Description

The invention relates to the field of sports, namely to sports rowing of a group of rowing vessels, and can be used during training for control and high-quality and timely correction of the training process of athletes-rowers.

At present, in our country and abroad, a search and development of instrumental means for monitoring individual parameters of training loads or indicators of individual body functions is underway. However, some developments are suitable only for scientific purposes, others - only for limited practical application.

Italian specialists E. Ruffaldi, A. Filippeschi developed a virtual environment with feedback technology, which allows identifying the classical model of highly qualified rowers' technique, as well as increasing the efficiency of training [Ruffaldi E., Filippeschi A. Structuring avirtualenvironmentforsporttraining: Acasestudyonrowingtechnique // Robotics and Autonomous Systems. - 2013. - No. 61. - P. 390-397].

Canadian scientist George W. has developed a method for presenting information about boat speed using auditory feedback, which makes it possible to increase the effectiveness of the training process [George W. Concurrent versus delayed feedback: biomechanics in rowing // 31 International Conference on Biomechanics in Sports (2013): Editors : Tzyy-Yuang Shiang, Wei-Hua Ho, Peter Chenfu Huang, Chien-Lu Tsai. - Taipei, Taiwan, July 07 - July 11, 2013].

F., Vilas-Boas J.P., Vaz M. проведен анализ силовых характеристик элитного байдарочника в условиях гребли на воде. Применение тензометрических датчиков в двух плоскостях с использованием беспроводной системы передачи данных обеспечило получение более детальной информации о силах, прилагаемых к рукоятке весла. В другой их работе проведен анализ ускорения одиночных и командных байдарок [Gomes В., Viriato N., Sanders R.,

F., Vaz M., Vilas-Boas J.P. Analysis of single and team kayak acceleration // Portuguese Journal of Sport Sciences. - 2011. - 11 (Suppl. 2). - P. 255-257]. Применение трехмерного акселерометра позволяет осуществить эффективную оценку ускорения и изменения скорости байдарки, обеспечивая возможность исследования вариации скорости при выполнении гребного цикла. Однако существует сложность визуальной регистрации и анализа движений лопасти весла при подводной фазе гребка.Portuguese specialists Gomes V., Viriato N., Sanders R.,

F., Vilas-Boas JP, Vaz M. an analysis of the power characteristics of an elite kayaker in rowing on water was carried out. The use of strain gauges in two planes using a wireless data transmission system provided more detailed information about the forces applied to the oar handle. In their other work, an analysis of the acceleration of single and team kayaks was carried out [Gomes V., Viriato N., Sanders R.,

F., Vaz M., Vilas-Boas JP Analysis of single and team kayak acceleration // Portuguese Journal of Sport Sciences. - 2011. - 11 (Suppl. 2). - P. 255-257]. The use of a three-dimensional accelerometer allows an effective assessment of the acceleration and change in the speed of the kayak, providing an opportunity to study the speed variation during the rowing cycle. However, there is a difficulty in visually recording and analyzing the movements of the oar blade during the underwater phase of the stroke.

Wainwright V., Cooke S., Low S., using the developed system, measuring the registration of the force acting on the oar, and acceleration, and comparing the video recordings of rowing of international kayakers, it was established that each of the rowers used an individual rowing style [Wainwright V. , Cooke S., Low C. Performance related technique factors in Olympic sprint kayaking // 33 International Conference of Biomechanics in Sports: Editors: Floren Colloud, Mathieu Domalain, Tony Monnet. - Poitiers, France, June 29 - July 03, 2015. - URL: http://isbs2015.sciencesconf.org/57200/ (date accessed: 15.01.2019)]. This must be taken into account in order to increase the effectiveness of performances.

The overwhelming majority of domestic works reflect the results of measurements of individual parameters of training activity, made after the end of the load or in the process of testing procedures.

