Problem formulation The importance of health in the system of universal values is associated with its status as a fundamental basis for the optimal implementation of each individual’s abilities and potential [1, 3, 17]. Therefore, in the current context of reforms in Ukraine, the health of its population is recognized as a component of national development, which serves as a determinant of the range of tasks in the state-declared social program [12, 13, 14]. Under modern conditions the health state of adult Ukrainians in general and children and youth in particular is an unprecedented challenge to society and the state, and thus clearly poses a threat to humanitarian security of Ukraine [5, 6, 8]. This emphasizes the expediency of paying more attention to ensuring adequate motor activity as a condition for improving health, maintaining efficiency and promoting the diverse development of Ukrainian population, including students [4, 9]. Analysis of recent research and publications Based on the systematization and generalization of sources devoted to the research issue [7, 10, 11], it is obvious that the physique is one of the parameters of physical development, which allows to gain an objective idea of the spatial organization of human body morphological components, constitutional features of its body, proportions, etc. It is also known that the physique is characterized by individual gender and age characteristics, which gives grounds to position it in the systemic dimension as an interdetermined and interrelated spectrum of human body morphofunctional components [14, 15]. Sublimation of advanced scientific ideas into the strategy of student youth’s rehabilitation involves the creation and implementation of effective innovative technologies. At the present stage of the field of physical culture and sports development, health fitness systems are recognized the most in terms of body correction effectiveness means [15]. In this context, it should be noted that within current transformation of physical education paradigm, which is related to clarifying the range of interests and needs of students related to their physical and spiritual improvement [],the issues of female students’ physique correction remain unresolved taking into account the peculiarities of their body mass geometry. As a result of a thorough study of the professional specialized literature, it has been established that the term "mass geometry" was introduced into scientific circulation by the Frenchman Anton de la Guerre in 1857 [2]. Digression into the history of formation and interpretation of “mass geometry” concept has made it possible to state that today the geometry of body mass is interpreted as a concept which outlines the distribution of human body biolinks in space relative to somatic frame of reference, it includes data on the location of the body general center of mass (GMC), moments of inertia of body biolinks according to their planes and axes of rotation, ellipsoids of inertia and a number of other indicators [2]. Dynamics of geometry indicators of students’ body mass in the process of their physical training under the influence of author’s technology 47 The scientific and methodological dimension of the relevance of this work is determined by the inconsistency between the need to correct the physique of female students given the peculiarities of their body geometry and improper methodological development of physical fitness means, used during physical training, which in its turn allows effective solution of the declared problem. The study has been performed in accordance with the 2018 – 2023 Research plan of the Lesia Ukrainka East European National University on the topic “Modern technologies for formation and maintenance of health for various population groups by means of health-improving physical activity”, state registration number is 0118U004196. Objective The experiment has involved 121 female students aged 17–18 with different body types, among which: mesomorphs – 64 females, ectomorphs – 35 ones, endomorphs – 22 individuals (n = 121). Methods and organization of the study Completion of the tasks set in the dissertation involves a set of methods, namely: theoretical ones are used to study and substantiate the basic provisions of the study, outline its problem field, systematize the experience of scientists on the correction of female students’ physique in the process of physical training, development of modern scientific approaches to development and improvement of physical education; empirical methods include pedagogical observation as a method of empirical level of research that helps get acquainted with the process of organizing physical education at Department of Physical Education at Kyiv National Economic University named after V. Hetman; anthropometric examination of female students with the use of standard tools (the examination has presupposed the use of a reference point when measuring anthropometric points with a very specific localization in relation to the selected skeletal bone formations, and for more accurate measurement – the use of somatic coordinate axis. The location of an anthropometric point has been determined based on palpation, painless pressing, and then further marking it with a demographic pencil; defining students’ body type has been provided by using the Pinier index. Method of recording and analysis of static-dynamic stability of the female students body (diagnostic and training complex “SportKat 650 TS” on the basis of a mobile platform, the degree of mobility is adjustable), pedagogical experiment – consistently transforming, statistical methods – to process the results of the study, to determine the statistical significance of the results. Experimental data have been processed using conventional methods of