Association football (soccer) is the most popular sport in the world, resulting in a large economic interest from investors, team managers, and betting agencies. For this reason, a vast number of rating systems exists to assess the strength of football teams or individual players. Nevertheless, most of the existing approaches incorporate deficiencies, e. g., that they depend on subjective ratings from experts. The objective of this work was the development of a new rating system for determining the playing strength of football players. The Elo algorithm, which has established itself as an objective and adaptive rating system in numerous individual sports, has been expanded in accordance with the requirements of team sports. Matches from 16 different European domestic leagues, the UEFA Champions and Europa Leagues have been recorded, with more than 17 000 matches played in recent years, and 12 400 different players. The developed rating system produced promising results, when evaluating the matches based on its predictions. A high relevance of the created system results from the fact that only the associated match report is needed and thus—in relation to existing valuation models—significantly more football players can be assessed.

For many people, the process of assessing one person to another is negative and can be defined as objectification, due to subjective perception and social attitudes. But in society, there is still a need to assess the attributes of the subject and therefore, in order to separate a bad assessment from a good one and not cause a public outcry, it is necessary to introduce a new term digitification, which carries a neutral connotation and does not violate people's personal boundaries. Such a term will make it possible to separate the concepts of objectification and digitification, not to confuse them and not to ascribe to each other inappropriate characteristics. Digitification is the process of assessing the attributes of a certain person on a voluntary basis by another person or artificial intelligence, based on objective criteria created for a particular rating system. Moreover, rating systems are different and have different functions, and therefore the rating system must be correctly selected in order to be more accurate and effective. Various online services and trading platforms have their own rating systems, their business is successful and relationships with customers are well established. Moreover, there is a whole state in the world in which the rating system is an integral part of society and it also shows good results. This article was created with the aim of introducing a new term digitification into everyday life that can change the course of human thinking for the better and open up new possibilities in the field of measurement systems through ratings and reviews.

The purpose of this research is to compare some coordinative abilities in terms of team and individual sports. A total of 112 athletes were included in the research, of which 60 athletes were from individual sports (Athletics=20, Archery=20, Karate=20) with mean age of 15.02±0.813 years, mean body height of 1.64±0.88 meters and mean body weight of 54.80±11.196 kilograms and 52 athletes were from team sports (Football Player=32, Basketball Player=20) with mean age of 14.98±0.727 years, mean body height of 1.67±0.90 meters and mean body weight of 58.10±9.770 kilograms. Numbered medicine ball run test, backward medicine ball throw test and sprint at the given rhythm test were used to evaluate performances related to coordinative abilities. When our results are examined, it is seen that averages of the participants in team sports category in terms of rhythm, orientation and differentiation abilities are at better level than averages of the participants in individual sports category. It has been seen that individuals in team sports category have significantly better performance than athletes in individual sports in terms of their orientation and differentiation abilities. On the other hand, no significant difference was found for rhythm ability. Consequently, results of the study confirm our pre-research expectations. On the other hand, when literature is examined, it is significant that results obtained from other studies examining coordinative abilities of the athletes in individual sports and team sports categories are similar to our results. It has been seen in the studies in the literature that some results are not similar. It can be thought that different results are caused by age differences and differences in types and branches of sports in which athletes participate.

Multiple sustainability standards and rating systems have been developed to draw attention to constructing sustainable buildings. The Pearl Rating System (PRS) is a mandate for all new construction projects in Abu Dhabi. Hence, it is important to understand the main components, advantages, and limitations of the PRS. The feasibility and the practical relevance of the PRS are still being studied. This paper addresses this gap and critically evaluates the PRS against some of the well-established rating systems like LEED and BREEAM. The analysis suggests that the PRS considers the cultural aspect of sustainability, in addition to the environmental, societal, and economic aspects. It was also found that most rating systems, including the PRS, have a very superficial inclusion of life cycle assessment (LCA). The paper finally concludes with other observations and outlook for a more robust implementation of the PRS.

The aim of this investigation was to identify possible related factors associated to the performance of the crunning test in European children and adolescents. A total number of 559 children and adolescents (age range 6–14 years) of which 308 boys (55.1%) and 251 girls (44.9%), from seven European countries, were screened. A questionnaire concerning demographic and personal life-related factors and a cognitive assessment were performed. A regression analysis was conducted with the performance measures of the crunning movement. T-tests and ANCOVA were used to analyze sub-group differences. Boys have greater crunning performance values compared to girls (5.55 s vs. 7.06 s, p < 0.001) and older children perform better than younger ones (R2 −0.23; p < 0.001). Children with healthy and active habits (exercising or spending time with family members vs. reading or surfing the internet) performed better in the test. Children engaged in team sports had better crunning performances compared to those engaged in individual sports (6.01 s vs. 6.66 s, p = 0.0166). No significant association was found regarding cognitive-related aspects in either children engaged in team or individual sports and the crunning performance. Older and male children performed better in the crunning test than younger and female children. Physical activity-related aspects of children’s life are associated with crunning movement performance. No association was found between higher cognitive performance and the crunning test results.

