Abstract

A device for the operational control of the training process in athletics throwing using accelerometers, characterized in that accelerometers (acceleration detection sensors) are attached to parts of the athlete’s body, the acceleration of which must be measured, the wireless device is connected to a computer, and graphs are displayed on the monitor screen real-time acceleration.

Description

The utility model relates to the field of physical education and can be used in sports to achieve high results in athletics throwing.

Usually, the coach independently visually determines whether the athlete correctly or incorrectly performs certain technical actions that are necessary to achieve the planned result in athletics throwing [1]. A lot in this case depends on his experience and subjective understanding of the very essence of the training process.

However, due to the lack of an objective assessment of the performance by athletes of the entire technical action as a whole, as well as its components, each coach understands them in his own way, issues recommendations and corrects each throw based on his own ideas about the correctness or incorrectness of this type of technique. Hence the low results, and the duration of the preparation, and the inevitably occurring technical errors in the performance of the shots.

Closest to the technical nature of the claimed invention is a method of operational control of the training process, which consists in obtaining objective information about the movement of a sports apparatus (disk or core) directly during the training process. This information allows the trainer to promptly adjust the athlete’s technical training, to avoid gross errors that inevitably arise during visual observation, to achieve the planned result as soon as possible [2].

To register the acceleration of the distal (remote) parts of the athlete’s body, such as the wrist, tensometric accelerometers designed by G.I. Galunko were used. and Klimenko V.V. (developed in 1968).

The nature of the acceleration of the hand was compared with other biomechanical parameters of movements and electrical activity data of the main muscle groups, the biopotentials of which were measured using cutaneous electrodes.

The transmission of signals from accelerometers and cutaneous electrodes to the biopotential amplifier was carried out by wire, which is very inconvenient. Yes, and the recording equipment itself was large, so it was possible to control the actions of athletes when performing technical actions only stationary and only during the training process.

The objective of the utility model is real-time remote monitoring of technical actions in athletics throwing in both training and competitive modes, and prompt correction of detected technical errors.

The problem is solved by using sensors for determining the acceleration of body parts made from a combination of biaxial accelerometers and having relatively small sizes of -50 × 30 × 20 mm and operating from a standard 3-volt CR2 battery. To conduct the study, these devices are placed in a special case and fixed to parts of the body, the acceleration of which must be measured.

The accelerometer is synchronized with a personal computer as follows: a wireless device with an accelerometer (range of 50 m) is connected to a computer on the screen of which an acceleration graph in real time is displayed.

Examples of specific performance. To identify the spatio-temporal model characteristics for each muscle group, a study was conducted of the core pushers from the turn at the training camp in Moscow, preceding the 2011 Russian Track and Field Athletics Championships.

The participants of the experiment were members of the Russian national track and field team of the master of sports of international class of Russia in shot put Sidorov Α., Tsirikov S., Kokoev B. and honored master of sports of Russia Avdeeva T. At first they performed training attempts without accelerometers, then they repeated these attempts with using accelerometers. On the graphs, they clearly saw their own errors in the shot put technique. To eliminate them, the athletes performed specially selected exercises for each of them in order to correct the identified deficiencies.

The graph showed fluctuations in the acceleration of the projectile. There is a model curve to achieve the highest possible result. The real technique that each of the athletes demonstrated differed, sometimes even very significantly, from the one that was considered ideal.

The task of the experiment was to minimize deviations in the schedule of the training attempt, which was relatively ideal, which would increase the result, and specially selected exercises made it possible to quickly correct the discovered defects of the technique.

At the Russian Winter Championship, while performing competitive attempts at shot put, measurements were also made of the projectile acceleration oscillations. Obtaining information in the form of graphs of competitive attempts is the most valuable information for the correct construction of the individual training process of top-level sports athletes.

According to the results of this championship, all athletes significantly exceeded their results, and Avdeeva also became the European winter champion.

The inventive device allows you to clearly demonstrate to the coach and athlete the technical errors of movement when performing a competitive attempt and immediately correct them, which greatly increases the efficiency of the training process.
