Introduction.Considerably increased intensity of educational process in higher education institution frequently becomes the reason of deterioration in students’ health. The traditional system of physical education (PE), designed to maintain good health of students in new conditions, does not cope with an objective defined. Obviously, health preservation of a person is promoted by physical activities, which are adequate to his or her psycho-physiological characteristics and should be worked out individually for each person. The estimations can be carried out in different ways and on the basis of different parameters, among which the authors emphasise heart rate variability and vegetative regulation that act as indicators of adaptation and adaptive activity of an organism.The aimof the present research was to identify individual appropriate physical load for students with various motion behaviour types through the use of informational technologies (IT).Methodology and research methods.The research was based on health-preserving and differentiated approaches to physical education organisation. Health preservation was the leading principle of the approaches taken into account. The empiric research methods included content analysis, comparative analysis, synthesis and generalisation. The survey sampling and processing of experimental data were carried out by means of the hardware and software complex (HSC).Results and scientific novelty.The authors studied and documented the interconnection of students’ heart rate variability, taking into account their age and sex peculiarities, motion behaviour and medical groups. The regulatory systems tension degree differentiation was offered and approved. The criteria to determine a vegetative tonus of students (eutony, vagotony, sympathicotony) were identified on the basis of nonparametric algorithms of automatic classification, recognition of samples and theorem of statistical hypothesis tests. Thus, PE teacher can systematically increase the adaptation potential of students due to inclusion in a training course of corrective and rehabilitation programmes. The efficiency of IT in sport and recreational physical activities was scientifically based. The diagnostics on the basis of HSC, which includes data filtering, determination of parameters of selection of the histogram, graphic display of results of the spectrogram, allows specialists: to estimate the work of cardiovascular system and adaptatively compensation abilities of vegetative regulation mechanisms in a comprehensive, accurate and rapid way; to determine various violations of heart rhythm at donosological level (sick sinus node, atrial fibrillation, etc.); to select options for individual physical and training loads.Practical significance.The authors’ scientific and methodological approach to the organisation of sport activities raises the subject of PE in higher educational institutions to a significantly upgraded level: through computer technologies, it becomes the effective instrument of health-preserving activity, which is the promising direction in PE of student’s youth. The research results can be used in practice of educational institutions of various types.

Introduction. Today, the significant direction of scientific search in the field of health preservation is to study the interrelation of functional characteristics and motor skills of students of different constitutional types and health groups. Specific morphological and physiometric characteristics of an organism and belonging to a certain somatotype should be taken into account when organising physical training in higher education institutions.The aim of the research was to establish the degree of correlation of motor and functional characteristics of an organism of students with different constitutional types and health groups in order to improve an algorithm of planning and effective safe implementation process of physical training in a higher education institution.Methodology and research methods. Male-students (n = 1300) aged 17-20 years old of the 1st (n = 1012) and 2nd(n = 288) functional groups of health were examined. Constitutional types were determined according to M. V. Chernorutsky’s scheme with the calculation of values of Pignet index and Robinson index. Methods of the statistical analysis with the application of StatSoft Statistica 6.1 and Microsoft Excel programmes were used to process the obtained results in the process of diagnostics. The reliability of distinctions of average values was estimated by means of parametrical methods with the calculation of Student’s t-test.Results and scientific novelty. Motor features and functional characteristics of the cardiorespiratory system and physiometric parameters of firstand secondyear students (engaged in the programme of academic discipline “Elective Courses on Physical Culture and Sport” atIrkutskNationalResearchTechnicalUniversity) are recorded and considered. Reliable differences in the values of indicators of motor tests and functional characteristics of organisms of young people with different constitutional types are identified. In both health groups, the experiment allowed authors to reveal higher physical and functional preparedness of young men of normosthenic and asthenic constitutional types compared to their fellow hypersthenic students. Motor characteristics and functional reserve capacities of the cardiorespiratory system were higher in normosthenic and asthenic students of the 1st functional group in comparison with the representatives of the 2ndfunctional group of the same constitutional types. The conclusion is drawn on close interrelation of somatotypes with motor and functional characteristics of organisms of students engaged in physical culture.Practical significance. The research material and results contribute to the elaboration and development of the methodology of individually differentiated physical training of students in higher education institution.
