Research and assessment of human physical health
Purpose of work: to master the methods of physiometric studies; methods for determining the state of physical health of a person.
1. The concept of physiometry. Determine the functional parameters of the body: vital lung capacity (VC), heart rate (HR), blood pressure (BP), muscle strength of the hand of the leading arm.
2. Using the results of anthropometric measurements, identify the correspondence of your body weight to growth, determine the body proportionality index, as well as body strength, type of constitution, level of chest development, dynamometric (power) index (CI) of the hand. Compare the obtained data with the norm and draw the appropriate conclusions.
3. Perform a physical exercise test. Given the recovery time of heart rate after performing physical activity, the calculated ratio indices based on the data of anthropo- and physiometric measurements, determine the level of your physical health.
4. Conduct a definition of an individual level of health by a set of indicators.
Guidelines for implementation
1. Perform laboratory work "Determination of physiometric indicators"
1.1. Determination of vital lung capacity (VC)
Working process. Set the spirometer scale to zero. Trying to stay upright, without slouching, after 2-3 calm breaths and exhalations, take a maximum breath, pinch your nose and exhale evenly, as deep as possible into the spirometer. Repeat measurements 3 times and record the maximum result.
1.2. Determination of the strength of the muscles of the flexors of the hand
Working process. In a standing position, take an outstretched arm with the device to the side at a right angle to the body. The second, free hand is lowered and relaxed. Squeeze the dynamometer with the utmost effort, but without jerking or any additional movements with your hand or body. Repeat the test 2-3 times and evaluate the strength of the muscles of the hand for the best result.
1.3. Pulse rate measurement of heart rate (HR)
Working process. The heart rate by palpation is most often determined on the radial artery. With the second, third and fourth fingers of the leading hand, feel for the pulse on the radial artery of the left hand. In this case, the fingers in the joints bend so that their nail phalanges are perpendicular to the palmar surface of the forearm. Count your heart rate within a minute.
1.4. Determination of blood pressure (BP) by the auscultatory method N.S. Korotkova
Working process. (The work is done together). Sitting on a chair, the test subject puts a relaxed hand on the table, put a cuff of a membrane tonometer on his bare shoulder. Its lower edge should be separated from the elbow by at least 1-1.5 cm. In the ulnar fossa, find the pulsating brachial artery on which you put a phonendoscope (a device for listening to sounds coming from the organs of the body). Take the rubber bulb with your leading hand, placing the index and thumb fingers on the valve, close the valve. Squeezing and lowering the pear, pump air into the cuff, creating a pressure in it above the maximum, the pulse disappears. Turning the screw valve, slowly release air from the cuff, listening to the vascular tones that appear in the brachial artery.
Mark the moment of appearance of tones corresponding to systolic pressure according to the reading of the device. Continue to lower the pressure in the cuff and listen first to the increasing strength of the tones, and then their weakening and disappearance. Record the reading of the instrument at the moment the tones disappear, which corresponds to diastolic pressure. The values of systolic and diastolic pressure are expressed in millimeters of mercury (mmHg).
1.5. Enter the results of all measurements in table 4.

2. Perform laboratory work “Research and evaluation of proportionality, physique strength, body weight to height, chest development by index method”.
2.1. Determining the proportionality of the physique by the Pirke index
The Pirke index or body proportionality index is calculated using the formula:
Normally, the body proportionality index is 87-92%, and for women it is slightly less than for men.
2.2. Determination of physique strength by the Pinier Index (1901)
The physique strength is determined by the Pinier index:
Pigne Index = Height, cm - (Body weight, kg + OGK, cm)
The smaller the index numbers, the stronger the body. Assess the result by table 5.
EVALUATION OF BODY FORTRESS
M.V. Chernorutsky (1929) the values of PI were used to determine the type of constitution (physique) of a person.
According to the classification of M.V. Chernorutsky, for normostenics, IP is from 10 to 30, for asthenics - more than 30 and for hypersthenics, IP is less than 10.
Analyze the data obtained and determine your type of constitution according to M.V. Chernorutsky.
