Issues related to knowledge of nutrition and dietary supplementation (DS) are understudied in professional athletes. This study aimed to examine the possible association between knowledge of nutrition and DS (KN&DS) and dietary supplement use (DSU) among professional athletes involved in team sports. The sample comprised professional team-sport athletes (N = 912, age: 22.11 ± 3.37 years, 356 females) involved in four Olympic sports: basketball (N = 228), soccer (N = 324), volleyball (N = 154), and handball (N = 206). The participants were tested by previously validated questionnaires to examine their self-perceived competence on nutrition and DS (S/KN&DS), their objectively evaluated (tested) KN&DS (O/KN&DS), sociodemographic and sport-specific variables (predictors), and DSU (criterion). Associations between the predictors and the criterion (No-DSU - Irregular-DSU - Regular-DSU) were determined by multinomial regression analysis for the total sample and separately for the studied sports. DSU was found to be less prevalent in older and more successful players. The O/KN&DS and S/KN&DS were positively correlated with DSU, but S/KN&DS was a stronger predictor of DSU than O/KN&DS. Sport-specific associations between predictors and criterion were identified, with stronger correlations in sports with a higher prevalence of DSU. Due to the low correlations between O/KN&DS and S/KN&DS in the studied players, this study highlights the necessity for more frequent monitoring of biomarkers of nutritional status and its usage by coaches and practitioners to provide quantitative instruction.

Adolescence is considered to be the most important period for the prevention of substance use and misuse (SUM). The aim of this study was to investigate the problem of SUM and to establish potentially important factors associated with SUM in Kosovar adolescents. Multi-stage simple random sampling was used to select participants. At the end of their high school education, 980 adolescents (623 females) ages 17 to 19 years old were enrolled in the study. The prevalence of smoking, alcohol consumption (measured by Alcohol Use Disorder Identification Test–AUDIT), and illegal drug use (dependent variables), as well as socio-demographic, scholastic, familial, and sports-related factors (independent variables), were assessed. Boys smoke cigarettes more often than girls with daily-smoking prevalence of 16% among boys and 9% among girls (OR = 1.85, 95% = CI 1.25–2.75). The prevalence of harmful drinking (i.e., AUDIT scores of >10) is found to be alarming (41% and 37% for boys and girls, respectively; OR = 1.13, 95% CI = 0.87–1.48), while 17% of boys and 9% of girls used illegal drugs (OR = 2.01, 95% CI = 1.35–2.95). The behavioral grade (observed as: excellent–average-poor) is the factor that was most significantly correlated with SUM both in boys and girls, with lower behavioral grades among those adolescents who consume substances. In girls, lower maternal education levels were associated with a decreased likelihood of SUM, whereas sports achievement was negatively associated with risky drinking. In boys, sports achievement decreased the likelihood of daily smoking. Information on the factors associated with SUM should be disseminated among sports and school authorities.

Sport in the country is supported through program policies and is also supported in its development even with the difficulties that our society and the sports activity of the country has gone through. The management of sports clubs, federations and sports organizations in general develop their activities facing difficulties of a material nature when it comes to participation in international competitions. Therefore, this paper presents the management of money in sports organizations, infrastructure and other stakeholders. This paper is presented as a model, which has to do with the management, sports, infrastructural capacities that are at the moment, then also the distribution of the budget for federations, clubs, sports infrastructure and other organizations that perform these activities. The management of money for sports in the country has been executed for about 35 sports federations with about 867 sports clubs, where in total approximately 81.041 participate in sports activities, of which 67.583 are men and 13,458 women, and their amount spent was about 14,247,919 euro from the revenues of 18.489.005 euro that were from the country’s government. The management of money for sports in the country would open the way if appropriate measures are taken to increase the budget by engaging serious investors in terms of sports infrastructure in public- private partnerships, where this would then affect the addition of sports facilities and their management as rationally as possible where sports activities would then be increased and then this would also bring incomes. Meanwhile, sports organizations should be further supported in the operationalization of fiscal facilities for companies that are helping clubs and federations that wish to enter sports sponsorship, where this would also be pushing force in the development and improvement of sports and its conditions for the progress of sports activities.

Stages of growth and development in children are affected by various internal and external factors, some of which have a greater impact than others. Among internal factors, the most important one is the genetic factor which includes disposition, gender, race, etc. However, during phases of growth and development in children, it is important to know what is the body condition of the child as a system, and the functionality of each subsystem. That is because the functioning of each internal subsystem depends to a certain degree on the impact of external factors such as living conditions, body activity, season, hygiene and nutrition. The goal of this research was to verify the presence of any statistically significant differences in anthropometric body characteristics of Montenegro and Kosovo primary school students, in relation to their age. The respondents' sample was comprised of 600 primary school male students from Montenegro and Kosovo aged 13, 14 and 15 years old. The total sample of 600 respondents included 300 boys from Montenegro, and 300 boys from Kosovo. Anthropometric characteristics were assessed with a test battery of 12 anthropometric variables. Following a T-test for independent sample analysis, the acquired results show that there is a statistically significant difference in the manifesting area of anthropometric characteristics between 13, 14 and 15-year-old Montenegrin and Kosovar boys. Due to these reasons, the morphologic body structure, which is based on the mutual interactions of all anthropologic measures, could differ in various stages of development. More specifically, certain anthropometric characteristics in various time points can partake in a certain morphological body structure with various participation coefficients. However, the development of certain anthropometric characteristics is significantly determined by the individual frame of endogenous and exogenous conditioned factors, which in the same development period determine a different physiological age to various subjects. In some anthropometric characteristics, especially those significantly influenced by exogenous factors, variations in the population of the same chronological age may differ greatly. We may conclude that anthropometric characteristics vary in time depending not only on endogenic factors, but also ethnic, socio-economic, and other exogenous factors.
