বরফ স্কেটিং
বরফ স্কেটিং হলো বরফ স্কেট ব্যবহার করে বরফের উপর চলাফেরা করার একটি উপায়। এটি অনেক কারনেই করা হয়ে থাকে, এর মধ্যে রয়েছে ব্যায়াম, অবকাশের জন্য, ভ্রমণ, এবং বিভিন্ন ক্রীড়া। বরফ স্কেটিং করা যায় বিশেষ ভাবে প্রস্তুতকৃত বরফের পৃষ্ঠতলের উপর (থিয়েটার, ট্র্যাক, উদ্যান) এবং স্বাভাবিকভাবেই বরফ হওয়া পানিতে (যেমনঃ পুকুর, হ্রদ এবং নদী)। বরফের পৃষ্ঠতল ইনডোর এবং আউটডোর, উভয়ই হতে পারে।
A study by Federico Formenti of the University of Oxford suggests that the earliest ice skating happened in southern Finland more than 3,000 years ago. Originally, skates were merely sharpened, flattened bone strapped to the bottom of the foot. Skaters did not actually skate on the ice, but rather glided on top of it. 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. The construction of modern ice skates has stayed largely the same since then. 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 practised in China during the Song dynasty, and became popular among the ruling family of the Qing dynasty.
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.
The first organised skating club was the Edinburgh Skating Club, formed in the 1740s, (some claim the club was established as early as 1642).
An early contemporary reference to the club appeared in the second edition (1783) of the Encyclopædia Britannica:
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.
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. By the mid-19th century, ice skating was a popular pastime among the British upper and middle classes, (Queen Victoria got to know her future husband, Prince Albert, through a series of ice skating trips.) 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".
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. 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. 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.
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.
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. 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 fellow of Peterhouse College (and son of Potto Brown’s milling partner, Joseph Goodman). The newly formed Association held their first one-and-a-half-mile British professional championship at Thorney in December 1879.
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.
For a time, the stiff and rigid British figure skating forms dominated in America, trumping Haines's more artistic way of skating. Haines instead attempted to spread his innovations in ice skating style in Europe, gaining success in such countries as Sweden and Austria. His style was still opposed by both his American colleagues as well as skaters from Victorian England, who continued to advocate a stiffer and more restrained style of skating. Haines continued to add new dance elements to his routines, and astounded a crowd in Vienna in the winter of 1868. Many in the audience expressed wonder at how a normal man could move over the ice in such a manner. Haines's performance led to the establishment of the Vienna School, which continued to develop Haines's artistic style.
The International Skating Union was founded in 1892 as the first international ice skating organization 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.
A skate can slide over ice because the ice molecules at the surface cannot properly bond with the molecules of the mass of ice beneath and thus are free to move like molecules of liquid water. These molecules remain in a semiliquid state, providing lubrication.
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. In the 20th century, an alternative explanation, called "friction heating", was proposed, whereby friction of the material was causing the ice layer melting. However, this theory also failed to explain skating at low temperature. In fact, neither explanation explained why ice is slippery when standing still even at below-zero temperatures.
Skating 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 skaters have been paralysed after a fall when they hit the boarding. Falling can be fatal if a helmet is not worn to protect against serious head trauma. Accidents are rare but most common with collisions, hockey games, or pair skating.
The second, and more serious, danger is falling through the ice into the freezing water underneath when skating outdoors on a frozen body of water. Death can occur due to shock, hypothermia or drowning. It is often difficult or impossible for skaters to climb out of the water back onto the ice due to the ice repeatedly breaking, the skater being weighed down by skates and thick winter clothing, or the skater becoming disoriented under water. The skater may even not be able to find the hole through which they fell. This may result in drowning or hypothermia, but the rapid cooling can also create a state in which someone can be revived up to hours after having fallen in the water. For safety, it is recommended that skaters should never skate alone or in darkness and that they should bring nails or ice-claws when they are skating on a lake or river to allow them to get a grip on the ice and pull themselves out of the water if they fall through the ice.
