This research aimed to determine effects of individual fitness programs on power increasing of dynamic knee stabilizers in student population. Respondents who participated in the research were 110 male students from Faculty of Sport and Physical Education in Sarajevo. They were divided into two groups. an experimental and a control group. Maximum strength of dynamic knee stabilizers was tested on an isokinetic apparatus (Biodex System 3) with angular speed of 60°/s. The experimental group conducted additional individual fitness program three times a week in the period of 12 weeks. Obtained results lead to the conclusion that individual fitness programs produced significant effects on development of maximum strength of dynamic knee stabilizers and that those results are statistically significantly different from results of the control group which only practiced regular study program classes.

Abstract The aim of this study was to explore the association between leisure time physical activity, socio-demographic characteristics and the levels of perceived stress. The study included 300 respondents who were divided into two groups: high levels of perceived stress (n=150) and low levels of perceived stress (n=150). Levels of perceived stress were assessed using the Perceived Stress Scale-10.Data concerning leisure-time physical activities and socio-demographic characteristics were collected using a designedquestionnaire. Age between 46-64 years (OR=5.63, 95%CI=1.02-2,55; p=0.00), financial status as worse than average (OR=2.29, 95%CI=1.39-3.76; p=0,00) and female gender (OR=1.62, 95%CI=1.02-2.55; p=0.03) were positively associated with high levels of perceived stress. The currently recommended weekly volume of ≤1150 minutes of physical activity of moderate intensity in leisure time had a protective role against a high level of perceived stress (OR=0.44, 95%CI=0.25-0.77; p=0.00). Therefore, we conclude that promoting the currently recommended volume of physical activity might be a good way to increase overall physical activity levels and reduce a perceived stress among population groups at risk for high levels of perceived stress specifically, as well as the general population.

The problem of this research is: what is the characteristic of the speed of individual hand movements, and how to change the response time in children aged 8 to 14 years? The aim of the study is to determine the response time i.e. the speed characteristics of individual movements of the dominant hand, the non-dominant hand and the dominant hand with the fencing foil in relation to age. The hypothesis is that maturation affects the speed of individual hand movements and the simple reaction time (SRT) i.e. response time.The sample consisted of 184 subjects aged 8 to 14 years. The study used the one-target shot - Electronic Fencing Target on the Favero Scoring device. The speed of individual movement of the dominant hand (Dom_H), the speed of individual movement of the non-dominant hand (NDom_H) and the speed of individual movement of the dominant hand with fencing foil (Dom_H _F) were tested. Multivariate analysis of variance (MANOVA) found that the criterion of age, or maturation, has statistically significant influence on the speed of individual hand movements (Wilks' Lambda = 0.519; F = 4.105; p = 0.000). The highest maturation effect was found in the speed of individual movement of the dominant hand with fencing foil (Dom_H_F - F = 6.923; p = 0.000; PES = 0.289), while in the Dom_H test (F = 4.782; p = 0.000; PES = 0.220) and NDom_H (F = 4.671; p = 0.000; PES = 0.216) was found a slightly lower effect. Maturation has a positive effect on the speed of individual hand movements in children aged 8 to 14. The effect is the highest when the fencing foil is used.

Game is a module of human activities that follows an individual since his/her earliest development. Games are also first level of children's active function and includes many elementary ways of movements (walking, running, jumping...). Games are activities familiar to children and while playing, they are spontaneously discovering new things. Proper body posture is a sign of good health, regular growth and development so it is important to emphasize body posture from the earliest age by applying different ways of physical activity. Aim of this research is to determine influence of games as activities to components of body posture of school children. This research was done to determine role of games within prevention of correct body posture of primary school students. Research samples were 62 class teachers employed in 5 primary schools (Municipalities: Breza, Vareš, Ilijaš, Visoko). Data which defined role of games within prevention of correct body posture of primary school students was gathered by filling anonymous survey containing six different questions. After data was collected, theoretical method, descriptive-analytical method and empiric-no experimental method (survey) was used. Analysis of the results have shown that games mostly influence regular growth and development of students in lower grades since then games are the most frequent type of activities, 21 teachers (33,87%) recognized game as being the most important factor on regular development from first to fifth grade students. The same number of teachers recognized that games mostly influence development of first graders and contributes to regular and normal growth of child's organism. Such regular development can be seen in physical, psychological, social and emotional aspect. 59 teachers (95,16%) think that games influence all body segments and as such influences correct body posture of students in lower grades of primary school. Basis of this research was to determine role of games in prevention of regular body posture in primary school students. Based on teachers' opinions, games have preventive impact on regular body posture within students from 1st to 5th grade of primary school.

