title: [The influence of the length of work on the adaptation of the circulatory system of male teachers of different specialities].
abstract: The problem of human adaptation to the social and biological conditions of the existence is placed at the center of attention of many natural and social sciences studying vital activity of a person in all forms it displays. The basis of the existence of the human population is considered to be a social and labor activity of people. Recently, the importance of researches has increased, which enables to evaluate the functional state of a person under the circumstances of adaptation to a particular occupation. These researches are the theoretical foundation to develop methods for improving the efficiency of people in many kinds of professions, and especially it is important for elderly people. The results of social and hygienic researches among the middle-aged and elderly people involved in different trades vary and are stipulated generally by the conditions of the working environment, difficulties and intensity of work processes. The study of the features of the circulatory system of a person in the process of working activities is a significant issue in physiology. It is found that the greatest changes in the functional parameters of the blood circulation are observed in young and elderly people. In the same way, it is shown that it depends on the type of adaptation, age characteristics, work experience which result in slowing down the rate of the processes of the nervous system, the regulation of blood circulation becomes inert, the level of physical health reduces, and age displacements accelerate. These changes are considered as a result of increased spending of physiological reserves of the organism in various environmental conditions.
