'''Volleyball''' is a [[team sport]] in which two teams of six players are separated by a net. Each team tries to score points by grounding a ball on the other team's court under organized rules.<ref>{{cite web |url=http://www.olympic.org/uk/sports/programme/index_uk.asp?SportCode=VB |title=Volleyball |access-date=2007-03-21 |publisher=[[International Olympic Committee]] |archive-date=March 23, 2018 |archive-url=https://web.archive.org/web/20180323031151/https://www.olympic.org/uk/sports/programme/index_uk.asp?SportCode=VB |url-status=live }}</ref> It has been a part of the official program of the [[Summer Olympic Games]] since [[1964 Summer Olympics|Tokyo 1964]]. [[Beach volleyball]] was introduced to the program at the [[1996 Summer Olympics|Atlanta 1996 Summer Olympics]]. The adapted version of volleyball at the [[Summer Paralympic Games]] is [[sitting volleyball]].

The team may touch the ball up to three times to return the ball to the other side of the court, but individual players may not touch the ball twice consecutively.<ref name=":1" /> Typically, the first two touches are used to set up for an attack. An attack is an attempt to direct the ball back over the net in such a way that the team receiving the ball is unable to pass the ball and continue the rally, thus, losing the point. The team that wins the rally is awarded a point and serves the ball to start the next rally. A few of the most common faults include:

* causing the ball to touch the ground or floor outside the opponents' court or without first passing over the net;
* catching and throwing the ball;
* double hit: two consecutive contacts with the ball made by the same player;
* four consecutive contacts with the ball made by the same team;
* net foul: touching the net during play;
* foot fault: the foot crosses over the boundary line when serving or under the net when a front row player is trying to keep the ball in play.

The ball is usually played with the hands or arms, but players can legally strike or push (short contact) the ball with any part of the body.<ref name=feet>Originally, only the upper body was allowed to touch the body and kicking the ball was penalised ({{Cite web|title=Can You Use Your Feet in Volleyball?: (What's the Rules)|date=4 October 2023|url=https://volleyballvault.com/can-you-use-your-feet-in-volleyball/|access-date=2023-12-07|publisher=volleyballvault.com|archive-date=December 7, 2023|archive-url=https://web.archive.org/web/20231207192345/https://volleyballvault.com/can-you-use-your-feet-in-volleyball/|url-status=live}}) In 1993 ([[Fédération Internationale de Volleyball|FIVB]]) and 1999 ([[National Collegiate Athletic Association|NCAA]], respectively, the rules were amended to allow for touching the ball with any part of the body.

A number of consistent [[#Skills|techniques]] have evolved in volleyball, including ''spiking'' and ''blocking'' (because those plays are made above the top of the net, the [[vertical jump]] is an athletic skill emphasized in the sport) as well as ''passing'', ''setting'', and specialized player positions. Offensive and defensive structures are also key plays.<ref>{{Cite web|title=History of Volleyball – NCVA|url=https://ncva.com/info/general-info/history-of-volleyball/|access-date=2021-04-29|publisher=ncva.com|archive-date=April 7, 2019|archive-url=https://web.archive.org/web/20190407203659/https://ncva.com/info/general-info/history-of-volleyball/|url-status=live}}</ref>

== History ==

=== Origins ===
{{Further|YMCA}}
[[File:William G. Morgan.jpg|thumb|[[William G. Morgan]] in {{Circa|1915}}]]
[[William G. Morgan]] invented the sport in 1895 while he was the [[YMCA]] physical education director in [[Holyoke, Massachusetts]].<ref>{{cite web |title=The International Association Training School Notes (vol. 4 no. 8), October, 1895 |url=https://cdm16122.contentdm.oclc.org/digital/collection/p16122coll3/id/389/ |url-status=live |archive-url=https://web.archive.org/web/20190602014956/https://cdm16122.contentdm.oclc.org/digital/collection/p16122coll3/id/389/ |archive-date=June 2, 2019 |access-date=May 31, 2018}}</ref> Because he originally derived the game from badminton, he initially named the sport ''mintonette''.<ref>{{cite web |date=2016-01-30 |title=In 1895, William Morgan Invents Mintonette |url=https://www.newenglandhistoricalsociety.com/1895-william-morgan-invents-mintonette/ |url-status=live |archive-url=https://web.archive.org/web/20180929075629/http://www.newenglandhistoricalsociety.com/15634-2/ |archive-date=September 29, 2018 |access-date=25 October 2021 |publisher=New England Historical Society |quote=Putting his mind to the challenge, Morgan examined the rules of sports such as [[baseball]], basketball, handball and badminton. Taking pieces from each, he created a game he called Mintonette. He took the name from badminton}}</ref> He was a one-time student of [[basketball]] inventor [[James Naismith]] and invented the game for his clients at the YMCA, most of whom were middle-aged businessmen for whom the physical demands of basketball were too great.<ref name=":2">{{Cite book |title=Berkshire encyclopedia of world sport |date=2005 |publisher=Berkshire Pub.

The first rules, written down by Morgan, called for a net {{convert|6|ft|6|in|m|abbr=on}} high, a {{convert|25|x|50|ft|m|abbr=on}} court, and any number of players. A match was composed of nine innings with three serves for each team in each inning, and no limit to the number of ball contacts for each team before sending the ball to the opponents' court. In case of a serving error, a second try was allowed. Hitting the ball into the net was considered a foul (with loss of the point or a side-out)—except in the case of the first-try serve.<ref name="ncva" />

After an observer, Alfred Halstead, noticed the volleying nature of the game at its first exhibition match in 1896, played at the International YMCA Training School (now called [[Springfield College]]), the game quickly became known as ''volleyball'' (it was originally spelled as two words: "''volley ball''{{-"}}). Volleyball rules were slightly modified by the International YMCA Training School and the game spread around the country to various YMCAs.<ref name="ncva">{{cite web|url=http://www.ncva.com/page.aspx?id=14 |title=How Volleyball Began |access-date=2007-09-21 |publisher=Northern California Volleyball Association |url-status=dead |archive-url=https://web.archive.org/web/20070701143054/http://www.ncva.com/page.aspx?id=14 |archive-date=July 1, 2007 }}</ref><ref name="FIVB Volleyball History">{{cite web |title=The Volleyball Story |url=http://www.fivb.com/EN/volleyball/story.htm |url-status=dead |archive-url=https://web.archive.org/web/20070127012658/http://www.fivb.com/EN/Volleyball/story.htm |archive-date=January 27, 2007 |access-date=2007-09-21 |publisher=Fédération Internationale de Volleyball (FIVB)}}</ref>

=== Volleyball in the Olympics ===
{{Main|Volleyball at the Summer Olympics}}
Volleyball has been part of the [[Summer Olympics]] program for both men and women consistently since [[1964 Summer Olympics|1964]].

