Telescopic racks provided in the upper parts of the sleeves. Racks are installed on the sled with the possibility of lateral movement on the cross rails. The rack is also installed with the possibility of longitudinal movement relative to the rails beneath the ground. Fixation of the slide relative to the cross rails in the transverse direction is performed by the stoppers. The seat is made rollaway. 11 Il.

The invention relates to a device for training the muscle system, in particular, to the formation of posture training run posture while sitting and standing pose in the static-dynamic mode.

The prior art research poses sitting on stools erect (A. C. Urwin, C. M. ZatsiorskiÓ. Ergonomic biomechanics. - M.: Mashinostroenie, 1989, S. 72-73, Fig. 2.17, D). It has been proved that from the point of view of minimizing the compressive strength (CS), acting on the lumbar-Kraut 420 N. The "lumbar lordosis (bending the spine forward) is saved and the person acquires a position corresponding to the bearing, which is usually considered the right...", because "the preservation of the lumbar lordosis causes the pressure in the intervertebral discs in this position is relatively small. However, the degree of muscle activity when this position is very high, so the pose is boring".

The prior art method and standing pose is proven that "from the point of view of minimizing the compressive strength (CS), acting on the lumbar-sacral joint, the optimal standing posture is relaxed posture standing" when the COP does not exceed 320 N. The person acquires the position corresponding to the bearing, which is usually considered the right..." (A. C. Aronin, C. M. ZatsiorskiÓ. Ergonomic biomechanics. - M.: Mashinostroenie, 1989, Fig. 2.17, A), because "the preservation of the lumbar lordosis causes the pressure in the intervertebral discs in this position is relatively small" (1, S. 75 (B). In addition, it is possible to trace the change of the lumbar curvature of the spine under different methods of cultivation (1, Fig. 2.18 A, B, C, D).

Known research vertikalno is encosta vertical body position" (C. S. Gurfinkel, J. M. Kots, M. L. Shik. Regulation of posture. - M.: Nauka, 1965, S. 196). "A clear definition of the norm of the vertical position of the body has not yet produced" (2, S. 8). The studies were conducted with healthy people in the pose them comfortable standing; calculations of bioelectric activity of the muscles and the distribution of muscle stresses are given only for this rack and results are explained by the biomechanical features of this rack. Research findings are mainly conjectural nature" (2, S. 111-118).

Installed, "active participation of various muscle groups in the provision and retention of the vertical posture is a dynamic task, even upon standing (2, 90 C.-100). The influence of dynamic, i.e., the variable part of the work of the muscles under the small amount of muscle tension, and by the intense tension prevails static component. Static load mode runs in the background of constant fluctuations (physiological) parts of the body and contains a dynamic component. These factors - fluctuations and the static-dynamic mode muscles is accompanied by strengthening their circulation" (3, C. 100, 104).

"Therefore, the static-dynamic is blagopriyatnyh conditions of circulation, because when poznaj muscle (active position) blood in them increases. Growing up, develop muscle efforts, an increase in the amplitude of action potentials, and increasing the load on the main muscle increasing share of work, and other muscles (2, S. 106, 110). One of the mechanisms poznaj activity - reflex on stretching the muscles working in postural mode. Sustainability poses a consequence of the interaction (biomechanical and reflex) of all muscles of the trunk and extremities, is determined by the ability of the neuromuscular system to minimize physiological fluctuations" (2, S. 73, 114).

Another source under the posture "refers to the habitual posture relaxed standing without active muscle tension and holding the torso and head straight" (M. F. Ivanitsky. The human anatomy. - M.: FIS, 1985, S. 398); hereinafter: "Saving vertical position by one of the passive elements of the locomotor system is impossible. Need more active involvement of the neuromuscular system, sufficient muscle tone, when movable relative to each other, the links included in the body, are held by tension of the muscles and ligaments in the docked state (3, S. 437).

Do not give unambiguous is the overall center of gravity is located approximately in the same vertical plane, in which lie transverse to the axis of the main joints of the extremities (shoulder, elbow, hip, knee and ankle) and the centers of gravity of the individual parts of the body (head, trunk and extremities) little convenient" (3, S. 438).

There is a drawing showing the distribution of muscle strains in different positions of the body in the standing posture, where quite clearly the advantages of anthropometric posture and obvious shortcomings of other ways racks that may cause physical defects, is the author.

In biomechanics one of the mechanisms poznaj activity is "reflex on stretching the muscles working in postural mode; stability, posture is the result of interaction (biomechanical and reflex) of all muscles of the trunk and extremities, but energetically expensive form of muscle activity provides relative neoteleostei with long-term conservation of natural POS (2, S. 73,114). The latter is determined by the ability of the neuromuscular system to minimize physiological fluctuations and, in turn, is supported by an active physiological mechanisms, i.e. possible treniruemoj and improvement" (2, S. 59). "Maintaining a vertical posture of the body as a ladder of constructively, having two points of support, ensure a sustainable balance balancing "the game" a large number of different groups of skeletal muscles" (N.A. Bernstein, 1990). "To ensure the vertical position of the body of man has multiple power reserve. This power buffer indicates the relative profitability of standing and plays a very important role in restoring the disturbed equilibrium" (2, 90 C.-100).

