Introduction. Handball and volleyball are among the world's popular sports, which are played practically in every country at different levels of competition. The aim of this study was to determine the differences in somatotype and morphological characteristics between young handball players and volleyball players as well as the differences in the results of functional body mobility tests between the tested groups. Material and Methods. The research included a sample of 23 female athletes who were divided into two subsamples, as follows. A total of 12 athletes were from the Handball team and a total of 11 athletes were from the Volleyball team.  The following anthropometric measurements were conducted: Height and body mass, four skinfolds (triceps, subscapular, supraspinal and calf), breadths (humerus and femur diameters) and girths (arm and calf). Body mass (kg) and body fat (%) of the subjects were measured by the method of bioelectrical impedance (TANITA 545N) with an accuracy of 0.1 kg. Functional Movement Score is a scanning system which includes seven steps (i.e., deep squat, hurdle step, in-line lunge, shoulder mobility, active leg raise, trunk stability push-up, and rotary stability). Results. The results of the study in female handball players recorded a higher percentage of body fat and body mass index compared to female volleyball players (p <.05), while no statistically significant difference was recorded in body weight and height. Analyzing the somatotype of players, it is noticeable that handball players have higher values of endomorphism and mesomorphism, while volleyball players have higher values of ectomorphism. Statistically significant differences were observed in mesomorph and ectomorph (p <.001). In the Functional Movement Screen test, it was noticeable that statistically significant differences were recorded in the two variables (Shoulder mobility and trunk stability push up) in favor of the volleyball players, as well as in the overall standings, while in the other variables no statistically significant difference was recorded. Conclusions. Determining somatotype must occupy the attention of coaches who work with young athletes. Movement-based assessment serves to pinpoint functional deficits (or bio-markers) related to proprioceptive, mobility and stability weaknesses.

This study aims to determine the effects of a program based on a progressive increase in the number of nage-komi repetitions (throws) on a specific judo fitness test (SJFT). The research was conducted on a total of 20 respondents. In SJFT for research purposes, 12 variables. Descriptive statistics and paired t-tests for dependent samples of initial and final testing were used for data processing. The results of the study showed significant statistical deviations in the number of throws in the first 15 seconds, with the pulse measured immediately after testing and the SJFT index (p <005). There is a noticeable need for a table to classify SJFT results for young judoists. Based on the obtained results, we can conclude that the programmed activity had positive effects on the results of the SJFT, ie that the index was statistically significantly lower in the final than in the initial testing. Taking into account the results obtained, calculated by the SPSS 22 t-test for dependent variables, the values ??of the young judoist index and the values ??of the senior index show noticeable differences. While their results can be classified into appropriate categories, the results of young judoists can be classifieclassifiedrity, under, ad and the rest as very bad. Some results could not even be ranked, so we conclude that it is necessary to make tables for classifying the results of young judoists. The obtained results can be used as guidelines for more efficient programming of the training process. Keywords: cadets, judo, juniors, SJFT test, training.

Background and Study Aim. The nutritional status of children can be assessed on the basis of clinical examination, laboratory procedures and anthropometric measurements. Height and body weight are most often used to determine nutrition. Children and adolescents who are at risk of being overweight often also become obese adults. Material and Methods. The research was conducted on a sample of 136 students (67 boys and 69 girls), with an average age of 11.56 years. The aim of the study was to determine the degree and differences in the degree of nutrition and body composition in boys and girls of pubertal age. Results. Based on the obtained results, T-test for small independent samples, it was determined that there are no statistically significant differences between boys and girls, both in the degree of nutrition and body composition, estimated by 10 variables using bioelectric impedance InBody 720. Also, it was found that 19.70% of boys are obese, as well as 17.40% of girls. Cumulatively with the percentage of malnourished respondents, a total of 61.50% of boys were not normally fed, as were 37.70% of girls. The obtained results indicate the need for a more extensive review of the analysed segments and a significantly larger sample of respondents, in order to act preventively in the fight against obesity, as the leading epidemiological health problem of today. Conclusion. It is obvious that physical activity based on physical education classes is not sufficient or is not sufficiently represented to meet the challenges of the modern way of life of children.

