16-18 year-old cadets' somatic and vestibular autonomic reactions at marine educational institutions depending on the age and physical preparedness

Specific requirements for individual characteristics of future specialists is the difficulty level of professional activity, determined by the degree of the aggregate effect on the body of all factors making working conditions. In many professions, especially in specialized and related to the process of movement in space as a pilot, a driver, a sailor and etc.., great importance is the vestibular apparatus, which is the informant about gravity vertical position when moving the body, providing a body orientation of muscle tone and redeployment. at the same time, during stimulation of the vestibular apparatus with straight linear and angular acceleration observed changes in the autonomic, sensory and motor reactions of the organism. The study of relations between the vestibular and cardiovascular systems, and between the vestibular and somatic reactions, the duration and severity making changes, are important to assess the general state and the degree of readiness for the chosen specialty. in this connection the purpose of this study was the study of somatic and vestibular autonomic reactions among students who are future workers of marine specialties with different levels of physical preparedness and aged from 16 to 19 years old. The study found, that the standard vestibular loads cause noticeable somatic and autonomic reactions and do not depend on their age characteristics and level of physical preparedness. This is evidenced by, on the one hand, no significant differences in indicators " time of indecision" and HR among cadets of 16-19 years old of various training stages after the standard vestibular loads, on the other hand - a significant difference between the level of physical preparedness among the cadets of the studied groups.