== Rules of the game ==
[[File:VolleyballCourt.svg|thumb|A volleyball court]]
[[File:VolleyballRotation.svg|thumb|Rotation pattern]]

===Court dimensions ===
A volleyball court is {{convert|9|x|18|m||1|abbr=on}}, divided into equal square halves by a net with a width of {{convert|1|m|in|1|spell=in|sp=us}}.<ref name=":0">{{Cite encyclopedia|url=https://www.britannica.com/sports/volleyball|title=volleyball {{!}} Definition, Rules, Positions, & Facts|encyclopedia=Encyclopedia Britannica|access-date=2018-08-02|language=en|archive-date=April 7, 2023|archive-url=https://web.archive.org/web/20230407133923/https://www.britannica.com/sports/volleyball|url-status=live}}</ref> The top of the net is {{height|m=2.43|frac=16}} above the center of the court for men's competition, and {{height|m=2.24|frac=16}} for women's competition, varied for veterans and junior competitions.<ref name=":1" />

Typically in beach volleyball there is a playing area and a free zone area. The dimensions are 52’6” x 26’3” (including the free zone), and a minimum of 9’10 wide. The court includes 3 lines: net line, side line, and end line. In Beach volleyball scoring is similar to regular volleyball. 3 matches are being played.

The minimum height clearance for indoor volleyball courts is {{convert|7|m|ft|1|abbr=on}}, although a clearance of {{convert|8|m|ft|1|abbr=on}} is recommended.<ref name=":0" />

A line {{convert|3|m|ft|1|abbr=on}} from and parallel to the net is considered the "attack line". This "3 meter" (or "10-foot") line divides the court into "back row" and "front row" areas and the back court and front court.<ref name=":0" /> These are in turn divided into 3 areas each: these are numbered as follows, starting from area "1", which is the position of the serving player:

After a team gains the serve (also known as siding out), its members must rotate in a clockwise direction, with the player previously in area "2" moving to area "1" and so on, with the player from area "1" moving to area "6".<ref name=":1" /> Each player rotates only one time after the team gains possession of the service; the next time each player rotates will be after the other team wins possession of the ball and loses the point.<ref name=":0" />


The team courts are surrounded by an area called the free zone, which is at least 3 meters wide and may be entered and played within by the players after the service of the ball.<ref>{{cite book |title=Official Volleyball Rules 2017–2020 |publisher=FIVB |year=2016 |chapter=Section 1.1 |quote=The playing court is [...] surrounded by a free zone which is a minimum of 3&nbsp;m wide on all sides. |access-date=2019-02-05 |chapter-url=http://www.fivb.org/EN/Refereeing-Rules/documents/FIVB-Volleyball_Rules_2017-2020-EN-v06.pdf |archive-url=https://web.archive.org/web/20170205014730/http://www.fivb.org/EN/Refereeing-Rules/documents/FIVB-Volleyball_Rules_2017-2020-EN-v06.pdf |archive-date=2017-02-05 |url-status=live}}</ref> All lines marking the boundaries of the team court and the attack zone are drawn or painted within the dimensions of the area and are therefore part of the court or zone. If a ball touches a line, it is considered "in." An antenna is placed on each side of the net, perpendicular to the sideline, serving as a vertical extension of the side boundary of the court. A ball passing over the net must pass completely between the antennae (or their theoretical extensions to the ceiling) without contacting them.<ref name=":1" />

=== The ball ===
{{Main|Volleyball (ball)}}

[[FIVB]] regulations state that the ball must be spherical, made of leather or synthetic leather, have a circumference of {{Convert|65-67|cm|inch|abbr=on|1}}, a weight of {{Convert|260-280|g|oz|abbr=on}} and an interior air pressure of 0.30–0.325&nbsp;kg/cm<sup>2</sup> (4.26 to 4.61 psi; 294.3

Each team consists of six players.<ref name=":0" /> To get play started, a team is chosen to serve by [[coin toss]]. A player from the serving team throws the ball into the air and attempts to hit the ball so it passes over the net on a course such that it will land in the opposing team's court (the ''serve'').<ref name=":0" /> The opposing team must use a combination of no more than three contacts with the volleyball to return the ball to the opponent's side of the net.<ref name=":0" /> These contacts usually consist first of the ''bump'' or ''pass'' so that the ball's trajectory is aimed towards the player designated as the ''setter''; second of the ''set'' (usually an over-hand pass using wrists to push finger-tips at the ball) by the setter so that the ball's trajectory is aimed towards a spot where one of the players designated as an ''attacker'' can hit it, and third by the ''attacker'' who ''spikes'' (jumping, raising one arm above the head and hitting the ball so it will move quickly down to the ground on the opponent's court) to return the ball over the net.<ref name=":1" /> The team with possession of the ball that is trying to attack the ball as described is said to be on ''offence''.

The team on ''defence'' attempts to prevent the attacker from directing the ball into their court: players at the net jump and reach above the top (and if possible, across the plane) of the net to ''block'' the attacked ball.<ref name=":1" /> If the ball is hit around, above, or through the block, the defensive players arranged in the rest of the court attempt to control the ball with a ''dig'' (usually a fore-arm pass of a hard-driven ball). After a successful dig, the team transitions to offence.

