241. Tensiomyography : from muscle assessment to talent identification toolDražen Čular, Matej Babić, Damir Zubac, Ana Kezić, Iva Macan, Leonardo Alexandre Peyré-Tartaruga, Francesco Ceccarini, Johnny Padulo, 2023, review article Abstract: Introduction: Tensiomyography (TMG) is a non-invasive and cost-effective tool that is gaining popularity in fields such as sports science, physical therapy, and medicine. In this narrative review, we examine the different applications of TMG and its strengths and limitations, including its use as a tool for sport talent identification and development. Methods: In the course of crafting this narrative review, an exhaustive literature search was carried out. Our exploration spanned several renowned scientific databases, such as PubMed, Scopus, Web of Science, and ResearchGate. The materials we sourced for our review included a broad spectrum of both experimental and non-experimental articles, all focusing on TMG. The experimental articles featured varied research designs including randomized controlled trials, quasi-experiments, as well as pre-post studies. As for the non-experimental articles, they encompassed a mix of case-control, cross-sectional, and cohort studies. Importantly, all articles included in our review were written in English and had been published in peer-reviewed journals. The assortment of studies considered provided a holistic view of the existing body of knowledge on TMG, and formed the basis of our comprehensive narrative review. Results: A total of 34 studies were included in the review, organized into three sections: 1) assessing muscle contractile properties of young athletes, 2) using TMG in the talent identification and development process and 3) Future research and perspectives. According to data presented here, the most consistent TMG parameters for determining muscle contractile properties are radial muscle belly displacement, contraction time, and delay time. Biopsy findings from the vastus lateralis (VL) confirmed TMG as a valid tool for estimating the ratio of myosin heavy chain (%MHC-I). Conclusion: TMGs ability to estimate the ratio of %MHC-I has the potential to aid in the selection of athletes with the muscle characteristics best suited for a particular sport, eliminating the need for more invasive procedures. However, more research is warranted to fully understand TMG’s potential and its reliability when used with young athletes. Importantly, the use of TMG technology in this process can positively impact health status, reducing the frequency and severity of injuries and the duration of recovery, and subsequently can reduce drop out rates among youth athletes. Future studies should look at twin youth athletes, as a model capable of discriminating between the influence of hereditary factors vs. environmental factors, in therms of muscle contractility and TMG’s potential for instance.

244. Validation of the Slovenian version of the Movement imagery questionnaire for children (MIQ-C) : a measurement tool to assess the imagery ability of motor tasks in childrenLuka Šlosar, Katarina Puš, Uroš Marušič, 2023, original scientific article Abstract: Purpose: The ability to perform motor imagery has been shown to influence individual athletic performance and rehabilitation. Recent evidence supports its potential as a training tool to improve motor skills in children. Although there is a standardized assessment of the imagery abilities in Slovenian-speaking adults, there is currently no validated instrument for use with Slovenian children. Therefore, the aim of the present study was to conduct a linguistic validation study of the movement imagery questionnaire for children (MIQ-C). Methods: A total of 100 healthy children (mean age 10.3±1.3 years; 50 female) were assessed with a Slovenian version of the MIQ-C at Day 1 and Day 8. Inter-day agreement was examined using intraclass correlation coefficients (ICC). Construct validity and internal consistency were assessed using a Cronbach’s alpha coefficient and exploratory – confirmatory factor analysis, respectively. Results: The test-retest ICC were very high for all three scales examined (ICCKI=0.90; ICCIVI=0.92; ICCEVI=0.90). Excellent internal consistency (up to 0.90) was found for kinaesthetic and both visual imageries. Confirmatory analysis confirmed a three-factorial structure of the MIQ-C. Conclusions: The Slovenian version of the MIQ-C proved to be highly reliable and valid in assessing children’s motor imagery abilities, and as such for use with Slovene-speaking children. Moreover, this standardized instrument can be a helpful tool in training and rehabilitation practice with children aged 7-12 years.

245. Twinning across the Adriatic : history, memory and municipal co-operation between Italy and Yugoslavia during the Cold WarBorut Klabjan, 2023, original scientific article Abstract: The heritage of World War II left an indelible mark on the relations between Italy and Yugoslavia. During the détente period, however, these two countries were able to overcome many historical resentments and established a fruitful co-operation in Cold War Europe. This article questions the engagement on state, regional and municipal levels and analyses the role of twin cities in this multilayered process. With the help of primary sources, we learn how the heritage of World War II played an important role in building new forms of post-war co-operation. In fact, post-war twinning is often the result of shared anti-fascist activities from the war years. However, this is not confined to communist municipalities or ‘red’ regions in Italy on one side, and socialist Yugoslavia on the other, but is a more fluid and flexible practice which involves historical ties, geographical positions, personal capacities and economic needs.

