Korinchak L. Age peculiarities changes action cardiovascular system in seasonal biologic rhythm

The article deals with age peculiarities of cardiovascular system changes in seasonal biologic rhythm. In the scope of the research eight, ten, twelve-year pupils have been examined in different seasons of the year since these age groups are to be considered the most important phase of forming physiological functions systematically. Human health functional parameters and resources are formed at this age as well as intensive developments and improvements taking place due to morphological and functional brain maturing. Different functional tests have been conducted for analyzing functional and reserve capabilities of cardiovascular system, such as systole frequency, systolic and diastolic arterial pressures with the calculations of systolic and time Kerdo index and other indices characterizing the function of cardiovascular system. Also electrocardiograms have been checked, and changes of cardio intervals values, vital lung volume, weight-height Kettle index, Schtange test, tapping test, muscle staying power have been examined. Experimental test of seasonal biorhythms cardiovascular system activity changes in pupils of different age groups and man's physical parameters have been the aim of our research. Recommendations have been developed for physical training teachers and medical workers on this ground, since parameters of the organism change considerably due to human organism biorhythms of physiological indices including seasonal endogenous variations of physiological processes intensity. We presume that the given principles of a child's organism vital activity conditions should be taken into consideration in the process of education of different age groups; firstly, with the aim of changing educational process to constrain mental and physical load onto a child, since additional seasonal factors may influence children health parameters significantly; secondly, additional personal corrections of children physical and emotional conditions should be used so that to normalize the parameters of their organisms which might help to accept all educational, mental, physical and social loads conforming with capabilities of this age group Scope of use: physiology, ecology.
