Digital twins in sport : concepts, taxonomies, challenges and practical potentials
Tilen Hliš, Iztok Fister, Iztok Fister, 2024, pregledni znanstveni članek

Opis: Digital twins belong to ten of the strategic technology trends according to the Gartner list from 2019, and have encountered a big expansion, especially with the introduction of Industry 4.0. Sport, on the other hand, has become a constant companion of the modern human suffering a lack of a healthy way of life. The application of digital twins in sport has brought dramatic changes not only in the domain of sport training, but also in managing athletes during competitions, searching for strategical solutions before and tactical solutions during the games by coaches. In this paper, the domain of digital twins in sport is reviewed based on papers which have emerged in this area. At first, the concept of a digital twin is discussed in general. Then, taxonomies of digital twins are appointed. According to these taxonomies, the collection of relevant papers is analyzed, and some real examples of digital twins are exposed. The review finishes with a discussion about how the digital twins affect changes in the modern sport disciplines, and what challenges and opportunities await the digital twins in the future.

Digital twin in sport: from an idea to realization
Luka Lukač, Iztok Fister, Iztok Fister, 2022, izvirni znanstveni članek

Opis: A digital twin is a virtual model to reflect a physical object and helps it by making proper decisions. The decision-making process is based on the same input data that the simulated physical object has access to. Due to exploiting artificial intelligence, the decision-making process of the digital twin is more sophisticated than that of the physical object. In this study, the digital twin is applied to the sports training domain, where it addresses those questions that have arisen during the implementation of interval cycling training sessions. Thus, the digital twin runs on a mobile device (i.e., the Raspberry Pi platform), with which a cycle is equipped and demonstrates user-friendliness, robustness, reliability, and accuracy. The interval training sessions are transferred to the mobile device in the form of the domain-specific language EasyTrain, ensuring higher expressive power and ease of use. During the implementation, the digital twin advises the athlete with predicted information obtained by a sophisticated prediction model via a screen. The results of a huge experimental work showed that the difference in the average efficiency of the interval training implementation between the two cyclists that performed the experiments is prominent, as the efficiency of the professional training surpassed 90%, while the amateur training efficiency barely achieved 70%.

Effects of high-load and low-load resistance training in patients with coronary artery disease : rationale and design of a randomised controlled clinical trial
Tim Kambič, Nejc Šarabon, Vedran Hadžić, Mitja Lainščak, 2021, izvirni znanstveni članek

Opis: Introduction: Resistance training (RT) combined with aerobic training (AT) enhances the effects of cardiac rehabilitation (CR) in patients with coronary artery disease (CAD). However, it remains to be investigated which type of RT (high loads (HLs) vs low loads (LLs)) is more efficacious in improving exercise performance, cardio-metabolic health and quality of life. Methods and analysis: A randomised, controlled, clinical trial will enrol 20 patients with CAD into each of three study arms (total 60 patients): HL-RT (70%–80% of one repetition maximum (1-RM)) combined with AT; LL-RT (30%–40% of 1-RM) combined with AT and AT alone as standard care. Primary outcomes (maximal aerobic capacity, maximal leg isometric strength) will be assessed at baseline and after 36 training sessions. Other outcomes will include acute haemodynamic responses to LL-RT and HL-RT, body composition, physical performance, blood biomarkers (lipids, glucose metabolism, inflammation, growth factors), physical activity and quality of life. The intention-to-treat principle will be used to analyse the data. Ethics and dissemination: The study design and protocol have been approved by the National Medical Ethics Committee of Slovenia (registration number: 0120-573/2019/15). The study will be conducted in accordance with the Declaration of Helsinki. The results of the study will be published as peer-reviewed manuscripts and congress presentations, communicated with patients and the clinical community, and shared through posts on social media. The findings of the study will be disseminated among the national CR clinical community (CR centres, Slovenian association of coronary clubs) with active participation of the patients enrolled in the study. This study will expand our knowledge of RT in combination with AT in CR. We expect to find different effects of HL-RT versus LL-RT, with implications for RT strategies in rehabilitation of patients with CAD.

Associations between physical activity and academic competence : a cross-sectional study among Slovenian primary school students
Joca Zurc, Jurij Planinšec, 2022, izvirni znanstveni članek

Opis: Physical activity has beneficial effects on overall academic performance in children. However, there is a lack of evidence regarding how the individual characteristics of physical activity interact with other confounding variables of academic competence. Leisure-time physical activity with potential confounders—such as developmental, behavioral, family, and school factors, predicting overall, mathematical, and reading academic competence—was studied in a random sample of 1520 Slovenian primary school students in grades 4–6 (51.9% female; mean age = 10.4 years; SD = 0.93). A structured self-reported questionnaire was used to gather data on the children’s leisuretime physical activity and social-demographic variables, while academic competence was measured by teachers using the SSRS Academic Competence Evaluation Scale. The findings showed that children engage in physical activity most days a week, with moderate-intensity and unorganized activities. It was predicted that engaging in physical activity would lead to an increase in academic performance by 4.2% in males (p = 0.002) and 3.2% in females (p = 0.024), but after fully adjusting the model for controlling confounding variables, the prediction increased to 81.1% in females and 84.1% in males (p < 0.001). The frequency and intensity of physical activity, the absence of digital games, and attending sports clubs seem to have the most beneficial effects in terms of academic competence in school children, among other relevant confounders mediating in this complex relationship.

