Made observations 9300 in children 5-20 years. Expected amount of calcium, dietary intake and measured at densitometre as it affects the content of minerals in the skeleton. Shown that calcium intake infl uences the type of Constitution and development of the skeleton. Boys more than girls, consume calcium from food, so they in the bones of the skeleton minerals more at 25-30 %. It is very important to stress that only regular and prolonged consumption close to normal amounts of minerals increases the mineralization of organic base skeleton. This process accelerated under the infl uence of increasing concentrations of sex hormones, and therefore the period of puberty is reached peak bone mass. Intensive physical work somewhat increases the amount of calcium in the skeleton. Parallelism between the amount of dietary intake of calcium and mineral bone density of the skeleton does not exist. This is explained by the fact that the intake of calcium is affected by the concentration of vitamin D3 is produced in the kidneys, and the mikrovibraciâ of muscle fi bers, the energy that moves minerals and nutrients from the interstitial space to bone cells, as well as the vsasyvatel′naâ ability of the small intestine.
