The high jump is made over a crossbar between rigid uprights. The crossbar is raised after each round, and competitors remain in the competition until eliminated by three consecutive failures.

Shoes Heel spikes and plastic heel cups are recommended when jumping for height.

Uprights must be rigid and should extend at least 10cm (4in) above the maximum height to which the crossbar can be raised.
They may be moved only if the take-off or landing area has become unsuitable, and then only with the judges’ agreement and at the end of a round.

Crossbar supports must face the opposite upright and be flat or rectangular.

The crossbar must be circular.
Each end of the bar will have a flat or concave surface for the purpose of placing the bar on the supports.
It must weigh not more than 2kg (4lb 6 1/2oz).
There must be a gap of at least 10mm (1/2in) between the ends of the crossbar and the uprights and the crossbar must rest on the uprights in such a way that, if touched by a competitor, it falls easily
forward or backward to the ground.
The crossbar must always be replaced with the same surfaces facing upward and forward.