The game continues in this manner, rallying back and forth until the ball touches the court within the boundaries or until an error is made.<ref name=":0" /> The most frequent errors that are made are either to fail to return the ball over the net within the allowed three touches, or to cause the ball to land outside the court.<ref name=":0" /> A ball is "in" if any part of it touches the inside of a team's court or a sideline or end-line, and a strong spike may compress the ball enough when it lands that a ball which at first appears to be going out may instead be in. Players may travel well outside the court to play a ball that has gone over a sideline or end-line in the air. A standard competitive volleyball match is played in a best-of-five sets format and typically goes on for about 90 minutes.<ref>{{Cite web |last=Brooks |first=Nathan |date=2024-02-14 |title=How Long is a Volleyball Game?: From High School Volleyball Game to Olympics 2024 - Infools |url=https://blog.infools.com/how-long-is-a-volleyball-game/ |access-date=2024-03-20 |language=en-US}}</ref>

Other common errors include a player touching the ball twice in succession, a player catching the ball, a player touching the net while attempting to play the ball, or a player penetrating under the net into the opponent's court. There are a large number of other errors specified in the rules, although most of them are infrequent occurrences. These errors include back-row or libero players spiking the ball or blocking (back-row players may spike the ball if they jump from behind the attack line), players not being in the correct position when the ball is served, attacking the serve in the front court and above the height of the net, using another player as a source of support to reach the ball, stepping over the back boundary line when serving, taking more than 8 seconds to serve,<ref>{{cite book |title=Official Volleyball Rules 2017–2020 |chapter-url=http://www.fivb.org/EN/Refereeing-Rules/documents/FIVB-Volleyball_Rules_2017-2020-EN-v06.pdf |access-date=2019-02-05 |year=2016 |publisher=FIVB|chapter=Section 12.4.4 |quote=The server must hit the ball within 8 seconds after the 1st referee whistles for service. |archive-url=https://web.archive.org/web/20170205014730/http://www.fivb.org/EN/Refereeing-Rules/documents/FIVB-Volleyball_Rules_2017-2020-EN-v06.pdf |archive-date=2017-02-05 |url-status=live }}</ref> or playing the ball when it is above the opponent's court.

=== Scoring ===
[[File:Mesa de anotadores de voleibol.jpg|thumb|A scorer's table shown just before a volleyball game]]
A point is scored when the ball contacts the floor within the court boundaries or when an error is made: when the ball strikes one team's side of the court, the other team gains a point; and when an error is made, the team that did not make the error is awarded a point, in either case paying no regard to whether they served the ball or not. If any part of the ball hits the line, the ball is counted as in the court. The team that won the point serves for the next point. If the team which won the point served in the previous point, the same player serves again. If the team that won the point did not serve the previous point, the players of the team acquiring the serve rotate their position on the court in a clockwise manner. The game continues, with the first team to score 25 points by a two-point margin awarded the set. Matches are best-of-five sets and the fifth set, if necessary, is usually played to 15 points. (Scoring differs between leagues, tournaments, and levels; high schools sometimes play best-of-three to 25; in the [[National Collegiate Athletic Association|NCAA]] matches are played best-of-five to 25 as of the [[2008 NCAA Division I women's volleyball tournament|2008]] season.)<ref name="ncaa.org">{{cite web |url=https://www.ncaa.org/wps/wcm/connect/resources/file/ebcecd09e29bb24/Summaryofchanges-final_post-PROP.pdf?MOD=AJPERES |title=2008 Major Rules-Change Proposals |access-date=2008-10-12 |date=2008-07-14 |work=ncaa.org |publisher=National Collegiate Athletic Association |archive-date=2021-08-14 |archive-url=https://web.archive.org/web/20210814044401/https://www.ncaa.org/wps/wcm/connect/resources/file/ebcecd09e29bb24/Summaryofchanges-final_post-PROP.pdf?MOD=AJPERES |url-status=dead }}</ref>

Before 1999, points could be scored only when a team had the serve (''side-out scoring'') and all sets went up to only 15 points. The FIVB changed the rules in 1999 (with the changes being compulsory in 2000) to use the current scoring system (formerly known as ''rally point system''), primarily to make the length of the match more predictable and to make the game more spectator- and television-friendly. The final year of side-out scoring at the [[NCAA Division I women's volleyball tournament|NCAA Division I Women's Volleyball Championship]] was [[2000 NCAA Division I women's volleyball tournament|2000]]. Rally point scoring debuted in [[2001 NCAA Division I women's volleyball tournament|2001]],<ref name="vsunewrl">{{cite news |url=https://news.google.com/newspapers?id=4ZhXAAAAIBAJ&pg=6990%2C2462398 |newspaper=Spokesman=Review |location=Spokane, Washington |last=Kraus |first=Hillary |title=Volleyball serves up new rules |date=August 25, 2001 |page=C7 |access-date=September 28, 2020 |archive-date=August 14, 2021 |archive-url=https://web.archive.org/web/20210814194212/https://news.google.com/newspapers?id=4ZhXAAAAIBAJ&pg=6990%2C2462398 |url-status=live }}</ref> and games were played to 30 points through [[2007 NCAA Division I women's volleyball tournament|2007]].

=== Libero ===
The libero player was introduced internationally in 1998,<ref>The term, meaning "free" in Italian, is pronounced LEE-beh-ro (although many players and coaches pronounce it lih-BEAR-oh).