In the work of Verlina I.N. substantiated effective options for organizing the training process of rowers in terms of regulation of specialized loads based on the analysis of the interdependence of their volumes, intensity, orientation and dynamics of recovery indicators, which made it possible to qualitatively control the training process [IN Verlina. The structure of microcycles aimed at developing the endurance of kayak rowers for 14-15 years in a one-year training cycle: Dis. ... Cand. ped. sciences. - Krasnodar, 1997. - 109 p.]

Zamotin T.M. substantiated effective approaches to the formation of individual trajectories for the development of special power qualities of rowers-kayakers on the basis of biomechanical and correlation analysis [Zamotin T.M. Substantiation of individual training trajectories in special strength training of rowers-kayakers at a special preparatory stage of the training cycle: Author's abstract. dis. ... Cand. ped. sciences. - St. Petersburg, 2013. - 23 p.]. At the same time, data are presented that testify to the effectiveness of using the organization of the training process of rowers on the basis of the provisions of the theory of the controlling external environment.

Most of these methods and techniques are based on receiving urgent information only after completing a training or competitive load. This is mainly due to technical difficulties. Only for certain parameters (heart rate, basic biomechanical parameters), their registration is carried out online.

Known "Method of correction of biomechanical parameters of command rowing technique" (US Pat. RU No. 2630436), intended for training and training of sportsmen-rowers on sea yachts, coordinated, synchronous work as part of the crew of a sea yacht on land, in conditions as close as possible to the training process, carried out on the water. This method consists in the fact that with the help of a program-control device, additional external loads are created that simulate the resistance of the aqueous medium. According to the invention, rowing simulators are preliminarily combined into a local computer network and connected to a computer, sensors are installed on the simulator and athletes' legs. After that, the individual biomechanical parameters of rowing locomotion of each athlete are measured and memorized, the generalized group indicators of biomechanical parameters are calculated, which determine the upper and lower boundaries, as well as the average value of the ideal model of the team rowing team technique, during the race for each of the variable conditions, they are measured and memorized in the memory array, the current individual biomechanical parameters of the rowers, the group current biomechanical parameters are calculated and compared with the average value of the ideal model of the team rowing technique of the crew.

The disadvantage of this method is the inability to timely correct the parameters of the rowing technique during training due to the fact that the model is calculated before the start of training and cannot be changed during training, all results are processed after the completion of training, and also due to the lack of feedback between the coach and the rower.

The closest technical solution is the "System of training analysis of rowing training" (international patent application (PCT) No. 201911381658.0, filing date 12/27/2019, publication number 110841263). This training analysis system includes a device for collecting data on training parameters and a device for collecting data on the physiological characteristics of athletes. In this case, a device for collecting data on training parameters is used to measure parameters about the state of individual athletes during training and can be used to transmit parameters about the state of each athlete to the terminal upon receiving data. The physiological data collection device is designed to collect physiological data from individual athletes and transmit them to a data terminal. The data transmission terminal is used to receive data on the parameters of the training and physiological state and transfer them to the system server. The system server can be used to generate an appropriate training analysis report based on the training and physiological parameters of each athlete. This training analysis system provides an analysis of the most important components of rowing training. We take it for a prototype. The disadvantage of the prototype is the lack of timely correction of the parameters of the training load of a group of athletes during training, since a report is generated based on the results of training, and its analysis is carried out after the completion of training, in addition, there is no feedback between the trainer and the rower.

Thus, the issues of improving the methods of operational control and management of training loads are of particular relevance at the present time.

The technical result of the claimed method is the correction of the parameters of the training loads in real time in accordance with the tasks set by the trainer to achieve the required effectiveness of the training of athletes-rowers.

