Description

The power trainer with a terminal belongs to the field of devices and can be used in athletic and medical simulators, for the operational evaluation of an athlete's task and for the provision of information.

There is known a device for tracking and recording exercise, which consists of a motion signal sensor that recognizes user movements and a microprocessor that receives motion signals. The microprocessor is coupled to at least one exercise pattern dispersion carrier for storing motion signal and for creating exercise pattern scattering based on real-time motion received signals. The device includes daily exercise scatter pattern storage daily exercise pattern scattering models, weekly exercise scatter pattern storage medium weekly exercise pattern scattering models, and monthly exercise scatter pattern storage medium monthly exercise pattern scattering models (see U.S. Pat. , A 63 B 21/00).

There is a known abdominal workout exercise management system that allows the trainee to prepare an exact workout menu appropriate to the purpose of the workout, to evaluate his or her physical strength and physique. This is done by automatically gathering data and counting the number of times the exercise is performed and determining the angle of the slope of the simulator bench. The system consists of a terminal with a control element for receiving output signals from the sensors. One of the sensors is used to calculate the number of repetitions of the abdominal muscles exercise, the other to determine the angle of incline of the fitness bench. There is also a recognition part that identifies the trainer and an output element that gives him or her training information. The computer in the system calculates the calories burned from the sensor based on the signals received from the sensor, incorporates the individual's training data, such as physique and physical strength, and displays it (see Japanese Patent No. JP10230022, A 63 B 23/02, 1998).

The disadvantage of this unit, like its analogue, is that it only records exercise performance, but it is difficult for an inexperienced athlete to perform a task accurately and correctly, resulting in injury, but there is no scoring system that evaluates the compliance of the exercise and task immediately .

The object of the invention is to extend the functional capabilities and increase the safety of the workout.

It is an object of the invention that the power trainer with a terminal consisting of a terminal, a personal computer and a sensor trainer comprises a digital processing unit, a heart rate receiver, a contactless receiver, an audible alarm, an indicator and an exercise task assessment unit comprising from the exercise task unit, the mobile phase extraction unit connected to the evaluation unit connected to the indicator, the digital processing unit connected to the inputs to the force trainer with sensors, to the personal computer, to the heart rate receiver, and to the outputs to the an audible alarm, an exercise task node, and a motion phase separation node, the inputs of which are combined with an audible alarm and an indicator consisting of a text indicator, two digital indicators and two graphic inputs. dictators.

The invention is explained in Figure 1, which is a block diagram of a force trainer with a terminal.

Terminal force trainer consists of terminal 1, personal computer 2 and force trainer 3 with sensors 3. wherein terminal 1 consists of a digital processing unit 4, a heart rate monitor 5, a contactless receiver 6, an audible alarm 7, an indicator 8 and an exercise task assessment. a unit 9 comprising an exercise task unit 10, a mobile phase extraction unit 11 connected to an evaluation unit 12. The indicator 8 consists of a text indicator 13, two digital indicators 14, 15, and two graphic indicators 16,17.

PC 2, pre-customized exercise tasks, including number of movement series, number of movements per series, pause between movements, pause between motions, concentric (when muscle contraction defeats resistance), eccentric (when muscle lengthens back to baseline) position) and isometric (when muscular in tension, static) phase durations, amplitude of motion, load magnitude. When the Athlete approaches Terminal 1 and zooms in on the Registration Card, it is automatically recognized. Digital Processing Unit 4, according to the registration code, receives from the computer 2 database a pre-coached exercise task prepared individually by the athlete and enters the task unit via Digital Processing Unit 4 when the Athlete presses the Start button (not shown in the diagram). the terminal 1, after a few seconds for exercise preparation, emits an acoustic signal from the beacon 7 to indicate that the exercise is to commence. The alarm 7 emits an audible signal at the beginning of the eccentric and concentric phase of each movement in the task. It helps the athlete to orientate or maintains the pace of repetition of movements with sufficient precision. As the athlete performs the exercise, the red illuminated bar length of bar 16 of indicator 8 indicates to the athlete the pace at which the movement phase is to be performed. The digital processing unit 4 receives a signal from the force trainer sensor (not shown in the diagram) about the actual received motion and transmits it to the motion phase separation unit 11, which, depending on the motion phase being performed, transmits information about the motion parameters. The green illuminated bar length of column 17 indicates the actual phase of the movement phase. The concentric, isometric, eccentric, and pause times of the performed motion between the movement phases are indicated by the digital indicator 15 and the digital indicator 14 by the number of repetitions of the series performed by the athlete. The athlete can adjust the performance of the training session by seeing the rate of change in the movement phase of the task and the rate of the movement phase he is actually performing. Based on the concentric, isometric, eccentric, and pause times of the movement performed, and the scheduled times, the task performance assessment unit 12 performs workout relevance to the task in a desired scoring system, such as a 10-point rounded integer (1-bad, 10-point - very good) .For evaluation, the signal from each cycle is distinguished by:

- actual amplitude,

- duration of the mobile phases,

- unevenness of motion.

The single-motion amplitude assessment score is calculated using the formula;

A = 10 - Level · (Ai max

Ai. ) - (Au __ „~ Au.) Mm ^{7 v} max min

Here

Level - individual athlete excellence factor Ai _max - measured amplitude of motion,%

Ai _m i _n - measured minimum amplitude of motion,%

Au _max - maximum amplitude of the set amplitude,%

Au _m i _n - minimum amplitude of the set,%

The estimation of the single-motion phase (concentric and eccentric separately) is calculated using the formula:

em J ni-1

Je = 16-Level · i ^ {J ^e jšm J ^e task ^ i ni-1

Here:

Jkjšm - measured amplitude value of the concentric phase of motion,%

Jk _closed - value of the amplitude of the concentric phase of motion,%

If _{iSm is the} measured amplitude value of the eccentric motion phase,%

Je _CLOSE - tasks eccentric motion phase amplitude value% ni - relevant motion phase carried out by measuring the number of points Level - individual athletic prowess estimating factor

After performing N iterations per series, the score is calculated using the following formulas:

Mu is the number of series asked.

The rating is output to the textual indicator 13 immediately after completing a series of exercises, and the summary of the exercise is output immediately after the task scheduled by the trainer. All athlete's exercise data is transferred to a computer 2 database. The rigor of training evaluation is selected based on the athlete's training intensity and training goals, individually determined at the time the task is performed on the computer 2.

Additionally, indicator 8 may optionally indicate power developed during movement (calculated: G = m * g * h / t), work performed during exercise (calculated as A = m * g * h; where m-mass, kg, g- acceleration of free fall in m / s; h-height, m; t-time, s; G-power, W; A-mechanical work, J) or the amplitude of the movement performed, expressed as a percentage.

If the athlete wears a heart rate sensor, the simulator terminal 1 receives the sensor signals via the heart rate receiver 5, displays the pulse value in the text indicator 13, and transmits this information via the communication interface to the computer 2 database. The purpose of the heart pulse receiver 5 is to record and control the pulse rate limits during strength training. If the pulse during exercise exceeds the health-threatening limit, an audible alarm is sounded and a text message 13 terminates the exercise message.

Compared to the prototype, the new set of structural elements motivates the athlete to perform the task correctly, showing the movement of the power trainer in real time, depending on the pre-exercise task, measures the athlete's actual movement of the power trainer in real time; calculates the compliance rating and provides information in the indicator. All of this extends the functionality of the unit and reduces the likelihood of injuries and increases training safety.
