The aim of this research was to examine differences in the use of self-handicapping strategies in athletes and non-athletes, changes in self-handicapping strategies that can occur with the approach of an important event, and the relationships between these strategies and personality traits, gender, and some external criteria such as performance. The sample included 183 subjects (mean age 21.16 years) consisting of 102 non-athletes and 81 athletes. Three questionnaires were used: VP+2, for measuring personality dimensions of seven-factor model, SH-17, for the assessment of changes in the use of self-handicapping strategies through time and a general biographical questionnaire. A general linear model for repeated measures was used for data analysis. Significant correlation was found between self-handicapping strategies and the number of medals and awards won at international and domestic competitions. The results also showed a positive correlation between self-handicapping strategies and dimensions of Neuroticism and Extraversion and negative with Conscientiousness. Also, a statistically significant difference in the use of self-handicapping strategies was found between athletes and non-athletes, showing that non-athletes express more self-handicapping behaviour. The results indicate that the frequency of selfhandicapping behaviour does not change through time. The effect of gender on self-handicapping is not significant, but there was a statistically significant interaction effect of gender and population on self-handicapping behaviour. It indicates that male non-athletes are more prone to self-handicapping 10 days before an important competition (exam or public speaking for general population, or “game of the season” for sporting population) compared to male athletes. These results, apart from the gender differences, are consistent with the results of previous studies. Limitations of this research and possible directions for future studies were also considered. 

Studies concerning the effects of different invasion games on physical fitness in school children are scarce. Consequently, the purpose of this study was to examine the effects of the application of invasion games on physical fitness in primary school children. A total of 62 primary school children aged 10-12 years voluntarily participated in this study. They were divided into experimental (32) and control (30) group. Physical fitness of children was estimated by the following tests: Standing broad jump, Vertical jump, Bent-arm hang, Sit-ups, Push- ups, Medicine ball test and Andersen test. The experimental group had twice per week invasion games on non-consecutive days for 12 weeks. Participants in control group did not perform specific program but attended their regular PE class twice per week. Compared with initial measurement, there was a significant (p < 0.05) improvement in vertical jump test for both groups. Furthermore, the group that participated in the invasion games program made significantly greater gains compared to the control group (p < 0.05) in Standing broad jump (8.2%; ES=0.56 vs. 3%; ES=0.2) and Medicine ball test (8.2%; ES=0.6 vs. 3%; ES=0.3). There was a significant improvement in bent arm hang, sit ups and push-ups in experimental group. Compared with initial measurement, there was a significant (p < 0.05) improvement in Andersen test in invasion games group, which was not the case with control group (p>0.05). To conclude, invasion games were an effective way of improving physical fitness in primary school children, because the results of this study indicate that this method was more effective for physical fitness than traditional school program. 

Measuring of morphological characteristics and motor abilities was performed on the sample of 51 male students of the secondary traffic school “Pinki” from Novi Sad.  Body height and body mass were used for measuring of morphological characteristics, and results of standing long jump and running at 30 meters with standing start were used for measuring of motor abilities. The body mass index was calculated after the results were obtained. The aims of the study were to establish and analyze differences in the results of morphological status and explosive strength of students measured in different periods, in the first measurement when the subjects were 15 years old and in the second measurement when the subjects were 17 years old. The data obtained in the study were analyzed using repeated measures ANOVA. The obtained results indicate the existence of statistically significant differences between first and second measurement in all morphological characteristics and motor abilities, at the level of significance of p<0.05.A significant increase in morphological characteristics and motor abilities with age, indicating that boys have adequate growth and development for their age.The age factor has a significantly stronger influence than the factor of the curriculum for the physical education in this high school. 

Fencing is very dynamic and combative sport, with the following requirements of competitors: instant resourcefulness, precision, courage and fast reaction in different situations. It is just for this reason that the training of young fencers involves improvement of all motor abilities focusing on agility, speed, and explosive strength. The aim of this research is to determine gender-related differences of motor abilities in children engaged in fencing. The sample consists of 50 children (26 boys and 24 girls) whose average age is 10.46 years and, who train fencing in the “Omladinac” in Zrenjanin and “Vojvodina” in Novi Sad. Motor abilities are tested by means of four motor tests. Differences are determined using multivariate analysis of variance and univariate analysis of variance. The findings indicate that there is statistically significant difference related to Deep forward bend on the bench and T-test, which is in favor of girls, Long jump test from the standing start in favor of boys, whereas Tapping test does not show any significant difference between boys and girls. Numerous research works show that early maturing girls have better results of motor performance than those with a slower process of maturation (11-13 years), whereas individual differences in terms of motor performance depend on growth and development, especially in boys. Matching of results is related to the observed statistically significant differences in explosive strength in favor of boys and suppleness in favor of girls. 

The objective of this study represents the sports branding, while the main goal will be directional to explaining the contemporary sports product and making a brand. The main tasks of this study are, the first discussing the sports branding nowadays and newly created sports products as well as drawing attention to the specific nature of the branding of sports products as a separate field of branding in general. During making of this study, the authors used descriptive method with consulting of competent literature. The previous authors’ experience in this field was also so useful. Moreover, the author used the analytic method and parallel method that is the most productive if you make some inferences about some appearance. From the reason sport branding did not develop separately, it is the fact that it represents an integral part of the overall branding procedure; however, sport branding has some specialty in relation to other areas, mostly due to the reason, sport industry has much more unpredictable nature than most of other industries. This study made general retrospection of common characteristics and differences among sports branding and branding in general that might be relevant for many researchers in this area. Sports branding is developing rapidly around the world, the dominant example of this development is most evident in the “sports industry” in the United States. However, the sport branding is not at the expectable level in Montenegro, and working on recognizing Montenegrin contemporary sports product and making a brand must be more prominent nowadays.
