Background/Objectives: Adherence to the 24-h movement guidelines is generally low in preschool children, and less is known about how proximal family support for children’s physical activity (family PA support) is associated with physical fitness and 24-h movement behaviors. This study aimed to describe guideline adherence and to examine the associations among family PA support, 24-h movement behaviors, and physical fitness in Chinese preschool children. Methods: This cross-sectional study included 2386 Chinese preschool children (4.50 ± 0.86 years, 46.8% girls). Family PA support and 24-h movement behaviors were assessed using parent-reported questionnaires, and physical fitness was assessed using the Chinese National Physical Fitness Evaluation Standard for preschool children. Path analysis was used to examine the overall association pattern, including direct and indirect association estimates, among family PA support, movement behaviors, and physical fitness. Results: Only 12.7% of preschool children met all three 24-h movement recommendations. Compliance was 24.7% for physical activity, 82.7% for screen time, and 76.8% for sleep, indicating that insufficient physical activity was the main barrier to full guideline adherence. Family PA support was positively associated with physical fitness (β = 0.048, p = 0.021), and the combined indirect association estimate involving the three movement behaviors was also statistically significant (β = 0.024, p < 0.001). Among the three movement behaviors, family PA support was most strongly associated with higher MVPA (β = 0.150, p < 0.001), and MVPA showed the clearest positive association with physical fitness (β = 0.155, p < 0.001). Screen time was negatively associated with family PA support (β = −0.088, p < 0.001) but not significantly associated with physical fitness (p = 0.091), whereas sleep showed a small negative association with physical fitness (β = −0.056, p = 0.005). These findings suggest a comparatively stronger role for MVPA within the observed association pattern. Conclusion: Chinese preschool children showed low adherence to the 24-h movement guidelines, with insufficient physical activity appearing to be the main limiting factor. Family PA support may represent a potentially modifiable family-level correlate of preschool children’s physical fitness, with MVPA appearing to play a comparatively stronger role within the observed association pattern.

This study was based on a 30 m inside-foot long-pass scenario and aimed to preliminarily evaluate the agreement between MediaPipe Pose, DWPose, YOLO-Pose, and Xsens, as well as their practical utility under real-field conditions. Twelve elite male football players performed 15 consecutive long-passes, with data collected simultaneously using Xsens and two smartphones positioned at 15° and 35° to the right front of the participants. The Intraclass Correlation Coefficient (ICC (2,1)) and Bland–Altman analysis were used to evaluate discrete kinematic measures. Continuous kinematic agreement was assessed using Root Mean Square Error (RMSE) and the Coefficient of Multiple Determination (CMD), while Statistical Parametric Mapping (SPM) and Statistical non-Parametric Mapping (SnPM) compared differences across the entire analysis interval. Across the three models, CMD ranged from 0.13 ± 0.17 to 0.67 ± 0.25, and RMSE ranged from 9.88 ± 8.20° to 39.92 ± 10.44°. The SPM and SnPM results showed that significant differences were mainly concentrated in the bilateral hip, knee, and ankle joints. The three models cannot yet be used for field-based high-precision kinematic data measurement; however, MediaPipe Pose and DWPose may be selectively used for rapid screening of movement patterns and analysis of movement trends in football-specific technical movements.

Background: Preseason screening is widely used in handball to identify athletes at increased risk of injury, yet the prognostic value of different screening approaches remains unclear. The aim of this study was to systematically review the evidence on preseason screening tests and physical assessments in relation to subsequent injury outcomes in handball players. Methods: A systematic review was conducted according to PRISMA guidelines. PubMed, MEDLINE, CINAHL, and Scopus were searched on 14 March 2026. The first 100 results from Google Scholar were also screened, and backward citation searching was performed. Eligible studies included handball players and examined preseason or baseline screening, functional, musculoskeletal, or physical performance assessments in relation to prospectively recorded injury outcomes. Two independent reviewers performed study selection, data extraction, and risk-of-bias assessment using the QUIPS tool. Due to substantial heterogeneity in screening tools, injury outcomes, and follow-up procedures, meta-analysis was not performed. Results: Eight studies were included. Most were prospective cohorts involving adolescent, youth elite, or elite adult handball players. Shoulder-specific screening variables, particularly external rotation strength, strength imbalances, total rotational motion, and selected rotational adaptations, showed more consistent associations with subsequent shoulder-related outcomes. In contrast, broader movement-screening tools, including the Functional Movement Screen, the 9+ screening battery, and the upper quarter Y-Balance Test, generally showed limited associations with overall injury outcomes. Conclusions: Shoulder-specific preseason assessments may be more closely associated with subsequent shoulder-related outcomes than broader movement-screening tools, although the available evidence remains limited, heterogeneous, and derived exclusively from observational studies.

