Abstract Gymnastics gear for performance of gymnastic exercises, where the gymnastics gear comprises at least a twisting belt, where the twisting belt comprises a first ring, typically an outer ring, and a second ring, typically an inner ring, where the two said rings are concentrically joined and can rotate in regard to each other about a common axis, where the first ring furthermore comprises at least two connection devices, where said connection devices are preferably arranged symmetrically at the outer periphery of the first ring and adapted for joining to a high-tensile or elastic rope, where the second ring also comprises connection devices at the periphery, where these connection devices are adapted for direct or indirect mounting of connection elements to a somersault belt, where the somersault belt is an inflatable somersault belt comprising at least one chamber and at least one valve, which achieves both a good centering of the somersault belt and a good tightening to the body of the gymnast, and where one and the same somersault belt can be adapted to gymnasts of different size as optimally as possible. ## Claims ### Claim 1 Gymnastics gear for performance of gymnastic exercises, where the gymnastics gear comprises at least a twisting belt and a somersault belt, where the twisting belt comprises a first ring as an outer ring, and a second ring as an inner ring, where the two said rings are concentrically joined and rotatable in regard to each other about a common axis, where the first ring furthermore comprises at least two connection devices, where said connection devices are arranged on the outer periphery of the first ring (3) and adapted for joining to a high-tensile or elastic rope, where the second ring also comprises connection devices at the periphery for connecting to complementary connection elements of the somersault belt, wherein the somersault belt is an inflatable somersault belt comprising at least one chamber and at least one valve, and wherein the at least one chamber comprises at least a number of wires placed between an outer side and an inner side of the inflatable somersault belt. ### Claim 2 (depends on 1) Gymnastics gear according to claim 1, wherein the gymnastics gear furthermore comprises a number of the connection elements in the form of straps, where one or more of the straps include a joining device for connecting to a complementary joining device on either the strap itself, on the second ring, or on an inflatable somersault belt. ### Claim 3 (depends on 1) Gymnastics gear according to any claim 1, wherein the second ring comprises a recess along the periphery, where the recess comprises an opening, where the opening is adapted to receive one or more connection elements, where said opening has a size which is narrower than the recess itself. ### Claim 4 (depends on 1) Gymnastics gear according to claim 1, wherein the connection elements comprise a joining device, where the joining device comprises mechanical coupling elements. ### Claim 5 (depends on 1) Gymnastics gear according to claim 1, wherein the first ring is of fiber composite. ### Claim 6 (depends on 1) Gymnastics gear according to claim 1, wherein there is arranged between the first ring and the second ring a number of bearing balls and/or bearing rollers, where said bearing balls and bearing rollers are made of steel, ceramics, or some other suitable shape-stable and friction-resistant material. ### Claim 7 (depends on 1) Inflatable somersault belt for use in the gymnastics gear according to claim 1, wherein the inflatable somersault belt comprises at least one chamber and at least one valve and a number of connection elements to connect the inflatable somersault belt to the twisting belt, and wherein the at least one chamber comprises at least a number of wires placed between the outer side and the inner side of the inflatable somersault belt. ### Claim 8 (depends on 1) Method for use of a gymnastics gear according to claim 1, where the method involves at least the following steps: at least the inflatable somersault belt is placed around the body of a gymnast, a gas species is pumped via a valve into the at least one chamber of the inflatable somersault belt. ### Claim 9 (depends on 8) Method for use of a gymnastics gear according to claim 8, wherein the gas species is air. ### Claim 10 (depends on 2) Gymnastics gear according to claim 2, wherein the joining device is selected from the group consisting of hook-and-loop fasteners (VELCRO™), buckles, couplings or combinations thereof. ### Claim 11 (depends on 1) Gymnastics gear according to claim 1, wherein the gymnastics gear furthermore comprises a number of the connection elements in the form of four or more straps, where one or more of the straps include a joining device for connecting to a complementary joining device on either the strap itself, on the second ring, or on an inflatable somersault belt. ### Claim 12 (depends on 11) Gymnastics gear according to claim 11, wherein all the four or more straps comprise the joining device. ### Claim 13 (depends on 11) Gymnastics gear according to claim 11, wherein the joining device is selected from the group consisting of hook-and-loop fasteners (VELCRO™), buckles, couplings or combinations thereof. ### Claim 14 (depends on 5) Gymnastics gear according to claim 5, wherein the fiber composite includes fibers selected from the group consisting of glass fibers, carbon fibers, vegetable fibers or combinations thereof. ### Claim 15 (depends on 1) Gymnastics gear according to claim 1, wherein the second ring is of fiber composite. ### Claim 16 (depends on 15) Gymnastics gear according to claim 15, wherein the fiber composite includes fibers selected from the group consisting of glass fibers, carbon fibers, vegetable fibers or combinations thereof.
