Figure skating
Figure skating is a sport in which individuals, pairs, or groups perform on figure skates on ice. It was the first winter sport to be included in the Olympic Games, when contested at the 1908 Olympics in London. The Olympic disciplines are men's singles, women's singles, pair skating, and ice dance; the four individual disciplines are also combined into a team event, first included in the Winter Olympics in 2014. The non-Olympic disciplines include synchronized skating, Theater on Ice, and four skating. From intermediate through senior-level competition, skaters generally perform two programs (the short  program and the free skate), which, depending on the discipline, may include spins, jumps, moves in the field, lifts, throw jumps, death spirals, and other elements or moves. Figure skaters compete at various levels from beginner up to the Olympic level (senior) at local, regional, sectional, national, and international competitions. The International Skating Union (ISU) regulates international figure skating judging and competitions. These include the Winter Olympics, the World Championships, the World Junior Championships, the European Championships, the Four Continents Championships, the Grand Prix series (senior and junior), and the ISU Challenger Series. The sport is also associated with show  business. Major competitions generally conclude with exhibition galas, in which the top skaters from each discipline perform non-competitive programs. Many skaters, both during and after their competitive careers, also skate in ice shows, which run during the competitive season and the off-season. Terminology. The term "professional" in skating refers not to skill level but competitive status. Figure skaters competing at the highest levels of international competition are not "professional" skaters. They are sometimes referred to as amateurs, though some earn money. Professional skaters include those who have lost their ISU eligibility and those who perform only in shows . They may also include former Olympic and World champions who have ended their competitive career, as well as skaters with little or no international competitive experience. In addition to performing in ice shows, professional skaters often compete in professional competitions, which are held throughout the world, each with its own format and rules. In languages other than English, Japanese, Korean, Chinese, Italian, Polish and Russian, figure skating is usually referred to by a name that translates as "artistic skating". Figure skates. The most visible difference to ice hockey skates is that figure skates have a set of large, jagged teeth  called "toe picks" on the front part of the blade. These are used primarily in jumping and should not be used for stroking or spins. If used during a spin, the toe pick will cause the skater to lose momentum, or move away from the center of the spin. Blades are mounted to the sole and heel of the boot with screws. Typically, high-level figure skaters are professionally fitted for their boots and blades at a reputable skate shop. Professionals are also employed to sharpen blades to individual requirements. Blades are about thick. When viewed from the side, the  blade of a figure skate is not flat, but curved slightly, forming an arc of a circle with a radius of . This curvature is referred to as the "rocker" of the blade. The "sweet spot" is the part of the blade on which all spins are rotated; this is usually located near the stanchion of the blade, below the ball of the foot. The blade is also "hollow ground"; a groove on the bottom of the blade creates two distinct edges, inside and outside. The inside edge of the blade is on the side closest to the skater; the outside  edge of the blade is on the side farthest from the skater. In figure skating, it is always desirable to skate on only one edge of the blade. Skating on both at the same time (which is referred to as a "flat") may result in lower skating skills scores. The apparently effortless power and glide across the ice exhibited by elite figure skaters fundamentally derives from efficient use of the edges to generate speed. Skates used in singles and pair skating have a set of large, jagged teeth called a "toe pick" on the front of each blade. The toe  picks are mainly used to help launch the skater into the air for the take-off when performing jumps. Ice dance blades have smaller toe picks than blades used for the other disciplines. During a spin, skaters use the "sweet spot" of the blade, which is one of two rockers to be found on a blade and is the roundest portion of the blade. The sweet spot is located just behind the toe pick and near the middle of the blade. The other rocker is the more general curvature of the blade when stroking or gliding. Ice dancers' blades are  about an inch shorter in the rear than those used by skaters in other disciplines, to accommodate the intricate footwork and close partnering in dance. Dancers' blades also have a smaller toe pick as they do not require the large toe pick used for jumping in the other disciplines. Hard plastic "skate guards" are used when the skater must walk in his or her skates when not on the ice, to protect the blade from dirt or material on the ground that may dull the blade. Soft blade covers called "soakers" are used to absorb condensation and protect the blades  from rust when the skates are not being worn. In competition, skaters are allowed three minutes to make repairs to their skates. There are many different types of boots and blades to suit different disciplines and abilities. For example, athletes who are performing advanced multi-rotational jumps often need a stiffer boot that is higher and gives more support. Athletes working on single or double jumps require less support and may use a less stiff boot. Ice dancers may prefer a lower cut boot that is designed to enable more knee bend. Likewise, blades designed for free and pairs skating  have a longer tail to assist landing. The blade profile and picks are designed to assist with spinning and with jump entry, take-off, landing and exit. Modern blade technology increasingly uses carbon fibre and materials other than steel to make blades lighter. These materials may also be more flexible and help cushion jump landings and be protective of young athlete's joints. Ice dance blades have short tails to enable close foot work and reduce the risk of blade clash in close complex moves. They may also be thinner to assist with glide and fast changes of edge. Off -ice training is the term for physical conditioning that takes place off the ice. Besides regular physical exercise, skaters do walk-throughs of jumps off the ice to practice sufficient rotation and height of their jumps, and to practice consistency in landing on one foot. In 2020/2021 many athletes relied on a variety of off-ice training and conditioning methods due to rinks