Ice skating is the self-propulsion of a person across a sheet of ice, using metal-bladed ice skates to glide on the ice surface. This activity can be carried out for various reasons, including recreation, sport, exercise, and travel. Ice skating may be performed on specially prepared ice surfaces (arenas, tracks, parks), both indoors and outdoors, as well as on naturally occurring bodies of frozen water, such as ponds, lakes and rivers.



Early history of ice skating

Research suggests that the earliest ice skating happened in southern [Finland] more than 4,000 years ago. This was done to save energy during winter journeys. True skating emerged when a steel blade with sharpened edges was used. Skates now cut into the ice instead of gliding on top of it. Adding edges to ice skates was invented by the Dutch in the 13th or 14th century. These ice skates were made of steel, with sharpened edges on the bottom to aid movement. [1]

The fundamental construction of modern ice skates has stayed largely the same since then, although differing greatly in the details, particularly in the method of binding and the shape and construction of the steel blades. In the Netherlands, ice skating was considered proper for all classes of people, as shown in many pictures by the Old Masters.

Ice skating was also practiced in China during the Song dynasty, and became popular among the ruling family of the Qing dynasty. [2]

Rising popularity and first clubs

Ice skating was brought to Britain from the Netherlands, where James II was briefly exiled in the 17th century. When he returned to England, this 'new' sport was introduced to the British aristocracy, and was soon enjoyed by people from all walks of life.[ citation needed ]

The first organised skating club was the Edinburgh Skating Club, formed in the 1740s, (some claim the club was established as early as 1642). [3] [4] [5]

An early contemporary reference to the club appeared in the second edition (1783) of the Encyclopædia Britannica:

The metropolis of Scotland has produced more instances of elegant skaters than perhaps any country whatever: and the institution of a skating club about 40 years ago has contributed not a little to the improvement of this elegant amusement. [3]

From this description and others, it is apparent that the form of skating practiced by club members was indeed an early form of figure skating rather than speed skating. For admission to the club, candidates had to pass a skating test where they performed a complete circle on either foot (e.g., a figure eight), and then jumped over first one hat, then two and three, placed over each other on the ice. [3]

On the Continent, participation in ice skating was limited to members of the upper classes. Emperor Rudolf II of the Holy Roman Empire enjoyed ice skating so much, he had a large ice carnival constructed in his court in order to popularise the sport. King Louis XVI of France brought ice skating to Paris during his reign. Madame de Pompadour, Napoleon I, Napoleon III and the House of Stuart were, among others, royal and upper class fans of ice skating.

The next skating club to be established was in London and was not founded until 1830. [3] By the mid-19th century, ice skating was a popular pastime among the British upper and middle classes—Queen Victoria became acquainted with her future husband, Prince Albert, through a series of ice skating trips [6] —and early attempts at the construction of artificial ice rinks were made during the "rink mania" of 1841–44. As the technology for the maintenance of natural ice did not exist, these early rinks used a substitute consisting of a mixture of hog's lard and various salts. An item in the 8 May 1844 issue of Littell's 'Living Age' headed the 'Glaciarium' reported that "This establishment, which has been removed to Grafton street East' Tottenham Court Road, was opened on Monday afternoon. The area of artificial ice is extremely convenient for such as may be desirous of engaging in the graceful and manly pastime of skating".

Emergence as a sport

Skating became popular as a recreation, a means of transport and spectator sport in The Fens in England for people from all walks of life. Racing was the preserve of workers, most of them agricultural labourers. It is not known when the first skating matches were held, but by the early nineteenth century racing was well established and the results of matches were reported in the press. [7] Skating as a sport developed on the lakes of Scotland and the canals of the Netherlands. In the 13th and 14th centuries wood was substituted for bone in skate blades, and in 1572 the first iron skates were manufactured. [8] When the waters froze, skating matches were held in towns and villages all over the Fens. In these local matches men (or sometimes women or children) would compete for prizes of money, clothing or food. [9]

The winners of local matches were invited to take part in the grand or championship matches, in which skaters from across the Fens would compete for cash prizes in front of crowds of thousands. The championship matches took the form of a Welsh main or "last man standing" contest. The competitors, 16 or sometimes 32, were paired off in heats and the winner of each heat went through to the next round. A course of 660 yards was measured out on the ice, and a barrel with a flag on it placed at either end. For a one-and-a-half mile race the skaters completed two rounds of the course, with three barrel turns. [9]

In the Fens skates were called pattens, fen runners, or Whittlesey runners. The footstock was made of beechwood. A screw at the back was screwed into the heel of the boot, and three small spikes at the front kept the skate steady. There were holes in the footstock for leather straps to fasten it to the foot. The metal blades were slightly higher at the back than the front. In the 1890s, fen skaters started to race in Norwegian style skates.

