Volleyball is an Olympic team sport in which two teams of 6 active players (5 normal players and one 'libero'), are separated by a net that is usually four feet. Each team tries to score points against one another by grounding a ball on the other team's court under organized rules.
The complete rules of volleyball are extensive, and points are awarded as follows: If the ball touches the ground outside the court area, the team which made contact with it last loses the point. If the ball touches the ground on team A's side of the net, team B is awarded a point, and vice-versa. The ball must be hit over the net to get a point.The team who wins the point then serves. The first team to reach 25 points wins the set and the first team to win three sets wins the match. Teams can contact the ball only three times before the ball crosses the net, and consecutive contacts must be made by different players. 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.
Through time, volleyball has developed to involve common techniques of spiking, passing, blocking, and setting, as well as specialized player positions and offensive and defensive structures. Because many plays are made above the top of the net, vertical jumping is an athletic skill emphasised in volleyball. This article focuses on competitive indoor volleyball, which is carefully regulated and played indoors. Numerous variations of volleyball have developed for casual play, including the Olympic spin-off sport beach volleyball.
Origin of volleyball
On February 9, 1895, in Holyoke, Massachusetts
(USA), William G Morgan
, a YMCA
physical education director, created a new game called Mintonette
as a pastime to be played preferably indoors and by any number of players. The game took some of its characteristics from tennis
. Another indoor sport, basketball
, was catching on in the area, having been invented just ten miles (sixteen kilometers) away in the city of Springfield, Massachusetts
, only four years before. Mintonette (as volleyball was then known) was designed to be an indoor sport less rough than basketball for older members of the YMCA, while still requiring a bit of athletic effort.
The first rules, written down by William G Morgan, called for a net 6 ft 6 in (1.98 m) high, a 25×50 ft² (7.6×15.2 m²) 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.
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.
Refinements and later developments
The first official ball used in volleyball is disputed; some sources say that Spalding created the first official ball in 1896, while others claim it was created in 1900. The rules have evolved over time; by 1916, the skill and power of the set and spike had been introduced, and four years later a "three hits" rule and back row hitting guidelines were established. In 1917, the game was changed from 21 to 15 points. In 1919, about 16,000 volleyballs were distributed by the American Expeditionary Forces
to their troops and allies
, which sparked the growth of volleyball in new countries.
The first country outside the United States to adopt volleyball was Canada in 1900. An international federation, the Fédération Internationale de Volleyball (FIVB), was founded in 1947, and the first World Championships were held in 1949 for men and 1952 for women. The sport is now popular in Brazil, in Europe (where especially Italy, the Netherlands, and countries from Eastern Europe have been major forces since the late 1980s), in Russia, and in other countries including China and the rest of Asia, as well in as the United States.
Beach volleyball, a variation of the game played on sand and with only two players per team, became a FIVB-endorsed variation in 1987 and was added to the Olympic program at the 1996 Summer Olympics.
Volleyball in the Olympics
The history of Olympic volleyball can be traced back to the 1924 Summer Olympics
, where volleyball was played as part of an American sports demonstration event. After the foundation of FIVB and some continental confederations, it began to be considered for official inclusion. In 1957, a special tournament was held at the 53rd IOC
session in Sofia, Bulgaria
to support such request. The competition was a success, and the sport was officially included in the program for the 1964 Summer Olympics
The Olympic volleyball tournament was originally a simple competition, whose format paralleled the one still employed in the World Cup: all teams played against each other team and then were ranked by wins, set average, and point average. One disadvantage of this round-robin system is that medal winners could be determined before the end of the games, making the audience lose interest in the outcome of the remaining matches. To cope with this situation, the competition was split into two phases with the addition of a "final round" elimination tournament consisting of quarterfinals, semifinals, and finals matches in 1972. The number of teams involved in the Olympic tournament has grown steadily since 1964. Since 1996, both men's and women's events count twelve participant nations. Each of the five continental volleyball confederations has at least one affiliated national federation involved in the Olympic Games.