Спортивное питание в настоящее время - это неразделимый сплав, представляющий на практике реализацию современных достижений спортивной физиологии на основе использования специально разработанных продуктов питания со строго научно обоснованным составом. Цель работы заключалась в оценке распространенности в настоящее время продуктов спортивного питания среди различных групп спортсменов и широких слоев населения; в выявлении основных целей, которые ставят перед собой их потребители; в анализе динамики ассортимента продукции на рынке; в определении мотивирующих факторов, оказывающих влияние на потребление этих продуктов и прогнозирование направлений дальнейшего их развития. Доля спортсменов различного уровня, использующих продукты спортивного питания, в настоящее время в разных странах мира составляет от 48 до 81 %. В качестве основных целей их потребления рассматривается повышение уровня спортивных достижений, укрепление состояния здоровья, ускорение процесса восстановления после тренировок и соревнований, улучшение внешнего вида и снижение вероятности получения спортивных травм. Распространенность, объем потребления и ассортимент продуктов спортивного питания увеличиваются с ростом спортивной квалификации атлетов. По причине того, что индивидуальные спортивные дисциплины предъявляют более жесткие психологические требования к их участникам по сравнению с командными, распространенность спортивного питания среди спортсменов в индивидуальных видах спорта установлена выше, чем в командных. Данные проведенных исследований указывают на настоятельную необходимость, с целью обеспечения эффективности применения спортивного питания и предотвращения возникновения нежелательных побочных последствий, постоянного повышения квалификации спортсменов, тренеров, руководителей команд и сопровождающих их медицинских работников в области теории и практики применения современных продуктов спортивного питания. Sports nutrition nowadays is an indivisible alloy, representing in practice the implementation of modern achievements in sports physiology by using specially developted food products with a strictly scientifically formed composition. The purpose of this article was to assess the prevalence of sports nutrition products among various groups of athletes and general population; identifying the main goals that consumers set for themselves in this case; analyzing of the product dynamics on the market; establishing motivating factors that influence consumers behavior and forecasting directions of further sports nutrition development. The share of athletes of various levels using sports nutrition products in different countris of the world currently estimates from 48 to 81 %. The main goals of their consumption are comsidered to increase the level of athletics performance; improve health; accelerate the recovery process after training and competion; improve appearance and reduce the probability of sports injuries. The prevalence, consuption and variety of sports nutrition products used increase with the growth athletes` sports qualification. Due to the fact that individual sports disciplinces impose more stringent physological requirements on their participants compared to team sports, the prevalence of sports nutrition among athletes in individual sports is higher than in team sports. The data of studies indicate the urgent need, in order to ensure the proper effectiveness of the sports nutrition consumption and to avoid the occurance of undesirable side effects, of the carring out continuous knowledge upgrading of athletes, team leaders and accompaning medical personal in the field of theory and practice of sports nutrition.

Abstract Background: The purpose of the present study was to investigate how an athlete’s participation in either an individual or team sport is related to their attitude toward sport psychology consulting and their willingness to consult a sport psychology practitioner. Method: The Sport Psychology Attitudes-Revised form (SPA-R) was completed by one hundred and twenty athletes from individual and team sports. A 2 (Type of sport: individual and team) x 2 (Gender) multivariate analysis of variance (MANOVA) was conducted with attitudes towards sport psychology as dependent variables. In order to identify attitudes that accentuated the differences related to type of sport, follow-up univariate analyses were performed. Results: Results revealed that athletes involved in individual sports reported overall more positive attitudes towards sport psychology consulting than athletes involved in team sports. In particular, the athletes involved in individual sports were more likely to have greater confidence in sport psychology consulting. The findings also show that gender may mediate this association, indicated by a nearly significant two-way interaction effect for gender and type of sport (individual versus team) regarding confidence in sport psychology. The source of this marginal result was a larger effect of sport type for females than for males. Conclusions: The findings of this study imply that athletes involved in individual sports are more likely to have positive attitudes towards sport psychology compared to athletes competing in team-based sports. The results may go some way to assist sport psychologists to understand and address athletes’ concerns and to improve receptivity to sport psychology services.