The achievement of the technical result is ensured by the fact that in the well-known training system for analysis of rowing trainings, which consists in the fact that with the help of devices equipped with software, data are collected on the parameters of training loads and data on the physiological parameters of individual athletes during training, the transfer of the obtained data to the group athletes on the system server, according to the claimed method, before launching, in a group of rowing vessels along their central longitudinal axis, client computers with built-in software are installed, and the training parameters are downloaded to the client computer before it starts and controlled automatically or manually ; then the client computers are connected to a local network using a trainer computer, additionally equipped with an information display device, with server software; at the same time, the athlete is equipped with a chest module that includes a group of sensors with wired and wireless connections and a voice detector; after which the client computer is started; then the coach assigns the conditions of the parameters of the training load individually to each rower, and the training in the water area is carried out in three stages, including warm-up, main part and cool down; then the main part is divided into several segments, at each of which the athlete performs training with the given parameters of the training load; in the monitoring mode of a group of athletes, transfer and collection of the received training load parameters data to the system server, memory accumulation and information processing of individual athletes during training are carried out, and the training load parameters are recorded with a discreteness of 5-10 s; the server of the trainer computer provides visual information on the screen of the information display device; after which the trainer, from his workplace, selects the vessel of the controlled athlete in the process of arrival, at each segment of the distance in real time, visually monitors its position in the water area and the parameters of the training load: speed, pace, distance traveled and physiological parameters of the athlete, corrects them with the help of messages from the voice detector, generated by his commands, and if the physiological parameters of the rower are critically exceeded, the detector is triggered automatically or manually by the coach's decision.

The causal relationship between the essential features of the invention and the technical result is as follows.

Before launching, a client computer is installed on the rowing vessel with the loaded parameters of the current training before its start and controlled automatically or in manual mode, which provides network identification of the rowing vessel, at a preset network address, transmission of a packet of signals about the current position, parameters movement. In addition, the client computer, in contrast to the known solutions, provides the formation within the rowing vessel of its own Bluetooth zone for connecting the individual physiological sensors of the athlete and the voice detector, which allows creating feedback with the rower and adjusting the parameters of training loads in real time.

The sensors in the athlete's chest module provide pickup and transmission of signals about the individual physiological parameters of the athlete via Bluetooth to the client computer of the rowing vessel for further processing and transmission to the trainer terminal. This configuration, in contrast to the known ones, allows not only to provide an individual or standard set of sensors, but also to correct the parameters of training loads in real time.

The voice detector generates standard voice messages. In contrast to the known solutions, the detector is automatically triggered when the physiological parameters of the rower are critically exceeded, or in manual mode, depending on the current training parameters in real time, as decided by the trainer.

The client computer with a discreteness of 5-10 seconds generates a packet of information about the parameters of the movement of the rowing vessel and the physiological parameters of the athlete for transmission to the trainer terminal. The discreteness of the transfer is selected programmatically and is determined based on the number of simultaneously involved client computers in order to exclude the loss of information. In the intervals between sending information packets, the radio channel of the client computer is in the mode of receiving commands from the voice detector.

Thanks to the new set of essential features in the claimed method, operational control and timely correction in real time of the parameters of the training load of the rowers of a group of rowing vessels is achieved, which ensures the achievement of the claimed technical result and allows to expand the arsenal of methods for this purpose.

An example of the implementation of the method.

Before launching, client computers with embedded software are installed in a group of rowing vessels along their central longitudinal axis. Moreover, the training parameters are downloaded to the client computer before it starts and are controlled automatically or manually. Then the client computers are connected to a local network using a trainer computer with server software, additionally equipped with an information display device (Fig. 1).

At the same time, each of the athlete's group is equipped with a chest module including a group of sensors with wired and wireless connections and a voice detector (Fig. 1). Accelerometer, GNSS receiver (multisystem GPS / GLONASS / Galileo), physiological sensors (heart rate, oxyhemogram) are used as sensors. Then the client computer is started.

The coach set a common goal: the development of distance endurance. Then the trainer assigns the conditions of the parameters of the training load individually to each rower at the race distance: speed, pace, distance covered and physiological parameters. Moreover, training in the water area is carried out in three stages, including a warm-up, the main part and a cool-down.

