Figure skating is a sport in which individuals, pairs, or groups perform jumps, spins, and dance moves on ice. Their footwear are figure skates. It was the first winter sport to be included in the Olympic Games, with its introduction occurring at the 1908 Olympics in London. pair skating, and ice dance; the four individual disciplines are also combined into a team event, which was 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

thumb|"Central Park, Winter: the Skating Pond", 1862 lithograph|left|200x200px

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,

The term "figure skating" is an English-language term; the sport is called Eiskunstlauf (lit. "Ice Art Run") in German and patinage artistique (lit. "artistic skating") in French.

Figure skates

The most visible difference from 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. 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

Since 1980, all figure skating competitions must be held in completely covered and enclosed rinks. The rule was expanded to include practice rinks in 1984. According to figure skating historian James R. Hines, the development of indoor ice rinks, other than the development of the bladed skate during the 14th century and the practice of fastening boots permanently to skates in the 19th century, has had the greatest effect on figure skating. It allowed for skating year-round, as well as anywhere in the world, and prevented the cancellation of competitive events due to the lack of ice in outdoor rinks. The first attempts to make artificial ice occurred during the 1870s in England and the U.S. The first notable indoor ice rink was made in 1876, by John Gamgee, in Chelsea along the north bank of the Thames River; it measured 24 by 40 feet. By the end of the 19th century, many major cities in Europe and North America had indoor rinks.

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 . 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.

Disciplines

Figure skating consists of the following disciplines:

  • In single skating, male and female skaters compete individually. Figure skating is the oldest winter sport contested at the Olympics, with men's and women's single skating appearing as two of the four figure skating events at the London Games in 1908. Single skating has required elements that skaters must perform during a competition and that make up a well-balanced skating program. They include jumps (and jump combinations), spins, step sequences, and choreographic sequences.
  • Pair skating is defined as "the skating of two persons in unison who perform their movements in such harmony with each other as to give the impression of genuine Pair Skating as compared with independent Single Skating". The ISU also states that a pairs team consists of "one Woman and one Man". Pair skating, along with men's and women's single skating, has been an Olympic discipline since figure skating, the oldest Winter Olympic sport, was introduced at the 1908 Summer Olympics in London. The ISU World Figure Skating Championships introduced pair skating in 1908. Pair skating required elements include lifts, twist lifts, jumps and partner assisted jumps, pair spins, death spirals, step sequences, and choreographic sequences. The elements performed by pairs teams must be "linked together by connecting steps of a different nature" and by other comparable movements and with a variety of holds and positions.
  • Ice dance historically draws from ballroom dancing. It joined the World Figure Skating Championships in 1952, and became a Winter Olympic Games medal sport in 1976. According to the ISU, an ice dance team consists of one woman and one man.
  • Synchronized skating (formerly known as "precision skating") is for mixed-gender groups of between twelve and twenty figure skaters. This discipline resembles a group form of ice dance, with additional emphasis on precise formations of the group as a whole and complex transitions between formations. The basic formations include wheels, blocks, lines, circles, and intersections. The close formations, and the need for the team to stay in unison, add to the difficulty of the footwork performed by the skaters in these elements. Formal proposals were put forward by the ISU to include synchronized skating in the 2022 Winter Olympics, but those efforts have been unsuccessful. For approximately the first 50 years of figure skating as a sport, until 1947, compulsory figures made up 60 percent of the total score at most competitions around the world. These figures continued to dominate the sport, although they steadily declined in importance, until the ISU voted to discontinue them as a part of competitions in 1990. Since 2015 with the founding of the World Figure Sport Society and the World Figure & Fancy Skating Championships & Festival on black ice, more skaters are training and competing in figures. More coaches are learning the new methods developed by World Figure Sport to teach them to skaters, as some skaters and coaches believe that figures give skaters an advantage in developing alignment, core strength, body control, and discipline.

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). 34 years after the first-ever quadruple jump (a quad toe loop) was landed by Canada's Kurt Browning at the World Figure Skating Championships in 1988.