European projects as a good practice of providing more opportunities for people with disabilities in sports tourism
Katja Čanžar, 2022, samostojni znanstveni sestavek ali poglavje v monografski publikaciji

Opis: Due to its important effects on individuals and society as a whole, sport is a fundamental right. Sports activities are not evenly distributed across all social categories. As disabled sports participants comprise a small share of the total, and as most public funding for sports in Slovenia falls on the shoulders of local communities, municipalities are forced to develop programs for these groups. Sports tourism is characterized by rapid and dynamic development. As an opportunity for municipalities we describe below an example of good practice in ensuring the accessibility of sports and recreation for people with disabilities in local communities through European projects. We also found that possibilities for people with disabilities in sports tourism are an increasingly important issue and that the field is developing. European and national policies dictate universal accessibility, which, however, is linked to the cost of architectural remodelling

Rural olympiads as promoters of old folk sports and games
Nevena Ćurčić, Željko Bjeljac, Jovana Brankov, 2022, samostojni znanstveni sestavek ali poglavje v monografski publikaciji

Opis: Traditional sports and games represent the folk tradition and culture of certain regions, part of the people’s intangible cultural heritage. Numerous traditional sports and games have been preserved in ex-Yugoslav republics, which are most often affirmed through village Olympiads and competitions in order to keep them from being forgotten. The aim of the study is to determine the content and program of rural Olympiads in ex-Yugoslav republics, the extent to which traditional sports and games are present, and the extent to which some modern sports are included. Also, the study focused on the impact of rural Olympiads on local communities and on the interaction between hosts and guests. The methodology used in the paper refers to field research (interview, observation), and document analysis, as well as the use of different data sources to validate and crosscheck findings. The results of the research indicate the presence of a large number of games of different character in the countries formed in Yugoslavia, as well as a large number of the same or similar games that arose more as a result of certain geographical and social conditions, and less as a feature of individual peoples.

Opis: Under the title Tourism and Development 2017 – Active and Sports Tourism: Feel the Freedom of Water we have conducted the 4th annual scientific conference, organized by the three partner faculties, Faculty of Tourism of the University of Maribor, Faculty of Sports and Tourism, Educons University from Novi Sad and Libertas Business school from Zagreb. This book of extended abstracts presents a wide range of over 25 different views on three topics that were discussed at the conference. The introductory part presents short summaries of thoughts discussed by our invited keynote speakers. The first section presents extended abstracts from the field of active tourism, which address the diverse aspects of active vacationing as becoming increasingly important in tourism. The second thematic section includes extended abstracts on the topic of sports tourism, a specific category of tourism that has been developing rapidly with more and more visitors coming to major international sports events and also more and more visitors actively seeking sports related vacation. The last section presents extended abstracts on accessible tourism, nowadays increasingly important area arising from the principles of ensuring equal opportunities and promoting social inclusion in tourism. All the extended abstracts provide scientific views on selected topics, and, thus, bring additional knowledge into the particular field of tourism.

Involvement in sports clubs and informal sport activities of primary and secondary school children in Liechtenstein
Jürgen Kühnis, Beat Wachter, Christian Frommelt, 2016, izvirni znanstveni članek

Opis: Sport involvement among children and adolescents has been a central field of research in sport science since years. This paper documents the participation of 11- to 15-year-olds in sport clubs and informal sport activities in Liechtenstein and examines possible gender- and age-specific differences. The analysis is based on four cross-sectional studies from 2004 to 2015 and includes the data of 1262 children in primary (5th grade) and secondary (7th and 9th grades) school. According to our findings sports and exercise are considered to be one of the main leisure-time activities for all school levels (irrespective of gender). The percentage of fully sport-abstinent adolescents by 11- and 13-year-olds is about 5 %; by 15-year-olds is around 10 %. The culmination of sports club membership (with current 84.7 %) appears to be at the age of 11 (5th grade). After the switch to secondary school the sports club commitment tends to decrease, while the high attendance of the informal sport activities (>85 %) shows relatively stable age development. In contrast to other child and youth studies, our data indicates a levelling tendency and dissolution of classic gender differences not only in sports club commitment but also in informal sports among girls and boys.
