A fluid current producing apparatus assembly for use in a body of water includes at least one receptacle 2, current producing apparatus 3 and inflation and deflation apparatus 22c. Each receptacle 2 includes a body forming at least one enclosed inside space which further contains at least one independently inflatable and deflatable compartment 19 therein for receipt of a fluid to at least inflate at least a portion of the receptacle. Each receptacle includes a body having an inner surface 17b, outer surface 17a and at least one internal chamber 19 which is inflated by the inflation and deflation apparatus 22c which modifies the outward shape of receptacle 2. When the fluid is forced by current producing apparatus 3 over the outer 17a of each receptacle 2 or chamber from a front of the current producing apparatus 3 or away from the current producing apparatus 3, and fluid is drawn in predominantly from around the current producing apparatus 3 and the sides of the at least one receptacle 2 back to the current producing apparatus 3 in a circuit of flow, thereby creating different current or wave patterns for the water flowing over the outer surfaces 17a of, inflatable, chamber portions 30, 31. A method is also included.

An aquatic training aid includes a paddle member for wearing by a swimmer, a variable diaphragm disposed within the paddle member, the variable diaphragm including a plurality of fitted blades arranged to form an aperture, and a housing peripherally framing the plurality of fitted blades. The variable diaphragm is adjustable to change the aperture from a first expanded position to a second contracted position, and hydrodynamic characteristics of the aquatic training aid when moved through water are affected by the change of the aperture. Controlling the aperture enables the swimmer to adjust the resistance provided by the aquatic training aid when it is moved through water.

A swimming board having a buoyant board body having an upper surface defining, with a continuous body sidewall, a channel recessed into the board body and disposed proximal to the second end of the board body and having a strap fastening assembly coupled to the board body and with a groin strap and a waist strap that define apertures for receiving a user's legs and retaining the user to the board body.

A folding inflation-free breaststroke float comprises a U-shaped main body and a supporting pad arranged in the main body. The supporting pad is arranged around an inner ring of the main body; the main body is also provided with back sheets, shoulder straps, buckles and a crotch; the main body is combined by at least two connecting parts; the joined connecting parts can be turned or disassembled and then overlapped; and a detachable connecting piece is arranged between the joined connecting parts. Compared with the prior art, by turning a first connecting part and second connecting parts, the first connecting part and the second connecting parts are overlapped, thereby reducing the overall volume during transportation and reducing transportation cost.

The present invention relates to a chest float, comprising a float body; and a support pad, wherein both sides thereof are in detachable connection with both sides of the inner edge of the float body; first and second back limit pads are respectively extended from the two sides of the support pad, the first and second back limit pads are in detachable connection, and a wrapping space is enclosed by the support pad, and first and second back limit pads; when support pad is demounted from the inner edge of the float body from the two sides, the use state of the chest float is switched to the use state of a waist float. By means of the detachable design of the support pad, the chest float realizes the switching between the lying prone state and standing state of an infant, and is adapted to infants of different ages.
