However, the associations in older adults remain unclear. This study aimed to determine the same-day association between sleep (duration and quality), physical activity (stepping) and sedentary behaviors (sitting and lying), and affect (positive and negative affect) among older adults using ecological momentary assessment (EMA).\u0000The data collection period was 14 consecutive days. Sleep logs collected sleep duration, while smartphone surveys collected sleep quality and momentary affects. The ActivPAL4 accelerometers computed daily sedentary and physical activity (PA) times. Affects were regressed on the sleep and movement-based behaviors using two separate mixed-effects models, controlling for demographics.\u0000Ninety older adults were included in the analysis: female (n = 56, 62%), white (n = 71, 79%) age (M = 68.16 yrs, SD = 6.47), sedentary time (M = 10.13 hrs/day, SD = 2.00), PA time (M = 1.60 hrs/day, SD = 0.65), sleep duration (M = 8.25 hrs/day, SD = 1.39), and sleep quality (M = 6.92/day, SD = 1.39). More sedentary, PA time, and better sleep quality than usual on a given day were associated with both lower negative affect (bs range = -0.18 – -0.02, ps range = .001 – .025) and higher positive affect (bs range = 0.05 – 0.14, p < .001). The longer sleep duration than usual on a given day was associated with lower negative affect (b = -0.06, p < .001).

Cuthbert, Chakaveh Ahmadizadeh, Carlo Menon","doi":"10.36950/2024.2ciss086","DOIUrl":"https://doi.org/10.36950/2024.2ciss086","url":null,"abstract":"Introduction\u0000Textile wearable systems for human movement monitoring are increasingly popular. However, few examples report on robustness to sweat, which is relevant for use in real life. Some reported the effect of artificial sweat like phosphate buffered saline (PBS; Lin et al., 2022) or simply moisture (Xu et al., 2020) on custom materials. We previously developed an all-textile wireless sensing platform with commercial conductive yarns and fabrics containing silver. There is no study on the effect of sweat on such materials, therefore we performed a preliminary study to account for moisture and potential oxydation of silver.\u0000Methods\u0000The textile sensing system is resonating RLC circuit, where the sensing part is a capacitive parallel plate strain sensor (C) located on a joint (knee). All components are textile based and contain silver. As the capacitive sensor stretches, capacitance increases and the resonance of the circuit fres decreases. This information is transmitted wirelessly via inductive coupling (Galli et al., 2023). We sprayed 1 ml of 0.1 M PBS solution on the textile capacitive sensor to simulate sweating, and applied mechanical strain before (damp state) and after air drying (dry state). The unmodified sensor (before the addition of any PBS) was also used as a baseline measure. First, we applied fixed strain (10%) with a universal testing machine; then, we tested the response of the sensorized pants when bending the knee.\u0000Results The resonance frequency of the textile sensing (RLC) circuit in the damp state was much lower than the baseline (14.85 ± 0.11 MHz vs 22.70 ± 0.12 MHz) as expected from the higher dielectric constant of water that increases the baseline capacitance of the sensor. As for the change in Δfres upon 10% strain (Δfres = fres,baseline - fres,stretch), interestingly a larger change was observed for the damp configuration as compared to the baseline and dried (1.08 ± 0.08 vs 0.79 ± 0.06 vs 0.66 ± 0.03 MHz). A similar behaviour was observed in the test with pants, where the response for flexion was Δfres = 1.58 MHz for the damp sensor and Δfres = 1.28 MHz for the dried sensor.\u0000Discussion/Conclusion\u0000This preliminary investigation showed promising results in terms of robustness of our system to artificial sweat, as there was a measurable response both in the damp and dried configurations. Further tests with different sweat amounts and rate are needed to determine the full functioning range, e.g., how much sweat is tolerated.\u0000References\u0000Galli, V., Sailapu, S. K., Cuthbert, T.