On Saturday 1 February 1879, a number of professional ice skaters from Cambridgeshire and Huntingdonshire met in the Guildhall, Cambridge, to set up the National Skating Association, the first national ice skating body in the world. [10] The founding committee consisted of several landowners, a vicar, a fellow of Trinity College, a magistrate, two Members of Parliament, the mayor of Cambridge, the Lord Lieutenant of Cambridge, journalist James Drake Digby, the president of Cambridge University Skating Club, and Neville Goodman, a graduate of Peterhouse, Cambridge (and son of Potto Brown's milling partner, Joseph Goodman). [11] The newly formed Association held their first one-and-a-half-mile British professional championship at Thorney in December 1879.

Figure skating

The first instructional book concerning ice skating was published in London in 1772. The book, written by a British artillery lieutenant, Robert Jones, describes basic figure skating forms such as circles and figure eights. The book was written solely for men, as women did not normally ice skate in the late 18th century. It was with the publication of this manual that ice skating split into its two main disciplines, speed skating and figure skating.

The founder of modern figure skating as it is known today was Jackson Haines, an American. He was the first skater to incorporate ballet and dance movements into his skating, as opposed to focusing on tracing patterns on the ice. Haines also invented the sit spin and developed a shorter, curved blade for figure skating that allowed for easier turns. He was also the first to wear blades that were permanently attached to the boot.

The International Skating Union was founded in 1892 as the first international ice skating organisation in Scheveningen, in the Netherlands. The Union created the first codified set of figure skating rules and governed international competition in speed and figure skating. The first Championship, known as the Championship of the Internationale Eislauf-Vereingung, was held in Saint Petersburg in 1896. The event had four competitors and was won by Gilbert Fuchs. [12]

Physical mechanics of skating

A skate can glide over ice because there is a layer of ice molecules on the surface that are not as tightly bound as the molecules of the mass of ice beneath. These molecules are in a semiliquid state, providing lubrication. The molecules in this "quasi-fluid" or "water-like" layer are less mobile than liquid water, but are much more mobile than the molecules deeper in the ice. At about −157 °C (−250 °F) the slippery layer is one molecule thick; as the temperature increases the slippery layer becomes thicker. [13] [14] [15] [16] [17]

It had long been believed that ice is slippery because the pressure of an object in contact with it causes a thin layer to melt. The hypothesis was that the blade of an ice skate, exerting pressure on the ice, melts a thin layer, providing lubrication between the ice and the blade. This explanation, called "pressure melting", originated in the 19th century. This, however, did not account for skating on ice temperatures lower than −3.5 °C, whereas skaters often skate on lower-temperature ice. [18]

In the 20th century, an alternative explanation, called "friction melting", proposed by Lozowski, Szilder, Le Berre, Pomeau and others showed that because of the viscous frictional heating, a macroscopic layer of melt ice is in-between the ice and the skate. With this they fully explained the low friction with nothing else but macroscopic physics, whereby the frictional heat generated between skate and ice melts a layer of ice [19] [20] [21] . This is a self-stabilizing mechanism of skating. If by fluctuation the friction gets high, the layer grows in thickness and lowers the friction, and if it gets low, the layer decreases in thickness and increases the friction. The friction generated in the sheared layer of water between skate and ice grows as √V with V the velocity of the skater, such that for low velocities the friction is also low.

Whatever the origin of the water layer, skating is more destructive than simply gliding. A skater leaves a visible trail behind on virgin ice and skating rinks have to be regularly resurfaced to improve the skating conditions. It means that the deformation caused by the skate is plastic rather than elastic. The skate ploughs through the ice in particular due to the sharp edges. Thus another component has to be added to the friction: the “ploughing friction”. [21] [22] The calculated frictions are of the same order as the measured frictions in real skating in a rink. [23] The ploughing friction decreases with the velocity V , since the pressure in the water layer increases with V and lifts the skate (aquaplaning). As a result the sum of the water-layer friction and the ploughing friction only increases slightly with V, making skating at high speeds (>90 km/h) possible.

