Teachers for the note: physical development is an indicator of a child's health

It's no secret that if you compare medical cards and the results of physical examinations of current schoolchildren and those who took their place several generations ago, the differences will be significant. Their parents and even grandparents were much stronger and healthier. The reasons for such a change in the health of children are many, both external and objective (poor ecology, the chemicalization of food products, exorbitant loads associated with learning), and subjective, intrafamily (heredity, living conditions, material wealth of parents, psychological climate, etc.) To reveal any deviations from the norm can indicators of physical development.

Interpretation of the term

First, let's define what physical development is. These are the rates of growth and physiological maturation of the child in this or that period of his life. Such indicators include growth, weight, full functioning of all organs and systems of the body. It is well known how close the body weight of a boy or girl should be to a year of life, as well as height, length of limbs, etc., their mutual proportionality. And the comparison of real results with standards shows how much the physical development corresponds to or behind the norm at each stage of the growth of children .

This is important to take into account, so that it is possible to create optimal conditions for children to live, and also to keep statistical records of anthropometric indicators. After all, we must not forget that the physical condition of any person, including a child, dependencies T not only from genetic and biological factors. Sanitary, hygienic, socio-economic and other conditions affect it no less. In addition, physical development is also physiological processes that are constantly occurring in the body. Therefore, for each period of growth and maturation are characterized by their mental, biochemical, morphological and other parameters and characteristics.

Ideally, a high level of physical development should be combined with the same work capacity of muscles and brain. In the period of intensive growth of the body, just such a harmonious combination is of fundamental importance. Proceeding from the foregoing, we can conclude: physical development is the data on the morphological and functional state of the child.

Main factors

What does this data refer to? Firstly, for how long can a child perform work feasible without clear signs of fatigue? This is the so-called "aerobic" endurance. Secondly, the level of physical development is also considered through the speed endurance indicators - Bots at high speeds. Thirdly, power loads - they test the endurance of the muscular system. Then follow the joint indicators for speed-strength endurance, flexibility, muscle volume, dexterity, and, finally, mutual correspondence of the bone system of the body, muscle, tissue and fatty interlayers. It in many ways makes it clear to what extent the child is ill or ill. Finally, the physical development of schoolchildren is determined by their posture, which gives a comprehensive idea of its musculoskeletal system.

Thus, taking care of the full physical development of each child, the state, social bodies, family take care of the future health of the whole nation.
