Description of high jump facilities

HIGH JUMP FACILITY

Layout

The High Jump facility includes a runway a take-off area two uprights with crossbar and a landing area.By temporarily removing sections of the kerb, it is possible to use the oval track as part of the runway.For major championshipsthe High Jump facility must be large enough so that two High Jumps can be conducted simultaneously.

Runway

The minimum width of High Jump runway shall be 16m and the minimum length of the runway shall be 15m except for major international competitions where the minimum length shall be 25m but preferably longer centred midway between the uprights.

The maximum allowance for the overall downward inclination of the runway in the running direction shall not exceed 1:167(0.6%)when measured along a 15m radius of the 16m wide runway area centred midway between the uprights. The take- off area shall be level or inclined not more than 1:167(0.6%).

If it is necessary to remove the kerb temporarily in order to be able to use the oval track as a runway, care must be taken to ensure that the heights of the surfaces of the oval track and the segment are the same along the track border.The runway and take-off areas are usually covered with the same surface as the track.

For many competitions, itis necessary to conduct two High Jumps simultaneously under similar conditions.This can best be achieved by havingtwo High Jump runways on the "D” symmetrically placed about a central Javelin Throw runway with the spacing between the two sets of High Jump uprights being between 12m and 15m.This is illustrated on Figure 2.5a.

Uprights

The High Jump uprights must be installed 4.02m ± 0.02m apart.

Landing Mats

The High Jump landing mats shall measure not less than 6.00mx4.00m and shall be covered by a spike proof protective mat.The overall height shall be minimum

0.70m. lt may be placed on a 0.10m high qrid which, on all sides, should be boarded to the ground with its front edge 0.10m behind that of the mat.

The landing mats should be placed so that the athlete's approach is up the inclination of the runway.

Safety

Of particu ar importance for the safety of the Hiah Jump is a suitabe andina mat which will allow both sufficient absorption of the impact energy from the fall of the athletes and gives adequate resillience when compressed.The condition of the landing mat must be reqularly monitored.

If the oval track is included in the runwaya removable kerb is essential

Suitability for Competition and Official Acceptance

High Jump facilities must conform to the specifications. This can be established when inspecting the 400m Standard Track.
