Classes Disciplines Acrobatic Gymnastics Entry into Acrobatic Gymnastic Squad is by invitation only Acrobatic Gymnastics – (previously called Sport Acrobatics and nicknamed "Acro") Practiced by both men and women, Acrobatic Gymnastics is among the oldest known sports known to have been practiced. It is a modern, artistic discipline, which requires courage and trust among gymnasts. Routines are choreographed to music and presented on a 12 X 12 meter sprung floor surface, are full of expression and provides gymnasts with a stage on which to shine. In official competitions, Acrobatic Gymnastics offers five different possibilities of partnerships: Men’s, Women’s and Mixed Pairs, Women’s Group (3 gymnasts), Men’s Groups (4 gymnasts) At SALTO, the Acrobatic Squads are broken up into three squads – Squad, Foundation and Development. These partnerships are constructed in accordance with the gymnasts’ physical and psychological qualities: The Top needs to be aerial, of small body feature, highly flexible and nimble, while the Bases need to be strong, of larger body frame, steady and powerful. A mixed pair must always combine a male Base with a female Top. Gymnasts work in harmony and trust, each responsible for their partner or partners. It is a true and testing examination of human relationships. Routines impose on gymnasts a need for strength, agility, flexibility, balance and acrobatic skills. The results are spectacular, intricate balances performed on partners, exciting multiple somersaults and twisting somersaults with partners being pitched and caught. The routines presented in competitions are up to 2 minutes and 30 seconds in length and must include a number of required collective (partnership) and individual elements of three different types: static (balance), dynamic, and combined. While the static routine must present balanced pyramidal constructions held for 3 seconds and other elements of strength, flexibility and agility, the dynamic routine should show flight elements such as throws, pitches and catches as well as dynamic tumbling elements. The combined routine presents elements from both the dynamic and the static routines. Great Britain is one of the most respected nations of the world in Acrobatic Gymnastics and has achieved success at World and European level with medals in all categories.
