Editing Floor (gymnastics) (section)

== The apparatus ==
The apparatus originated as a 'free exercise' for men, very similar to the floor exercise of today.<ref>{{Cite web|title=FIG - Discipline|url=https://www.gymnastics.sport/site/pages/disciplines/hist-mag.php|access-date=2021-04-28|website=www.gymnastics.sport}}</ref> Most competitive gymnastics floors are spring floors. They contain [[Spring (device)|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.<ref>{{Cite web|title=The American Gym|url=https://www.theamericangym.com/floorinfo.asp|access-date=2021-04-28|website=www.theamericangym.com}}</ref><ref>{{Cite web|title=Interactions of the Gymnast and Spring Floor|url=https://www.xcitex.com/articles/interactions-gymnast-spring-floor-article.pdf|access-date=2021-04-28|archive-date=2022-12-01|archive-url=https://web.archive.org/web/20221201230040/http://xcitex.com/articles/interactions-gymnast-spring-floor-article.pdf|url-status=dead}}</ref> Floors have designated perimeters called the delimitation strip, indicating an out of bounds area.<ref name=":0">{{Cite web|title=Apparatus Norms|url=https://www.gymnastics.sport/publicdir/rules/files/en_Apparatus%20Norms.pdf|publisher=[[Fédération Internationale de Gymnastique|FIG]]|pages=30,68,84,118}}</ref>
