@article{63881, abstract = {{Abstract The relationship between leptin levels and psychiatric disorders has been studied more extensively in adults than in children and adolescents. However, the results are conflicting. We investigated serum leptin levels in children and adolescents (11 to 18.9 years) with psychiatric disorders ( n  = 363). Absolute and relative (body-mass-index (BMI)-, sex- and pubertal-stage-adjusted z-scores using reference values of healthy children and adolescents) leptin levels of different patient groups according to diagnosis were compared. The association between leptin levels and depression (Beck Depression Inventory-II) and anxiety (Child Behavior Checklist and Youth Self Report) was examined using regression analysis. Leptin z-scores were higher in patients with psychiatric disorders than in healthy controls (median 1.50, p  < .001). While global tests suggested differences in leptin z-scores between patients with different psychiatric disorders, these differences could not be attributed to diagnosis groups in post-hoc pairwise comparisons. Absolute leptin levels differed between psychiatric disorders ( p  < .001). Patients with anorexia nervosa (AN) had the lowest levels, and patients with mood disorders had higher leptin levels than patients with mental disorders other than mood disorders, anxiety or AN. Neither absolute nor relative leptin levels were related to depressive or anxiety symptoms in regression models adjusted for sex and BMI. Significantly elevated BMI-, sex- and puberty-stage-adjusted leptin levels were observed in children and adolescents with psychiatric disorders compared to a reference sample. Further controlled studies are needed to confirm and explain this finding. No relationship was found between absolute or relative leptin levels and symptoms of depression or anxiety. }}, author = {{Albers, Nicola and Antel, Jochen and Föcker, Manuel and Libuda, Lars and Bühlmeier, Judith and Hirtz, Raphael and Seitz, Jochen and Hinney, Anke and Hebebrand, Johannes and Peters, Triinu}}, issn = {{1018-8827}}, journal = {{European Child & Adolescent Psychiatry}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Children and adolescents with psychiatric disorders have high relative leptin levels upon adjustment for sex, BMI, and pubertal status}}}, doi = {{10.1007/s00787-025-02921-4}}, year = {{2026}}, } @article{63880, author = {{Knoll-Pientka, Nadja and Schils, Dorina and Mantwill, Katrin and Dinse, Hannah and Skoda, Eva-Maria and Bäuerle, Alexander and Teufel, Martin and Libuda, Lars}}, issn = {{2055-0928}}, journal = {{BMC Nutrition}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Adherence to dietary recommendations according to the General Dietary Behavior Inventory (GDBI) and its association with bioelectrical impedance analysis (BIA) parameters among young, healthy and normal weight women}}}, doi = {{10.1186/s40795-026-01260-0}}, year = {{2026}}, } @article{64609, author = {{Kehne, Miriam and Anne-Christin, Roth}}, journal = {{Grundschule Sport}}, number = {{1}}, pages = {{20--21}}, title = {{{Qualitätsentwicklung im Ganztag.

