The article explores Middle school represents a transition period of growing independence, onset of puberty, changing self-image, increasing desire for peer support, and establishment of eating and exercise habits (Mizelle & Irvin, 2000; Muscarà et al., 2018; Neumark-Sztainer et al., 2010. In this transition, adolescents may become susceptible to social anxiety, body dissatisfaction, loneliness, and depression due to weight-related teasing/bullying.

It is important to assess implementation of active learning interventions to maximize their impact. Implementation quality, or how well one engages program participants, has been less studied than other implementation components (e.g., dose, fidelity). This cross-sectional, exploratory study examined associations between teacher engagement behaviors, quality of teacher engagement (i.e., teacher feedback), and student physical activity outcomes during active classroom lessons. This study used data from the Texas Initiatives for Children's Activity and Nutrition (I-CAN!) randomized controlled trial. Fixed effects regressions investigated the impact of teacher engagement behaviors on student physical activity outcomes. Bivariate correlations examined associations between teacher feedback and student physical activity outcomes. A latent profile analysis explored whether there were subsets of teachers with similar feedback profiles. The final analytic sample included 82 teachers. Teacher-directed changes and teacher participation in physical activity were each associated with higher ratings for how many and how often children were active during lessons. Teacher participation in physical activity was also significantly related to higher ratings for student physical activity intensity (all p <.05). Physical Activity Reinforcement and Technical Instruction feedback were positively associated with activity intensity (r = −.20, p <.05 and r =.34, p <.01, respectively). Technical Instruction feedback was positively associated with how many (r =.25, p <.01) and how often (r =.41, p <.01) students were active during lessons. Negative feedback was negatively associated with how often (r = −.25, p <.05) students were active and activity intensity (r = −.25, p <.05). Game Instruction was negatively related to how often students were active (r = -.23, p <.05). All teachers were represented by high levels of Game Instruction and Classroom Management feedback, moderate levels of Content Reinforcement and Content Instruction feedback, and low levels of Negative, Technical Instruction, and Physical Activity Reinforcement feedback. These data did not indicate the existence of multiple feedback profiles. Findings suggest that teacher engagement and feedback to students during active lessons can promote student physical activity. Teachers are primarily responsible for implementing school-based interventions, so it is critical to develop strategies that increase their ability to implement them successfully. Opportunities to maximize intervention delivery, such as co-designing with teachers, should be utilized when designing school-based, physical activity interventions. [ABSTRACT FROM AUTHOR]

Shortened or missed dialysis treatments are directly associated with increased hospitalization and mortality rates among end-stage renal disease (ESRD) patients. The purpose of this study was to investigate the differences in treatment adherence according to the number of years on dialysis and demographic factors such as age, annual income, living status, and sex, with respect to the numbers of dialysis treatments shortened by ≥10 min and missed dialysis treatments among patients undergoing in-center hemodialysis. This study used a quantitative and nonexperimental research design to investigate the differences in adherence. Data were collected from 412 in-center hemodialysis patients through patient surveys and from the participants' medical records. Dialysis patients aged ≥60 years were found to be more adherent than those aged 18–59 years, with a statistically significant difference between the groups (p =.01, each for shortened and missed treatments). Patients whose annual income was >200% of the federal poverty level were also more adherent than those who reported less income, with a statistically significant difference between the groups (p =.01, each for shortened and missed treatments). Future studies should focus on addressing adherence by incorporating more adherence factors and different treatment modalities for ESRD. [ABSTRACT FROM AUTHOR]

To validate the modified System for Observing Fitness Instruction Time to measure teacher practices related to physical activity promotion (SOFIT+) in physical education (PE) amongst 5–6-year-old-children. Participants (n = 162, 53% female, 6.0 ± 0.3 yrs) were recruited from 9 schools. Video-recordings of 45 PE lessons from 9 teachers/coaches were coded using a modified SOFIT+. Accelerometers measured children's moderate-to-vigorous physical activity (MVPA). Validity was assessed via multinomial regression measuring the relationship of both SOFIT+ index score and individual teaching practices with children's MVPA. Inter-rater reliability was examined. A 1 unit increase in the SOFIT+ index was associated with increased likelihood to engage in 10–19 sec, 20–29 sec and 30–40 sec of MVPA, compared to 0–10 sec. Most of the observed teaching practices were significantly related to children's MVPA. Inter-rater percentage of agreement ranged between 88.8% and 99.7%. SOFIT+ is a valid and reliable assessment of teaching practices related to MVPA promotion in PE amongst 5–6-year-old-children. [ABSTRACT FROM AUTHOR]

