Normal Respiration

Phonocardiograms were recorded in a population of normal children and adolescents (116 subjects) in order to evaluate variables which might affect splitting of the second heart sound. Tracings were recorded during normal respiration in supine and sitting positions. Position was the major variable affecting splitting. Eighty-five percent of this population exhibited greater variation in splitting when sitting than while supine. In the remainder of the subjects, the splitting variation was greater in the supine position. Heart rate, sex, age, height, and weight had little or no effect on the splitting pattern of the second sound; 15% of the subjects exhibited fixed splitting of the second sound in either, but not both, the supine and upright positions. This was defined as less than 10 msec variation in splitting during normal respiration. This observation indicates the necessity of assessing the second sound in both supine and upright positions before a judgment is made concerning the existence of an abnormal splitting pattern.

Exercise Interventions

Background: Childhood obesity has negative impact on heart-rate variability (HRV) and, thereby, on the cardiovascular health of children and adolescents. Thus, physical-exercise interventions were proposed to increase HRV. The present systematic review aims to provide an up-to-date analysis of research on the effect of physical-exercise interventions on HRV in obese children and adolescents. Methods: An electronic search of the literature was performed, and 10 articles were included. PRISMA guideline methodology was employed. Results: Physical-exercise interventions predominantly involved aerobic training; however, alternative training programs, including judo or recreational soccer, were found. The duration of intervention ranged from 6 to 24 weeks, with a training frequency of between 2 and 7 times per week. The duration of sessions typically ranged from 40 to 60 min. Conclusions: Results of the included articles indicated that physical-exercise intervention increased the HRV and thereby the autonomic modulation of obese children and adolescents. This is significant, as HRV is associated with cardiovascular health. Such physical-exercise interventions are crucial to reduce weight and improve cardiovascular health in children and adolescents, thereby achieving a sustainable future.

Objective. To evaluate the effectiveness of psychophysical training as a method of non-drug correction of vegetative dystonia syndrome of sympaticotonic type and primary arterial hypertension in children and adolescents. Material and methods. 164 patients aged 717 years with sympathicotonic vegetative dystonia syndrome were examined, of which 47 were diagnosed primary arterial hypertension. The baseline autonomic tone (by cumulative clinical tables of autonomic manifestations), autonomic reactivity (based on the results of variation pulsography in ortho-and clean position), support activities (by clean orthostatic test) were evaluated, the heart rate variability was analyzed. As a method of non-drug correction of the functional state of the autonomic nervous system, psychophysical training (main group, n = 110) and therapeutic physical culture (comparison group, n = 54) were used. To assess the effectiveness of treatment, patients were examined twice: before and after the course. Results. It was found that in the sympaticotonic type of vegetative system, excessive vegetative reactivity and activity maintenance predominate. The use of psychophysical training leads to their normalization in most patients. In patients with primary arterial hypertension, the level of blood pressure decreases. According to the analysis of heart rate variability in the main group there is a significant increase in the total power spectrum of neurohumoral regulation, representation of high-frequency fluctuations with simultaneous reduction of the share of low-frequency waves as well as aligned sympathetic-parasympathetic balance. Conclusion. Psychophysical training is an effective method for non-drug correction of vegetative dystonia syndrome by sympaticotonic type and primary arterial hypertension in children and adolescents.
