Basketball's early adherents were dispatched to YMCAs throughout the United States, and it quickly spread through the USA and Canada. By 1895, it was well established at several women's high schools. While the YMCA was responsible for initially developing and spreading the game, within a decade it discouraged the new sport, as rough play and rowdy crowds began to detract from the YMCA's primary mission. However, other amateur sports clubs, colleges, and professional clubs quickly filled the void. In the years before

Dr. James Naismith was instrumental in establishing college basketball. His colleague C.O. Beamis fielded the first college basketball team just a year after the Springfield YMCA game at the suburban Pittsburgh Geneva College.^[14] Naismith himself later coached at the University of Kansas for six years, before handing the reins to renowned coach Forrest "Phog" Allen. Naismith's disciple Amos Alonzo Stagg brought basketball to the University of Chicago, while Adolph Rupp, a student of Naismith's at Kansas, enjoyed great success as coach at the University of Kentucky. On February 9, 1895, the first intercollegiate 5-on-5 game was played at Hamline University between Hamline and the School of Agriculture, which was affiliated with the University of Minnesota.^[15][16][17] The School of Agriculture won in a 9–3 game.

In 1901, colleges, including the University of Chicago, Columbia University, Cornell University, Dartmouth College, the University of Minnesota, the U.S. Naval Academy, the University of Colorado and Yale University began sponsoring men's games. In 1905, frequent injuries on the football field prompted President Theodore Roosevelt to suggest that colleges form a governing body, resulting in the creation of the Intercollegiate Athletic Association of the United States (IAAUS). In 1910, that body would change its name to the National Collegiate Athletic Association (NCAA). The first Canadian interuniversity basketball game was played at the YMCA in Kingston, Ontario on February 6, 1904, when McGill University visited Queen's University. McGill won 9–7 in overtime; the score was 7–7 at the end of regulation play, and a ten-minute overtime period settled the outcome. A good turnout of spectators watched the game.^[18]

Before widespread school district consolidation, most American high schools were far smaller than their present-day counterparts. During the first decades of the 20th century, basketball quickly became the ideal interscholastic sport due to its modest equipment and personnel requirements. In the days before widespread television coverage of professional and college sports, the popularity of high school basketball was unrivaled in many parts of America. Perhaps the most legendary of high school teams was Indiana's Franklin Wonder Five, which took the nation by storm during the 1920s, dominating Indiana basketball and earning national recognition.

Today virtually every high school in the United States fields a basketball team in

There is currently no tournament to determine a national high school champion. The most serious effort was the National Interscholastic Basketball Tournament at the University of Chicago from 1917 to 1930. The event was organized by Amos Alonzo Stagg and sent invitations to state champion teams. The tournament started out as a mostly Midwest affair but grew. In 1929 it had 29 state champions. Faced with opposition from the National Federation of State High School Associations and North Central Association of Colleges and Schools that bore a threat of the schools losing their accreditation the last tournament was in 1930. The organizations said they were concerned that the tournament was being used to recruit professional players from the prep ranks.^[20] The tournament did not invite minority schools or private/parochial schools.

The National Catholic Interscholastic Basketball Tournament ran from 1924 to 1941 at

FIBA (International Basketball Federation) was formed in 1932 by eight founding nations: Argentina, Czechoslovakia, Greece, Italy, Latvia, Portugal, Romania and Switzerland. At this time, the organization only oversaw amateur players. Its acronym, derived from the French Fédération Internationale de Basket-ball Amateur, was thus "FIBA". Men's basketball was first included at the Berlin 1936 Summer Olympics, although a demonstration tournament was held in 1904. The United States defeated Canada in the first final, played outdoors. This competition has usually been dominated by the United States, whose team has won all but three titles. The first of these came in a controversial final game in Munich in 1972 against the Soviet Union, in which the ending of the game was replayed three times until the Soviet Union finally came out on top.^[25] In 1950 the first FIBA World Championship for men, now known as the FIBA Basketball World Cup, was held in Argentina. Three years later, the first FIBA World Championship for Women, now known as the FIBA Women's Basketball World Cup, was held in Chile. Women's basketball was added to the Olympics in 1976, which were held in Montreal, Quebec, Canada with teams such as the Soviet Union, Brazil and Australia rivaling the American squads.