When the ball is not in play, the libero can replace any back-row player, without prior notice to the officials. This replacement does not count against the substitution limit each team is allowed per set, although the libero may be replaced only by the player whom he or she replaced. Most U.S. high schools added the libero position from 2003 to 2005.<ref name=atmes/><ref name=tnknsas>{{cite news |url=https://news.google.com/newspapers?id=sxZUAAAAIBAJ&pg=3289%2C2152977 |newspaper=The Mirror |location=Tonganoxie, Kansas |last=Linenberger |first=Shawn|title=Volleyball players adjusting to libero role |date=October 5, 2005 |page=1B }}</ref>

The modern-day libero often takes on the role of a second setter. When the setter digs the ball, the libero is typically responsible for the second ball and sets to the front-row attacker. The libero may function as a setter only under certain restrictions. To make an overhand set, the libero must be standing behind (and not stepping on) the 3-meter line; otherwise, the ball cannot be attacked above the net in front of the 3-meter line. An underhand pass is allowed from any part of the court. The libero is generally the most skilled defensive player on the team. Additionally, there is a libero tracking sheet, where the referees or officiating team keep track of whom the libero substitutes in and out for.

Under FIVB rules, a libero is not allowed to serve. By contrast, a libero can serve in NCAA volleyball, but only in a specific rotation. That is, the libero can only serve for one person, not for all of the people for whom he or she goes in. That rule change was implemented in 2004 and applied to high school and junior high play soon after.

Under FIVB rules, each team can designate two liberos at the beginning of play, only one of whom can be on the court at any time, and each libero can serve in one specific rotation. This rule was implemented in NCAA women's volleyball, effective with the fall 2024 season.<ref>{{cite press release |url=https://www.ncaa.org/news/2024/2/20/media-center-double-contacts-approved-in-womens-volleyball.aspx |title=Double contacts approved in women's volleyball |publisher=NCAA |date=February 20, 2024 |access-date=February 24, 2024 |archive-date=February 24, 2024 |archive-url=https://web.archive.org/web/20240224002050/https://www.ncaa.org/news/2024/2/20/media-center-double-contacts-approved-in-womens-volleyball.aspx |url-status=live }}</ref>

=== Rule changes ===
Rule changes enacted in 2000 include allowing serves in which the ball touches the net, as long as it goes over the net into the opponents' court. Also, the service area was expanded to allow players to serve from anywhere behind the end line but still within the theoretical extension of the sidelines. Other changes were made to lighten up calls on faults for carries and double-touches, such as allowing multiple contacts by a single player ("double-hits") on a team's first contact provided that they are a part of a single play on the ball.<ref>{{Cite web |year=2021 |title=Official Volleyball Rules |url=https://www.fivb.com/wp-content/uploads/2024/03/FIVB-Volleyball_Rules_2021_2024_pe.pdf |publisher=37th FIVB World Congress, Buenos Aires, Argentina}}</ref>

In 2008, the NCAA changed the minimum number of points needed to win any of the first four sets from 30 to 25 for women's volleyball (men's volleyball remained at 30 for another three years, switching to 25 in 2011). If a fifth (deciding) set is reached, the minimum required score remains at 15. In addition, the word "game" is now referred to as "set".<ref name="ncaa.org" />

== Skills ==
Competitive teams master six basic skills: serve, pass, set, attack, block and dig.<ref name=":1" /> Each of the skills consists of a number of specific techniques which have been introduced over the years and are now considered standard practice in high-level volleyball.

=== Serve ===
[[File:Volleyball Sprungaufschlag.jpg|thumb|A player making a jump serve]]
[[File:Saque flotante en voleibol.ogv|thumb|A float serve]]
A player stands behind the inline and serves the ball in an attempt to drive it into the opponent's court. The main objective is to make it land inside the court; it is also desirable to set the ball's direction, speed and acceleration so that it becomes difficult for the receiver to handle it properly.<ref name=":1" /> A serve is called an "ace" when the ball either lands directly onto the opponent's court or the first opponent to touch the ball is unable to volley it (hit it upwards enough for a teammate to continue).

In contemporary volleyball, many types of serves are employed:
* Underhand: a serve in which the player strikes the ball below the waist instead of tossing it up and striking it with an overhand throwing motion. Underhand serves are considered very easy to receive and are rarely employed in high-level competitions.<ref name=":4">{{Cite web|title=The 5 Types of Serves in Volleyball You Must Know – Volleyball Expert|url=https://volleyballexpert.com/types-of-serves-in-volleyball/|access-date=2021-04-30|language=en-US|archive-date=April 30, 2021|archive-url=https://web.archive.org/web/20210430012426/https://volleyballexpert.com/types-of-serves-in-volleyball/|url-status=live}}</ref>
* Sky ball serve: a specific type of underhand serve occasionally used in [[beach volleyball]], where the ball is hit so high it comes down almost in a straight line. This serve was invented and employed almost exclusively by the Brazilian team in the early 1980s and is now considered outdated. During the [[2016 Summer Olympics|2016 Olympic Games in Rio de Janeiro]], however, the sky ball serve was extensively played by Italian [[beach volleyball]] player [[Adrian Carambula]]. In Brazil, this serve is called ''Jornada nas Estrelas'' (''[[Star Trek]]'').<ref>{{Cite web|title=What Is A Sky Ball In Volleyball? Definition & Meaning On SportsLingo|url=https://www.sportslingo.com/sports-glossary/s/sky-ball/|access-date=2021-05-01|website=www.sportslingo.com|language=en-US|archive-date=May 1, 2021|archive-url=https://web.archive.org/web/20210501141407/https://www.sportslingo.com/sports-glossary/s/sky-ball/|url-status=live}}</ref>
* Topspin: an overhand serve where the player tosses the ball high and hits it with a wrist snap, giving it topspin which causes it to drop faster than it would otherwise and helps maintain a straight flight path. Topspin serves are generally hit hard and aimed at a specific returner or part of the court. Standing topspin serves are rarely used above the high school level of play.<ref name=":4" />
* [[Volleyball float serve|Float]]: an overhand serve where the ball is hit with no spin so that its path becomes unpredictable, akin to a [[knuckleball]] in baseball.<ref name=":4" />
* Jump serve: an overhand serve where the ball is first tossed high in the air, then the player makes a timed approach and jumps to make contact with the ball, hitting it with much pace and topspin. This is the most popular serve among college and professional teams.<ref name=":4" />
* Jump float: an overhand serve where the ball is tossed high enough that the player may jump before hitting it similarly to a standing float serve. The ball is tossed lower than a topspin jump serve, but contact is still made while in the air. This serve is becoming more popular among college and professional players because it has a certain unpredictability in its flight pattern.<ref name=":4" />

