It is no secret that if you compare medical records and the results of medical examinations of current students 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 children's health are many, both external, objective (poor ecology, chemicalization of food products, exorbitant loads associated with learning), and subjective, intra-family (heredity, living conditions, material well-being of parents, psychological climate, etc.) Help indicators of physical development can identify certain deviations from the norm.
Interpretation of the term
To begin with, we will determine what physical development is. These are indicators of the growth and physiological maturation of the child in one or another period of his life. These indicators include height, weight, the full functioning of all organs and systems of the body. It is known what approximately the body weight of a boy or girl should be by a certain year of life, as well as height, length of limbs, etc., their mutual proportionality. And a comparison of real results with standards shows how their physical development corresponds or lags behind the norm at each stage of children's growth.
This is important to consider, so that children can create optimal conditions for life, as well as to conduct statistical accounting of anthropometric indicators. After all, we must not forget that the physical condition of any person, including a child, depends
t not only from genetic and biological factors. Sanitary, hygienic, socio-economic and other conditions affect him no less. In addition, physical development is also physiological processes constantly occurring in the body. Therefore, each period of growth and adulthood is characterized by its own psychic, biochemical, morphological and other parameters and characteristics.
Ideally, a high level of physical development should be combined with the same performance of muscles and brain. During the period of intensive growth of the body, such a harmonious combination is of fundamental importance. Based on the foregoing, we can conclude: physical development is data on the morphological and functional state of the child.
Main characteristics
What is relevant to this data? First, how long can a child do what he can do without obvious signs of fatigue? This is the so-called "aerobic" endurance. Secondly, the level of physical development is also considered through high-speed endurance indicators - the performance of
bots at high speeds. Thirdly, power loads - they test the endurance of the muscle system. This is followed by joint indicators on speed-strength endurance, flexibility, muscle volume, dexterity and, finally, the mutual correspondence of the body’s bone system, muscle, tissue and fatty layers. It largely makes it clear to what extent the child is in health or ill health. Finally, the physical development of students is determined by their posture, which gives a comprehensive picture of his musculoskeletal system.
Thus, taking care of the full physical development of each child, the state, social organs, and the family take care of the future health of the whole nation.
