Basketball, governed primarily by the rules set forth by organizations like the NBA (National Basketball Association) and FIBA (Fédération Internationale de Basketball), consists of numerous rules. Here is an overview of the fundamental rules in basketball:
Game Structure
- Team Composition: Each team has five active players on the court and may have additional players on the bench.
- Game Duration:
- NBA: Four quarters of 12 minutes each.
- FIBA: Four quarters of 10 minutes each.
- Overtime: If the score is tied at the end of regulation, additional overtime periods are played (5 minutes in both NBA and FIBA).
Scoring
- Field Goals:
- A basket made from within the three-point line is worth 2 points.
- A basket made from beyond the three-point line is worth 3 points.
- Free Throws: Worth 1 point each, awarded after certain fouls.
Dribbling and Ball Handling
- Dribbling: Players must dribble the ball while moving. If a player stops dribbling and then starts again, it is a violation (double dribble).
- Traveling: Taking too many steps without dribbling is not allowed (usually more than two steps).
Fouls
- Personal Fouls: Physical contact that impedes an opponent’s movement.
- Five fouls in FIBA or six in the NBA results in a player fouling out.
- Shooting Fouls: Fouls committed while a player is attempting a shot; typically results in free throws.
- Technical Fouls: Non-contact violations (e.g., unsportsmanlike conduct). Results in free throws awarded to the opposing team.
Violations
- Out of Bounds: The ball is out of play if it touches the floor or any object outside the boundary lines.
- Backcourt Violation: After crossing midcourt, the offensive team cannot return the ball to the backcourt.
- Shot Clock: Teams must attempt a shot within a specified time (24 seconds in the NBA, 14 seconds on offensive rebounds).
- Three-Second Violation: An offensive player cannot remain in the key (paint area) for more than three seconds.
- Five-Second Violations:
- Closely guarded: Must either pass, shoot, or dribble within five seconds.
- Inbound: Must pass the ball within five seconds of receiving it from out of bounds.
Timeouts
- Teams can call timeouts during stoppages in play, which can be strategic to rest players or discuss tactics.
Free Throws
- Awarded after certain fouls; the player shoots from the free-throw line with no defenders.
Inbounding the Ball
- After a violation or made basket, the team that did not score gets possession to inbound the ball from out of bounds.
Substitutions
- Teams can substitute players during stoppages in play, following specific rules set by the league.
Other Key Rules
- Jump Ball: Used to start the game; two players jump for possession of the ball.
- Possession Arrow: Used in FIBA to indicate which team gets the next possession after a jump ball situation.
League-Specific Differences
- Rules may vary slightly between the NBA and FIBA, particularly regarding fouls, game duration, and the shot clock.