{"title":"Finger-specific representations are sharpened during a fatiguing motor task","authors":"Caroline Heimhofer, Susanne Koblitz, M. Bächinger, Nicole Wenderoth","doi":"10.36950/2024.2ciss048","DOIUrl":"https://doi.org/10.36950/2024.2ciss048","url":null,"abstract":"Introduction \u0000Motor fatigability is a limiting factor in any kind of setting, in which physical performance is required. Motor fatigability can be quantified through the decrease in movement speed, when low-force movements are performed repeatedly with maximal speed. In this study, we measure motor fatigability in healthy participants through fast finger tapping for 30s. Previous research has shown that the decrease in movement speed, also called motor slowing, is associated with a rise in brain activity, a reduction in surround inhibition in the primary sensorimotor cortex (SM1), and an increase in co-activation of antagonistic muscle groups involved in the movement (Bächinger et al., 2019). However, it remains an open question of whether motor slowing and the associated release of inhibition causes a reduction of signal-to-noise ratio for movement-specific information. Here, we aim to answer this question by assessing finger representations using representational similarity analysis (RSA) when participants perform fatiguing tapping with either the index or middle finger. We hypothesized that a reduction of movement-specific information would be associated with the index and middle finger representations in SM1 getting “blurred” over time due to a gradual break-down of surround inhibition. Thus, if the signal-to-noise ratio of movement-specific information decreases in parallel with motor slowing, we would expect finger representations to become more overlapping. Vice-versa, if the signal-to-noise ratio of movement-specific information increases despite motor slowing, we would expect sharper finger representation. \u0000Methods \u000026 healthy young participants performed a motor slowing task during functional MRI. The participants performed 30s of maximal speed finger tapping with the index and the middle finger, alternating between trials. To quantify motor slowing from the behaviour, we performed a linear regression analysis. For the first-level general linear model of the fMRI data, the fingers were regressed separately and the 30s of tapping were further split into 3 x 10s regressors (time bin 1, bin 2, bin 3). We performed RSA separately on each 10s regressor for the anatomically defined regions of interest M1 and S1 hand area (Diedrichsen et al., 2013; Walther et al., 2016) and therefore obtained a dissimilarity measure for each time bin. A mixed effects model with the factor time was used to test whether dissimilarity changed across time bins. \u0000Results \u0000On the behavioural level, motor slowing could be observed, as tapping speed significantly decreased in each finger over time (F(1, 76) >= 5.78, p <=.05). Concerning the dissimilarity measure, we found an increase over time for S1 as well as M1 (F(2, 50) >= 17.41, p <=.001). \u0000Discussion/Conclusion \u0000We conclude that the finger representations in the sensorimotor cortex become more distinct with motor slowing.

A conceptual framework on the agenda setting process based on a multiple case study","authors":"Sara Piller, Siegfried Nagel","doi":"10.36950/2024.2ciss065","DOIUrl":"https://doi.org/10.36950/2024.2ciss065","url":null,"abstract":"Introduction \u0000In Europe, more than 60 million people practice sport in a club. Through the consumption behaviour of this large number of sport club members, organised sport not only has positive impacts, but can be deleterious to the environment, for example through travel behaviour or the destruction of natural habitats caused by sport activities and required infrastructure (McCullough et al., 2020). National sport federations, which represent sport clubs and engage in sport policy issues, could be crucial when it comes to taking measures concerning the environmental sustainability of and through organised sport. However, sport federations are traditionally committed to the interests of their members and sport as their core business (Thiel & Mayer, 2009). Therefore, this study addresses the extent to which environmental policies are set on agendas in national sport federations and which drivers are relevant for the agenda setting of such policies. \u0000Methods \u0000To gain a comprehensive and in-depth understanding of these questions, we conducted an explorative qualitative multiple case study with eight Swiss sport federations. To investigate the agenda-setting process in sport organisations, we employed the multiple streams approach by Kingdon (1984). \u0000Results \u0000The developed conceptual framework shows that whereas nature conservation policies were primarily driven by national regulations, climate protection policies were pushed by engaged functionaries of the federations. Functional issues (as opposed to normative arguments), sponsor and member interests, practices of other federations and societal developments could further facilitate or impede the agenda setting of all types of environmental policies. \u0000Discussion/Conclusion \u0000This study provides valuable insights into the drivers of the agenda setting of environmental policies in national sport federations. Furthermore, it outlines the fit and limitations of the multiple streams approach according to Kingdon (1984) to explain agenda setting processes in national sport federations and extends it by external factors to gain a more holistic perspective of the phenomenon. Understanding drivers in the agenda setting of environmental policies in national sport federations is especially important because it is a prerequisite for the subsequent decision making and implementation of such policies and can help to shape the response of the organised sport to environmental challenges. \u0000References \u0000Kingdon, J.

