In the long jump competition, what jumps should athletes complete after the run-up?

In the competition, athletes should jump three times in a row in different forms after the run-up. The first jump is one-legged jump, landing with the take-off leg; The second jump is a step jump, swinging your legs and landing; The third jump is a jump, and you must land on your feet and fall into the bunker.

Specific rules

1. Draw lots to decide the order of athletes' trial jumps.

2. If there are more than 8 athletes, each athlete should be allowed to try to jump 3 times. The top 8 athletes with the best effective results can try to jump three times, and the order of the trial jump is opposite to the ranking after the first three attempts. If the eighth place is equal after the third attempt, it will be handled according to the rule 146 3. When there are only 8 people or less in the competition, each person can try to jump 6 times.

Once the competition starts, athletes are not allowed to practice by means of competition.

4. When one of the following circumstances occurs, the trial jump fails:

(a) In the run-up or jump without jumping, the athlete touches the ground other than the high jumper with any part of his body;

(b) Jumping from the front or rear of jumper extension lines other than the two ends of the springboard;

(c) Touching the ground outside the landing area during landing, and the contact point outside the landing area is closer to the jumper than the nearest contact point in the area;

(d) After completing the test jump, walk backwards out of the landing zone;

(e) Take any somersault position.

Note: it is not a foul for an athlete to run out of the approach mark line at any position during the run-up process.

5. In addition to the provisions in 4(b) above, it is effective for athletes to take off behind the springboard.

6. When measuring the performance, it should be measured from the nearest point where any part of the athlete touches the ground to the jump shot or the extension line of the jump shot, and the measuring line should be perpendicular to the jump shot or its extension line.

7. Each athlete's best 1 trial jump performance, including the trial jump performance of the final ranking match due to the equal performance of 1, shall be regarded as the final result.

runway

8. The length of the run-up lane shall be at least 40 meters, and at least 45 meters if conditions permit. The minimum width of the run-up lane is1.22m, and the maximum width is1.25m. The run-up lane shall be marked with a white line with a width of 5cm.

9. The maximum left-right inclination of the approach road shall not exceed 1: 100, and the total inclination of the driving direction shall not exceed 1: 1000.

10. castanets: In order to help the run-up and take-off, athletes can run on the run-up runway. 1 ~ 2 mark (approved or provided by the organizing Committee) is placed next to it. If such a mark is not provided, athletes may use adhesive tape, but chalk or any other similar substance that cannot erase traces is prohibited.

Take the springboard in the long jump.

1 1. The springboard is a sign of takeoff, so it should be placed underground, and its upper edge should be flush with the ground of the approach road and landing area. The edge of the springboard near the landing area is called the platform. A plasticine display board should be placed near the high jumper to facilitate the referee's judgment.

If the above device cannot be installed, the following methods should be adopted to lay soft soil or sand near the front of the jumper, with a width of cm and an angle of 30 degrees with the horizontal plane.

12, the distance from the springboard to the far end of the landing area should not be less than10m.

13. The distance from the springboard to the near end of the landing area is 1 ~ 3m.

Structure: The springboard should be rectangular, made of wood or other suitable hard materials, with a length of .21~1.22m, a width of 20cm (2mm), a thickness of10cm and painted white.

15. plasticine exhibition board: made of wood or other suitable materials, with a hard texture and a length of. Zi ~ 1.22m, cm (2mm) wide. This board should be placed in the recess or shelf in front of the springboard, and the height is 7 mm higher than the springboard. The edge of the exhibition board should be inclined to the direction of the run-up lane by 30 degrees, and the inclined surface should be covered with 1 mm thick plasticine, or the corners should be cut off and filled with plasticine to make it inclined by 30 degrees. When the display board is installed in the groove, all devices must be strong enough to bear all the force of the athlete's jumping feet. The display board under the plasticine should be made of a material that allows the athlete's shoe needle to grasp firmly and not slip. The plasticine layer can be leveled with a roller or other scraper to eliminate the athlete's footprint.

Note: it is more convenient to have spare rubber clay tablets, and eliminating footprints will not delay the game.

Falling area

16. The minimum width of the landing zone is 2.75m and the maximum width is 3m. If possible, his runway should be in the center of the landing zone. When extended, the center line of the run-up lane coincides with the center line of the landing zone.

Note: When the center line of the landing area does not coincide with the center line of the approach road, one or two isolation belts should be arranged in the landing area to make the two lines coincide.

17, the landing area should be filled with wet sand, and the sand surface should be flush with the springboard.

1. The order of triple jump is one jump, one span and one jump.

2. Touch the ground with the take-off leg when jumping on one foot, touch the ground with the other leg (swinging leg) when striding, and then complete the jumping action.

When an athlete swings his leg and touches the ground in the jump, it should not be regarded as a failure in the trial jump.

Triple jump springboard

3. Springboard: The distance from the springboard to the far end of the landing area shall not be less than 2 1 meter.

4. In international competitions, it is suggested that the distance from the springboard to the near end of the landing area should not be less than 13m. In other competitions, this distance should be adapted to the competition level.

5. In order to facilitate the athletes to jump and take off, there should be a solid and uniform ground at least 65438 0.22 meters wide between the springboard and the landing area.
