    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. It has been a part of the official program of the Summer Olympic Games since 1964.

    The complete rules are extensive. But simply, play proceeds as follows: a player on one of the teams begins a ''rally'' by serving the ball (tossing or releasing it and then hitting it with a hand or arm), from behind the back boundary line of the court, over the net, and into the receiving team''s court. The receiving team must not let the ball be grounded within their court. The team may touch the ball up to 3 times but individual players may not touch the ball twice consecutively. Typically, the first two touches are used to set up for an attack, an attempt to direct the ball back over the net in such a way that the serving team is unable to prevent it from being grounded in their court.

    The rally continues, with each team allowed as many as three consecutive touches, until either (1): a team makes a kill, grounding the ball on the opponent''s court and winning the rally; or (2): a team commits a fault and loses the rally. 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:

    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.

    A number of consistent techniques have evolved in volleyball, including spiking and blocking (because these 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 and offensive and defensive structures.

    History Origin of volleyballWilliam G. Morgan

    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 and handball. 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 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 ft × 50 ft (7.6 m × 15.2 m) 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.

    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 evolved over time: in the Philippines by 1916, the skill and power of the set and spike had been introduced, and four years later a "three hits" rule and a rule against hitting from the back row 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 as in 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 is also a sport at the Paralympics managed by the World Organization Volleyball for Disabled.

    Nudists were early adopters of the game with regular organized play in clubs as early as the late 1920s. By the 1960s, a volleyball court had become standard in almost all nudist/naturist clubs.

    Volleyball in the Olympics Main article: Volleyball at the Summer Olympics

    The history of Olympic volleyball traces back to the 1924 Summer Olympics in Paris, 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: 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. The 1984 women''s tournament was also won by a rising force, China.

    At the 1988 Games, Karch Kiraly and Steve Timmons led the U.S. men''s team to a second straight gold medal, and the Soviets won the fourth gold in the women''s tournament. In 1992, underrated Brazil upset favourites C.I.S., Netherlands, and Italy in the men''s competition for the country''s first volleyball 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 all three games the strong Cuban female team lead by Regla Torres and Mireya Luis won the Gold medal. In 2004, Brazil won its second men''s volleyball gold medal beating Italy in the finals, while China beat Russia for its second women''s title. In the 2008 Games, the USA beat Brazil in the men''s volleyball final. Brazil was runner-up again at the 2012 Summer Olympics, this time losing to Russia after losing two match points in the third set. In both games Brazil''s women team beat the United States for the gold medal.

    Rules of the gameVolleyball courtThe court dimensions

    A volleyball court is 18 m (59 ft) long and 9 m (29.5 ft) wide, divided into 9 m × 9 m halves by a one-meter (40-inch) wide net. The top of the net is 2.43 m (8 ft 0 in) above the center of the court for men''s competition, and 2.24 m (7 ft 4 in) for women''s competition, varied for veterans and junior competitions.

    The minimum height clearance for indoor volleyball courts is 7 m (23 ft), although a clearance of 8 m (26 ft) is recommended.

    A line 3 m (9.84 ft) 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 (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".

    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 antenna (or their theoretical extensions to the ceiling) without contacting them.

    The ball Main article: Volleyball (ball)

    FIVB regulations state that the ball must be spherical, made of leather or synthetic leather, have a circumference of 65–67 cm, a weight of 260–280 g and an inside pressure of 0.30–0.325 kg/cm2. Other governing bodies have similar regulations.

    Game playWhite is on the attack while red attempts to blockBuddhist monks play volleyball in the Himalayan state of Sikkim, India.

    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 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 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. 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 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. 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. A ball is "in" if any part of it touches 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 actually 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.

    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, or playing the ball when it is above the opponent''s court.

    ScoringScorer''s table just before a game

    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. If the ball hits the line, the ball is counted as in. 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 serving team 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 is 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 NCAA matches are played best-of-five to 25 as of the 2008 season.)

    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 Championship was 2000. Rally point scoring debuted in 2001 and games were played to 30 points through 2007. For the 2008 season, games were renamed "sets" and reduced to 25 points to win.

    Libero

    In 1998 the libero player was introduced internationally. 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 he or she 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 whom 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.

    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.) 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".

    Changes in rules have been studied and announced by the FIVB in recent years, and they have released the updated rules in 2009.

    Skills

    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.

    ServeSetting up for an overhand serve.A player making a jump serve.

    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 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. 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:

    PassA 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.

    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 are acceptable in professional and beach volleyball, however there are much tighter regulations on the overhand pass in beach volleyball.

    SetJump set

    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". 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.

    AttackA Spanish player, in red outfit, about to spike towards the Portuguese field, whose players try to block the way.

    The attack, also known as the spike, 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:

    Block3 players performing a block

    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.

    Dig Main article: Volleyball digPlayer going 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. 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. It varies from passing however in that is it 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''re 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 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, but rarely if ever in beach volleyball because the uneven and infirm nature of the sand court limits the chances that the ball will make a 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 his or her 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

    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. These team 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 offense 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, below). Popular formations include the 4-2, 6-2, and 5-1 systems (see Formations, below). There are also several different attacking schemes teams can use to keep the opposing defense off balance.

    Coverage systems are the formations used by the offense 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 the formations used by the defense to protect against the ball being grounded into their court by the opposing team. The system will outline which players are responsible for which 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 defense. There are also several different blocking schemes teams can employ to disrupt the opposing teams offense.

    Some teams, when they are ready to serve, will line up their other five players in a screen to obscure the view of the receiving team. This action is only illegal if the server makes use of the screen, so the call is made at the referees discretion as to the impact the screen made on the receivers ability to pass the ball. The most common style of screening involves a W formation designed to take up as much horizontal space as possible.

    Coaching Basic

    Coaching 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.

    StrategyAn image from an international match between Italy and Russia in 2005. A Russian player on the left has just served, with three men of his team next to the net moving to their assigned block positions from the starting ones. Two others, in the back-row positions, are preparing for defense. Italy, on the right, has three men in a line, each preparing to pass if the ball reaches him. The setter is waiting for their pass while the middle hitter with no. 10 will jump for a quick hit if the pass is good enough. Alessandro Fei (no. 14) has no passing duties and is preparing for a back-row hit on the right side of the field. Note the two liberos with different color dress. Middle hitters/blockers are commonly substituted by liberos in their back-row positions.Player specialization

    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.

    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 aren''t able to effectively play back court defense. Similarly, teams might use a Serving Specialist to sub out a poor server situationally.

    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 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.

    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. 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).

    5–1

    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, known as zone 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 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: 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 when setting outside 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.
