Description

The invention relates to the field of medicine and sports, in particular sports medicine and can be used to determine the predisposition of children to judo on the basis of diagnostics and determination of the morphological status, functional and psychophysiological abilities of children 6-12 years old, used in the practice of doctors of sports medicine and physical therapy culture, sports coaches.

Sports talent is a complex multifaceted phenomenon that is widely considered from methodological, biological, psychological and social positions. Sports giftedness is characterized as a predisposition to a certain type of activity and a higher level of learning / trainability in this form. The sooner this giftedness is revealed, the more effective an individual's sports training can become and the greater the likelihood of his falling into the elite class [1].

The identification of sports talent and giftedness has been in the focus of attention of scientists from different countries for a long time. One of the earliest breakthroughs was made in the USSR by V.M. Zatsiorsky with co-authors [2], this direction is associated with the development of model characteristics of athletes by sports. The analysis of various projects devoted to sports orientation and selection made it possible to develop a method for a comprehensive assessment of the predisposition of children to judo on the basis of testing the morphological status, functional and psychophysiological abilities of the child.

State of the art.

The conducted patent analysis shows that at present, specialists have proposed various methods for assessing the predisposition to practicing a particular sport, however, they are characterized by a narrow focus and diagnosis of only some of the properties of the human body.

There is a known method for predicting the sports abilities of an individual (WO2017003316A1), predicting the sports abilities of an individual, including obtaining fingerprints of both hands, studying their qualitative and quantitative indicators and calculating the delta index for them.

The disadvantage of this method is the assessment of the functional state only on the basis of morphological features that differ in different races and are not confirmed in studies on athletes of different sports.

The method of selection for martial arts training (RU165429U1) allows assessing the speed and accuracy of the subject's motor actions when performing psychophysiological tests on a computer.

Another, similar to the previous one, selection method for playing game kinds of sports (RU2510621C1) allows assessing the correctness of decision-making and the accuracy of the subject's motor actions also based on the performance of a psychophysiological test on a computer.

The method for determining an athlete's predisposition to hockey (RU2405435C1) is based on assessing a complex visual-motor response by presenting a series of 110 light stimuli with a random distribution of green and red colors.

There is also a selection method for practicing cyclic sports (RU2386396C1) based on psychophysiological testing, which consists in presenting a sequence of paired light pulses with a duration of 200 ms, separated by an interpulse interval of 70 ms, repeated at a constant time interval of 1 s. A graph of the dynamics of the threshold interpulse interval is plotted in the coordinates "value of the threshold interpulse interval - testing time".

All of the above methods have a drawback, since they are based only on testing the psychophysiological properties of a person and do not take into account other qualities that affect the effectiveness of future sports activities.

The method for complex functional diagnostics of a person's physical condition (RU2036605C1) uses an integral assessment of a number of human properties. A number of functional indicators are registered and evaluated in points: heart rate, blood pressure, weight-growth index Quetelet, vital indicator, Shtange's test, Skibinsky's index, Rufier's and Serkin's tests while performing them, pulse recovery, speed of visual-motor reaction, spine flexibility, muscle strength of the abdominal press, arms and shoulder girdle, maximum oxygen consumption in the step test according to Astrand - Rimming. The calculation of the index of physical condition - IFS of a person is made according to the formula. The disadvantage of this method is the lack of diagnostics of the morphological status and psychological state, which does not allow to determine the entire structure of functional readiness and predisposition to the sport (judo), to compare with the model normative characteristics of children of a certain age.

The closest to the claimed invention is a method for assessing the predisposition of children to playing football (RU2741210C1), which includes conducting a child psychophysiological, morphological and functional tests and tests for assessing physical fitness, characterized in that measurements are taken in three blocks:

- physical performance is assessed on the basis of the BIP test - a test with a sound signal, in which the initial running speed is 8.5 km / h, which increases every minute by 0.5 km / h, while the level of the test subject's fitness is assessed by the number of distances covered before it does not fit into the requirements of sound signals, and with a value of the maximum achieved level of at least: 3 levels for girls and boys 6 years old, 4 levels for girls 7 years old, 5 levels for boys 7 years old and girls 8 years old, 6 levels for boys 8 years old and girls 9-10 years old, 7 levels for boys 9 years old and girls 11-12 years old, 8 levels for boys 10-11 years old, 9 levels for boys 12 years old are estimated at three points;

then all the received points are summed up, receiving the level of the integral assessment, at the level of the integral assessment of at least 11 points, it is determined that the child has a predisposition to football.

