Acrosport is an acrobatic sport that involves building human pyramids and performing gymnastic elements in groups while set to music. It originated from ancient performances but was further developed in 18th century circuses. Acrosport is now governed by the International Federation of Sports Acrobatic and competitions are held in categories of twos, threes, and fours. Key roles in Acrosport include the top, who must be flexible and balanced at the peak of pyramids, the base, who provides stability, and helpers who aid in construction and provide security.
