Man consists of different abilities and traits. The degree of development and the level of achievement, as well as their mutual relationship, are different from person to person. Morphological characteristics are the characteristics responsible for the dynamics of growth and development, as well as for the characteristics of the body structure. Motor abilities are features that participate in solving motor tasks and that can be developed to a greater extent. We will find out the difference in these abilities between students active in football and physically inactive students through the results of this master's thesis. The goal of the research is to determine the differences between students who are actively engaged in football and those students who are not active in sports. The research was conducted on 52 subjects, students of an elementary school. Keywords: Motor abilities, elementary school, students

The aim of this research is to identify the motivational structure of recreational exercisers and to investigate differences in motivation with respect to gender, ie to determine the hierarchy of motives for which they choose recreational exercise. This research shows that the strongest motivation for recreational exercise is maintaining and improving health, and certainly relaxation. After them, the most important motivation is socializing and meeting new people, and improving and maintaining physical ability. The research also showed that there are very small differences in the motives for exercise in relation to the age of the respondents, and they are reflected in good looks and fun, while relaxation and relaxation and improvement and maintenance of physical ability are equally important for all ages.

This research is aimed to determine the differences in the racing performances of elite European and Latin American footballers. The research was conducted on a sample of N = 157 top football players, aged 19 to 35, who played all 90 minutes in the first round of the group stage of the competition at the 2018 World Cup. Respondents were classified into two groups, where group I (N = 103) consisted of football teams from Europe, and group II (N = 54), consisted of teams from Latin America. The obtained data showed that 8 out of 13 variables have the characteristic of heterogeneity with a higher value of variance than the arithmetic mean. The results of the T-test showed that only 4 of 13 variables had statistically significant differences. Footballers from European national teams are on average taller than Latin American footballers by just over 3 cm. European footballers had a 4% greater (p> 0.05) total distance traveled, distance in the first and second half of the game than Latin American footballers.

This research aimed to determine the differences between the junior (U18) water polo players of five Croatian and one Montenegrin clubs in the anthropometric characteristics and body composition. The first sample of the subjects consisted of 14 players of the water polo club Mladost average age 17.57 ±0 65, the second sample consisted of 11 players of the water polo club Sibenik (17.82±0.65), the third sample consisted of 13 players of the water polo club Primorje (17.23 ±1.01), the fourth sample consisted of 15 players of the water polo club Mornar (17.13 ±0.64), the fifth sample consisted of 13 players of the water polo club Medvescak (17.92 ±0. 6) and the sixth sample consisted of 10 players of the water polo club Jadran Herceg Novi (Montenegro) (17.70 ±1.34). In the 2010–11 season, these clubs participated in Regional Water Polo League, commonly known as the Regional League or Adriatic League in Sou theast Europe. The measurements was conducted in the competition season in the period September-December 2010, at sports centers and swimming pools of water polo clubs that participated in the research. Anthropometric characteristics and body composition were evaluat d using a battery of 12 variables: body height, body weight, arm length, arm span, leg length, foot length, chest skinfold, trice ps skinfold, back skinfold, abdominal skinfold, upper leg skinfold and body mass index. The standard central and dispersion parameters of al l variables were calculated. The significance of the differences between the water polo players of six teams in the variables for ssessing anthropometric characteristics and body composition were determined using ANOVA and an LSD Post Hoc test.Based on the central a nd dispersion parameters, it can be stated that the values of all the variables are highly similar to all of the water polo player s of these six clubs. The ANOVA test found that the water polo players of the six international clubs do not have statistically significant di fferences in the variables for assessing anthropometric characteristics and body composition.

On the sample of 10 selected swimmers, national junior champions and national junior record holders of B&H, was applied a system of 26 morphological variables. The main issue was to determine quantitative degree of correlation of hypothesis factors which are responsible for correlations between manifest variables in this research. The number of morphological variables was reduced with relatively less number of independent latent variables. Those latent morphological variables can explain mutual relations of analysed set of manifest variables in tested swimmers. Three independent morphological factors were determined: longitudinal dimension factor, factor of free fat and transversal dimension factor. Those factors were in the certain degree related. Orthoblique factors were reviled relation between longitudinal dimension and transversal dimension with high correlation 0.7609, while factor of free fat was separate factor. The most marked morphological separate variables were variables of transversal dimensionality: wrist diameter (ADRZ), knee diameter, ankle diameter, hand bandwidth (ASSA), foot bandwith (ASST), biacromial bandwith (ABIK). It is obvious that specially formed structures of morphological dimensions of elite level swimmers are result of genetic predisposition, selection and training process in swimming.

