Pole vault

Athletes use a long pole to jump high. They try to clear a bar. This sport is called the pole vault.

Long ago, people used poles to jump over ditches. Ancient Greeks used them to jump over objects. Today, poles are made of glass fiber. This helps them bend.

Jumpers must be fast and strong. They also need great skill. Some great jumpers were gymnasts. They use speed to fly high. It is a very exciting sport!

Pole vaulting is a track and field sport. Athletes use a long, flexible pole to jump over a bar. This sport needs speed, strength, and skill. Many top vaulters were also gymnasts.

People have used poles for a long time. Ancient Egyptians used spears to cross ditches. Ancient Greeks used poles to jump over objects. In the 1790s, a German teacher named Johann Christoph Friedrich GutsMuths helped start modern pole vaulting. He wrote rules for the sport.

In the past, poles were made of wood. They used ash or hickory. Later, they used bamboo, steel, or aluminum. Now, most poles are made of fiberglass or carbon fiber.

These new materials help the pole bend.

In a contest, vaulters try to clear a bar at a certain height. They get three tries at each height. If they miss three times in a row, they are out. The highest height they cleared is their score. If there is a tie, they may have a jump-off. This is a sudden contest to find the winner.

Pole vaulting is an exciting track and field event. Athletes use a long, flexible pole to help them jump over a high bar. This sport is very special because it requires unique equipment. To do well, a vaulter needs speed, strength, and agility. Many elite athletes even have backgrounds in gymnastics.

This helps them with the skill needed to move through the air. It is one of the four major jumping events in athletics.

In a competition, the athlete follows a specific set of steps. First, they run down a path toward a metal pit called a box. They place the pole into this box to start their jump. The athlete can choose where to place the bar, which sits on upright stands. After the jump, the vaulter must clear the bar without knocking it down. If the pole hits the bar and knocks it off, it is a foul. If the pole breaks, it is called an equipment failure.

People have used poles for thousands of years.

Ancient Egyptians used spears to cross irrigation ditches. Ancient Greeks used poles to jump over various objects. Between 1800 BC and 550 BC, the Irish may have used poles in the Tailteann Games. Modern pole vaulting began in the 1790s with a German teacher named Johann Christoph Friedrich GutsMuths. He is often called the father of the sport. He wrote down the first rules for jumping and hand grips.

Technology has changed the poles used in the sport. Early poles were made of ash or hickory wood. In 1904, athletes began using bamboo poles. After 1945, aluminum and steel poles became common. In the 1960s, fiberglass poles became very popular. For example, John Uelses set a world record with a fiberglass pole in 1962. Today, many poles are made of carbon fiber. This material was introduced to the sport in 2007.

Rules help make the competition fair for everyone.

Each vaulter gets three attempts to clear a specific height. If they miss three times in a row, they are out. They can also choose to "pass" a height to try a higher one. If two people tie, they might have a jump-off. A jump-off is a sudden contest to find a winner. The athletes try the same height until one person clears it and the other misses. This ensures there is always a clear winner.

Pole vaulting, also known as pole jumping, is a specialized track and field event. In this sport, an athlete uses a long, flexible pole to help them jump over a horizontal bar. It is classified as one of the four major jumping events in athletics. These events include the high jump, long jump, and triple jump. Unlike many other track events, pole vaulting requires significant specialized equipment. To succeed, a vaulter must possess a combination of speed, agility, and strength. Many elite vaulters, such as world record breakers Yelena Isinbayeva and Brian Sternberg, have backgrounds in gymnastics. This training provides the physical attributes necessary for the technical demands of the sport.

The mechanism of a vault involves several precise steps. An athlete begins by running down a runway toward a metal pit called a box. The pole is placed into this box to initiate the takeoff. The athlete must use the pole to propel themselves upward and over a bar. This bar sits on upright supports known as standards. A vaulter can choose the horizontal position of these standards before each jump. This allows them to place the bar at a specific distance beyond the back of the box. The athlete must clear the bar without dislodging it from the uprights.

Modern competitions follow strict rules to ensure fairness. Each athlete can choose the height at which they enter the competition. Once they begin, they are allowed three attempts to clear a specific height. If they succeed, they advance to the next, higher level. If an athlete misses three consecutive attempts, they are out of the competition. This failure to clear any height is often recorded as a "no height," or NH. Athletes may also choose to "pass" certain heights to save energy for higher ones. However, passing affects how many attempts they have left at subsequent heights.

The history of pole jumping stretches back to ancient civilizations. As early as 2500 BC, ancient Egyptians used spears to mount enemy structures or cross irrigation ditches. Greek vases and pots show that locals used poles to jump over objects. Between 1800 BC and 550 BC, a sport similar to pole vaulting was likely part of the Irish Tailteann Games. Modern pole vaulting, however, is an athletic contest where height is measured. This was established in the 1790s by the German teacher Johann Christoph Friedrich GutsMuths. He is considered the father of the modern sport because he defined jumping standards and hand grips.

Technology has drastically changed the materials used for poles. Originally, athletes used poles made of ash or hickory wood. Bamboo poles were introduced in 1904, followed by aluminum and steel after 1945. The 1960s saw a major shift with the rise of fiberglass poles. In 1962, John Uelses used a fiberglass pole to set a new world record. By 1963, the world record was surpassed twice within just nine days using this material. More recently, carbon fiber poles were introduced in 2007 to further advance the sport.

Manufacturing these poles is a complex engineering process. For example, fiberglass poles can be made using a mandrel, which is a metal tube. Glass fibers impregnated with resin are wound around this mandrel and then baked in an oven. Once cooled, the mandrel is removed, leaving a hollow tube. In 2008, a patent was granted for "Carbon Weave," a method of winding fibers in different directions. This allows manufacturers to provide specific properties to different parts of the pole. Because stiffness and length are vital, elite vaulters may carry up to ten different poles to a single competition.

If two vaulters finish with the same height, specific rules determine the winner. First, officials look at the number of misses at the final height cleared. If they are still tied, they count the total number of misses in the entire competition. In some cases, a jump-off is held to break the tie. A jump-off is a sudden-death competition where vaulters attempt the same height. They take only one attempt each, and the height is adjusted until one person clears and the other misses. This ensures a definitive result for the competition.