being closed due to COVID-19. Ice rinks and rink equipment. There is significant variation in the dimensions of ice rinks. Olympic-sized rinks have dimensions of , NHL-sized rinks are , while European rinks are sometimes . The ISU  prefers Olympic-sized rinks for figure skating competitions, particularly for major events. According to ISU rule 342, a figure skating rink for an ISU event "if possible, shall measure sixty (60) meters in one direction and thirty (30) meters in the other, but not larger, and not less than fifty-six (56) meters in one direction and twenty-six (26) meters in the other." The scoring system rewards skaters who have good ice coverage, i.e. those who efficiently cover the entire ice surface during their programs. Olympic-sized rinks make the differences in skill between skaters more apparent but they  are not available for all events. If a rink has different dimensions, a skater's jump setup and speed may be hindered as he or she adjusts. Ice quality is judged by smoothness, friction, hardness, and brittleness. Factors affecting ice quality include temperature, water quality, and usage, with toe picks causing more deterioration. For figure skating, the ice surface temperature is normally maintained between and , with the Olympic disciplines requiring slightly softer ice (−3.5 °C) than synchronized skating (−5.5 °C). Typically after every two warm-up groups, an ice resurfacer cleans and smooths the surface of the ice  sheet. Inadequate ice quality may affect skaters' performances. Some rinks have a harness system installed to help skaters learn new jumps in a controlled manner. A heavy-duty cable is securely attached to two of the walls around the ice, with a set of pulleys riding on the cable. The skater wears a vest or belt, with a cable or rope attached to it, and the cable/rope is threaded through the movable pulley on the cable above. The coach holds the other end of the cable and lifts the skater by pulling the cable/rope. The skater can then  practice the jump with the coach assisting the completion. This is used when a skater needs more help on a jump. However, if the coaches see fit, they could use another harness usually called "the fishing pole harness." It is named that because it looks similar to a fishing pole. The skater will put on the harness and the coach will adjust it so it fits the skater. The skater will go and do the jump with very little help from their coach. They can also do the jump on any pattern they choose, whereas, the other harness, they must  do in a straight line. Disciplines. Olympic disciplines. As an Olympic sport, figure skating comprises the following disciplines: The four disciplines of men's singles, women's singles, pair skating, and ice dance, are also incorporated into a team event which appeared on the Olympic programme for the first time at the 2014 Winter Olympics. Elements and moves. Each element receives a score according to its base value and grade of execution (GOE), resulting in a combined technical elements score (TES). At competitions, a technical specialist identifies the elements and assigns each one a level of difficulty, ranging from B  (Basic) to Level 4 (most difficult). For each element, a panel of judges determines the GOE, ranging between −5 and +5, according to how well the skater executes the element. The GOE is weighted according to the base value of the element. Through the ISU guidelines skaters must perform a minimum of seven elements in their short program and twelve elements in their long program. The ISU defines a fall as a loss of control with the result that the majority of the skater's body weight is not on the blade but supported by hands, knees, or buttocks. Jumps . Jumps involve the skater leaping into the air and rotating rapidly to land after completing one or more rotations. There are many types of jumps, identified by the way the skater takes off and lands, as well as by the number of rotations that are completed. Each jump receives a score according to its base value and grade of execution (GOE). Quality of execution, technique, height, speed, flow and ice coverage are considered by the judges. An "under-rotated" jump (indicated by < ) is "missing rotation of more than , but less than revolution" and receives 70% of the base value . A "downgraded" jump (indicated by «) is "missing rotation of revolution or more". A downgraded triple is treated as a double jump, while a downgraded double is treated as a single jump. An edge violation occurs when a skater executes a jump on the incorrect edge. The hollow is a groove on the bottom of the blade which creates two distinct edges, inside and outside. The inside edge of the blade is on the side closest to the skater, the outside edge is on the side farthest from the skater, and a "flat" refers to skating on both edges at the  same time, which is discouraged. An unclear edge or edge violation is indicated with an 'e' and reflected in the GOE according to the severity of the problem. "Flutz" and "lip" are the colloquial terms for a Lutz and flip jump with an edge violation. In 1982, the ISU enacted a rule stating that a skater may perform each type of triple only once in a program, or twice if one of them is incorporated into a combination or sequence. For a set of jumps to be considered a "combination", each jump must take off from the landing edge of  the previous jump, with no steps, turns, or change of edge between jumps. Toe loops and loops are commonly performed as the second or third jump in a combination because they take off from the back outside edge of the landing foot, or skating leg. To perform a salchow or flip on the back end of a combination, a half loop (which is actually a full rotation, but lands on a back inside edge of the landing leg) may be used as a connecting jump. In contrast, jump "sequences" are sets of jumps that may be linked by non-listed  jumps or hops. Sequences are worth 80% of the combined value of the same jumps executed in combination. A figure skater only needs to be able to jump in one direction, either clockwise or counter-clockwise. The vast majority of figure skaters prefer to rotate in a counter-clockwise direction when jumping. Thus, for clarity, all jumps will be described for a skater jumping counter-clockwise. There are six jumps in figure skating that count as jump elements. All six are landed on one foot on the back outside edge (with counter-clockwise rotation, for single and multi-revolution jumps ), but have different takeoffs, by which they may be distinguished. Jumps are divided into two different categories: "toe jumps" and "edge jumps". The number of rotations performed in the air determines whether the jump is a single, double, triple, or quadruple (commonly known as a "quad"). The simplest jump is a waltz jump, which can only be done in a half-leap and is not classified as a single, double, or triple