Aim. The article aims to study the dynamics of the adipose tissue hormone leptin in healthy females with different body component composition and body mass index to assess their energy status under stress. Materials and methods. Based on anthropometry and bioimpedancemetry, three groups of girls were formed: the first group included girls with a BMI of less than 18.5 kg/m2, body mass deficiency (BMD), the second – from 18.5 to 24.9 kg/m2, normal body mass (NBM), the third – with a BMI of more than 24.9 kg/m2, which corresponds to overweight (OvBM). The body component composition was determined by bioimpedancemetry. Plasma leptin concentration was evaluated by enzyme-linked immunosorbent assay both in normal conditions and during emotional stress. Results. In the selected subgroups, a significant difference in the body component composition was found with an increase in the series of BMD → NBM → OvBM. When assessing the level of metabolic processes by the magnitude of the phase angle, it was found that 3.41% of females with BMD showed signs of increased protein catabolism. The stress-induced dynamics of the hormone leptin was evaluated. In normal conditions, the concentration of leptin in blood plasma positively correlated with BMI and depended on the component composition of the body. Conclusion. In persons with BMD, the adipose tissue hormone leptin had a negative dynamics under stress conditions, which was an adequate adaptive physiological response to stress. Females with BMD had a significantly high positive dynamics of leptin, while girls with OvBM did not have significant changes in its concentrations, which can be explained by the development of leptin resistance.

Objective: to determine a component body composition of students specializing in volleyball and athletics and to conduct a comparative analysis of the results.Materials and methods: the study was conducted at the Department of physical training and sports at the Yaroslavl State Medical University of the Ministry of Health of the Russian Federation. The study included students from different groups of physical training: volleyball (10 men and 10 women), athletics (10 women) (experimental groups), and firstyear students that attended physical training classes (14 men and 16 women) (control group).Results: significant differences were revealed between the anthropometric measurements in the experimental groups of the studied women and between the results of anthropometric measurements in the female volleyball players, female athletes, and students from the control group. Significant differences were revealed in the component body composition of the studied women from the experimental and control groups. The analysis of the results of anthropometric measurements in the experimental and control groups of men did not reveal any significant differences between the parameters. Bioimpedancemetry revealed significant differences in the composition of the internal milieu of volleyball players in comparison with the control group.Conclusions: 1. differences were revealed in the component composition of the body of female athletes involved in gamebased and cyclic kinds of sport as well as in the parameters of bioimpedance of female volleyball players and the control group. Female volleyball players had higher parameters of total body fluids, intracellular and extracellular fluids, fatfree, fat, and active cell mass in comparison with female light athletes and the control group. The differences in the obtained results were more significant in the experimental groups. 2. Bioimpendance analysis of men showed significant differences in the component body composition of volleyball players in comparison with untrained students. The parameters of total body fluids, fatfree, fat, and active cell mass in sportsmen exceeded the same parameters in the control group. 3. Differences were established in the anthropometric parameters depending on the sportoriented specialization of female students. Female volleyball players had higher values of mass, length, body weight index, and body surface area, the circumferences of the pelvis, thighs, and wrists in comparison with the results obtained in female light athletes. Similar differences were revealed in the anthropometric parameters of female volleyball players and students from the control group. Significantly lower values of the body weight index, circumference of the chest and pelvis of female athletes were registered in comparison with students from the control group. Male volleyball players did not have significant differences in the anthropometric parameters. They tended to have an increase in the body mass, length and surface area of the body, circumference of the chest, thighs, and wrists.

Purpose of the study: the aim of that study was an investigation of the level of adipokines, myokines and growth factors in the blood of athletes involved in acyclic sports — martial arts.Materials and methods: we have investigated 15 male athletes aged 15–19 years. The control group included 15 healthy men of the same age who did not engage in sports. In the blood serum of the all subjects, leptin, adiponectin, resistin, apelin, irisin, adipsin, myostatin, FGF21, osteocrin and oncostatin were determined using a multiplex analysis.Results: studies have shown that long-term regular martial arts training is accompanied by a decrease in the level of leptin, resistin and oncostatin M in the blood of athletes and a change in correlations between the content of the studied myokines, adipokines and growth factors compared with their values in the control group.Conclusions: regular long-term martial arts training is accompanied by a decrease in the level of leptin, resistin and oncostatin M in the blood of athletes. Their occurrence is associated with changes in the state of regulatory systems that control the production and secretion of myokines, adipokines and growth factors in adipose, muscle, nervous and bone tissue. The resulting shifts ensure adaptation of the athletes’ bodies to physical activity.