Notwithstanding the cruciality of the decolonisation project in decentring African perspectives and experiences in education, very few studies have explored the extent to which the Fallist Movements in South Africa have presented foundational pathways for academic staff to negate colonial legacies and recentre African thought systems. Through a systematic literature review of research from the public domain, this study couched within the decolonial lens explored university students’ concerns, embedded in the Fallist Movements in South Africa, and how academic staff could draw lessons from student actions to decolonise education. After screening the initial 65 entries, based on the exclusion and inclusion criteria, 19 research studies published between 2015 and 2025 were retained for analysis. Findings reveal three recurring concerns: disrupting positionality in colonial categories of universities, reasserting their Being, and agitating for a decolonised curriculum, of which these embodied the spirit of students’ resilience against cultural colonisation, epistemic erasure, and economic exclusion. Building on these findings, the paper argues that such resilience from students enlightens the strategies academic staff could learn to transform the decolonisation project into reality. Implications for the academic community in South Africa and comparable contexts are proposed to resuscitate the unfinished business of decolonising education. Full article

Virtual avatars have shown potential as supports in Autism Spectrum Disorder (ASD) interventions, but many existing systems provide largely standardized interactions that do not account for individual variability. This study presents an exploratory evaluation of a virtual puppet system that enables real-time interaction by synchronously transmitting a human model’s movements, facial gestures, and voice to a digital avatar. The system was personalized using each participant’s restricted interests (RIs), identified through a clinical triangulation process involving therapist input, caregiver reports, and observation. After an initial technical validation with 16 neurotypical children, the system was evaluated in a proof-of-concept sample of 11 children with ASD (7 in an experimental group exposed to RI-based personalization and 4 in a control group interacting with a standard interface). Data sources included eye tracking and therapist-completed observational questionnaires. Across sessions, descriptive patterns in gaze fixation and therapist reports suggested that RI-based personalization may help sustain attention to the screen and support engagement with the therapeutic environment relative to non-personalized interaction. Heatmap patterns further indicated that children under the personalized condition visually explored RI-related elements within the scene. This study provides evidence of technical and procedural feasibility and generates hypotheses for future research. Full article

Airport systems rely on tightly connected digital and physical components, so cyber disruptions can affect both service performance and passenger movement. Existing airport simulation studies often focus on either queue-based passenger processing or pedestrian movement but rarely combine both in a framework suited for cyber-resilience analysis. This paper presents a hybrid simulation framework that integrates discrete-event simulation (DES), JuPedSim-based microscopic pedestrian modeling, and structured large language model (LLM) decision support to examine how cyber disruptions propagate through passenger-facing airport operations. The DES layer models service processes such as check-in, information desks, and security screening, while the pedestrian layer models movement, congestion, route choice, and spatial occupancy. Under degraded display or guidance conditions, the LLM generates structured passenger-level post-security decisions, such as going directly to the gate, checking a display, asking staff, waiting, visiting optional activity areas, or first moving to a wrong intermediate area. The framework is evaluated through a 500-passenger terminal case study with one baseline case and four disruption cases. Results show that check-in and security degradation produce the largest throughput loss, queue growth, and completion-time increase, while guidance degradation mainly affects post-security behavior. Spatial heatmaps further show where bottlenecks emerge and how congestion shifts across the terminal. Additional Rotterdam checkpoint validation, Palma benchmark analysis, and LLM ablation results support the framework’s ability to reproduce plausible queue, timing, throughput, and behavior-sensitive disruption patterns. The study provides a practical methodology for exploratory airport cyber-resilience assessment under coupled service, movement, and degraded-guidance conditions. Full article