Problem-based learning is an experiential and student-centred learning method to practice important skills like querying, critical thinking, and collaboration through pair and group work. The study is aimed at comparing the effectiveness of problem-based learning (PBL) and traditional teaching (TT) methods in improving acquisition of radiographic interpretation skills among dental students. Clinical trials (randomized and nonrandomized) were conducted with the help of dental students studying oral radiology using PBL and TT methods and assessing radiographic interpretation skills, knowledge scores, and satisfaction level as outcomes. Articles published from PubMed/MEDLINE, DOAJ, Cochrane Central Register of Controlled Trials, and Web of Science were searched. The quality of the studies was evaluated using the Cochrane Collaboration Tool, the MINORS Checklist, and the Risk of Bias in Nonrandomized Studies of Interventions (ROBIN-I) tool. Meta-analysis was done using Review Manager 5.3. There were twenty-four articles for qualitative synthesis and 13 for meta-analysis. The cumulative mean difference was found to be 0.54 (0.18, 0.90), 4.15 (-0.35, 8.65), and -0.14 (-0.36, 0.08) for radiographic interpretation skills, knowledge scores, and satisfaction level, respectively, showing significant difference favouring PBL as compared to TT except for satisfaction level which favoured the TT group. To understand the long-term effectiveness of PBL over TT methods in oral radiology among dental students, well-designed long-term randomized controlled trials are needed. [ABSTRACT FROM AUTHOR]

Physical activity (PA) promotion for children with disabilities tends to be less of a priority in physical education teacher education programs when compared with a focus on motor and sport-specific skills and strategies. As a result, physical education teachers tend to have less competence in promoting PA of students with disabilities, leaving students with disabilities to feel disconnected from the physical education class. Students with a disability subsequently are likely not to benefit from physical education in terms of PA participation. This paper aims to provide guidelines and strategies to promote PA in inclusive physical education settings. In this paper, we define PA and provide specific strategies grounded in self-determination theory and the socioecological model to promote PA during physical education class. Strategies proposed include (a) selection of disability sport and instructional models, (b) grouping practices to facilitate relatedness, skill development, and participation, (c) approaches to increase choice and encourage decision making, and (d) use of goal setting and self-evaluation.

Objective: To compare cardiovascular risk and cardiorespiratory capacity in schoolchildren from a region in the extreme south of Chile according to nutritional status and muscular strength. Methods: An analytical cross-sectional study was performed on a sample of 594 schoolchildren from 5th to 8th grade in the extreme south of Chile. Based on body mass index and lower limb muscle strength, participants were divided into four groups: high strength-normal weight, high strength-overweight/obese, low strength-normal weight, and low strength-overweight/obese. Then, waist-to-height ratio and cardiorespiratory capacity, measured with the 20 m shuttle run test, were assessed to determine their cardiovascular risk, comparing the four groups. Results: The overweight/obese group with high muscular strength presented better indicators in anthropometric variables (waist circumference and waist-to-height ratio) than their peers with low muscular strength. Additionally, the overweight/obese group with low muscular strength presented a lower cardiorespiratory capacity than their peers with high muscular strength. Both results were observed in boys and girls. Conclusion: The results of this study suggest that overweight/obese schoolchildren with high muscle strength present healthier anthropometric indicators and greater cardiorespiratory capacity than their peers with low muscle strength. These results confirm the relevance of measuring muscle strength in schoolchildren and its usefulness to assess functionality. These results encourage the scientific community to continue studying the role that muscle strength plays in modulating the effects of overweight and obesity on respiratory and cardiovascular conditions in childhood [ABSTRACT FROM AUTHOR]

