Modern science is actively studying developmental disorders in preschool children with mental retardation. Many mechanisms for the formation of mental retardation in preschoolers have been elucidated. It is recognized that the preschool age is most favorable for the successful correction of the development of such children. Considering that the general development is directly related to the level of speech formation and the mental activity, it was decided to evaluate the corrective possibilities of logorhythmics in children with mental retardation. To assess the developmental characteristics of such children, a set of complementary research methods was applied in dynamics. It includes: the “House” method, the method of studying the sound-absorbing side of speech, the method of studying attention “Find the difference”, the method of studying thinking “Understanding pictures with hidden meaning”, the method of researching the level of vocabulary development and general awareness “Show and tell”. The author’s logorithmic correctional program showed its advantages in comparison with the traditional correction in relation to the development of personal, intellectual and speech development in children with mental retardation. This was confirmed during the comparison of the results of correction in the experimental and control groups, which proved that logopedic rhythmics is the preferred means of enhancing development in preschool children with mental retardation.

Posture deformation occurs under the influence of factors that violate the vertical position of the spine. When the load on the spine is redistributed, the position of the body is adjusted by selective training of the muscles of the trunk and changing the position of the pelvis in the frontal plane. Exercises for impaired posture should be aimed primarily at preventing progression and correcting curvature and twisting of the vertebrae. It is important not only the correction of curvature, but also the stabilization of the spine in a corrected position. Saving the achieved results contributes to the formation of a new static-dynamic stereotype of the spine. This is possible by deliberately influencing the upper and lower in relation to the main curvature of the links of the musculoskeletal system and muscle tone-regulating groups involved in posture formation.

An important element of the human musculoskeletal system is the hip joint, it has a complex structure. The hip joint is very vulnerable and can sometimes be severely affected. Injuries, degenerative processes in cartilage, and excessive physical exertion create conditions for destructive changes in the structures of the hip joint. Degenerative-dystrophic changes in the structure of the joint form the need for endoprosthetics. After endoprosthetics, a complex rehabilitation process is needed, which should be based on regular dosed physical exercises, which do not allow weakening the muscles, which provide movement in it, and rationally combine them with massage and hydro-procedures. In this way, it is possible to return the optimal motor ability of the limb after hip joint arthroplasty and to ensure a person’s return to his normal life. Improving the efficiency of recovery after hip arthroplasty can be continued with further research in this direction.

Youth’s health is currently considered at the level of universities: various programs and projects are implemented; teaching aids and methodological recommendations are introduced into the educational process. All this requires the development and use of new educational technologies to form the values-based attitude of students to their health. Due to the COVID-19 outbreak, the heads of many universities had to make a difficult decision to suspend the educational activities of their students, which requires quick adaptation to the new conditions. The study aims at determining the readiness of students to form physical activity-related health competence in the course of distance learning. The article provides an experimental assessment of students' readiness to form the physical activity-related health competence in the course of distance learning. The lack of it stipulates the need to determine specific activities to improve distance learning in physical education and sports. Consequently, the current need is to form the physical activity-related health competence of students, which ensures the improvement of their health and the possibility of realizing their potential abilities in the learning process.