Background: Trunk and pelvic strength balance and functional movement quality are relevant factors for musculoskeletal health and injury-prevention monitoring in youth soccer players. Aim: This study aimed to evaluate longitudinal changes in isometric trunk and pelvic strength balance, functional movement quality, and selected muscle imbalance indicators during a physiotherapy-based strengthening programme in adolescent male soccer players. Methods: A longitudinal single-group repeated-measures study was conducted in male soccer players aged 12–18 years. Isometric strength balance was assessed using the Dr. Wolff Back-Check system, and functional movement quality was evaluated using the Functional Movement Screen (FMS). Complete-case analyses were performed according to available repeated measurements. Results: FMS total scores improved across repeated assessments, whereas the global Back-Check score showed no significant longitudinal change. Component-level and imbalance analyses indicated reductions in adductor–abductor imbalance, and better FMS performance was moderately associated with lower adductor–abductor imbalance. Conclusions: Functional movement quality and selected muscle imbalance indicators demonstrated favorable longitudinal changes during the physiotherapy-based strengthening programme. These findings suggest that physiotherapy-oriented strengthening and movement-control exercises may contribute to improvements in functional movement quality and selected muscle balance indicators in adolescent male soccer players. However, the small repeated-measures subsamples and observational study design limit causal interpretation and generalizability. Full article

This study explores how altruistic tendencies translate into altruistic behavior during evacuation and investigates the dynamic roles of altruistic intent and competitive orientations. A total of 127 adults in a lifelong education program participated in a routine fire-drill evacuation conducted in a naturalistic setting, of whom 124 were retained for the final analyses after data screening and exclusion procedures. Situational altruistic behavior was assessed through a post-drill questionnaire, and the findings should therefore be interpreted as self-reported responses within an exercise-based evacuation context. In stepwise regression analysis, altruistic intent emerged as the strongest predictor of self-reported situational altruistic behavior. While altruistic tendency and desirable competition showed positive associations, excessive competition showed a negative association. Mediation and moderation analyses revealed that altruistic intent mediates the relationship between altruistic tendency and altruistic behavior but does not function as a moderator. In contrast, desirable competition operates as a negative moderator, weakening the influence of altruistic tendency on behavior despite its positive association in the regression analysis, while excessive competition exerts a direct negative effect on altruistic behavior. Although altruistic intent plays a key role in translating altruistic dispositions into helping behavior during evacuation, competitive pressures—whether excessive or efficiency-oriented—can constrain the expression of altruistic responses. More broadly, competition does not simply oppose altruism in evacuation contexts but reshapes how altruistic tendencies are expressed during emergency movement, highlighting the importance of managing competitive dynamics to support cooperative and life-saving behaviors.