mathematical statistics based on the calculation of averages ( ); standard quadratic deviations (S); errors of representativeness (m). In establishing the statistical significance of the differences between the sample indicators, the distribution of which did not comply with the normal law, nonparametric criteria have been used: for independent samples – Mann-Whitney U-test has been applied, for dependent samples Wilcoxon criterion has been applied [16]. All calculations required the use of computer software STATISTICA 7, Statista 6.0, offered by Microsoft, Statsoft. The study was conducted during years 2018 – 2019 on the basis of Department on Physical Education, KNEU named after Vadym Hetman. x 48 Viktoriia Matiichuk, Tamara Khabynets, Leonid Yarmolinsky The technology of female students’ physique correction, substantiated taking into account their body mass geometry in the course of physical training, is aimed at achievement of the corresponding purpose by observance of system, normative-target, personality-oriented approaches. The structure of the technology has contained the purpose, tasks, principles, pedagogical conditions, stages, namely organizational- introductory, correctional-preventive, supportive ones. The peculiarity of the suggested technology is the correctional and preventive direction reflected in the developed class- studio “Grace”, which includes “Studio of postural disorders prevention”, “Studio of static-dynamic stability” and “Correctional studio”. Based on the content and structure of the author's technology, the criteria of its effectiveness are outlined, which determine the degree of its effectiveness in the process of female students’ physical training. Results The technology previously developed and presented by us was further tested during a consistent transformation experiment, in particular during its implementation in the process of physical education for 17 – 18 year old female students. The positive effect of the suggested technology is evidenced by changes in the average values of circumferential body size among female students of mesomorphic body type: increase in average values of the chest girth ( ; S) (before: 85.3; 5.50 cm after: 88.2; 4.71 cm), (p <0.01); increase in average values of shoulder girth (before: 26.2; 3.81 cm after: 27.7; 2.19 cm), (p <0.01); decrease in the average values of the circumferential abdomen size (before: 68.1; 5.51 cm after: 66.3; 3.32 cm), (p <0.05); decrease in the average values of thigh girth (before: 55.0; 3.80 cm after: 53.9; 2.00 cm), (p <0.05). Statistically significant changes have been found regarding the increase of average values of circumferential shoulder size among students of ectomorphic body type: ( ; S) (before: 23.3; 3.71 cm after: 24.9; 2.21 cm), (p <0.05); average values of thigh girth (before: 52.1; 4.94 cm after: 53.9; 2.01 cm), (p <0.05). During the examination of female students that belong to endomorphic body type, we have also noticed an improvement (decrease), namely: the average values of the circumferential abdomen size ( ; S) (before: 75.4; 4.83 cm after: 72.1; 2.95 cm), (p <0 , 05) and the average values of hip circumference (before: 58.3; 4.25 cm after: 56.2; 2.19 cm), (p <0.05). Analysing the results of tests aimed at performing motor tasks with more active body movements, in particular “Dynamic test – clockwise movement”, it has been found out that 17 – 18 year old girls who participated in the study had some difficulties in implementation of these movements. The subjects of the experiment could not clearly display or get as close as possible to the desired result of the movement, which is set by the software “Sport Kat 650 TS”. In particular, it is necessary to repeat the trajectory of the point movement (circle shape; direction of movement clockwise or anticlockwise), the movement of which is displayed on the monitor screen, controlling the position of the body pressure centre (PC) on a movable support (platform), the movement of which is also shown on the monitor screen. However, a certain tendency has been established, according to which the results of tests are the worst for 17 – 18 year old girls of endomorphic body type comparing to other experimental groups. Particularly, in fig. 1 it can be seen that the experimental group is characterized by a rather chaotic movement of their body PC with corresponding, rather Dynamics of geometry indicators of students’ body mass in the process of their physical training under the influence of author’s technology 49 sharp, changes of motion due to macro-oscillations, which leads to a corresponding shape of the trajectory of the body PC on a moving support. Fig. 1: Examples of test results, performed on the diagnostic and training complex “Sport Kat 650 TS” by 17 – 18 year old girls of endomorphic body type: “Dynamic test – clockwise movement” Among 17 – 18 year old girls of ectomorphic and mesomorphic body types during the performance of these tests, the shape of the trajectory of the body PC is closer to the specified, although the nature of the movement should be associated with quite sharp changes in direction and macro-oscillations. It is an interesting fact that a common feature of the two groups is that during performing “Dynamic test – clockwise” the trajectory of the body PC, as a rule, is similar to an ellipse in its shape in which the anterior-left and posterior right traffic area prevail. The available factual material allows noting that when conditions of exercises performance are complicated (it refers to test tasks), 17 – 18 year old girls of endomorphic body type have worse results in contrast to 17 – 18 year old girls of mesomorphic and ectomorphic body types. It is likely that increased body weight negatively affects the completion of more complex test exercises.