=== Pass ===
[[File:Volleyball reception.jpg|thumb|A player making a forearm pass or bump]]
Also called reception, the pass is the attempt by a team to properly handle the opponent's serve or any form of attack. Proper handling includes not only preventing the ball from touching the court but also making it reach the position where the setter is standing quickly and precisely.<ref name=":1" />

The skill of passing involves fundamentally two specific techniques: underarm pass, or bump, where the ball touches the inside part of the joined forearms or platform, at waistline; and overhand pass, where it is handled with the fingertips, like a set, above the head.<ref name=":1" /> Either are acceptable in professional and [[beach volleyball]]; however, there are much tighter regulations on the overhand pass in beach volleyball. When a player passes a ball to their setter, it is ideal that the ball has relatively little spin to make it easier for the setter.

=== Set ===
[[File:Jump Set.jpg|thumb|Jump set]]
The set is usually the second contact that a team makes with the ball.<ref name=":1" /> The main goal of setting is to put the ball in the air in such a way that it can be driven by an attack into the opponent's court.<ref name=":1" /> The setter coordinates the offensive movements of a team, and is the player who ultimately decides which player will attack the ball.

As with passing, one can distinguish between an overhand set and a bump set. Since the former allows for more control over the speed and direction of the ball, the bump is used only when the ball is too low to be properly handled with the fingertips or in beach volleyball, where rules regulating overhand setting are more stringent. In the case of a set, one also refers to a front set or back set, indicating whether the ball is passed in the direction the setter is facing or behind them. There is also a jump set, used when the ball is too close to the net. In this case, the setter usually jumps off their right foot straight up to avoid going into the net. The setter typically stands about two-thirds of the way from the left to the right side of the net and faces left (the larger portion of the net visible to the setter).

Sometimes a setter refrains from raising the ball for a teammate to perform an attack and tries to play it directly onto the opponent's court. This movement is called a "dump".<ref>{{cite web |url=http://www.srcf.ucam.org/cuvc/club/glossary.php |title=Volleyball glossary |access-date=2007-03-20 |publisher=Cambridge University Volleyball Club |archive-date=2007-04-01 |archive-url=https://web.archive.org/web/20070401015838/http://www.srcf.ucam.org/cuvc/club/glossary.php |url-status=dead }}</ref> This can only be performed when the setter is in the front row, otherwise it constitutes an illegal back court attack. The most common dumps are to 'throw' the ball behind the setter or in front of the setter to zones 2 and 4. More experienced setters toss the ball into the deep corners or spike the ball on the second hit.

As with a set or an overhand pass, the setter/passer must be careful to touch the ball with both hands at the same time.<ref name=":1" /> If one hand is noticeably late to touch the ball this could result in a less effective set, as well as the referee calling a 'double hit' and giving the point to the opposing team.

=== Attack ===
{{See also|Volleyball offensive systems}}
[[File:Bilateral España-Portugal de voleibol - 02.jpg|thumb|A [[Spain men's national volleyball team|Spanish player]], #18 in a red outfit is shown about to spike towards the [[Portugal men's national volleyball team|Portuguese]] field, whose players are performing a block]]
The attack, also known as the ''spike'', is usually the third contact a team makes with the ball.<ref name=":1" /> The object of attacking is to handle the ball so that it lands on the opponent's court and cannot be defended.<ref name=":1" /> A player makes a series of steps (the "approach"), jumps, and swings at the ball.

Ideally, the contact with the ball is made at the apex of the hitter's jump. At the moment of contact, the hitter's arm is fully extended above their head and slightly forward, making the highest possible contact while maintaining the ability to deliver a powerful hit. The hitter uses arm swing, wrist snap, and a rapid forward contraction of the entire body to drive the ball.<ref name=":1" /> A 'bounce' is a slang term for a very hard/loud spike that follows an almost straight trajectory steeply downward into the opponent's court and bounces very high into the air. A "kill" is the slang term for an attack that is not returned by the other team thus resulting in a point.

Contemporary volleyball comprises a number of attacking techniques:<ref>{{Citation|last=Program|first=Uga Pedb|title=4. Attacking & Blocking|url=https://open.online.uga.edu/volleyball/chapter/attackingandblocking/|work=Ch.1 - Volleyball|language=en|access-date=2021-05-01|archive-date=May 1, 2021|archive-url=https://web.archive.org/web/20210501141449/https://open.online.uga.edu/volleyball/chapter/attackingandblocking/|url-status=live}}</ref>
* Backcourt (or back row): an attack performed by a back-row player. The player must jump from behind the 3-meter line before making contact with the ball, but may land in front of the 3-meter line. A Pipe Attack is when the center player in the back row attacks the ball.
* Line and Cross-court Shot: refers to whether the ball flies in a straight trajectory parallel to the sidelines, or crosses through the court in an angle. A cross-court shot with a very pronounced angle, resulting in the ball landing near the 3-meter line, is called a cut shot.
* Dip/Dink/Tip/Cheat/Dump: the player does not try to make a hit, but touches the ball lightly, so that it lands on an area of the opponent's court that is not being covered by the defence.
* Tool/Wipe/Block-abuse: the player does not try to make a hard spike, but hits the ball so that it touches the opponent's block and then bounces off-court.
* Off-speed hit: the player does not hit the ball hard, reducing its speed and thus confusing the opponent's defence.
* Quick hit/"One": an attack (usually by the middle blocker) where the approach and jump begin before the setter contacts the ball. The set (called a "quick set") is placed only slightly above the net and the ball is struck by the hitter almost immediately after leaving the setter's hands. Quick attacks are often effective because they isolate the middle blocker to be the only blocker on the hit.
* Slide: a variation of the quick hit that uses a low backset. The middle hitter steps around the setter and hits from behind him or her.
* Double quick hit/"Stack"/"Tandem": a variation of quick hit where two hitters, one in front and one behind the setter or both in front of the setter, jump to perform a quick hit at the same time. It can be used to deceive opposite blockers and free a fourth hitter attacking from back-court, maybe without block at all.