Objectives: Karting imposes high neuromuscular demands on the forearm during dynamic steering, gripping and braking. This study examined whether a single high-velocity, low-amplitude (HVLA) manipulation of the elbow acutely modified surface EMG_RMS amplitude and EMG median frequency responses during standardized isometric forearm testing after simulated karting load, rather than EMG activity during dynamic driving itself. Methods: In this randomized, sham-controlled, within-subject trial, 15 drivers completed a single-session within-participant protocol in which one upper limb was randomly allocated to receive elbow HVLA manipulation (manipulated limb) and the contralateral limb received a standardized sham procedure (sham limb) involving therapist contact and low-grade oscillatory movement without end-range pre-tension or thrust. Drivers completed two 8 min simulated races separated by the allocated manual procedure. Surface electromyography (EMG) from four forearm muscles was collected outside the karting task during standardized laboratory-based isometric forearm contractions at baseline, after race 1, post-intervention, and after race 2. EMG was not recorded during real-time steering, braking, vibration exposure or competitive driving. The extensor carpi radialis (ECR) was specified as the principal muscle of interest because the HVLA technique pre-tensioned the common extensor origin and radial wrist extensors. The primary outcome was ECR mean EMG_RMS amplitude, expressed in µV, across the four measurement time points; the primary statistical test was the condition × time interaction. ECR maximal EMG_RMS amplitude and ECR median frequency were treated as secondary outcomes, whereas ECU, FCR, and FCU outcomes were treated as exploratory anatomical specificity outcomes. Mixed-model ANOVAs compared maximal and mean EMG amplitudes and median frequency between manipulated and sham limbs, treating limb condition and time as repeated within-participant factors. Results: For the primary outcome, ECR mean EMG_RMS amplitude showed a main effect of condition (p = 0.023) and a condition × time interaction (p < 0.001). As a secondary amplitude outcome, ECR maximal EMG_RMS amplitude showed a main effect of time (p = 0.009) and a condition × time interaction (p < 0.001), with higher post-manipulation values in the manipulated limb. No consistent limb-condition effects were found for the other muscles, and EMG median frequency showed only modest time-related changes (p = 0.031) without between-condition differences. Conclusions: A single-elbow manipulation produced short-lived, muscle-specific increases in ECR activation after simulated racing, whereas broader neuromuscular changes were not evident. These findings indicate only transient modulation of ECR surface EMG amplitude in a small sample of screened karting drivers and do not demonstrate improved recovery, neuromuscular efficiency, sport performance, or injury prevention. Because EMG was assessed during standardized isometric contractions rather than during dynamic steering, braking, vibration exposure or competitive racing, the findings should not be interpreted as direct evidence of altered neuromuscular behaviour during actual kart driving. Larger studies including force, performance, clinical, fatigue-specific and dynamic driving EMG outcomes are required. Full article

This pilot randomized controlled trial (RCT) aimed to evaluate the effect of a lumbar spine stabilization exercise program (LSSEP) in healthy adults with a sedentary lifestyle. Thirty-eight healthy Greek adults (mean age 40.53 ± 11.91 years) who had been sedentary for at least six months participated in the study. They were randomly assigned to an intervention group (n = 18) and a control group (n = 20). The intervention group followed a supervised progressive four-week LSSEP, while the control group received a booklet with ergonomic and stretching instructions (passive control). The primary outcome was the 12-Item Short Form Health Survey version 2 (SF-12v2), which measures quality of life, and secondary outcomes were the Functional Movement Screen (FMS) and the Y-Balance test (YBT), assessed before and immediately after the intervention period. A repeated-measures 2 × 2 mixed ANOVA revealed significant time × group interactions in favor of the intervention group for the mental component of quality of life and for functional movement and dynamic balance performance (p < 0.05), with moderate to large effect sizes. The LSSEP appears to improve specific aspects of quality of life and movement performance in healthy sedentary adults, with potentially clinically meaningful benefits observed even within a short four-week period. Confirmation through larger, longer-term trials is warranted. Full article

Soccer support staff operate under demanding schedules and high-performance environments while guiding players’ movement, sleep, and nutrition; however, their own lifestyle behaviours remain under-researched. This exploratory study assessed adherence to the Canadian 24-Hour Movement (24HM) guidelines and its association with diet quality (DQ) in professional and semi-professional soccer support staff. Methods: A cross-sectional survey collected data from 236 staff in the United Kingdom and Spain. Movement behaviours were measured using the Whole Day Matters Toolkit and DQ using the validated Mini-EAT questionnaire. A graded 24HM score (0–8) summed binary adherence across four general (MVPA, LPA, sedentary time, sleep) and four secondary (muscle-strengthening, sedentary interruptions, screen time, sleep–wake time) behaviours. Associations with DQ were estimated using adjusted multiple linear regression. Results: Only 7.6% of participants met all eight guidelines. Each one-point increase in the graded score was associated with 0.89-point higher DQ (95% CI 0.29–1.49, p = 0.004), with stronger associations observed for secondary behaviours (β = 1.27, p = 0.006) than for general behaviours (β = 0.38, p = 0.50). Conclusions: A graded 24HM scoring approach showed a graded association with DQ in soccer staff, with secondary movement behaviours showing a stronger association. All findings should be interpreted as exploratory and hypothesis-generating. ClinicalTrials.gov: NCT06771752. Full article

