Abstract

FIELD: medicine.

SUBSTANCE: method involves testing basic qualities during prolonged period like swiftness, strength, endurance and speed-and-force characteristics of pupils. The obtained results are compared with reference values. Test value deviations from the reference values are detected in age groups. Condition abilities are evaluated. The condition abilities are evaluated using integral indices of physical fitness. Normal and predisease or pathologic states are to be determined. Physical training lessons influence is estimated under natural training lesson conditions using physical condition index and hemodynamic components of cardiovascular system with orthostatic tests for determining adaptive organism reserves being applied. Low physical training capacity level with 55-95 points being detected and physical state level being equal to 0.375-0.525, hemodynamic changes of arterial blood pressure being greater than 20% when compared to norm, heart beat rate increment and load index deviation being greater than 20%, aerobic-anaerobic training of bioenergetics is to be increased with additional acyclic training exercises inclusion. Physical loading intensity is selected within 60-75% limits when compared to maximum with regularity in week cycle not less than 3 times a week. Motor mode is added with static force loading which intensity is set within 60-70% limits when compared to maximum. Training types are corrected with physical development indices taken into account estimated by using somatometric and physiometric indices of age-specific development. If at least one value of the indices violates the limits of statistical mean control values, physical training exercises for restoring body build proportionality are to be included into training. Prescribed exercises dose is increased if physical fitness index obtained earlier before training exercises type correction is not lower than the statistical mean control values in age-specific pupil group.

EFFECT: high accuracy of estimates.

Description

The invention relates to valeology and can find application for assessing and correcting the physical development of schoolchildren, in particular students from grades 1 through 11.

The invention will solve the problem of adverse environmental effects on the health of students.

There is a method of expert assessment of the physical development of adolescents of military age, which consists in assessing the physical development of adolescents of military age (see RF patent No. 2145793, M. Cl. A 61 B 5/103, publ. 02.27.2000, "Method of expert assessment of physical development of adolescents of military age "). The method allows to differentiate different states of physical development of adolescents of military age and to distinguish among them groups of people with various combinations of body mass index (BMI) and relative body fat mass (BMI) parameters, to evaluate the physical health of adolescents by the ratio of parameters.

The known method does not allow to study in the complex the main parameters of the dynamics of the formation of qualities, properties and abilities of children in their ontogenetic development and preparedness, to assess the dynamics of fluctuations in the components of physical fitness of students of the same age and gender over a long period of time.

There is a method of assessing the physical condition of a person, including a set of control tests that determine the speed, strength, endurance and speed-power qualities, comparing the results with standard indicators, determining the basis for assessing the physical condition (see the laid out application No. 200111193 for the invention, A 61 B 10 / 00, publ. 07/10/2003, “Method for assessing the physical condition of a person”), selected by the applicant as a prototype.

In the known method, after each test, control of the heart rate (HR) is carried out and the next test is carried out at a heart rate close to normal.

According to test and normative age indicators selected from the table, an individual profile of the participant’s condition is built.

The disadvantages of this method are:

- not high accuracy in assessing the parameters of the dynamics of the formation of qualities, properties and abilities of children in their ontogenetic development and preparedness;

- the complexity of assessing the dynamics of fluctuations in the components of physical fitness of students of the same age and gender in the ontogenesis of the physical development of children, adolescents, boys and girls, taking into account the results of their physical fitness and physical condition;

- the difficulty of adjusting the training and competitive loads of children, adolescents, boys and girls, taking into account their physiological characteristics.

The technical result of the invention is:

- improving the accuracy of the assessment in the ontogenesis of the physical development of children, adolescents, boys and girls, taking into account the results of their physical fitness and physical condition;

- simplification of the assessment of the dynamics of fluctuations in the components of physical fitness of students of the same age and gender in the ontogenesis of the physical development of children, adolescents, boys and girls, taking into account the results of their physical fitness and physical condition;

- the ability to adjust and dispense training and competitive loads of children, adolescents, boys and girls, taking into account their physical fitness, physical condition and hemodynamics;

- Efficiency of adjusting the dosage of training and competitive loads.