Participants were generally instructed to initiate the movement as fast and accurately as possible, while try-harder instructions were presented in 25 % of trials, prompting participants to mobilize all their cognitive resources to perform even faster. To investigate if athletic expertise modulates the potential effects of effort mobilization, basketball novices and experienced players were tested. Results demonstrated that try-harder instructions generally improved participants’ performance, facilitating faster response initiation times and movement execution, as well as a specific reduction in initiation time variability. Novices benefited more than experienced players, indicating that effort results in greater improvement when complex motor actions (for example, passes with head fakes) are not yet fully stabilized and lack automated fluency. This pattern suggests that effort enhances performance in complex actions when performance is limited by the amount of cognitive capacity available, supporting the coordination of partly conflicting movement components within tight temporal constraints. The findings extend previous research on effort mobilization from simple to complex motor tasks. Try-harder instructions appear to enhance performance primarily by reducing attentional lapses rather than generally improving processing speed. Future research should investigate the effectiveness of effort mobilization in experienced athletes in situations of high concurrent cognitive load.}}, author = {{Böer, Nils Tobias and Steinborn, Michael B. and Weigelt, Matthias and Güldenpenning, Iris}}, issn = {{1469-0292}}, journal = {{Psychology of Sport and Exercise}}, keywords = {{Effort, Try-harder instruction, Deception, Basketball, Head fake, Fake production}}, publisher = {{Elsevier BV}}, title = {{{Mobilizing effort in complex motor tasks: Try-harder instructions in deceptive actions}}}, doi = {{10.1016/j.psychsport.2026.103083}}, volume = {{84}}, year = {{2026}}, } @article{63563, abstract = {{ Introduction Age-related changes in brain signal complexity are associated with cognitive decline and reduced neural adaptivity in older adults. Exergaming offers a promising prophylactic intervention combining physical and cognitive training. The aim of the present study was to assess how exergaming alters the temporal trajectory of brain signal complexity at rest and during gameplay in older adults. Methods Twenty-eight healthy older adults participated in a 4-week exergaming intervention. Electroencephalography was recorded using 64 electrodes at rest (pre- and post-intervention) and during exergaming (pre-, mid-, and post-intervention). Brain signal complexity was quantified using multiscale entropy across 64 time scales on preprocessed signals. Results Post-intervention resting-state analysis revealed significant reductions at fine and increases at coarse scales in frontal, central, and posterior entropy. During gameplay, entropy declined widespread by mid-intervention, particularly at coarse scales over frontal, central and temporal regions. From mid- to post-intervention, the decline narrowed leaving a net pre-to-post reduction concentrated at coarse scales in these regions. Discussion Resting-state changes indicated a shift toward a younger brain profile, characterized by a transition from age-related increases in local processing to enhanced distributed processing, which may potentially mitigate the rise in neural modularity associated with aging. During gameplay, brain signal complexity decreased in week 2, followed by a modest change by week 4, consistent with the framework in which complexity initially streamlines and then adjusts toward a task-specific optimum. These findings suggest that exergaming can beneficially modulate brain complexity in older adults, offering the potential to reduce age-related neural decline and support healthy brain aging. }}, author = {{Piskin, Daghan Yüksel and Müller, Helen Martha and Skjæret-Maroni, Nina and Vereijken, Beatrix and Baumeister, Jochen}}, issn = {{1663-4365}}, journal = {{Frontiers in Aging Neuroscience}}, publisher = {{Frontiers Media SA}}, title = {{{Rewiring the aging brain: exergaming modulates brain complexity in older adults}}}, doi = {{10.3389/fnagi.2025.1748274}}, volume = {{17}}, year = {{2026}}, } @book{61869, abstract = {{There are few things left on earth that people have not attempted to measure. From temperature to time, from finances to football, numbers are a crucial mediator of how we perceive and understand the world we live in.

But what does it do to us to be on the receiving end of such measurement? One of the world’s most successful global metrics is the school grade. Long predating the digital age, educational marks can be traced back at least to sixteenth-century European schools and have since conquered the world, becoming the indicator of academic achievement. To understand what it means to be quantified, Noëlle Rohde undertook in-depth fieldwork in a German comprehensive school where students receive more than one hundred grades per year. By staying close to the pupils as they are continually examined and assessed, her ethnography illustrates how marks mould students’ self-images, how they enforce meritocratic thinking and serve as a potent disciplinary tool.

