Breaststroke land training device

Abstract

The invention provides a breaststroke land training device. The breaststroke land training device comprises a second hydraulic cylinder, an adjustable base, a fixed base, a sliding beam rod, a base plate, a communication soft tube, an adjustable throttle valve, a displayer, a first sliding block, a second sliding block, a third sliding block, two first hydraulic cylinders, two first connecting rods, two second connecting rods, two pedals and two stress sensors. According to the breaststroke land training device, specific air springs are adopted for providing imitation damp for athletes; double symmetric cranks share one sliding block mechanism; two symmetric congruent triangular structures are formed through the design; symmetric movement of the both legs is guaranteed; the standard breaststroke motion requirements are met; and the safety of a trainer is guaranteed when the breaststroke land training device is used. Three-layer type pedal plates creatively invented in the breaststroke land training device can guide footstep motions of the trainer according to changes of the force application directions of the legs; and synchronous and coordinated motions of the leg motions and the footstep motions can be achieved through the design that the footstep motions is guided by the leg motions. The invention further provides a breaststroke training method.

Problems solved by technology

[0005] Compared with the hands, the legs are stronger and more powerful, and they are the main source of propulsion for breaststroke, but at the same time, the flexibility of the legs is not as good as that of the hands, so it is more difficult to learn and master the leg movements

But most of the existing breaststroke training devices are only aimed at hand movements, such as Chinese invention patent CN200951304 breaststroke road practice simulator, etc., but the training effect for leg movements is not ideal
