[Scientific bases of the improvement of and planting of trees and bushes in the playgrounds of outbuilding areas].

The major factors forming the environment of a current megapolis, such as man-made pollution, planting of trees and bushes (outbuilding and street plantings, proximity to the large forest tracts), and improvement of microdistricts (the presence of playgrounds equipped in compliance with the age-related and physiological and hygienic requirements), on the health status of children. The comprehensive evaluation of the physical development and the health status of schoolchildren aged 6 to 10 years shows that the children who live at equal distances from the major source of environmental pollution and have the equal social status and the identical level of health care, but differing in the remoteness from the large forest tract and in the improvement of planting of trees and bushes in the playgrounds they have significant differences in the physical development, overall morbidity, and the prevalence rates of chronic diseases. While planning the playgrounds of the micro-districts and outbuilding areas, it is necessary to draw up hygienic regulations of their improving and planting.

[Impact of present-day forms of organization of physical education on the health status of preschool children].

During a natural hygienic experiment, the physical development, psychomotor activity, exercise performance, and readiness were evaluated in 6-year-old children, in whom physical education had been organized by routine and experimental programs, including health-improving swimming in the indoor pool of a preschool educational establishment. Exercises built up on the principle of plot-role playing games, by using the developing corrective exercises and psychological and pedagogical escort, were established to be highly effective. The proposed methods contribute to the timely harmonious development of a child, his movement characteristics, positively affect the neurofunctional status, by ensuring the optimum psychomotor development, and maintain a high exercise performance.
