The research was conducted on a sample of 102 respondents (teachers) employed in primary schools in the Zenica-Doboj Canton of the Federation of Bosnia and Herzegovina. The main objective of the research is to determine the attitudes and opinions and possible differences of the respondents on the specifics of the relationship between developmentally appropriate practice and gifted students who move from classroom to subject teaching within the individual curriculum, considering the gender, employment status, age and level of education of the respondents. The research used a five-point Likert scale questionnaire in which each statement was marked with 5 answers (1-I completely disagree, 2-I disagree, 3-I have no opinion/I am neutral, 4-I agree, 5-I completely agree). The questionnaire included general data on the respondents (gender, workplace/position, age, level of education) and 5 indicators of developmentally appropriate practice with a scale of indicators of developmentally appropriate practice in supporting students’ giftedness. For all indicators of teachers’ attitudes about the specificity of the relationship between developmentally appropriate practice and gifted students in sports who move from classroom to subject teaching within the individual curriculum, basic descriptive statistical parameters (arithmetic mean -AS and standard deviation -St. Dev.) were calculated and determined. To determine the statistical significance of differences between groups of respondents, the results of the t-test and analysis of variance of different groups with LSD Post Hoc comparison tests were applied. The arithmetic mean (AS) of all indicators of 3.92 shows that teachers/educators agree very well with the statements about developmentally appropriate practice. The standard deviation (SD) value of 0.82 indicates that the dispersion around the arithmetic mean is very weak, which is confirmed by the coefficient of variability (CV) of 20.92% and thus the very good homogeneity of the results obtained for this sample of respondents. The results of the T test and analysis of variance with LSD Post Hoc comparison tests indicate that there is no statistically significant difference in the attitudes of the respondents about the specificity of the relationship between developmentally appropriate practice and gifted students in sports who move from classroom to subject teaching within the individual curriculum with regard to gender, age and level of education of the respondents. The difference was determined only among the respondents with regard to employment status. In general, it can be concluded that teachers/educators have uniform attitudes about the specificity of the relationship between developmentally appropriate practice and gifted students in sports who move from classroom to subject teaching within the individual curriculum. The significance of the results obtained is that in this way, continuous and quality development of gifted students in sports who move from classroom to subject teaching can be ensured.

The study was conducted on a sample of 50 female respondents - girls from the Primary School “Sveti Sava” and the Primary School “Sutjeska” from Modriča, aged 10 to 12 years, who train volleyball in the Volleyball Club “Modriča - Novoprom” from Modriča, with the aim of determining partial and global quantitative changes in the applied morphological characteristics that occurred under the influence of a specially defined volleyball program lasting six months. The study used a set of 12 variables to assess morphological characteristics measured according to the instructions of the International Biological Program (IBP). To determine partial quantitative changes (differences) of the applied morphological characteristics, the results of the T test analysis were applied, and to determine quantitative changes (differences) of morphological characteristics at the global level, canonical discriminant analysis was applied. The results of the T test and canonical discriminant analysis show that under the influence of the programmed volleyball work for six months, statistically significant partial and global changes (differences) occurred in the space of morphological characteristics that can be attributed to the influence of the applied volleyball program, but changes in the biological growth and development of the subjects that are characteristic of the age group 10-12 years should not be ignored. The obtained results may be useful for coaches of younger volleyball selections in volleyball clubs and volleyball schools, and physical education teachers in quality programming of the training and teaching process with younger age categories of girls.

