Aim of this research was to determine the effects of specific programmed training on morphological characteristics, motoric and functional abilities of elite judokas. Seven judo athletes (24.71±3.35 years), that have won at least one medal in the European Judo Championship or in the World or European Judo Cup during previous two years participated in study. The sub elite group consisted of 7 athletes (26.14±3.39 years) that have only won medals in national competitions (Bosnia & Herzegovina). Skin-fold (suprailiac) was significantly reduced in experimental group after the applied treatments (F = 5.38, P = 0.039). Furthermore, significant interaction effect appeared (F = 6.94, P = 0.022), which indicates significantly greater effect on the increase in volume of Right forearm in the experimental group after applied program, whereas in the control group, these values had smaller average size in the final measure- ment. Bench Press (F = 121.00, P = 0.000), Deep squat (F = 14.03, P = 0.003), Dead lift (F = 27.56, P = 0.000) and Hand Grip Right (F = 22.91, P = 0.000). In variables of power evaluation effects of applied treatment were also significantly better in favor of experimental group with Single high jump (F = 10.48, P=0.007), Single long jump (F = 12.79, P = 0.004) and Medicine ball toss (F = 47.25, P = 0.000). After six months of applied training protocol, regarding anthropometric measurements in experimental group of judokas, at the same time occured a reduction in the percentage of fat and suprailiac skinfold as well as an increase the of the right forearm circumference at a significant level of deduction. Furthermore, the significant increase in all variables of strength and coordination is noticable. The experimental treatment also resulted in a significant increase in aerobic and anaerobic power, as well as judo-specific fitness, whereas no significant changes were occured in flexibility variables and left-hand grip.

The aim of the paper is to verify the validity and reliability of Scale for measuring tactical and technical competences among football players - assessment of trainers (STTSKT). The research involved 165 players (N = 81 senior and 84 juniors) from seven junior teams and senior Premier League Bosnia and Herzegovina. The average age of the participants is 21.14 ± 4.91; The average age of the junior is 17.23 ± 0.49, while the average age of the senior is 25.15 ± 4.21. The analysis of the main components points to the existence of two factors which in total explain 68.874% of the variance of the specific competence skills of football players. According to the grouping of particles, the first factor was called the attack tactical-technical competence (NTTK); other one are defence tactical- technical competences (OTTK). The reliability of the instrument is determined by the coefficient of internal reliability. The obtained number of factors is not in accordance with the obtained factors on the Scale for assessment of tactical and technical competences among football players (STTSK), which was designed as a self-assessment of the competence of football players. Values of alpha reliability coefficients for the full scale and for subscales are high. The results point to the conclusion that the STTSKT scale possesses satisfactory metric characteristics, and that the trainers can use it as a measure of specific competencies among football players.

Abstract Based on the theoretical analysis and the present findings of the research on psychological factors that contribute to the successful implementation, we have designed this research project in order to integrate the knowledge of the Five-Factor Personality Model (Mc- Crae and Costa, 1992), which is the starting point for the Hypothetical model of success in team sports (Mlacic and associates, 2010), and self-efficacy (Bandura, 1986) and the locus of control (Rotter, 1971), which are important determinants of individual characteris- tics of sportsmen and their contribution to successful sport. Therefore, the aim of this research is to test the contribution of individual psychological features (neuroticism, extraversion, agreeableness, openness to experience, conscientiousness, self-efficiency, locus of control and length of football training as one of the experience traits), in explaining the success of football players. The research involved 165 football players from six football clubs in Bosnia and Herzegovina. For the evaluation of the predictor variables it is used a questionnaire on general data of footballers; The NEO-PI R (Coste and McCrae, 1992) was used for the examination of Five Personality Factors, and the Scale of self-efficacy of footballers was used to examine self-efficiency in football (Samija and Bosnar, 2010) while the Scale of externality was used to examine the locus of control (Bezinovic, 1990). The assessment of the performance of footballers operating through the Scale for the assessment of technical-tactical and social competencies of football players- STTSKT (Setic, Kolenovic-Dapo, Talovic, 2017) has conducted 14 trainers. In order to check the contribution of the predictor variables of individual psychological characteristics in predicting the individual success of footballers (STTSKT), we conducted a process of hierarchical multiple regression. According to logical and content characteristics, we have introduced the predicate variables into the two blocks; in the first block there is a personality trait of the Five-Factor model, and in the second block is self-efficacy, locus of control and experience. The individual characteristics of the dimension of the personality of the Five-Factor model explained 6.6% of the STTSKT variance, and after we included the perceived self-efficacy, locus of control and expe- rience in the second step, the model explains 13.3% of the total variance. The model as a whole with both blocks of individual features is significant F (8.136) = 2.597, p <0.01. Of all predictive personality variables, only perceived self-efficacy significantly contributes to predicting success in football (t = 0.251; p <0.05).

