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.

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.

The aim of this research was to determine the influence of motor abilities on the success of performing a freestyle swimming, pre and post the completed swimming training program. The study was conducted on a sample of 90 female students, aged 11-12 years, fifth graders from primary schools in Novi Grad Municipality in Sarajevo, using 6 motor variables and 1 criterion. Regression analysis was used to determine the effect of balance and flexibility on the freestyle swimming performance. Analyzing the presented results of the regression analysis, it was found that after the pre-test measurement of the variables for estimating the balance, the following predictor motor variable had the greatest and statistically significant influence on the criterion variable: standing upright on the balance beam with eyes open (BETA) = .581, which is significant at the level of p<.001. For flexibility, the following predictor motor variable is: upper body bent forward while sitting with legs side by side (BETA) = .411, which is significant at the p<.001 level. After the post-test measurement of the variables for the assessment of motor abilities (balance and flexibility), the same variables as for the pre-test measurement had the statistically significant influence on the criterion variable (freestyle swimming of the sections 25 m long – crawl, chest or back swimming). At standing on the right leg longitudinally, open-eyed, on the balance bench (BETA) = .448, which is significant at the level of p<.001, and in flexibility the variable - bench ab with legs side by side (BETA) = .463, which is significant at the level of p<.001. All movements in swimming require well-developed flexibility (mobility), and in particular the mobility of the torso and upper extremities.

Purpose: Determining the state of the student and his situational-motor skills, and their comparison, enables the teacher to control his work in an immediate manner, and he programmes and implements well planned and additional contents in order to realize the set goals. In order to achieve these functions, it is necessary to determine the current state of the students, as well as the state after the implemented specific contents and programs. The aim of the research was to determine the partial changes (differences) of situationalmotor abilities that were created under the influence of a four-month program of basketball, volleyball and handball in the pupils of the fifth grades of elementary school. Material: The study included N = 106 class V students, aged 10 to 11 years. The sample of respondents was divided into two subgroups, an experimental group (53 students), who conducted physical and health education classes according to the modified plan and program of sports games (basketball, volleyball and handball) for a half-year and control group (53 students) who attended regular classes from physical and health culture according to the current curriculum. 9 variables were used to assess situational-motor abilities. Descriptive statistics and discriminatory analysis were used to determine the changes (differences) in situational-motor skills. Results: The results of the research at the descriptive level showed certain differences between the groups in the final versus the initial measurements on the individual variables of situational motors. Based on the results of the discriminatory analysis, the relative contribution of each of the variables of the situational motor in the final measurement is seen. The SMKVLS (Running the ball with your hand in the slalom) and SMRBLZ (Throwing the ball against the wall for 30 seconds) variables are the biggest contributors, and the smallest SMOGCPM (Aiming the goal over the net from the basic stand) and SMOSD (Lower frontal serve). Conclusions: Physical and health culture in schools has the primary task of influencing positive transformation processes in all dimensions of students by applying appropriate content.

The aim of the research was to determine the effects of specially programmed physical and health education with the application of content from sports games (basketball, volleyball, and handball) in the duration of one semester to qualitative changes in situational motor skills in students in the fifth grade of elementary school. The study included 106 pupils of the V class, aged 10 to 11 years, clinically and mentally healthy, and with no pronounced morphological and locomotor impairments. The sample of respondents was divided into two subgroups, an experimental group (53 pupils), who carried out physical education classes according to the modified plan and program of sports games (basketball, volleyball, and handball) for a semester and a control group (53 pupils) who attended regular classes from physical education according to the current curriculum. In order to determine qualitative changes in situational motor abilities, descriptive statistics, T-test, and factor analysis were used. The results of the factor analysis show that there were statistically significant qualitative changes, and based on the results of t-tests it can be concluded that they are statistically significant at levels less than 1% for the SMKVLS variable, and at levels less than 5% for the variables SMRBLZ and SMRVLS. In the final measurement, there was a change in value and thus a difference in the variables of the SMKBLK after the program of work.

