However, empirical research is lacking to analyze the characteristics of prosocial sport behavior among Russian athletes. The aim of the study - to identify relation between athletes' focus on moral standards, social values of sport and prosocial behavior and their psychological resistance and psychological well-being.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;The research studied 174 athletes, including team (game-based) sports (volleyball, basketball, football: 53.5%), and individual (cyclic) sports (track-and-field athletics, skiing, swimming: 46.5%); age from 17 to 28 years (mean: 20); 42% are men, 58% are women; sports experience from 1 to 19 years (mean: 8.5); 18% are Masters of Sports and Candidates Master of Sports, 16% have athletic titles, 66% do not have athletic titles. The following methods were used to conduct the study: Psychological Competence of Athletes, Subjective Well-Being Scale (Russian-language version by M.V. Sokolova), Moral Foundations Questionnaire (MFQ-32), Spirit of Sport (SOS) (Russian-language version by K.A. Bochaver), Prosocial and Antisocial Behavior in Sports Scale (PABSS - Prosocial and Antisocial Behavior in Sports Scale; Russian-language version by P.A. Kislyakov et al.).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;In general, all sports values at an above-average level are important to the test-takers, however, the values of teamwork and solidarity are less in demand. Athletes are more likely to point to the examples of how they demonstrate help and support to others during competitive activities and workout training than examples of unsportsmanlike and aggressive behavior. At the same time, prosocial sports behavior is more often observed with respect to the teammates or the national team. The study results made it possible to establish correlations between the prosociality of athletes, the importance of moral standards, social sport values (respect for sports ethics, adherence to rules, teamwork, respect for oneself and for other participants of competitions, good manners and education, a sense of community and solidarity, health), psychological sport resistance and subjective well-being. At the same time, prosociality in sports is a predictor of psychological resistance and subjective well-being.

This review aims to provide a comprehensive summary of the current understanding of ASI, covering its anatomy, etiology, the influence of psychosocial factors and primarily focusing on management strategies. The management of ASI is a central focus for restoring normal biomechanical and anatomical function of the injured upper extremity. A literature review was conducted, seeking to further understand the current treatment approaches of this condition. The management of ASI employs differing combinations of physiotherapy, rehabilitation and surgery, with treatment dictated by patient stratification models and patient reported outcome measures (PROMs). Clinical stratification of patients along a diagnostic continuum aid devising appropriate patient-centered treatment and is based on the extent of anatomical disruption. Exercise-focused therapy, particularly the Watson Instability Program, is highlighted as a promising approach, emphasizing scapular and rotator cuff muscle strengthening to restore active shoulder control. Surgical interventions, such as open inferior capsular shift, arthroscopic capsular plication, and electrothermal arthroscopic capsulorrhaphy, are discussed in detail, with emphasis on their indications, outcomes, and comparative effectiveness. We also shed a light on the psychosocial factors role in ASI management outcomes, underscoring the importance of a multidisciplinary approach in patient care. In summary, ASI management necessitates a holistic approach that integrates anatomical understanding, tailored treatment protocols, and consideration of psychosocial factors.