jump. Senior-level male single skaters perform mostly triple and quadruple jumps in competition. The only quad not to have been accomplished by a skater in competition is  the quadruple Axel, which involves four and a half rotations. This jump has been attempted in competition but has not been landed successfully. Triple jumps, other than the triple Axel, are commonly performed by female single skaters. It is rare for a female skater to land a quadruple jump, and very few female single skaters have been credited with quads in competition. Some elite skaters can complete a jump in about one second, with 26 inches of height and 10 feet in distance. The takeoff speed of a jump can reach up to 15 mph. Prior to most jumps, a  figure skater needs to skate backward to build power and speed. Toe jumps. Toe jumps are launched by digging the toe pick of one skate into the ice, using it to vault into the air with the opposite leg. The main toe jumps are (in order of score value): All of the above descriptions assume a counter-clockwise direction of rotation, landing backwards on the outside edge of the right foot. (For clockwise rotation, the skater takes off using the alternative foot and lands backwards on the outside edge of the left foot.) Edge jumps. Edge jumps use no toe  assist, and include (in order of score value): Again, these descriptions assume a counter-clockwise direction of rotation, landing backwards on the outside edge of the right foot. (For clockwise rotation, the skater takes off using the alternative foot and always lands backwards on the outside edge of the left foot.) Other jumps. Several other jumps are usually performed only as single jumps and in elite skating are used as transitional movements or highlights in step sequences. These include the half toe loop (ballet jump), half loop, half flip, walley jump, waltz jump, inside Axel, one-foot Axel, stag jump , and split jump. There are two kinds of split jump: Spins. Spins are a required element in all four Olympic disciplines. There are three basic positions – upright, sit and camel – with numerous variations. Spins may be performed individually or in a spin sequence, combining different types of spin; a spin sequence is known as a "combination spin". During a spin, the skater rotates on the front rocker (sometimes called the "sweet spot" or "spin rocker"), which is the curved part of the blade that corresponds to the ball of the skater's foot, just behind the toe pick. A spin  may be executed on the back rocker of the blade during a change of edge spin. For example, a back scratch spin will flip edges to a forward inside edge. This feature of a spin will change the level of a spin. A figure skater only needs to be able to spin in one direction, either clockwise or counterclockwise. Most skaters favor a counter-clockwise direction of rotation when spinning (as in jumping), but some skaters prefer to spin in the clockwise direction. A small minority of skaters can spin in both directions. Spins may be performed on either foot . For skaters who rotate in a counter-clockwise direction, a spin on the left foot is called a forward spin, while a spin on the right foot is called a backspin. The opposite applies to skaters who rotate in a clockwise direction. When learning to spin, a skater will typically learn a forward spin first, then once that is mastered they will learn how to execute a backspin. When performing some types of spin, an elite skater can complete on average six rotations per second, and up to 70 rotations in a single spin. However, this is rarely seen in  modern competitions because it would gain no extra points for the spin. Spins are normally entered on the ice, but they can also be entered from a jump or sequence of jumps known as star jumps. Spins that are entered through a jump are calling flying spins; these include the flying camel, flying sit spin, death drop, and butterfly spin. Flying spins may go from a forward spin to a back spin and they can also be performed as part of a spin sequence (combination spin). In pair skating, spins may be performed side by side with both partners doing  the same spin or combination spin simultaneously. Additionally, in pairs and ice dance, there are pair spins and dance spins, during which both skaters rotate around the same axis while holding onto one another. Lifts. Lifts are a required element in pair skating and ice dance. Pair lifts. Pair lifts are generally overhead. According to the current ISU rules for senior-level competition, the man must rotate more than once, but fewer than three-and-a-half times. In competitive pair skating, lifts must travel across the ice to be included in the technical elements score (TES); stationary lifts are  included in choreography. Pair lifts are grouped by the holds involved. Legal holds: The judges look at speed, ice coverage, the quality of the lady's position, position changes, and the man's stability and cleanness of turns throughout. Skaters may also raise their score by having a difficult entry such as in spiral or spread eagle position, a difficult exit, or other features such as stopping the rotation, turning a carry lift into rotational one, or reversing rotation (i.e. both clockwise and counter-clockwise directions). This gives the lifts a level. They can be from a base level to  a level 4. The higher the level, the more points the skaters can receive. Twist lifts are a form of pair lifts, where the lifted partner is thrown into the air, twists, and is caught by the lifted partner. The lady is caught by her waist in the air and lands on the backward outside edge. Some pairs include a split before rotating. This is credited as a difficult feature if each leg is separated by at least a 45° angle from the body axis and the legs are straight or almost straight. Scores are also affected by the  height of the twist, turns, steps or other moves before the element, the lady holding her arms over her head, delayed rotation, etc. This element is also a leveled element. Dance lifts. Ice dancers are not allowed to lift their partners above their shoulders. Dance lifts are separated into "short lifts" and "long lifts". There are many positions each partner can take to raise the difficulty of a lift. Each position must be held for at least three seconds to count and is permitted only once in a program. Short lifts may last up to six seconds in competition on  the senior level. Long lifts may last up to ten seconds in competition on the senior level. In both pairs and dance, lifts that go on longer than allowed receive deductions. Skating skills, turns, steps, moves in the field, and other moves. Along with other forms of skating, figure skating is one of the only human powered activities where travelling backwards is integral to the discipline. The ability to skate well backwards and forwards are considered to be equally important, as is the ability to transition