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 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.

The article presents the methodology and methods of improving the health-preserving competence of a Physical Education teacher under conditions of postgraduate education based on the knowledge of prevention of acute bronchitis, COVID-19 influenza and acute respiratory diseases. The “Disciplinary and methodological matrix of health-preserving competence of a Physical Education teacher” is used, which includes such developed “integrated disciplines” as Pathopedagogy, Propaedeutics of Health and Health Therapy. The matrix is aimed at professionalisation, methodologisation, technologisation, anthropologisation, axiologisation of the health-preserving competence of a teacher. The “Methodology of developing health-preserving competence of a Physical Education teacher based on the knowledge of prevention of acute bronchitis, influenza and acute respiratory diseases” is used. The methodology is based on the competence approach, the above-mentioned matrix, problem-based and flipped learning, andragogy, game, maieutic and dialogic methods, the use of pedagogical tasks, the Hellenistic concept of "self-care" and others. In this methodology, knowledge, values and practical health-preserving strategies are hierarchised with the singling out of three levels – A, B and C. Level A is obligatory, and levels B and C are given less attention. An experimental study was conducted the result of which determined the effectiveness of this method. These methodology and method are humanistic and ecocentric and consistent with the ideas and sustainable development goals.
