[Characteristics of heart rate variability in healthy adolescents and male adults].

The primary purpose of the present article is to investigate the comparative characteristics of heart rate variability in healthy adolescents and male adults. The study was carried out on 41 male adolescents aged 15-16 years and 73 male adults aged 18-22 years. For assessment of heart rate variability statistical data of variability and spectral analysis of heart rate were estimated. Achieved results have proved once again that vegetative balance in healthy individuals is not identical that can be explained by various physiological processes of adolescent age. Such start conditions probably may affect the character of body response to different stimulative impacts. The study suggests that adults tend to have the prevalence of sympatic regular mechanisms whereas in mature age the cases of individuals with the balanced vegetative nervous system in quiescent mode without pathologies are much more frequent.