The disadvantages of this method are the lack of diagnostics of the index of the ratio of the strength to mass, speed-strength physical fitness, flexibility, the use of model normative characteristics for assessing the vital indicator, the type of skeleton, the assessment of the type of muscle fibers, the assessment of the body type intended for the sport of football, which does not allow to determine the entire structure of functional readiness and predisposition to the kind of sport (judo).

The objective of the invention is to create a method for assessing the predisposition of children to judo.

Moreover, what is new is that:

- made the choice of the maximum number of indicators and the most informative techniques in the proposed method in accordance with the psychophysiological, functional, morphological criteria for the sport (judo);

- criteria for assessing each indicator have been developed in accordance with the requirements of the sport (judo), which makes it possible to increase the level of diagnostic reliability;

- the use of an integral assessment when processing the maximum number of indicators with psychophysiological, functional, morphological criteria for a sport (judo) to determine the predisposition of children 6-12 years old to judo;

The task is achieved by the fact that the method for assessing the predisposition of children 6-12 years old to judo training includes 3 blocks of tests: psychophysiological, morpho-functional and tests for assessing physical fitness.

The description of the essence of the invention is as follows

Psychophysiological testing of children is carried out using the AIC “Sports orientation of children and adolescents” (AIC) [3]. The instructor turns on the APC console and launches the corresponding computer program on the computer, makes the program settings, enters the gender, age, surname, name and patronymic of the tested person into the program, starts a new study. The APC console device is a specialized microcomputer, the program of which is stored in non-volatile memory. The principle of operation is based on recording the time spent on the response upon presentation of a light and / or sound stimulus. The data from the control panel are transferred to the computer program, the results are displayed on the computer display and are stored in the nonvolatile memory of the computer. The subject is instructed. He performs tests, guided by the instructions displayed on the computer display, that is, he presses the "work with the test" button when a stimulus is presented in the corresponding tests. In this APC, the subject undergoes the following tests:

1) Evaluation of a simple visual-motor reaction is carried out by presenting a series of 5 light stimuli of red color. Upon presentation of a red light stimulus, the subject presses the "Work with the test" button, then the reaction time to each red stimulus is recorded and the average reaction time is determined, and if the average reaction time is less than that shown in Table 1, the integral assessment (SR) is increased by one point (initial CP state is zero).

2) Evaluation of a complex visual-motor reaction (choice reaction) is carried out by presenting a series of 10 light stimuli with a random distribution of green and red colors. Upon presentation of a red light stimulus, the subject presses the "Work with test" button; upon presentation of a green stimulus, the subject does not press the "Work with test" button. The first red stimulus is considered training, then the response time to each red stimulus is recorded, the average response time is determined, and if the average response time is less than that shown in Table 1, the integral assessment (SR) is increased by one point.

3) Assessment of the type of temperament is carried out using the test "determination of an individual unit of time." The test is based on memorizing simultaneously light and sound stimuli lasting from 2000 to 6000 ms, appearing in random order (16 intervals in total). The subject reproduces the intervals filled with the stimulus by pressing the "Work with test" button on the remote control. AIC calculates the duration of an individual unit of time if it lies in the range from 0.79 to 0.94 conv. units inclusive (sanguine temperament) in accordance with Table 1, then the integral assessment (CP) is increased by one point.

4) Evaluation of work efficiency, degree of training, mental stability (endurance) is carried out using the Schulte test. When passing the test, five square tables are sequentially displayed on the computer display, filled in random order with numbers from 1 to 25. The subject needs to find and click on all the numbers of the square table in order from 1 to 25. This should be done as soon as possible and without errors for all five square tables from the test. Until all the numbers in the table have been traversed with mouse clicks, the new table is not presented. The computer program calculates indicators of work efficiency, the degree of training, mental stability (endurance). If the value of work efficiency is lower than that presented in table 1, the integral assessment (CP) is increased by two points. When the value of the degree of workability is below 0.95 conv. units in accordance with table 1, increase the integral assessment (CP) by one point. When the value of mental stability (endurance) is below 1.05 conv. units in accordance with table 1, increase the integral assessment (CP) by one point.

The morpho-functional block of tests includes: assessment of growth, vital signs, determination of the type of skeleton, type of muscle fibers, body type, index of the ratio of the strength to mass. In this block, the subject passes the following tests:

5) Assessment of growth is carried out after measuring the height with a stadiometer. The height of the subject is determined on the scale of the stadiometer, with the growth not exceeding that presented in table 2, the integral assessment (CP) is increased by one point.

