Figure skating



Figure skating is a sport in which individuals, duos, or groups perform on figure skates on ice. It was the first winter sport to be included in the Olympic Games, when it was contested at the 1908 Olympics in London. The four Olympic disciplines are men's singles, ladies' singles, pair skating, and ice dance. Non-Olympic disciplines include synchronized skating, Theater on Ice, and four skating. From intermediate through senior-level competition, skaters generally perform two programs (short and free skate), which may include spins, jumps, moves in the field, lifts, throw jumps, death spirals, and other elements or moves, depending on the discipline.

The blade has a groove on the bottom creating two distinct edges: inside and outside. Judges prefer that skaters glide on one edge of the blade and not on both at the same time, which is referred to as a flat edge. During a spin, skaters use the "sweet spot" of the blade, formally called a rocker, which is the roundest portion of the blade, just behind the toe pick and near the middle of the blade. Skates used in singles and pair skating have a set of large, jagged teeth called toe picks on the front of the blade. Toe picks are mainly used for the take-off on jumps. Ice dance blades have smaller toe picks.

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 include former Olympic and World champions who have ended their competitive career as well as skaters with little or no international competitive experience.

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 in relation 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 3/16 inch (4.7 mm) 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 180–220 cm. 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.

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 in order to practice sufficient rotation and height of their jumps, and to practice consistency in landing on one foot.

Ice rinks and rink equipment
There is significant variation in the dimensions of ice rinks. Olympic-sized rinks have dimensions of 30 x, NHL-sized rinks are 26 x, while European rinks are sometimes 30 x. 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 -5.5 C and -3.5 C, 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.

Olympic disciplines
As an Olympic sport, figure skating comprises the following disciplines:


 * Singles competition for men and women (referred to as "ladies" in ISU rulebooks), wherein individual skaters perform jumps, spins, step sequences, spirals, and other elements in their programs.
 * Pair skating teams, consisting of a man and a woman skating together. Pairs perform elements that are specific to the discipline such as: throw jumps, in which the man 'throws' the woman into a jump; lifts, in which the woman is held above the man's head in one of various grips and positions; pair spins, in which both skaters spin together about a common axis; death spirals; and other elements such as side-by-side jumps and spins in unison.
 * Ice dance is again for couples consisting of a woman and a man skating together. In contrast to pair skating, ice dance focuses on intricate footwork performed in close dance holds, in time with the music. Ice dance lifts must not go above the shoulder, and throws and jumps are disallowed.

The four disciplines of men's singles, ladies' singles, pair skating and ice dance are also incorporated into a team event, which appeared on the Olympic program for the first time at the 2014 Winter Olympics.

Other disciplines

 * 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 have been put forward by the ISU to include synchronized skating in the 2018 and 2022 Winter Olympics, but so far these efforts have been unsuccessful.
 * Ice theatre, also known as "Theatre on Ice" (or "Ballet on Ice" in Europe), is a form of group skating that is less structured than synchronized skating and allows the use of theatrical costuming and props.
 * Four skating is a discipline in which a team of four skaters, consisting of two men and two women, perform singles and pairs elements in unison, as well as unique elements that involve all four skaters.
 * Special figures is the tracing of elaborate original designs on the ice. This was a common discipline in the early days of figure skating (hence the name of the sport) and appeared once at the Olympics, in 1908.
 * Adagio skating is a form of pair skating most commonly seen in ice shows, where the skaters perform many acrobatic lifts, but few or none of the other elements that are performed by competitive pair skaters.
 * Acrobatic skating, also known as "Acrobatics on ice" or "Extreme skating", is a combination of circus arts, technical artistic gymnastics skills, and figure skating.

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.

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 ¼, but less than ½ revolution" and receives 70% of the base value. A downgraded jump (indicated by <<) is "missing rotation of ½ 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 in 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 which 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. The two categories of jumps are 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 begins with 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. Triple jumps other than the axel are commonly performed by female single skaters. It is extremely rare for a female skater to land a quadruple jump; the only two female single skaters to be credited with quads in competition are Miki Ando, who landed the first quad salchow in Dec 2002, and Alexandra Trusova, who landed the first quad toe loop (and only the second quad salchow) in March 2018, both at the Junior level. Alexandra Trusova also was the first female to ever land 2 quadruple jumps in competition, the quad salchow and the quad toe loop. She was only 13 years old at the time.