One way to bring more light into this question is to tests the effect of a single task training (STT) and a dual task training (DTT) on the short interval intracortical inhibition (SICI) during a single balancing task and two different dual tasks in healthy young adults. \u0000Methods \u0000Twenty-nine healthy young adults were randomly separated into two groups participating in STT (n = 15) or DTT (n = 14) consisting of 6 training sessions within 3 weeks. Before and after the training, a single task (balancing on a rocker board) was performed at two resistance levels (easy and hard). Additionally to the single task, either a cognitive (2-back number recall) or a motor (balancing a ball on a hand-held tray) dual task was executed simultaneously. During execution of these three tasks, SICI was measured with transcranial magnetic stimulation over the motor cortical area representing the right tibialis anterior. \u0000Results \u0000Training improvements in balance performance were group and task-specific over time (p = .018). While the STT group improved more in the single balance task (12.3% vs. 6.6% DTT), the DTT group had more sway reductions in the motor dual task condition (13.7% vs. 4.5% STT). Similar statistical outcome (p = .034) was observed for the dual task costs (DTC). There was a tendence for SICI (p = .075), mainly indicating higher increase in SICI for the DTT group in the motor dual task (16.0% vs. 5.8% STT). During the execution of the single balance task, the group-specific adaptations in SICI were less pronounced (13.7% DTT vs. 16.2% STT). When analyzing the SICI dual task difference (Δ) from single to dual task, SICI is altered group and task specific (p = .011). The DTT group could increase the dual task difference in SICI in the dual motor condition (Δ 3.2%), whereas the STT group had a decrease (Δ -9.6%). \u0000Discussion/Conclusion \u0000The results of this study show that DTT causes gains in balance performance and increases in SICI when the secondary task is also a motor task, but not when the second task is a cognitive one. STT is particularly beneficial in the single task. It is therefore assumed that intracortical inhibition is important during the simultaneous performance of two motor tasks, while intracortical inhibition was not modulated in a group-specific manner by the additional cognitive task. \u0000References \u0000Corp, D.

In comparison, however, boys and young men continue to show a higher level of sporting activity at every age level and in all language regions (Lamprecht et al., 2021). As physical education (PE) lessons are an important socialisation factor for extracurricular sports activities, the question arises as to how PE is taught in Switzerland to do justice to the genders.\u0000To date, there has been little scientific research in Switzerland into which cantons implement coeducational PE and which legal or regulatory bases they rely on. Due to this research gap, this contribution will analyse which cantons implement coeducational PE and to what extent these can be linked to the legal bases or language-regional curricula.\u0000Methods\u0000With the help of a document analysis of the current legal and regulatory bases as well as the three language-regional curricula a national inventory of the existing guidelines is conducted. Furthermore, a qualitative survey of all cantonal school offices analyses the current situation regarding coeducational PE lessons in compulsory education in Switzerland.\u0000Results\u0000The results indicate that there are level-specific, cantonal, and language-regional differences. Language cultural differences are particularly evident at lower secondary school level, since in the German-speaking cantons PE lessons are mostly mono-educational and in the French and Italian-speaking cantons they are usually coeducational (Hayoz, under review).\u0000Discussion\u0000In the German-speaking cantons, especially for lower secondary level, the organisational recommendations given in these curricula are used by the municipalities and schools to make and legitimise their decisions. This recommendation can be critically reflected upon and discussed regarding the holistic educational goals of compulsory schooling, as the aim is to provide competence-orientated PE lessons and to promote interdisciplinary skills. According to Alfermann (1992), it must be questioned why precisely this differentiation feature – and no other heterogeneity feature – is used to divide the existing classes. Although performance is a constitutive characteristic for schools and for sport in general, performance is merely one “pedagogical perspective” among many for PE lessons (Frohn, 2019).\u0000Conclusion\u0000In order to analyse the specific didactic implementation of mono- and coeducational teaching in PE and to better understand the language-cultural differences, further national studies would be necessary at both local as well as school level.\u0000References\u0000Alfermann, D.

