(1) The order of athletes' trial jump is determined by drawing lots.
(2) Before the start of the competition, the referee should announce the take-off height and crossbar raising plan to the athletes, which will last until only the last winner or the first place is tied.
(3) Before there is only one athlete left, the height of the crossbar shall not be less than 2 cm at a time. In the all-around competition, the height of each round is 3 cm.
(4) Athletes must take off on one foot.
(5) After the competition starts, athletes are not allowed to use the take-off area for practice.
(6) If one of the following circumstances occurs, it is judged that the trial jump failed: during the trial jump, the crossbar was knocked off; Before crossing the crossbar, any part of the body touches the ground or landing area between columns and outside the vertical plane of the crossbar extension line.
(7) Athletes can start taking off at any declared altitude, or decide whether to avoid taking off at any subsequent altitude. At one altitude, 1 attempt or after two failures, athletes can still request to skip, but the number of attempts at the next altitude should be the number remaining after the previous altitude attempt, but it is not allowed to resume attempts at that altitude. No matter at any height, as long as the athlete fails three times in a row, he will be disqualified from continuing the competition. Except for the finals held because of equal results.
(8) Competition ranking should be based on the best performance of athletes. When the results are equal, those who try to jump less at the last jump height rank first; If you still can't decide the ranking, then put the athletes with fewer failures in the whole game in the first place; If it is equal again, it does not involve the first place, and the ranking is tied; When the first place is involved, the final ranking match will be held.
