Abstract:

34 persons aged 18-22 have been examined in order to compare the serum levels of hormones ghrelin and leptin in the morning in a fasted state and 15 and 45 minutes after consuming a standard breakfast of protein (100 g of meat in the form of burgers and 200 ml unsweetened tea) at rest and after a situation of emotional stress. Taking into account the initial tone of the autonomic nervous system and mathematical analysis of the heart rate variability, all the examinees were divided into three groups: normotonics, vagotonics and simpatotoniks. We stated that predominance of the parasympathetic or sympathetic nervous system tone implies differences in the content of ghrelin and leptin levels at rest and after the joint influence of a protein breakfast and emotional stress. A significant increase in the concentration of leptin after protein breakfast and emotional stress is characteristic of simpatotoniks, and increasing concentrations of ghrelin in the 45th minute were found in vagotonics.