Table 2 - Due numerical values of growth

Test number Test (name) Indicator name, unit of measure Score, points Age, years The proper numeric value of the indicator girls boys 5 Growth assessment height, cm 1 6 no more than 120 not more than 121 7 no more than 126 no more than 127 eight no more than 132 no more than 133 nine no more than 139 no more than 139 ten no more than 145 no more than 144 eleven no more than 149 no more than 148 12 no more than 154 no more than 155

6) Assessment of vital signs (LI) is carried out as follows. Using, for example, a portable MicroLoop Carefusion spirometer, vital lung capacity (VC) is measured in milliliters. The balance is used to measure the weight of the subject in kg (fMassa). Calculate the specific VC (VC) in ml / kg according to the formula: VC = VC / fMassa. Further, the VC is calculated as the ratio of VC to the proper specific VC (VC) according to the formula: VC = VC / VC, where VC = 67.5 ml / kg for males or VC = 57.5 ml / kg for females. If the obtained value of ZhP is more than 0.85 conv. units, then increase the integral assessment (SR) by one point.

7) Assessment of the type of skeleton (TS) is carried out as follows. The height of the subject in cm (fHeight) is determined on the scale of the stadiometer. With the help of a centimeter measuring tape, the length of the leg (fFoot), the length of the arm (fHand), and the girth of the wrist (fOxvatZ) are determined in cm. The index characterizing the type of skeleton is calculated by the formula: TC = 100⋅fOxvatZ / (1.28-0.072⋅fFoot + 0.03⋅fHeight + 0.256⋅fHand). If the resulting value of the vehicle is greater than or equal to 120 conv. units, then increase the integral assessment (SR) by one point.

8) Assessment of muscle fiber type (MF) is carried out as follows. The wrist dynamometer measures the compressive force of the right (fRHand) and left (fLHand) hands in kg. The grip strength of the strongest hand (fMaxHand) is determined. To determine the endurance of the strongest hand, reduce the grip force of the wrist dynamometer so that it is 50% of the maximum strength of the strongest hand. The stopwatch determines the time in seconds during which the subject will be able to hold such an effort (fHand50). The scale measures the body weight in kg (fMassa). The relative strength index (IS) is calculated by the formula: IS = 100⋅fMaxHand / fMassa. The type of muscle fibers is determined by the formula: MV = fHand50 / IS. If the obtained value of MV is less than or equal to 2 conv. units, then increase the integral assessment (SR) by one point.

9) Assessment of body type (TT) is carried out as follows. The height of the subject in cm (fHeight) is determined on the scale of the stadiometer. The scale measures the body weight in kg (fMassa). With the help of a measuring tape, the subject is measured in cm at rest, the circumference of the chest (fOxvat). The PINIER index is calculated by the formula: TT = fHeight-fMassa-fOxvat. If the obtained value of TT is less than or equal to 30 srvc. units, then increase the integral assessment (SR) by one point.

10) Evaluation of the index of the ratio of the strength to mass (CM) is carried out as follows. The scale measures the body weight in kg (fMassa). The deadlift is measured in kg (fTyaga) with the deadlift. The index of the ratio of the strength to mass is calculated by the formula: CM = fTyaga / fMassa. If the obtained value of the CM is more than 2.4 srvc. units (for boys) or more 2 conv. units (for girls), then the integral assessment (CP) is increased by one point.

The block of tests for assessing physical fitness includes: measurement of speed, coordination, speed-strength abilities, flexibility, endurance assessment (BIP test). During the test, the subject should not experience general malaise, take drugs that affect the heart, suffer from acute infectious diseases and ailments of the musculoskeletal system. Before testing, the subject performs an individual or general warm-up under the guidance of an instructor, teacher (trainer-teacher) or independently. The subject's clothing and footwear are sports. In this block, the subject passes the following tests:

11) Evaluation of speed abilities (30 meters running) is carried out as follows. The test is carried out on any level surface with a hard surface that provides good grip on the shoe. At a distance of 30 m, marking cones are set or two parallel lines are drawn - "Start" and "Finish". The tested person, without stepping on the starting line, takes a high start position. At the command "March!" (with the simultaneous activation of the stopwatch) the tested person runs at maximum speed to the finish line, overcoming this segment of the distance without touching the finish line with his hand. The stopwatch is stopped at the moment the tested person crosses the “Finish” line. Running time is determined using a stopwatch. If the value of the running time is less than that presented in Table 3, the integral assessment (CP) is increased by one point.

