(1) Background: Psychological parameters are relevant in the practice of judo. Previous studies have shown that parameters such as anxiety or motivation can have a negative or positive impact on the athlete’s performance and general well-being, depending on the athlete’s perception. This systematic review aimed to summarize the studies examining the influence of various psychological parameters on well-being and performance in judo athletes; (2) Methods: We followed preferred reporting elements for systematic reviews and meta-analyses. We searched the Web of Science database for studies that explained the role of these parameters in elite athletes. Of the 286 articles initially identified, 17 met our eligibility criteria and were included in the review. In total, we analyzed data from 721 judo athletes; (3) Results: The studies found have demonstrated the impact of various psychological parameters during high-level performance and how these parameters can influence and lead an athlete to win or lose a competition. The feelings of tension, anger, anxiety, and nervousness were significantly increased in athletes who were facing defeat, while a decrease in the same segments and an increase in motivation among athletes who were experiencing better performance was observed. Further research under standardized conditions is needed to better understand the effects of these parameters on judo athletes; (4) Conclusions: Considering the athlete’s psychological state can affect performance, and it is therefore important to monitor and train these factors.

Physical education is considered to be a favorable context for accomplishment of important educational outcomes and promotion of physical activity in children and youth. The real scope of physical education instruction largely depends on student motivation. Self-determination theory, as a specific macrotheory of motivation, offers a rewarding framework for understanding student motivation in physical education instruction. The paper presents the basic tenets of self-determination theory, the most important studies in the domain of physical education and didactic and methodical implications. Two mini-theories within the self-determination theory are analyzed in more detail, the cognitive evaluation theory and the organismic integration theory. Empirical verification of the theoretical tenets indicates the existence of typical motivational profiles of students in physical education instruction, the basic psychological needs as mediators of influence of social and interpersonal factors on student motivation, followed by the importance of motivational climate, students' goal orientations and teaching style for self-determination of students' behavior in physical education instruction. Didactic and methodical implications refer to the need for developing a more flexible curriculum of physical education, encouraging a motivational climate, task-focused goal orientations, and, especially, encouraging the perceived moving competence of the student.

Considering that self-perception of competence in the relevant domains is important for understanding of individual?s behavior and achievement, the study analyzed the effects of age and gender on global self-worth and domain-specific selfperceptions. The cross-sectional study included 1130 participants of age range 8-23 (520 males and 610 females). The participants were tested by the equivalent forms of six subscales from ?Self-Perception Profile for Children?, ?Self-Perception Profile for Adolescents? and ?Self-Perception Profile for College Students?. Subscales measured self-evaluations across domains of scholastic competence, social acceptance, athletic competence, physical appearance, behavioral conduct and global self-worth. Two separate MANOVAs revealed a significant main effect for age in male subsample (Wilks? Lambda =.83, F (12, 1024)=8.35, p<.01) and in female subsample (Wilks? Lambda =.80, F (12, 1204)=11.80, p< .01). An analysis of variance showed that the effect of age in males was significant in physical appearance, behavioral conduct and global self-worth, while in females significant differences were registered in scholastic competence, athletic competence, physical appearance and behavioral conduct. Pedagogical implications refer to enhancing self-concept in youth by appropriate teaching strategies and supportive learning environment. Learning experiences within physical education might be particularly beneficial for female adolescents.

Principal measuring characteristics and norms of Raven?s colored matrices were determined on the sample of 2.334 children from Vojvodina at the age of 3.5 and 11. The basic metric characteristics were determined according to classical test theory (CTT) and item response theory (IRT). By testing a dimensionality it was showed that the test had one main object of measuring. The norms were also evaluated in terms of their precision in statistical and psychometric sense. It was found that there was no statistically significant difference in solving the test requirements between boys and girls at any age, nor was there any significant interaction of gender and age. Reliability of the test at the age group of 6 - 11 was over 0.85, at the age of 5 it was 0.75, whereas at the youngest age it was only 0.59. The complete test was too easy at older ages due to the Flynn?s effect. It is owing to this reason that a conclusion can be drawn that there?s a big question mark over its application at the age of 11,and even 10. It is recommended that standard Raven?s matrices should be used at that age. .

Introduction. Psychomotor re-education represents a multidimensional therapeutic approach in dealing with children and adults with psychomotor disorders. Therapeutic programs should be based on individual differences, abilities and capabilities, relationships, feelings and individual developmental needs as well as emotional condition of a child. Body and movement as the bases of the treatment. A movement, glance, touch, voice and word, all being an integral part of a process of psychomotor re-education, are used with a purpose of helping children to discover their own body, their feelings, needs, behaviour. When moving, children discover the space of their own bodily nature, and, subsequently, gestural space and objective space. The body represents a source of pleasure and the freedom of movement, as well as one?s own existence, are soon to be discovered. Practical application. An adequate assessment is a precondition to design a work plan, select the best exercises for each child individually and direct the course of therapy. This is the most suitable method for treating children with slow or disharmonious development, mentally challenged children, children with speech and behaviour disorders. It is also used in the treatment of children with dyspraxic difficulties, difficulties in practognostic and gnostic development, pervasive developmental disorder and children with lateral dominance problems. Conclusion. Therefore, a systematic observation seems to be necessary as well as an increased number of research projects aimed at assessing results obtained by exercises in order to get a more precise insight into the process of re-education, selection of exercises, duration period and possible outcomes.

The aim of this paper is to examine the differences in particular dimensions of selfconcept in female and male adolescents depending on sports engagement, as well as to determine which domain-specific self-perceptions provide the highest contributions to global self-worth in female and male adolescents engaged in sport and those not engaged in it. This research included 400 subjects at early adolescent age, of both genders (235 females and 164 males) further divided to sub-samples of athletes and non-athletes. An adapted version of a scale Self-Perception Profile for Adolescents (Harter, 1988) was applied, which consists of nine subscales. The obtained results indicate that sport-engaged adolescents of both genders provide more favourable perception of themselves in most tested aspects of self-concept than those not engaged in an organized sports activity. Engagement in sport has special effect on selfconcept of male adolescents. Results of multiple regression analysis point out unambiguously the significance of self-perception of physical appearance in global self-worth of adolescents of both genders, irrespective of whether they are involved in sports activity or not.
