All sports are deposits of history. In the course of historical development, many sports are moving towards scientific and rational, and human nature is changing.
The sport we want to talk about today has a long history, and it is a technical and complex competitive sport - high jump. But what I want to say here is the assistant equipment "high jump pole" used in high jump.
The high jump pole, which is a pole for jumpers to jump over a high railing, has changed a lot in the development of history.
- wooden pole
The use of wooden poles began in Ireland in 554 A.D. and became a true track and field sport in England in 1843. The wooden poles used at that time had many shortcomings. If the high jump wanted to cross the railings easily, it needed a certain amount of run-up and flexibility of the high jump poles.
At that time, the wooden pole was not only very elastic, but also easy to break, which was not conducive to high jump.
- Bamboo pole
The emergence of bamboo poles has changed this situation. Bamboo pole has a certain elasticity, which also promotes the development of elevation movement. But the bamboo pole is easy to break, once the bending degree of the bamboo pole is too large and the weight of the athletes is too heavy, it is very easy to break.

- Metal rod
The appearance of metal pole makes up for the shortcomings of bamboo pole, which is not easy to break and has certain elasticity. With the increase of the holding point of the high jumper, the bending range of the metal pole increases, so the elasticity increases.
In 1957 and 1960, American athletes B. Gutovsky and D. Bragg set new world records through metal poles. Metal poles play a milestone role in the development of high jump, but they have not been popularized.
- fiberglass rod
Fiberglass rod is the last stage of the development of high jump pole. The advantage of fiberglass rod is that its strength is very high and its elasticity is very good. As long as the movements are mastered properly, the high jump with fiberglass pole can create very good results. American athletes B. Stonberg and J. Pennell have jumped 5.13 meters and 5.20 meters successively.
Fiberglass pole is also the standard high jump pole used in the international high jump movement at present. The appearance of fiberglass pole has greatly promoted the development of high jump. The performance of high jump has also been greatly improved by the use of fiberglass rods.

所有的体育运动项目都是历史的沉淀物，在历史的发展过程中，很多体育运动都朝着科学合理，人性化在转变。
今天所要说的这项运动有着悠久的历史，并且是一项技术性复杂的竞技运动——跳高运动。但是这里要说的是跳高运动所使用辅助器材“跳高杆”。
跳高杆，这就是一根为了撑起跳高运动员越过具有一高度栏杆的杆子，但就是这样一根杆子在历史的发展中发生了很大的改变。
- 木制竿
木制竿的使用早在公元554年的爱尔兰就开始了，真正成为一项田径运动是从1843年的英国。当时所使用的木杆缺点非常多，跳高运动想要轻松跨越栏杆那就需要一定的助跑加跳高杆具有一定的弹性。
而当时的木制竿不仅弹性非常小，而且还很容易折断，非常不利于跳高。
04
- 竹竿
竹竿的出现改了这一现状。竹竿拥有一定的弹性，这也推进了调高运动的发展。但是竹竿还是容易折断，一旦竹竿的弯曲程度过大再加上运动员体重过重是非常容易折断的。
- 金属杆
金属杆的出现了弥补了竹竿的缺点，金属杆不容易折断，且具有一定的弹性。随着跳高运动员提高握竿点之后，金属杆弯曲的幅度也增大，这样弹性也会增大。
1957年和1960年，通过金属竿，美国运动员B.古托夫斯基和D.布雷格分别创造了新的世界记录。金属杆对于跳高运动的发展有着里程碑的作用，但金属杆并未普及开来。
- 玻璃纤维竿
玻璃纤维竿是跳高杆发展的最后一个阶段，玻璃纤维杆的好处在于强度非常大，且弹性非常的好。只要动作掌握得当，通过玻璃纤维竿跳高可以创造出非常好的成绩，美国运动员B.斯顿伯格和J.彭内尔先后跃过5.13米和5.20米。
玻璃纤维杆也是目前国际调高运动所使用的标准跳高杆，玻璃纤维竿的出现更是极大的推动了跳高运动的发展。跳高运动的成绩也因为玻璃纤维杆而大幅度提升。