The U.S.S.R. won men's gold in both 1964 and 1968. After taking bronze in 1964 and silver in 1968, Japan finally won the gold for men's volleyball in 1972. Women's gold went to Japan in 1964 and again in 1976. That year, the introduction of a new offensive skill, the backrow attack, allowed Poland to win the men's competition over the Soviets in a very tight five-set match. Since the strongest teams in men's volleyball at the time belonged to the Eastern Bloc, the American-led boycott of the 1980 Summer Olympics did not have as great an effect on these events as it had on the women's. The U.S.S.R. collected their third Olympic Gold Medal in men's volleyball with a 3-1 victory over Bulgaria (the Soviet women won that year as well, their third gold as well). With the U.S.S.R. boycotting the 1984 Olympic Games in Los Angeles, the U.S. was able to sweep Brazil in the finals to win the men's gold medal. Italy won its first medal (bronze in the men's competition) in 1984, foreshadowing a rise in prominence for their volleyball teams.
At the 1988 Games, Karch Kiraly and Steve Timmons led the U.S. men's team to a second straight gold medal. In 1992, underrated Brazil upset favourites C.I.S., Netherlands, and Italy in the men's competition for the country's first Olympic gold medal. Runner-up Netherlands, men's silver medalist in 1992, came back under team leaders Ron Zwerver and Olof van der Meulen in the 1996 Games for a five-set win over Italy. A men's bronze medalist in 1996, Serbia and Montenegro (playing in 1996 and 2000 as the Federal Republic of Yugoslavia) beat Russia in the gold medal match in 2000, winning their first gold medal ever. In 2004, Brazil won its second men's volleyball gold medal beating Italy in the finals. In the 2008 Games, the USA beat Brazil in the men's volleyball final.
Rules of the game
The game is played on a volleyball court 18 meters long and 9 meters wide, divided into two 9 m × 9 m halves by a one-meter wide net placed so that the top of the net is 2.43 meters above the center of the court for men's competition, and 2.24 meters for women's competition (these heights are varied for veterans and junior competitions).
There is a line 3 meters from and parallel to the net in each team court which is considered the "attack line". This "3 meter" (or 10 foot) line divides the court into "back row" and "front row" areas (also back court and front court). 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" (see also the Errors and faults section).
The team courts are surrounded by an area called the free zone which is a minimum of 3 meters wide and which the players may enter and play within after the service of the ball. All lines denoting the boundaries of the team court and the attack zone are drawn or painted within the dimensions of the area and are therefore a part of the court or zone. If a ball comes in contact with the line, the ball is considered to be "in". An antenna is placed on each side of the net perpendicular to the sideline and is 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.
The volleyball is made of leather or synthetic leather and inflated according to FIVB regulations:
- *Its circumference is 65–67 cm and its weight is 260–280 g.
- *Its inside pressure shall be 0.30–0.325 kg/cm2 (4.26–4.61 psi, 294.3–318.82 mbar or hPa).
Each team consists of six players. To get play started, a team is chosen to serve by coin toss
. A player from the serving team (generally accepted to have the advantage inplay) 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
). 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. These contacts usually consist first of the bump
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
(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. The team with possession of the ball that is trying to attack the ball as described is said to be on offense
The team on defense 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 in order to block the attacked ball. 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 offense.
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.
Errors and faults
- The ball lands out of the court, in the same court as the team that touched it last, under the net to the opposing team's court, or the ball touches the net "antennas." The ball also may not pass over or outside the antennas even if it lands in the opponents' court.1
- The ball is touched more than three times before being returned to the other team's court.2
- The same player touches the ball twice in succession.3
- A player "lifts" or "carries" the ball (the ball remains in contact with the player's body for too long).
- A player touches the net with any part of his or her body or clothing while making a play on the ball (with the exception of the hair).
- The players of one team do not manage to touch the ball before the ball lands in their half of the court.
- A back-row player spikes the ball while it is completely above the top of the net, unless he or she jumped from behind the attack line (the player is, however, allowed to land in front of the attack line).
- A back-row player participates in a completed block of the opposing team's attack (completed means at least one blocker touched the ball).