Background: Physical inactivity and sedentary behaviour are major public health concerns associated with an increased risk of non-communicable diseases, reduced quality of life, and substantial healthcare burden. In recent years, technology-based interventions, including wearable devices, mobile health applications, artificial intelligence-driven systems, and adaptive digital platforms, have been increasingly adopted to promote physical activity and reduce sedentary time in adult populations. However, the evidence remains fragmented across intervention types, behavioural targets, and population groups. The aim of this scoping review was to map the recent literature on digital interventions designed to promote active lifestyles in adults, with a specific focus on their reported impact on physical activity promotion and sedentary behaviour reduction. Methods: This scoping review was conducted in accordance with the PRISMA-ScR guidelines. A literature search was performed in PubMed and Scopus using a predefined search strategy combining terms related to digital technologies, physical activity, sedentary behaviour, and adult populations. Studies published in English between 2022 and 2026 were considered. After removal of duplicates and screening of titles and abstracts, full texts were assessed according to predefined eligibility criteria. Data were charted descriptively and synthesised narratively to identify the main intervention models and emerging research trends. Results: The search identified 887 records, of which 35 studies were included in the final synthesis. The literature included was grouped into four broad categories: wearable devices and mHealth tools for monitoring and goal-setting; adaptive interventions based on Just-In-Time Adaptive Interventions, artificial intelligence, and gamification; advanced technologies such as Internet of Things systems and exoskeleton-based approaches; and hybrid interventions combining digital tools with human support or environmental modifications. Overall, technology-based interventions were generally associated with increases in step count, moderate-to-vigorous physical activity, and adherence to movement-related behaviours. In contrast, their effectiveness in reducing sedentary behaviour was less consistent and appeared to depend more strongly on context-sensitive prompting, posture-focused strategies, and multicomponent or hybrid intervention models. Conclusions: Digital health interventions represent a promising strategy for promoting physical activity in adults, but their impact on sedentary behaviour reduction remains more limited and heterogeneous. The findings suggest that simply increasing exercise is not sufficient to address prolonged sitting and that more tailored, adaptive, and context-aware approaches are needed. Future research should prioritise methodological standardisation, longer follow-up periods, and interventions specifically designed to interrupt sedentary time across different adult populations.

School physical education (PE) has often relied on linear progressions in which teachers demonstrate, pupils practise prescribed techniques, and achievement is judged through visible reproduction of preferred movement forms. Non-linear pedagogy (NLP) and the constraints-led approach (CLA) offer an alternative ecological-dynamics rationale for supporting pupils’ integral development, including motor competence, adaptable movement capability, and dispositions for lifelong physical activity and physical literacy. However, existing review work has not sufficiently explained why principled NLP/CLA designs remain unevenly enacted across ordinary school PE systems. We conducted a theory-informed interpretive synthesis drawing on critical interpretive synthesis and thematic synthesis. A structured English-language search of ERIC, SPORTDiscus, Scopus, and Google Scholar (2010–2025) was combined with title-and-abstract screening, full-text assessment, backward and forward citation chaining, and purposive retention of foundational or Singapore-context records, and reporting was strengthened through PRISMA-like transparency aids adapted to interpretive synthesis. The final coded corpus comprised 36 included sources: 9 empirical studies, 3 reviews, 9 conceptual or practitioner texts, 6 theoretical or critical sources, 4 review-method papers, and 5 Singapore policy, context, or professional-learning documents used as an illustrative policy lens. Through iterative coding, descriptive theme development, and analytical integration, we identified six coherence domains shaping enactment: teacher beliefs and knowledge; curriculum and lesson structure; assessment and accountability; systemic and resource constraints; professional development ecosystems; and stakeholder and cultural factors. These domains informed a Systemic Coherence Framework spanning micro, meso, and macro levels. The synthesis suggests that assessment coherence may be a high-leverage condition because it links curriculum legitimacy, reporting, and teacher defensibility, but its comparative influence across domains remains a hypothesis for future empirical testing. The framework is offered as an analytic heuristic rather than a prescriptive model and is intended to help researchers, teacher educators, school leaders, and policy actors diagnose where curriculum intent, assessment language, professional learning, and organisational routines support or inhibit ecologically informed practice.