Worldwide, basketball tournaments are held for boys and girls of all age levels. The global popularity of the sport is reflected in the nationalities represented in the NBA. Players from all six inhabited continents currently play in the NBA. Top international players began coming into the NBA in the mid-1990s, including Croatians Dražen Petrović and Toni Kukoč, Serbian Vlade Divac, Lithuanians Arvydas Sabonis and Šarūnas Marčiulionis, Dutchman Rik Smits and German Detlef Schrempf.

Measurements and time limits discussed in this section often vary among tournaments and organizations; international and NBA rules are used in this section.

The object of the game is to outscore one's opponents by throwing the ball through the opponents' basket from above while preventing the opponents from doing so on their own. An attempt to score in this way is called a shot. A successful shot is worth two points, or three points if it is taken from beyond the three-point arc 6.75 metres (22 ft 2 in) from the basket in international games and 23 feet 9 inches (7.24 m) in NBA games. A one-point shot can be earned when shooting from the foul line after a foul is made.

Playing regulations

Games are played in four quarters of 10 (FIBA)^[33] or 12 minutes (NBA).^[34] College men's games use two 20-minute halves,^[35] college women's games use 10-minute quarters,^[36] and United States high school varsity games use 8 minute quarters.^[37] 15 minutes are allowed for a half-time break under FIBA, NBA, and NCAA rules^[35][38][39] and 10 minutes in United States high schools.^[37] Overtime periods are five minutes in length^[35][40][41] except for high school, which is four minutes in length.^[37] Teams exchange baskets for the second half. The time allowed is actual playing time; the clock is stopped while the play is not active. Therefore, games generally take much longer to complete than the allotted game time, typically about two hours.

Five players from each team may be on the court at one time.^{[42][43][44][45]} Substitutions are unlimited but can only be done when play is stopped. Teams also have a coach, who oversees the development and strategies of the team, and other team personnel such as assistant coaches, managers, statisticians, doctors and trainers.

For both men's and women's teams, a standard uniform consists of a pair of shorts and a jersey with a clearly visible number, unique within the team, printed on both the front and back. Players wear high-top sneakers that provide extra ankle support. Typically, team names, players' names and, outside of North America, sponsors are printed on the uniforms.

A limited number of time-outs, clock stoppages requested by a coach (or sometimes mandated in the NBA) for a short meeting with the players, are allowed. They generally last no longer than one minute (100 seconds in the NBA) unless, for televised games, a commercial break is needed.

The game is controlled by the

The only essential equipment in a basketball game is the ball and the court: a flat, rectangular surface with baskets at opposite ends. Competitive levels require the use of more equipment such as clocks, score sheets, scoreboard(s), alternating possession arrows, and whistle-operated stop-clock systems.

The ball may be advanced toward the basket by being shot, passed between players, thrown, tapped, rolled or dribbled (bouncing the ball while running).

The ball must stay within the court; the last team to touch the ball before it travels out of bounds forfeits possession. The ball is out of bounds if it touches a boundary line, or touches any player or object that is out of bounds.

There are limits placed on the steps a player may take without dribbling, which commonly results in an infraction known as traveling. Nor may a player stop his dribble and then resume dribbling. A dribble that touches both hands is considered stopping the dribble, giving this infraction the name double dribble. Within a dribble, the player cannot carry the ball by placing his hand on the bottom of the ball; doing so is known as carrying the ball. A team, once having established ball control in the front half of their court, may not return the ball to the backcourt and be the first to touch it. A violation of these rules results in loss of possession.

The ball may not be kicked, nor be struck with the fist. For the offense, a violation of these rules results in loss of possession; for the defense, most leagues reset the shot clock and the offensive team is given possession of the ball out of bounds.

There are limits imposed on the time taken before progressing the ball past halfway (8 seconds in FIBA and the NBA; 10 seconds in NCAA and high school for both sexes), before attempting a shot (24 seconds in FIBA, the NBA, and U Sports (Canadian universities) play for both sexes, and 30 seconds in NCAA play for both sexes), holding the ball while closely guarded (5 seconds), and remaining in the restricted area known as the free-throw lane, (or the "key") (3 seconds). These rules are designed to promote more offense.