well between the two. Step sequences are a required element in all four Olympic  disciplines. The pattern can be straight line, circular, or serpentine. The step sequence consists of a combination of turns, steps, hops and edge changes. Additionally, steps and turns can be used as transitions between elements. The various turns, which skaters can incorporate into step sequences, include: Choctaws are the two-foot equivalents of rockers and counters. Other movements that may be incorporated into step sequences or used as connecting elements include lunges and spread eagles. An Ina Bauer is similar to a spread eagle performed with one knee bent and typically an arched back. Hydroblading refers to a deep edge  performed with the body as low as possible to the ice in a near-horizontal position. Moves in the field is a pre-determined required sequence that demonstrated basic skating skills and edge control. In the context of a competitive program, they include sequences that may include spirals, spread eagles, Ina Bauers, hydroblading, and similar extended edge moves, along with loops, twizzles, and different kinds of turns. A spiral is an element in which the skater moves across the ice on a specific edge with the free leg held at hip level or above. Spirals are distinguished by the edge  of the blade used (inside or outside), the direction of motion (forward or backward), and the skater's position. A spiral sequence is one or more spiral positions and edges done in sequence. Judges look at the depth, stability, and control of the skating edge, speed and ice coverage, extension, and other factors. Some skaters can change edges during a spiral, i.e. from inside to outside edge. Spirals performed on a "flat" are generally not considered as true spirals. Spiral sequences were required in women's and pair skating prior to the 2012–13 season, but from the 2012–13 season onward , they were replaced by the choreographic sequence. The choreographic sequence consists of moves in the field, unlisted jumps, spinning movements, etc. and is required for the men's, women's and pair free program. A death spiral is a required element of pair skating. There are four varieties distinguished by the lady's edge and direction of motion. The man performs a pivot, one toe anchored in the ice, while holding the hand of his partner, who circles him on a deep edge with her body almost parallel to the ice. As of 2011, the woman's head must at  some time reach her skating knee. The man must also be in a full pivot position and the death spiral must be held for a minimum amount of rotation, depending on the level. Compulsory figures. Compulsory figures involves using the blades of the figure skates to draw circles, figure eights, and similar shapes on the surface of the ice. Skaters are judged on the accuracy and clarity of the figures and the cleanness and exact placement of the various turns on the circles. Figures were formerly included as a component of singles competitions but were eliminated from international events in  1990. The United States was the last country to retain a separate test and competitive structure for compulsory figures, but the last national-level figures championship was held in 1999. "Moves in the field" (known in the United Kingdom as "field moves") replaced compulsory figures as a discipline to teach the same turns and edge skills. The World Figure Sport Society, based in Lake Placid, NY, hosts an annual World Figure Championship, which was first held in 2015. This event acts to preserve the historic origins of figure skating, offering a perfect black ice surface on which the compulsory figures  competition is held. Competition format and scoring. The ISU is the governing body for international competitions in figure skating, including the World Championships and the figure skating events at the Winter Olympic Games. Medals are awarded for overall results; the standard medals are gold for first place, silver for second, and bronze for third place. U.S. Figure Skating also awards pewter medals for fourth-place finishers in national events. Additionally, at the World, European, Four Continents, and World Junior Championships, the ISU awards "small medals" for segment results (short and free program). A medal is generally attributed to only one  country, even if a partnership is composed of skaters with different nationalities. A notable exception was the pair skating partnership between Ludowika Eilers and Walter Jakobsson; their 1910–11 medals were attributed to both Germany and Finland. Beyond the early 20th century, no skaters have been allowed to represent two countries in the same competition. In singles and pairs figure skating competition, competitors perform two programs: the short program, in which they complete a set of required elements consisting of jumps, spins and steps; and the free skate, also known as the "long program", in which they have a slightly wider  choice of elements. Under both the 6.0 system and the ISU Judging System, the judges consider the "complete package" when evaluating performances, i.e. the best jumper is not always placed first if the judges consider the difference in jumping execution to be outweighed by another skater's speed, spins, presentation, etc. Ice dance competitions formerly consisted of three phases: one or more compulsory dances; an original dance to a ballroom rhythm that was designated annually; and a free dance to music of the skaters' own choice. Beginning in the 2010–11 season, the compulsory and original dances were merged into the  short dance, which itself was renamed the "rhythm dance" in June 2018, before the 2018–19 season. 6.0 System. Skating was formerly judged for "technical merit" (in the free skate), "required elements" (in the short program), and "presentation" (in both programs). The marks for each program ran from 0.0 to 6.0, the latter being the highest. These marks were used to determine a preference ranking (or "ordinal") separately for each judge; the judges' preferences were then combined to determine placements for each skater in each program. The placements for the two programs were then combined, with the free skate placement weighted  more heavily than the short program. The highest placing individual (based on the sum of the weighted placements) was declared the winner. ISU Judging System. In 2004, in response to the judging controversy during the 2002 Winter Olympics, the ISU adopted the International Judging System (IJS), which became mandatory at all international competitions in 2006, including the 2006 Winter Olympics. The new system is sometimes informally referred to as the "Code of Points", however, the ISU has never used the term to describe their system in any of their official communications. Under the IJS, points are awarded individually for each  skating element, and the sum of these points is the "total element