- The libero, a defensive player who can only play in the back row, attempts a block or makes an "attack hit" (defined as any action which directs the ball towards the opponents, with the exception of service and block) while the ball is entirely higher than the top of the net.
- A player completes an attack hit from higher than the top of the net when the ball is coming from an overhand finger pass (set) by a libero in the front zone.
- A player is not in the correct position at the moment of serve, or serves out of turn. This type of foul is related to the position currently occupied by the players (see the table in the Equipment section). When ball is served, players can place themselves freely on the field (e.g. a "back-row" player can be close to the net) so long as they obey the following rules: The area "1" player must be behind the area "2" player and to the right of the area "6" player. The area "6" player must be behind area "3" player, to the left of area "1" player and to the right of area "5". The area "5" player must be behind the area "4" player and to the left of the area "6" player. Symmetric rules must be respected by the front-row players (those in areas "2", "3" and "4"). The penalty for being out of rotation is an automatic service ace if the opposing team is serving, and if it's on the serving team sides, it's an automatic turnover.
- When hitting, a player makes contact with the ball in the space above the opponent's court (in blocking an attack hit, this is allowed).
- A player touches the opponent's court with any part of his or her body except the feet or hands.4
- When serving, a player steps on the court or the end line before making contact with the ball.
- A player takes more than 8 seconds to serve.
- At the moment of serve, one or more players jump, raise their arms or stand together at the net in an attempt to block the sight of the ball from the opponent (screening).5
- A player blocks the serve or attacks the serve when the ball is in the front zone and above the top of the net.
- There is a physical fight between players, whether an opponent or on the same team
- 1 If the ball passes outside the antennas on the first contact for the team, e.g. as the result of a bad pass or dig, a player is allowed to go after the ball as long as he or she does not touch the opponent's court and the ball travels back to his or her team's court also outside the antennas.
- 2 Except if a player blocks (touches a ball sent over the net by the opposing team, while reaching above the top of the net) a ball that stays in the blocker's side of the net. In such an instance the blocker may play the ball another time without violating the rule against playing the ball twice in succession. If the ball is touched during a block, that contact is not considered one of the team's three contacts.
- 3 At the first hit of the team, the ball may contact various parts of the body consecutively provided that the contacts occur during one action. Also, when a player touches the ball on a block, he or she may make another play on the ball.
- 4 Penetration under the net with hands or feet is allowed only if a portion of the penetrating hands or feet remains in contact with or directly above the player's court or center line.
- 5 Screening is only a fault if the players stand directly next to each other in a way that clearly impedes vision, and the serve is a low line drive over their heads. (This is a judgment call by the referee. Teams are generally given a warning before being sanctioned for screening.)
When the ball contacts the floor within the court boundaries or an error is made, the team that did not make the error is awarded a point, whether they served the ball or not. The team that won the point serves for the next point. If the team that 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 rotate their position on the court in a clockwise manner. The game continues, with the first team to score 25 points (and be two points ahead) 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 30; in the NCAA
games are played best-of-five to 25.)
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.
In 1998 the libero player was introduced internationally, the term meaning free
in Italian is pronounced LEE-beh-ro (rather than lih-BEAR-oh); the NCAA introduced the libero in 2002. The libero is a player specialized in defensive skills: the libero must wear a contrasting jersey color from his or her teammates and cannot block or attack the ball when it is entirely above net height. 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 they replaced.
The libero may function as a setter only under certain restrictions. If she/he makes an overhand set, she/he 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. There is also a libero tracking sheet, where the referees or officiating team must keep track of who the libero subs in and out for. There may only be one libero per set (game), although there may be a different libero in the beginning of any new set (game).
Furthermore, a libero is not allowed to serve, according to international rules, with the exception of the NCAA women's volleyball games, where a 2004 rule change allows the libero to serve, but only in a specific rotation. That is, the libero can only serve for one person, not for all of the people for whom she goes in. That rule change was also applied to high school and junior high play soon after.
Recent rule changes
Other 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.