=== Block ===
[[File:Triple block (Serbia vs China, Grand Prix 2017).jpg|thumb|Three players performing a block, also known as a triple block]]
Blocking refers to the actions taken by players standing at the net to stop or alter an opponent's attack.<ref name=":1" /> A block which is aimed at completely stopping an attack, thus making the ball remain in the opponent's court, is called an offensive block. A well-executed offensive block is performed by jumping and reaching to penetrate with one's arms and hands over the net and into the opponent's area.<ref name=":1" /> It requires anticipating the direction the ball will go once the attack takes place.<ref name=":1" /> It may also require calculating the best footwork to executing the "perfect" block.

The jump should be timed so as to intercept the ball's trajectory prior to it crossing over the plane of the net. Palms are held deflected downward roughly 45–60 degrees toward the interior of the opponents' court. A "roof" is a spectacular offensive block that redirects the power and speed of the attack straight down to the attacker's floor as if the attacker hit the ball into the underside of a peaked house roof. By contrast, it is called a defensive, or "soft" block if the goal is to control and deflect the hard-driven ball up so that it slows down and becomes easier to defend. A well-executed soft-block is performed by jumping and placing one's hands above the net with no penetration into the opponent's court and with the palms up and fingers pointing backwards.

Blocking is also classified according to the number of players involved. Thus, there are single (or solo), double, and triple blocks.<ref name=":1" />

Successful blocking does not always result in a "roof" and many times does not even touch the ball. While it is obvious that a block was a success when the attacker is roofed, a block that consistently forces the attacker away from their 'power' or preferred attack into a more easily controlled shot by the defence is also a highly successful block. At the same time, the block position influences the positions where other defenders place themselves while opponent hitters are spiking.

=== Dig ===
[[File:Volleyball dig.jpg|thumb|A volleyball player preparing for a dig]]
Digging is the ability to prevent the ball from touching one's court after a spike or attack, particularly a ball that is nearly touching the ground.<ref name=":1" /> In many aspects, this skill is similar to passing, or bumping: overhand dig and bump are also used to distinguish between defensive actions taken with fingertips or with joined arms.<ref name=":1" /> It varies from passing, however, in that it is a much more reflex-based skill, especially at the higher levels. It is especially important while digging for players to stay on their toes; several players choose to employ a split step to make sure they are ready to move in any direction.

Some specific techniques are more common in digging than in passing. A player may sometimes perform a "dive", i.e., throw their body in the air with a forward movement in an attempt to save the ball, and land on their chest. When the player also slides their hand under a ball which is almost touching the court it is called a "pancake". The pancake is frequently used in indoor volleyball, but rarely if ever in beach volleyball because the uneven and yielding nature of the sand court limits the chances that the ball will make good, clean contact with the hand. When used correctly, it is one of the more spectacular defensive volleyball plays.

Sometimes a player may also be forced to drop their body quickly to the floor to save the ball. In this situation, the player makes use of a specific rolling technique to minimize the chances of injuries.

== Team play ==
[[File:U.S. Womens Volleyball team CISM 2007.jpg|thumb|The U.S. women's team huddling at the [[2007 Military World Games]]]]
Volleyball is essentially a game of transition from one of the above skills to the next, with choreographed team movement between plays on the ball. The team's movements are determined by the teams chosen serve receive system, offensive system, coverage system, and defensive system.

The serve-receive system is the formation used by the receiving team to attempt to pass the ball to the designated setter. Systems can consist of 5 receivers, 4 receivers, 3 receivers, and in some cases 2 receivers. The most popular formation at higher levels is a 3 receiver formation consisting of two left sides and a libero receiving every rotation. This allows middles and right sides to become more specialized at hitting and blocking. Offensive systems are the formations used by the offence to attempt to ground the ball into the opposing court (or otherwise score points). Formations often include designated player positions with skill specialization (see ''[[#Player specialization|Player specialization]]'', below). Popular formations include the 4–2, 6–2, and 5-1 systems (see ''[[#Formations|Formations]]'', below). There are also several different attacking schemes teams can use to keep the opposing defence off balance.

Coverage systems are the formations used by the offence to protect their court in the case of a blocked attack. Executed by the 5 offensive players not directly attacking the ball, players move to assigned positions around the attacker to dig up any ball that deflects off the block back into their own court. Popular formations include the 2-3 system and the 1-2-2 system. In lieu of a system, some teams just use a random coverage with the players nearest the hitter.

Defensive systems are formations used by the defense to prevent the ball from being grounded in their court by the opposing team. These systems outline which players are responsible for specific areas of the court depending on where the opposing team is attacking from. Popular systems include the 6-Up, 6-Back-Deep, and 6-Back-Slide defenses. Teams can also employ various blocking schemes to disrupt the opposing team’s offense. When one player is ready to serve, some teams line up their other five players in a screen to obscure the receiving team’s view. This action is only illegal if the server uses the screen, so the call is left to the referee’s discretion based on the screen’s impact on the receiving team’s ability to pass the ball. The most common screening style involves a W formation designed to take up as much horizontal space as possible.

== Strategy ==

[[Alessandro Fei (volleyball)|Alessandro Fei]] (#14) has no passing duties and is preparing for a back-row hit on the right side of the field.]]