The specified technical result is achieved by the fact that in the method of preserving the health of students, including testing the basic qualities: speed, strength, endurance and speed-power qualities of students over a long period, comparing the results with normative indicators, identifying deviations of test indicators in age groups from standard and assessing the conditioning abilities of students, according to the invention, evaluating conditioning abilities by an integral indicator of physical fitness, students are diagnosed with a state of norm or pre-illness or pathology, they additionally evaluate the impact of training sessions in a natural training process according to the index of physical condition and indicators of hemodynamic components of the cardiovascular system using orthostatic tests determining adaptive reserves of the body, with a low level of physical fitness equal to 55-95 points, and the value of the index of physical condition equal to 0.375-0.525, a change in hemodynamics of blood pressure by more than 20% compared With a norm, an increase in heart rate and a deviation in the IN value by more than 20%, aerobic-anaerobic endurance training is enhanced by the additional inclusion of cyclic exercises, while the intensity of physical activity is chosen within 60-75% of the maximum with regularity in the weekly cycle of at least 3 once a week, the motor mode is supplemented with static power loads, the intensity of which is set 60-70% of the maximum.

In addition, to adjust aerobic-anaerobic training, somatoscopic, somatometric and physiometric indicators are evaluated, and if at least one of these indicators is outside the control average statistical standards, then physical exercises aimed at restoring the proportionality of physique are additionally included in the training.

As somatoscopic indicators, indicators of the foot and posture are selected.

As somatometric indicators, indicators of growth, weight, the ratio of weight to height, vital capacity of the lungs, the ratio of weight to vital capacity of the lungs are selected.

As physiometric indicators, dynamometer values of the right hand, dynamometry of the left hand, dead force, the ratio of dead force to body weight, and dynamic force are selected.

At the same time, the integral indicator of physical fitness contains parameters of age, body weight, blood pressure, heart rate at rest, flexibility of the spinal column, speed, dynamic strength, speed endurance, speed-strength endurance, general stamina, and pulse recovery.

The physical state indicator contains parameters of body weight, blood pressure (BP), resting heart rate, age and height.

As characteristics of the hemodynamic components, indicators of minute and stroke blood volume, heart rate, and the IN index in the supine and orthoprobe samples are selected.

The values of the indicators of physical development are evaluated according to three-level scales of average values of somatoscopic, somatometric and physiometric indicators.

The value of the physical fitness indicator is evaluated in points on a five-level scale of the level of physical fitness.

Evaluation of conditioning abilities by an integrated indicator of physical fitness, including indicators of age, body weight, blood pressure, resting heart rate, spinal column flexibility, speed, dynamic strength, speed endurance, speed-strength endurance, general endurance, and pulse recovery, improves the accuracy of the assessment since it makes it possible to study the dynamics of the formation of qualities, properties and abilities of children in their ontogenetic development and preparedness, the dynamics of fluctuations Nia components of physical fitness of students of the same age and gender.

The integral indicator of physical fitness reflects the uneven development of the complex of physical qualities in ontogenesis in schoolchildren and allows you to conduct indicative (stage) control over the formation of vital functions and components of physical development in children.

To calculate the integral indicator, testing is carried out on all its parameters, the results obtained are compared with control normative indicators and the state of the norm or pre-illness or pathology is revealed in the students.

The deviation from the standard is determined as a percentage; for this, the initial indicator (for example, at the beginning of the year), taken as 100%, is compared with the final (end of the year). Qualitative indicators for determining the shift are presented in quantitative assessments of the generally accepted five-level scale, reflecting the level of physical fitness.

Evaluation of the results allows you to identify the following conditions in students:

- norms if the integral indicator of physical fitness is equal to or higher than 96 points;

- pre-illness, if the integral indicator of physical fitness was equal to or higher than 55 points;

- pathology, if the integral indicator of physical fitness was below 55 points.

The integral indicator of physical fitness can be graphically reflected in the form of a graph of the student’s physical fitness profile based on age norms of motor tests, which makes it possible to quickly track the levels of individual properties, qualities and abilities of the student with the goal of their current correction during systematic physical education.

However, for the current correction of the type and dosage of training exercises, a periodic operational assessment of the impact of physical exercises (UFS) is necessary in a natural training process.

The index of physical condition (IFS) allows you to quickly assess the reserve capacity of the body involved, since it includes parameters of the pulse rate at rest, systolic pressure, diastolic pressure, age of the subject, body weight, height, characterizing the possibilities of physical performance. The value of the index of physical condition (IFS) is calculated by the formula and to determine the individual level of the physical condition of the student, it is compared with the values reflected in the five-point scale shown in table 1.

