no secret that if you compare the medical records and the results of medical examinations of current students and those who take their place a few generations ago, the differences are considerable.Their parents and even grandparents were much stronger and healthier.The reasons for such a change children's health a lot, both external, objective (a bad environment, use of chemicals in food, exorbitant burden related to their studies) and subjective, intrafamily (heredity, living conditions, material prosperity parents, psychological climate, and others.) Helpreveal certain deviations from the norm can be indicators of physical development.
interpretation of the term
To start to define what physical development.This growth performance and physiological maturation of the child in a particular period of his life.These indicators include height, weight, the full functioning of all organs and body systems.We know approximately what weight should be a boy or girl to a certain year of life, as well as growth, length of limbs and so on. E., Their mutual proportionality.And comparing actual results with the standards shows how meets or lags behind the rate of growth at each stage of their children's physical development.
This is important to be able to create optimal conditions for children for life and to a statistical account of anthropometric indicators.You can not forget that the physical condition of any person, including a child, depends not only on genetic and biological factors.Sanitary, socio-economic and other conditions affect it less.In addition, physical development - is constantly committed in the physiological processes of the body.Because 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 a working capacity of the muscles and the brain.In the period of intensive growth of the organism is a harmonious blend of fundamental importance.Based on the foregoing, we can conclude that the physical development - is data about the morphological and functional status of a child.
Key indicators
What is this data?First, how long a child can do for himself all possible work without obvious signs of fatigue?This so-called "aerobic" endurance.Secondly, the level of physical development is considered and performance through high-speed endurance - to work at high speeds.Third, the power load - they test the endurance of the muscular system.This is followed by a joint performance in the power-speed endurance, flexibility, muscle volume, agility and, finally, mutual conformity of the body's bone, muscle, and fat tissue layers.It largely makes clear the extent to which health or ill-health is a child.Finally, the physical development of pupils is determined by their posture, which gives a comprehensive picture of its locomotor system.
Thus, taking care of the full physical development of each child, the government, social agencies, family care about the future health of the nation.
