The crumbling touchstone of the Vatican's ostpolitik : relations between the Holy see and Yugoslavia, 1970-1989
Jure Ramšak, 2021

Povzetek: Based on Yugoslav archival sources, the paper analyses the relationship between the Holy See and Yugoslavia as the only Eastern European socialist state with which the former had official diplomatic relations. The relationship between the Holy See and socialist Yugoslavia provides insight into the precarious position of the Catholic Church in Yugoslavia, but also into the issues and dilemmas that the Holy See faced in terms of its Ostpolitik towards Eastern European socialist regimes. The article initially centres on the parallels between the Holy See and the foreign policy agenda of non-aligned Yugoslavia, especially during the papacy of Paul VI, when both actors shared an understanding of the acute problems of the Global South. It then analyses the stance of the Holy See towards the Yugoslav domestic policy of self-management that claimed that this system could present a viable environment for the life of believers in modern socialist society. The analysis closes with an in-depth examination of the role of the Holy See in the process of convergence between religion and nationalism during the 1980s, in which the Vatican did not play as clear-cut a role as it has generally been ascribed and proved unable to tackle this formidable phenomenon.

A randomized crossover trial on the acute cardiovascular demands during flywheel exercise
Damir Zubac, Vladimir Ivančev, Zoran Valić, Rado Pišot, Cécil J. W. Meulenberg, Irhad Trozic, Nandu Goswami, Boštjan Šimunič, 2021

Povzetek: In a randomized crossover trial, we examined whether age plays a role in the mean arterial pressure (MAP) response during a vigorous flywheel exercise of varying load. We hypothesized that the magnitude of increase in the MAP during the flywheel exercise would increase in proportion to advancing age, thereby imposing a significant challenge to the cardiovascular system. A total of 30 participants of both sexes (age range from 20%55 y, 37% women) underwent a detailed medical examination, and their maximal oxygen uptake was determined. They performed a squat exercise (2 sets % 7 repetitions) on a flywheel ergometer at three randomly assigned moments of inertia set at 0.025, 0.05, and 0.075 kg m2, while the cardiovascular response was continuously recorded via a Task force monitor. Compared to the resting values, robust rises in the MAP were observed during all three flywheel loads, reaching the highest value of 179 % 4 mmHg (p = 0.001) during the highest load. In parallel, the cardiac index (cardiac output normalized by the body surface area) was two-fold greater during all the flywheel loads compared to rest, and at a high load, exclusively, the total peripheral resistance increased by 11% (p = 0.001). The rise in heart rate compensated for a load-dependent drop in the stroke index (stroke volume normalized by the body surface area). In our study population, no correlations were observed between the relative increase in the MAP and the participants% age for the three flywheel loads. The present findings suggest that the larger moments of inertia impose a substantial burden to the cardiovascular system, without apparent associated age-differences of the relative magnitude of MAP rise throughout the exercise.

Ecodemocracy in practice : exploration of debates on limits and possibilities of addressing environmental challenges within democratic systems
Helen Kopnina, Reingard Spannring, Shé Mackenzie Hawke, Colin D. Robertson, Alessio Thomasberger, Michelle Maloney, Marco Morini, William Lynn, Naziru Zakari Muhammad, Francisco J. Santiago-Ávila, Hana Begovic, Mariusz Baranowski, 2021

Povzetek: This article examines the practical implications of ecological democracy or ecodemocracy, inquiring how capable democratic societies are of addressing environmental challenges. It asks: What is needed to secure democratic legitimacy for policy measures to benefit nonhuman species? What would ecodemocracy look like in practice? Different types of existing and possible types of representation are discussed, including the expansion of the precautionary principle, the Council of All Beings or Parliament of Things, and representation through the Parties for Animals. A possible approach in the form of a mandate for proxy ecorepresentation similar to civil rights through continuous affirmative action is investigated. Limitations and possibilities of each approach for nature representation are weighed.

Neuromuscular junction instability and altered intracellular calcium handling as early determinants of force loss during unloading in humans
Elena Monti, Carlo Reggiani, Martino V. Franchi, Luana Toniolo, Marco Sandri, Andrea Armani, Sandra Zampieri, Boštjan Šimunič, Rado Pišot, Marco Vincenzo Narici, 2021

