In association football, the football (alternatively "football ball" or soccer ball according to whether the game is referred to as "football" or "soccer") used in official matches is a specific type of football standardised for size, weight, and material and manufactured to the specifications of the Laws of the Game, specifically Law 2.

Early footballs began as animal bladders that would easily fall apart if kicked too much. As time went on, footballs developed into what they look like today. This was possible with the help of people like Charles Goodyear and Domenico Nobili, who introduced rubber and their discoveries of vulcanization to the design of footballs. Today, technological research is ongoing to develop footballs with improved performance.

History

Leather ball used in the football tournament at the 1936 Summer Olympics.

In 1863, the first specification for footballs were laid down by the Football Association. Previous to this, footballs were made out of inflated leather, with later leather coverings to help footballs maintain their shapes.[1] In 1872 the specifications were revised, and these rules have been left essentially unchanged as defined by the International Football Association Board. Differences in footballs created since this rule came into effect has been to do with the material used in their creation.

Footballs have gone through a dramatic change over time. During medieval times balls were normally made from an outer shell of leather filled with cork shavings.[2] Another method of creating a ball was using animal bladders for the inside of the ball making it inflatable. However, these two styles of creating footballs made it easy for the ball to puncture and were inadequate for kicking. It was not until the 19th century that footballs developed into what a football looks like today.

Vulcanization

In 1838, Charles Goodyear and Domenico Nobili introduced the use of rubber and their discoveries of vulcanization, which dramatically improved the football.[3] Vulcanization is the treatment of rubber to give it certain qualities such as strength, elasticity, and resistance to solvents. Vulcanization of rubber also helps the football resist moderate heat and cold. Vulcanization helped create inflatable bladders that pressurize the outer panel arrangement of the football. Charles Goodyear's innovation increased the bounce ability of the ball and made it easier to kick. Most of the balls of this time had tanned leather with eighteen sections stitched together. These were arranged in six panels of three strips each.[4]

Reasons for improvement

During the 1900s, footballs were made out of rubber and leather which was perfect for bouncing and kicking the ball; however, when heading the football (hitting it with the player's head) it was usually painful. This problem was most probably due to water absorption of the leather from rain, which caused a considerable increase in weight, causing head or neck injury. Another problem of early footballs was that they deteriorated quickly, as the leather used in manufacturing the footballs varied in thickness and in quality.[4]

Present developments

Elements of the football that today are tested are the deformation of the football when it is kicked or when the ball hits a surface. Two styles of footballs have been tested by the Sports Technology Research Group of Wolfson School of Mechanical and Manufacturing Engineering in Loughborough University; these two models are called the Basic FE model and the Developed FE model of the football. The basic model considered the ball as being a spherical shell with isotropic material properties. The developed model also utilized isotropic material properties but included an additional stiffer stitching seam region.

Future developments

Companies such as Mitre, Adidas, Nike and Puma are releasing footballs made out of new materials which promise more accurate flight and more power to be transferred to the football.[5]

Construction

Today’s footballs are more complex than past footballs. Most modern footballs consist of twelve regular pentagonal and twenty regular hexagonal panels positioned in a truncated icosahedron spherical geometry.[2] The inside of the football is made up of a latex bladder which enables the football to be pressurized. The ball’s panel pairs are stitched along the edge; this procedure can either be performed manually or with a machine.[3] The size of a soccer ball is roughly 22 cm (8.65 inches) in diameter for a regulation size 5 ball. Rules state that a size 5 ball must be 68 to 70 cm in circumference. Averaging that to 69 cm and then dividing by pi gives about 22 cm for a diameter.

Suppliers

Many companies throughout the world produce footballs. 75% of all footballs are made in Sialkot, Pakistan.[6] The earliest balls were made by local suppliers where the game was played. As a response to the problems with the balls in the 1962 FIFA World Cup] Adidas created the Adidas Santiago [7] - this led to Adidas winning the contract to supply the match balls for all official FIFA and UEFA matches, which they have held since the 1970s, and also supplied match balls for the 2008 Olympic Games.[8] They also supply the ball for the UEFA Champions League which is called the Adidas Finale.

FIFA World Cup

The following footballs were used in the FIFA World Cup finals tournaments:

World Cup Ball(s) Image Manufacturer Additional information Refs
1930 Two different balls were used in the final: Argentina supplied the first-half ball (the 'Tiento') and led 2–1 at the break; hosts Uruguay supplied the second-half ball (the 'T-Model' which was larger and heavier) [7] and won 4–2. [7][9]
1934 Federale 102 ECAS (Ente Centrale Approvvigionamento Sportivi), Rome [10]
1938 Allen, Paris [11]

The Crack was the official ball. Referee Ken Aston was unimpressed with the Chilean ball provided for the opening match, and sent for a European ball, which arrived in the second half. Various matches used different balls, with the apparent rumour the European teams didn't trust the locally produced ball [7] [7][9][14][16]
