FIELD: medicine, sport. ^ SUBSTANCE: invention refers to a gymnastic apparatus (1) for water gymnastics comprising a resting base (3) held by a foot or a hand, and a dome (5) rigidly connected to the resting base (3) and deformable under water pressure exerted when gymnastic apparatus (1) moves. The dome is formed by a flexible skirt (7) and rigid blades (9), and the collar skirt has an internal peripheral edge (11) and an external peripheral edge (13). The internal peripheral edge (11) is rigidly connected to the external peripheral edge (15) located on the resting base (3). The blades (9) are radially distributed around the skirt, and the internal edges (17) of the blades (9) are distanced from the internal peripheral edge (11) of the skirt. The resting base (3) comprises resting means (19) distributed along its external peripheral edge (15) and mounted to support on an upper side (21) of the blades (9). The invention also refers to a kit for water gymnastics equipped with a shoe type support and a gymnastic apparatus (1). ^ EFFECT: limited turbulent flows ensured by an improved hydrodynamic shape. ^ 17 cl, 8 dwg |
