Technical training of track and field athletes using an inertial simulator.

This review will look at another training inertial device for track and field athletes. With this device, you can perform movements that simulate the final effort of throwing and sprinting (while maintaining the structure of the sports exercise). The device is also used to develop speed-strength qualities of individual large and small muscle groups.

Installation resistance unit inertial simulator (see picture) is a shaft rotating in bearings. A set of disks of various diameters and a cross with weights (a set of weights from 1 to 5 kg) are attached to the shaft. Weights on the cross can be attached at three points. The disks have protrusions or recesses for attaching a cable or special cord. The entire resistance assembly is mounted on a frame, the base of which can be attached to the floor, wall or ground.

Methodology for technical training of track and field athletes on this device:

Technical training of track and field athletes using an inertial simulator is carried out as follows: The installation is located behind the athlete at a distance of 2...3 m from the starting line. The cable is wound around one of the diameters of the disk for the length of the segment being run. The free end of the cable is attached to the athlete's belt. The amount of weight is selected experimentally for each athlete depending on his individual characteristics, level of preparedness and objectives of the training session. An athlete can run from low (from the blocks) and high starts. Using a cable of various lengths (from 5 to 60 m), you can practice running with weights on any segment.

Depending on the weight of the load, the amount of resistance can be changed by winding the cable on different disks. The smaller the diameter of the disk, the greater the resistance, and vice versa. Rearranging the weights also changes the amount of resistance (if the weight is attached to the edge of the cross, the resistance increases).

As running speed increases, the load increases as long as the movement is accelerated, i.e. there is positive acceleration. This allows the athlete to vary the amount of load and speed during the movement.
