This utility model provides a wearable breaststroke leg posture corrector, belonging to the field of breaststroke leg posture correction technology. It includes: a support base, a lumbar support mounted on the surface of the support base, posterior webs movably connected to both sides of the lumbar support, connecting members movably connected to both sides of the support base, a first connecting plate rotatably connected to the surface of the connecting member, a second connecting plate rotatably connected to the surface of the first connecting plate, and a footrest rotatably connected to the bottom of the second connecting plate. This design, through the setting of multiple straps, facilitates the wearing of the posture corrector and is suitable for users of different body types. After wearing, the coordinated use of the connecting members, the first connecting plate, the second connecting plate, and the footrest can correct the user's leg posture. Furthermore, the lumbar webs can limit or provide feedback on the range of waist rotation, helping swimmers establish a correct hip and shoulder rotation linkage mechanism.

The application relates to a design method of a swimsuit joint line drag reduction, an electronic device and a storage medium, and belongs to the field of competitive swimsuit design and research. The method comprises the following steps: based on swimming postures and corresponding dynamic drag analysis, the characteristic postures of the swimming postures are obtained; wherein the swimming postures include freestyle, backstroke, butterfly stroke and breaststroke; a human body model of the characteristic postures is obtained through human body scanning; computational fluid dynamics simulation is performed on the human body model to obtain a surface streamline diagram; a joint line design area and a design direction of a swimsuit are obtained according to the surface streamline diagram; and the joint line design of the swimsuit is performed according to the swimsuit pattern design and the joint line design area and the design direction. According to the method, the joint line design area and the design direction of the swimsuit are obtained according to the surface streamline diagram, the joint line design of the swimsuit is performed according to the swimsuit pattern design and the joint line design area and the design direction, the increase in drag caused by the joint line is maximally reduced, and the overall performance of the swimsuit is improved.

The present application relates to a kind of trunks designed for the characteristics of breaststroke, belong to swimming clothing field, at least one of the problems such as poor drag reduction effect, low energy transfer efficiency, insufficient support performance, limited flexibility etc. when existing swimsuit is applied to breaststroke is solved.A kind of trunks designed for the characteristics of breaststroke, is made of stretch fabric, at least cover thigh and part of hip when wearing, with the side close to skin as the reverse side;The trunks include local pressurized area, tension band and joint seam.The trunks of the present application reduce the movement resistance in breaststroke, improve the energy conversion efficiency, provide sufficient muscle support, and ensure the flexibility of movement.

The utility model relates to the technical field of water sports equipment, and particularly discloses a flipper which comprises a shoe body and a paddle body. The shoe body comprises a vamp on the upper portion, a toe cap on the front side and a sole at the bottom, and the vamp, the toe cap and the sole jointly define a shoe cavity capable of containing the foot. One end of the paddle body is connected with the vamp, the other end of the paddle body extends outwards, the other end of the paddle body is bent towards one side of the sole at a certain angle, and a paddling cavity is formed in the connecting position of the paddle body and the toe cap; a reset reinforcing rib is arranged in the paddling cavity, and the shoe head and the paddle body are connected through the reset reinforcing rib. According to the utility model, the paddle body extends outwards and is bent towards one side of the sole at a certain angle, so that water flow can be grabbed more effectively, and larger thrust can be generated in the backward paddling process. Therefore, the swimming speed of the user can be increased in breaststroke or similar swimming actions, and physical exhaustion is reduced.

This invention relates to swim trunks designed specifically for the characteristics of breaststroke, belonging to the field of swimming apparel. It solves at least one of the problems existing in swimwear used for breaststroke, including poor drag reduction, low energy transfer efficiency, insufficient support, and limited flexibility. The swim trunks, designed for the characteristics of breaststroke, are made of stretchy fabric and cover at least part of the thighs and buttocks when worn, with the side closest to the skin being the reverse side. The swim trunks include localized pressure zones, tension bands, and seams. In breaststroke, the swim trunks of this invention reduce drag, improve energy conversion efficiency, provide ample muscle support, and ensure flexibility.

This invention discloses a swimming posture-assisted rehabilitation exercise trainer. An upper limb movement mechanism is connected to the left end of the central frame, and a lower limb movement mechanism is connected to the right end. The upper and lower limb movement mechanisms are connected and linked through a linkage mechanism on the central frame. An upper rocker arm and a lower rocker arm are connected to the left and right ends of the central frame, respectively. The rear end of an upper sliding rod is placed in the internal track of the upper rocker arm and can slide. A connecting groove is formed on the upper surface of the upper sliding rod and the upper rocker arm. The front and rear ends of the middle sliding rod are located on both sides of the central frame, and an upper connecting rod, a connecting rod push handle, and a lower connecting rod are coaxially connected to both the front and rear ends. The upper connecting rod is slidably and fixedly set in the groove. A backstroke pedal is slidably mounted on the lower rocker arm, and the lower connecting rod is connected and linked to the backstroke pedal through a rotating shaft. This invention has the technical characteristics of being able to use a multi-link mechanism to link upper and lower limb movements, allowing for autonomous or assisted backstroke and breaststroke limb movement training and rehabilitation.
