The word pole can be defined in two ways, the first is to refer to a large rod that ends in a metal point at one end, used mainly to move or guide animals in the field. On the other hand, there is the pole or pole, which is a long and flexible rod that is used by athletes during the practice of pole vaulting, this rod allows them to gain momentum to jump over a bar placed several meters high.

The pole used in the sport is a bar whose dimension is between 4 and 5 meters. Throughout the history of athletics, the poles have been made of various materials, at first they were made of inelastic materials, such as metal and wood, then they were made of bamboo, this material caused a lot of furor within the pole vault practice since it could be bent. It was not until the sixties when the pole made with carbon fiber began to be used, this material gave the bar incredible flexibility, later bars made of carbon fiber and fiberglass were made, where the central part of the rod was made of fiberglass, so that it would be more flexible in that area, and the ends were made of carbon fiber, since in this part so much elasticity was not necessary.

The poles are numbered to be able to distinguish them. For example, the first numbers reflect the length of the pole, and it is measured in meters, that is, it represents the length from one end of the pole to the other, the second number represents the resistance of the pole, and it is measured in pounds, indicating the maximum weight that can be supported by the pole. In order to determine said weight, preliminary tests are carried out where weights are placed on it until it breaks. The third number represents the flexibility and is measured in millimeters, this number indicates the effort that has to be made so that the rod bends more or less.

For example, a 3`30/180/20 pole would be a pole that measures 3.30 meters and is the most recommended to carry a weight limit of 180 pounds (81.6 kg) and when adding the standard weight, bows at 20 mm.
