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.

Explosive power is the dominant motoric ability in most sports, regardless of the age, gender and level of the competition, and as such participates in the equations of the specification. Vertical jump (Squat Jump) is a test for estimating the explosiveness of caudal extremities in a number of sports, most often in football, athletics, basketball, volleyball. The study included a sample of 39 respondents (19 cadets, ages 15 ± 0.5 years and 20 juniors, age 17 ± 0.5 years). The aim of this study was to determine the differences in the strength of the leg springs between players of junior and cadet ages. For the estimation of explosive power, the Squat Jump was measured using the Chrono Jump contact mat tensiometric platform (Bosco System, Spain). The analysis of the T-test showed statistically significant differences at the level of p <0.000 in favor of boys of junior age. Article visualizations:

The purpose of the study was to explore the possibility of creating a valid and reliable model and instrument for measuring physical and health education teachers’ competences in classroom education process, perceived from the perspective of secondary schools students. Also, the goal was to explore to what extent official legislative documents as well as official curriculum of the Faculty of sport, health and physical education in Sarajevo represent a sufficient background for creating such a measuring instrument with satisfactory metric characteristics. The sample in this study were N=831 students from fourteen secondary shools in the urban parts of Sarajevo. The students attended third (N=422 or 50.8%) and fourth class (N=409 or 49.2%) at the time of the research. There were N=452 (54.4%) females and N=379 (45.6%) males in this sample, both aged from sixteen to eighteen. An analysis of legislative documents and the official curriculum was conducted by a group of education experts in order to establish the indicators of psysical and health education teachers’ competences and to design an instrument to register and measure these competences. Finally, a 28-item Teachers’ Competences Perception Questionnaire was constructed (TCPQ)and applied on the given sample. The results of Exploratory and Confirmatory factor analysis showed that the questionnaire measured five distinct and correlated factors and they are (1) teaching competences, (2) communication and empathy, (3) health care instruction, (4) pedagogical competences and (5) physical appearance of a teacher; these five factors explained 57.726% of total variance indicating a solid factor structure of the instrument. Oblimin rotation also yielded a meaningful factor solution following the frame of the Curriculum and Legislative documents’ content related to physical, health and sports teachers’ competences. Reliability analysis showed satisfactory reliability of the most of the factor scales. Implications for the use of the questionnaire on the students’ populations, as well as the possibilities for further instrument development and curriculum modification are stated on the account of the research results.

The purpose of the study was to examine if there are significant differences between male and female secondary school students in assessing the personal and professional competences of their physical education teachers, and to determine if these group differences are in any kind of interaction with the teachers’ gender. The sample in this study were N=831 students from fourteen secondary schools in the urban parts of Sarajevo. The students attended third (N=422 or 50.8%) and fourth class (N=409 or 49.2%) at the time of the research. There were N=452 (54.4%) females and N=379 (45.6%) males in this sample, both aged from sixteen to eighteen. A 28-item Teachers’ Competences Perception Questionnaire was constructed (TCPQ) and applied on the given sample. The instrument measured the competences related to teaching skills, communication and empathy, health care instructions, pedagogical competences and physical appearance. According to the results, the male students gave higher ratings to the teachers of both genders on pedagogical competences. No significant group differences and interactions were identified on all the other competence scales. Also, the students of both genders generally gave higher ratings on physical appearance to female teachers and a significant positive interaction was found between student and teacher gender in assessing the teachers on this variable. Finally, a negative interaction was found in assessing teachers on communication and empathy where male students rated female teachers higher and female students rated male teachers higher on this variable. Theoretical and practical implications of the study have been also

The aim of this study is to determine the deformation of the spinal column at the school for students of classroom teaching. The research was conducted on a sample of 1,105 students, of which 563 boys and 542 girls, aged 5-12 years. In the program of research were involved students from first to fifth grade in eleven elementary schools in Sarajevo: ES "Kovačići" PS "Behaudin Selmanović" PS "Sokolje" PS "Dobroševići" PS "Safet beg Bašagić" PS "Zahid Baručija "PS" Fatima Gunic "PS" Aleksa Santic "PS" Avdo Smailović "PS" Mehmedalija Mak Dizdar, "PS" Hamdi Kreševlajković". To determine the deformation of the spine column, we used the method of measuring the curvature of the spinal column by criteria Napoleon Wolanskog the (1975) year.