Povzetek: Unloading induces rapid skeletal muscle atrophy and functional decline. Importantly, force is lost at a much higher rate than muscle mass. We aimed to investigate the early determinants of the disproportionate loss of force compared to that of muscle mass in response to unloading. Ten young participants underwent 10 days of bed rest (BR). At baseline (BR0) and at 10 days (BR10), quadriceps femoris (QF) volume (VOL) and isometric maximum voluntary contraction (MVC) were assessed. At BR0 and BR10 blood samples and biopsies of vastus lateralis (VL) muscle were collected. Neuromuscular junction (NMJ) stability and myofibre innervation status were assessed, together with single fibre mechanical properties and sarcoplasmic reticulum (SR) calcium handling. From BR0 to BR10, QFVOL and MVC decreased by 5.2% (P = 0.003) and 14.3% (P < 0.001), respectively. Initial and partial denervation was detected from increased neural cell adhesion molecule (NCAM)-positive myofibres at BR10 compared with BR0 (+3.4%, P = 0.016). NMJ instability was further inferred from increased C-terminal agrin fragment concentration in serum (+19.2% at BR10, P = 0.031). Fast fibre cross-sectional area (CSA) showed a trend to decrease by 15% (P = 0.055) at BR10, while single fibre maximal tension (force/CSA) was unchanged. However, at BR10 SR Ca2+ release in response to caffeine decreased by 35.1% (P < 0.002) and 30.2% (P < 0.001) in fast and slow fibres, respectively, pointing to an impaired excitation%contraction coupling. These findings support the view that the early onset of NMJ instability and impairment in SR function are eligible mechanisms contributing to the greater decline in muscle force than in muscle size during unloading.

Independent infuence of age on heart rate recovery after flywheel exercise in trained men and women
Damir Zubac, Nandu Goswami, Vladimir Ivančev, Zoran Valić, Boštjan Šimunič, 2021

Povzetek: The present study examined whether differences in the heart rate recovery following flywheel exercise cessation were associated with differences in maximal oxygen uptake (V%O2 max.), age and sex in trained adults. Eleven men (age range 22%49 years, V%O2 max.%=%43.6%%%7.6 mL kg min%1) and ten women (age range 20%53 years, V%O2 max.%=%38.0%%%5.7 mL kg min%1) were randomly assigned to complete a squat-exercise on the flywheel ergometer set at three different moments of inertia, while their cardiovascular responses were continuously monitored. During the flywheel exercise the mean arterial pressure rose by%~%35 to 40% (p%=%.001), and the increment was more robust in men than women. The cardiac index was two-fold greater across both sexes compared to the baseline (p%=%.001), while the rise in heart rate (~%144 bpm) was more pronounced in women to compensate for their load-dependent stroke index decline (p%=%.001). The load-independent time-course changes in heart rate recovery markers were comparable between the sexes. When these indicators were pooled, a stepwise regression revealed age as the only relevant predictor of both fast and slow components of the heart rate recovery (~%30% of the shared variance explained, p%=%.014). The present data suggest that the heart rate recovery declines with age, irrespective of sex, or well-preserved cardiorespiratory fitness in moderately-trained adults.

Effect of a warm-up protocol with and without facemask-use against COVID-19 on cognitive function : ǂa ǂpilot, randomized counterbalanced, cross-sectional study
Maamer Slimani, Bianca Miarka, Hela Znazen, Wassim Moalla, Amri Hammami, Armin Paravlić, Nicola Luigi Bragazzi, 2021

Povzetek: The present study aimed to verify the effect of a warm-up protocol with and without facemask-use on cognitive function. The sample was composed of 17 healthy, non-smoking physical education students (age = 17.6 years, height = 1.71 m, and body mass = 69.7 kg). They were randomized to perform 15 min of warm-up exercises, while wearing a cloth facemask (EXP) or no mask (CON) on two separate occasions, with at least 48-h separating conditions. Rate of perceived exertion (RPE) and d2 Attention assessment were used to verify cognitive function, using a repeated measures general linear model. The warm-up improved cognitive abilities and the results demonstrated significant differences between the EXP vs. CON groups in post-concentration performance (186.06 % 15.47 EXP-score vs. 178.12 % 13.66 CON-score), post the total number of errors (23.47 % 14.50 EXP-frequency < 29.06 % 13.74 CON-frequency), and in the post RPE (6.0 % 1.37 EXP-index > 4.7 % 0.85 CON-index). Wearing a cloth facemask caused positive effects on cognitive function. This data suggests that wearing a cloth facemask during warm-up may stimulate/improve the cognitive function.