score" (TES). Competitive programs are constrained to include a set number of elements. Each element is judged first by a technical specialist who identifies the specific element and determines its "base value". This is done using instant replay video to verify features that distinguish different elements; e.g. the exact foot position at take-off and landing of a jump. A panel of twelve judges then each award a mark for the quality and execution of the element. This mark, called the "grade of execution" (GOE), is an integer  with a minimum value of −5 and a maximum value of +5. The GOE mark is then translated into another value by using the table of values in ISU rule 322. The GOE value from the twelve judges is then processed with a computerized random selection of nine judges, the highest and lowest values are then discarded, and finally the average of the remaining seven is calculated. This average value is then added to (or subtracted from) the base value to determine the total value for the element. Note: The IJS previously used a GOE scale of −3 to +3  but this was changed for the 2018–19 season and is in the early stages of being tested in competitions. The "program components score" (PCS) awards points to holistic aspects of a program or other nuances that are not rewarded in the "total element score". The components are: A detailed description of each component is given in ISU rule 322.2. Judges award each component a raw mark from 0 to 10 in increments of 0.25, with a mark of 5 being defined as "average". For each separate component, the raw marks are then selected, trimmed, and averaged in a manner akin  to determining a "grade of execution". The trimmed mean scores are then translated into a factored mark by multiplying by a factor that depends on the discipline, competition segment, and level. Then the five (or four) factored marks are added to give the final PCS score. The "total element score" and the "program components score" are added to give the total score for a competition segment (TSS). A skater's final placement is determined by the total of their scores in all segments of a competition. No ordinal rankings are used to determine the final results. Other judging and competition . There are also skating competitions organized for professional skaters by independent promoters. These competitions use judging rules set by whoever organizes the competition. There is no "professional league". Well-known professional competitions in the past have included the World Professional Championships (held in Landover, Maryland), the Challenge Of Champions, the Canadian Professional Championships and the World Professional Championships (held in Jaca, Spain). The Ice Skating Institute (ISI), an international ice rink trade organization, runs its own competitive and test program aimed at recreational skaters. Originally headquartered in Minnesota, the organization now operates out of Dallas, Texas. ISI competitions are open  to any member that have registered their tests. There are very few "qualifying" competitions, although some districts hold Gold Competitions for that season's first-place winners. ISI competitions are especially popular in Asian countries that do not have established ISU member federations. The Gay Games have also included skating competitions for same-gender pairs and dance couples under ISI sponsorship. Other figure skating competitions for adults also attract participants from diverse cultures. World standings and season's bests. World standings. The world standing (WS) of a skater/couple is calculated based on the results over the current and preceding  two seasons. Competitors receive points based on their final placement at an event and the event's weight. The following events receive points: Following the current season's World Championships, the results from the earliest season are deleted. A new partnership starts with zero points; there is no transfer of WS points if a pair or ice dance couple split up and form a new partnership. These standings do not necessarily reflect the capabilities of the skater(s). Due to limits on entries to events (no more than three from each country), and varying numbers of high-level skaters in each  country, skaters from some countries may find it more difficult to qualify to compete at major events. Thus, a skater with a lower SB but from a country with few high-level skaters may qualify to a major event while a skater with a much higher SB but from a country with more than three high-level skaters may not be sent. As a result, it is possible for a skater who regularly scores higher to end up with a much lower world standing. The "season's world ranking" of a skater/couple is calculated similarly to the overall world  standing but is based on the results of the ongoing season only. Season's bests. The season's best (SB) of a skater/couple is the highest score achieved within a particular season. There is an SB for the combined total score and the individual segment scores (short program/rhythm dance, free skating/free dance). Only scores achieved at selected international competitions are considered; scores from national competitions and some international events are disregarded. The best combined total for each skater or couple appears on a list of season's bests, and the list may be used to help determine  participants in the following season's Grand Prix series. Skaters and couples also have personal best (PB) scores, i.e. the highest scores achieved over their entire career, in terms of combined total and segment scores. However, PB scores are not completely comparable if achieved in different seasons because the ISU regulations and technical rules are modified before each new season. There may be different requirements specified to achieve a certain level; the required elements may change and new elements may be allowed (for example, two quads in the short program were permitted starting in the 2010–11 season); and the point  values may change (for example, the values of quads were increased after the 2010 Olympics, and a second step sequence is no longer assigned a level in the men's competition). As a result of these variations in the technical requirements, the ISU places more weight on the season's bests, which are fully comparable within any one season. Music and clothing. Music. For competitive programs, figure skaters were once restricted to instrumental music; vocals were allowed only if they contained no lyrics or words. Beginning in the 1997–98 season, the ISU decided to allow lyrics or words in ice  dance music. Although the rules were not relaxed for singles and pairs, judges did not always penalize violations. At the 2011 World Championships, Florent Amodio's long program music included words but an insufficient number of judges voted for a deduction. In June 2012, the ISU voted to allow skaters from all disciplines to choose music with