 AbstractWith the help of the 94Fifty technology we were able to analyze the three-point shot. We were curious to know whether the majority of the shots are recommended by the manufacturer of the measuring system and carried out in preplanned intervals of entry angles, the rotation of the ball, and the release time of the ball, and we wished to find out the consistency of the aforementioned parameters between the guards and other players. The hypotheses were tested on a sample of 52 great male basketball players, aged 18 and 19. We deducted that most of the shots from the distance of 6.75 m occur under a entry angle greater than 42°, but not in the estimated interval (between 42° and 48°); that most of the shots do not occur in the estimated interval of the rotation of the ball (from 130 to 150 revolutions/minute); and that most of the shots do not occur in the estimated interval of the release time (< 0.7 seconds). When it comes to the consistency of the before mentioned parameters we did not find any discrepancies between the guards and other players. Based on the results a question arises: did the manufacturer of the measuring system adequately form the intervals of the aforementioned parameters or does the problem lie in the performance of the shots by the chosen players? | ||

| Abstract The goal of this transverse research was to establish the correlations between morphological characteristics, and identifying the latent morphological structure. In the morphological space, a group of 12 standard anthropometric variables was measured. The sample encompassed 158 female subjects, aged 12 to 14 years, from volleyball clubs of the Kolubara-Macva Inter regional Serbian league. Statistical data analysis was conducted using Pearson's coefficient of correlation and Principal component analysis (PCA). Results from the correlation analysis showed statistically significant linear correlations in almost all anthropometric variables of female U14 volleyball players. Using the method of Principal Component Analysis (PCA), together with the Kaiser-Guttman criteria and Varimax rotation, a three-component model was extracted which comprised 83,35% of proportion of the total variance of manifested anthropometric variables. This model was structured by the hypothetical factors with their characteristic roots (ƛ > 1), which were interpreted as: longitudinal skeleton dimensionality (F1), body volume and body mass (F2), and subcutaneous fat tissue (F3). The limitations of this study were discussed, as well as recommendations for future longitudinal research. Objectively, an insufficient amount of conducted empiric studies so far presents a motive for other authors to establish a relationship between morphological landmarks and defining the build of the morphological space in preadolescent population of female volleyball population. | ||

| Abstract The aim of this paper was examine whether a physical education class can result in a level of dehydration which, according to a large number of authors, causes a drop in cognitive and working abilities. In the light of present knowledge, changes are notable even when the level of dehydration is 1–2% of the body mass loss. Besides, it was necessary to determine whether the respondents had problems caused by dehydration and their beverage consumption habits. The research included 28 eight-graders of a primary school in Belgrade, aged 14 to 15. The analyses of body structure, body mass and water content was done by the analyser "InBody 370", followed by a physical education class when the station work was used as the organizational and methodical form. After the class, students' body mass was measured. The difference in body mass before and after the class represented the lost body fluid and was used to establish the percentage of dehydration. Т-test for dependent samples showed a highly significant difference (p=0.000) in body mass before and after the class. In 86% of students, the percentage of dehydration was more than 1% of BM (the average value of 1.20%±0.22%). These results indicate that a physical education class can cause, in most of our students, the level of dehydration which, according to a large number of authors, can bring about the drop in various (mostly cognitive) abilities, which can lead to confusion during other classes after the physical education class. Results of the questionnaire showed that most of students (68%) had a fluid intake only when they feel thirsty, while 25% does not have any fluid intake during physical activity. The largest number of students (43%) feels the lack of concentration, fatigue, drowsiness and lethargy during classes following the physical education class. Sometimes this condition appears in 39% of students while only 18% of them do not feel any changes. Evidently, there is a problem of insufficient hydration in students. This problem should be solved in an organized way, at the school level. Students should gain knowledge about proper hydration. Another important factor is making water and other useful drinks available to students. The young should be encouraged to drink water more often during school and especially after the physical education class. | ||

