a set of shoulder pads , but individual leagues may require additional padding such as thigh pads and guards, knee pads, chest protectors, and mouthguards.

The most common types of injuries are strains , sprains , bruises , fractures, dislocations , and concussions. Repeated concussions and possibly sub-concussive head impacts [] can increase a person's risk in later life for CTE chronic traumatic encephalopathy and mental health issues such as dementia , Parkinson's disease , and depression.

A study performed by the VA Boston Healthcare System and Boston University's school of medicine found that tackle football before age 12 was correlated with earlier onset of symptoms of CTE, but not with symptom severity.

More specifically, each year a player played tackle football under age 12 predicted earlier onset of cognitive, behavioral, and mood problems by an average of two and a half years.

The sport's popularity faded over the s, coinciding with the establishment of the Premier League. According to BBC America , there is a "social stigma" surrounding American football in the UK, with many Brits feeling the sport has no right to call itself 'football' due to the small emphasis on kicking.

But in these countries American football has not yet reached the same level of popularity it has, for example, in North America.

Brazil's audience is the 3rd of the world, behind only Mexico and United States. Rumors were that a Pro Bowl edition could be held there.

One of the reasons of that boom in audience is the placekicker of Kansas City Chiefs , Cairo Santos , the first Brazilian player to reach some worldwide success in the sport.

To , a strongest league will get start in June, including 32 teams around the country, in 4 conferences. The recent born team already won his state championship, and for the Brazilian top league already has signed with former NFL's player Nic Harris.

At the ends of the field there are scoring areas, called the end zones. There are also two yellow poles on the end of each field called uprights.

Sometimes, if the team can not score a touchdown they might want to kick it through the uprights for three points.

The uprights are also used for scoring one point after a team scored a touchdown. There are many types of players on a football team.

For the offensive part of the team, a quarterback throws the football to wide receivers while offensive linemen block to protect him from defensive players.

The offensive linemen also block when a running back runs to advance the football. Players on the Defensive line , a linebacker , and defensive backs cornerbacks and American football safeties attempt to tackle the offensive player who carries the football.

Some team members only play during certain times. These players belong to the Special Teams. The kicker can kick the ball to the other team or between the uprights, while the placeholder holds the ball steady.

The kick returner runs the ball down the field in an attempt to score points after catching the ball. A touchdown is achieved when a player has legal possession of the ball and the ball crosses an imaginary vertical plane above the opposing team's goal line.

After a touchdown, the scoring team attempts a try for 1 or 2 points see below. A successful touchdown is signaled by an official extending both arms vertically above the head.

A field goal is scored when the ball is place kicked between the goal posts behind the opponent's end zone. The most common type of kick used is the place kick.

For a place kick, the ball must first be snapped to a placeholder, who holds the ball upright on the ground with his fingertip so that it may be kicked.

Three points are scored if the ball crosses between the two upright posts and above the crossbar and remains over. Immediately following a touchdown, the scoring team can attempt to kick the ball between the goal posts for 1 extra point.

The team can also run or pass the ball into the end zone for 2 points. This is not done very often although it does happen. A safety is scored if a player causes the ball to become dead in his own end zone.

When this happens two points are awarded to the opposing usually defending team. This can happen if a player is either downed or goes out of bounds in the end zone while carrying the ball.

It can also happen if he fumbles the ball, and it goes out of bounds in the end zone. A safety is also awarded to the defensive team if the offensive team commits a foul which is enforced in its own end zone.

Exhibition season better known as Pre-Season is in August. In the exhibition season, the teams get ready for the regular season by having training.

Teams have practices to help the team get better and see who will make the team. All of the teams play 4 games before the regular season starts, and the games do not change what team gets to the post season.

Because of it, teams do not use their best players much, and use the games as more practice. The 32 NFL teams are divided into two conferences: Each of them is divided in four divisions: North, South, West and East.

Each division includes four teams. The season lasts 17 weeks. Each team plays 16 games and has one week off. This week of rest is called a "bye week".

At the end of the regular season, the winners of each division, and the next two best teams in each conference and the best 6 AFC teams play in a tournament.

The event is often treated as a National holiday as many stores close for the event.
