may contain oxygenated chemicals such as ethanol, MTBE, or ETBE.

CONTROL OF THE CORRECT FORMATION OF CADENCE IN PRESCHOOL
CHILDREN
B. Masharipova
Abstract: keeping the health of children in the modern conditions,
establishing their proper development is one of the most urgent professions.
After all, the future of our country is in the hands of youth. Therefore, control
over the formation of cadmium in children.

The main purpose of educating children from the physical side during
preschool education is the formation of various skills and abilities in
children, in addition to the development of physical qualities such as
strength, agility, alertness in them, their dignity ensures the correct
formation and soundness. Regularly conducted physical exercises positively

affect the growth and development of children, increasing their creative
capacity.
What is the right posture before talking about posture in preschool
children?, I will answer the questions of how it is formed.
Correct posture is a normal standing position of the human Gav, which
can develop correctly and incorrectly. Proper development of posture is felt
from the standing of the spine and footrest, the foot is light and easy to lift
when walking, running, jumping, keeping all internal organs in walking: the
chest, abdominal cavity, Gav in such a position that it is satisfied with the
implementation of any movement. This situation in a person who bent his
head, squatting his shoulders, moving his belly forward and throwing his
legs all the way out is that the step is formed incorrectly.[1]
As we understand, since the correct or incorrect formation of the Kamen
is tied to how it develops from an early age. Now for the correct formation
of such a figure, children strictly adhere to the order of the day, proper
nutrition and, of course, physical exercises. The first factor in the correct
formation of posture is physical exercises. Regular stretching with physical
training will help to form the right posture. Therefore, corrective
(corrective) exercises are introduced into theeksex of gymnastic exercises.
Moving games in the formation of the right step are very useful. If the wrong
formation of menstruation is now beginning, it is eliminated with the help
of morning Gymnastics and physical exercises.
The development of the musculoskeletal system in children is due to the
fact that it is still in progress, the bones are bent and prone to change, as well
as due to improper sitting on the chair, improper posture and other reasons.
Also it is harmful to use furniture that does not fit the neck. Not only in the
kindergarten, but also furniture in the House should be in such a way as to
fit the height of the children. Bunda is selected by making the height of the
chair so that the hens fully rest against the ground, forming a right angle of
the thigh and thigh. If the chair is higher, then something is put under the
foot. If the chair is lower, then it is necessary to lower its leg. If the table is
suitable for a chair, then the distance from the eyes to the book will be 30-
35 CM, and the hands and palms will lie flat on the table, allowing you to sit
straight. At the time of reading, writing, the chair should stand next to the
table by 3 - 5 cm, not leaning on the edge of the table with the chest. From
gavda to the edge of the table should leave a place on the width of the palm.
Wrong posture is also encountered in children who are very ill. They
quickly get tired during training, as a result of which it is observed to sit or
stand in the wrong position. Later, in this case, you're getting used to sitting.
At this time, every educator who knows his work well should not ignore this
situation and, of course, should not overlook such situations when eating
with children, in training and in games. This in turn will not allow the

formation of incorrect posture. Another thing to mention here is that during
training the room is not properly illuminated, which also leads to a
curvature of the spine. But in the Normal case, our room should be fully lit
and the light should fall from the left side. The reason is that during the
training in a fully lit room the child will have to bend his head so that I look
at the book closer to the notebook and some kind of training material. Of
course, such requirements are defined in the state program "first step" of
the document approved by the decision of the Ministry of preschool
education of the Republic of Uzbekistan on July 7, 2018 meeting of the jury.
This educational program is a normative legal regulation, developed in
accordance with the requirements of the basket on the development of
children of the first and preschool age of the Republic of Uzbekistan, in
which the goals and objectives of preschool education organizations, the
main ideas of educational activities are expressed, as well as the main
compartments on the transition to the next [2]
How to check the correctness of cramps in children
It is easier — than with attention. The child is checked in the standing
position from side to side (it is necessary that it is 1,5—2,0 meters away
from yourself).
During the examination, of course, attention is paid to the fact that the
head is held, bent forward or backward, The Shape of the chest, the
abdominal line, the knee joint bend, the neck, chest and waist curvature of
the spine.
And in the examination of the child in the face-facing position, it is
necessary to pay attention to the fact that his shoulder area is the same.
When checked in the standing position with the back, it is observed that his
shoulders, the lower corner of the chest are the same and are the same
distance from the spine. Then the child is checked by bending 900 forward
(the knee does not bend, the hand hangs). It can be seen that the two halves
of the Bunda shovel areas are either the same, or the left is either the right
shovel area.
The child should not sit down until 6 months, but from 3 months it is
desirable to lie on his stomach more often. Until 9 months, it is
recommended not to rush the child to the feet.
It is not recommended to lead the child by one hand, it is necessary to
walk as far as possible on its own, otherwise the weight on the spine may fall
and cause some defects. Giving children gymnastic exercises gives positive
results.
Children of preschool age should be able to travel more outdoors, play
different games. If the child is diagnosed with rickets, the parent must
immediately contact the children's doctor and seek advice.

For the prophylaxis of Thrush, of course, paying attention to the
exercises ofeksex Gymnastics from the age of 2-3 years, training of skiing or
skiing from the age of 3 years will bring good results. [3]
Qomat is usually not included in the range of indicators by which
research work is carried out. From a young age, it begins to take shape and
change throughout life. Basically, the formation of Thrush occurs at the age
of 6-7 years, and the development of Gav muscles in its formation is of great
importance. This is the tension of the muscles, keeping the torso in shape
and in the supine position, while their reduction leads to its contraction.
Since gavda muscles in children are still weakly developed, their posture
becomes unbearable. The formation of the figure is one of the main tasks of
the physical education of o'hors. The main criterion here is the technique of
doing exercises in one plane and the hormonal development of all group
muscles. By the age of 18, the spine stabilizes, and after that it is very difficult
to fix it.
In place of the conclusion, we can say that from birth it is necessary to
pay serious attention to the health, nutrition and of course the actions of
children. Because from this period begins to form gradually. In children, the
figure is formed until the age of 18 years, and in this range, if they are well-
groomed and follow hygienic rules, then the figure is formed correctly and
beautifully.
