A football, soccer ball, or association football ball is the ball used in the sport of association football. The name of the ball varies according to whether the sport is called "football", "soccer", or "association football". The ball's spherical shape, as well as its size, weight, and material composition, are specified by Law 2 of the Laws of the Game maintained by the International Football Association Board. Additional, more stringent, standards are specified by FIFA and subordinate governing bodies for the balls used in the competitions they sanction.

Association football Team field sport

Association football, more commonly known as football or soccer, is a team sport played with a spherical ball between two teams of eleven players. It is played by 250 million players in over 200 countries and dependencies, making it the world's most popular sport. The game is played on a rectangular field called a pitch with a goal at each end. The object of the game is to score by moving the ball beyond the goal line into the opposing goal.

The names of association football are the terms used to describe association football, the sport most commonly referred to in the English-speaking world as "football" or "soccer".

The Laws of the Game (LOTG) are the codified rules that help define association football. They are the only rules of association football subscribed to by FIFA. The laws mention the number of players a team should have, the game length, the size of the field and ball, the type and nature of fouls that referees may penalise, the frequently misinterpreted offside law, and many other laws that define the sport. During a match, it is the task of the referee to interpret and enforce the Laws of the Game.

Early footballs began as animal bladders or stomachs that would easily fall apart if kicked too much. Improvements became possible in the 19th century with the introduction of rubber and discoveries of vulcanization by Charles Goodyear. The modern 32-panel ball design was developed in 1962 by Eigil Nielsen, and technological research continues today to develop footballs with improved performance. The 32-panel ball design was soon overcome by 24-panel balls as well as 42-panel balls, both of which improved performance compared to before, in 2007.[ citation needed ]

Charles Goodyear American inventor

Charles Goodyear was an American self-taught chemist and manufacturing engineer who developed vulcanized rubber, for which he received patent number 3633 from the United States Patent Office on June 15, 1844.

Eigil Louis Marius Ferdinand Nielsen, known simply as Eigil Nielsen was a Danish amateur football goalkeeper, who played 28 games for the Denmark national football team and won a bronze medal with Denmark at the 1948 Summer Olympics. He played his club football with KB.

A black-and-white patterned truncated icosahedron design, brought to prominence by the Adidas Telstar, has become an icon of the sport. [1] Many different designs of balls exist, varying both in appearance and physical characteristics. [2]

History

First years of football codes

In the year 1863, the first specifications 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. [3] 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 have been to do with the material used in their creation.

A football is a ball inflated with air that is used to play one of the various sports known as football. In these games, with some exceptions, goals or points are scored only when the ball enters one of two designated goal-scoring areas; football games involve the two teams each trying to move the ball in opposite directions along the field of play.

The Football Association governing body of association football in England

The Football Association (FA) is the governing body of association football in England, the Crown dependencies of Jersey, Guernsey, and the Isle of Man. Formed in 1863, it is the oldest football association in the world and is responsible for overseeing all aspects of the amateur and professional game in its territory.

The International Football Association Board (IFAB) is the body that determines the Laws of the Game of association football. IFAB was founded in 1886 to agree standardised Laws for international competition, and has since acted as the "guardian" of the internationally used Laws; since its establishment in 1904 FIFA, the sport's top governing body, has recognised IFAB's jurisdiction over the Laws. IFAB is known to take a highly conservative attitude regarding changes to the Laws of the Game.

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. [4] 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.

Vulcanisation

In 1838, Charles Goodyear introduced vulcanized rubber, which dramatically improved the football. [5] Vulcanisation is the treatment of rubber to give it certain qualities such as strength, elasticity, and resistance to solvents. Vulcanisation of rubber also helps the football resist moderate heat and cold. Vulcanisation 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 balls of this time had tanned leather with eighteen sections stitched together. These were arranged in six panels of three strips each. [6] [7]

Reasons for improvement

During the 1900s, footballs were made out of leather with a lace of the same material (known as tiento in Spanish) used to stitch the panels. [8] Although leather was perfect for bouncing and kicking the ball, 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. By around 2017, this had also been associated with dementia in former players. [9] Another problem of early footballs was that they deteriorated quickly, as the leather used in manufacturing the footballs varied in thickness and in quality. [6]

The ball without the leather lace was developed and patented by Romano Polo, Antonio Tossolini and Juan Valbonesi in 1931 in Argentina. [10] [11] This innovative ball (named Superball) would be adopted by the Argentine Football Association as the official ball for its competitions since 1932. [12]

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 utilised isotropic material properties but included an additional stiffer stitching seam region.

Future developments

Companies such as Umbro, Mitre, Adidas, Nike, Select and Puma are releasing footballs made out of new materials which are intended to provide more accurate flight and more power to be transferred to the football. [13] [14]

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. [4] Some premium-grade 32-panel balls use non-regular polygons to give a closer approximation to sphericality. [15] The inside of the football is made up of a latex bladder which enables the football to be pressurised. The ball's panel pairs are stitched along the edge; this procedure can either be performed manually or with a machine. [5] The size of a football 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 π gives about 22 cm for a diameter.

The ball's weight must be in the range of 410 to 450 grams (14 to 16 oz) and inflated to a pressure of between 0.6 and 1.1 standard atmospheres (8.8 and 16.2 psi) at sea level. [16]

There are a number of different types of football balls depending on the match and turf including training footballs, match footballs, professional match footballs, beach footballs, street footballs, indoor footballs, turf balls, futsal footballs and mini/skills footballs. [17]

Suppliers

Many companies throughout the world produce footballs. [18] The earliest balls were made by local suppliers where the game was played. It is estimated that 55% of all footballs are made in Sialkot, Pakistan, with other major producers being China and India. [19]

As a response to the problems with the balls in the 1962 FIFA World Cup, Adidas created the Adidas Santiago [20] – 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 for the Olympic Games. [21] They also supply the ball for the UEFA Champions League which is called the Adidas Finale.

FIFA World Cup

In early FIFA World Cups, match balls were mostly provided by the hosts from local suppliers. Records indicate a variety of models being used within individual tournaments and even, on some occasions, individual games. Over time, FIFA took more control over the choice of ball used. Since 1970 Adidas have supplied official match balls for every tournament. [22]

Adidas Predator are a range of football boots developed by German sportswear manufacturers Adidas based on a prototype concept from the Australian former footballer Craig Johnston. The common feature of the Predator range is the presence of rubber patches or strips on the top of the shoe, designed to increase friction between the boot and the ball. In late 2010, Adidas designed the new "Power-spine" technology, which they claim improves shot power by reducing the amount the foot bends back as it kicks the ball.

Basketball (ball) spherical inflated ball

A basketball is a spherical ball used in basketball games. Basketballs typically range in size from very small promotional items only a few inches in diameter to extra large balls nearly a foot in diameter used in training exercises. For example, a youth basketball could be 27 inches (69 cm) in circumference, while a National Collegiate Athletic Association (NCAA) men's ball would be a maximum of 30 inches (76 cm) and an NCAA women's ball would be a maximum of 29 inches (74 cm). The standard for a basketball in the National Basketball Association (NBA) is 29.5 inches (75 cm) in circumference and for the Women's National Basketball Association (WNBA), a maximum circumference of 29 inches (74 cm). High school and junior leagues normally use NCAA, NBA or WNBA sized balls.