On one swing, the inhalation causes an increase of the heart rate, while the opposite effect is during exhaling, thus having variability properties in the inter-beat intervals. By utilizing this effect of respiratory sinus arrhythmia, resonance frequency (RF) gives insight into the respiratory rate at which this resonance is amplified in the heart rate, blood pressure, and respiration systems (Shaffer & Meehan, 2020). The aim of this systematic review was to examine the effects of resonance frequency in Slow-Paced Breathing (SPB) studies, as well as the relation between RF and anthropological measures of gender, height, and age. \u0000Methods \u0000We systematically reviewed the literature regarding the role of resonance frequency in the SPB research using the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) evidence-based reporting checklist and a Participants, Index Test, Comparison, Outcomes, and Study Design (PICOS) framework (PROSPERO Registration Number CRD42021253009). We included SPB studies with experimental and quasi-experimental designs, conducted on healthy populations that determined individual RF in the breathing protocols, with no specific criteria on gender, age restrictions, or publication year. Additionally, interventions combining RF SPB with biofeedback monitoring were included. Outcomes of the included studies included any psychological or physiological findings. Altogether, 17 studies (n = 810 participants) were assessed for risk of bias with The Joanna Briggs Institute Critical Appraisal Checklist (Moola et al., 2015). \u0000Results \u0000Overall, positive effects on psychological constructs like attention control, executive functioning, sleep quality, psychological relaxation, mindful awareness, self-compassion, vigor, self-efficacy, mood, depression, anxiety, and stress have been reported. Physiologically, RF breathing caused a more coherent heart rhythm pattern with high amplitude oscillation, while lowering systolic pressure, decreasing HF power, HR beats per minute, a-amylase and cortisol stress biomarkers, and increasing the average baroreflex gain, SpO2, and LF power. The scarcity of reported data and analysis concerning the effects of anthropological data do not give a strong claim to the existence of height, gender, and age influences, but there is a notion that height and RF are negatively correlated, while men have lower RF than women. \u0000Discussion/Conclusion \u0000We conclude the overall beneficial effects of RF breathing on psychological and physiological systems.

Peters, Xinlin Wang, Martin Dresler, Daniel Erlacher","doi":"10.36950/2024.2ciss006","DOIUrl":"https://doi.org/10.36950/2024.2ciss006","url":null,"abstract":"Introduction\u0000Lucid dreaming opens the possibility to rehearse sport skills within a dream while sleeping (Peters et al. 2023; Stumbrys et al. 2016). But so far, no induction techniques have been developed to induce reliable lucid dreams. One potential technique is to apply external stimulation while a person is sleeping in order to send a hint into the dream which might enhance lucidity in the ongoing dream. Several studies have tested dream incorporation rates (DIR) with different stimuli and different results (Schredl, 2018), but none with a larger sample size and a within-design. Furthermore, in this study we wanted to explore body related stimulations to evoke in future studies lucid dreams.\u0000Methods\u000010-Channel polysomnography and three different bodily stimulation methods were combined during three consecutive test nights with each night using one stimulation method (plus adaptation night). The three stimulation methods consisted of electrical forearm muscle stimulation (EMS), galvanic vestibular stimulation (GVS), and haptic vibration stimulation (HS). During REM sleep, one of the three stimuli was presented or a sham condition was applied in a counterbalanced order. The stimuli were followed by REM awakenings, resulting in corresponding verbal dream reports. With the help of those reports, the translation from a physical arm movement, vestibular sensation and vibration into the dream environment was investigated using dream content analysis. Movement of the dream arm, balance related activity and tactile or somatosensory sensations targeted the dream incorporations of EMS, GVS and HS respectively.\u0000Results\u0000Movement of the arm was present in 23.2%, 8.1% and 23.5% of EMS, GVS and HS dreams respectively. Balance-related activity was present in 6.1%, 7.9% and 5.8% of EMS, GVS and HS dreams respectively. Finally, tactile and somatosensory sensations were present in 13.6%, 0% and 6.3% of the EMS, GVS and HS dreams respectively. After correcting for sham condition, tactile and somatosensory sensations on the EMS dreams seem to be the strongest incorporation effect upon stimulation.\u0000Discussion/Conclusion\u0000We tested dream incorporation of three different stimulation methods using a within-design on a larger sample size, a method that has never been attempted before. GVS appears unsuccessful in altering dream content, but this might be confounded due to challenges in methodology. EMS evokes the most dream incorporation in the scale of tactile and somatosensory dream content followed by HS. The investigation of the incorporation of external kinesthetic stimulation into dream content represents a fundamental contribution to various scientific fields and could foster future research on lucid dream induction, enabling the further exploration of sport practice in a sleep state.\u0000References\u0000Peters, E., Golembiewski, S., Erlacher, D., & Dresler, M.
