Description

The invention relates to devices for performing exercises that are similar in structure to the competitive movements of gymnasts and swimmers of various specializations, and will be applied in the field of physical culture and sports.

The aim of the invention is to expand the range of muscles being trained and the nature of the load.

FIG. 1 shows the device, a general view; figure 2 is the same, view of side /; Fig 3 is a view of A in Fig.2; figure 4 - view B in fig.Z; Figure 5 shows a manual support option; Fig b - the device in use, front view; figure 7 is a device with a manual support; on Fig - when training gymnasts on the rings and the crossbar; Fig, 9 - the same, when training swimmers using the crawl, dolphin and breaststroke methods.

The device contains a movable bracket 1, which has the ability to rotate around the axes of the sleeves 2 located in the vertical rack of sector-shaped brackets 3 fixed at the base A. The arcuate portion of the sectors is made toothed. Bracket 1 carries guide rails 5, on which trolley 7 is installed by means of rollers b, having a bracket on the lower part carrying a package of removable goods 8 and equipped with a pair of tied belts 9. There is an eyelet on the front part of the trolley for hooking the counterweight cable 10 11, thrown over a block that is fixedly mounted on the crossbar 12, which closes the guides on the upper side and has a number of holes 13. On the same crossbar there are brackets 14 that can move along the crossbar and rotate around it, fixed by means of stoppers 15. At the ends of the brackets 14 there are blocks 16 (FIG. 2), through which exchangeable cables 17 are thrown, having toggles on the free ends for fastening special nozzles: gymnastic rings 18, crossbars 19, plates 20 for supporting the cysts when imitating a swim g ae kn mix driences. Second

The end of each cable is attached to vibroplatform 21c by grooves 22 for accommodating rollers 23 with handles 24.

To shelves 25 brackets 1 top and bottom

electric motors 26 and 27 are attached, the shafts of which by means of gears engage with the gear sections of the brackets 3. Electric motors and vibrating platforms are turned on and off with

remote control 28 control.

The vibrating platforms (Fig. 3) are moved along the frame 29, fixed in the desired position by the stoppers 30. The frame has bushings 31 and 32, making it possible to rotate it together with the vibrating platforms around the axis OX. The tilt angle of the frame is fixed with the help of the stoppers 33, which enter the matching holes on the half disk 34, attached to the vertical stand

sector bracket 3 and vibroplatform frame.

On top of the vibrating platforms, nont echinya 35 can be additionally laid, having parallel handles 36 and plates 37 for supporting the vibrating plates.

The effectiveness of the device on the one hand is due to the possibility of using vibration as a stimulating factor when performing special exercises in gymnastics and swimming, which completely reproduce the structure of competitive movements. The training effect of vibration directed along muscle fibers (so-called biomechanical stimulation) consists in enhancing the blood pumping function of muscles and simultaneously activating a larger number of motor units, which affects muscle strength in the sense of increasing it and enhancing the proprioceptive ig-pulsation that creates conditions for the accelerated formation of a dynamic stereotype, which affects the learning process in terms of its acceleration.

In addition, the effectiveness of the device

This is due to the ability to locate the molecule in different initial positions and to make different combinations of the tilt angles of the guides and the vibroblock relative to each other and relative to the floor - independently of each other.

The combination of these angles of inclination makes it possible to select any initial positions, which opens up broad possibilities for the differentiation of training loads in the sense of their selectivity with respect to different groups of muscles or different bundles of the same muscle; perform exercises (for example, a gymnastic cross) in full accordance with the competitive movement in kinematic characteristics, but in lighter conditions — for example, with a tilt angle of 45 °. The major disadvantage arising in this case — a significant difference in the dynamic characteristics — is leveled out by the use of vibration, which in this case acts as biomechanical stimulation. The latter models a maximal muscular contraction mode.

Gradually, the athlete’s initial position when doing the exercise is to bring the cross to a natural vertical position. Moreover, the effect of biomechanical stimulation is such that the athlete can perform an exercise of the cross under normal conditions even before he does it on the proposed device. Having performed the cross in an upright position on the simulator, an athlete can be sure that in the natural conditions of competitive activity he is able to perform this exercise easily and freely and include it in the combination more than once.

The device works as follows.

PRI me R 1. Training strength of the pectoral and deltoid muscles of gymnasts.

Before starting the exercises, the bracket 1 and the carriage 7 are in a horizontal position. Depending on the fitness of the athlete and the goals of the training session, exercises are selected (Fig. 4, a, b, c). The athlete must hold the hands together in front of the chest or above the head, grasping the arms of the rollers 24 with the hands 23.

Training by means of a toggle switch on the control panel 28 switches on the vibroplatforms 21, then lays down on the trolley 7 by breast, seizes the rollers of the rollers with cysts and performs cleansing hands until fatigue occurs. In this initial position (torso horizontally), the pectoralis major muscles, the front fascicles of the deltoid muscles (fig.b) are stimulated.

Then the athlete, either by himself or with the help of a trainer, is fastened to the cart with belts 9, on the remote control 8 an electric motor 27 is turned on, raising the guides by an angle of 30 °.

The athlete tries to perform one movement. Depending on the subjective feeling, the magnitude is chosen from the oppression of the counterweight 11 or the weights 8. At the same time, it is due to the fact that the athlete

0 should receive such a load, at which he will be able to perform the exercise 2-4 times (when bringing up absolute strength) and 12-15 times (with the direction of training for strength endurance).

5 In the third approach, the angle is increased to 45 ° (Fig. Bb). The changes are changed according to the above principle. At this initial position of the body (at an angle of 45 °), the anterior and

0 middle bundles of deltoid muscles, upper bundles of trapezius muscles.

In the next approach, after resting, the guides are mounted vertically. The athlete performs the reduction of hands over

5 head, coming to the handstand (fig.bv). In this case, the middle ligaments of the deltoid muscles, the upper and lower ligaments of the trapezius muscles are stimulated.

The principle of alternately working out different muscles (or different bundles of the same muscles) during a single workout by changing the angle j of the body relative to the support is also used when performing flexion-extensory exercises with the use of a removable crossbar 35 (Fig. 7).

After the end of the exercise, the athlete turns off the vibroplatforms, turns on the electric motor 26, which lowers the guides to a horizontal position.

PRI mme R 2. Doing exercise cross on the gymnastic rings (fig.ba). In this exercise, an athlete through hand movements must

5 move the fan body from the position of the hang until the arms are horizontal (cross).

For the exercise, first, a cable 17 of the required length is selected, to

0 the free end of which is attached to the gymnastic rings 18. The brackets 14 on the crossbar 12 are oriented in the upward direction (FIG. 2), set at shoulder width, and then fixed with stoppers 15.

5 After that, the athlete rests on a horizontally positioned trolley 7 and fastens the belts 9. Then, using the console 28, the athlete (or trainer) turns on an electric motor 27, lifting the frame at an angle of 30 °, after which they turn on vibrating platforms, which vibrate from the cables to the rings. The athlete then takes the rings with his hands and performs the described exercise until fatigue occurs.

As fitness improves, the angle of inclination of the guides should increase up to a vertical position. The magnitude of the counterweight is selected each time so as to balance the carriage. After the athlete has the freedom to perform the cross in an upright position, additional ones may be applied 8.

Similarly, the exercises for swimmers shown in Figures 9a, b, c.

The amplitude of the vibrator movements is 4-5 mm, the vibration frequency is 26 Hz.
