Description

The invention relates to the field of sports, can be used in the preparation of runners for short distances and solves the problem of developing the special speed and power qualities of sprinters in the running mode.

During the run, the movements are performed in a ballistic type, when, sharply increasing activity, the muscle accelerates the individual links of the body on a short segment of the path, after which the movement is carried out by inertia. In movements of a ballistic type, the maximum muscular effort occurs at the moment corresponding to the initial part of the working amplitude.

The closest technical solution of the problem is a device for training sprinters, consisting of a leg installed with the help of the main belt on the sides of the upper biograft, guiding under the sliding weight, spring loaded on both sides with springs and connected to the additional belt on the bottom biopath with a cord . This device, depending on the mode of operation trains

speed-strength of the flexor muscles or hip extensors, excellence the ability to accelerate or inhibit the thigh in the flight phase of the run.

The disadvantages of this technical resolution are the following: the device does not allow in the structure of the running step to simultaneously improve the speed-strength qualities of flexors and extensors, i.e. the ability to simultaneously simultaneously accelerate and inhibit the hip, to flatten and dilute the hips in the structure of the stride; the weight of the device (especially sliding weight) negatively affects the runner's support reaction (the vertical and negative horizontal components of the support reaction increase, which leads to a pronounced drop in the running speed in the depreciation phase; the device does not allow improving the speed-strength characteristics of the muscles responsible for active reduction and dilution of the thighs in the cycle of the running step, overwhelming and gouging the tibia, bending the foot on the support.

The purpose of the invention is to increase the efficiency of training by changing the magnitude of the load in different phases of the running step.

FIG. 1 shows a device for training runners, a general view; in fig. 2-7

- the same, depending on the training regime, ki.

The device comprises a main belt 1 carrying a guide 2, made in the form of an arcuate tube with a longitudinal slit and two buffer springs 3 and 4 at the ends, an elastic cord 5, one end of which is connected to the guide through the spiral shaped element b, placed it is free in it, and the other carries an additional belt 7. Belts 1 and 7 are placed on the adjacent athlete's biogie. An arcuate guideline is designed to change the angle of thrust of an elastic cord and contributes to an increase in the accentuated part of the maximum muscle tension in the initial phase of movement of the biometric. The sliding element is needed to change the magnitude and direction of the elastic cord pull in different phases of the pitch.

The device is used as follows.

Figs 1 and 2 show the operation of the device in the directional development of the speed-strength qualities of the flexor and extensor muscles and the improvement of the ability to actively mix and dilute the hips in running.

In the initial phase of flight, when the leg is unbent (Fig. 1a), the sliding element is drawn by an elastic cord to the edge of the guide, located behind in the direction of movement of the runner. Bending of the hip and its advancement (FIG. 1 b) causes an increase in the thrust load of the elastic cord on the hip flexor muscles. Further advancement of the hip (Fig. 1c) changes the angle of gi with an elastic cord of a sliding element, which moves to the other end of the guide. In the result of the sliding element of the traction element, the load of the elastic cord does not interfere with the movement of the thigh (fig. 1a), but rather contributes to its forward-upward movement (fig. 1c, d). In this phase of the stride, the hip extensor muscles show greater activity, and hip deceleration begins, followed by active lowering to the support. At this point, the sliding element is located at the front edge of the guide (Fig. 1d, Fig. 2a), and the

The tightness of the elastic cord indicates the strain on the hip extensor muscles.

Further advancement of the hip in the supporting phase (Fig. 26, c) changes the angle of gravity with the elastic cord of the sliding element, and the latter slides along the guide to the other edge. This leads to a decrease in the magnitude and a change in the direction of the thrust rod (Fig. 2 d). The subsequent movement of the thigh forward again first increases the activity of the muscles responsible for acceleration during flexion of the thigh, saveM for braking during subsequent extension. Thus, the device improves the speed and strength of the muscles of the thigh and the ability to mix and breed hips in running.

FIG. 3 shows the operation of the device in the direction of improving the ability to overlap and gut the leg in the race. FIG. Figures 4 and 5 show the operation of the device in the direction of improving the ability of the thigh muscles of the supporting leg to withstand the inferior work depreciation of the running step, for which an additional belt is placed in the upper part of the lower leg below the knee.

At the moment of separation of the supporting leg from the track, the sliding element is displaced to the rear edge of the guide (Fig. 4a), T ha with an elastic cord at this moment is negligible. In the subsequent phase, the ko-de leg begins to bend at the knee joint (Fig. 46), and the elastic cord of the sliding element is absent, and under the action of a spring rigidly connected with the sliding element, is displaced to the front edge of the guide. In the front pitch phase, when the foot begins to fall towards the support (Fig. 4c, d), the elastic cord is gradually stretched, preventing movement of the foot towards the support. At the time of setting foot on the support and in the phase of depreciation (Fig. 5a, b), the load developed by an elastic cord on the thigh muscles is greatest. In the subsequent repulsive phase (Fig. 46, c), the sliding element slides sharply along the guide, and the pulling force of the elastic cord becomes negligible. Thus, the load created by the device is greatest in the depreciation phase, improves the speed and strength of the hip to the inferior work.

FIG. 6 shows the operation of the device in the directional development of the speed-power qualities of the muscles of the leg in the repulsion phase. At the beginning of the flight period, the foot of the jogging leg is completely bent at the ankle joint. The sliding edge is displaced to the edge of the guide point.

T ha of elastic cord in such a position of the foot is negligible. In the middle of the flight period, when the leg is bent at the knee and unbent at the ankle joints and propelled forward, the sliding element under the pressure of the spring is displaced to the edge of the guide at the toe. At the moment of setting the foot on the support, and especially in the repulsive phase, active bending of the foot begins, which is prevented by the increasing pull of the elastic cord. The flexion of the foot changes the angle of gi with the elastic cord of the sliding element, as a result of which the latter slides along the direction to the hem of the heel, and the load on the muscles of the flexors of the foot changes from the maximum at the beginning of the extension to the minimum at the end. Thus, the device trains the ability of the leg muscles to flex the foot on the support.

FIG. 7 shows the operation of the device, which contributes to the development of speed-strength qualities of the muscles of the lower limbs in the running mode. The selection of the stiffness of the elastic cords and springs, the shape of the curvature of the arcuate guide allows individually for each runner to select the load and the accented part of the amplitude of the movement of the bioprox, where the muscular effort is maximum in magnitude.

The simulator for sprinters contributes to the improvement of the ability to actively mix and breed hips in running, overwhelming and gouging the tibia, flexing the foot.
