In the NBA, there are several referees, how to divide the labor

1, 3 people 2, there is no division of labor, the referee follows, the deputy referee has a baseline on both sides 3, gesturing has a set of professional actions, indicating the direction of the foul hand, which side is the player of the basket who fouls, and then reports the number to the technical desk.

4,3 referees have almost equal powers, there is no division of labor.

5, the standing position was said in 2.

6, not necessarily, depending on which referee blows the foul, the foul is the left hand into a fist, straight over the head, the right hand straight palm down, five fingers together. Coupled with the specific action, it indicates what the specific foul is, just like inserting the waist to signal blocking, holding the wrist of the right hand with the left hand is to indicate the beater, and the hands are pushed out like playing Tai Chi to signal the pusher.

If it is a violation, only the left fist is extended above the head, the right hand is not moved, plus the number, and the specific foul matter, such as the hands wheeled like wheels to indicate walking, and so on.

1 referee Responsible for fouls of the personnel on the field There are also basic game problems and so on 2 linesmen are responsible for watching the ball in the front court or the ball in the back court There are also professional names **Referee, leading referee, tracking referee

There are three referees in total, and the division of labor is clear and reasonable.

A referee is placed on the baseline, one on the weak sideline, and one on the middle line, basically standing in an equilateral triangle like a triangle attack, when the ball is on the outside, the sideline referee stands on the foul-line extension as shown in the picture, and when the ball falls into the low post, he also has to stand down accordingly. Often, the division of labor is that the weak-side referee focuses on the off-ball person, the baseline looks at the low post and counts three seconds, and the mid-line referee watches the ball and follows the fast attack. The field of vision of the three referees should be said to be quite reasonable, and there is basically no blind spot compared to the double referees.

According to the division of labor, the two-person law enforcement can be divided into front-court referees and tracking referees.

The frontcourt referee is responsible for the area from the left side of the three-second zone to the right sideline, the free throw line and the right extension of the free throw line to the baseline. Track referees are responsible for other areas. Generally, the frontcourt referee is responsible for fouls in the area, cylinder space, etc.

Keep track of everything in the referee's area of responsibility, as well as assist the front court referee in the area of responsibility, etc., as well as whether the goal is valid, threes or twos, etc.

When Referee A stands in the bottom corner of one side, Referee B should stand in the corner of the other half, and after taking turns to attack, Referee A runs to the corner of the half court on his side, and Referee B runs to the bottom corner of his side.

In fact, there is no such thing as "referee" in the basketball referee, but when the incident occurs, the referee who is closest to the point of the event is the main referee, whether it is a two-person referee or a three-person referee, the running positions between the referees are complementary, and under many conditions, the referees will switch positions, for example, when the leading referee blows a foul on the defender, he will run to the front of the recording table to report the number, at this time, the original tracking referee will go down to the bottom line to occupy the position of the leading referee and become the new leader. And the referee who reported the number will become the tracking referee of the attack.

The NBA now seems to have 3 people, basically 1 person tracking, 2 people leading, and the referee's position is very flexible.

And there seems to be one dominant among the three, that is, the referee seems to have more running positions and has always been in the lead.

It seems that the rules of FIBA are now 3 people.

One referee is on the pitch, two linesmen are out of bounds, a fourth referee is in charge of substitutions, and one is a substitute linesman (only this year), if the referee is injured, the substitute is used.

3 referees and 1 repetition.

Referee: 2 wing referees.

The referee is the referee. The referee is mainly responsible for the enforcement activities in the blind spot area of the referee on both sides, including offside, handball, throw-in violations, etc., and there is a fourth assistant referee responsible for off-court substitutions, as well as injury overtime and other negotiations.

5 people. Specific points.

Bai works as follows:

Du No. 1 is the main referee, but Zhi can move around the field at will, and he will make the final decision; The No. 2 and No. 3 assistant referees are active on the two sidelines, responsible for offside and assisting the referee in the decision; No. 4 and No. 5 are the baseline referees, they have no flag or whistle, communicate with the referee by radio, and their main activities are near the goal. Platini said: "The addition of a referee on each side will give you a more accurate decision if the ball is offside or not. ”

Three referees, one referee and two linesmen (each in charge of two halves). Of course, there is a fourth ** off the field.

Is the landlord on a task? Me too, I hope the landlord will adopt me, and I'm close to one of them, thank you.

4 1 referees.

2. Linesman (with good eyes).

1. Fourth** (who specializes in controlling the emotions of the coach).

4 referees.

Two linesmen. An assistant referee.

3, one referee, two assistant referees, referee decision, assistant referee is responsible for offside, throw-in decision.

Four referees, one referee and three vice-referees, the referee is responsible for checking whether there are fouls and cards, and the deputy referee is responsible for judging the sideline ball and whether there is offside.

There are three referees in the basketball court, the chief referee, the first deputy referee, and the second deputy referee, but these three names are only distinguished before and after the start of the game and in some special circumstances, and on the court, there is no distinction between the main and secondary referees, and they are divided into leading, **, and tracking referees.

The area in charge of the lead referee and when the player cuts to the basket in the 6th zone;

Track the area for which the referee is responsible.

Zone 5 is a condominium area;

When the ball is in the area of the tracking referee, the tracking referee is responsible for observing the ball and the situation around the ball, and the leading referee observes the no-ball area and the 3-second violation; When the ball is in the area of the leading referee, the leading referee is responsible for observing the ball and the situation around the ball, tracking the referee to observe the no-ball area and the 3-second violation; When the ball is in the condominium, the two watch together.

The leading referee is responsible for the right sideline and the end line of the front court in the direction of attack; The trailing referee is responsible for the left sideline and the middle line.

The leading referee should stand outside the bottom line, keep the player with the ball in sight, and the leading referee generally stands on the left side of the sideline of the offensive free throw line to pay attention to the foul of the non-player, and pay attention to the offensive side for three seconds, but this is not absolute, the most important thing is that the two referees should cooperate tacitly.

There are three in total, two assistant referees, one resident referee Two assistant referees one stands on one sideline, and the referee is responsible for the situation on the court On the basketball court, the referee is the largest, and he can even send the deputy referee off the court