Inherent safety risks

A person's ability to ice skate depends on the roughness of the ice, the design of the ice skate, and the skill and experience of the skater. While serious injury is rare, a number of short track speed skaters have been paralysed after a heavy fall when they collided with the boarding. A fall can be fatal if a helmet is not worn to protect against severe head trauma. Accidents are rare but there is a risk of injury from collisions, particularly during hockey games or in pair skating.

A significant danger when skating outdoors on a frozen body of water is falling through the ice into the freezing water underneath. Death can result from shock, hypothermia or drowning. It is often difficult or impossible for the skater to climb out of the water, due to the weight of their ice skates and thick winter clothing, and the ice repeatedly breaking as they struggle to get back onto the surface. Also, if the skater becomes disoriented under the water, they might not be able to find the hole in the ice through which they have fallen. Although this can prove fatal, it is also possible for the rapid cooling to produce a condition in which a person can be revived up to hours after falling into the water.

Communal activities on ice

A number of recreational and sporting activities take place on ice.

Broomball and curling are also played on ice but the players are not required to wear ice skates.

Winter sports sport mainly practiced during the wintertime, often on snow or ice

Winter sports or winter activities are competitive sports or non-competitive recreational activities which are played on snow or ice. Most are variations of skiing, ice skating and sledding. Traditionally, such games were only played in cold areas during winter, but artificial snow and artificial ice allow more flexibility. Artificial ice can be used to provide ice rinks for ice skating, ice hockey, and bandy in a milder climate.

Inline skating is a multi-disciplinary sport and can refer to a number of activities practiced using inline skates. Inline skates typically have two to five polyurethane wheels, arranged in a single line by a metal or plastic frame on the underside of a boot. The in-line design allows for greater speed and maneuverability than traditional roller skates. Following this basic design principle, inline skates can be modified to varying degrees to accommodate niche disciplines.

An ice rink is a frozen body of water and/or hardened chemicals where people can ice skate or play winter sports. Besides recreational ice skating, some of its uses include ice hockey, bandy, rink bandy, ringette, broomball, speed skating, figure skating, ice stock sport and curling as well as exhibitions, contests and ice shows. There are two types of rinks in prevalent use today: natural, where freezing occurs from cold ambient temperatures, and artificial, where a coolant produces cold temperatures in the surface below the water, causing the water to freeze. There are also synthetic ice rinks where skating surfaces are made out of plastics.

Ice resurfacer vehicle or hand-pushed device used to clean and smooth the surface of an ice sheet

An ice resurfacer is a vehicle or hand-pushed device used to clean and smooth the surface of a sheet of ice, usually in an ice rink. The first ice resurfacer was developed by American inventor and engineer Frank Zamboni in 1949 in the city of Paramount, California. As such, an ice resurfacer is often referred to as a "Zamboni" regardless of brand or manufacturer.

Regelation is the phenomenon of melting under pressure and refreezing when the pressure is reduced. We can demonstrate regelation by looping a fine wire around a block of ice, with a heavy weight attached to it. The pressure exerted on the ice slowly melts it locally, permitting the wire to pass through the entire block. The wire's track will refill as soon as pressure is relieved, so the ice block will remain solid even after wire passes completely through. This experiment is possible for ice at −10 °C or cooler, and while essentially valid, the details of the process by which the wire passes through the ice are complex. The phenomenon works best with high thermal conductivity materials such as copper, since latent heat of fusion from the top side needs to be transferred to the lower side to supply latent heat of melting. In short, the phenomenon in which ice converts to liquid due to applied pressure and then re-converts to ice once the pressure is removed is called regelation.

Premelting refers to a quasi-liquid film that can occur on the surface of a solid even below melting point. The thickness of the film is temperature dependent. This effect is common for all crystalline materials. Premelting shows its effects in frost heave, the growth of snowflakes and, taking grain boundary interfaces into account, maybe even in the movement of glaciers.

It used to be thought ... that the reason skaters can glide gracefully across the ice is because the pressure they exert on the sharp blades creates a thin layer of liquid on top of the ice... More recent research has shown, though, that this property isn't why skaters can slide on the ice... It turns out that at the very surface of the ice, water molecules exist in a state somewhere between a pure liquid and a pure solid. It's not exactly water -- but it's like water. The atoms in this layer are 100,000 times more mobile than the atoms [deeper] in the ice, but they're still 25 times less mobile than atoms in water. So it's like proto-water, and that's what we're really skimming on.
