The aim of this study was to show the extent of the influence of the shift work on nutritional status and physical activity of police officers. The research included 130 healthy police officers. The respondents were divided into two groups. The first group included 82 officers who were working the first shift. The second group included 48 officers who were working the 12hour shift. The study used customized questionnaire consisting of questions regarding leisure-time physical activity, self-report lifestyle activity level, body height, body mass, and derived body mass index (BMI). The ANOVA analysis showed that the first shift had significantly lower BMI (2.57 kg/m2 , p = 0.004) than the 12-hour shift. The results showed that physical activity is strongly associated with lower values of BMI in both groups (p < 0.01). Regarding the correlation between age and years of service, only the 12-hour shift showed coherency (p < 0.01). Although there was no difference in the level of physical activity between police officers from different shifts, declines in physical activity were associated with higher values of BMI.

Background: Physical inactivity is a serious public health problem for people of all ages and is currently the fourth highest global risk factor for mortality. The transition period from adolescence to adulthood coincides with a marked reduction in participation in physical activity, with more than 50% (and up to 80%) of young adults stopping physical activity. This decrease in physical activity is more evident in women than in men. Despite efforts, existing programs face challenges in effectively initiating and maintaining physical activity among individuals, particularly women, for extended durations. To address these limitations, the Women’s Involvement in Steady Exercise (WISE) randomized controlled trial (RCT) seeks to assess the efficacy of a digital high-intensity training intervention complemented by nutritional plans and other health-related advice. Methods: The study will be a three-center, randomized (1:1), controlled, parallel-group trial with a six-month intervention period. A total of 300 participants will be recruited at three study sites in Spain, Serbia and Italy. The participants will be randomized to one of the two groups and will follow a six-month program. The primary outcome of the study is the daily step count. Self-reported physical activity, the adherence to the exercise program, body composition, physical activity enjoyment, quality of sleep and physical capacities will also be evaluated.

Basic sports management in preschools is an area on which, in the region of Southeast Europe, no country has particularly focused. Investing in preschool sports organization is necessary for several reasons: The first reason is to raise the level of the nation's health. The second reason relates to the prevention of illness in later life, and the third reason is the possibility of creating future athletes, or making a home base from which the most talented children would be directed to local clubs in sports in which they have shown interest in or talent for. It is essential for sports activities to be available to every child, and in order to achieve this, sports for children should be free of charge.

The aim of this paper is to present guidelines and perspective on observing objective circumstances and subjective factors which explain why European and Serbian two football clubs which have won most trophies, are where they are today. The sample of the analysis consists of six top European clubs and two of the most successful football clubs from Serbia. Football club ownership structures primarily depend on the government arrangement, i.e. the legislative norms of the state in which they exist. Football clubs in Serbia function as civic organizations. A comparative analysis of European and Serbian clubs has been conducted, by using the generally accepted Polonsky model of sports organizations. It is easily applicable to football as well, and it is about 12 factors that influence one sports, in this case, football organization. As in many spheres, Serbian best clubs are far behind European standards. Sports success in qualifications for the European competitions and sporadic participation are more the result of sports performances and team strength than their organization and structure. While European football is becoming one of the most important elements of the economy and the society, contributing to improvement and changing cities, regions or countries, Serbian football is primarily a burden and an expense for the economy and the society.

Objectives: This study aimed to examine the structure of anthropometric characteristics, motor skills and specific motor skills in young football players. Methods: Study participants (427 male football players) were divided into pre-pioneers (11–13 y), n = 133; pioneers (13–15 y), n = 160; and cadets (15–17 y), n = 134. The entire sample of subjects was evaluated using 13 anthropometric and seven motor variables. The factor structure for each chronological age group was determined using Hotelling’s method. Results: Anthropometric characteristics showed three extracted factors in the pre-pioneers group, four factors in the pioneer group and two factors in the cadet group. Motor skills displayed three factors for the youngest group, two factors for the pioneers and three factors for the cadet group. Four factors were determined for specific motor skills in pre-pioneers, four in pioneers and three in cadet age. Conclusions: This study revealed structural variability and non-uniformity in the latent dimensions across age groups, with the total number of factors fluctuating between two and four. This study revealed two consistent latent dimensions in anthropometric data across all age groups: general morphological parameters and subcutaneous fat tissue. In motor skills, an initial universal factor is separated into central and energetic regulation of movements. Finally, specific motor skills demonstrated a transition from a highly differentiated four-factor structure in younger players toward a more integrated functional system in the oldest cohort, comprising intermuscular coordination, running speed with and without a ball; segmental speed of the lower extremities with a ball; and explosive force in hitting a ball with the foot and head.