Purpose: Thanks to the positive health effects of physical exercise, physical education is an integral part of the education system, with two hours per week, which is insufficient to achieve an optimal effect in transforming the anthropological status of children. The aim of the research was to determine the effects of regular and modified physical education with the application of contents from sports games (basketball, volleyball and handball) in the duration of one semester to changes in basic motor skills in pupils of the fifth grade of elementary school. Material: The study included N = 106 students of the V class, aged 10 to 11 years, clinically and mentally healthy, and with no pronounced morphological and locomotor impairments. The sample of examinees was divided into two subgroups. The first was an experimental group of 53 students, who carried out physical education classes according to the modified plan and program of sports games (basketball, volleyball and handball) for a semester. The other was a control group of 53 students who attended regular classes from physical education according to the current curriculum. Results: The results of the research at the descriptive level showed noticeable differences between the same groups in the final versus the initial measurements. Based on the results of the t-test for the control and experimental group, it can be concluded that there have been statistically significant changes in values on all variables of basic motor in the final compared to the initial measurement. By analyzing the results of the t-tests, it can be seen that the groups differ in the initial measurement only in one basic motor variable, MTAPN, and this difference is statistically significant in favor of the control group. In the final measurement, there are no significant differences between the control and the experimental group in the average values of all variables of basic motoring. Conclusions: Improving basic motor skills depends on the teacher's ability, the ability to transform the age with which he is working, and the success of certain training processes. The modified program of the experimental group has led to changes and thus proves the significant effect of the group's work program.

The aim of this study is to determine the influence of motor skills (repetitive strength and coordination) on the success of performance freestyle swimming before and after the completed swimming training program. The research was conducted on a sample of 90 students, both male and female, aged 11-12, the fifth grade of primary school students from Novi Grad municipality in Sarajevo, with 6 motor variables and 1 criterion variable. A regression analysis was used to determine the effects of repetitive power and coordination on the performance of freestyle swimming. By analyzing the presented results of the regression analysis it can be concluded that after the initial measurement of the variables for the repetitive power estimation, the most important and statistically significant influence on the criterion variable OCJTEH had the following predictor motor variables: MRSDTZ (BETA) = 0.217, which is significant at p = 0.033, MRSSKL (BETA) = 0.285, which is significant at p = 0.007, MRSDCU (BETA) = 0.383 which is significant at p = 0.000, and in coordination the following predictor motor variables: MKOPRP (BETA) = 0.393, which is significant at p = 0.001, MKOPRL (BETA) = 0.198, which is significant at p = 0.049, MKOOUZ (BETA) = 0.268 which is significant at = 0.004. After the final measurement of the variables for the assessment of motor abilities (repetitive forces and coordination) the most significant influence on the OCJTEH criterion variable (swimming for 25 m free technique) had the same variables as in initial measurement: at repetitive force variables – MRSDTZ, MRSSKL, MRSDCU, in co-ordination variables – MKOPRP, MKOPRL, MKOOUZ.

The goal of this research is to determine the differences between spinal deformities of students in urban and rural areas with regard to the initial and final measurements. This research was conducted on a sample of 1105 students. This research program includes students from the first to the fifth grade in the following 11 elementary schools in Sarajevo. Method of measuring the curvature of the spine based on Napoleon Wolanski ’ s criteria from 1975 entitled D-5 spine posture (ESP). The analysis of spinal deformity of students in urban and rural classrooms was done by using the descriptive chi-square statistics. It has been determined that in the initial measurement, a greater number of examinees with no spinal deformity came from the rural schools. The examinees from the urban schools displayed first- and second-degree spinal deformity. In the final measurement, a greater number of examinees without spinal deformity came from rural schools, 28 (2%) to be precise. There was also a greater representation of first-degree spinal deformity in the examinees from urban schools, 49 (8%) to be precise. However, the representation of second-degree spinal deformity was not present in either of the examinees from rural or urban schools.
