Abstract
The article presents the study of 105 healthy young men 18 - 25 years. The aim of the study is to assess the state of autonomic regulation of sinus heart rhythm in young men: conscripts, students and cadets. Methods: the therapeutic examination, Vein Questionnaire, asthenic scale, hospital anxiety and depression scale HADS, and visual analogue pain scale, high - resolution rhythmocardiography at rest and mixed autonomic stress testing. Results: rhythmocardiography at rest showed longer RR - intervals in the group of cadets, which testifies to their greater physical aptitude. Among conscripts significantly lower heart rate variability and amplitude of respiratory arrhythmia at rest and in the Valsalva - Burker maneuver. Students showed more scores on the anxiety and depression scales, more symptoms of asthenia and autonomic dysfunction, headache and back pain. Cadets had no disorders of psycho - emotional and autonomic status, rhythmocardiography showed a high level of physical fitness and good adaptive capacity.