Table 1 UFS - level of physical condition Value Range (IFS) 1. Low Less than 0.375 2. Below average 0.376-0.525 3. Medium 0.526-0.675 4. Above average 0.676-0.825 5. High 0.826 and higher

Insufficient motor activity, as well as excessive physical activity, leads to pre-painful and painful conditions in connection with individual adaptive changes in hemodynamics.

An additional step-by-step assessment of the impact of training sessions on the indicators of the hemodynamic components of the cardiovascular system using orthostatic tests allows us to identify individual adaptive changes in hemodynamics and identify general patterns taking into account the type of blood circulation and its regulation, which will increase the accuracy of the assessment in the ontogenesis of the physical development of children, adolescents, youths and girls, taking into account their physical fitness and physical condition.

The choice of indicators of minute blood volume (MO) and stroke volume (UO), heart rate (HR), and IN in the supine and orthoprobe samples as hemodynamic components of the cardiovascular system using orthostatic samples will allow us to judge the state of neurohumoral regulation of the system blood circulation of the child, to quickly highlight the features of the circulatory system and its regulation.

The “IN” indicator indicates an objective characteristic in assessing myocardial tension of the heart muscle, which is widely used in diagnostics and treatment, as well as its use in research on biology, medicine, space medicine, physical education and sports (P.M. Baevsky, 1979).

Hemodynamic indicators at rest (lying down) are characterized as the most stable due to the fact that the arteries and veins are located in this case at approximately the level of the heart and gravity acts uniformly on them, they provide an objective assessment of the regulation of cardiac activity at different phases of adaptation, tension and overvoltage , preparedness and condition of students with overwork and overtraining.

To calculate the indicators of hemodynamic components using orthostatic samples, testing is carried out and the results obtained are compared with standard indicators.

Disadaptive indicators in this case, as studies have shown when conducting an orthostatic test, it is necessary to consider:

- A sharp increase in heart rate (heart rate);

- A sharp increase or decrease in SBP (more than 20%);

- growth of the Hiter index with orthostasis;

- IOC growth with a simultaneous increase in heart rate and CSS;

- a sharp increase in the ratio of the phases of the pre-exile and exile FP / FI;

- significant changes in performance when lying and orthoprobe.

Important indicators of heart performance are IOC, minute and stroke volumes of blood (MO and UO). When studying these indicators in lying and orthoprobe tests, it turned out that students from younger to older age showed an increase in SV and IOC, and heart rate in a lying test decreased. There was an excess of the value of UO and IOC in boys compared with girls aged 9-12 years and boys and girls 16-17 years old.

Such reactions were noted in the older groups of the subjects, which was associated with their insufficiently active motor mode. It was found that a decrease in the indicated parameters is comparable with an increase in vascular compliance and subsequent resistance to orthostasis.

Physical activity provides aerobization and leads to a decrease in compliance by increasing muscle mass around the veins.

Strengthening aerobic-anaerobic endurance training by the additional inclusion of cyclic exercises with a low level of physical fitness equal to 55-95 points, and a value of the physical condition index equal to 0.375-0.525, a change in blood hemodynamics of more than 20% compared to normal, increase in heart rate and deviation an IN value of more than 20 provides aerobization and leads to a decrease in compliance by increasing muscle mass around the veins.

The choice of the intensity of physical activity within 60-75% of the maximum with regularity in the weekly cycle at least 3 times a week allows you to adjust the training and competitive loads of children, adolescents, boys and girls, taking into account individual physical fitness and physical condition. Supplementing the motor regime with static power loads, the intensity of which is set to 60-70% of the maximum, allows to dose training and competitive loads taking into account the individual physical condition and hemodynamics. At the same time, within the limits of static loads, it is possible to regulate the increase in intramuscular pressure by 50 mm Hg.

Correction of the type of training, carried out taking into account indicators of physical development, assessed by a number of somatoscopic, somatometric and physiometric indicators, allows you to influence the physical development of the student even if there is a deviation of individual parameters from the standards, by changing, if necessary, the type of training and / or dosing of training exercises and competitive loads.