The study was conducted on a sample of 146 respondents - lower grade elementary school students, chronological age 7 - 11 years old, in the urban area of the city of Banja Luka. The total sample of respondents was divided into five subsamples according to chronological age. The main objective of the study was to determine the frequency and structure of postural disorders of the spinal column in the studied sample of subjects, as well as the differences in the prevalence of postural disorders with respect to the chronological age of the subjects, using a transversal cross-section. To assess the prevalence and differences in postural disorders of the spinal column, disorders in the sagittal plane (kyphosis and lordosis) and disorders in the frontal plane (scoliosis) were analyzed. The degree of postural disorders of the spinal column was determined using Contingency Tables - calculating frequencies (F) and percentages (%). The statistical significance of the differences in the prevalence of postural disorders of the spinal column in the sagittal (kyphosis and lordosis) and frontal planes (scoliosis) in lower elementary school students was determined using Univariate Analysis of Variance (ANOVA), and the differences in relation to their chronological age for each type of disorder were determined using the analysis of the results of the Post Hock comparison test. The degree of postural disorders of the spinal column determined by Contingency Tables - by calculating the frequency (F) and percentage (%) indicates a significant percentage of spinal column disorders (kyphosis 21.2%, scoliosis 19.9%, lordosis 19.2%), mainly in the first degree of deformation (minor deviation from the normal status), which allows for correction of the condition with the application of adequate corrective exercises in working with students of this age. The results of the univariate analysis of variance (ANOVA) show that the prevalence of kyphosis is statistically significant at the level of statistical significance p

Background: The primary goal of this study was to investigate the relationship between body composition and motor coordination performance, and the secondary goal was to determine sex differences in body composition and motor coordination of preschool children. Methods: Forty-eight children (23 boys and 25 girls) underwent assessments for body composition and motor coordination using the Köperkoordinationstest für Kinder (KTK). Results: Linear regression analysis revealed significant associations between body composition and motor coordination in boys (p < 0.05) but not in girls. In boys, Body height (p = 0.01), Total muscle mass (p = 0.03), Total fat (p = 0.03), and Total water (p = 0.02) show statistically significant influence on single-leg jumps. Similar results were obtained for lateral jumps where there was a statistically significant influence of Body height (p = 0.01), Total muscle mass (p = 0.03), and Total water (p = 0.02). Interestingly, predictive variables showed no statistically significant influence on KTK overall score in boys (p = 0.42) nor in girls (p = 0.90). Conclusions: The predictive system of morphological variables demonstrated significance only among boys in this age group and sample. Girls outperformed boys due to early maturation, resulting in better average KTK scores.

The research was conducted on a sample of 102 respondents (teachers/professors) employed in elementary schools in the Zenica-Doboj Canton of the Federation of Bosnia and Herzegovina. The main goal of the research is to determine the attitudes and possible differences in the attitudes of teachers and professors regarding the early recognition and development of athletically gifted students who transition from classroom to subject classes, in the activities that the student engages in with regard to the gender, work status, age and level of education of the respondents. As a measuring instrument in the research, a questionnaire with a five-point Likert scale was used, in which each statement has 5 answers (I do not agree at all, I do not agree, I have no opinion/I am neutral, I agree, I completely agree). The survey questionnaire contained seven indicators for the assessment of early recognition and support for the development of sports gifted students, as well as questions related to the respondent’s gender, workplace/position, age and level of education. The results of the t-test and the analysis of variance of the different groups with LSD Post Hoc comparison tests were used to determine any statistically significant differences between the groups of respondents with regard to gender, workplace/position, age and level of education. The obtained results indicate that there are no statistically significant differences in the attitudes of teachers/professors regarding the early recognition and development of athletically gifted students in the activities that the student engages in with regard to gender and age, and the differences in the attitudes of the respondents were determined with regard to work status and level of education of the respondents.

