Description

The invention relates to sports simulators and is intended to train athletes to increase the speed of hand movements and gain high-speed endurance, including when practicing martial arts, in particular boxing, hand-to-hand combat, kickboxing, in general, for training fighters of shock styles. In addition, it can be used in rehabilitation after injuries and recovery procedures in athletes.

There are a large number of sports equipment for training athletes in martial arts, in particular "pears", see Boxing, Textbook for the institutes of physical education. Μ., Physical Culture and Sports, 1979, p. 249, fig. 38-40. In these devices, the “pear” is attached vertically or horizontally with a spring and / or an elastic cord.

Boxing mannequins are also known, see fig. 35, 36 on p. 247 of the above book, designed to form skills of tactical and technical actions at certain distances.

The sports equipment is widely known as a boxing bag containing an inertial mass fixed to a flexible suspension, the surface of which is coated with wear-resistant material, and one end of a flexible suspension is fixed to a fixed base at the top, for example, on the ceiling, and ropes, chains or ropes [2].

However, these training devices, initially aimed at forming the skills of powerful shock movements, do not provide a progressive increase in speed endurance and speed qualities of striking an athlete.

The closest in technical essence is the well-known hand trainer [3], which includes a frame, a loader in the form of an electrically controlled brake with a shaft and a working lever with a handle.

The disadvantage of the prototype is the impossibility of producing high-speed qualities in direct strikes in athletes drummers.

The disadvantages of the analogue and prototype can be eliminated by the fact that in a sports apparatus for developing the speed of movement of the hands, containing with the ability to move the device for wrist holding by a trained athlete,

the device for wrist holding by the trained athlete is made in the form of a handle mounted with the possibility of rolling on the crank pin of the crankshaft mounted by the main journals with the possibility of rotational movement in the sliding bearings fixed on a fixed base, the crankshaft is driven by a rotary drive mounted on a fixed base by mechanical transmission, and drive control system located on a fixed base, while the axis of rotation of the crankshaft ra It relies at an angle to the vertical location of the athlete, and the device is arranged to hold the wrist at the level of the athlete's shoulder.

This technical solution allows for cyclic movement with a given frequency of the athlete’s hand relative to the fixed base on which it is located.

In addition, such a technical solution allows the athlete to develop the speed qualities of the muscles involved in a direct and lateral impact.

The help of the simulator during movement of the arm allows the athlete to feel his maximum individual speed of movement, while the parameters of arm movement are “recorded” and stored in the so-called muscle memory, which later allows him to feel and understand his limits and capabilities in speed, compare them with rivals and make the right decisions in battle based on the speed of movement and strike.

In addition, adjusting the frequency range of the drive over a wide range of human capabilities allows you to quickly determine the ultimate capabilities of the trainee and select individual programs for the development of high-speed qualities upon impact (and not only) and high-speed endurance. It is obvious that drive 6 can implement cyclic training programs, including when the frequency increases, stabilizes, decreases according to different time laws.

Placing the axis of rotation of the crankshaft at an angle to the vertical from the location of the athlete allows you to approximate the trajectory of the athlete’s hand to the real one upon impact.

The invention is illustrated in the drawing, where in FIG. 1 shows a side view of the inventive simulator.

A sports projectile for developing the speed of movement comprises a single-stage crankshaft 1 mounted for rotational movement, mounted with a possibility of rotational movement in the sliding bearings 2, mounted on a fixed base 3, a device 4 for wrist holding by a trained athlete is fixed on the connecting rod neck of the crankshaft 1 .

The crankshaft 1 is driven by a rotary drive 5 mounted on a fixed base by means of a mechanical transmission 6.

The movement of the crankshaft 1 with the handle 4 is provided by the control system 7 of the drive 5, located on a fixed base 3.

In this case, the axis of rotation of the crankshaft is located at an angle to the vertical from the installation site of the athlete.

There are adjustment options for the growth of the athlete and the length of his arm (not shown in the drawing).

Training on this sports equipment is carried out as follows. The simulator is positioned so that the handle is at shoulder level or just above the athlete’s chest.

The athlete takes the handle 4, which he can safely release in case of an emergency, turns on the drive 6 with his free hand. The crankshaft 1 is rotationally driven. The rotation speed is set that corresponds to the maximum or close to maximum for this athlete, depending on the chosen training program. The direction of rotation of the crankshaft during training for the right hand is counterclockwise, while training for the left hand is clockwise (or as in boxing, side impacts should go inward of the sector in front of the athlete).

The control system 7 of drive 5 has the ability to smoothly (keyword) change the frequency of rotation of the latter from 0 to 5 or a little more than Hz with an interval of 0.1 Hz. The choice of the upper limit of the range is due to the fact that a boxer of a high level of training, for example, a master of sports, is able to inflict 8 hits from two hands in 1 second. Accordingly, with one hand - 4 strokes per second. Note that a beginner starts at 2 beats per second.

A feature of the simulator is that it carries away the athlete’s hand and the parts of the body involved in the impact with a frequency slightly higher than the athlete himself can realize. This circumstance allows the trainee to expand his frequency range of striking, and therefore, increase the speed of striking, which in turn affects the striking power of an athlete-striker.

Classes on the simulator can be held in the mode of overcoming (resistance), when the athlete actively resists the movement of the handle.

The frequency of movement of the handle in this case is set significantly or below the individual maximum.

Using the simulator strengthens the athlete's motor skills when applying side and direct blows, and allows the athlete to develop the speed qualities of the muscles involved in a hand strike.