words in their competitive programs beginning in the 2014–15 season. Skaters may use professional music editors so that their music meets requirements. Ice dancers are required to skate to music that has a definite beat or rhythm. Singles and pair skaters more often  skate to the melody and phrasing of their music. For long programs, figure skaters generally search for music with different moods and tempos. Music selections for exhibitions are less constrained than for competitive programs. Clothing. Skaters are generally free to select their own attire, with a few restrictions. In competition, females may wear a dress, typically with matching attached briefs, and since 2004, they may also choose trousers. They may wear opaque flesh-colored leggings or tights under dresses and skirts, which may extend to cover their skates. Men must wear trousers – they are not allowed to wear tights, although , officials do not always impose a deduction for violations. Matching costumes are not required in pair skating and ice dance. Competition costumes vary widely, from simple designs to heavily beaded or trimmed costumes. Skaters risk a deduction if a piece of their costume falls onto the ice surface. An official may stop a program if he or she deems there to be a hazard. Skaters and family members may design their own costumes, sometimes with assistance from their coach or choreographer, or turn to professional designers. Costumes may cost thousands of dollars if designed by a top-level costume maker . This rule of costuming came after Katarina Witt's costume and performance at the 1988 Winter Olympics. According to current ISU regulations, costumes in competition must be fair, non-revealing, and appropriate for both short and long programs. Costumes should not be showy or exotic in nature. Clothing, however, can reflect the genre of music chosen. Although the use of flesh-colored fabric means the costumes are often less revealing than they may appear, there have been repeated attempts to ban clothing that gives the impression of "excessive nudity" or that is otherwise inappropriate for athletic competition. In general, accessories  or props are not permitted in competition. The ISU allowed an exception for the original dance in the 2007–08 season but not since. Eligibility. Age eligibility. To compete internationally on the senior level, skaters must be at least 15 before July 1 of the preceding year. To be eligible for junior-level events, a skater must be at least 13 but under 19 before that date (or 21 for male pair skaters and ice dancers). A skater must meet the age requirement "before" it becomes July 1 in their place of birth. For example, Adelina Sotnikova was born a few  hours into July 1, 1996, in Moscow and consequently, was not eligible to compete at Junior Worlds until 2011 and senior Worlds until 2013. The ISU's rules apply to international events. Many countries have no age requirements for domestic non-ISU competitions, thus, some skaters compete at the senior level nationally while not eligible for international competition. The ISU has modified its age rules several times. Before the 1990s, 12 was the minimum age for senior international competitions. New rules were introduced in 1996, requiring skaters to be at least 15 before July 1 of the preceding year to  compete at the Olympics, Worlds, Europeans, or Four Continents. The minimum age for all other senior internationals was 14 until July 2014, when it was raised to 15. During the 2005–06 season, Mao Asada of Japan was age-eligible to compete at the Grand Prix Final, where she claimed the title, but she was not permitted to compete at the Olympics. For the 2008 World Championships, the United States was obliged to send skaters who had placed 5th and 7th at nationals because higher-placed skaters were too young, including a skater who missed the cutoff by 20 days. The  ISU has strictly enforced the rules in recent years. However, American pair skater Natasha Kuchiki was allowed to compete at the 1990 World Championships when she was two years too young and American single skater Tara Lipinski, who was 13 at the time the 1996 rules were introduced, was grandfathered into remaining eligible for future events, along with other skaters who had already competed at the World Championships. A loophole also existed for a few years for underage skaters who had medaled at Junior Worlds. As in gymnastics, skating has experienced controversy surrounding possible age falsification. On February 14, 2011 , questions emerged surrounding nine Chinese skaters. The Associated Press found that birthdates listed on the Chinese Skating Association's website suggested five female skaters, Sui Wenjing, Zhang Dan, Yu Xiaoyu, Geng Bingwa, and Xu Binshu, were younger than their ISU ages, and four male skaters, Han Cong, Zhang Hao, Jin Yang, and Gao Yu, were older. The dates disappeared from the website by February 15. On February 17, the ISU said there were no discrepancies for Zhang Dan, Zhang Hao, and Xu Binshu between the birthdates listed on their passports, ISU registration forms and the Chinese Olympic Committee's website . Athletes in China sometimes face pressure to falsify their age. Other eligibility rules. Skaters may represent a country of which they are not yet a citizen in most competitions, except the Olympics which require citizenship. At most international events, each country may send one to a maximum of three entries per discipline. Consequently, even if a skater has a high season's best, he or she may not be sent to major events if their country has many good skaters in their discipline. Some skaters have tried to circumvent this by representing another country. In response, the ISU introduced rules  barring skaters from international events for a certain period of time. In the 2010 regulations, it was 24 months or more from the date of the last ISU Championship. In the 2012 regulations, the minimum was 18 months for singles and 12 months for pairs/ice dancers from the date of their last ISU Championships (Worlds, Europeans, Four Continents, Junior Worlds) and 12 months if they competed in some other international competition. Competitors may sit out for much longer because they also have to obtain a release from their previous federation. The ISU has set no limit to how long  a country may hold skaters. Skaters may lose their ISU eligibility if they perform in an unsanctioned show or competition. Beginning in the 2010–11 season, minimum scores were introduced for the World, European, or Four Continents Championships. In the 2011–12 season, different minimum scores were introduced for the Grand Prix series. Competitors' expenses, income, and funding. Figure skating is an expensive sport. This is particularly due to the costs of ice time and coaching. In the late 1980s, the expenses of a top-ten women's competitor at the U.S. Championships reached nearly US$50,000 