The aim of this research was to determine the effects of small-sided games and interval training on vertical jump, speed and change of direction speed in adolescent soccer in adolescent soccer players. A total of 60 young male soccer players (aged 14–18 years) were recruited. Players were assigned to small-sided group (SSG), or high intensity interval group (HIT) during the last 8 weeks of the season. Physical performance tests included a squat jump (SJ), countermovement jump (CMJ) countermovement jump with arm movement (CMJAM), 5-m, 10-m and 20-m sprints and illinois test. HIT was performed over 40-m shuttles, with 15s-15s, intermittent runs. And for the SSG programme a team size of 3 or 4 players was used on different pitch size. Both groups improved in the 5-m sprint (p ˂ 0.05).There was a significantly greater improvement in the 20-m sprint (p ˂ 0.05, large effect), Illinois (p ˂ 0.05, large effect), SJ (p ˂ 0.05,moderate effect), and CMJ (p ˂ 0.05, large effect) following the HIT training compared with the SSG. To conclude, during the last weeksof the season, HIT training improved or maintained fitness status in adolescent soccer players. On contrary, SSG training seems to only maintain or even decrease the physical performance in the end of the season among adolescent soccer players.

Starting to study at the University and getting new responsibilities changes the way of lifestyle. The change is mostly maintained in the way of eating and (non) existence of physical activity. The aim of the research was to determine the food habits and physical activity of the students at the University of Sarajevo. The study covered 1038 (694 female and 344 male) students from 1st to 5th year of the faculty, 18 to 43 years of age. Used method was a questionnaire designed for this research, and based on previously used questionnaire and it was conducted online. Results show that the largest number of students (48.0%) consume 2 meals a day, 81.9% of students thinks that the breakfast is the most important meal but only half of them (53.7%) always have breakfast. 37.2% of students usually have eggs for the breakfast, 30.8% sandwich, 19.9% slice of bread with toppings and 12.1% eat cereals. 11.4% of students carry a meal from home: 11.1% take fruits and 35.4 % take the sandwich. 89.2% of students buy snacks in fast food and bakery: hamburger (60.0%), sandwich (33.0 %), hotdog (6.7 %), croissant (38.1 %), dough with cottage cheese (27.0 %), pie (17.5 %), dough with the hotdog (11.1 %). Most of the students (62.5 %) consume water, 5.8% drink juice, while 31.7% consume both. 65.2 % are involved in physical activity 1-2 times weekly for 30 minutes, 34.3 % are involved 2-3 times a week for 60 minutes and 66.1 % of student are physically active every day for 90 minutes. Those who are not active „blame „insufficient leisure time (48.1%), obligations at the faculty (39.6%), lack of money (12.3%). Most of the students (33.7%) sleep for 8 h, 32.3% sleep for 7 h, 24.5% sleep for 6 h. Conclusion: Inadequate eating habits, insufficient time and too much obligations, but also a high percentage of students involved in physical activity and enough sleep, points the need to open students' canteens based on the principles of proper nutrition and tailored to students' income.

Family and school partnerships are important for achieving quality results in education and this research is a transient partnership study. In our research, we investigated the communication and participation of parents in decision-making, since both are seen as elements of active parent involvement in building mutual partnership. The purpose of the paper was to examine the impact of an experimental treatment on the development of parent-school partnership in relation to sex and professional qualifications. In this research we used methods: analytical-descriptive method, theoretical analysis method, survey method and experimental method. Parents were interviewed with the same questionnaire before and after experimental treatment (partnership workshops). The research sample consisted of thirty parents of high school students (14 females and 16 males) in the territory of Travnik Municipality. Results of the T-test were statistically significant differences (p=0.05). There is a statistically significant difference for male (t=-4.824; p=0.00) and female subjects (t=-5.192; p=0.00) between the initial and final survey. The differences may be seen in the case of subjects who have elementary education (t=-6.504; p=0.00) and secondary education (t=-5.276; p=0.00). In the case of subjects with university education (t=-2.138; p=0.07), these differences are not statistically significant.