Somatoscopic indicators of the foot and posture will allow you to quickly analyze the dynamics of the norm and deviations from the norm of signs of the foot, posture.

Somatometric indicators of growth, weight, ratio of weight to height, vital lung capacity, ratio of weight to vital lung capacity will allow you to analyze the dynamics of the norm and deviations from the norm of signs of growth, body weight, lung capacity.

Physiometric indicators of dynamometry of the right hand, dynamometry of the left hand, dead force, the ratio of dead force to body weight, dynamic force will allow you to control the dynamics of the norm and deviations from it signs of dynamometry of the right and left hands, dead force, dynamic force.

Taking into account, along with an integral indicator of physical fitness, an index of the physical condition and indicators of hemodynamic components, as well as indicators of physical development, assessed by a number of somatoscopic, somatometric and physiometric indicators, it allows more accurately reflecting the age-morphological levels and the degree of proportionality of development, comprehensively evaluating conditioning abilities, substantiating individual rational motor mode, adjust and dose training, competitively atelnye load of children, teenagers, young men and women with regard to their physical fitness, physical condition and hemodynamics.

The values of indicators of physical development, evaluated by somatoscopic, somatometric and physiometric characteristics of physical development, are calculated in points on three-level scales of average statistical values and presented in the form of a graph of the student’s anthropometric profile using age norms of morphometric indicators.

Figure 1 shows a graph of the profile of physical fitness, built as a result of the assessment of indicators of physical fitness of the student in comparison with standard indicators.

Figure 2 shows a graph of the profile of the physical fitness of the student K-on in the process of correction and control of his qualities and abilities.

The proposed method is as follows.

Preliminarily, the test results are compared with normative indicators, which were obtained by examining the physical fitness of 5379 students, due to health status assigned to the main medical group, aged 6 to 17 years, different sexes (schools No. 25, 35, 78 and 138 of Chelyabinsk ) in the period from 1994-2004 school years.

Control assessment testing included the following exercises:

- raising the torso from a supine position;

- shuttle run 4 × 9 m;

long jump from a place;

- leaning forward from a sitting position.

The results were mathematically processed on a computer and formed the basis for assessing conditioning abilities by the integrated indicator of physical fitness of the proposed method.

Tables 2 and 3 show the physical fitness parameters of boys and girls, respectively (schools in the city of Chelyabinsk), measured during 1994-2004. Table 4 shows the age norms of motor tests, on the basis of which the conditioning abilities of boys and girls were evaluated.

The integral indicator was estimated based on the following parameters:

- age: each year of life is estimated at 1 point;

- body weight corresponding to the norm in its age group is estimated at 30 points, the weight norm is calculated by the formula: P = D-108 at D = 155-165; P = D-106 at D = 165-175; P = D-110 at D = 175 and above; where D is the growth of the child; when exceeding the norm of 2.5 kg (with a decrease in the norm of 2.5 kg), subtract 5 points from the total;

- blood pressure (BP) is normally estimated at 30 points, with a deviation from the norm of 5 mm Hg. the values of DM or DD are subtracted from the norm of 5 points; normative indicators of blood pressure for children are determined according to the table of A.P. Khripkov;

- the pulse is at rest, its assessment is made: for each stroke less than the norm, for example, for a 6-year-old child 96 strokes, 1 point is awarded; the pulse rate for 1 minute gives 30 points, the norm of this indicator for children is estimated by A.P. Khripkov; with a pulse above 95 beats per minute, points are not awarded;

- flexibility (cm), estimated flexion of the body with a maximum amplitude (cm); when completing a task corresponding to the age norm, 1 point is awarded, each centimeter above it is also 1 point, if the regulatory requirements are not met, points are not awarded;

- speed (cm), assessed by the ability to catch a ruler falling in free fall in a standing position, with an arm extended forward in front of the chest; the test result of three attempts is estimated by the median, 12 points are awarded for fulfilling the age standard;

- dynamic force (cm), estimated by the height of jumping from a place by the push of two legs, according to the method of V.M. Abalakova; the age norm is met and every centimeter in excess of it is estimated at 2 points, 3 attempts are made in jumping, the assessment is made according to the median;

- speed endurance (times), estimated flexion of the trunk in supine position for 1 minute; at this pace, the maximum frequency of lifting straight legs to an angle of 90 degrees with respect to the body from a supine position in 30 seconds is calculated; the age norm is estimated and each rise above it - at 3 points;

