Rules in Basketball What does defend three seconds mean?

This is an NBA rule, which means that if a defender stays in his or her 3-second zone for more than 3 seconds other than close defense, he or she will be awarded a 3-second offense. Take Yao Ming's defense of Ao Fat as an example. If Ao Fat stands outside the 3-second zone and gets stuck in Yao Ming's ball, Yao Ming is squeezed into the 3-second zone, and Yao Ming can stay in the 3-second zone for more than 3 seconds during this defensive process.

If Ao Fat is outside the 3-point line, and Yao Ming does not defend others, but just stands in the 3-second zone by himself, then if he stays for more than 3 seconds, he will be blown for defending for 3 seconds. Three-second violations are divided into three seconds for defense and three seconds for offense Defensive three seconds: It means that if a defender stands in the three-second zone and has no offensive players about 1 meter away, and he stays in the three-second zone for more than three seconds, he is considered to be defending for three seconds, and if he violates the rules twice for three seconds, he will be punished with one penalty and one execution.

Offensive three seconds: Refers to the offensive player without the ball or.

In the NBA, the "three-second defense" rule means that when a defender is standing in the three-second zone and defending, if the referee determines that he "did not defend any specific offensive player", then the defender cannot stay in the three-second zone for more than three seconds, otherwise it will be considered a "three-second offense", and the offensive team will get a free throw and continue to retain the offensive rights. According to the rules, the referee makes this decision based on the distance between the defender and the attacking player next to him, within the length of one arm's arm; That is, if the defender is more than an arm's length away from the nearest attacker, the referee will assume that he is not defending the attacker.

A defender who stands in a three-second zone and is about 1 meter away from the start without an attacking player, and who stays in the three-second zone for more than three seconds, is considered to have defended for three seconds.

A defender who stands at arm's length from the defender in the three-second zone (even if it is one foot) and stays in the three-second zone for three seconds is rewarded

When attacking, standing in a trapezoidal circle of less than 3 minutes, and not understanding 3 seconds, will cause the defense to be 3 seconds.

Defending for three seconds: The defender does not find a defender within three seconds of the three-point line.

The opponent cannot stay in the 3-second zone for 3 seconds.

The defender continues to defend for more than one second in the three-second zone.

It is to control the ball for three seconds in a three-second zone.

If the offensive player does not enter the three-second zone, the defender enters the three-second zone early (whether or not he assists another offensive player) and reaches three seconds = three seconds defending.

Three-second violations are divided into three seconds for defense and three seconds for offense.

Defending for three seconds: If a defender stands in the three-second zone and has no offensive players at a distance of about 1 meter from the start, and he stays in the three-second zone for more than three seconds, he will be deemed to have defended for three seconds, and if he violates the rules twice, he will be punished with one penalty and one execution.

Offensive 3 seconds: If an attacking player stays in the 3-second zone for more than 3 seconds without the ball or with offensive action or intent, it will be regarded as attacking for 3 seconds and will be punished for exchanging the ball!

Attacking for 3 seconds means that an attacking player who stays in the 3-second zone for more than 3 seconds is considered a violation.

Defending for 3 seconds, which means that if a defender stays in the 3-second zone (1 step away from the defender) for more than 3 seconds, it is considered a violation, if you are within 1 step of the offensive player, then no one cares about you as long as you like.

The reason why the 3-second defense rule is set up is to prevent the defenders from being crowded for 3 seconds, resulting in a decrease in the visibility of basketball.

Not defending for 3 seconds, actually attacking for 3 seconds, which means that the attacking team must make a shot within 3 seconds after entering the 3-second zone with the ball, and if there is no shot, it is an example that the defender has the ball. Defending for 3 seconds means that you can prevent the attacker from shooting for 3 seconds, so that you can get the ball. Hope to adopt.

Defend for three seconds.

1. The timing begins when the attacking team controls the ball in the front court.

2. Any defensive player who is in a 16-foot penalty area or an area that extends 4 feet beyond the baseline must be in active defense of an opposing player for three seconds. Active defense means being no more than an arm's length away from an attacking player and being in a defensive position.

3. Any defensive player can defend any offensive player. Defenders can double up on any player.

4. Defend for three seconds and interrupt the timer in the following situations:

1) A player is in the middle of a shooting action;

2) the possessor loses control of the ball;

3) The defender is actively defending an opposing player;

4) The defender is completely out of the 16-foot free throw area;

5) The defender will be legal immediately.

5. If a defender is defending a player with the ball, he may be in the 16-foot penalty area. Defenders don't need to be more than an arm's length away from the opponent to be aggressively defensive. If another defender is aggressively defending the player with the ball, the original defender must either aggressively defend an opponent or leave the 16-foot penalty area.

Once the offensive player passes the ball, the defender must also actively defend an opponent or leave the 16-foot penalty area.

Sanction: One technical foul. The attacking team continues to have possession of the ball and takes a throw-in at the sideline of the extension of the free throw line closest to where the game was interrupted.

The 24-second timer should be kept at the time of interruption in the match or reset to 14 seconds, whichever is greater. If the violation is blown during a single shot, the violation shall be cancelled and the game shall continue as if the shot was made.

Attack for three seconds. 1. When a team is in control of the ball, the players of that team shall not stay in the opponent's restricted area for more than 3 seconds.

2. All lines in the restricted area are part of the restricted area, and any line touched by the team members is considered to be in the restricted area.

3. The 3-second limit applies in all throw-ins. It is calculated from the moment the throw-in player can handle the ball (the ball enters play) outside the bounds.

4. The 3-second limit does not apply to:

1) When the shot ball is in the air;

2) When grabbing rebounds;

3) When the ball is dead.

5. When a player stays in the restricted area for nearly 3 seconds, he may acquiesce to his dribble and shoot.

Violation of this rule is a violation.

Note: There is no violation of this rule if a team does not possess the ball.