Research is done to determine different structures of Physical Education lessons given the fact that lesson style has significant impact on the entire pedagogical flow within teaching process. Examinee samples were taken from students of seventh and eighth grade of primary schools in Canton Sarajevo. 514 examinees were included in survey, 53% male students and 47% female students. Data was gathered by filling out the survey of 17 different questions - variables. The aim was to identify work methods of the teachers during the lesson. This type of data is very important since work methods determine pedagogical climate and teacher - student interaction during Physical Education lessons in primary school. After the research, analysed results have shown that first extracted latent com- ponent with characteristically root of 5.133 and 43 percent of the overall explained variable previews democratic behaviour of teachers. For the other isolated latent component with characteristically root of 2.441 and 20 percent of overall variable previews ,,lessees fair "work methods. Third isolated latent component with only 12 percent of explainable variable is practically mathematical artefact. This is confirmed by isolated characteristically root whose value is 1.452. So, this component clearly states these are work methods of so called autocratic teachers. Recommendation for researchers who want to investigate similar themes is to evaluate teachers of Physical Education in High School. In following researches, information could be distinguished according to sex of the students and compare eventual differences of interpreting teachers' methods during the lesson.

The aim of this research was to examine the predictions of vocational outcomes of junior karatekas based on the constructs of the most important self-evaluation and self-efficacy in expectations regarding their vocational outcomes. This research included 204 karatekas from Serbia (AM = 16.42, SD = 1.06). Three measuring instruments were applied on this pertinent sample: Core Self- Evaluations Scale, Career Decision Self-Efficacy Scale (CDSES-SF) and Vocational Outcome Expectations Scale (VOE). The internal consistency and reliability of the used scales was in accordance with the theoretical statistical reliability criteria. The values of Crombach alpha coefficients were (α = 0.82, α = 0.90, α = 0.88), which points to homogeneity among the items. The conducted model of hierarchical regression analysis determined that the variables: a) the most important self-evaluation and b) self-perceived career decision self-efficacy, are statistically significant predictors of the criterion of karatekas’ vocational outcome expectations, which accounted for 66% of the variance of criterion variable (R2 = 66%, p < 0.01). At the same time, the partial contribution of the construct of core self-evaluation was mediated by the

Aim of the study was to determine differences between defined quality groups of students according to the body mass index (BMI), in their motor-functional status tested by certain athletics disciplines. The sample consisted of 24 students (age = 19 ± 0.78, height = 183.3 ± 6.96, body mass = 77.7 ± 10.24) who completed the study course of Athletics at the first year of the Faculty of Sports and Physical Education, University of Sarajevo. Used variables consisted of the following athletics disciplines: sprint running 60 m, hurdles running 60 m, running 300 meters, long jump and shot put. The sample was clustered into three equal groups consisting of 8 students, according to the BMI criterion [Group 1 BMI = 20.3 kg/m2 (181.3 cm, 67.1 kg); Group 2 BMI = 22.8 kg/m2 (186.5 cm, 79.3 kg); Group 3 BMI = 26.1 kg/m2 (182.1 cm, 86.8 kg)]. Analysis of the results in athletic disciplines showed statistically significant differences in variables of running at 300m (1st with 3 – p=0.040 and 2nd with 3 - p=0.049), long jump (1st with 3rd p=- 0.043 *) and shot put (1st with 2nd p=- 0.049 *). The obtained results indicate that motor-functional status of students was primarily differed by the level of anaerobic-aerobic and anaerobic potential, according to the type of speed-endurance, speed-strength and explosive-strength.

The aim of this study is to determine levels of anthropometric features and to make comparison to training status in football and basketball players. In total 53 football and 47 basketball players, who play in the clubs of the Premier League of Bosnia and Herzegovina. Body weight, height, 6 skin folds and 4 volumes were measured. An independent t-test showed that the difference in mean body height between the football and the basketball players was statistically significant (p<0.001), the average difference in height was 8.7 cm in favor of the basketball player, while the differences in the mean values of the body mass were not statistically significant (p=0.07). BMI was statistically significant (p= 00017) with higher BMI for football 22.8 ± 1.4 kg/m2 compared to 21.2 ± 5.7 kg/m2. In relation to age, statistical significance in mean body weight and body height was not observed, while BMI differed (p=0.001). Juniors have lower BMIs, (21.67 ± 2.4 kg/m2) than the seniors (23.08 ± 1.67 kg/m2), which can be explained by the fact that seniors have trained for longer and have less fat in total body mass. A statistically significant difference in the median values of the subcutaneous fatty tissue, as well as the extent of the extremities between football and basketball players, was not established, but significant differences were found in relation to age. The study showed that there is correlation between years of training and body weight (r = 0.209, p=0.037), longer training time is associated with higher body weight. Training years were also correlated with BMI (r=0.385, p<0.001), athletes who train longer have higher BMIs. The training years correlates with percentage of fat % (r =-0.337; p = 0.001.), with a longer training time, the percentage of fat tissue in the total body mass decreases.
