The purpose of the study is to identify self-reliance manifestation features among qualified athletes of different sports. Material and methods. The study participants were representatives of combat sports (boxing) n = 23, complex-coordination (gymnastics) n = 25, speed-strength (discus throw) n = 23, and also cyclic sports (swimming) n = 38. In total 109 sportsmen. The age of the respondents was from 16 to 18 years old. Comprehensive psycho-diagnostic methods diagnose self-reliance level and manifestation degree of athletes’ personal qualities. Results. The results of the study confirmed our hypothesis that athletes of various sports may experience specific features of self-reliance. It has been established that self-reliance level is higher than average for representatives of combat and complex-coordinated sports. Representatives of cyclical and speed-strength sports are characterized with an average self-reliance level. Combat and complex-coordination sports are very similar according to the specifics of self-reliance expression. Self-reliance possibility data comparison among cyclical and speed-strength athletes showed their certain homogeneity. It has been revealed that only a future activities reflection is closely related to a self-reliance among boxers (Spearman rank correlation = -.478). There are two correlations in the sample of gymnastics representatives. An increase in the overall reflection index (Spearman rank correlation = -.489) and the future activities reflection index (Spearman rank correlation = -.427) leads to self-reliance decrease among gymnasts. The inhibitory effect of future activity reflection on the athletes’ self-reliance level has been established empirically. We determined that self-assessment is a personal formation that actualizes self-reliance of swimmers and discus throwers. (Spearman rank correlation = .618). Conclusions. The handled comparative analysis of self-reliance of different sports athletes has verified its high informative value. Statistically significant differences recorded in the self-reliance level among of boxing, gymnastics, discus throwing and swimming athletes. The high informative value of used questionnaire allows recommending it as a screening tool during promising athletes selection.

Background and Study Aim. Stability of performances at competitions with a preset effectiveness in the presence of sports competition is the result of the reliable functioning of the psyche of an athlete. The hypothesis of the study - mental reliability is associated with certain individual psychological properties, the similarity and difference of which is determined by the level of success of an athlete. The purpose of the study is to identify a set of personality determinants that affect the mental reliability of an athlete. Material and methods. The study involved 58 fencers aged 17-18 years (M = 17.47 SD = 0.53). In this paper, the measurement of the mental reliability of an athlete was carried out using an integral assessment of the success of sports activities developed by E.V. Melnik and E.V. Silich. According to the final success rate, the total sample of the subjects was divided into 2 groups: «successful» and «unsuccessful». For the study of the leading individual psychological properties of the personality, 16-PF multifactor personality questionnaire by R.Kettel was used in the work. The data processing package SPSS was used for data processing. Results. Significant differences were established between the groups of «successful» and «unsuccessful» athletes in the majority of individual psychological properties. The importance of focused analysis and the development of individual mental properties as internal prerequisites for the mental reliability of fencers has been acknowledged. The relationship of personal factors with the success in sports activities is presented. A high level of correlation between the integral indicator of the success of competitive activity and intelligence (factor B), emotional stability (factor C), emotional hardness (I), confidence (O), independence and autonomy (Q2) is revealed. A significant correlation was found between the average level of success in sports and caution (F). This confirms the possibility of applying the methods of research of individual psychological properties of a person when studying the causes of lesions and the prerequisites for the erroneous actions of an athlete. Conclusions . The success of sports activities of fencers does not depend on one individual psychological property of a person. This is the result of a combination of most of them. A greater number of reliable relationships have been revealed between the final indicator of the fencers’ success in sports activities and personal factors from the emotional properties group as compared to communicative and intellectual properties groups.

The study purpose is to establish differences in the joint activities of soccer teams of different age. Materials and methods. Psychological methods for indicators of joint activity of sports teams were used. Statistical analysis was performed using non-parametric analysis of variance (Kruskal-Wallis H-test). The study involved 105 soccer players, including 37 boys aged 15–18, 45 juniors aged 19–21 and 23 adult athletes aged 22 and over. Results. In the young soccer players, group interaction, intellectual communication, psychological compatibility, as well as indicators of real and reflective group subjectivity are higher than in the adult and junior teams. The levels of group organization, diligence and success in performing sports tasks are dominant in the adult teams. At the same time, the integrative characteristic of joint sports activities is group efficiency, which is presumably the most pronounced in adults, thus characterizing the processes within the mental organization of joint activities of soccer players. It is the result of their cooperation, a transformed form of external teamwork. Conclusions. The organization of joint mental activity differs in different age groups. This affects the formation and development of intra-group position of the athletes, influencing their optimal involvement in the team in the performance of designed or creative functions. Keywords: soccer players, efficiency, interaction, subjectivity, organization.
