INTRODUCTION
One of the bio-socially important stages of the
ontogenesis of the human organism is childhood,
during which a large number of serious changes take
place in the morpho-functional systems of the
organism. It is also noted that in this age period, in
connection with the beginning of the educational
process of a systematic description at school, the
effect of a new type of stress factor occurs. In
particular, in most cases, it is noted that innovative
technologies introduced into the educational system in
secondary schools at the stage of modern
development, the complex structure of lesson
programs do not correspond to the functional
capabilities of the children's organism.
The response reaction of the morpho-physiological
systems of the human div to the influence of various
endogenous/exogenous factors is directly determined
by the somatotypological characteristics of the
organism depending on the physiological age. In
particular, indicators of the physical development of
the child's div are important as a reliable marker of
the successful implementation of adaptive capabilities
under the influence of various factors [Chub, 2013; p.
3].
In scientific studies conducted in many countries of the
world, the optimal development of the level of physical
activity of students requires taking into account the
individual characteristics of schoolchildren depending
on their physiological age when organizing physical
education classes. In the conducted studies, it is
possible to determine the decrease in the activity of
the musculoskeletal system, the main functional
systems of the div of children and adolescents under
the influence of the decrease in the level of physical
activity and, in turn, the increase in the level of
susceptibility to various diseases. Determining age and
gender-related specific characteristics of elementary
school students at the level of physical development,
evaluating their physiological changes based on the
indicators of the morpho-functional system, are
considered as promising directions of current research.
Therefore, in determining the health of elementary
school students, analysis based on indicators of
physical development and preparation, development
of a complex of medical-pedagogical correction,
preventive measures acquires important scientific and
practical importance.
Monitoring of physical development is also relevant
from the point of view of determining the level of
development of the children's div of different ages,
as well as allowing timely recording of deviations from
the standard level and implementation of appropriate
corrections. [Antonova A.A., 2012; pp. 26

Research materials and methods:In studies, measuring
the height of students (cm) using a stationary height
measuring device (GOST 16371
–
93, 19917
–
93) is a
standard method [Erenkov V.A., 1984; pp. 10
–
336;
Safronov A.A., Arislanov I.T, 2013; pp. 455
–
458;
Pilkevich N.B, 2013; 30 p.], i.e., the test subject was
placed in a standing position on a special platform with
the soles of the feet paired and the div upright, the
shoulders in a straight position, the hump and the
shoulder blades touching the middle of the device. In
this case, attention was paid to the fact that the div's
heel, buttock, chest area and the back of the head
touch the measuring column, and the eye area and the
lower part of the upper ear are located in one plane.
The head is held in an upright position facing forward,
The sliding special board of the measuring device is
lowered until it touches the top of the head and the
value (cm) is recorded [Muratova I.V., 2009; pp. 59
–
61].
Body weight measurement (kg). In researches, the
div weight of elementary school students was
measured using a medical scale (TU 9441
–
004
–
00226425
–
2005) using a standard method [Rakhimov
M. I., 2011; pp. 10

336; Korobko R.P. 2002; pp. 455
–
458;
Karakeeva G.J., 2012.; p. 30; Nechaev M.P., 2001; 3

p.], that is, the div weight of the student under test
was determined by weighing on a medical scale in the
state of taking off his clothes except his underwear
(the accuracy of the measurement is ±50
–
100 g).
Measurement of the length of the chest circumference
(cm) - standard method [Rakhimov M. I., 2011; pp. 10
–
336; Korobko R.P., 2002; pp. 455
–
458; Karakeeva G.J.,
2012; p. 30], in which the value of this indicator was
measured in a student under test using a centimeter
measuring tape (GOST R 50444
–
92) in the state of rest,
maximum inhalation, maximum exhalation. In this
case, the chest circumference (cm) of students was
measured in a standing position, with arms lowered
along the side of the div, at the level of the sternum
line (measurement accuracy is ±0.5 cm) [Pustozerov
A.I., Gostev A.G., 2008; pp. 7

In the experiments, hand strength was
measured using a dynamometer device (DPR-30,
"Kodex", Russia) while the subject was standing, the
hand being measured was bent at an angle of 90° to
the div, and the other hand was lowered. In this case,
the measurement was repeated 3 times in each hand,
and the largest value was recorded
The obtained results and their analysis:The obtained
results are the following L.V. Denisova et al. (2008)
mathematical-statistical processing using methods
[Albitsky V.Y.; pp. 125

