The paper addresses relations between the characteristics of body composition in international sprint swimmers and sprint performance. The research included 82 swimmers of international level (N = 46 male and N = 36 female athletes) from 8 countries. We measured body composition using multifrequency bioelectrical impedance methods with “InBody 720” device. In the case of male swimmers, it was established that the most important statistically significant correlation with sprint performance is seen in variables, which define the quantitative relationship between their fat and muscle with the contractile potential of the body (Protein-Fat Index, r = 0.392, p = 0.007; Index of Body Composition, r = 0.392, p = 0.007; Percent of Skeletal Muscle Mass, r = 0.392, p = 0.016). In the case of female athletes, statistically significant relations with sprint performance were established for variables that define the absolute and relative amount of a contractile component in the body, but also with the variables that define the structure of body fat characteristics (Percent of Skeletal Muscle Mass, r = 0.732, p = 0.000; Free Fat Mass, r = 0.702, p = 0.000; Fat Mass Index, r = −0.642, p = 0.000; Percent of Body Fat, r = −0.621, p = 0.000). Using Multiple Regression Analysis, we managed to predict swimming performance of sprint swimmers with the help of body composition variables, where the models defined explained 35.1 and 75.1% of the mutual variability of performance, for male and female swimmers, respectively. This data clearly demonstrate the importance of body composition control in sprint swimmers as a valuable method for monitoring the efficiency of body adaptation to training process in order to optimize competitive performance.

Aim. The article deals with justifying theoretically and describing the authors’ methods of mental health maintenance in teachers experiencing emotional stress. Materials and methods. The proposed methods of mental health maintenance in teachers are based on the ideas of psychosomatics (S. Freud and I. Malkina-Pykh) and non-directive psychotherapy (C. Rogers). Three groups of methods have been described: self-analysis of a current life situation, energy recovery in teachers, and self-regulation of emotions in group interaction. Results. The authors studied neuro-psychological stress in teachers using Nemchin’s method. At the summative stage of the experiment, it was established that 56% of teachers experienced high neuro-psychological stress, and 26% – average. In 2018, the methods described were implemented at one of the comprehensive schools of the Russian Federation. The results of control diagnostics demonstrate a significant decrease in neuro-psychological stress in teachers who implemented these methods of mental health maintenance. This proves the effectiveness of the solutions proposed. Conclusion. This article contributes to the theoretical data on mental health maintenance in modern teachers. The scientific novelty and practical importance of this study are connected with the developed methods of mental health maintenance in teachers. The methods proposed can be used in practice for improving teachers’ expertise both in Russia and abroad.
