Relevance. This work is devoted to social diagnostics and social prevention of possible negative side effects of medical, social and psychological plan that occur against the background of the main training and educational processes of pubertal athletes, taking into account their gender.
 Purpose: to assess the gender characteristics of the life quality and personal anxiety (PA) dynamics of the Brothers Samurgashevs’ Rostov Region Olympic Reserve Sports School No. 35 high school students against the background of classes at the health school (HS).
 Methods: historical, pedagogical, socio-psychological, social prevention, sociological, statistical and graphic methods, as well as the method of content analysis.
 Results: after the HS classes PA decreased more than 40% overall for the sample. The decrease in PA was accompanied by an increase in QoL by almost 15%. The main PA priorities for female athletes turned out to be the following signs: “You are in danger of failure, bad luck”; “To see bad or “prophetic” dreams”; “Something is not working out for you”. Among male athletes, the initial level of PA was lower than that of female by 40.1%. The priorities of male anxiety were such signs as: “You are in danger of failure, bad luck”; “They don’t pay attention to you”; “You can’t do your homework”. After HS classes, girls most quickly eliminated PA in such areas as “Waiting for parents after their personal conversation with the school principal” and “Seeing bad or “prophetic” dreams”, and boys - “You don’t understand the teacher’s explanations”, “(They) fell silent when you approached”, “Something is not working out for you”. The initial level of QoL of young female athletes was significantly lower by 8.7% than that of young male athletes, and after training at the HS, it exceeded the corresponding indicator in the group of young male athletes by 4.7%. After classes at the HS, young male athletes noted an improvement in relations during their studies (with peers, superiors, etc.), however, in quantitative terms, this improvement was 9 times lower than in the group of young female athletes. Also, young male athletes noted an improvement in their physical condition and strengthening of skills and abilities in organizing their time, but 5 and 4 times (respectively) less pronounced than in the group of young female athletes.
 Conclusion. The results obtained can be widely disseminated in similar sports schools to ensure monitoring and bringing the level of personal anxiety and quality of life of students to age norms.
