Effects of meditation on cardiovascular and muscular responses in patients during cardiac rehabilitation : a randomized pilot study
Maximilian E. Rudlof, Boštjan Šimunič, Bianca Steuber, Till O. Bartel, Ruslan Neshev, Petra Mächler, Andreas Dorr, Rainer Picha, Karin Schimd-Zalaudek, Nandu Goswami, 2022, izvirni znanstveni članek

Povzetek: Background: Cardiovascular diseases are the world’s number one cause of death, with exceeding psychosocial stress load being considered a major risk factor. A stress management technique that has repeatedly shown positive effects on the cardiovascular system is the Transcendental Meditation (TM) technique. The present pilot study aimed to investigate the potential effect of TM on the recovery of cardiac patients. Objectives: We hypothesized that practicing TM in patients undergoing a 4-week cardiac rehabilitation program augments the recovery of cardiovascular parameters and reduces skeletal muscle tone after rehabilitation. Methods: Twenty cardiac patients were recruited and randomly assigned to either the control or the TM group. Cardiovascular parameters were assessed with the Task Force Monitor (TFM) and skeletal muscle contractile properties by Tensiomyography during a sit-stand test, performed at the beginning and end of a 4-week in-patient rehabilitation program. Results: Systolic blood pressure (SBP) was significantly lower after 4 weeks of cardiac rehabilitation, while the RR-interval (RRI) significantly increased. At the skeletal muscle level, the contraction time and maximal displacement increased, though only in the gastrocnemius medialis and biceps femoris muscles and not in vastus lateralis. Group interactions were not observed for hemodynamic parameters nor for muscle contractile properties. Discussion: Although significant improvements in hemodynamic and muscular parameters were observed after 4 weeks of rehabilitation, we could not provide evidence that TM improved rehabilitation after 4 weeks. TM may unfold its effects on the cardiovascular system in the longer term. Hence, future studies should comprise a long-term follow-up.

Understanding interdisciplinarity through Adriatic maricultures and climate change adaptation : Elektronski vir
Cécil J. W. Meulenberg, Shé Mackenzie Hawke, Irina Moira Cavaion, Peter Kumer, Blaž Lenarčič, 2022, izvirni znanstveni članek

Povzetek: The consequences of accelerating climate change for land and sea biodiversity require innovative approaches to research. Interdisciplinary re-search serves to connect natural science, socialsciences and humanities, tech-nology, and engineering, as well as welcoming citizen scientists into the re-search environment. Interdisciplinarity is part of a developing innovative ap-proach to research that emphasizes co-evolution of traditional sciences, with citizen science and participatory engagement in the realisation of research goals and the promotion of climate change mitigation strategies. In this article, through the example of shellfish maricultures we illustrate interdisciplinarity, particularlydemonstrating how marine biology, health and well-being, social science and cultural geography come together at the interface between nature, culture, and climate change mitigation strategies.

Anthropocene challenges for youth research : understanding agency and change through complex, adaptive systems
Reingard Spannring, Shé Mackenzie Hawke, 2021, izvirni znanstveni članek

Povzetek: The Anthropocene has come to signify human dominance over the more-than-human world with all its negative consequences for this planet%s human and nonhuman inhabitants. As young people have started to express their feelings of concern and frustration with the inertia of the political elites, youth research, too, is called upon to reconsider and broaden its perspective. In particular, we argue, that the Anthropocene challenges anthropocentrism, dualisms, and traditional notions of agency in youth research, and must be critiqued through multi-disciplinary investigation. A transgression of the mainstream paradigm in youth research through the perspective of Complex Adaptive Systems Theory (CAS) could provide much needed analyses of a broad range of issues at the intersection of youth and ecological concerns. This article will therefore outline Complex Adaptive Systems Theory (CAS) as a multi-disciplinary tool, and apply it to two examples: the biosocial system of the Elwha River waterscape, and the #Fridays for Future strikes that are both motivated by environmental concerns. Finally, it discusses the possible contributions of a CAS approach in youth research to a better understanding of agency and change in ecologically turbulent times.

Dose-response relationship between endurance training prescription variables and increases in aerobic performance of healthy and unhealthy middle and very old individuals aged 70 years and older : a systematic review and meta-analysis of randomized controlled trials
Sarah Cheour, Chouaib Cheour, Nicola Luigi Bragazzi, Liye Zou, Armin Paravlić, Maamer Slimani, Foued Cheour, 2021, pregledni znanstveni članek

Povzetek: Background: The objectives of this systematic review and meta-analysis were to quantify the effectiveness of endurance training (ET) on aerobic performance (i.e., peak oxygen uptake (VO2peak)) in healthy and unhealthy middle and very old adults aged 70 years and older, and to provide dose response relationships of training prescription variables (in terms of frequency, and volume). Methods: Several scholarly databases (i.e., PubMed/MEDLINE, SpringerLink, ScienceDirect Journals, and Taylor & Francis Online Journals) were searched, identifying randomized controlled studies that investigated the effectiveness of ET on VO2peak in older adults. Standardized mean differences (SMD) were calculated. Results: In terms of changes differences between experimental and control group, ET produced significant large effects on VO2peak performance (SMD = 2.64 (95%CI 0.97%4.31)). The moderator analysis revealed that health status variable moderated ET effect onVO2peak performance. More specifically, ET produced larger SMD magnitudes on VO2peak performance in healthy compared with unhealthy individuals. With regard to the dose response relationships, findings from the meta-regression showed that none of the included training prescription variables predicted ET effects on VO2peak performance. Conclusions: ET is an effective mean for improving aerobic performance in healthy older adults when compared with their unhealthy counterparts.

