Young Brunette Girl Doing Gymnastic Exercises

In the past the Floor Exercise event was executed on wrestling mats. Today, the floor event occurs on a carpeted 12m × 12m square, usually consisting of hard foam over a layer of plywood, which is supported by springs or foam blocks generally called a "spring" floor. This provides a firm surface that provides extra bounce or spring when compressed, allowing gymnasts to achieve extra height and a softer landing than would be possible on a standard floor. Gymnasts perform a choreographed routine up to 90 seconds in the Floor Exercise event They must choose an accompanying music piece. In some gymnastic associations such as United States Association of Gymnastic Clubs (USAIGC), gymnasts are allowed to have vocals in their music but USA Gymnastics competitions a large deduction is taken from the score for having vocals in the music. The routine should consist of tumbling lines, series of jumps, dance elements, acrobatic skills, and turns, or piviots, on one foot. A gymnast can perform up to four tumbling lines that include at least one flight element without hand support. Each level of gymnastics requires the athlete to perform a different number of tumbling passes, in level 7 you are required to do 2–3 and in levels 8–10 at least 3–4 tumbling passes are required.
A gymnast's score comes from deductions taken from their start value. The start value of a routine is calculated based on the difficulty of the elements the gymnast attempts and whether or not the gymnast meets composition requirements. The composition requirements are different for each apparatus. This score is called the D score. Deductions in execution and artistry are taken from 10.0. This score is called the E score. The final score is calculated by taking deductions from the E score, and adding the result to the D score.