Do not give a clear understanding of the "correct" posture studies concerning the value of the reference circuit, the position of the legs and feet.

"In terms of the relaxed standing biomechanical indicators of height, weight and value of the support contour at the degree of resistance of the body visible influence. The angle formed by the longitudinal axes of the feet in terms of convenient hours, is in the range of 30-40o. The greatest stability in the value of this angle 30-45o( 2, s 48).

In another technical solution "square bearing with closed heels to be greater in the case when the feet are positioned relative to each other at an angle" (3, S. 437).

In "technical developments on the static stability of an equilibrium of the body" and "the formula and Tvout calculations for the position of the stop at different angles (Century. Petrov, Y. Gagin. Mechanics of sports movements. ): Pics, 1974, S. 74).

Reliable research about the position of the legs and feet in a sitting posture is not found.

The disadvantage of the prior art variations of postures sitting", "standing", "vertical position" is the low efficiency of known recommendations due to the fact that in these and other well-known publications theoretical explanation of different poses without explanation of the ways that can be sustained dynamic stereotype physiological posture.

The study of features of work with people that had problems with posture, allow to draw the following conclusions.

The claimed device for training on the formation of the posture with the position of mechanics is equivalent to the static-dynamic mode - sitting posture and standing posture acquire activity due to muscle tone, with each segment of the body regains mobility relative to another segment, supports its own weight by using stress of the muscles and ligaments" (3, S. 437), which contributes to improving the functioning of the body and of the individual author.

When using the claimed device of muscle tone is suf

The closest analogue of the claimed invention is a device for training for the formation of a bearing containing space for accommodating the feet of trainees and telescopic rack (see Yushkevich, Etc., etc. the Application of technology in education and training of athletes. - Minsk: the Flame, 1987, S. 91-94).

The technical result of the invention is:

- coordination of the vertical common center of gravity of the whole body (neck and head),

- improvement of the bone-ligament-muscle interactions,

- creation of training in sitting posture and standing posture stable dynamic stereotype posture with the maintenance of the physiological curves in the cervical, lumbar and thoracic spine with minimal compression forces in the intervertebral discs,

- creation of optimal conditions of stability of the body in a vertical position,

- creation of conditions under which each segment of the body regains mobility relative to another segment and supports its own weight, i.e., activation of POS,

- the formation of a conscious attitude to maintain a constant comfortable state of body from the standpoint of physiology,

- meeting the challenges of rehabilitation, the party,

- prevention of postural disorders.

This technical result is achieved by the fact that the known device for bearing formation containing space for accommodating the feet of trainees and telescopic stand according to the invention is equipped with reclining seats and guides fixedly mounted under the platform, with telescopic racks provided in the upper parts of the cuffs and installed on the sled with the possibility of lateral movement on the cross rails and longitudinal movement relative to the guide located under the deck, and the fixation of the slide relative to the cross rails in the transverse direction is performed by the stoppers.

Training is carried out as follows.

Trainee 1 in sitting posture is placed on the reclining seat 13, Fig.(2, 3, 4).

Trainee 1 in the posture of standing is placed on the platform 2 (Fig.6, 7, 8).

oto the floor or hips, or back to seat up until the knees and your toes will not be on the same vertical line; slight move five feet inside.

In the standing posture, the practitioner is situated on the site of the simulator, feet set so that the reference line passing through the middle of the heel and the middle of the 2nd toe of one of them, right for example, forms with the vertical line drawn through the middle of the body, the angle of 5-10oand the reference line of the left foot not more than 30owith vertical foot left foot towards the right push forward so that the midpoint of the edge of the extended heel of the left leg is at the level of the middle of the heel of the right leg, the distance between the heels no more than 3-4 cm (Fig.5).

At the preparatory stage of training in sitting posture and standing posture bother with considerable effort, not to shivering, muscles brushes, compressed in kolacic, hips, legs and feet, chin held horizontally, neck and head in the apical part of the pull up and the whole body. On the main stage, bent at the elbows to throw in different directions on each side, hands while tightly connect with the palms over the apical part of the head, all the fingers together, send up, the angle between the shoulders and forearms hands 90(+/-3)o. Shoulders fasten cuffs 4. At the final stage, release the shoulders from the cuff 4, the strain with the effort not to shivering, muscles brushes, compressed into fists, forearms bent at an angle of 90(+/-3)oto the shoulders, the shoulders, the chest, not arching her forward, back, abdomen, buttocks, hips, legs and feet, podborodok hold horizontally, neck and head in the apical part of the pull up and the whole body.

During the execution of each stage periodically slightly strain and relaxes the muscles of the buttocks and thighs, pruzina them, make a slight shift of the body within a fixed posture.

Each stage of the cycle (preparatory, main and final) perform 3-4 approach from 15 to 60 s each.

The effectiveness of the inventive method is confirmed pedagogical experiments and observing the th.

All the above confirms the possibility of implementing the claimed invention and with the expected sports-technical result. Athletes with an optimal dynamic stereotype of a high level of readiness, mobility, disability.

Optimal methods of medical-pedagogical control for individual state training are standard methods.