Basket interference, or goaltending is a violation charged when a player illegally interferes with a shot. This violation is incurred when a player touches the ball on its downward trajectory to the basket, unless it is obvious that the ball has no chance of entering the basket, if a player touches the ball while it is in the rim, or in the area extended upwards from the basket, or if a player reaches through the basket to interfere with the shot. When a defensive player is charged with goaltending, the basket is awarded. If an offensive player commits the infraction, the basket is cancelled. In either case possession of the ball is turned over to the defensive team.

Fouls

An attempt to unfairly disadvantage an opponent through certain types of physical contact is illegal and is called a personal foul. These are most commonly committed by defensive players; however, they can be committed by offensive players as well. Players who are fouled either receive the ball to pass inbounds again, or receive one or more free throws if they are fouled in the act of shooting, depending on whether the shot was successful. One point is awarded for making a free throw, which is attempted from a line 15 feet (4.6 m) from the basket.

The referee is responsible for judging whether contact is illegal, sometimes resulting in controversy. The calling of fouls can vary between games, leagues and referees.

There is a second category of fouls called technical fouls, which may be charged for various rules violations including failure to properly record a player in the scorebook, or for unsportsmanlike conduct. These infractions result in one or two free throws, which may be taken by any of the five players on the court at the time. Repeated incidents can result in disqualification. A blatant foul involving physical contact that is either excessive or unnecessary is called an intentional foul (flagrant foul in the NBA). In FIBA, a foul resulting in ejection is called a disqualifying foul, while in leagues other than the NBA, such a foul is referred to as flagrant.

If a team exceeds a certain limit of team fouls in a given period (quarter or half) – four for NBA, NCAA women's, and international games – the opposing team is awarded one or two free throws on all subsequent non-shooting fouls for that period, the number depending on the league. In the US college men's game and high school games for both sexes, if a team reaches 7 fouls in a half, the opposing team is awarded one free throw, along with a second shot if the first is made. This is called shooting "one-and-one". If a team exceeds 10 fouls in the half, the opposing team is awarded two free throws on all subsequent fouls for the half.

When a team shoots foul shots, the opponents may not interfere with the shooter, nor may they try to regain possession until the last or potentially last free throw is in the air.

After a team has committed a specified number of fouls, the other team is said to be "in the bonus". On scoreboards, this is usually signified with an indicator light reading "Bonus" or "Penalty" with an illuminated directional arrow or dot indicating that team is to receive free throws when fouled by the opposing team. (Some scoreboards also indicate the number of fouls committed.)

If a team misses the first shot of a two-shot situation, the opposing team must wait for the completion of the second shot before attempting to reclaim possession of the ball and continuing play.

If a player is fouled while attempting a shot and the shot is unsuccessful, the player is awarded a number of free throws equal to the value of the attempted shot. A player fouled while attempting a regular two-point shot thus receives two shots, and a player fouled while attempting a three-point shot receives three shots.

If a player is fouled while attempting a shot and the shot is successful, typically the player will be awarded one additional free throw for one point. In combination with a regular shot, this is called a "three-point play" or "four-point play" (or more colloquially, an "and one") because of the basket made at the time of the foul (2 or 3 points) and the additional free throw (1 point).

Common techniques and practices

Positions

Although the rules do not specify any positions whatsoever, they have evolved as part of basketball. During the early years of basketball's evolution, two guards, two forwards, and one center were used. In more recent times specific positions evolved, but the current trend, advocated by many top coaches including Mike Krzyzewski is towards positionless basketball, where big guys are free to shoot from outside and dribble if their skill allows it.^[49] Popular descriptions of positions include:

Point guard (often called the "1") : usually the fastest player on the team, organizes the team's offense by controlling the ball and making sure that it gets to the right player at the right time.

Shooting guard (the "2") : creates a high volume of shots on offense, mainly long-ranged; and guards the opponent's best perimeter player on defense.

Small forward (the "3") : often primarily responsible for scoring points via cuts to the basket and dribble penetration; on defense seeks rebounds and steals, but sometimes plays more actively.

Center (the "5"): uses height and size to score (on offense), to protect the basket closely (on defense), or to rebound.