- speed-strength endurance (times), the frequency of flexion and extension of the arms at rest lying down for 30 seconds is estimated; fulfillment of the age norm and each push-up that exceeds it is estimated at 4 points;

- total endurance (m), the distance of a 6-minute run is estimated; for the fulfillment of the age norm, the following is accrued: 30 points for every 50 meters that exceed the norm; 15 reward points; for every 50 meters below the established standard, a total of 5 points is calculated;

- the recoverability of the pulse (bpm) is estimated as follows: in the sitting position, the pulse is measured in 10 seconds (the result is multiplied by 6), after 20 deep squats are performed for 40 seconds, the pulse is measured again in 10 seconds and the result is multiplied by 6, we get pulse at rest; then the standard load is given - 20 deep squats for 40 seconds and the subject sits down again, after 2 minutes he again measures the pulse in 10 seconds and his result is multiplied by 6; correspondence of the pulse during repeated testing to the norm, after 2 minutes, the initial value - 30 points; an excess of the pulse by 10 beats is considered 20 points, by 15 beats - 10 points, by 20 beats - 5 points, more than 20 beats - points are not awarded. Having assessed the qualities and abilities by 11 indicators (parameters) in points, their sum is calculated. Assessment of the result on a scale of 5 levels of physical fitness are given in table 5.

Table 5 Grading scale Body conditions 1. Low - 55 points Pathology condition 2. Below average - 56-95 points Pre-disease condition 3. Average 96-165 points Norm Status 4. Above average - 166-255 points Norm Status 5. High - over 255 points Norm Status

Identified conditions of norm or pre-illness, or pathology are not sufficient to determine the impact of training sessions in a natural training process, in particular the reserve capacity of the body. Additionally assess the index of physical condition (IFS) by parameters:

- (PE) resting heart rate;

- (DM) systolic pressure;

- (DD) diastolic pressure;

- (B) the age of the subject;

- (MT) body weight of the subject;

- (P) growth (body length).

After measuring these parameters, the physical state index (IFS) is determined by calculation by the following formula:

where PE is the resting heart rate;

SD - systolic pressure;

DD - diastolic pressure;

B is the age of the subject;

MT - body weight of the subject;

P - growth (body length).

Assessment of the reserve capabilities of a growing student’s body in a natural training process, taking into account the individual level of physical condition, is carried out using qualitative assessments (UFS) of the levels of physical condition, presented in the form of a five-point scale and are given in table 6.

Table 6 UFS (level of physical condition) The range of values of IFS (index of physical condition) Reserve capabilities of a growing student body 1. Low Less than 0.375 Low backup capabilities 2. Below average 0.376-0.525 Low backup capabilities 3. Medium 0.526-0.675 Medium Standby Opportunities 4. Above average 0.676-0.825 High backup capabilities 5. High 0.826 and higher High backup capabilities

The impact of training sessions is also evaluated by indicators of the hemodynamic components of the cardiovascular system using orthostatic tests. Evaluate indicators of minute (IOC) and shock (UO) blood volume, heart rate (heart rate), IN indicators in the supine and orthoprobe samples (table 7) in comparison with the average indicators of hemodynamic status.

Since resistance to orthostasis directly depends on the state of the muscles, physical activity will provide increased endurance due to aerobization and reduced compliance by increasing muscle mass around the veins. Therefore, with a low level of physical fitness equal to 55-95 points, and a value of the index of physical condition equal to 0.375-0.525, a change in blood pressure by more than 20% compared with the norm, an increase in heart rate and a deviation in the value of IN by more than 20% increase aerobic anaerobic endurance training by the additional inclusion of cyclic exercises. The intensity of physical activity is chosen within 60-75% of the maximum with regularity in the weekly cycle at least 3 times a week. The motor mode is supplemented by static power loads, the intensity of which is set 60-70% of the maximum.

Correction of the type of training is carried out taking into account the values of indicators of physical development, evaluated by a number of somatoscopic, somatometric and physiometric indicators of the level of age development.

