This discipline is open only to women and became an Olympic sport in 1984. It is graceful and elegant. Gymnasts compete on a square mat and using rope, a hoop, a ball, clubs, and a ribbon (in separate events), they perform choreographed movements set to music. Some acrobatic movements are permitted, but no flight is allowed. Each gymnast has to present a composition lasting about 2 minutes 30 seconds. To date the discipline is dominated by young girls from eastern European countries.