The above descriptions are flexible. For most teams today, the shooting guard and small forward have very similar responsibilities and are often called the wings, as do the power forward and center, who are often called post players. While most teams describe two players as guards, two as forwards, and one as a center, on some occasions teams choose to call them by different designations.

Strategy

There are two main defensive strategies: zone defense and man-to-man defense. In a zone defense, each player is assigned to guard a specific area of the court. Zone defenses often allow the defense to double team the ball, a manoeuver known as a trap. In a man-to-man defense, each defensive player guards a specific opponent.

Offensive plays are more varied, normally involving planned passes and movement by players without the ball. A quick movement by an offensive player without the ball to gain an advantageous position is known as a cut. A legal attempt by an offensive player to stop an opponent from guarding a teammate, by standing in the defender's way such that the teammate cuts next to him, is a

Shooting is the act of attempting to score points by throwing the ball through the basket, methods varying with players and situations.

Typically, a player faces the basket with both feet facing the basket. A player will rest the ball on the fingertips of the dominant hand (the shooting arm) slightly above the head, with the other hand supporting the side of the ball. The ball is usually shot by jumping (though not always) and extending the shooting arm. The shooting arm, fully extended with the wrist fully bent, is held stationary for a moment following the release of the ball, known as a follow-through. Players often try to put a steady backspin on the ball to absorb its impact with the rim. The ideal trajectory of the shot is somewhat controversial, but generally a proper arc is recommended. Players may shoot directly into the basket or may use the backboard to redirect the ball into the basket.

The two most common shots that use the above described setup are the

Another shot that is becoming common^{[citation needed]} is the "circus shot". The circus shot is a low-percentage shot that is flipped, heaved, scooped, or flung toward the hoop while the shooter is off-balance, airborne, falling down, and/or facing away from the basket. A back-shot is a shot taken when the player is facing away from the basket, and may be shot with the dominant hand, or both; but there is a very low chance that the shot will be successful.

A shot that misses both the rim and the backboard completely is referred to as an

. The hang time is the length of time a player stays in the air after jumping, either to make a slam dunk, lay-up or jump shot.

Rebounding

Main article: Rebound (basketball)

The objective of rebounding is to successfully gain possession of the basketball after a missed field goal or free throw, as it rebounds from the hoop or backboard. This plays a major role in the game, as most possessions end when a team misses a shot. There are two categories of rebounds: offensive rebounds, in which the ball is recovered by the offensive side and does not change possession, and defensive rebounds, in which the defending team gains possession of the loose ball. The majority of rebounds are defensive, as the team on defense tends to be in better position to recover missed shots.

Passing

See also: Assist (basketball)

A pass is a method of moving the ball between players. Most passes are accompanied by a step forward to increase power and are followed through with the hands to ensure accuracy.

A staple pass is the chest pass. The ball is passed directly from the passer's chest to the receiver's chest. A proper chest pass involves an outward snap of the thumbs to add velocity and leaves the defence little time to react.

Another type of pass is the bounce pass. Here, the passer bounces the ball crisply about two-thirds of the way from his own chest to the receiver. The ball strikes the court and bounces up toward the receiver. The bounce pass takes longer to complete than the chest pass, but it is also harder for the opposing team to intercept (kicking the ball deliberately is a violation). Thus, players often use the bounce pass in crowded moments, or to pass around a defender.

The overhead pass is used to pass the ball over a defender. The ball is released while over the passer's head.

The outlet pass occurs after a team gets a defensive rebound. The next pass after the rebound is the outlet pass.

The crucial aspect of any good pass is it being difficult to intercept. Good passers can pass the ball with great accuracy and they know exactly where each of their other teammates prefers to receive the ball. A special way of doing this is passing the ball without looking at the receiving teammate. This is called a no-look pass.

Another advanced style of passing is the behind-the-back pass, which, as the description implies, involves throwing the ball behind the passer's back to a teammate. Although some players can perform such a pass effectively, many coaches discourage no-look or behind-the-back passes, believing them to be difficult to control and more likely to result in turnovers or violations.

Dribbling

Main article:

Dribble

Dribbling is the act of bouncing the ball continuously with one hand, and is a requirement for a player to take steps with the ball. To dribble, a player pushes the ball down towards the ground with the fingertips rather than patting it; this ensures greater control.