12) Evaluation of coordination abilities (shuttle run 3x10 m) is carried out as follows. The test is carried out on any level surface with a hard surface that provides good grip on the shoe. At a distance of 10 m, marking cones are installed or two parallel lines are drawn - "Start" and "Finish". The tested person, without stepping on the starting line, takes a high start position. At the command "March!" (with the simultaneous switching on of the stopwatch) the tested person runs at maximum speed to the finish line, touches the line with his hand, returns to the start line, touches it with his hand and overcomes the last segment without touching the finish line with his hand. The stopwatch is stopped at the moment the tested person crosses the “Finish” line. Running time is determined using a stopwatch. If the value of the running time is less than that presented in Table 3, the integral assessment (CP) is increased by one point.

13) Evaluation of speed-strength abilities (long jump from the spot) is carried out as follows. The test is carried out on any level surface with a hard surface that provides good grip on the shoe. The subject needs to stand in this position: legs apart shoulder-width apart, feet in a parallel position, and socks - in front of the starting line. You need to jump by simultaneously lifting both legs from the surface, you can also wave your arms. Having landed, the subject straightens up, takes 2 steps forward, and only after that leaves the place of his jump. The length of the jump is measured along the perpendicular line from the start line to the nearest point of contact with the subject's body surface. If the value of the standing jump length is greater than that presented in Table 3, the integral assessment (CP) is increased by two points.

14) Evaluation of flexibility (bending forward from a sitting position) is carried out as follows. The necessary markings (temporary or permanent) are applied on the floor: a horizontal line (60-70 cm long) and a vertical line dividing the horizontal in half. At the intersection of the lines there is a mark "0", then along the vertical there is a marking every 0.5 cm: up - up to 25-30 cm, down - up to 10-15 cm. Results above the zero mark are counted with a "+" sign, and below zero marks - with a - "-" sign. Before performing the exercise, the subject sits on the floor so that the heels are at the horizontal line, but not touching it. The distance between the heels is 20-30 cm. The vertical line should be in the middle between the heels. When performing an incline, do not bend your knees. At the command "Start!" the subject makes three warm-up inclinations, touching the floor in front of him with his fingers; the fourth slope is valid. The result can be positive (with a “+” sign), if the fingertips are behind the zero mark, and negative (with a “-” sign), if the fingers did not reach it. The measurement is made with an accuracy of 0.5 cm. If the length of the forward bend from the sitting position is greater than that shown in Table 3, the integral score (CP) is increased by one point.

15) Assessment of physical performance (BIP test - test with a sound signal) is carried out as follows. The test involves running between two marks at a distance of 20 m from each other in accordance with the sound signals. A variant is possible when two parallel lines "Start" and "Finish" are drawn at a distance of 20 m. The subject, without stepping on the starting line, takes a high start position. The subject runs to the finish line, crosses the line with his foot, returns to the start line, crosses it with his foot and continues to cover the segments of the distance. The time between recorded beeps decreases with every minute (level). The initial running speed is 8.5 km / h, every minute it increases by 0.5 km / h (the beep sounds more often). The level of the test subject's preparedness is assessed by the number of distance segments covered before it does not fit into the requirements of the audio signals recorded on the carrier. Equipment: a flat, clean, non-sticky surface with a size of at least 30x2 m with a hard coating that provides good adhesion to shoes, a CD-R disc or a USB flash drive with sound recording, a sound reproduction device with a power sufficient for working in outdoor conditions, a pencil, a blank for recording the test results presented in Table 4. As a result of passing the BIP test, physical performance is determined by the number of the achieved level. If the value of the maximum achieved level is not less than that presented in Table 3, the integral assessment (CP) is increased by three points.

Thus, all the indicators obtained are evaluated in accordance with the proper numerical values of the indicators, the integral assessment of the SR is obtained on the basis of the sum of the indicators' estimates. At the level of the integral assessment of SR of at least 13 points, the child is recommended to practice judo.

The effectiveness of the proposed method lies in a unique set of diagnostic tests for each of the blocks, as well as the ability to conduct analysis, comparing the data obtained with the standard and model characteristics, thereby making a conclusion on each of the diagnosed characteristics. The possibility of obtaining an integral assessment gives sports medicine doctors, coaches, children (as future athletes) and their parents an indispensable tool for diagnosing psychophysiological, functional abilities of a child and morphological status for determining a predisposition to judo. It is advisable to use the method at specialized sports training bases, medical and physical dispensaries, sports clubs, children's and youth sports schools, secondary schools.