Hybrid quantum-classical learning pipelines combine conventional accelerators, quantum runtimes, and quantum processing units (QPUs), creating scheduling, memory, isolation, encoding, and deployment challenges that are not captured by application-level quantum machine learning surveys alone. This paper presents a systematic review of runtime and systems mechanisms for hybrid quantum-classical workloads, with medical imaging used as a translation lens rather than as an exclusive inclusion boundary. Following a PRISMA-aligned review process, we screened 364 records and synthesized 40 studies published between 2020 and 2025. Each study was coded by systems layer, application grounding, noisy-label relevance, and evaluation maturity. The coding shows that the corpus combines direct medical evidence with broader transferable systems evidence: 8 studies directly evaluated medical data, 12 were medically motivated, and 20 were generic systems studies. Across the corpus, the strongest support concerns hybrid orchestration, qubit/resource allocation, classical–quantum data movement, and container-based reproducibility, whereas evidence remains limited for realistic clinical operation, end-to-end remote-QPU workflows, multi-tenant isolation, and noisy-label retraining loops. We contribute an evidence map, a direct/indirect/interpretive evidence distinction, and cross-layer design guidelines for future hybrid quantum-classical imaging pipelines in regulated settings.

Background: Chronic pain affects approximately 30% of older adults and is strongly associated with social isolation and loneliness, which impact an estimated 25% of the global older adult population. A substantial proportion of chronic pain in this population is classified as primary chronic pain (non-specific), characterized by persistent pain with no underlying disease or structural damage. Pharmacotherapy has limited efficacy in treating primary chronic pain and presents significant polypharmacy risks, highlighting a critical need for sustainable, non-pharmacologic interventions. Among these, Tai Chi has emerged as a promising multimodal therapy, it is a mind–body exercise that integrates gentle movement and focused breathing with social engagement, offering participants both physical relief and opportunities for meaningful human connection. Gentle movement for flexibility, balance, and strength, combined with deep breathing may also improve self-reported symptoms of chronic pain, in addition to inflammatory biomarkers such as CRP, IL-6 and TNFα. The purpose of this narrative review is to investigate the literature on Tai Chi as a method for promoting socialization and reducing self-rated chronic pain among community-dwelling, socially isolated older adults. Methods: Following librarian-assisted concept map development, we searched six electronic databases (PubMed, CINAHL, Scopus, Cochrane, ProQuest, and PsycINFO) for studies published between January 2016 and February 2026. Search strings included terms for “older adults,” “chronic pain,” “social isolation/loneliness,” and “Tai Chi.” Two reviewers independently screened results and extracted data for relevance. Results: Of the 1098 records identified, 25 studies met the inclusion criteria. Eleven studies evaluated Tai Chi or related mind–body interventions. Among these, approximately six studies reported improvements in pain-related outcomes, while five studies reported improvements in loneliness or social isolation. However, only two to three studies simultaneously evaluated both chronic pain and social isolation/loneliness outcomes within Tai Chi interventions. Overall, most studies supported Tai Chi as a safe and potentially effective intervention for older adults, with evidence suggesting benefits for both pain and social well-being. However, the limited number of studies examining combined outcomes restricts conclusions regarding the integrated effects of Tai Chi on chronic pain and social isolation. Discussion: Tai Chi is a safe, inexpensive behavioral strategy for improving social connectedness and reducing self-rated chronic pain among older adults. However, the evidence base remains fragmented, as pain and social isolation are rarely assessed together within the same trial. Future research should address this gap by considering both social isolation and chronic pain in the same study, with more standardized Tai Chi forms as the single independent variable. Full article