a year. In October 2004 , a U.S. Figure Skating article estimated the annual expense at US$9,000–$10,000 for pre-juvenile, US$18,000 for juvenile, US$35,000–$40,000 for novice, and said junior and senior levels were somewhat more expensive. In the 2010s, American senior national medalists had expenses in the mid-five-figure range. Swiss skater Stéphane Lambiel said his costs were around CHF 100,000 per season. World champion Patrick Chan's expenses were Can$150,000. In 2015, CBC Sports estimated that a Canadian pair team had expenses of about Can$100,000 per year. Prize money is relatively low compared to other sports. A men's or women 's singles skater who won the 2011 World Championships earned US$45,000, about 1.8% to 2.5% of the US$1,800,000–$2,400,000 for winners of the tennis US Open and Australian Open. A couple who won the pairs or ice dance title split US$67,500. A winner of the senior Grand Prix Final in December 2011 earned US$25,000. Some national associations provide funding to some skaters if they meet certain criteria. Many skaters take part-time jobs and some have tried crowdfunding. In Germany, many elite skaters join the army to fund their skating. In Italy, some skaters join police agencies ' sport groups, such as the Polizia Penitenziaria's "Fiamme Azzurre" (Carolina Kostner, Anna Cappellini, Luca Lanotte) or Polizia di Stato's "Fiamme Oro" (Federica Faiella, Paolo Bacchini). Some competitive skaters depend on income from shows. Shows must be sanctioned by their association, i.e. skaters may lose their competitive eligibility if they take part without permission. In some cases, skaters may feel pressure to compete through injury to be allowed to perform in a show. Others may become involved with coaching younger athletes in order to fund their own training costs. Injuries and health issues. Competitive skaters generally do not wear  helmets or other protective gear. There is a risk of head injuries, particularly in pair skating as a result of falls from lifts. Although pair skaters are most susceptible, serious head injuries can occur in all disciplines, including ice dance. Partners have accidentally slashed each other with their skate blades. This may occur when partners drift too close during side-by-side camel spins. Several female pair skaters have suffered head/face injuries during this element, including Elena Berezhnaya, Jessica Dubé, Mandy Wötzel, Galina Maniachenko (Efremenko), and Elena Riabchuk. Commenting on falls and concussions, Madison Hubbell said that "Most of  the time, the worst falls are on things we kind of take for granted." Shin splints, knee injuries, and back problems are not uncommon. Hip damage may occur as a result of practising jumps and throws. In rare cases, intensive training of spins may result in subtle concussions (Lucinda Ruh). Injuries have also been sustained by skaters from different teams when many skaters are practising on the ice. Midori Ito collided with Laetitia Hubert at the 1991 World Championships, while Oksana Baiul and Tanja Szewczenko collided at the 1994 Olympics, but all went on to compete. On practice sessions with  multiple skaters on the ice, the skater whose music is playing conventionally has right of way. Also, pairs and ice dancers skating as a unit have right of way over those skating separately as changing course is more difficult for a couple. In some countries, medical personnel may be slow to respond to accidents. At the 2000 World Championships in Nice, France, a pair skater who had been injured in a lift accident lay on the ice for several minutes and had to get up and leave the ice on his own before being offered medical attention. Eating disorders are  reportedly common in figure skating. Body image and the need to maintain a fit body is a very common issue in figure skating, as skaters age, their bodies change and change the way they must approach the sport. Skaters such as Gracie Gold, and Ashley Wagner have faced issues such as eating disorders and depression. Figure skaters occasionally have positive doping results but it is not common. Commenting on Soviet skaters, three-time Olympic champion Irina Rodnina stated in 1991, "Boys in pairs and singles used drugs, but this was only in August or September. This was done just in  training, and everyone was tested (in the Soviet Union) before competitions." History. Although people have been ice skating for centuries, figure skating in its current form originated in the mid-19th century. "A Treatise on Skating" (1772) by the accomplished skater, Welshman Lt. 'Captain' Robert Jones (c.1740–c.1788), is the first-known book on figure skating. He designed skates that could be attached to shoes by screws through the heels (rather than using straps), and these were soon available from Riccard's Manufactory in London. Competitions were held in the "English style" of skating, which was stiff and formal and bore  very little resemblance to modern figure skating. Without changing the basic techniques used by skaters, only a limited number of figure skating moves could be performed. This was still true in the mid-1800s before improvements were brought about by American skater Jackson Haines, who was considered to be the "father of modern figure skating". In the mid-1860s, Haines introduced a new style of skating, incorporating free and expressive techniques, which became known as the "international style". Although popular in Europe, the international style of skating was not widely adopted in the United States until long after Haines' death. Early 1900s . The International Skating Union was founded in 1892. The first European Figure Skating Championships were held in 1891 in Hamburg, Germany (won by Oskar Uhlig), and the first World Figure Skating Championships were held in 1896 in Saint Petersburg, Russia (won by Gilbert Fuchs). Only men competed in the early events but in 1902 a woman entered the World Championships for the first time: British female skater Madge Syers competed in the men's competition, finishing in second place behind Sweden's Ulrich Salchow. The ISU quickly banned women from competing against men, and established a separate "ladies" competition in  1906. Pair skating was introduced at the 1908 World Championships, where the title was won by Anna Hübler and Heinrich Burger of Germany. Figure skating was the first winter sport contested at the Olympics; it made its Olympic debut at the 1908 Summer Olympics in London. On March 20, 1914, an international figure skating championship was held in New Haven, Connecticut. This event was the forerunner of both the United States and Canadian National Championships. However, international competitions in figure skating were interrupted by World War I. In the 1920s and 1930s, figure skating was dominated by Sonja Henie of  Norway. Henie turned competitive success into a lucrative professional career as a movie star and