The present study aims to analyze the influence of the Sport Education (SE)/Teaching for understanding (TGfU) hybrid unit on enjoyment, perceived competence, intention to be physically active, skill execution, decision making, performance and game involvement. A short-term (12-lesson) pre-test/post-test quasi-experimental design was conducted in two groups: control (technical approach: 70 students; age = 14.43 ± 0.693; n = 32 female) and experimental (hybrid unit SE–TGfU: 67 students; age = 13.91 ± 0.900; n = 30 female). The coding instrument was based on the Game performance Assessment Instrument. The Enjoyment and Perceived Competence Scale and the Measure of Intentionality to be Physically Active questionnaire were also used. The results of pairwise comparisons between the groups showed higher post-test scores for most dependent variables for boys and girls using the hybrid SE/TGfU unit. Lower post-test scores were found in pairwise comparisons for several dependent variables in both boys and girls. The present study showed that the application of hybrid models SE/TGfU could increase and help facilitate students’ game involvement and game performance, enjoyment, perceived competence and intention to be physically active, in both boys and girls. In future studies, it would be necessary to analyze psychological variables in the educational context for a deeper assessment.

Interventions based on improving athletes’ adaptive capacity to game environment conditions have been widely developed in sports science. The objective of this study was to systematically review the scientific literature on interventions and applications, from an ecological perspective, for the tactical performance of volleyball players. A systematic search was conducted in five electronic scientific databases in accordance with PRISMA guidelines: Web of Science (WOS), PubMed (Medline), Scopus, SportDiscus and Google Scholar. A total of eight studies met the inclusion criteria, all published after 2014. The risk of bias and main characteristics of the articles in different contexts were assessed. Particular attention was paid to recording data related to the characteristics of manipulation or the timing of the intervention. The results showed that these approaches influenced tactical variables in volleyball game situations. In this sense, short-session interventions with small-sided games and modifications of structural elements aid athletes’ self-regulation in different environments. Furthermore, results show that this approach allows for improvements in individual and collective tactical behavior. Based on the data analyzed, we recommend the use of ecological tasks, based on representative and modified practices that promote player adaptation, as a methodological tool in the volleyball training process.

Background: Physical activity (PA) provides significant health benefits, yet inactivity remains high in Spain, especially among adolescents and increasingly in children. Identifying barriers to PA is essential, but available tools are mainly designed for adolescents. This study aimed to adapt the “Brief Scale of Perceived Barriers to Physical Activity” for Spanish schoolchildren aged 6–12 and examine its validity and reliability. Methods: The “Brief Scale of Perceived Barriers to Physical Activity for Children” was linguistically and culturally adapted. Comprehension was assessed through cognitive interviews, and reliability was examined via a test–retest procedure with 137 Spanish schoolchildren. Several analyses were conducted, including confirmatory factor analysis (CFA) to assess the factor structure, along with reliability metrics: Cronbach’s alpha (α) for internal consistency and the intraclass correlation coefficient (ICC) for test–retest reliability. Results: CFA confirmed a four-factor structure (self-concept, motivation–interest, social support, and task incompatibility) in a sample of 137 with excellent fit indices (χ²/df = 1.394, RMSEA = 0.054, CFI = 0.976, TLI = 0.966). Internal consistency ranged from good to excellent (α = 0.831–0.979). Temporal stability was substantial to near perfect (ICC = 0.708–0.979). Measurement error was low for all items and the total score (SEM% = 6.1–37.2; MDC% = 17.0–103.0), demonstrating accuracy. Conclusions: The “Brief Scale of Perceived Barriers to Physical Activity for Children” was proven to be a reliable and valid tool for assessing perceived barriers to PA in Spanish children. It offers developmentally appropriate insights that can guide strategies to enhance supportive environments and promote long-term active behaviours. As part of the social domain, it contributes to the Spanish Physical Literacy Assessment for Children (SPLA-C) model, the first physical literacy (PL) assessment instrument developed in Spain.

Constraint manipulation within representative practice environments may shape players’ behavioral organization. This study examined pre–post changes in blocking behavior following a participation-rule manipulation designed according to the Constraints-Led Approach (CLA) to increase the functional responsibility of the wing blocker during attacks from the outside zones and explored whether these changes differed according to competitive level. Forty-six female U18 volleyball players (16.59 ± 0.88 years) from four Spanish clubs participated in three 6 vs. 6 game situations: pre-manipulation, manipulation, in which the middle blocker was prevented from assisting the wing blocker against attacks from the outside zones, and post-manipulation. Block–ball contact increased overall (Holm-adjusted p < 0.003, Cramer’s V = 0.19), and the distribution of functional outcomes also changed overall (Holm-adjusted p = 0.012, V = 0.18). Decision-making appropriateness showed a significant overall association (Holm-adjusted p = 0.048, V = 0.09). Exploratory within-division analyses showed category-specific changes in functional outcomes. Findings indicate short-term pre–post changes in some blocking dimensions, with small effect sizes. The manipulation may provide a useful task-design strategy for emphasizing wing-blocker responsibility, although further controlled research is required.

Background/Objectives: Informal caregivers of older adults are a high-burden population for psychological problems, yet evidence on the relationship between physical activity (PA) and mental health in this population is still limited. The aim of this work is to examine the association between PA status and self-reported mental health indicators (psychological distress and the number of poor mental health days) among caregivers of older adults. Methods: This cross-sectional study used data from the 2023 Behavioral Risk Factor Surveillance System (BRFSS) caregiver module. The analytical sample included 1785 informal caregivers of older adults whose care recipients’ main condition was old age/infirmity/frailty or Alzheimer’s disease, dementia, or another cognitive impairment disorder. Physical activity was classified into three groups: meeting both aerobic and muscle-strengthening recommendations, reporting some PA but not meeting both recommendations, and being inactive. The self-reported mental health indicators were psychological distress (≥14 poor mental health days in the past 30 days) and the number of poor mental health days. Survey-weighted logistic regression and quasi-Poisson regression models were fitted, adjusting for sociodemographic, health-related, and caregiving-related covariates. Results: The weighted prevalence of psychological distress was 18.8%, and the mean of poor mental health days was 5.99 days in the previous 30 days. The weighted prevalence of psychological distress was 16.3% among caregivers meeting both recommendations, 18.2% among those reporting some PA, and 23.2% among inactive caregivers; however, differences across PA groups were not statistically significant. The weighted mean number of poor mental health days was 5.5, 6.2, and 6.1 days, respectively, with no significant differences across PA groups. In adjusted logistic regression models, physically inactive caregivers had higher odds of psychological distress than those meeting both activity recommendations (OR = 3.10, 95% CI: 1.58–6.09; p = 0.001). In adjusted quasi-Poisson models, physically inactive caregivers also reported more poor mental health days (RR = 1.51, 95% CI: 1.08–2.10; p = 0.016) compared to those who met both recommendations. No significant differences were observed for caregivers who met only aerobic recommendations or only muscle-strengthening recommendations, or had insufficient physical activity relative to the reference group. Conclusions: In this survey-weighted BRFSS caregiver-module sample from participating US jurisdictions, physical inactivity was associated with poorer self-reported mental health indicators among caregivers of older adults. These findings suggest that physical inactivity may help identify caregivers at higher risk of poorer self-reported mental health, although longitudinal and intervention studies are needed to clarify directionality and causality.