On the sample of 10 selected swimmers, members of national swimming team of Bosnia and Herzegovina, it was conducted the research with the aim of finding those anthropological characteristics that are responsible for success in swimming. The paper presented the results of analysis of the influence of some anthropological components, which directly influences the result of swimming. It is tested the hypothesis that the significant correlation between anthropological dimension set in latent form and the results of success in swimming is expected. Conducted a regression analysis, but in a way that the previously isolated factors as the latent dimension, brought in connection with a sports result in swimming. This was due to determine the maximum possible model from existing data. Sixteen of the latent dimensions or factors are included, of which: 3 morphological factors, 5 isokinetics factors, 2 functional factors, 2 factors analysing blood composition and 4 motor factors. All these factors together represent a set of anthropological characteristics of swimmers in a way that they are connected and integrated into the whole. Results of this study show that success in swimming can be considered functional abilities, especially the maximum consumption of oxygen – VO2max, and balanced systolic and diastolic pressure. Then, the optimal morphological structure, which seeks specific swimming model, and also highly developed but at the same time and very specific colored motor abilities model differentiated in a way that ensures optimal operation in extremely specific medium, such as water. Finally, indicators of blood and isokinetic indicators can be considered much less important for achieving results, but it is not excluded that they may be important in the training process of transformation in individual stages.

On the sample of 10 selected swimmers, members of national swimming team of Bosnia and Herzegovina was applied a system of 27 variables. 26 predictive variables of motor space and one criteria variable of result achievement were applied to determine relations between some morphological characteristics and result achievement in swimming. Leading task was to facilitate a system from predicative selection of young swimmers. While determining statistically significant relations between the criteria variable and the system of predicative variables, the SRA regression analysis led to significant prediction of the criteria. In this research the regression of the sport result in swimming undoubtedly indicate the importance of motor space. Multiple correlations were severe (0.90), and the interpretation of the criteria with 81 % was also considerably large. This means that it is possible that morphological variables make prediction of results in swimming, and that morphological constitution has direct repercussions on the swimming result. Based on the analysis of spent can be concluded that swimmers must not have any extreme morphological events, but balanced, comprehensive and homogenous composition with a somewhat less importance fat.

The parameters of situational efficiency in basketball are interrelated and represent the interaction of technical, tactical, fitness and all other factors relevant to success. By registering and analyzing the parameters of basketball players' situational efficiency, it is possible to arrive at precise values of playing and team efficiency, which provide guidelines for more successful planning and programming of training technology. The aim of the study is to identify differences in situational efficiency parameters between the first and second regional ABA Basketball Basis, based on statistics made up of the individual performance of each basketball player within the team. The study was conducted on a sample of 24 clubs from two ABA leagues, in the regular competition for the 2018/19 season. Variables make the frequencies of successfully and unsuccessfully executed elements of technical and tactical action during the match in the stages of attack and defense. The data was downloaded from the official website swww.aba-liga.com and www.druga.aba-liga.com. Nine variables were taken to assess situational efficiency: 1. Average of balls inserted by 2 points (SHUT2P%); 2. Average of balls scored by 3 points (shot 3 P%); 3. Average free throws completed (FT%); 4. Defense Leap (SDEF); 5. Attack Jump (SOFF); 6. Assists (ASS); 7. Obtained balls (STE); 8. Lost Balls (TOURN); 9. Personal fouls (FOUL). Descriptive statistics were used for statistical data processing in order to better describe and understand the data set. The T-test for independent samples established statistical significance in the difference of situational efficiency parameters between the two regional leagues. There is a significant difference in the parameters of situational efficiency between the clubs performing in ABA1 and ABA2 regional league with two parameters, the average of balls inserted by 2 points (sig., 011) at the level of 95% significance, where the clubs from ABA2 regional had a better percentage. Basketball leagues and average personal fouls (sig..000), where, on average, more offenses were made in the ABA1 regional basketball league. Basketball players in two-regional ABA leagues differ statistically and significantly in 2 parameters of situational efficiency, shot by 2 points and personal mistakes. With all other parameters results exceeded the significance value of 95% (p <0.050).