=== Player specialization ===
There are five positions filled on every volleyball team at the elite level: setter, outside hitter (left-side hitter), middle hitter (middle blocker), opposite hitter (right-side hitter) and libero / defensive specialist. Each of the positions plays a specific, key role in winning a volleyball match.
* '''Setters''' have the task for orchestrating the offence of the team. They aim for the second touch and their main responsibility is to place the ball in the air where the attackers can place the ball into the opponents' court for a point. They have to be able to operate with the hitters, manage the tempo of their side of the court and choose the right attackers to set. Setters need to have a swift and skillful appraisal and tactical accuracy and must be quick at moving around the court. At elite level, setters used to usually be the shortest players of a team (before liberos were introduced), not being typically required to perform jump hits, but that would imply need for short-term replacement by taller bench players when critical points required more effective blocks; in the 1990s taller setters (e.g. [[Fabio Vullo]], [[Peter Blangé]]) began being deployed, in order to improve blocks.
* '''Liberos''' are defensive players who are responsible for receiving the attack or serve. They are usually the players on the court with the quickest reaction time and best passing skills. ''Libero'' means 'free' in [[Italian language|Italian]]—they receive this name as they have the ability to substitute for any other player on the court during each play (usually the middle blocker). Liberos are not permitted to block or perform attacks, meaning they never play at the net, which allows shorter players with strong passing and defensive skills to excel in the position and play an important role in the team's success. A player designated as a libero for a match may not play other roles during that match. Liberos wear a different colour jersey than their teammates.<ref>{{Cite web |last=Chesaux |first=Samuel |title=FIVB Official Volleyball Rules 2015-2016 |url=https://www.volleyball.com/wp-content/uploads/2016/05/FIVB-Volleyball-Rules-2015-2016-EN-V3-20150205.pdf |access-date=January 28, 2023 |archive-date=January 29, 2023 |archive-url=https://web.archive.org/web/20230129004323/https://www.volleyball.com/wp-content/uploads/2016/05/FIVB-Volleyball-Rules-2015-2016-EN-V3-20150205.pdf |url-status=live }}</ref>
* '''Middle hitters''', or '''middle blockers''', are players that can perform very fast attacks that usually take place near the setter. They are specialized in blocking since they must attempt to stop equally fast plays from their opponents and then quickly set up a double block at the sides of the court. In non-beginners play, every team will have two middle hitters. At elite levels, middle hitters are usually the tallest players, whose limited agility is countered by their height enabling more effective blocks.
* '''Outside hitters''', or '''left-side hitters''', attack from near the left antenna. The outside hitter is usually the most consistent hitter on the team and gets the most sets. Inaccurate first passes usually result in a set to the outside hitter rather than middle or opposite. Since most sets to the outside are high, the outside hitter may take a longer approach, always starting from outside the court sideline. In non-beginners play, there are again two outside hitters on every team in every match. At elite level, outside hitters are slightly shorter than middle hitters and opposite hitters, but have the best defensive skills, therefore always re-placing to the middle while in the back row.
* '''Opposite hitters''', or '''right-side hitters''', carry the defensive workload for a volleyball team in the front row. Their primary responsibilities are to put up a well-formed block against the opponents' ''Outside hitters'' and serve as a backup setter. Sets to the opposite usually go to the right side of the antennae. Therefore, they are usually the most technical hitters since balls lifted to the right side are quicker and more difficult to handle (the setters having to place the ball while slightly off-set to the right, and with their back to the attacker), and also having to jump from the back row when the setter is on the front row. At elite level, until the 1990s several opposite hitters used to be able to also play as middle hitters (e.g. [[Andrea Zorzi]], [[Andrea Giani]]), before high specialization curtailed this flexibility in the role.<ref>{{cite web |title=Volleyball Information: History, Facts & Volleyball Rules 2023 |date=31 December 2022 |url=https://sportycious.com/volleyball-information-91251/ |access-date=2023-09-02 |publisher=Sportycious |archive-date=September 4, 2023 |archive-url=https://web.archive.org/web/20230904123715/https://sportycious.com/volleyball-information-91251/ |url-status=live }}</ref>

At some levels where substitutions are unlimited, teams will make use of a '''defensive specialist''' in place of or in addition to a libero. This position does not have unique rules like the libero position, instead, these players are used to substitute out a poor back row defender using regular substitution rules. A defensive specialist is often used if you have a particularly poor back court defender in right side or left side, but your team is already using a libero to take out your middles. Most often, the situation involves a team using a right-side player with a big block who must be subbed out in the back row because they are not able to effectively play backcourt defence. Similarly, teams might use a serving specialist to sub out a poor server.

=== Formations ===
The three standard volleyball formations are known as "4–2", "6–2" and "5–1", which refers to the number of hitters and setters respectively. 4–2 is a basic formation used only in beginners' play, while 5–1 is by far the most common formation in high-level play.

==== 4–2 ====
The 4–2 formation has four hitters and two setters. The setters usually set from the middle front or right front position. The team will, therefore, have two front-row attackers at all times. In the international 4–2, the setters set from the right front position. The international 4–2 translates more easily into other forms of offence. The setters line up opposite each other in the rotation. The typical lineup has two outside hitters. By aligning like positions opposite themselves in the rotation, there will always be one of each position in the front and back rows. After service, the players in the front row move into their assigned positions, so that the setter is always in the middle front. Alternatively, the setter moves into the right front and has both a middle and an outside attacker; the disadvantage here lies in the lack of an offside hitter, allowing one of the other team's blockers to "cheat in" on a middle block.

The clear disadvantage with this offensive formation is that there are only two attackers, leaving a team with fewer offensive weapons.

Another aspect is to see the setter as an attacking force, albeit a weakened force, because when the setter is in the frontcourt they are able to 'tip' or 'dump', so when the ball is close to the net on the second touch, the setter may opt to hit the ball over with one hand. This means that the blocker who would otherwise not have to block the setter is engaged and may allow one of the hitters to have an easier attack.

==== 6–2 ====
In the 6–2 formation, a player always comes forward from the back row to set. The three front row players are all in attacking positions. As a result all six players act as hitters at one time or another, while two can act as setters. So the 6–2 formation is now a 4–2 system, but the back-row setter penetrates to set. The 6–2 lineup thus requires two setters, who line up opposite to each other in the rotation. In addition to the setters, a typical lineup will have two middle hitters and two outside hitters. By aligning like positions opposite themselves in the rotation, there will always be one of each position in the front and back rows. After service, the players in the front row move into their assigned positions.