The morphological characteristics of elite basketball players are of great interest to some authors in order to define the best morphological profile for a particular playing position and different levels of competition. The aim of the research was to determine the differences in morphological characteristics in professional basketball players in relation to the playing position in different league competitions and to determine the relevance of these characteristics for success in the game. The survey included a sample of 773 elite basketball players competing in five different leagues in Europe. In our study, we found that centers are significantly taller and heavier than guards and forwards are. In addition to other components of basketball (technique, tactics, coach strategy), body height, body mass and body mass index play a major role in overall performance in a basketball game in all positions. The obtained data can help coaches in the scouting process in which leagues in Europe are played by players with certain morphological characteristics in relation to the playing position.

There is a view that playing sports is positively related to pupils' academic achievement. Results of studies worldwide indicate this correlation, while few studies have been done in Bosnia and Herzegovina on this problem. The current study aims to expand on findings from previous studies by examining associations between (1) mode: active vs. recreational); (2) type: individual vs. team based and (3) a particular kind of sports and academic achievement particularly math achievement among middle school children. Population involves middle school pupils in two urban areas in Bosnia and Herzegovina and research sample consists of 1036 female and 1055 male pupils wanting to take part in study voluntarily. Kruskal-Wallis and Wilcoxon test were conduced to obtain results. Results show that middle school pupils who are actively involved in sports have better overall midterm academic success as well as better mathematics achievement compared to those who are involved in sports recreationally or not at all (p < 0.001). On the other hand, differences do not occur between pupils who are engaged in team or individual sports. Also, pupils who practice football were found to have lower school performance compared to pupils who practice some of the other sports.

Proper body posture should be at the very top, as this is the basic prerequisite of good health, normal growth, and development. The aim of this research was to determine significant differences between the initial and final measurements in the results of body deformities in students of classroom teaching. The study was conducted on a sample of 1105 students, aged 5 – 12 years. Diagnosis of body posture was performed according to Napoleon Wolanski's criteria. Measuring instruments/tests were used to measure the curvature of the spine, and the check of the structure of the feet was performed by the method of plantography. By analyzing the posture variables of individual body parts of the sample studied, using descriptive statistics, it was determined that there was a statistically significant representation of physical deformities, as well as statistically significant differences between the initial and final measurements in the results of physical deformities of class teaching students. The analysis of the obtained results provided data showing that in the initial measurement 231 students of class teaching have chest deformities, 792 students have spinal deformities, 267 students have leg deformities and 671 students have foot deformities. In the final measurement, 123 class teaching students have chest deformities, 488 students have spinal deformities, 133 students have leg deformities and 439 students have foot deformities. Based on the research it can be concluded that the frequency of physical deformities can be significantly reduced by planned and continuous corrective procedures, i.e. by applying appropriate content in physical and health education classes.

This paper aims to analyze the statistical parameters and to determine the differences between the water polo tournament in Sisak and the water polo tournament in Sarajevo. Situational efficiency utilizing certain variables shows us the most important parts of the game during a water polo match. Statistics is a scientific discipline that studies the methods of collecting, collating, analyzing, and interpreting data. The sample consists of 336 water polo players, from six clubs of two age categories from the league of Canton Sarajevo and six clubs of two age categories from the Sisak International Tournament, in the "junior and cadet" categories for men born in 2003 and 2004, 2005. The sample of variables consists of 9 tests to assess situational efficiency in a water polo game that defines the main characteristics of a water polo match. The following will explain the observed variables: goals scored, attempt to score, goal from action, center to score, anchor to score, penalty, attempt from penalty defended by the goalkeeper or player missed, foul on the counter-attack, sprint - counter with a goal scored. The results of the H square test show that there are statistically significant differences (p .000) in the analyzed segments of the water polo match. It can be concluded that the teams in the tournament in Sisak are better organized because in every aspect they have achieved better results in comparison to the Sarajevo tournament. The teams from Sisak were better and faster swimming because a lot of goals were scored by counter-attack, more attempts to shoot at goal (Sisak), fewer penalties, which means that in Sarajevo is rough play and greater success of winning teams in penalties.
