Description

FIELD OF THE INVENTION The invention relates to sports equipment, in particular to training equipment for runner athletes.

The aim of the invention is to increase the objectivity of control over the technique of running.

The drawing shows a functional diagram of the device.

The device for controlling the technique of running contains the treadmill 1, the magnetograph 2, the compressor 3. the indicator 4, the accelerometer 5.

The device for controlling the technique of running runs in the 1 st way.

When running on tredbane 1, the accelerometer 5 generates an electrical signal, a hormonal acceleration of the conventional center of the mass from the 1-shift changer. In this case, for the conditional center of mass of the received point, located on the cross of the athlete. The signal from accelerometer 5 is fed to the input channel of the recording of magnetograph 2. Moreover, since the magnetograph 2 is made with a through channel, the playback signal is reproduced on the reproducing head with some delay (determined by the design of the magnetograph). The outputs of both end-to-end channel heads are connected to comparator 3, where they are compared in amplitude.

Since an indicator is connected to the output of the comparator 3 (for example, a voltmeter), the trainer (or the athlete himself) has the opportunity to see how the signal from the playback head of the through channel of the magnetograph 2 differs from the signal from the recording head of the magnetograph.

For example, if the signal from the output of the compressor 3 is negative, it means that the signal coming from the first high

the course of the magnetograph 2 Menbuie signal from the second output of the magnetograph 2.

If the signal from the output of the comparator 3 is positive, then vice versa.

In the change of signs of the signal from comparator 3, the information is laid down that the amplitude of the accelerations of the conventional center of mass of the stmp-smsp tends to increase (when, where Ki is the signal from the first output of the magnetograph; K, is the signal from the second output of the magnetograph) at K, Kg).

The change in the sign of the signal K (Kj is the signal from the output of the comparator 3) is controlled by the indicator.