The results are presented in the form of M ± t of the
results of the experiments carried out in p repetitions,
where M is the arithmetic mean value and t is the
standard error value.
Also, the statistical reliability level of the values
between the experimental results was calculated
based on the Student t-criterion and was evaluated as
statistically reliable at values of r<0.05, r<0.01. The
confidence level of the difference between the values
of two age groups was calculated according to the
Student test, using the following formula:
At the initial stage of the observations, in the general
education schools where the experiments were
conducted, the analysis of the physical development
level indicators was carried out based on the values of
the basic anthropometric indicators of the primary
school students (7-10 years old) - div weight (kg),
height (cm) and chest circumference (cm). In our
monitoring work, the indicators of physical
development of elementary school boys (7-10 years
old) of general education school No. 18 in Ulug'nor
district of Andijan region were studied. A total of 66
healthy and voluntary boys were included in the
observation.
Analysis of the obtained results. In our observations,
among the indicators of physical development, div
weight, height, chest circumference (at rest, in front of
the mammary glands when taking a deep breath and
exhaling deeply), indicators of the maximum
contraction force of the finger muscles were studied
and statistically analyzed, and the results were as
follows.

The average height of primary school children is
116.4±4.6 cm at the age of 7, 121.5±6.2 cm at the age of
8, 129.6±3.9 cm at the age of 9, 132.3 at the age of 10. It
was found to be ±5.4 cm.
It was found that the growth rate of height indicators
at school was 15.9 cm in the age range of 7-10 years, 5.1
cm in 7-8 years, 8.1 cm in 8-9 years, 2.7 kg in 9-10 years.
The length of the circumference of the chest (opposite
the mammary glands at rest) was determined in the
next part of our observations. In this case, the average
indicators of the length of the chest circumference at
rest in schoolchildren at the age of 7-10 years are
56.3±0.5 cm at the age of 7, 57.5±0.3 cm at the age of
8, 61.7±0.6 cm at the age of 9, 10 It was found that it
was 68.6 ± 0.6 cm at age.
It was found that the rate of growth of the value of the
chest circumference in schoolchildren increased by 12.3
cm at the age of 7-10, by 1.2 cm at the age of 7-8, by 4.2
cm at the age of 8-9, and by 6.9 cm at the age of 9-10.
During the observations, the average values of chest
circumference during deep breathing were 60.5±0.4
cm in the 7th year, 62.6±0.5 cm in the 8th year,
65.4±0.5cm in the 9th year, and 65.4±0.5cm in the 10th
year. and it was found to be 72.4±0.7cm.
Chest circumference in schoolchildren at the age of 7-
10 during deep breathing. The rate of increase in the
value of the chest circumference during maximum
inhalation is 12.2 cm in the age range of 7-10 years, 2.1
cm in the age range of 7-8 years, 2.8 in the age range of
8-9 years. cm, and at the age of 9-10 it increased by 7
cm.
During the observations, students between 7 and 10
years of age had an average of 54.6 ± 0.5 cm at the age
of 7, 55.8 ± 0.4 cm at the age of 8, 60.3 ± 0.4 cm at the
age of 9, 60.3 ± 0.4 cm at the age of 10. It was 4±0.5 cm.
It was found that the rate of growth of chest
circumference in schoolchildren was 10.8 cm at the age
of 7-10, 1.2 cm at the age of 7-8, 4.5 cm at the age of 8-
9, and 5.1 cm at the age of 9-10.
Based on the results of the research, it can be seen that
the values of the anthropometric parameters (div
weight, height, chest circumference) of primary school
boys of school No. 17, located in Ulughnor district of
Andijan region, increase linearly between the ages of 7
and 10.
CONCLUSION
The study of physical development indicators of
children aged 7-10 is of great importance in
determining the level of health of the growing young
generation. Based on the results of our research, we
can make the following conclusions.
1.
Body weight indicators increase dynamically
depending on age. The difference between 8-9 years
old is statistically inevitable (r<0.05).

2.
Total height indicators are also based on the
laws of growth and development and increase with
age.
Differences between 9-10 years old are significant and
statistically unavoidable (r<0.01).
3.
It was observed that the indicators of the
length of the chest circumference increased with age
in all three conditions (at rest, in deep inhalation and in
deep exhalation). Differences between 9-10 years of
age were significant (r<0.05) in rest and deep
exhalation. can be clearly seen in cases of inhalation.
4.
As a result of the above analysis, it can be seen
that the dynamics of growth between 9-10 years of age
is clearly noticeable in all indicators. So, compared to 7-
8 years old, growth and development accelerates
between 9-10 years old.
Suggestion. As we continue the analysis of the
obtained results and our observation work, we would
suggest to continue regular research and observation
work in order to find out the level of preventive health
of children of junior school age.