On February 28, 2008, the NCAA changed collegiate scoring from 30 to 25. If the match goes to 3 sets, the required score would still be 15 to win. In addition, the word "game" is now referred to as "set".
Competitive teams master six basic skills: serve, pass, set, attack, block and dig. Each of these skills comprises a number of specific techniques that have been introduced over the years and are now considered standard practice in high-level volleyball.
A player stands behind the inline and serves the ball, in an attempt to drive it into the opponent's court. His or her main objective is to make it land outside 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. A serve is called an "ace" when the ball lands directly onto the court or travels outside the court after being touched by an opponent.
In contemporary volleyball, many types of serves are employed:
- Underhand and Overhand Serve: refers to whether the player strikes the ball from below, at waist level, or first tosses the ball in the air and then hits it above shoulder level. Underhand serve is considered very easy to receive and is rarely employed in high-level competitions.
- 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. In Brazil, this serve is called Jornada nas Estrelas (Star Trek).
- Line and Cross-Court Serve: refers to whether the ball flies in a straight trajectory parallel to the side lines, or crosses through the court in an angle.
- Top Spin: an overhand serve where the ball gains topspin through wrist snapping. This spin causes the ball to drop fast.
- Floater: an overhand serve where the ball is hit with no spin so that its path becomes unpredictable. This type of serve can be administered while jumping or standing. This is akin to a curveball in baseball.
- 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. There is usually much topspin imparted on the ball. This is the least popular serve amongst college and professional teams. In Brazil, this serve is called Viagem ao Fundo do Mar (Voyage to the Bottom of the Valley), like an antithesis to the Star Trek serve.
- Jump Float: This is a serve like the jump serve and the floater. 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 amongst college and professional players because it has a certain unpredictability in its flight pattern.
- Round-House Serve: the player stands with one shoulder facing the net, tosses the ball high and hits it with a fast circular movement of the arm. The ball is hit with the palm of the hand, creating a lot of topspin.
- Hybrid Serve: An overhand serve delivered similarly to a top spin serve; however, it has more pace than a floater, but has a similar unpredictable path.
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.
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 waist line; and overhand pass, where it is handled with the fingertips, like a set, above the head. Either form (joined forearm or overhand pass) are acceptable in professional and beach volleyball.
The set is usually the second contact that a team makes with the ball. 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. The setter coordinates the offensive movements of a team, and is the player who ultimately decides which player will actually attack the ball.
As with passing, one may distinguish between an overhand 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 so low it cannot be properly handled with fingertips, or in beach volleyball where rules regulating overhand setting are more stringent. In the case of a set, one also speaks of a front or back set, meaning whether the ball is passed in the direction the setter is facing or behind the setter. There is also a jump set that is used when the ball is too close to the net. In this case the setter usually jumps off his or her right foot straight up to avoid going into the net. The setter usually stands about ⅔ of the way from the left to the right of the net and faces the left (the larger portion of net that he or she can see).
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". 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.
The attack (or spike, the slang term) is usually the third contact a team makes with the ball. The object of attacking is to handle the ball so that it lands on the opponent's court and cannot be defended. 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 his or her 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. 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:
- Backcourt (or backrow)/pipe attack: 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.
- Line and Cross-court Shot: refers to whether the ball flies in a straight trajectory parallel to the side lines, 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: 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 defense.
- 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 acceleration and thus confusing the opponent's defense.
- 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 back set. 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 backcourt, maybe without block at all.
- Kill- when someone scores a point and touches the ball.
- Ace- when someone scores a point immediately off the serve.
Blocking refers to the actions taken by players standing at the net to stop or alter an opponent's attack.
A block that is aimed at completely stopping an attack, thus making the ball remain in the opponent's court, is called offensive. 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. It requires anticipating the direction the ball will go once the attack takes place. It may also require calculating the best foot work to executing the "perfect" block.
The jump should be timed so as to intercept the ball's trajectory prior to it crossing over the net. Palms are held deflected downward about 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 more easy to be defended. 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 backward.