The aim of this research was to determine the structure of football through indicators of situational efficiency in world championship matches. The research sample consisted of 370 soccer players who played all 90 minutes of the Round of 16 matches of the three world soccer championships WC2010 (N = 124), WC2014 (N = 126) and WC2018 (N = 120). 30 variables of situational efficiency were used, which were taken from the official website of the World Football Federation (www.fifa.com). To determine the structure of football, we used factor analysis, the method of principal components with oblique direct oblimin transformation was used, and the Kaiser-Gutman criterion was used to determine the significance of the extracted factors. Analyzing the results, the explanation of the common variance was the highest at WC 2010 (83.52 %), followed by WC 2014 (81.97 %), and the lowest explained variance was at WC 2018 (76.30 %). In the structure of football at WC 2010 and WC 2014, 6 latent factors were singled out, and at WC 2018, 4 latent factors were singled out, which are differently saturated with situational indicators. We conclude that changes have occurred in the structure of football over a period of 8 years, which is shown by the number and structure of factors that have been fished out. The structure of football has changed in such a way that the number of factors has been reduced from 6 to 4, and the structure of isolated factors clearly defines modern football. Based on the results, the guidelines and standards on which football training should be based can be clearly determined, while using certain training tools, training stimuli and appropriate training loads in order to achieve a high level of physical preparation, a high level of technique in movement, a high rhythm of the game and tactical maturity of football players.

This research was conducted in order to determine whether and what to extent the three-month fitness program affect changjes in body composition on a sample of 42 exercisers, recreational athletes, ages between 21 and 35. The measurement was performed using a Tanita scale, model BC-543, and the following variables were applied: body weight, muscle mass and percentage of fat. After the initial measurement, a three-month fitness exercise program was applied, and then the final measurement in order to determine the achieved effects of training. Trainings were performed three times a week and were adjusted to each recreational athlete in proportion to the age and current state of training. In the process of statistical data processing, descriptive and comparative statistics procedures were used. The basic statistical parameters for each subject were calculated individually and it was determined that there are statistically significant differences between the initial and final measurements.

The research was conducted on a sample of 266 respondents of preschool age, aged 4-6 years of both sexes in Preschool Institution “Zvjezdica” Banja Luka. Out of the total number of respondents, the male population consisted of 137 respondents, while female population consisted of 129 respondents. Disorders of the knee joint, X - legs, O - legs and hyperextension of the legs were used to assess the presence of lower extremity deformities. The main goal of the research was to determine the actual state of frequency and structure of lower extremity deformities in preschool subjects in relation to gender and age. The frequencies and structure of deformities of the lower extremities are shown in tabular relation to the sex and age of the subjects. The results of the research indicate a slightly higher frequency of lower extremity deformities in boys compared to girls, and the highest frequency of presence was found in subjects of both sexes aged 4 years, and slightly lower in subjects aged 5 years. It is surprising that the presence of deformities was not determined in subjects of both sexes aged 6 years. However, these results also oblige us to be careful and constantly and continuously monitor the postural status of children in order to timely identify physical disorders and take adequate activities in preventive and corrective work. The obtained results should initiate activities in order to timely diagnose, control and undertake effective programs of corrective exercise in preschool children.

The research was conducted on a sample of 70 respondents-swimmers aged 13-15 years of swimming clubs from Sarajevo Canton/Federation of BiH, with the aim of determining the significance and magnitude of the impact of selected basic motor skills on the implementation of specific motor tasks in swimming (navigability in place, sliding length with reflection from water, start from starting block, parallel). The study used 10 variables to assess basic motor skills, which were the input or predictor set of variables, and three variables to assess the efficiency of specific motor tasks in swimming as a criterion, each variable from the battery of specific motor tasks was considered as a criterion on the predictor set of basic-motor variables. Three mini regression analyzes were applied to determine the statistical significance and relative influence of basic motor skills on the realization of specific motor tasks in swimming (buoyancy in place, length of sliding with reflection from water, start from the starting block, parallel). The results of regression analyzes indicate that the greatest influence on the overall efficiency in the implementation of specific motor tests in swimming, looking at all criterion variables together, from the set of basic-motor variables, as a predictor set, show the following variables: stick twist-MFLISK MFLPRK, plantar flexion-MFLPL, long jump from place-MFESDM, agility on the ground-MKOKNT and shelter in lying-MRCZTL. The results obtained in this research can be useful for teachers and swimming trainers who work with younger age categories for the purpose of better programming of training work and selection of training content.
