Description

one

The invention relates to sport, in particular to a butterfly training device for swimmers.

A device for training swimmers is known, which includes a support for the swimmer's body mounted on the frame, consisting of a horizontal section with straps for fastening the swimmer and a section inclined to it, and means for applying pressure on the arms and legs 1.

The disadvantage of this device, Q, is that it does not provide butterfly training.

The purpose of the invention is to provide butterfly swim training.

This goal is achieved by the fact that 5 in a known device for training swimmers, containing a support for the swimmer's body mounted on the frame, consisting of a horizontal section with straps for fastening the swimmer and a section inclined to it, 20 and means for applying pressure on the arms and legs , the support is made in the form of a two-armed lever, the axis of rotation of which is perpendicular to the longitudinal axis of the device while the arms of the lever are spring-loaded, and

One of the belts is fixed at the free end of the horizontal portion of the support.

In this case, the means for creating a load on the hands contains two shock absorbers fixed to the front pillar of the frame with hand grippers.

In addition, the means for creating a load on the legs comprises a frame mounted on the rear pillar of the frame and loops for placing the feet connected to the frame through opposite springs.

FIG. 1 shows the device, a general view; in fig. 2 - means of creating a load on the legs; in fig. 3 is a view along arrow A in FIG. one.

Claims (3)

The swimmer training device comprises a support 2 for the swimmer’s body mounted on frame 1, consisting of a horizontal section 3 with straps 4 and 5 for fastening the swimmer, and a section 6 inclined to it, and means for applying pressure to the arms and legs, the support is a double-arm lever, the axis of rotation of which is perpendicular to the prog of the axis of the device, while the arms of the lever are spring-loaded springs 8 and 9, and one of the belts 4 is fixed to the free end of the horizontal section 3 of the support 2. In addition, The handbands comprise two shock absorbers 11 and 12 fixed on the front pillar 10 of the frame 1, with the grips 13 and 14 for the hands (Fig. 3). In addition, the means for applying pressure to the legs comprises a frame 15 mounted on the rear leg 16 of the frame 1, and loops 17 and 18 for placing the feet connected to the frame 15 through oppositely arranged springs 19-24. The device works as follows. The swimmer rests on the support 2 with his stomach, fastens in clear 5 and shoulder 4 straps, inserts the feet of the legs in loops 17 and 18 and puts the grips 13 and 14 on the hands. Consider the device using the example of a two-shock integrated dolphin when the swimmer performs for one cycle of hand movements two kicks. In the holistic novelty, two periods are distinguished: the period of labor movements and the period of final and preparatory movements. In the first period, two phases are distinguished: the seizure and pushing with the arms with the movement of the legs up and the second - the repulsion with the arms with the feet down (the beginning of inhalation). In the second period, there are also two phases: the phase of sending the humeral arm and arms forward over the water with a movement of the legs upwards (completion of the inhalation), the second - the entrance of the arms into the water with foot strikes downwards. At the beginning of the push-up phase, the legs reach the surface of the water, and then as this phase is completed, the legs gently bend to strike the feet down. At the same time, from the position of the forward body, the arms are in front, the arms perform a rowing movement, gripping and pulling, are moved forward - to the sides - downwards. The athlete presses the palm of the hand on the grips 13 and 14 and stretches the shock absorbers of the 11 and 12 hands, testing and preventing their resistance. When the legs are flexed, the feet are gently upturned, the springs 21, 22 are relaxed and the springs 19, 20 are slightly stretched. The swimmer's body at the same time bends slightly in the hip joints. The horizontal portion 3 of the support 2 is lowered. The spring 8 is compressed, and the spring 9 is stretched, creating resistance to the body. X In the repulsion phase, the hands are repulsed with a sharp backward movement of the cysts and a simultaneous sweeping blow of the feet down. At the same time, the athlete sharply presses the cysts onto the grips 13 and 14 and even more stretches the shock absorbers of the 11 and 12 hands. With the stop moving back and forth, the spring 21, 22 expands upon impact, and the 19, 20 relax. With the support on the springs 19, 20, the support 2 turns on the axis 7 with the horizontal section 3 upwards. The spring 8 is thereby expanded, and the spring 9 is relaxed. This force of the spring 8 is transmitted through the shoulder strap 4 to the body of the swimmer and the muscles, the extensors of the trunk and legs receive an additional training force — an increased load. In the second period, in the phase of sending the humeral arms and hands forward and simultaneously lifting the legs up, the shock absorbers 11 and 12 of the arms relax as the hands are fed up through the sides after the movement is completed. The legs at the same time occupy the initial position for the second strike with the feet down. This blow comes at the entrance of the hands to the water and the beginning of the seizure. The muscles of the body are stretched. When the legs are lifted up, the springs 19 and 20 are again extended, and the springs 21 and 22 are relaxed. The support 2 at the same time again goes down by the horizontal section 3. The spring 8 at the same time relaxes, and the spring 9 tightens, creating additional resistance for the muscles - the torso flexors. Then the last phase is carried out - the entrance of the hands into the water with the blow of the feet down. Hands lightly press the grips 13 and 14 of the shock absorbers 11 and 12 of the arms, while the shock absorbers are slightly pulled. The feet are fed down and back, a second kick is performed. In this case, the foot dampers are again activated — the springs 21, 22 are tensioned, and the springs 19 and 20 are relaxed. The side springs 23 and 24 facilitate this movement and keep the feet on the swim line. The body of the swimmer at the same time is bent over the hip joints. In this case, the springs 8 and 9 of the base 2 are again activated, which in this case performs swinging movements on the axis 7. The interaction of the springs 8 and 9 at the same time contributes to the increased load on the flexors of the body and legs. Thus, coherent motor coordination is formed, the skill of which is improved during training. To increase the effect of training, develop flexibility of the body and strengthen the muscles that provide the work movement, a spring-loaded swing support is used, the swimmer transmits the force to it through the back and shoulder straps. When using the proposed device, the movements of arms, legs and torso are worked out in a single holistic swimming skill using the butterfly key and the corresponding physical qualities are developed - strength, endurance and others.
