@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.

Basketball passing movements with and without head fakes were examined in a reaction-time paradigm. 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{65443, abstract = {{Abstract Social media is integral to adolescents’ daily lives and plays an important role in their health- and fitness-related behavior, particularly through trends such as #fitspiration, a portmanteau of “fit” and “inspiration.” This trend has become a prominent aspect of adolescents’ fitness culture. Empirical studies demonstrate that while #fitspiration holds the potential to motivate adolescents to be physically active, it also perpetuates gender-stereotyped, predominantly White, ableist, and normative body ideals associated with fitness and an idealized weight. This trend can be linked to an increased risk of body image concerns or disordered eating among adolescents. Understanding adolescents’ engagement with fitspiration content is crucial for tailoring health and media literacy education within physical education. Therefore, a systematic review of qualitative and quantitative studies was conducted. A search of five electronic databases yielded 312 abstracts, of which 12 met the inclusion criteria. The analysis of the selected studies was based on thematic analysis and included both primary and secondary data. Seven analytical themes emerged: (1) 37–56% of adolescents actively engage with fitspiration content on social media; (2) it fulfills their need for informal and accessible participation; (3) it fosters a sense of social connection; (4) they derive inspiration from peers and influencers; (5) they aspire to idealized body standards; (6) they seek quick solutions when dissatisfied with their bodies; and (7) a few become demotivated and critical when unable to achieve these ideals. Consequently, educators should balance the potential benefits with media literacy interventions to mitigate risks such as body image issues and eating disorders.}}, author = {{Grimminger-Seidensticker, Elke and Korte, Johanna}}, issn = {{2509-3142}}, journal = {{German Journal of Exercise and Sport Research}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Adolescents’ engagement with #fitspiration content—a systematic review of qualitative and quantitative studies and pedagogical implications for physical education Der Umgang von Jugendlichen mit Inhalten zu #fitspiration - Ein systematisches Review qualitativer und quantitativer Studien sowie pädagogische Implikationen für den Sportunterricht}}}, doi = {{10.1007/s12662-026-01107-7}}, year = {{2026}}, } @inbook{65549, author = {{Grimminger-Seidensticker, Elke and Ehrlenspiel, Felix and Hepperle, Lisa}}, booktitle = {{Schulsport.

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}}, } @article{65935, author = {{Piskin, Daghan Yüksel and Cobani, Gjergji and Büchel, Daniel and Lehmann, Tim and Baumeister, Jochen}}, issn = {{0361-9230}}, journal = {{Brain Research Bulletin}}, publisher = {{Elsevier BV}}, title = {{{Brain complexity in motion: Multiscale entropy analysis on mobile EEG data to assess motor performance}}}, doi = {{10.1016/j.brainresbull.2026.111769}}, volume = {{236}}, year = {{2026}}, } @inbook{59456, author = {{Neuber, Nils and Kaufmann, Nils and Kehne, Miriam and Noetzel, Ida and von Plettenberg, Elisabeth and Satzinger, Nicole and Schröder, Stefan and Süßenbach, Jessica}}, booktitle = {{Potenziale von Bewegung, Spiel und Sport für ein gesundes Aufwachsen in Deutschland.
