[Increasing of functional abilities of pre-school children by means of physical training].

A complex of physical training measures for preschool children has been developed and tested. It includes varied exercises and conditioning exposures, exercises of moderate intensity should make for 65-75%, those of low intensity 15-20%, and those of high intensity 10-15% of their regime. Taking into account the specific features of children, as much as 70% of motor activity should be realized during various organized physical exercise lessons, the younger the child is, the higher activity is.

[Differential assessment of the health status of preschool children in risk groups].

Health status of the underschool children from the second health group, which with having some morphofunctional changes, (503 persons) was studied. The key changes were postural, cardiovascular, neuropsychic changes. The lysozyme level in saliva is the informative index related to the health status of underschool children.

[Changes in the physical development of preschool- and elementary-school-age children in Moscow during the last twenty years].

Analysis of the 4-10-aged children habitus (above 8,000 persons) in Moscow from 60-th to nowadays shows the growth acceleration from middle 60th to 70th, and then, from 80th to nowadays, significant decreasing of growth parameters.

[Optimal air conditioning in the classrooms of secondary schools as a factor of improving health status of schoolchildren].

Proceeding from the analysis and statistical processing of the data derived during the study of health dynamics of junior schoolchildren, who studied during an academic year under the conditions of different air exchange regimes (20 and 40 m3 of air per hr/child), it was established that indoor air medium formed by air supply of 40 m3 per hr/child (compared to 20 m3) even during a year had a favorable impact on the functional state of some body systems and prevalence of acute diseases among schoolchildren.
