ABSTRACT

This report will give you briefly about the basketball, the popular sport of United State of America.
TABLE OF CONTENTS
INTRODUCTION
This article is about the sport. For the ball used in the sport, see Basketball (ball). For other uses, see Basketball (disambiguation).

Basketball is a team sport in which two teams of 5 players try to score points against one another by placing a ball through a 10 foot (3.048 m) high hoop (the goal) under organized rules. Basketball is one of the most popular and widely viewed sports in the world.[1]

Points are scored by throwing (shooting) the ball through the basket from above. dunking and slamming the ball into the rim, or any other acrobatic styles to make the ball into the basket from any distance; the team with more points at the end of the game wins, but additional time(overtime) may be issued when the scores of both teams are the same. The ball can be advanced on the court by bouncing it (dribbling) or passing it between teammates. Disruptive physical contact (foul) is penalized and free throws will be issued if the player is fouled while shooting the ball and there are restrictions on how the ball can be handled (violations).

Through time, basketball has developed to involve many common techniques of shooting, passing and dribbling, as well as players' positions, and offensive and defensive structures. Typically, the tallest members of a team will play center or one of two forward positions, while shorter players or those who possess the best ball handling skills and speed, play the guard positions. While competitive basketball is carefully regulated, numerous variations of basketball have developed for casual play. In some countries, basketball is also a popular spectator sport.

While competitive basketball is primarily an indoor sport, played on a basketball court, less regulated variations played in the outdoors have become increasingly popular among both inner city and rural groups.

BODY

HISTORY


In early December 1891, Dr. James Naismith,[2] a Canadian-born physical education professor and instructor at the International Young Men's Christian Association Training School[3] (YMCA) (today, Springfield College) in Springfield, Massachusetts, USA, sought a vigorous indoor game to keep his students occupied and at proper levels of fitness during the long New England winters. After rejecting other ideas as either too rough or poorly suited to walled-in gymnasiums, he wrote the basic rules and nailed a peach basket onto a 10-foot (3.05 m) elevated track. In contrast with modern basketball nets, this peach basket retained its bottom, and balls had to be retrieved manually after each "basket" or point scored; this proved inefficient, however, so a hole was drilled into the bottom of the basket, allowing the balls to be poked out with a long dowel each time. The peach baskets were used until 1906 when they were finally replaced by metal hoops with backboards. A further change was soon made, so the ball merely passed through, paving the way for the game we know today. A soccer ball was used to shoot baskets. Whenever a person got the ball in the basket, his team would gain a point. Whichever team got the most points won the game.[4] The baskets were originally nailed to the mezzanine balcony of the playing court, but this proved impractical when spectators on the balcony began to interfere with shots. The backboard was introduced to prevent this interference; it had the additional effect of allowing rebound shots.[5] Naismith's handwritten diaries, discovered by his granddaughter in early 2006, indicate that he was nervous about the new game he had invented, which incorporated rules from a children's game called "Duck on a Rock", as many had failed before it. Naismith called the new game "Basket Ball".[6]

The first official game was played in the YMCA gymnasium on January 20, 1892 with nine players. The game ended at 1-0; the shot was made from 25 feet (7.6 m), on a court just half the size of a present-day Streetball or National Basketball Association (NBA) court. By 1897–1898 teams of five became standard.


RULES AND REGULATIONS


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 which is 6.25 metres (20 ft 6 in) from the basket in international games and 23 feet 9 inches (7.24 m) in NBA games.

PLAYING REGULATIONS


Games are played in four quarters of 10 (international) or 12 minutes (NBA). College games use two 20-minute halves, while high school games use 8 minute quarters. Fifteen minutes are allowed for a half-time break, and two minutes are allowed at the other breaks. Overtime periods are five minutes long. 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 (out of a twelve player roster) may be on the court at one time. 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 (140 seconds in the NBA) unless, for televised games, a commercial break is needed.

The game is controlled by the officials consisting of the referee (referred to as crew chief in the NBA), one or two umpires (referred to as referees in the NBA) and the table officials. For college, the NBA, and many high schools, there are a total of three referees on the court. The table officials are responsible for keeping track of each teams scoring, timekeeping, individual and team fouls, player substitutions, team possession arrow, and the shot clock.



POSITIONS AND STRUCTURES



Basketball positions in the offensive zoneAlthough the rules do not specify any positions whatsoever, they have evolved as part of basketball. During the first five decades of basketball's evolution, one guard, two forwards, and two centers or two guards, two forwards, and one center were used. Since the 1980s, more specific positions have evolved, namely:

1.point guard: 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
2.shooting guard: creates a high volume of shots on offense; guards the opponent's best perimeter player on defense
3.small forward: 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
4.power forward: plays offensively often with his back to the basket; on defense, plays under the basket (in a zone defense) or against the opposing power forward (in man-to-man defense)
5.center: uses height and size to score (on offense), to protect the basket closely (on defense), or to rebound.
The above descriptions are flexible. On some occasions, teams will choose to use a three guard offense, replacing one of the forwards or the center with a third guard. The most commonly interchanged positions are point guard and shooting guard, especially if both players have good leadership and ball handling skills.

There are two main defensive strategies: zone defense and man-to-man defense. Zone defense involves players in defensive positions guarding whichever opponent is in their zone. In man-to-man defense, each defensive player guards a specific opponent and tries to prevent him from taking action.

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 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 screen or pick. The two plays are combined in the pick and roll, in which a player sets a pick and then "rolls" away from the pick towards the basket. Screens and cuts are very important in offensive plays; these allow the quick passes and teamwork which can lead to a successful basket. Teams almost always have several offensive plays planned to ensure their movement is not predictable. On court, the point guard is usually responsible for indicating which play will occur.

Defensive and offensive structures, and positions, are more emphasized in higher levels in basketball; it is these that a coach normally requests a time-out to discuss.

CONCLUSION
Dr. James Naismith is known world-wide as the inventor of basketball. He was born in 1861 in Ramsay township, near Almonte, Ontario, Canada. The concept of basketball was born from his school days in the area where he played a simple child's game known as duck-on-a-rock outside his one-room schoolhouse. The game involved attempting to knock a "duck" off the top of a large rock by tossing another rock at it. Naismith went on to attend McGill University in Montreal, Quebec, Canada.
After serving as McGill's Athletic Director, he moved on to the YMCA Training School in Springfield, Massachusetts, USA in 1891 where the sport of basketball was born. In Springfield, Naismith was faced with the problem of finding a sport that was suitable for play inside during the Massachusetts winter for the students at the School for Christian Workers. Naismith wanted to create a game of skill for the students instead of one that relied solely on strength. He needed a game that could be played indoors in a relatively small space. The first game was played with a soccer ball and two peach baskets used as goals.

In addition to the creation of the sport, Naismith graduated as a medical doctor, primarily interested in sports physiology and what we would today call sports science and as Presbyterian minister, with a keen interest in philosophy and clean living. Naismith watched his sport, introduced in many nations by the YMCA movement as early as 1893. Basketball was introduced at the Berlin Olympics in 1936. Today basketball has grown to become one of the world's most popular sports.