During the race, the coach selects the rowing boat of the controlled athlete from his workplace and determines the number of races.

The claimed technical result is confirmed by the training data of a highly qualified rower lasting 1 hour 15 minutes.

FIG. 3 shows the parameters of the load during training.

In the monitoring mode, the received data of the training load parameters are transmitted and collected to the system server, the memory is accumulated and the information is processed, and the training load parameters are registered with a discreteness of 5 s. In this case, the server of the trainer computer provides visual information on the screen of the information display device in real time.

The first stage is a warm-up, the athlete spends for 20 minutes.

Further, in the main part of the training, the rower goes four times a distance of 750 m. On each segment in real time, the trainer visually monitors his position in the water area and the parameters of the training load (Figs. 2, 3), and corrects them using messages from the voice annunciator , formed by his commands (Figs 4, 5, 6, 7).

In the first segment, the task was to keep the pulse rate at 140 beats / min while maintaining the amplitude and power of the stroke. The change in the recorded parameters of the rower's load on the first segment is presented in Table 1. Correction (control actions) from the side of the trainer is shown in Fig. 4. After marking the distance of 250 m, the athlete's heart rate began to decrease below the set level. The coach gave the command to increase the rowing pace in order to raise the pulse and keep it at around 140-142 beats / min. This was done, although in the last hundred meters of the distance the athlete again could not keep the set pulse and the pulse dropped to 136 beats.

On the second segment, the task was set to maintain the speed of 11.5-12.0 km / h due to the power of the stroke. The change in the recorded parameters of the rower's load on the second segment is presented in Table 2. Correction (control actions) from the side of the trainer is shown in Fig. 5, which shows that when solving the task of maintaining the distance speed of 11.5-12.0 km / h at the distance from 250 m, the athlete's speed began to decrease. The coach gave the command to increase the speed and keep it within the established limits. As a result, the rower managed to accomplish this and maintain it until the end of the segment.

In the third segment, the task was set to maintain the pace of 75 strokes / min and the boat's steady motion without spurts (jerks or a sharp short-term increase in the pace of movement). The change in the recorded parameters of the rower's load on the third segment is presented in Table 3. Correction (control actions) from the side of the trainer is shown in Fig. 6., from which it can be seen that when passing the distance, starting from 350 m, there was a decrease in the pace, and by 450 m the pace dropped to a critical mark - 71 strokes / min. At a distance, when passing the 500-meter mark, the coach gave the command to the athlete to raise the pace to the set level. The athlete managed to accomplish this task.

In the fourth segment of the distance, the task was set to keep the pulse in the ANSP area (170 beats / min) at a speed of up to 13.0-13.5 km / h and a pace of up to 110 strokes / min. The change in the recorded parameters of the rower's load on the fourth segment is presented in Table 4. Correction (control actions) from the side of the trainer is shown in Fig. 7. When solving this problem, the athlete covered the distance at a reduced speed of 300 m and 600 m. At these marks, the coach gave a command to the athlete to increase his speed. The athlete made these adjustments. However, the rower at the finish line could not keep the pace. The coach again gave the command at the moment of passing the mark of 600 meters to maintain the pace, which was done.

In the main part of the training, the recovery of the rower between the intervals was individual in time. The athlete rolled out the boat at a low pace and restored his pulse. The recovery lasted 10 to 12 minutes. This time was enough for the athlete to recover and prepare for the next race.

The final stage is a cool down, the athlete spends 20 minutes on the water at low speeds.

The positive effect of using the proposed method lies in the fact that the rower, in the course of the task and on the basis of the trainer's commands, correcting the load, learns to independently feel and control his movements to achieve the required training efficiency.

It is expected that numerous variations and modifications of the implementation of the present invention can be made by those skilled in the art upon studying the above description. Therefore, any variations and modifications fall within the scope of the claims expressed in the claims.
