Description

The proposed utility model relates to devices for swimming, namely, equipment for recreational swimming, and is intended for training a swimmer.

The effectiveness of swimming largely depends on the technical level of the athlete and the development of the most significant physical qualities for this type, such as speed abilities, which directly depend on the traction in the water. An increase in the traction force of the swimmer's stroke and jerking movements is inextricably linked with the use of various training tools in the training process that contribute to their increase: shoulder blades, fins, braking devices, rubber cords, etc.

Of the known braking devices, the most commonly used are parachutes, a cup belt, shorts with special pockets (https://www.proswim.ru/article/aksessuary-dlya-plavaniya-s-soprotivleniem/, https: // temptraining. ru / si /). All of them create additional resistance due to drag and friction, forcing the swimmer to apply more force and thus develop the force of stroke and push in the water. Each known device has its own advantages and disadvantages. Often their use is associated only with a limited stage of the training process, as increasing the resistance in water with their help, you can disrupt the technique of stroke, slow down the necessary rhythm of movement, worsen the athlete’s “water feeling”.

The thematic patent search in the FIPS database http://www1.fips.ru/wps/portal/IPS_Ru, the NRIS database https://nris.ru/, and the PatScape database (http://patscape.ru/search/new) revealed devices - analogues that contribute to the increase in resistance to movement of the swimmer in order to train traction.

For example, a swimming device (patent US 2008O161167A1, published July 3, 2008), made of fabric material in the form of a dome-shaped "parachute" attached to the swimmer’s waist belt on a cord and located behind the swimmer under water.

A device for swimming (patent US 2004O197754A1, published 07.10.2004), containing a braking element in the form of a bucket with a removable bottom and the presence of a mesh ceiling at the bottom. The braking element is attached to the swimmer's lap belt on the cord and is located behind the swimmer under water. This device is taken as a prototype for the proposed utility model by the authors.

All the described devices for training a swimmer have an unchanged shape, the possibility of fastening on a waist belt for immersion in water behind the swimmer in order to create additional resistance in water to train traction and stroke in water.

The disadvantage of the presented braking devices is that they have a negative impact on the technique of swimming. The devices disrupt the process of uniform flow of water around the body during the swimmer’s movement due to the integrity of the structure. In addition, the listed devices slow down the movement due to the occurrence of overstrain in the shoulder joints, associated with the loss of a sense of support by the rowing surface of the hand. All of the above affects the structure of the stroke technique and violates the integrity of the swimming technique.

The task, developed by a useful model of a swimmer’s braking device, is to expand the arsenal of devices to train the strength of motor movements in water without breaking the technique and losing the “feeling of water” due to additional resistance when swimming.

The technical result of the utility model is to implement the purpose of the claimed device for training the strength of the arm stroke and pushing the legs in the water in full coordination of movements.

To solve this problem, a device is proposed containing movably connected annular segments of successively decreasing diameter. On the smaller ring-shaped segment, there is a mount for removable mesh overlapping, on the larger ring-shaped segment there are mounts for two removable handles. The device contains through holes for attaching a cable with a lap belt on both the smaller and larger annular segments. The device can be used to train the strength of the hand stroke and to train the force of the kick in the water.

The utility model is characterized in the figures.

The figure 1 shows a General view of the device with attached removable elements.

The figure 2 shows a folded view of the device with attached removable handles and mesh overlap.

In figures 3-4 shows the use of a device for training the strength of stroke by hand.

Figure 5 shows the use of a device for training kick force.

The device contains: from 1 to 4 ring-shaped segments 1 made of a material whose density is commensurate with the density of water, which helps prevent the device from dropping to the bottom and emerging of the device to the surface of the water. In this case, the diameter of the larger ring-shaped segment is not more than 250 mm, and the diameter of the smaller ring-shaped segment is not more than 100 mm, which allows using the device to take into account the physiological characteristics of the swimmer, without violating the swimming technique. The ring-shaped segments 1 are connected in series with each other by a cord 2, which ensures their mobility. Mounts for removable handles 3 are located on the larger ring-shaped segment, the mount for removable mesh floor 4 is located on the smaller ring-shaped segment. Through holes 5 for the cord 2 is made on each annular segment. Through holes 6 are made on the smaller and larger annular segments for fastening the cable 7 with a waist belt 8.

Examples of using the simulator:

Example 1

A swimmer, being in the water, puts on a waist belt 8, using a cable 7 connected to a braking device, which is made, for example, of polypropylene, placing the device underneath in the center along the body. Performing stroke movements, the swimmer pulls the braking device, applying additional efforts so that the cable 7 remains in a tense position (Fig. 3, 4).

To train the push force in the water, it is necessary to attach the removable handles 3 to the larger ring-shaped segment 1. The swimmer holds the device on outstretched arms in front of him. It is necessary to perform movements with legs and swim at such a speed that all the ring-shaped segments 1 of the braking device are in a horizontal position and do not hang down (Fig. 5). The braking device, due to its design, has a soft sparing resistance, allowing you to train traction in water without compromising swimming technique and excessive strain in the muscles and joints, as well as providing a uniform flow of water around the swimmer's body.

Example 2

To determine the effect of the braking device on the swimmer’s speed, a swimming time of 25 meters was recorded with and without the proposed device.

Assessing the strength of the hand stroke, swimmer “A” without a braking device by swimming method, the crawl on his chest overcame 25 meters in 13.2 seconds. However, using the braking device, swimmer "A" sailed the same way 25 meters in 15.1 seconds.

Assessing the strength of the push of the legs, swimmer "B" without braking device, working with his feet in the style of a crawl on his chest, covered a distance of 25 meters in 22.4 seconds. At the same time, with the braking device, swimmer “B” covered the same distance in 25.6 seconds.

In both cases, swimmers using a braking device noted sparing resistance to water without undue stress, while the swimmers retained a "sense of support", and tearing movements and movements with excessive stress were absent.

The proposed useful model of the braking device solves the problem due to the fact that:

- the design has ring-shaped segments, with a varying diameter from larger to smaller, sequentially interconnected by a cord, which ensures their mobility, while during swimming there is a uniform distribution of water along the body of the swimmer, which allows the swimmer to remain in a horizontal position, without unnecessarily immersing the pelvis and feet into the water, while swimming technique is not disturbed;

- the number of segments, as well as their diameter, can be changed depending on the required load, taking into account the physiological characteristics of the swimmer, which allows to achieve a positive effect of working with the proposed braking device for training the strength of hand stroke and the force of pushing feet in the water without disturbing the swimming technique for swimmers of different age category;

- the ability to attach a cable with a lap belt to both a larger ring-shaped segment and a smaller ring-shaped segment of the device allows you to adjust the strength of the water resistance, while reducing or increasing the muscle load of the swimmer, which is an integral part of training stroke power;

- the ability to use the device not only with a waist belt when immersing the simulator behind the swimmer in the water, but also by holding the device in the swimmer’s hands in front of him, thanks to the mount for removable handles on the larger ring-shaped segment, allows you to train the strength of the leg kick.

Swimming lessons with the proposed braking device are possible in any pool or pond under the guidance of a trainer, instructor or on their own. The design of the device can be mastered at the enterprises of the sports industry, manufacturing equipment for swimming.