An example of implementation of the invention is as follows

Example 1. Subject Artem A., 7.5 years old. A psychophysiological study was carried out using the AIC “Sports orientation of children and adolescents” [3] including the following tests:

1) Evaluation of a simple visual-motor reaction is carried out by presenting a series of 5 light stimuli of red color.

2) Evaluation of a complex visual-motor reaction (choice reaction) is carried out by presenting a series of 10 light stimuli with a random distribution of green and red colors.

3) Assessment of the type of temperament is carried out using the test "determination of an individual unit of time."

4) Evaluation of work efficiency, degree of training, mental stability (endurance) is carried out using the Schulte test.

At the end of testing, the display showed the calculated parameters: the average time of a simple visual-motor reaction, the average reaction time of choice, the results of the Schulte test (work efficiency, degree of training, mental stability (endurance)). The calculated parameters obtained and the assessment of the results correlated with the criteria of Table 1 are presented in Table 5. Next, the subject passed the morpho-functional block of tests and the block of tests for assessing physical fitness:

5) Assessment of growth was carried out after measuring the height with a stadiometer. The height of the subject was determined on the scale of the stadiometer. The obtained value and the assessment of the result correlated with the criteria of Table 2 are presented in Table 5.

6) Vital signs were assessed using a MicroLoop Carefusion portable spirometer and a balance. The vital capacity of the lungs was measured in milliliters (VC = 2390 ml). The weight of the subject was measured in kg (fMassa = 29 kg). The specific VC (VC) was calculated in ml / kg according to the formula: VC = VC / fMassa = 2390/29 = 82.4 ml / kg. Further, the VC was calculated as the ratio of VC to the proper specific VC (VOC) according to the formula: VC = VC / VOC = 82.4 / 67.5 = 1.22 conv. units, where ACORN = 67.5 ml / kg for males. Since the obtained value of ZhP is more than 0.85 conv. units, then the assessment of the result is equal to one point. The obtained value and the evaluation of the result are presented in table 5.

7) Assessment of the type of skeleton (TS) was carried out as follows. The height of the subject in cm (fHeight = 128 cm) was determined using the height meter scale. With the help of a centimeter measuring tape, the length of the leg (fFoot = 73 cm), the length of the arm (fHand = 54 cm), and the girth of the wrist (fOxvatZ = 14 cm) were determined in cm. Next, the indicator characterizing the type of skeleton was calculated using the formula: ТС = 100⋅fOxvatZ / (1.28-0.072⋅fFoot + 0.03⋅fHeight + 0.256⋅fHand) = 100⋅14 / (1.28-0.072⋅73 + 0, 03⋅128 + 0.256⋅54) = 102 arb. units. Since the obtained value of the vehicle is less than 120 conv. units, then the estimate of the result is zero. The obtained value and the evaluation of the result are presented in table 5.

8) Assessment of muscle fiber type (MF) was carried out as follows. Using a wrist dynamometer, the compressive force of the right (fRHand = 13 kg) and left (fLHand = 12 kg) hands was measured in kg. The compressive force of the strongest hand was determined (fMaxHand = 13 kg). To determine the endurance of the strongest hand, the compression force of the wrist dynamometer was reduced so that it was 50% of the maximum strength of the strongest hand, that is, up to 6.5 kg. The stopwatch was used to determine the time in seconds during which the subject held such an effort (fHand50 = 19 seconds). The body weight was measured in kg using a balance (fMassa = 29 kg). The relative strength index (IS) was calculated using the formula: IS = 100⋅fMaxHand / fMassa = 100⋅13 / 29 = 44.83 arb. units. Determined the type of muscle fibers by the formula: MV = fHand50 / IS = 19 / 44.83 = 0.42 conv. units. Since the obtained value of MV is less than 2 conv. units, then the assessment of the result is equal to one point. The obtained value and the evaluation of the result are presented in table 5.

9) Assessment of body type (TT) was carried out as follows. The height of the subject in cm (fHeight = 128 cm) was determined using the height meter scale. The balance was used to measure body weight in kg (fMassa = 29 kg). With the help of a centimeter measuring tape, the subject was measured in cm in a calm state, the circumference of the chest (fOxvat = 65 cm). The PINIER index was calculated by the formula: TT = fHeight-fMassa-fOxvat = 128-29-65 = 34 arb. units. Since the obtained value of TT is more than 30 conv. units, then the estimate of the result is zero. The obtained value and the evaluation of the result are presented in table 5.

