Equipment

Advantages

High jump

Alloyed metal crossbar will not break or hurt the athlete if it falls.

Crossbar will be equal height above ground along its length allowing fair competition and measurement.

Softer landing allows greater heights to be surmounted safely.

Pole vault

Alloyed metal crossbar as above.

Fibreglass in the pole itself gives even more bend and thus allows for a higher hand hold. This allows the athlete to gain greater heights.

Long jump

Take-off board electronics, containing many minerals, allow more accurate measurements.

Less chance of fouling with foot over the line.

Triple jump

As above

Shot put

Iron or brass shots can be accurately made to specified shapes and weights, making competition fair, and maximising equipment quality for the athletes.

The throwing circle surface is made from a firm but non-slippery material, and its ring is strong and durable metal (iron or steel)

Discus

As above for the construction of the discus, plus the steel rim will not be damaged each time the discus lands, and the fibreglass inserts add strength without too much weight.

As above for the throwing circle.

The fibre cord or steel wire cage is strong and minimises dangerous rebound of the object.

Hammer Throw

As above for the construction of the hammer, plus the steel wire attaching the handle is strong but not stretchable.

As above for the throwing circle.

As above for the cage.

Javelin

As above for the construction of the javelin.

The introduction of aluminium made it easier to throw further.

Steel tip penetrates ground easily.
