Basic indices parameters of the vegetative status in students of the cadet corps

Abstract

Introduction. Training in the cadet corps involves an increase in physical activity against a background of high informatization, which affects the autonomic nervous system’s functional capabilities and adaptation to stress. Materials and methods. The observation group consisted of 74 male students of the Cadet Corps (CC). The comparison group consisted of 26 boys aged 10-13 years who studied in a public secondary school (PSS). To evaluate the mode of physical activity, nutritional status, fitness, physical performance the authors performed bioimpedance analysis of body composition. The assessment of the vegetative status was carried out on the basis of the results of cardiointervalography with an active clinoorthostatic test. Results. Analysis of the personal data showed a great commitment to sports among the CC students. Cadets showed significantly higher values of the phase angle, active cellular and musculoskeletal mass, basic and specific metabolism. When recording cardiointervalography of rest in children of the observation group relative to the comparison group, statistically significant differences were revealed between the values of SDNN, RMSSD, variation range, vegetative balance index, rhythm vegetative index of physical exertion by 1.2-1.6 times. In 71.2% of cadets, the power of the heart rate variability spectrum corresponded to a high level. In children from the observation group, the initial vagotonia was recorded 2.2 times more often, and hypersympathicotonia - 7.0 times less often than in the comparison group. In the structure of autonomic reactivity in cadets, the hypersympathicotonic variant prevailed. Conclusion. The results of the analysis of the component composition of the body indicate sufficient fitness, physical activity and physical working capacity in CC students. The vegetative status of cadets is characterized by the predominance of the parasympathetic influence in the regulation of the heart rate. The hypersympathicotonic variant of autonomic reactivity indicates the exertion of adaptation processes to stress.