Inter-person differences in isometric coactivations of triceps surae and tibialis anterior decrease in young, but not in older adults after 14 days of bed rest
Matjaž Divjak, Gašper Sedej, Nina Murks, Mitja Gerževič, Uroš Marušič, Rado Pišot, Boštjan Šimunič, Aleš Holobar, 2022, izvirni znanstveni članek

Povzetek: We examined activation patterns of the gastrocnemius medialis (GM), gastrocnemius lateralis (GL), soleus (SO), and tibialis anterior (TA) muscles in eight older (58.4 ± 3.3 years) and seven young (23.1 ± 2.9 years) participants, before and after 14 days of horizontal bed rest. Visual feedback on the exerted muscle torque was provided to the participants. The discharge patterns of individual motor units (MUs) were studied in three repetitions of isometric plantar flexion at 30 and 60% of Maximum Voluntary Contraction (MVC), before, and 1 day after the 14-day bed rest, respectively. In the GL and GM muscles, the older participants demonstrated higher MU discharge rates than the young, regardless of the contraction level, both before and after the bed rest. In the TA and SO muscles, the differences between the older and young participants were less consistent. Detailed analysis revealed person-specific changes in the MU discharge rates after the bed rest. To quantify the coactivation patterns we calculated the correlation coefficients between the cumulative spike trains of identified MUs from each muscle, and measured the root mean square difference of the correlation coefficients between the trials of the same session (intra-session variability) and between different sessions (inter-session variability) in each participant (intra-person comparison) and across participants (inter-person comparison). In the intra-person comparison, the inter-session variability was higher than the intra-session variability, either before or after the bed rest. At 60% MVC torque, the young demonstrated higher inter-person variability of coactivation than the older participants, but this variability decreased significantly after the bed rest. In older participants, inter-person variability was consistently lower at 60% than at 30% MVC torque. In young participants, inter-person variability became lower at 60% than at 30% MVC torque only after the bed rest. Precaution is required when analyzing the MU discharge and coactivation patterns, as individual persons demonstrate individual adaptations to aging or bed rest.

Decomposition of tensiomyogram and comparison with torque twitch responses after post-activation potentiation
Ensar Abazović, Armin Paravlić, Damir Zubac, Erol Kovačević, Boštjan Šimunič, 2022, izvirni znanstveni članek

Povzetek: Objectives: This study evaluates the effect of post-activation potentiation (PAP) after 5x5s maximal voluntary isometric contractions (activation stimulus, AS) on tensiomyography (TMG) and torque twitch contractile parameters of vastus lateralis (VL) and medialis (VM), respectively. Further, we validated the decomposition of TMG response to separate responses of three fiber types. Methods: 15 healthy individuals participated in this study (40% women; age 19±2.3 years). A decomposition of VL TMG response was done after optimal fitting of three exponential curves. Results: We found main effects in contraction time (Tc) for muscle, method and time. Furthermore, we found interactions between muscle*method, method*time and muscle*method*time. Compared to PRE AS, we found shorter TMG Tc in VL and VM during the first two minutes after AS. Torque Tc remained unchanged in VL, while it increased in VM within 30 seconds after AS. A decomposition of VL TMG response confirmed PAP effects being present only in decomposed type IIb muscle fibers. Conclusion: The TMG is a sensitive method to detect PAP effects with a sensor mounted directly above the muscle belly. After the decomposition of the TMG signal to three separate muscle fiber phenotypes, we provided a non-invasive insight in the contribution of each muscle fiber phenotype to the PAP of the whole muscle.

Benefits of active life in student experiences during COVID-19 pandemic time
Saša Pišot, Ivana Milovanović, Darko Katović, Sunčica Bartoluci, Sandra Radenović, 2022, izvirni znanstveni članek

Povzetek: The first wave of the COVID-19 pandemic has led to extreme global consequences. In this paper, changes in the basic segments of students' everyday life and their subjective perception are investigated. The research was conducted in Croatia, Serbia and Slovenia. The application of the mixed method was performed to provide breadth and depth of understanding of students' responses to lifestyle changes. The research was conducted in two phases: a quantitative, using an online survey (N = 1,053), from April 15th to April 28th 2020, and a qualitative, using semi-structured interviews (N = 30), from June 10th to July 27th 2020. Students showed similar responses to the measures, but it turned out that the response in that population was different when their gender and study program were taken into account. The results suggest that students of study programs that are not “health-related” were more sensitive to change in habits than students of “health-related” study programs, but generally changes are visible in sleep patterns (going to bed late and waking up 60 to 80 min earlier). At the same time, the time spent in front of screens increased, from M = 4.49 (SD = 2.72) hours to M= 8.27 (SD = 3.44) hours during Covid-19, not only due to the transition to e-learning, but also due to a “stay at home” measure. Furthermore, students were less physically active, there was a decrease in exercise by 20 min (SD = 86.52) and a decrease in walking (M = 54 min, SD = 103.62) per day, and what is positive is that they were able to maintain the recommended amount of physical activity. The research contributes to the understanding of social consequences of extraordinary measures in students as young, healthy and highly educated social actors, as well as deeper insight into everyday strategies they undertake to counter or adapt to the new situation.