10) Evaluation of the index of the ratio of the strength to mass (CM) was carried out as follows. The balance was used to measure body weight in kg (fMassa = 29 kg). Deadlift in kg (fTyaga = 45 kg) was measured using a deadlift dynamometer. The index of the ratio of the strength to the mass was calculated by the formula: СМ = fTyaga / fMassa = 1.55 conventional units. Since the obtained value of CM is less than 2.4 srvc. units, then the estimate of the result is zero. The obtained value and the evaluation of the result are presented in table 5.

11) Evaluation of speed abilities (running at 30 m) was carried out as follows. The test was carried out on a level surface with a hard surface that provides good grip on the shoes. At a distance of 30 m, two parallel lines were drawn - "Start" and "Finish". The subject, without stepping on the starting line, took the high start position. At the command "March!" (with the simultaneous switching on of the stopwatch) the subject ran at maximum speed to the finish line, overcoming this segment of the distance without touching the finish line with his hand. The stopwatch was stopped at the moment the subjects crossed the “Finish” line. The running time was determined using a stopwatch. The obtained value and the assessment of the result correlated with the criteria of Table 3 are presented in Table 5.

12) Evaluation of coordination abilities (shuttle run 3x10 m) was carried out as follows. The test was carried out on a level surface with a hard surface that provides good grip on the shoes. At a distance of 10 m, two parallel lines were drawn - "Start" and "Finish". The subject, without stepping on the starting line, took the high start position. At the command "March!" (with the simultaneous start of the stopwatch) the subject ran at maximum speed to the finish line, touched the line with his hand, returned to the start line, touched it with his hand and overcame the last segment without touching the finish line with his hand. The stopwatch was stopped at the moment the subjects crossed the “Finish” line. The running time was determined using a stopwatch. The obtained value and the assessment of the result correlated with the criteria of Table 3 are presented in Table 5.

13) Evaluation of speed-strength abilities (long jump from the spot) was carried out as follows. The test was carried out on a level surface with a hard surface that provides good grip on the shoes. The subject stood in the starting position: the legs are shoulder-width apart, the feet are in a parallel position, and the toes are in front of the starting line. The jump was performed with the simultaneous separation of both legs from the surface with a wave of the arms. Having landed, the subject straightened up, took 2 steps forward and then left the place of his jump. The jump length was measured along the perpendicular line from the starting line to the nearest point of contact with the subject's body surface. The obtained value and the assessment of the result, correlated with the criteria of Table 3, are presented in Table 5.

14) Evaluation of flexibility (bending forward from a sitting position) was carried out as follows. The necessary markings were applied on the floor: a horizontal line (60-70 cm long) and a vertical line dividing the horizontal line in half. At the intersection of the lines there is a mark "0", then along the vertical there is a marking every 0.5 cm: up - up to 25-30 cm, down - up to 10-15 cm. Results above the zero mark are counted with a "+" sign, and below zero marks - with a - "-" sign. Before performing the exercise, the subject sat on the floor so that the heels were at the horizontal line, but did not touch it. The distance between the heels is 20-30 cm. The vertical line was in the middle between the heels. When performing an incline, the subject did not bend his knees. At the command "Start!" the subject made three warm-up bends, touching the floor in front of him with his fingers; the fourth slope is valid. The result of measuring flexibility (bending forward from a sitting position) was +9.5 cm.The obtained value and the assessment of the result, correlated with the criteria of Table 3, are presented in Table 5.

15) Assessment of physical performance (BIP test - test with a sound signal) was carried out as follows. The test consisted of running between two marks spaced 20 m from each other in accordance with the given sound signals. At a distance of 20 m, two parallel lines "Start" and "Finish" were drawn. The subject, without stepping on the starting line, took the high start position. The subject ran to the finish line, crossed the line with his foot, returned to the start line, crossed it with his foot, and continued to cover sections of the distance. The time between recorded beeps decreased with every minute (level). The initial running speed was 8.5 km / h, every minute it increased by 0.5 km / h (the beep sounded more often). The subject reached level 6 in accordance with table 4. The obtained value and the assessment of the result, correlated with the criteria of table 3, are presented in table 5.

The time spent on testing was about 30 minutes.

Since the integral assessment based on the sum of assessments of HR indicators is 13 points, which is not less than 13 points, the child is recommended to practice judo.

The technical result consists in providing the possibility of diagnosing a child's body, assessing various aspects of development and condition, determining a predisposition to successful judo lessons.

Thus, the method for assessing the predisposition of children to judo exercises has new properties that determine the receipt of a positive effect.