When dribbling past an opponent, the dribbler should dribble with the hand farthest from the opponent, making it more difficult for the defensive player to get to the ball. It is therefore important for a player to be able to dribble competently with both hands.

Good dribblers (or "ball handlers") tend to bounce the ball low to the ground, reducing the distance of travel of the ball from the floor to the hand, making it more difficult for the defender to "steal" the ball. Good ball handlers frequently dribble behind their backs, between their legs, and switch directions suddenly, making a less predictable dribbling pattern that is more difficult to defend against. This is called a crossover, which is the most effective way to move past defenders while dribbling.

A skilled player can dribble without watching the ball, using the dribbling motion or peripheral vision to keep track of the ball's location. By not having to focus on the ball, a player can look for teammates or scoring opportunities, as well as avoid the danger of having someone steal the ball away from him/her.

Blocking

Main article: Block (basketball)

A block is performed when, after a shot is attempted, a defender succeeds in altering the shot by touching the ball. In almost all variants of play, it is illegal to touch the ball after it is in the downward path of its arc; this is known as

goaltending

. It is also illegal under NBA and Men's NCAA basketball to block a shot after it has touched the backboard, or when any part of the ball is directly above the rim. Under international rules it is illegal to block a shot that is in the downward path of its arc or one that has touched the backboard until the ball has hit the rim. After the ball hits the rim, it is again legal to touch it even though it is no longer considered as a block performed.

To block a shot, a player has to be able to reach a point higher than where the shot is released. Thus, height can be an advantage in blocking. Players who are taller and playing the power forward or center positions generally record more blocks than players who are shorter and playing the guard positions. However, with good timing and a sufficiently high vertical leap, even shorter players can be effective shot blockers.

Height

At the professional level, most male players are above 6 feet 3 inches (1.91 m) and most women above 5 feet 7 inches (1.70 m). Guards, for whom physical coordination and ball-handling skills are crucial, tend to be the smallest players. Almost all forwards in the top men's pro leagues are 6 feet 6 inches (1.98 m) or taller. Most centers are over 6 feet 10 inches (2.08 m) tall. According to a survey given to all NBA teams,^[when?] the average height of all NBA players is just under 6 feet 7 inches (2.01 m), with the average weight being close to 222 pounds (101 kg). The tallest players ever in the NBA were Manute Bol and Gheorghe Mureșan, who were both 7 feet 7 inches (2.31 m) tall. The tallest current NBA player is Sim Bhullar, who stands at 7 feet 5 inches (2.26 m). At 7 feet 2 inches (2.18 m), Margo Dydek was the tallest player in the history of the WNBA.

The shortest player ever to play in the NBA is Muggsy Bogues at 5 feet 3 inches (1.60 m).^[50] Other short players have thrived at the pro level. Anthony "Spud" Webb was just 5 feet 7 inches (1.70 m) tall, but had a 42-inch (1.1 m) vertical leap, giving him significant height when jumping. While shorter players are often at a disadvantage in certain aspects of the game, their ability to navigate quickly through crowded areas of the court and steal the ball by reaching low are strengths.

Hall of Fame player Larry Bird, who is white, stated in 2004 that the league needed more white players since the league's fans are mostly white. "And if you just had a couple of white guys in there, you might get them [the fans, not the guys] a little excited. But it is a black man's game, and it will be forever. I mean, the greatest athletes in the world are African-American," said Bird.^[53][54]

Variations and similar games

Main article: Variations of basketball

Dharamsala

, India.

Variations of basketball are activities based on the game of basketball, using common basketball skills and equipment (primarily the ball and basket). Some variations are only superficial rules changes, while others are distinct games with varying degrees of basketball influences. Other variations include children's games, contests or activities meant to help players reinforce skills.

There are principal basketball sports with variations on basketball including

Slamball, Streetball and Unicycle basketball. An earlier version of basketball, played primarily by women and girls, was Six-on-six basketball. Horseball is a game played on horseback where a ball is handled and points are scored by shooting it through a high net (approximately 1.5m×1.5m). The sport is like a combination of polo, rugby, and basketball. There is even a form played on donkeys known as Donkey basketball

, but that version has come under attack from animal rights groups.