touring skater, also setting the fashion for female skaters to wear short skirts and white boots. The top male figure skaters of this period included Sweden's Gillis Grafström and Austria's Karl Schäfer. After World War II. Skating competitions were again interrupted for several years by World War II. After the war, with many European rinks in ruins, skaters from the United States and Canada began to dominate international competitions and to introduce technical innovations to the sport. Dick Button, 1948 and 1952 Olympic  Champion, was the first skater to perform the double Axel and triple loop jumps, as well as the flying camel spin. The World Figure Skating Championships did not include ice dance until 1952. In its early years, ice dance was dominated by British skaters, and until 1960 the world title was won every year by a British couple, beginning with Jean Westwood and Lawrence Demmy. On February 15, 1961, the entire U.S. figure skating team and their coaches were killed in the crash of Sabena Flight 548 in Brussels, Belgium en route to the World Championships in Prague. This tragedy  sent the U.S. skating program into a period of rebuilding. Meanwhile, the Soviet Union rose to become a dominant force in the sport, especially in the disciplines of pair skating and ice dance. At every Winter Olympics from 1964 until 2006, a Soviet or Russian pair won gold in pair skating, in what is often considered to be one of the longest winning streaks in modern sports history. The 1967 World Championships was the last event held on an outdoor rink. Effect of television and the present day. Compulsory figures formerly accounted for up to 60% of the score in  singles figure skating, meaning that skaters who could build up a significant lead in figures could win competitions even if they were mediocre free skaters. As television coverage of skating events became more important, the popularity of free skating increased because this part of the competition was televised and shown to the general public, whereas the compulsory figures competition was not. The television audience would complain when superior free programs sometimes failed to equate to gold medal victories. Beginning in 1968, the ISU progressively reduced the weighting of compulsory figures and introduced the short program in 1973. A critical issue  was said to have been the continued failure of Janet Lynn to achieve on the world stage despite her outstanding free skate programs. For example, she missed out on a podium place at the 1971 World Championships after winning the free skate competition decisively, which produced an uproar and loud booing from the audience during the medal ceremony. With these changes, the emphasis in competitive figure skating shifted to increased athleticism. Landing triple jumps during the short program and the free skate became more important. By the 1980s, some skaters began practising quadruple jumps. Jozef Sabovcik of Czechoslovakia landed a  quad toe loop at the 1986 European Championships which was recognized at the event but then ruled invalid three weeks later due to a touchdown with his free foot. At the 1988 World Championships, Kurt Browning of Canada landed the first quad toe loop which has remained ratified. Despite expectations, it was several years before quads became an important part of men's skating. In 1988, Japan's Midori Ito became the first woman to land a triple Axel, pushing the athletic and technical level for women's programs. Worth only 20% by 1989, compulsory figures were eliminated from international  competition in 1990. Television contributed to the sport's popularity by showing skaters in the kiss and cry area after competing. Television also played a role in removing the restrictive amateur status rules that once governed the sport. In May 1990, the ISU voted to allow skaters intending to skate professionally to return to ISU competition, provided that they obtained their national association's permission. In 1995, in an effort to retain skaters who might otherwise have given up their eligibility to participate in lucrative professional events, the ISU introduced prize money at its major competitions, funded by revenues from  selling the TV rights to those events. In 1984, more than 24 million people in Great Britain watched ice dance pair Jayne Torvill and Christopher Dean earn unanimous 6.0s for presentation, the only perfect score in Olympic skating history, which was ranked the 8th greatest sporting moment in a UK poll. In the 1993 National Sports Study II, considered by the Associated Press as the largest study of spectator sport popularity in America, women's figure skating was the second most popular spectator sport in America, just behind NFL football out of over 100 sports surveyed. The 1993 study found  that three figure skaters – Dorothy Hamill, Peggy Fleming, and Scott Hamilton – were among the eight most popular athletes in the United States, of more than 800 athletes surveyed. Dorothy Hamill was statistically tied with Mary Lou Retton as the most popular athlete in America. The Tonya Harding scandal in 1994 increased interest in figure skating. The first night of the women's figure skating competition in the 1994 Winter Olympics achieved higher Nielsen TV ratings than the Super Bowl three weeks earlier and, to that date, was the most watched sports television program of all time. To show support, spectators  sometimes throw a variety of items onto the ice after the end of a figure skating program, most commonly stuffed toys and flowers. Officials discourage people from throwing flowers that are not fully wrapped because of the possibility of debris disrupting or endangering the following skaters. Countries that have produced a great many successful skaters include Russia and the former Soviet Union, the United States, Canada, Japan, China, France, Germany, and Italy. While the sport has grown in East Asia, training opportunities in South Asia are limited due to a scarcity of ice rinks. India had only four major indoor  ice rinks as of 2011, but there were plans for ten more to be built, mostly in malls, over the following five years. As of 2016, three of these intended ten indoor rinks were built at Neptune Magnet Mall, Atria Millennium Mall, and Lulu Mall respectively. Four skating has mostly disappeared, while synchronized skating, singles/pair skating and ice dance have grown. On April 6, 2011, the International Olympic Committee officially confirmed the approval of a figure skating team event, which was introduced at the 2014 Winter Olympics. The elimination of the compulsory dance segment provided space for the team  event. Each team is composed of a men's and women's singles skater, a pair, and an ice dance duo. A maximum of ten teams can compete, with five eliminated after the short program. In December 2011, the ISU released details of the qualifying system and the competition.