To determine the values of the set of indicators characterizing the state of physical development, the parameters of the foot, posture, height, weight, weight to height, lung capacity, weight-to-lung capacity ratio, dynamometer of the right hand, dynamometry of the left hand, stanza, stanza are measured forces to body weight, dynamic force. The parameters of the measured indicators are compared with the norm indicators; for this, a three-level evaluation scale is used, in which the studied value of the indicator is compared with the norm in accordance with the arithmetic mean sample. A student with a deviation of the studied indicator in the direction of increasing or decreasing by X + 2σ or X-2σ is included in the group including parameters above or below the average level.

If the values of one or several indicators characterizing the complex state of the body go beyond the control average standard, then the exercise includes physical exercises aimed at restoring the proportionality of the physique, and the dosage of the prescribed physical exercises is increased if the value of the physical fitness indicator obtained before the adjustment was below the control average standard of the student’s age group.

An integral indicator of physical fitness contains parameters of age, body weight, blood pressure, resting heart rate, spinal column flexibility, speed, dynamic strength, speed endurance, speed-strength endurance, general stamina, and pulse recovery.

The physical state indicator contains parameters of body weight, blood pressure, resting heart rate, age and height.

For the characteristics of the hemodynamic components, indicators of the minute and stroke blood volume, heart rate, and the IN index in the supine and orthoprobe samples are selected.

For somatoscopic characteristics, indicators of the foot and posture are selected.

For somatometric characteristics, indicators of growth, weight, the ratio of weight to height, vital capacity of the lungs, the ratio of weight to vital capacity of the lungs are selected.

An example of a specific implementation of the method.

Correction of physical qualities and abilities of a student of K-11 was carried out on the basis of his condition, functionality, level of development of physical qualities and fitness.

According to the diagnostics (testing) carried out at the beginning of the school year, the subject revealed significant deviations in the state of the cardiovascular system, the basic physical quality - speed-strength endurance (see the first row of the profile of the student’s physical fitness profile shown in figure 2 11 years).

Flattening of the arch of the foot, a low level of physical development - VC - 1388.74 ml and vital index (VC / Body Weight) - 56.91 were also identified.

In order to correct lagging qualities and functional abilities, Kn was offered an individual training program that includes the following training tools: running (cross) 15-30 minutes - with low and medium intensity with 2 times a week. This load was carried out during the first six weeks. Over the next 6 weeks, the following were performed: running (cross-country) with an average intensity of 20-40 minutes - 3 times a week, skiing - a 3-km distance with an average intensity of 3 times a week, where the state of the cardiovascular system was adjusted . In parallel with this, a correction of the arch of the foot was carried out with the proposed set of exercises at home. It consisted of exercises of power and speed-strength nature and included 2 exercises with the following dosage:

- exit to the socks from the position of the main rack with a dumbbell (6 kg) on the shoulders - 25-30 repetitions in four approaches;

- jumping to a depth of 35 cm in elevation, followed by pushing away from the support with legs and 10-12-fold repetitions in five approaches.

A set of exercises for correcting the arch of the foot was performed for 6 weeks and was included in the morning exercise as a prerequisite.

According to repeated diagnostics (testing), conducted six weeks later, K-on stabilized - blood pressure, pulse at rest and its recovery, formed the arch of the foot. The level of development of speed-power endurance increased to standard age limits (see the 2nd row of the profile of the physical fitness profile of a student K-11 years old, shown in Fig. 2).

The indicators of physical development — VC and life index — increased to 1985.17 ml and 62.75, respectively (with an age norm of 1487.71 and 58.59).

The proposed method allowed us to adequately affect the cardiovascular system, which is the most labile, vulnerable and vulnerable in comparison with other body systems, namely, to strictly dose the pulse cost, as a condition of unacceptable forcing of correction loads (first and second six weeks). With corrective actions, it is determined by the training heart rate (TCHS) according to the formula below. For example, the reserve of maximum heart rate (RMSC) is defined as the difference between the maximum heart rate and heart rate at rest. If for this age group of students heart rate for classes is recommended 150 bpm / min, as the maximum, then heart rate for corrective training load (TSS) is calculated by the formula: TSS = 80 + 0.60 (150-80) = 98 bpm .

From the monitoring data of the proposed method, it follows that the increase in physical qualities for those involved in the applied technology amounted to:

- 8-12% for children of primary school age;

- 11-16% for adolescents;

- 13-27% for boys and girls and engaged in specialized groups.