The advantage of the 6–2 is that there are always three front-row hitters available, maximizing the offensive possibilities. However, not only does the 6–2 require a team to possess two people capable of performing the highly specialized role of setter, it also requires both of those players to be effective offensive hitters when not in the setter position. At the international level, only the [[Cubans|Cuban]] National Women's Team employs this kind of formation. It is also used by [[National Collegiate Athletic Association|NCAA]] teams in [[NCAA Division III|Division III]] men's play and women's play in all divisions, partially due to the variant rules used which allow more substitutions per set than the 6 allowed in the standard rules—12 in matches involving two Division III men's teams<ref>{{cite web|url=https://www.ncaa.org/sites/default/files/2015-17_MVB_Rules_Modification_20170104.pdf |title=NCAA Men's Volleyball 2015–17 Rules Modifications |publisher=NCAA |date=August 1, 2016 |access-date=August 16, 2017 |archive-url=https://web.archive.org/web/20170817000735/https://www.ncaa.org/sites/default/files/2015-17_MVB_Rules_Modification_20170104.pdf |archive-date=August 17, 2017 |url-status=dead }} Note that if a Division III team is playing a team in the National Collegiate division (Division I or II), the FIVB limit of 6 substitutions per set is enforced.</ref> and 15 for all women's play.<ref>{{cite book |url=http://www.ncaapublications.com/productdownloads/VBR17.pdf |chapter=Rule 11.3.2: Substitutions – Limitations |title=Women's Volleyball 2016 and 2017 Rules and Interpretations |page=42 |publisher=NCAA |access-date=August 16, 2017 |archive-url=https://web.archive.org/web/20170806073756/http://www.ncaapublications.com/productdownloads/VBR17.pdf |archive-date=August 6, 2017 |url-status=live }}</ref>

==== 5–1 ====
The 5–1 formation has only one player who assumes setting responsibilities regardless of their position in the rotation. The team will, therefore, have three front-row attackers when the setter is in the back row and only two when the setter is in the front row, for a total of five possible attackers.

The player opposite the setter in a 5–1 rotation is called the ''opposite hitter''. In general, opposite hitters do not pass; they stand behind their teammates when the opponent is serving. The opposite hitter may be used as a third attack option (back-row attack) when the setter is in the front row: this is the normal option used to increase the attack capabilities of modern volleyball teams. Normally the opposite hitter is the most technically skilled hitter of the team. Back-row attacks generally come from the back-right position, known as zone 1, but are increasingly performed from back-centre in high-level play.

The big advantage of the system is that the setter always has 3 hitters with which to vary sets. If the setter performs well, the opponent's middle blocker may not have enough time to block with the outside blocker, increasing the chance for the attacking team to make a point.

There is another advantage, the same as that of a 4–2 formation: as a front-row player the setter is allowed to jump and "dump" the ball onto the opponent's side. Thus the setter can confuse the opponent's blocking players; they have the option to jump and dump or set to one of the hitters. A good setter knows and they are able to jump to dump or to set for a quick hit as well as when setting outside, thus they are able to confuse the opponent.

The 5–1 offence is a mix of 6–2 and 4–2: when the setter is in the front row, the offense looks like a 4–2; when the setter is in the back row, the offense looks like a 6–2.

[[File:Beach volley at Hietsu 2013.jpg|thumb|[[Beach volleyball]] at the [[Hietaniemi Beach]] in [[Helsinki|Helsinki, Finland]]]]
There are many variations on the basic rules of volleyball. By far the most popular of these is [[beach volleyball]], which is played on sand with two people per team and rivals the main sport in popularity.

Some games related to volleyball include:
* [[Crossnet]]: a four-way volleyball game, combining volleyball and foursquare.
* [[9-man]]: A variant invented by Chinese immigrants to the United States in the 1930s. 9-man is still played in Asian countries and North America, being recognized for its historic and cultural significance. In 2014, a [[9-Man (film)|documentary]] was produced about the sport,<ref>{{Cite web |title=9-Man (2014) |url=https://www.imdb.com/title/tt2986300/ |access-date=March 10, 2025 |website=IMDb}}</ref> and a YouTube documentary was made in 2017.{{citation needed|date=February 2022}}
* Beachball volleyball: A game of indoor volleyball played with a [[beach ball]] instead of a volleyball.
* [[Biribol]]: an aquatic variant, played in shallow swimming pools. The name comes from the Brazilian city where it was invented, [[Birigui]]. It is similar to [[water volleyball]].
* [[Ecua-volley]]: A variant invented in Ecuador, with some significant variants, such as number of players, and a heavier ball.
* [[Footvolley]]: A sport from Brazil in which the hands and arms are not used, but it is otherwise similar to beach volleyball.
* [[Hooverball]]: Popularized by President [[Herbert Hoover]], it is played with a volleyball net and a [[medicine ball]]; it is scored like tennis, but the ball is caught and then thrown back. The weight of the medicine ball can make the sport physically demanding for players; annual championship tournaments are held in [[West Branch, Iowa]].
* [[Newcomb ball]] (sometimes spelled "Nuke 'Em"): In this game, the ball is caught and thrown instead of hit; it rivaled volleyball in popularity until the 1920s.
** Prisoner Ball: Also played with volleyball court and a volleyball, prisoner ball is a variation of [[Newcomb ball]] where players are "taken prisoner" or released from "prison" instead of scoring points. This version is usually played by young children.<ref name="pribook">{{cite book | url=https://books.google.com/books?id=Z2EgTLpHfxEC&q=prisoner+ball+volleyball&pg=PA168 | title=Games For Youth Groups | publisher=Youth Specialties | access-date=August 26, 2012| isbn=9780310220305 | year=1997 }}</ref>
