The article explores the use of digital models of hemodynamics to improve the health-saving competence of Physical Education teachers in postgraduate education through the integrative development of critical thinking and digital skills. The digital skills and critical thinking of a Physical Education teacher are relevant components of the 21 st century skills system and are components of the health competence of a Physical Education teacher whose improvement is an important educational condition for the implementation of the sustainable development concept. The use of digital hemodynamic models, together with dialogical maieutics, reflexive and interactive educational practices, is an effective innovative educational technology that promotes the integrative development of digital skills, critical thinking, and the formation of fundamental and practically oriented morphology-based knowledge of cardiovascular system. Formed digital skills, critical thinking and knowledge of cardiovascular morphophysiology in Physical Education teacher is presented as a personal and intellectual condition for the prevention of sudden cardiac death of children and other cardiac pathology in the educational process during physical activity. The results of the study confirm the effectiveness of the use of digital models of hemodynamics to improve the healthsaving competence of Physical Education teachers in postgraduate education through the integrative development of critical thinking and digital skills.

The article on the basis of the ecological value of reflection the concept of sustainable development and Hellenistic concepts is conceptual and methodological improvement of health saving competence of Physical Education teachers in the conditions of post-graduate education. There are presented methodological ways of greening of health and fitness technologies and identified opportunities for ecologically oriented their use by the teacher. Based on ecophilic interpretation of Hellenistic ideas are developed methodological concepts “Tellusantropo convergence” of the “Arete of the earth”, “Tellusantropo harmonization”, “Astoria of the Earth”, “Tellusantropo reflection”. Cultural, educational and technological sense of these concepts is existential axiological and ecophilic-oriented representation and interpretation the idea of sustainable development with the aim of using them as a Physical Education teacher in the educational health saving and fitness technologies and practices. In order to form a value relation to the Earth, to develop the “Arete of the Earth” and to unveil the “Existential of the Earth”, we used the value-oriented reflexive technique of the “Epistrophe of the Earth”. The method of “Epistrophe of the Earth” with its further improvement and testing can be used to form a valuable attitude to the Earth, actualization of environmental issues, formation of psychological health of participants in the educational process and actualization of the concept of sustainable development.

The article deals with the results of the research aimed at the improvement of methodology of use of augmented reality for the development of health preserving competence of a Physical Education teacher under conditions of post-graduate education. From the point of Umwelt phenomenology, augmented reality is characterized by correspondence to nature, its cognitive, metaphoric, diverse, interactive, anthropomorphic nature. The article analyzes the vectors of using augmented reality in the professional activity of a Physical Education teacher, particularly the one that is aimed at health preservation. The software that may be used with this purpose has been described. The attitude of Physical Education teachers to the use of the augmented reality for preserving their students’ health and development of their motion skills, intellect and creativity was determined in the research. The results of the survey show that the majority of teachers positively react to the idea of using augmented reality in their professional activity. However, in some cases, not a fully formed understanding of this issue was observed. The ways of solving the stated problem could be the inclusion of augmented technologies’ techniques into the process of post-graduate education, taking into consideration the anthropological, ethical, cultural contexts as well as teacher involvement in the stated process.

The article studies the results of the research aimed at the improvement of the methodology of develop- ment of the health-preserving competence of a Physical Education teacher in conditions of post-graduate education on the basis of Nikolai Bernstein’s theory of movement construction using virtual reality technologies. Based on the use of AR/VR technologies a software application “Virtual Model Illustrating Nikolai Bernstein’s Theory of Movement Construction” was developed. The stated model is one of the tools of the “Methodology of development of the health preserving competence of a Physical Educa- tion teacher on the basis of Nikolai Bernstein’s theory of the levels of movement construction”. The experimental study determines that the application of the virtual model within the stated methodology is an effective tool for the development of the health preserving competence of a Physical Education teacher. The application of the virtual model allows the actualization of the health preserving, conceptual, gnoseological, biomechanical, inclusive, corrective potentials of Nikolai Bernstein’s theory of movement construction. The use of the virtual model presents the ways of targeted and meaningful use of Nikolai Bernstein’s theory of the levels of movement construction by a Physical Education teacher and the improvement of physical and recreational technologies and concrete physical exercises and movement modes. Due to the application of virtual reality tools, health-preserving, preventative, corrective and developmental strategies are being formed among which the significant ones are: “Application of syner- gistic movements to adaptation to movement activity, and recreation”, “Application of spatial movements for actualization of the orientation and search activities and development of spatial thinking”, “Use of movements with a complicated algorithm for intellect development”.

The article presents the methodology of using knowledge about the phenomenon of heterochronia in pedagogy. The aim of the study is to improve the methodology of development of health-saving competence of Physical Education teacher in postgraduate education based on actualization and understanding of the phenomenon of heterochronia. The use of knowledge about the phenomenon of heterochronia is considered in the context of pedagogical anthropology and conducted within the framework of phenomenological, health-saving and anthropological approaches. Approaches used in the research are the following: competence, axiological, existential, transdisciplinary, etc. Due to the use of the phenomenon of heterochronia, the temporal phenomenology of a person is represented, as well as its non-linearity, processability. Knowledge of the phenomenon of heterochronia and its value interpretations is used in the pedagogical methodology of prevention of sudden cardiac death. The use of knowledge of heterochronia promotes the effective application of Physical Education teacher the knowledge of human morphophysiology in educational practices of health preservation and axiologicalization and humanization of the educational process. The results of the conducted study determine quite considerable prevalence of knowledge as well as value and health oriented understandings of heterochronia among the working Physical Education teachers in comparison with students mastering this profession.