The takeoff speed of a jump can reach up to 25 kilometers per hour. 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):

  1. Toe loop – the skater takes off backwards from the outside edge of the right (or left) foot, launching the jump using the opposite toe pick.
  2. Flip (sometimes known as a toe salchow)the skater takes off backwards from the inside edge of the left (or right) foot and assists the take-off using the opposite toe pick.
  3. Lutz – similar to the flip, but the skater takes off from the backward outside edge of the left (or right) foot, launching the jump using the opposite toe pick.

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

thumb|upright=1.15|An Axel jump

Edge jumps use no toe assist, and include (in order of score value):

  1. Salchow – the skater takes off backwards from the inside edge of the left (or right) foot, allowing the edge to come round, the opposite leg helps to launch the jump into the air.
  2. Loop (also known as a Rittberger jump)the skater takes off backwards from the outside edge of the right (or left) foot.
  3. Axel – the skater takes off forwards from the outside edge of the left (or right) foot. As this is the only rotating jump to take off from a forward edge, it includes an extra half rotation.

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:

  • Russian split, performed in a position that is similar to that of a straddle split
  • front split, performed in the position of the more traditional split, facing the direction of the front leg

Spins

Spins are an element in which the skater rotates, centered on a single point on the ice, while holding one or more body positions. They are performed by all disciplines of the sport. As The New York Times says, "While jumps look like sport, spins look more like art. While jumps provide the suspense, spins provide the scenery, but there is so much more to the scenery than most viewers have time or means to grasp". According to world champion and figure skating commentator Scott Hamilton, spins are often used "as breathing points or transitions to bigger things" There are five groups of lifts in pair skating, categorized in order of increasing level of difficulty. Twist lifts are "the most thrilling and exciting component in pair skating". They require more strength and coordination than many other pair elements, and are usually the first or second element in a program. According to the International Skating Union (ISU), "the Woman must be caught in the air at the waist by the Man prior to landing and be assisted to a smooth landing on the ice on a backward outside edge on one foot" during a twist lift.

The ISU defines dance lifts as "a movement in which one of the partners is elevated with active and/or passive assistance of the other partner to any permitted height, sustained there and set down on the ice". Dance lifts are delineated from pair lifts to ensure that ice dance and pair skating remain separate disciplines. After the judging system changed from the 6.0 system to the ISU Judging System (IJS), dance lifts became more "athletic, dramatic and exciting". There are two types of dance lifts: short lifts, which should be done in under seven seconds; and combination lifts, which should be done in under 12 seconds.

Turns, steps, 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.

Competition format and scoring

thumb|Pair Skaters [[Riku Miura and Ryuichi Kihara performing a cantilever during their short program at the 2024-25 Grand Prix Final]]

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) (Since 2009). 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.

Overall Medals (Stage 1 + Stage 2)

Medals awarded to the skaters who achieved the highest overall placements in each discipline.

Small Medals

Small Medals awarded only at ISU Championships since probably 2009:

Stage 1 = Small medals awarded to the skaters who achieved the highest short program or rhythm dance placements in each discipline.

Stage 2 = Small medals awarded to the skaters who achieved the highest free skating or free dance placements in each discipline.

Small Medals awarded only at ISU Championships:

  1. World Figure Skating Championships
  2. World Junior Figure Skating Championships
  3. European Figure Skating Championships
  4. Four Continents Figure Skating Championships

Small Medals not awarded in:

  1. Figure skating at the Olympic Games
  2. ISU Grand Prix of Figure Skating
  3. or any other international competitions

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).

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 nine 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.

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, the Challenge Of Champions, and the Canadian Professional Championships.

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: 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. In 2004, the rule was extended to allow women to wear trousers. The move came after the 2022 Winter Olympics scandal over Kamila Valieva's doping allegations and the controversy over her responsibility as a minor.

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 dates disappeared from the website by February 15. Jessica Dubé, 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.

Eating disorders and RED–S

thumb|right|[[Gracie Gold at the 2016 Four Continents Championship.]]

Eating disorders are reportedly common in figure skating Skaters such as Gracie Gold and Ashley Wagner have faced issues such as eating disorders and depression.

Doping

Figure skaters occasionally have positive doping results but it is not common.

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's death. 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, Beginning in 1968, the ISU progressively reduced the weighting of compulsory figures and introduced the short program in 1973.

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. 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.
