Track and Field RulesNo. 173 Long Jump and Triple Jump Competition China Sports Network www. sport 120.com 1。 The order of athletes' trial jump is determined by drawing lots. 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. If one of the following circumstances occurs, it is judged as a failure in the trial jump: (1) In the run-up or non-jump jump, the athlete touches the ground outside the jump line 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. Run-up on the eighth runway. The run-up lane is at least 40 meters long, and at least 45 meters when conditions permit. The minimum width of the run-up lane is l.22, and the maximum width is L.22m. 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. L ~ 2 markers (approved or provided by the organizing Committee) are placed next to it. If you don't mention it. For this mark, athletes can use adhesive tape, but it is forbidden to use chalk or any other similar substance that cannot erase traces. The springboard of the long jump is 1 1. Springboard is a sign of take-off, which should be buried underground, and its upper edge should be flush with the ground of 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. The falling area is 16. The minimum width of the falling area 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. Rules of Track and Field Rules of Triple Jump Competition 174 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. The springboard of the triple jump. Springboard: the distance from the springboard to the far end of the landing area shall not be less than 2 1 m. 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 complete the jumping action, at least1.22m wide monitoring and homogeneous ground should be provided between the springboard and the landing area. Note: In other cases, the rules of long jump are applicable to triple jump. Long jump 1. If the following situations occur, it is judged as a failure in the trial jump: (1) In the run-up without take-off or in the take-off, the athlete touches the ground behind the jumper with any part of his body; (b) Take off from the left and right ends of the springboard, whether before or after the green extension of the take-off; (c) Contact the ground between the jumper and the landing zone; (d) Explore any somersault posture in the run-up or jump; (e) Touching the ground outside the landing zone during landing, and the contact point outside the landing zone is closer to the jumper than the nearest contact point inside the landing zone; (f) When leaving the landing area, the distance from the ground outside the landing area to the parachutist is closer than the nearest landing point left on the sand in the landing area. Note 1: It is not a failure for an athlete to run out of the runway marking line at any position during the run-up process. Note 2: According to the above method of 1(b), taking off before taking off and some feet or shoes touching the ground on both sides of the springboard will not be judged as failure. Note 3: During landing, any part of the body touches the ground outside the landing zone, and it is not judged as a failure, unless the first contact place is outside the landing zone, or the above 1(e) is violated. Note 4: When the athlete has left the landing zone in the right way and then walked backwards out of the landing zone, it is not judged as a failure. 2. In addition to the above 1(b), when an athlete takes off before the springboard, he should measure his performance from the nearest point where any part of his body or limbs touches the ground to the jumper or the extension line of the jumper, and the measurement line should be perpendicular to the jumper or its extension line. Takeaway board 4. The take-off board is a sign of take-off and should be buried underground, and its surface should be flush with the surface 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. 5. The distance from the springboard to the landing area should be at least10m. 6. The distance from the springboard to the near end of the landing area is 1-3m. 7. The springboard for Architecture should be rectangular, made of wood or other suitable hard materials, with a length of (1.22m 0.0 1 m), a width of 20cm (2mm), a thickness of10cm and painted white. 8. The plastic indicator board should be made of wood or other suitable materials, with hard texture, length 1.22m 0.0 1m, width 10cm < 2mm >, and different colors from the jumping skin. If possible, plasticine should be a third different color. The height of the groove or frame placed in front of the springboard is more than 7 mm < 1 mm >. The edge of the exhibition board should be inclined at 45 degrees to the direction of the run-up lane, and the inclined surface should be covered with plasticine with a thickness of 1mm, or the corners should be cut off and filled with plasticine to make it inclined at 45 degrees. (See the attached circle) Gypsum should also be laid at the front edge of the whole exhibition board about10 mm. When the exhibition board is put into the pit, all devices must be strong enough to bear all the strength of the athletes. The display board under the plasticine should be made of a material that allows the athlete's spikes to firmly grasp 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 a spare plasticine board to avoid delaying the game when leveling the footprint. Landing zone 9. The minimum width of the landing zone is 2.75 meters and the maximum width is 3 meters. If possible, the approach should be in the center of the landing zone, so that the center line of the approach coincides with the center line of the landing zone when it is extended. 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 achieve the above purpose (see Attached Garden) 10. The landing area should be filled with soft and moist sand with a minimum depth of 30 cm, and the sand surface should be flush with the springboard.
