Abstract

The invention makes it possible to increase the efficiency of training by adjusting the range of load forces in the inferior phase of movement. The device contains a shaft with a flywheel. A cable with a handle is attached to the shaft. There are additional shafts for covering the cable, installed parallel to the main one. Additional shafts can be prevented from rotating in opposite directions by ratchets. When locked, additional shafts work as rods. The friction of the cable on the rods alters the loading force on the athlete in both the overcoming and inferior phase of the movement. This forms the correct structure of motion and the power characteristic of uss. 1 hp f-ly. 2 Il.

The invention relates to sports equipment and can mainly be used for strength training of athletes-throwers, swimmers and cross-country skiers.

The purpose of the invention is to increase the efficiency of the training by adjusting the range of load forces in the inferior phase of the movement.

FIG. 1 shows the device, the first embodiment with one additional shaft, general view; in fig. 2 - the same in operation, the second version with two additional shafts.

The device comprises a rigid body 1 in which a shaft 2 is installed with a means for creating resistance to its rotation, made in the form of a flywheel 3, a cable 4 fixed on the shaft with a span of it with several turns and carrying the handle 5, and an additional one shaft 6 (first option versions) or several (second version) for cable coverage. The additional shafts have means for stopping them from rotating both in the direction of winding the cable (not shown) and in the direction of winding the cable on the main shaft (Fig. 1). These tools can be performed, for example, in the form of ratchet mechanisms. When locking additional shafts, they work as rods.

To perform the exercises, the device has fixed a cat on the wall or on the floor. The athlete pulls the cable 4 by the handle 5, accelerating the shaft 2 with the flywheel 3. The ratchet mechanism 7 (Fig. 1) allows the shaft 6 to spin, the cable does not slow down. When all the turns of the cable 4 are unwound from the shaft 2, the cable starts to be wound on the shaft 2 in the opposite direction, due to the inertia of the device. The shaft 6 will be locked by the ratchet mechanism 7 and the friction of the cable 4 on the shaft - rod 6 helps the athlete to slow down the movement. The athlete can measure his efforts so as to slow down the movement at the same point from which he started the overcoming movement. After that, the athlete can immediately start the next movement.

The use of the ratchet mechanism 7 having the possibility of switching, or the use of the shaft 6 rigidly fixed in the housing 1 allows to increase the inertial load in the overcoming phase, without changing or reducing the inertial load in the inferior phase of the movement.

A variant of the inertial device with two shafts 6 mounted in the housing 1 allows to obtain several variants of the circumference of the shafts 6 with a cable, which differ in the total angle of the circumference. This allows the inertial load to be adjusted. For example, when used as a cable

Kapron pinch of the device, in which two rigidly fixed steel shaft-rods parallel to the shaft are installed in different places of the body, allows to obtain values of the equivalent accelerated mass from 50 to 200 kg. This is sufficient for many training tasks. FIG. 2 shows four options: a, b, c, d, with an increasing angle of circumference.

The device allows you to alternate loads of different sizes when performing exercises in the same approach, for which you need to use the variant d of girth of the rod and shaft with a cable, shown in FIG. 2. At the same time, in the first, third and other odd movements, the friction of the cable on the shaft does not displace it, but in even movements it slows down the acceleration. In order for movement to be possible in this case, and the difference between alternating loads was not too large, 0. It is necessary that the angle between the pulling cable and the line connecting the centers of the shaft and the rod be 120-170 °.

The technical and economic efficiency of the proposed inertial simulator consists in the possibility of reducing the efforts made by the athlete in the inferior phase of the movement, this allows to increase the effectiveness of the training, as it brings the character of the movement on the device closer to the character of the main sports movement, which is not characterized by inferior work. The ability to relax in the inferior phase allows the athlete to perform a greater number of movements developing strength in each approach and in training.

The ability to adjust the ratio of the overcoming and the inferior load allows you to choose the value of the inferior load, which contributes to the optimal pre-stretching of the muscles of the athlete before performing the overcoming work.

A special way to increase the effectiveness of training is the method of using the proposed simulator with alternating load values, called the variable method of training. Previously, this method was used by athletes-throwers in the form of alternate throwing projectiles of different weights. The use of the simulator makes it possible to more closely approximate movements with different loads in time and, thus, increase the effectiveness of this effective method.

Reducing the load in the inferior phase of movement reduces jerks when performing exercises, increases the safety of use of the simulator.

This makes it unnecessary to use additional massive flywheels to regulate the load. This leads to a relatively small weight of the proposed simulator - up to 5 kg, and dimensions - up to 0.2X0.2X0.4 m.

The dimensions, low weight and low cost of the proposed simulator make it possible to use it at home.

The above qualities of the proposed simulator make it possible to recommend it not only for training athletes, but also for general physical training of athletes and in physical therapy.
