The purpose of the study is to make a comparative analysis of occupational therapy models based on Person-Environment-Occupation-Performance Model, Canadian Model of Occupational Performance, and competent environmental activities (Care of People with dementia in their Environments), as well as to provide a brief historical review of the development and formation of models in occupational therapy. Materials and methods. The main research method is the method of analysis, which is used to comprehensively consider and describe the historical development, comparison and using activity-oriented models in occupational therapy. Results and discussion. Selecting more effective activity-oriented models requires comparing occupation models, making recommendations for selecting and combining these models in practice, and providing a systematic approach to integrating occupational engagement models with reference systems for guidance, evaluation, and intervention. All models follow a common line of thinking, and this reinforces theories. The choice of model to be used to support the practice will ultimately depend on the therapist's knowledge. Understanding these models will provide the therapist with the knowledge to view the individual as a person and to guide the therapist to clinical considerations. Models are not identified with a specific group of customers, but Canadian Model of Occupational Performance is suitable for situations where a client-oriented approach is required. The Care of People with dementia in their Environments model with a flexible approach will support the therapist's reasoning in situations where clients are unable to solve the problem or the therapist requires more guidance. It is worth noting that at the moment, a very popular practice, which is focused primarily on the client, is the basis for interaction with people in all countries. During occupational therapy, the therapist should move smoothly from one section to another to provide adjustment and improvement. In fact, success in occupational therapy is seen as an important element, because it is believed that it increases self-esteem and motivation to accept new challenges. Conclusion. The analysed models of occupational therapy are based on humanistic values, indicating that occupational therapy distinguishes classes as a positive interaction between man and the environment to influence the general well-being. All three discussed models provide a clear structure of the occupational therapy process. The practical value of the research in this area is to identify and explain opportunities for the most effective use of occupation-focused models

Мета: дослідити біологічний вік спортсменів та студентів, які не займаються спортом. Здійснити порівняльний аналіз темпів старіння у представників обох груп. Матеріал і методи: вибірка складалася з 58 студентів юнаків: спортсменів (n=28) у віці 18-20 років і студентів, які не займаються спортом (n=30) у віці 18-20 років. Групу спортсменів представляли студенти футболісти, які були членами збірної команди університету з футболу та фут залу. Всі спортсмени мали спортивну кваліфікацію від першого дорослого розряду до КМС. Порівняння проводилося з групою студентів, які не займалися спортом, окрім занять з фізичного виховання. Біологічний вік визначався за методикою В.П. Войтенка (1991 р.). Результати: встановлено, що біологічний вік обстежуваних спортсменів за середнім показником складає 23,44 років (δ=3,77), тоді як у студентів, які не займаються спортом 38,82 (δ=4,65). За абсолютним показником різниця становить 4,54 років у спортсменів і 20,32 у студентів, які не займаються спортом. За відносним показником біологічний вік юнаків-футболістів на 12, 4 % перевищує паспортний. У юнаків, які не займаються спортом різниця між біологічним та паспортним віком становить 110,98 %. Висновки: темп вікових змін у спортсменів  уповільнений,  у студентів, які не займаються спортом – прискорений. Це зумовлено більшою кількістю шкідливих звичок, низьким рівнем рухової активності. Таким студентам рекомендується дотримуватись правил здорового способу життя, активний відпочинок, заняття фізичними вправами, спортом.

The purpose of the study is to define aspects of the patient's participation in the rehabilitation process and to define a conceptualization that improves the participation of the client. Materials and methods. The main research method is the method of analysis, which has been used to comprehensively review and evaluate the participation of the client in the rehabilitation process and an overall assessment of the structure that could improve the participation of the client. Results and discussion. One of the goals of the world community development is to preserve and strengthen human physical, social, mental and spiritual health. However, humanity has faced global environmental, economic, social and moral problems. The genetic burden of mankind, the ecological crisis, natural disasters and man-made disasters, wars and local conflicts and social instability lead to an increase in the need for rehabilitation. Therefore, in recent decades, the role of both the client and relatives in the rehabilitation process has changed, taking into account the participation of the client. In this paper, we consider the process of rehabilitation taking into account the participation of the client, as a variant of the client-oriented structure, the Canadian Occupational Performance Measure is evaluated primarily from the point of view of clients, occupational therapists and members of the rehabilitation team. The main goal is to maximize the participation of patients in the rehabilitation process. The emphasis of the occupational therapist is on the participation of the patient in determining outcomes and goals. Through years of practice and experience, occupational therapists have developed a model for client-centered practice in occupational therapy, namely the Canadian Model of Occupational Performance. And the result of using this model is the development of the Canadian Occupational Performance Measure, which has become a good tool for obtaining a result based on the client’s perception. Conclusion. Implementing a customer-centric approach is easier when a structured approach is used, but this is not enough. Participation and motivation of all team members are required, as well as support during the implementation period. Management support, knowledge of the underlying theory, time for discussion and reflection, as well as the opportunity to develop a personal interview technique, which indicates important factors for successful implementation, are also required