246. Pantheism from the perspective of Wittgensteinian nonoverlapping magisteria (WNOMA)Gorazd Andrejč, 2023, original scientific article Abstract: This essay examines pantheism within the framework of the ‘faith and reason’ field in the philosophy of religion, with an emphasis on the question of the relationship between pantheism and empirical–scientific rationality. I address this question from what I call the Wittgensteinian Nonoverlapping Magisteria (WNOMA) approach to religion and science. WNOMA affirms a categorial difference between religious and scientific language and attitudes. This difference is interpreted with the help of Wittgenstein’s distinction between religious and scientific beliefs and van Fraassen’s distinction between religious and empiricist stances. This means that WNOMA is antievidentialist regarding religious beliefs and sees the experiential and instinctive aspects of religion as more fundamental than the systematic–intellectual aspect. Part of the variety in contemporary pantheism relates to the question of whether the emphasis is on the experiential–spiritual side of pantheism or its intellectual side, i.e., whether pantheism is ‘hot’ or ‘cold’. I examine a few telling examples: Spinoza, Einstein, the World Pantheism Movement and a recent awe-some argument for pantheism by Ryan Byerly. The main contribution of this paper is a critical reading of these versions of pantheism from a WNOMA perspective, through which I hope to establish the plausibility and show some of the persuasive force of the WNOMA approach to pantheism, focusing on the relation of pantheism to scientific rationality on the one hand and felt experience on the other. I argue that hotter kinds of pantheism can be intellectually virtuous if they find a way to combine the empiricist stance and pantheist religious stance, even without a developed philosophical or theological system. I also argue that colder and philosophically rigorous pantheism can be problematic if it assumes religious evidentialism, neglects the experiential part of pantheism in favor of intellectualism or/and confuses the spheres of science and religion.

247. The optimal kinematic model of the performance of the clear hip circle to handstand on the uneven bars : a case studyEmilija Petković, Saša Veličković, Edvard Kolar, Ratko Stanković, Daniel Stanković, 2023, original scientific article Abstract: The aim of this research was to define the optimal kinematic parameters of performance of the Clear hip circle to handstand on uneven bars (KOVT). The optimal kinematic model defined in this case study represents an example of the successful performance of the Clear hip circle to handstand on the uneven bars. The exercise was performed at the 39th and 40th World Cup in Artistic gymnastics in Maribor (SLO). The kinematic parameters were specified by the APAS 3-D video system (Ariel Dynamics Inc., San Diego, CA), using 16 anthropometric reference points and 8 body segments (Foot, Ankle, Knee joint, Hip joint, Wrist, Elbow joint, Shoulder joint and Head), in which one of the points represents the center of gravity of the body. The female gymnasts (N=15), mean age 17.5 yrs, who performed one Clear hip circle on the uneven bars performed two KOVTs in their gymnastics routine, while the rest performed one KOVT on the uneven bars, mean age 17.5. The main method in this research was kinematic, and the additional one was statistical. Optimizing the technique of successful performance of the KOVT is important for detecting different styles of the technique that occur in female gymnasts.

248. Bootstrap percolation in strong products of graphsBoštjan Brešar, Jaka Hedžet, 2024, original scientific article Abstract: Given a graph $G$ and assuming that some vertices of $G$ are infected, the $r$-neighbor bootstrap percolation rule makes an uninfected vertex $v$ infected if $v$ has at least $r$ infected neighbors. The $r$-percolation number, $m(G,r)$, of $G$ is the minimum cardinality of a set of initially infected vertices in $G$ such that after continuously performing the $r$-neighbor bootstrap percolation rule each vertex of $G$ eventually becomes infected. In this paper, we consider percolation numbers of strong products of graphs. If $G$ is the strong product $G_1\boxtimes \cdots \boxtimes G_k$ of $k$ connected graphs, we prove that $m(G,r)=r$ as soon as $r\le 2^{k-1}$ and $|V(G)|\ge r$. As a dichotomy, we present a family of strong products of $k$ connected graphs with the $(2^{k-1}+1)$-percolation number arbitrarily large. We refine these results for strong products of graphs in which at least two factors have at least three vertices. In addition, when all factors $G_i$ have at least three vertices we prove that $m(G_1 \boxtimes \dots \boxtimes G_k,r)\leq 3^{k-1} -k$ for all $r\leq 2^k-1$, and we again get a dichotomy, since there exist families of strong products of $k$ graphs such that their $2^{k}$-percolation numbers are arbitrarily large. While $m(G\boxtimes H,3)=3$ if both $G$ and $H$ have at least three vertices, we also characterize the strong prisms $G\boxtimes K_2$ for which this equality holds. Some of the results naturally extend to infinite graphs, and we briefly consider percolation numbers of strong products of two-way infinite paths.