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.

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
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
There are also a number of other jumps that 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, 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
 * ladies split, performed in the position of the more traditional split, facing the direction of the front leg

Spins
Spins are a required element in all four Olympic disciplines. There are three basic positions – upright, sit and camel – with numerous variations.


 * Upright spin variations include layback, Biellmann, haircutter, layover layback, attitude, and pearl.
 * Sit spin variations include pancake, broken leg, tuck behind, cannonball, flying, and clam.
 * Camel spin variations include catch-foot, layover, flying, and donut.

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 counter-clockwise. Most skaters favor a counter-clockwise direction of rotation when spinning (as in jumping), but there are some skaters who prefer to spin in the clockwise direction. A small minority of skaters are able to 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 back spin. The opposite applies for 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 back spin.

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 in 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:
 * Armpit holds are not generally used in elite senior competition.
 * Waist holds
 * Hand-to-hip holds
 * Hand-to-hand lifts are divided into two types:
 * Press lifts
 * Lasso lifts, in order of increasing difficulty:
 * Toe or step in lasso
 * Axel or backward lasso
 * Reverse lasso

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.
 * Stationary lift – A lift performed "on the spot". The lifting partner does not move across the ice, but is allowed to rotate.
 * Straight line lift – The lifting partner moves in a straight line across the ice. This lift may be performed on one foot or two.
 * Curve lift – The lifting partner moves along a curve across the ice. This lift may be performed on one foot or two.
 * Rotational lift – The lifting partner rotates in one direction while traveling across the ice.

Long lifts may last up to ten seconds in competition on the senior level.
 * Reverse rotational lift – The lifting partner rotates in one direction, then switches and rotates in the other direction, while traveling across the ice.
 * Serpentine lift – The lifting partner moves in a serpentine pattern across the ice.
 * Combination lift – A lift combining two of the four short lifts. Each part of the lift must be fully established.

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:

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, prior to 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.
 * 1) Skating skills (SS) reward use of edges and turns, flow over the ice surface, speed and acceleration, ice coverage, clean and controlled curves, multi-directional skating, and mastery of one-foot skating (no overuse of skating on two feet).
 * 2) Transitions (TR)
 * 3) Performance (PE)
 * 4) Composition (CO)
 * 5) Interpretation (IN)

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
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.
 * ISU Championships (World, European, Four Continents, and World Junior Championships) and Olympic Winter Games: The best result by points per season, the best two results by points over the three seasons.
 * ISU Grand Prix of Figure Skating and Final (senior and junior): The two best results by points per season, the best four results by points over the three seasons.
 * International senior calendar competitions: The two best results by points per season, the best four results by points over the three seasons.

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 prior to 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
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 costumemaker.

According to current ISU regulations, costumes in competition "must be modest, dignified and appropriate for athletic competition – not garish or theatrical in design. Clothing may, however, reflect the character of the 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.

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. Prior to 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 in order 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 switching to 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 ladies' 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 ladies' 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 in order to be allowed to perform in a show.

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 there are many skaters 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. In addition, 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.

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 (artilleryman) (c1740-c1788) of Royal Arsenal, is the first known book on figure skating. He designed skates that could be attached to the shoes (by screws through the heels) rather than by straps, and these were soon available from Riccard's Manufactory in London. Competitions were then held in the "English style" of skating, which was stiff and formal and bore very little resemblance to modern figure skating. Before the changes in figure skating techniques, there were a limited number of moves that could be performed. This was true in the mid-1800s but was later changed by American skater Jackson Haines, who was considered to be the "father of modern figure skating". He introduced a new style of skating in the mid-1860s, incorporating free and expressive techniques, which became known as the "international style." Although popular in Europe, Haines' international style of skating was not widely adopted in the United States until long after his death.