2.3. Determining the correspondence of body weight to growth
To determine body weight and height, calculate body mass index (BMI):
The zone of the norm is the value of the index, equal to from 22 to 24.
2.4. Determining the level of development of the chest
Determine the level of development of the chest by calculating the index of proportionality of the chest (IPHC):
An indicator from 50 to 55% corresponds to normal development, more than 56% to excellent development, less than 50% to insufficient, poor development of the chest.
2.5. Compare the obtained data with the estimated indicators and draw a conclusion about the proportionality, physique, type of constitution, correspondence of body weight to growth, and indicate your level of development of the chest.
3. Perform laboratory work “Research and assessment of the degree of development of the strength of the muscles of the flexors of the hand of the leading arm”
Determine the degree of development of the muscles of the hand by calculating the dynamometric index (CI) of the muscles of the flexors of the hand:
Evaluate the results obtained using table 6.
The indicator of the received CI should be entered in table 8 (column "Indexes of the ratios of the subject").
EVALUATION OF DIA DETERMINATION RESULTS
3.1. Make a conclusion about the degree of development of muscle strength of the flexors of the hand of the leading arm. Compare the data obtained with lifestyle features (systematic visits to the sports section and exercise, physical inactivity, type of constitution, etc.) or with the presence of diseases.
4. Perform laboratory work: "Determining the level of human health by a set of indicators (according to G.L. Apanasenko and R.G. Naumenko)."
To determine the level of physical health, do the following:
4.1. Perform a test with physical activity. Before performing the sample, copy table 7 to the notebook.
Working process. Determine the heart rate at rest in 10 seconds and enter the result in table 2. Perform 20 deep squats in 30 seconds (legs shoulder width apart, squat, stretch your arms forward, standing up - lower). Then, sitting, count the heart rate for 10 seconds at the end of the first, second, third, etc. minutes before it is restored. Enter the results in table 7.
RESTORE THE PULSE AFTER PERFORMANCE OF THE PHYSICAL LOAD
FULL NAME. subject _____________________________________________
The recovery time of heart rate, in minutes, after 20 squats in 30 seconds, is entered in table 8.
HEALTH ASSESSMENT BY COMPLEX OF INDICATORS
(BY G.L.APANASENKO AND R.G. NAUMENKO)
4.2. Perform calculations using previously obtained results of anthropo- and physiometric measurements (Tables 1 and 4). Copy table 8 into a notebook and enter the results of all calculations in the column “Indexes of the ratios of the subject”.
4.3. Using the obtained heart rate (HR) and blood pressure (BP) values at rest (Table 4), find the product of heart rate by the value of systolic blood pressure (BP), and dividing the result by 100, enter it in table 8.
4.4. Using the data of table 9, put down in table 8 the points that you received when determining the indices of the ratios. Calculate the total amount of points and, comparing it with the values indicated in table 9, indicate your level of physical health.
DETERMINATION OF INDEXES OF RELATIONSHIP OF A TESTED IN SCORES
4.5. Determination of an individual level of physical health (according to E.A. Pirogova, 1987)
Working process. Using indicators of heart rate and blood pressure (Table 4), body weight and growth (table 1), determine the individual level of physical health (IHF) according to the formula: IHF = (700-3CHS - 2.5 ADdiast.) + (A.sist. - ADDiast.) / 3 - 2.7V + 0.28M) / (350 - 2.7V + 0.21P), where heart rate, beats / min - heart rate; ADSist. - systolic blood pressure, mm. Hg. st .; ADDiast. - blood pressure diastolic, mm. Hg. st .; P - height, cm; M - body weight, kg; In - age (number of full years).
Evaluate the results obtained using table 10.
INDIVIDUAL LEVEL OF PHYSICAL HEALTH
4.6. Compare the data of determining the individual level of physical health according to the method of G.L. Apanasenko and R.G. Naumenko and E.A. Pirogova. Obtaining similar estimates of the level of physical health using both methods is evidence of a rather high accuracy of your level of health. Make a conclusion about the state of your physical health. Compare the results with the features of your lifestyle and the presence (absence) of diseases.
