Artistic roller skating is a sport which consists of a number of events. These are usually accomplished on quad skates, but inline skates may be used for some events. Various flights of events are organized by age and ability/experience. In the US, local competitions lead to 9 regional competitions which led to the National Championships and World Championships. skaters trace figure circles painted on the surface of the floor. This is different to compulsory figures on ice, who skate on blank ice and draw their own circles, leaving tracings on the ice as they skate. The official dimension of plain figure circles, measured at their diameter is 6 meters (19 feet, 81⁄4 inches). The official dimension of smaller loop figure circles measure at 2.4 meters (7 feet, 101⁄2 inches). Circles are typically painted in "serpentines"—sets of three circular lobes.
The basic figures skated are typically referred to by numbers, the same as those skated by ice skaters, ranging from simple circle eights through serpentines (figures using one push for a circle and a half), paragraphs (figures using one push for two circles), and loops (smaller circles with a teardrop-shaped loop skated at the top of the circle). There is one category of simple figures (111 and 112) that are unique to roller skaters; these are serpentines that begin with a half circle skated on one foot, then change to the other foot, for the next circle, then change back to the other foot for another half circle. Some of the more basic figures are numbered 1, 2, 1B, 5A, 5B, 7A, 7B, 111A, 111B, 112A, and 112B, in which the letter B designates starting on the left foot. These figures are often taught as beginning figures for those just starting. They include simple circle eights, circle eights with three turns, and serpentines. More difficult figures include the use of turns like counters, brackets, and rockers, and they are numbered 19, 21, 22, 26, etc.
Judges in figure events consider the quality of the skater's tracing of the circle, clean takeoffs, edges and correct placement of turns. The skater's form and posture is emphasized as well.
Dance roller skating contains three major sub-disciplines: Compulsory dance, original dance, and free dance.Compulsory dance contains prescribed compulsory dances and steps that must be performed, such as the Imperial Tango, the 14 Step, the Keats Foxtrot , or the Flirtation Waltz. Some of the dances are the same as performed in ice dancing competition, while others are unique to roller skating.
American Dance is performed only at the United States National level and below, and emphasizes keeping the upper body upright and free from movement. Some examples of American dances are the Fascination Foxtrot, Progressive Tango, and the California Swing. Original Dance consists of a dance constructed of two rhythms chosen from a set of rhythms that FIRS changes every year . In 2008 the set rhythms were "Spanish Melody" ( Paso Doble, Flamenco, Tango, and Spanish Waltz ).
Free Dance is similar to the ice free dance, although with some rules changes. Skaters do not need to follow a pattern around the floor, but rather must be creative in their interpretation of the music. Dancers cannot do any jumps or spins that are recognizable in freestyle skating.Another style similar to free dance is called Creative Solo Dance, or CSD. This has a tighter pattern than a free dance, but is created by the skater or their coach. This pattern can be to any music, as long as it does not change speed. The pattern must be repeated twice, with opening and closing steps.
Solo Dance incorporates all three sub-disciplines. Compulsory dances generally utilise the female steps as these are usually more difficult than the male steps. Original dance is referred to as Creative Solo Dance or CSD, and free dance incorporates up to two spins with no more than 3 revolutions and up to two jumps of no more than 1 revolution.
Roller skating also traditionally emphasizes spins that are uncommon on ice, especially the inverted camel in which the skater is on an outside edge with their body and left leg extended outward parallel to the floor, the skater then rotates their hips 180 degrees while continuing to spin so that they are spinning upside down  The inverted camel is generally performed by women; few men learn to do it and even fewer perform it in competition. Other spins popular in roller skating that would be impossible to do with the blades of an ice skate include the broken ankle, which begins as an inside-edge camel and the skater then pushes the skate over so that the spin is rotating on the edge of the two inner wheels, and the heel camel spin, which is only rotated on the back two wheels, or heel.
Precision roller skating consists of 12–24 athletes skating on the floor at one time moving as one flowing unit at high speeds. This discipline of Precision skating is named because of the emphasis on maintaining precise formations and timing of the group.
For a precision team to flow in unison, individual skaters must be competent at a variety of skating skills, including speed, footwork and presentation. The team performs a program set to music, with required formations including circles, lines, blocks, wheels, and intersections. The teams are required to perform difficult step sequences involving a number of complicated turns.
There are international synchronized skating competitions at the Senior level, and the Federation Internationale de Roller Sports (FIRS) held the first World Championship in Precision Roller Skating in 2000. Teams may consist of men and women with Senior Teams having 12–24 team members and Junior Teams having 8-16 team members. Two scores are given, one for technical and one for artistic impression.
Precision Roller Skating owes its origin to Synchronized skating on ice. The first synchronized figure skating team was formed by Dr. Richard Porter, who became known as the 'father of synchronized skating'. The 'Hockettes' skated out of Ann Arbor, Michigan and entertained spectators during the intermissions of the University of Michigan Wolverines men's ice hockey team. In the early days, precision skating resembled a drill team routine, or a precision dance company such as The Rockettes.
During the 1970s, the interest for this new sport spawned tremendous growth and development. In each season, teams developed more creative and innovative routines incorporating stronger basic skating skills, new maneuvers and more sophisticated transitions with greater speed, style and agility. Due to the interest in the sport in North America, other countries took notice, leading to the World Championships. With the internationalization of the sport, it has evolved rapidly, with increasing emphasis on speed and skating skills.
Although not currently an Olympic sport, fans and participants of this fast-growing discipline have begun to strive for recognition by the rest of the athletic world. Precision Roller Skating has been covered by Roller Skating and the USARS magazine since the sport's inception. It is a varsity sport at a few colleges, and both Precision Roller Skating and its ice counterpart are being reviewed for Olympic eligibility.
Creative Solo/Free Dance
Artistic roller skaters who participate in this event most likely do solo dance or team dance. This event requires the coach and skater to select a song that can stay appropriate for any age. For example, songs from Mary Poppins, Singin' In The Rain etc. It is up to the coach or choreographer to design a routine that has a maximum of three jumps and two spins and has some dance moves such as swings, runs, etc.. As of the 2016–2017 season, USARS has decided to add tumbling to their total score, allowing skaters to do optional cartwheels, splits and other forms of tumbling.
This event is taken to the World Championships, however, only for Junior World Class and World Class Skaters only, these skaters are asked to compete in an international-style creative which can be French theme, African Theme, European Theme and the most popular: Spanish Themed. As of the 2015–2016 skating season, USARS opened up an Elementary International Creative Solo/Free dance event which allows 12 year olds and under to participate in an international-style routine that would be taken to regional and national championships. This event can be a combined, combining with international solo dance scores as a potential spot to go to nationals.
To skate the combined event at regionals/nationals, skater must pay a separate entry fee to have the scores for International free dance and International Solo Dance combined for a chance to get an extra medal and extra ticket to nationals.
The style dance is an event only participants can compete in for Junior and Senior World Class (the skaters trying to make it on the world team for their country). The style dance is international, which means it must have an international flare. Music can be in any language, and costume has to match the music theme.
The style dance does not need to have jumps or spins but does require repetitions of the given dance. This event is dance but does require a toe stop as there is footwork that needs to be included.
