Technical Field

The invention belongs to the technical field of equipment for practicing breaststroke training, and particularly relates to a ground breaststroke action trainer.

Background

Along with social progress, the requirements on the living quality of people are higher and higher, swimming pools of communities, public places and schools are continuously improved, and swimming becomes a part of people for reducing living pressure, exercising bodies and entertaining. Breaststroke is a swimming posture simulating the swimming action of frogs, is also the oldest swimming posture, is simple and easy to learn, and most of the initial swimming learning is from breaststroke. The breaststroke process mainly comprises three parts of leg-folding, foot-turning, water-clamping, body-keeping smooth and stable, and water-holding and air-exchanging by the clamping arms.

In order to quickly and accurately master the action of breaststroke, the following technical scheme is commonly adopted in the prior art:

chinese patent application 200520144451.9 discloses an auxiliary hand float for practicing frog swimming, which comprises a float body made of foam plastic board, and a device for fixing hand is arranged on the float body. The hand fixing device is a rubber belt fixedly connected to the floating body, or four finger holes which are arranged on the floating body according to the sequence characteristics of human fingers. The auxiliary hand float can enable most students to master the requirements of breaststroke in a short time. With the help of the hand float, long-distance water stroke exercise can be quickly carried out, so that the breaststroke hand is easy to stroke, and the interest of beginners in swimming is improved.

Chinese patent application 201420869776.2 discloses a side-turning prevention full-floating breaststroke leg exercise floating plate, which comprises a floating plate body, side wing plates and a hand grip, wherein the side wing plates are arranged at two sides of the floating plate body, and the side wing plates are symmetrically arranged; the two grippers are symmetrically arranged and are arranged on the front side of the floating plate body. The floating plate is more reasonable in shape, larger in size and buoyancy, and capable of preventing side turning, providing a stronger sense of safety for a beginner swimmer, and remarkably improving buoyancy and swimming aid effects.

However, the existing breaststroke action training scheme is that a floating plate or a hand float is suspended in water, and then breaststroke actions are exercised, so that the body part of an exerciser is underwater, which influences a coach to observe the actions of a student and is not beneficial to the coach to guide corresponding normative actions; the other is convenient, the processes of leg folding and clamping arms lack corresponding resistance training, which is not beneficial to better enhancing the training effect of breaststroke.