Half-court

Perhaps the single most common variation of basketball is the half-court game, played in informal settings without referees or strict rules. Only one basket is used, and the ball must be "taken back" or "cleared" – passed or dribbled outside the three-point line each time possession of the ball changes from one team to the other. Half-court games require less

cardiovascular

stamina, since players need not run back and forth a full court. Half-court raises the number of players that can use a court or, conversely, can be played if there is an insufficient number to form full 5-on-5 teams.

Half-court basketball is usually played 1-on-1, 2-on-2 or 3-on-3. The latter variation is gradually gaining official recognition as

BIG3 basketball league, a professional 3x3 half court basketball league that features former NBA players, began. The BIG3 features several rule variants including a four-point field goal.^[57]

There are also other basketball sports, such as:

• 21 (also known as American, cutthroat and roughhouse)^[58]
• 42
• Around the world
• Bounce
• Firing Squad
• Fives
• H-O-R-S-E
• Hotshot
• Knockout
• One-shot conquer
• Steal The Bacon
• Tip-it
• Tips
• "The One"
• Basketball War.
• One-on-One, a variation in which two players will use only a small section of the court (often no more than a half of a court) and compete to play the ball into a single hoop. Such games tend to emphasize individual dribbling and ball stealing skills over shooting and team play.

Wheelchair basketball

Wheelchair basketball, created by disabled World War II veterans,^[59] is played on specially designed wheelchairs for the physically impaired. The world governing body of wheelchair basketball is the International Wheelchair Basketball Federation^[60] (IWBF), and is a full medal sport in the Summer Paralympic Games.

Water basketball

Water basketball, played in a swimming pool, merges basketball and water polo rules.

Beach basketball

A modified version of basketball, played on beaches, was invented by Philip Bryant.^[61] Beach basketball is played in a circular court with no backboard on the goal, no out-of-bounds rule with the ball movement to be done via passes or 2½ steps, as dribbling is next to impossible on a soft surface.^[62]

Beach basketball has grown to a very popular, widespread competitive sport. 15 Annual World Championships have been organized.

Dunk Hoops

Dunk Hoops (a.k.a. Dunk Ball) is a variation of the game of basketball, played on basketball hoops with lowered (under basketball regulation 10 feet) rims. It originated when the popularity of the slam dunk grew and was developed to create better chances for dunks with lowered rims and using altered

goaltending

rules.

Slamball

Slamball is full-contact basketball, with

trampolines. Points are scored by playing the ball through the net, as in basketball, though the point-scoring rules are modified. The main differences from the parent sport is the court; below the padded basketball rim and backboard are four trampolines set into the floor, which serve to propel players to great heights for slam dunks

. The rules also permit some physical contact between the members of the four-player teams.

Streetball

Streetball is a less formal variant of basketball, played on playgrounds and in gymnasiums across the world. Often only one half of the court is used, but otherwise the rules of the game are very similar to those of basketball. The number of participants in a game, or a run, may range from one defender and one person on offense (known as one on one) to two full teams of five each. Streetball is a very popular game worldwide, and some cities in the United States have organized streetball programs, such as midnight basketball. Many cities also host their own weekend-long streetball tournaments.

Unicycle Basketball

Unicycle basketball is played using a regulation basketball on a regular basketball court with the same rules, for example, one must dribble the ball while riding. There are a number of rules that are particular to unicycle basketball as well, for example, a player must have at least one foot on a pedal when in-bounding the ball. Unicycle basketball is usually played using 24" or smaller unicycles, and using plastic pedals, both to preserve the court and the players' shins. In North America, popular unicycle basketball games are organized.^[63]

Spin-offs from basketball that are now separate sports include:

• Ringball, a traditional South African sport that stems from basketball, has been played since 1907. The sport is now promoted in South Africa, Namibia, Botswana, Lesotho, India, and Mauritius to establish Ringball as an international sport.
• Korfball (Dutch: Korfbal, korf meaning 'basket') started in the Netherlands and is now played worldwide as a mixed gender team ball game, similar to mixed netball and basketball
• Netball (formerly known as Women basketball but now played by both males and females), a limited-contact team sport in which two teams of seven try to score points against one another by placing a ball through a high hoop.