Učinkovitost računalniškega kognitivnega treninga v domovih starejših občanov
Uroš Marušič, Zdenka Milič Žepič, Voyko Kavcic, 2021

Povzetek: Ohranjanje in krepitev fi zičnega in kognitivnega zdravja je pri starejših osebah izziv, še posebej pri tistih, ki so podvržene pospešenim starostnim ali nevrodegenerativnim spremembam. Obstoječe nefarmakološke intervencije lahko stabilizirajo ali upočasnijo kognitivni upad, vendar se učinkovite preventivne tretmaje, ki bi zakasnili pojavnost simptomov, še raziskuje. Eden izmed nefarmakoloških tretmajev je kognitivni trening. Namen naše raziskave je bil oceniti izvedljivost in učinkovitost kognitivnega treninga z nalogo prostorske navigacije pri stanovalcih domov starejših občanov. Enaintrideset stanovalcev (povprečna starost 81,6 leta, razpon 69%94 let; povprečna ocena MoCA 22,8 točke, razpon 17%27; 7 moških) je bilo naključno razporejenih v kontrolno skupino ali intervencijsko skupino. Slednja je bila vključena v dvomesečni kognitivni trening (2-krat tedensko; skupaj 16 treningov), v katerem so udeleženci vadili učenje virtualnega labirinta. Vsi udeleženci raziskave so bili merjeni pred in po intervenciji na nevropsihološki ocenjevalni bateriji testov. Udeleženci kontrolne skupine niso prejeli nobene posebne obravnave in so tako sodelovali le na %pred in po% meritvah. Pomembne izboljšave so bile ugotovljene le pri Reyjevem testu slušno-besednega učenja (AVLT), kjer so udeleženci v intervencijski skupini značilno izboljšali svoj rezultat v primerjavi s kontrolno skupino. Kljub omejeni učinkovitosti kognitivnega treninga je bila naša intervencija izvedljiva in pozitivno sprejeta s strani večine udeležencev. Nadaljnje raziskave bi morale ovrednotiti dolgoročne učinke kognitivnega treninga na druge funkcionalne sposobnosti in aktivnosti vsakodnevnega življenja. Na splošno naša raziskava ponuja empirične dokaze, da je kognitivni trening sprejemljiv za stanovalce domov za starejše občane, in kar je najpomembneje, da lahko izboljša mnemonične kognitivne sposobnosti.

Higher neural demands on stimulus processing after prolonged hospitalization can be mitigated by a cognitively stimulating environment
Uroš Marušič, Rado Pišot, Voyko Kavcic, 2021

Povzetek: Prolonge d periods of complete physical inactivity or bed rest trigger various alterations in the functional and metabolic levels of the human body. However, bed rest-related adaptations of the central nervous system are less known and thoroughly studied. The aim of this study was to investigate brain electrophysiological changes using event-related potentials (ERPs) after 14 days of bed rest and 12 consecutive sessions of computerized cognitive training (CCT). Sixteen older (Mage= 60 years) healthy volunteers were randomly divided into a CCT treatment group and an active control group. All participants performed ERP measurements based on the foveal visual presentation of a circle on a black background before and after bed rest. After 14 days of bed rest, participants in the control group showed increased peak P1 amplitude (p = .012), decreased P1 latency (p = .024), and increased P2 amplitude (p = .036), while the CCT group also showed decreased P1 latency (p = .023) and decreased P2 latency (p = .049). Our results suggest that, even from a central adaptation perspective, prolonged periods of physical inactivity or bed rest trigger additional neural recruitment and should therefore be minimized, and that CCT may serve as a tool to mitigate this. Future research should focus on other aspects of central nervous system adaptation following periods of immobilization/hospitalization to improve our knowledge of infl uence of physical inactivity and its eff ects on cortical activity and to develop appropriate countermeasures to mitigate functional dysregulation.

Children's daily routine response to COVID-19 emergency measures in Serbia
Saša Pišot, Dragan Krivokapić, Nebojša Maksimović, Ivana Milovanović, Radenko Matić, Jovan Vuković, 2021

Povzetek: Objective: The emergence of coronavirus in Serbia as well as in other European countries led to the declaration of a state of emergency, which, among other measures, included a switch to online education, the lockdown of public life and organized sports, and a curfew from 5 pm to 5 am. This study aimed to investigate the extent to which these measures affected children%s daily routines. More specifically, it aimed to determine how children maintained their learning, physical activity, and screen time routines from the period before the state of emergency was declared. Methods: Response to an online parent-reported questionnaire was conducted (N = 450). The factorial validity of the scales was prepared using confirmatory factor analysis, with acceptable fit indices. Based on that, the authors tested the interrelations between dimensions using structural equation modeling in SPSS, AMOS 24.0. Results: The study results indicate a positive relationship between school achievement and study time (% = 0.25). They also indicate that children who were physically active before the pandemic continued their activities during the emergency state (% = 0.53). Physical activity impact during the COVID-19 emergency measures reduces children%s behavior changes (% = 0.55). Finally, they highlight that children who spent more time with multimedia content had greater changes in anxiety, sensitivity, nervousness, and worry due to COVID-19 emergency measures (% = %0.38). Conclusions: Healthy lifestyle habits formed in childhood are suggested to be responsible for the greater %resistance to change% shown by the children from this study.
