First, the javelin. Before the javelin was changed, the world record was104m, which means that if the direction deviates, it will plunge into the stands. Later, the center of gravity of javelin moved forward, which directly led to the drop of throwing distance, but the world record was more than 98 meters after javelin change.
Those who can throw 80 or 90 meters are all international athletes, and they can't lose control. Both the discus and the hammer have a big cage. If you shoot at a specified angle, it is impossible to hit the stands.
Moreover, the track and field arrangement rules require that when throwing events begin, there should be no competition on the runway as far as possible. As for the referee, you have to pay attention to yourself. The shot put, put all your eggs in one basket, can't get into the stands.
As long as the surrounding judges pay attention. In history, referees have been stabbed by javelin, and athletes have been stabbed in other events. Athletes can only blame the mistakes of the organizing Committee for failing to arrange the venue and arrangement order.
Competition method
Olympic track and field events are usually divided into two groups, and those who pass the standard will go straight to the finals. If the number of athletes who meet the passing standards is less than 12, the insufficient number will be replenished according to the passing results.
The order of the first three rounds from the final of the project is decided by drawing lots. After the first three rounds of the final, the top eight athletes will be selected for the final three rounds according to the results; The fourth and fifth rounds are sorted in reverse order according to the results of the first three rounds, and the sixth round is sorted in reverse order according to the results of the first five rounds, with the best results jumping (throwing) at the end.
Effective achievement
In throwing events, except for foul, it is only effective when the throwing equipment of the athlete completely falls within the landing area (excluding the sideline of the landing area), and the gun head should land before the gun tail. When measuring the results, it is calculated from the nearest landing point to the throwing area. Among them, javelin must be effective if the tip touches the ground first.