| Abstract The problem of the use of banned substances (doping) in sport has been, is and will be an ongoing problem that undermines the very spirit of sport, beauty and pleasure, and very often the health of athletes. Therefore, it is essential to solve this problem, if possible, permanently, although it is sometimes simply impossible to do. It is this research that is designed to gain a real insight, express attitudes and perceptions of students on the use of doping in sport that is the information on this sports phenomenon of the modern age. The study included a total of 141 high school students (Gymnasium and Touristic technicians) from Pale, male, aged 15-19 ± 0.5 years. The main objective of the study was to test the level of knowledge and identify students' attitudes about the use of prohibited substances in sport. To collect the necessary information has been used an anonymous questionnaire with 13 clearly defined questions (11 closed questions and two open-ended questions) that are related to specific knowledge, attitudes about doping in sport. The obtained results are relevant to the global indicator of awareness, knowledge and attitudes of the population of high school students about the problem of today's modern sport which is called doping. As many as 75% of the students the athletics, cycling and sports games marked as sports that are most marked by doping scandals, and 56% were tennis, golf games stated as a sport with the least number of doping scandals. | ||

| Abstract This work shows the results of research whose goal was to consider particulars on the start and chronology of gymnastics and combat civil association foundation in the Kingdom of Serbia in a critical manner. That was possible thanks to the fact that one unpublished document in the legacy of Jovan Vanja Petrovic was found in the Museum of Physical Culture within Faculty of Sports and Physical Education in Belgrade. The contents of a few found letters created one new perspective on the former knowledge about the first attempts of sports initiation in Serbia, outside Belgrade. | ||

| Abstract Sport is defined as an activity that involves competition, specific preparation for the competition, specific relationships and connections in that area of activity taken as a whole. Analysis of competitive activity is the basis for a rational approach to the planning, programming, implementation and evaluation of the effects of systematic training process. Subject to this study was to analyze competitive activities of volleyball players in the play-off stage of "Wiener Städtische" Serbian league in season 2012/2013. The aim of the research is to determine characteristics of the volleyball game structure in competitive activity, to determine the technical-tactical elements with a statistically significant contribution to the achievement of positive results in the competition and to perform certain conclusions, with the help of research results, regarding the design of the training process. Description of elements was performed in the research, the contents that describe competitive activity in men's volleyball were explored, and then comparative analysis of these elements was performed for different levels of team performance. We can conclude that, based on these results, there is a statistically significant difference between successful and less successful men volleyball teams in only three variables, namely: the efficiency coefficient of serve, efficiency coefficient of block, efficiency coefficient of attack. This data is absolutely correspond to considerations in practice, which is that these three elements directly bring a point in the field, and therefore by observing them we can determine the winner of the match, with the highest certainty. Other elements, though necessary may influence the final outcome in men's volleyball to a lesser extent. Data from this study should be used primarily for modeling volleyball players training, with the ultimate projection on training improvement and game efficiency increase. | ||

| Abstract Extracurricular activities offer students the opportunity to learn and train sports not provided by curriculum of physical education. Staying active in nature in terms of the orientation movement is greatly beneficial for the development of mental and physical abilities. The aim of this paper is to present opportunities for the organizing orienteering section in elementary school. Descriptive method was applied to be shown plan and program of the section designed so that teachers of physical education in their schools provide implementation of orienteering section for 30 classes. The expected outcome of orienteering section is to enable students to independently perform at competitions. Training is done through the implementation of goals and objectives of sections, using methodological procedures with respect to the pupils' age, prior knowledge and the pace of overcoming the training. Plan and program section includes mastering the basic technique in orienteering, through theoretical and practical work. In working with students who are for the first time in orienteering, the main focus should be on reading the maps, and understanding the relationship between nature and maps. In primary schools there are possibilities to organize orienteering section, and there is a significant correlation with other subjects. The presented model provides the optimal level of theoretical and practical knowledge that students can apply in school competitions. | ||