Early 1900s


The ISU was founded in 1892. The first European Championships were held in 1891, and the first World Championships were held in 1896 and won by Gilbert Fuchs. Only men competed in these events. In 1902, a woman, Madge Syers, entered the World competition for the first time, finishing second. The ISU quickly banned women from competing against men, but established a separate competition for "ladies" in 1906. Pair skating was introduced at the 1908 World Championships, where the title was won by Anna Hübler and Heinrich Burger. Figure skating was the first winter sport introduced to the Olympics; its Olympic debut came at the 1908 Summer Olympics.

On March 20, 1914 an international figure skating championship was held in New Haven, Connecticut. This was the ancestor 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, who turned competitive success into a lucrative professional career as a movie star and touring skater. Henie also set the fashion for female skaters to wear short skirts and white boots. The top male skaters of this period included Gillis Grafström and 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, which meant that skaters who could build up a big lead in figures could win competitions even if they were mediocre free skaters. As television coverage of skating events became more important, so did free skating as this was televised and seen by general public and the compulsory figure competition was not. The television audience would complain when great free programs did not always equate to gold medal victories. Beginning in 1968, the ISU began to progressively reduce the weight of figures and introduced the short program in 1973. A critical issue was said to have been the continued failure of the Janet Lynn at the world stage in spite of her fantastic free skate programs. For example, she did not get onto the podium at the 1971 World Championships after winning the free skate competition decisively resulting in an uproar and loud booing among the audience during the medal ceremony.

With these changes, the emphasis in competitive figure skating shifted to increasing 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. Although it was expected that quads would soon become an important part of men's skating, it was a number of years before this happened. Japan's Midori Ito landed the first triple axel by a woman in 1988 pushing the athletic and technical level for women's programs. Worth only 20% by 1989, figures were eliminated entirely from international competition in 1990.

Television showing skaters in the kiss and cry area after competing contributed to the sport's popularity. 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 who were intending to skate professionally to return to ISU competition if they obtained their national association's permission. To retain skaters who might otherwise have given up their eligibility to participate in lucrative professional events, in 1995 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, ladies' 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, out of over 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 ladies' figure skating competition in the 1994 Winter Olympics achieved higher TV Nielsen ratings than that year's Super Bowl and was the most watched sports television program of all time, to that date.

Spectators sometimes throw a variety of items, most commonly stuffed toys and flowers, onto the ice in support of their favorite skaters but officials discourage flowers which are not fully wrapped due to the possibility of debris disrupting or endangering the following skaters.

Countries who have produced many successful skaters in recent decades 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.

Four skating has mostly disappeared while synchronized skating, singles/pair skating and ice dance have grown. On April 6, 2011, the IOC officially confirmed the approval of a team event, which was introduced at the 2014 Winter Olympics. The elimination of the compulsory dance provided space for the team event. Each team is composed of a men's and ladies' singles skater, a pair, and an ice dance duo. Ten teams may compete, with five eliminated after the short program. In December 2011, the ISU released details of the qualifying system and the competition.

In popular culture
In 1937, Sonja Henie appeared in the film Thin Ice. Figure skating has been the focus of several later Hollywood films, including The Cutting Edge (and its sequels, The Cutting Edge: Going for the Gold, The Cutting Edge: Chasing the Dream and The Cutting Edge: Fire and Ice), Ice Princess, Ice Castles, Ice Angel, Go Figure, Blades of Glory, and I, Tonya. Olympic champion Brian Boitano was parodied in South Park: Bigger, Longer & Uncut in the song "What Would Brian Boitano Do?".

In 2006, Dancing on Ice began broadcasting in the UK. The show involves celebrities and their professional partners figure skating in front of a panel of judges. The judges have included British Olympic gold medalists Torvill and Dean and double Olympic champion Katarina Witt. The show has since been exported to other countries around the world.

U.S. national champion Johnny Weir was the focus of the reality show Be Good Johnny Weir which aired on the Sundance Channel. Figure skating plays a prominent role in Yuri on Ice, an anime that aired in autumn 2016 which focuses on the career of fictional figure skater Katsuki Yuri.
