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.
