A skipping rope (British English) or jump rope (American English) is a tool used in the sport of skipping/jump rope where one or more participants jump over a rope swung so that it passes under their feet and over their heads. There are multiple subsets of skipping/jump rope, including single freestyle, single speed, pairs, three-person speed (Double Dutch), and three-person freestyle (Double Dutch freestyle). There are a few major organizations that support jump rope as a sport. Often separated by sex and age, events include hundreds of competitive teams all around the world. In the US, schools rarely have jump rope teams, and states do not sanction official events for high school or elementary school. In freestyle events, jumpers use a variety of basic and advanced techniques in a routine of one minute, which is judged by a head judge, content judges, and performance judges. In speed events, a jumper alternates their feet with the rope going around the jumper every time one of their feet hit the ground for 30 seconds, one minute, or three minutes. The jumper is judged on the number of times the right foot touches the ground in those times.
