Referee is an important part of the competition, which directly affects the competition and the technical level of athletes. The purpose of referee's work is to ensure fair competition and ensure that athletes compete under equal competition conditions. Athletes can neither gain any improper benefits nor suffer losses in the competition, and create the best competition conditions for athletes. Therefore, we should be "serious, fair, accurate, modest and prudent, United and cooperative" in our work. 1. Characteristics of referee work in large-scale track and field competitions 1. Modern electronic instruments and equipment are used in referee work. In order to make track and field competitions more fair and accurate, many high-tech electronic equipment are used in referee work. Such as using automatic electronic timing device instead of manual timing; Laser rangefinder replaces ruler and steel ruler to measure height and distance; The first foul monitor can better determine the athletes responsible for the first foul; The application of computer and network equipment has realized high-speed intelligent management integrating competition organization, recording, result processing and publishing, inquiry and information publishing. Therefore, modern referee work is done by referees and technicians who master electronic instruments and equipment. 2. Referees in large-scale track and field competitions have fine division of labor, strong professionalism, large track and field, many events (there are more than 40 Olympic track and field events), many athletes and many groups. Therefore, under the leadership of the track referee, the track events are decided by the referee groups and related technicians. The work of each referee group is independent and closely coordinated to complete the competition task together. With the continuous improvement of competitive level, referees are required to make accurate judgments on scores and rankings. Advanced instruments and equipment have entered the referee work, making the division of labor more detailed. For example, in the past, 4-5 referees could complete the task in a throwing event. Now, the division of labor is composed of internal and external referees, recorders, landing referees, terminal operators, timekeepers, laser rangefinders, scoreboard operators and management referees. * * * Need 12 ~ 15 people. 3. The cooperation of referees in large-scale track and field competitions In a large-scale track and field competition, there are as few as several hundred athletes and as many as several thousand. There are more than 2,000 athletes participating in the world track and field championships, and 10,000-person marathons are often held internationally. Therefore, large-scale competitions are the characteristics of track and field competitions. In international large-scale competitions, the number of referees is generally 200, and the number of assistant referees is about 100. For example, there are 0/80 track and field referees and 60 assistant referees in the 9th National Games. 4. Instruct athletes to compete with signals. At the newspaper office, there is a large registration time display board, which can display the events, competition time, registration start time and registration end time. Before the start of track events, the referee will remind the referee, the athletes and the audience with audio signals, then the big screen in the venue will display the information of the athletes, the announcer will introduce the athletes, and then the starter will organize the athletes to start. In all field events, the athletes' trial jump and trial throw start with the athletes' numbers displayed on the display screen, rather than the referee's call. After the athlete's number is displayed, the referee immediately removes the stop sign and starts to calculate the athlete's time limit. 5. The referee work of international large-scale track and field competitions should be carried out in strict accordance with the provisions of the IAAF competition manual. 2. Referee-(related content of track and field competition rules) 1. The judges of track and field events, record check, all-around and outfield (running and walking) are appointed respectively. Track referees and outfield referees have no right to govern matters within the scope of referees' duties. 2. The referee shall ensure that the provisions of the track and field rules and technical regulations are implemented and deal with any problems that occur during the sports meeting and are not expressly stipulated in the track and field rules. Only when the referee disputes the ranking can he not judge, and the track referee and the outfield referee have the right to judge the ranking of the competition. If the track referee disagrees with the decision of the starting team, he can make a decision on any problems arising from the starting, except when using the starting foul monitor. 3. The referee should check all the relevant competition results, deal with any controversial issues, and supervise and record the score measurement when there is no (electronic) measurement referee. 4. The referee should make a ruling on the protests or objections about the game and any problems that occur at the check-in office. Have the right to warn or disqualify athletes who have misbehaved. Give the athletes a warning and show them a yellow card. If he is disqualified, he should show a red card. These two punishments should be filled in on the record card. In any sports meeting, if the referee thinks that a match or any part of a match should be played again, it is fair, he has the right to declare the match invalid and make a decision to play again on the same day or at other times. 6. After each competition, a record form should be filled out immediately, signed by the relevant referee, and then submitted to the competition secretary. (Domestic competitions are submitted to the Arranging and Filing Group) 7. The all-around referee has jurisdiction over the progress of the all-around competition. He also has jurisdiction over the progress of individual events in all-around events.