Blocking is also classified according to the number of players involved. Thus, one may speak of single (or solo), double, or triple block.
Successful blocking does not always result in a "roof" and many times does not even touch the ball. While it’s obvious that a block was a success when the attacker is roofed, a block that consistently forces the attacker away from his or her 'power' or preferred attack into a more easily controlled shot by the defense 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.
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. 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.
Some specific techniques are more common in digging than in passing. A player may sometimes perform a "dive", i.e., throw his or her body in the air with a forward movement in an attempt to save the ball, and land on his or her chest. When the player also slides his or her hand under a ball that is almost touching the court, this is called a "pancake". The pancake is frequently used in indoor volleyball.
Sometimes a player may also be forced to drop his or her body quickly to the floor in order to save the ball. In this situation, the player makes use of a specific rolling technique to minimize the chances of injuries.
for volleyball can be classified under two main categories: match coaching and developmental coaching. The objective of match coaching is to win a match by managing a team's strategy. Developmental coaching emphasizes player development through the reinforcement of basic skills during exercises known as "drills." Drills promote repetition and refinement of volleyball movements, particularly in footwork patterns, body positioning relative to others, and ball contact. A coach
will construct drills that simulate match situations thereby encouraging speed of movement, anticipation, timing, communication, and team-work. At the various stages of a player's career, a coach will tailor drills to meet the strategic requirements of the team. The American Volleyball Coaches Association
is the largest organization in the world dedicated exclusively to volleyball coaching.
There are 5 positions filled on every volleyball team at the elite level. Setter, Outside Hitter/Left Side Hitter, Middle Hitter, Opposite Hitter/Right Side Hitter and Libero/Defensive Specialist. Each of these positions plays a specific, key role in winning a volleyball match.
- Setters have the task for orchestrating the offense of the team. They aim for 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 swift and skillful appraisal and tactical accuracy, and must be quick at moving around the court.
- 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' as they have the ability to substitute for any other player on the court during each play. They do not necessarily need to be tall, as 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 color jersey than their teammates.
- Middle blockers or Middle hitters 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.
- Outside hitters or Left side hitters attack from near the left antenna. 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.
- Opposite hitters or Right side hitters carry the offensive workload for a volleyball team. Their primary responsibilities are to attack the ball from the right side and to put up a well formed block against the opponents Outside Hitters. This player hits the most balls on the team. He/she is set from the front row and the back row. Sets to the opposite usually go to the right side.
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.
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 form of offense.
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 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 to 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 front court 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.
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. Thus, all six players act as hitters at one time or another, while two can act as setters. So the 6-2 formation is actually 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 Cuban National Women's Team employs this kind of formation. It is also used in Women's NCAA play, partially due to the variant rules used which allow 12 substitutions per set (as opposed to the 6 allowed in the standard rules).
The 5-1 formation has only one player who assumes setting responsibilities regardless of his or her 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 technical skilled hitter of the team. Back-row attacks generally come from the back-right position (position 1), but are increasingly performed from back-center in high-level play.
The big advantage of this system is that the setter always has 3 hitters to vary sets with. If the setter does this well, the opponent's middle blocker may not have enough time to block with the outside hitter, increasing the chance for the attacking team to make a point.
There is another advantage: when the setter is a front-row player, he or she is allowed to jump and "dump" the ball onto the opponent's side. This too can confuse the opponent's blocking players: the setter can jump and dump or can set to one of the hitters. A good setter knows this and thus won't only jump to dump or to set for a quick hit, but as well to confuse the opponent.
The 5-1 offense is actually 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.
Variations and related games
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:
- Newcomb ball (or sometimes spelled "Nuke 'Em") - where the ball is caught and thrown instead of hit, and which rivalled volleyball in popularity until the 1920s
- Prisoner Ball - also played with volleyball court and a volleyball. People can be called out, back in.
- Footvolley - a sport from Brazil in which the hands and arms are not used but most else is like beach volleyball.
- One Touch Volleyball - a newly created, but very popular version of volleyball played without a net and where the ball is allowed to touch the ground once.
