Floor (gymnastics)

Floor (gymnastics)
In gymnastics, the floor is a specially prepared exercise surface, which is considered an apparatus. It is used by both male and female gymnasts. The gymnastics event performed on the floor is called floor exercise. The English abbreviation for the event in gymnastics scoring is FX.
A spring floor is used in all of gymnastics to provide more bounce, and also help prevent potential injuries to lower extremity joints of gymnasts due to the nature of the apparatus, which includes the repeated pounding required to train it. Cheerleading also uses spring floors for practice. The sprung floor used for indoor athletics, however, is designed to reduce bounce.
The apparatus
The apparatus originated as a 'free exercise' for men, very similar to the floor exercise of today. Most competitive gymnastics floors are spring floors. They contain springs and/or a rubber foam and plywood combination which make the floor bouncy, soften the impact of landings, and enable the gymnast to gain height when tumbling. Floors have clearly designated perimeters called the delimitation strip, indicating an out of bounds area.
Dimensions
Measurements of the apparatus are published by the Fédération Internationale de Gymnastique (FIG) in the Apparatus Norms brochure. The dimensions are the same for male and female competitors.
Artistic Gymnastics, Acrobatic Gymnastics
Performance area: 1,200 centimetres (39 ft) x 1,200 centimetres (39 ft) ± 3 centimetres (1.2 in)

WAG scoring and rules
Floor exercise routines last up to 90 seconds, and there is one time keeper for this event. The routine is choreographed in advance, and is composed of acrobatic and dance elements. This event, above all others, allows the gymnast to express their personality through her dance and musical style. The moves that are choreographed in the routine must be precise, in sync with the music and entertaining.
At the international elite level of competition, the composition of the routine is decided by the gymnast and their coaches. Many gymnasiums and national federations hire special choreographers to design routines for their gymnasts. Well-known gymnastics choreographers include Adriana Pop (Romania, France, China), Dominic Zito (United States), and Geza Pozar (Romania, United States). Others opt to choreograph their FX routines in-house. Some gymnasts adopt a new FX every year; others keep the same routine for several competitive seasons. It is not uncommon for coaches to modify a routine's composition between meets, especially if it is used for an extended length of time. It is uncommon for gymnasts to use more than one different FX routine in the same season. However, it is not entirely unheard of; for instance, at the 1996 Summer Olympics in Atlanta, Russian Dina Kotchetkova's routine in the FX event finals had completely different music, choreography and composition than that of her all-around exercise.
The music used for the routine is also the choice of the gymnast and their coaches. It may be of any known musical style and played with any instrument(s), but it may not include spoken words or sung lyrics of any kind. Vocalization is allowed if the voice is purely done as an instrument. It is usually the responsibility of the coach to bring the music to every competition.
Scores are based on difficulty, artistry, demonstration of required elements, and overall performance quality. The score is broken up into two pieces, D-score and E-score, which are added together to get the overall score. D-score is a bonus added on to the overall score for the difficulty level of the routine. The D-score is calculated by adding up values for the 8 most difficult skills, connections, and compositional requirements with the following values.
The E-score is based on execution, and begins at a value up to 10.0; deductions are taken for poor form and execution, lack of required elements, and falls. The gymnast is expected to use the entire floor area for her routine, and to tumble from one corner of the mat to the other. Steps outside the designated perimeters of the floor incur deductions. The gymnast will also incur a deduction if there are lyrics in the music.
International level routines
For detailed information on score tabulation, please see the Code of Points article
Routines can include up to four tumbling lines, and several dance elements, turns and leaps. A floor routine must consist of at least:
Connection of two dance elements (one must be a 180 degree split)
Saltos forward/sideways and backward
Double saltos
Saltos with a minimum of one full twist
MAG scoring and rules
Men's floor exercise routines are no longer than 70 seconds, and there is one time keeper for this event. A loud beep will be sounded to alert gymnasts when they have 10 seconds left within the allocated time to finish their routine before receiving a penalty for exceeding the legal time allowed. Routines are typically made up of acrobatic elements, combined with other elements that display the strength and flexibility of the gymnast while using the entirety of the floor area.
As with Women's Artistic Gymnastics, scores are based on difficulty, form and overall performance quality, with the overall score being the addition of the D-score and the E-score. Deductions are taken for lack of flexibility, not using the whole floor area, and pausing before tumbling lines.
International level routines
A floor routine should contain at least one element from all element groups:
I. Non-acrobatic elements
II. Acrobatic elements forward
III. Acrobatic elements backwards, & Arabian elements
The dismount can come from any element group other than group I. Those competing as seniors are required to include a double salto in their routines.
Floor exercises in rhythmic gymnastics
Floor exercises is a category also in the rhythmic gymnastics, but it considers only the youngest gymnasts, up to 10 years old, who perform their routines freehand, which means without any apparatus (in contrary to the remaining five - rope, hoop, ball, clubs and ribbon). Their length and content is still clearly specified and differs in each age category.
