The World Health Organization (WHO) released guidelines for physical activity (PA), sedentary behavior, and sleep for children under 5 years of age in 2019, but there are no reports on the adherence to the guidelines in southeastern Europe. This study aimed to: (i) determine the proportion of preschool children (aged 3-5 years) who met the WHO guidelines and examine the feasibility of the proposed protocol for the SUNRISE study in Bosnia and Herzegovina (B&H), and (ii) define sex-, and urban/rural-living-specifics in movement-behaviors, anthropometrics, gross-motor-skills, fine-motor- skills, and cognitive-skills. The sample comprised 115 preschool children (63 girls and 52 boys), residing in urban (n = 66) and rural areas (n = 49) from B&H. Participants were tested on movement behaviors (PA, sleep time, screen time) by accelerometry and comprehensive questionnaires. Body height, weight, body mass index, executive function, fine-, and gross-motor skill, and cognitive function were also measured. The results showed that PA-, sleep duration-, and screen time guidelines were met by 64%, 74% and 53% of children, respectively, while only 23% of the children met all three guidelines on movement behaviors. Boys exhibited higher PA than girls, but no differences in gross- and fine motor skills and cognitive functioning were recorded between the sexes. Children living in urban and rural environments did not differ in any of the studied variables. Results evidenced preschool children from B&H being in line with other samples globally about study variables. Although PA was higher in boys than in girls it was not translated to differences in motor skills. Further studies on larger samples and other environments are warranted.

The World Health Organization (WHO) released guidelines for physical activity, sedentary behav-iour, and sleep for children under 5 years of age in 2019. In response to these guidelines, this study aimed to determine the proportion of preschool children (ages 3-5 years) who met the WHO guidelines. The time spent in physical activity, sedentary behaviour and sleep were objectively measured using accelerometer (ActiGraph wGT3x-BT). Screen time and sleep quality were assessed via parent questionnaire. Focus groups were con-1 ducted with parents and childcare staff to determine the feasibility of the protocol. The results showed that only 23% of the children met all three guidelines, and compliance rates varied for each guideline. The physical activity time guideline was met by 64% of children, the sleep duration guideline was met by 74% of children, and the screen time guideline was met by 53% of children. Only a low proportion of children met the WHO guidelines. The methods and devices used in this pilot study proved to be feasible and this has paved the way to conduct the main SUNRISE study in Bosnia and Herzegovina.

The goal of this research is to evaluate the effects of applied kinesiological activities of different extensions on the transformation of basal-motor abilities of boys. The sample of respondents is represented by boys, students of VII, VIII and IX grades of primary school. „21. March "Matuzići - Doboj South. The total sample consists of a set of 76 respondents classified into three distinct groups. Based on the boys' statements about their participation in everyday physical activities, groups with the numbering were defined through non-athletes: non-athletes-1, recreational athletes-2 and athletes-3. To assess the basic motor skills of the respondents, the variables according to the Eurofit battery test program were used, as follows: Flamingo balance, endurance in the joint, lying-sitting, running 10 × 5m (back and forth), hand tapping, hand dynamometry, flexibility-mobility at the hip joint, jumping away from the spot and running 20m back and forth with progressive acceleration. The results of univariate covariance analysis showed high significance in endurance assessment tests (SHATL 20 and SHATL 10 × 5), followed by static arm strength (MSSIZG), and hand strength (MSSDIN) and torso flexibility (MFLPRK) and balance (MRFLAM). Statistically significant differences in effects did not occur with the three variables, namely hand tapping ( MBFTAR), long jump (MESSDM) or squat-sitting (MRSLSJ).

Background: The novel coronavirus disease 2019 (COVID-19) seems to be having a significant impact on physical activity behaviors globally. The pandemic has forced many of us around the world to remain reception and self-isolate for a period of your time. Aims and Objectives: The aim of this paper was to find out how much the measures due to the COVID-19 pandemic affected the daily lives and how the measures affect the physical activity and mental health of students after 81 days. Materials and methods: A total of 67 participants have answered the questionnaire. The participants were 48 (71.6%) males and 19 (28.4%) females. The mean age of all participants 22.28 years. Study Design and Setting: The questionnaire is divided into several different chapters: personal characteristics, sleep habits, level of physical activity, social functioning and viewing habits, general health condition, COVID-19. Statistics: Statistical differences between male and female students were tested using the chi-square test and t-test. A p-value of < 0.05 was considered statistically significant. Results: Inactivity had a more negative effect on the male population than on women. In this article, the author will highlight the potential impact of the COVID-19 outbreak on the physical activity and mental health of students. The data showed that the COVID-19 pandemic lockdown affected the academic performance of most participants. Conclusion: Home-based activities provide an opportunity for students to stay fit and healthy by practising simple movements while staying at home without the usual student obligations. We see that student confinement did not affect both sexes the same.

This study was conducted on a sample of 40 senior and junior male and female karate fighters, chronological ages 18 to 27 from the Tuzla Canton, who are part of the regular training and competition process. The aim of this paper is to determine the differences in the motor reaction speed among the karate players with the same specializations but at different levels of competition, in conditions of fatigue induced by intense physical work in combination with complex visual signalization, which determines certain karate techniques. The study was conducted with the application of sophisticated technologies used in sport that enable the collection of data. The light stimuli was generated by the usage of the RIR 102 reaction meter and the quantitative valorization of the investigated parameters was carried out by a sophisticated kinematic analysis of the videos collected using two high-speed Casio Exilim EX-F1 digital cameras synchronized with the data from the Polar Team heart monitoring system. By processing and analyzing data, it was concluded that fatigue induced by situational conditions such as performing a series of strikes that simultaneously generate muscular, cognitive and sensory strain, produces negative effects on reaction time of the karate players. The intensity of limiting factors grows gradually in function of time, but is manifested differently in relation to the international and state level of competition.

Background: Physical inactivity and intensive sports activity have been found to be associated with LBP. The aim of this study is the presents the data about the prevalence of LBP in young adults and its associations with vitality, physical activity and emotions. We also studied the impact of low back pain on daily activity. The study sample presented (n=323) students from the Former Yugoslav Republic of Macedonia and Bosnia and Herzegovina in the chronological age of 21.06 ± 1.93 years. The current study assessed the level of LBP amongst students of Faculty of Sport with the level of physical activity in last six months. Methods: We used the questionnaire, which included the Graded Chronic Pain Scale (GCPS) for the evaluation of levels of chronic pain. With a Short Health Survey (SF-36) we tried to measure the health status. Results: A total of (n=323) of all students had pain intensity at some point in last six months. All students reported (n=236, 73.0%) prevalence of LBP. In this study body mass index, level of physical activity were not significant independent predictors of intensity and disability scores. Conclusion: 3/4 of all respondents said to have had any episode LBP. The results of our study can be used by officials in the area of prevention to support efforts to improve health of the student population and to reduce the LBP risk.