The purpose of this longitudinal, prospective study was to investigate whether potential structural and/or functional alterations within the brain were associated with (high-magnitude) heading. Methods 3T MRI sequences were obtained from active high-level male players before and after an observation period of 17.2 months (median). Cortical thickness and grey matter (GM) volume were investigated on a whole-brain level. Functional connectivity (FC) was analysed in the default mode network (DMN) and salience network (SN). During the observation period, each training and each match was videotaped and evaluated regarding the heading exposure. Significant structural and functional findings were subsequently correlated with specific header characteristics. Results 14 included participants (mean age: 20.36±3.34 years) played 5822 headers. GM volume remained unchanged, whereas cortical thickness decreased minimally from pre-measurement to post-measurement in a left precentral region (mean change: 0.048±0.128 mm; clusterwise p=0.0416). Within the SN, FC increased in one cluster (false discovery rate corrected p=0.026). FC remained stable within the DMN and between DMN and SN. Change from pre-measurement to post-measurement for the significant results did not correlate with heading variables. Conclusion Our findings may indicate no cumulative effect of heading during the observation period. As these results contrast with cross-sectional findings, more longitudinal, prospective studies with a greater sample size are urgently needed to understand potential heading effects. }}, author = {{Mund, Franziska Katharina and Feddermann-Demont, Nina and Welsch, Goetz H and Schuenemann, Carsten and Fiehler, Jens and Thaler, Christian and Meyer, Lukas and Reeschke, Rebecca and Reinsberger, Claus}}, issn = {{2055-7647}}, journal = {{BMJ Open Sport & Exercise Medicine}}, number = {{4}}, publisher = {{BMJ}}, title = {{{High-magnitude headers are not associated with structural and functional brain changes in active high-level football (soccer) players}}}, doi = {{10.1136/bmjsem-2025-002636}}, volume = {{11}}, year = {{2025}}, } @article{63882, author = {{Dinkelbach, Lars and Wudy, Stefan A. and Hartmann, Michaela F. and Libuda, Lars and Föcker, Manuel and Hebebrand, Johannes and Hinney, Anke and Nöthlings, Ute and Alexy, Ute and Grasemann, Corinna and Hirtz, Raphael}}, issn = {{0165-0327}}, journal = {{Journal of Affective Disorders}}, publisher = {{Elsevier BV}}, title = {{{Urinary steroid metabolome shows adrenal, gonadal, and neuroactive steroid dysregulation in adolescents with depressive symptoms}}}, doi = {{10.1016/j.jad.2025.120867}}, volume = {{399}}, year = {{2025}}, } @article{58238, abstract = {{Abstract Anterior cruciate ligament injuries (ACLi) impact football players substantially leading to performance declines and premature career endings. Emerging evidence suggests that ACLi should be viewed not merely as peripheral injuries but as complex conditions with neurophysiological aspects. The objective of the present study was to compare kicking performance and associated cortical activity between injured and healthy players. Ten reconstructed and 15 healthy players performed a kicking task. Kicking biomechanics were recorded using wearable inertial measurement unit sensors. Cortical activity was captured with a 64-electrode mobile electroencephalography. Multiscale entropy (MSE) analysis of biomechanics revealed increased variability in foot external rotation among injured players. Source-derived event-related spectral perturbations indicated significant differences in posterior alpha and frontal theta oscillations between the two groups. Furthermore, kick-related complexity of these regions as indexed by MSE was reduced in injured players at medium and coarse scales. Our findings suggest sensorimotor changes during kicking in injured players, which may necessitate compensatory strategies involving augmented attention at the cost of processing visuospatial information. This conflict may hinder the integration of task-relevant information across distributed networks.

Therefore, this study aimed to investigate the impact of a compliant surface on cortico-cortical causal information flow during multi-joint compound movements. Fifteen healthy adults (7 female / 8 male, 25.9 ± 4.0 years) performed 5 × 20 repetitions of bodyweight squats on firm and compliant surface. Motor behavior was quantified by center of pressure (CoP) displacements, hip movement and the root mean square of the rectus femoris activity. Using source space analysis, renormalized partial directed coherence (rPDC) computed subject-level multivariate effective brain connectivity of sensorimotor nodes. Bootstrap statistics revealed significantly decreased medio-lateral CoP displacement (p < 0.001), significantly increased velocity of medio-lateral hip motion (p < 0.001) as well as significantly lower rectus femoris activity (p < 0.01) in the compliant surface condition. On the cortical level, rPDC showed significantly modulated information flow in theta and beta frequencies for fronto-parietal edges (p < 0.01) only during the concentric phase of the movement. The compliant surface led to increased difficulties controlling hip but not center of pressure motion in the medio-lateral plane. Moreover, a decreased activation of the prime movers accompanied by modulations of effective brain connectivity among fronto-central nodes may point to altered demands on sensorimotor information processing in presence of sensory noise when performing bodyweight squats on compliant surface.