Interventions to increase physical activity in children have adopted broad approaches and achieved varying success. There is a need to adopt approaches underpinned with a theoretical basis. Accordingly, the aim here was to implement and evaluate a 12-week intervention designed using the concepts of the COM-B model to determine the effect this has on physical activity levels. One hundred and forty-seven school-age children (mean age 8.9 ± 1.3 years) took part in a 12-week program delivered in a school setting. Topics included physical activity, healthy eating, sleep quality and reducing screen time/sedentary activities when not in school. A sample of participants wore a wrist-worn accelerometer for seven days pre-and post-intervention (N = 11). The physical activity frequency was unchanged (2.9 ± 1.0 AU) when compared with post-intervention values (3.1 ± 0.8 AU, mean increase 6.8 ± 3.7%, p > 0.05). Changes were observed in the daily consumption of fruit and vegetables (pre-intervention 44.6% vs. post-intervention 60.2%, p < 0.05). Sedentary time, light activity, moderate activity and vigorous activity were unchanged post-intervention (p > 0.05). There is a need to adopt a broader approach that incorporates a theoretical basis and considers the complex ways by which physical activity behaviours are influenced. [ABSTRACT FROM AUTHOR]

While research in specific academic disciplines has individually advanced knowledge and practice for promoting multiple aspects of health and well-being in children and adolescents, still missing is an understanding of the interconnectedness of many critical aspects of development and how to intentionally weave these factors to advance a more holistic approach. The need for a more holistic and inclusive approach to child and adolescent development is increasingly evident to promote long-term health and well-being as the overall percentage of children, adolescents, and adults who suffer from mental health disorders is increasing. To address this issue, our authorship team consists of researchers in the areas of developmental psychology, neuroscience, motor development, exercise science, and mental health. The collective ideas outlined in this paper are aligned to address the need to remove disciplinary-specific boundaries and elucidate synergistic linkages across multiple research domains that support holistic development and lifespan health and wellness. We propose a conceptual framework that comprehensively addresses the integration of physical, cognitive, psychological, social, and emotional domains of child and adolescent development. In addition, we also provide a holistic preventative approach that is aligned with a contemporary intervention structure (i.e., Multi-tiered Systems of Support) to promote, from a developmental perspective, positive trajectories of health and well-being across childhood and adolescence., (© 2023.

The effect of an acute bout of physical activity on academic performance in school-based settings is under researched. The purpose of this study was to examine associations between a single, vigorous (70–85%) bout of physical activity completed during physical education on standardized mathematics test performance among 72, eighth grade students at a school in the Southwestern United States. Students received both a physical activity and nonactive condition, in a repeated measures design. Academic performance measures were collected at 30 and 45-minutes post condition. It was hypothesized that students would have greater gains in mathematics test scores post physical activity condition compared with post nonactive condition. Results reported students achieved 11–22% higher math scores at 30 minutes post physical activity condition compared with other time points (45 minutes post PA, 30 and 45 minutes post sedentary) (F(1, 68) = 14.42, p < .001, d = .90). Findings suggest that physical activity may facilitate academic performance in math. [ABSTRACT FROM AUTHOR]

Recommended approaches to promoting children’s physical activity through schools call for physical education teachers to serve as champions for, and leaders of, Comprehensive School Physical Activity Programs (CSPAPs). Little evidence, however, exists to suggest that physical education teachers are ideally prepared or supported to assume CSPAP leadership roles. The purpose of this article is to consider expectations that must be met for physical education teachers to serve as central protagonists in CSPAP implementation efforts, and to propose a conceptual model aimed at increasing both effectiveness and sustainability of CSPAPs through key external-internal partnerships. Specifically, community-based participatory research, communities of practice, and service-learning are presented as possible strategies to expand the support system for growing and sustaining CSPAPs. In sum, this article offers some reasons for rethinking current recommendations for CSPAP implementation. [ABSTRACT FROM PUBLISHER]

This exploratory study examined the effect of participation in a 6-week physical activity-based summer day camp (Camp PAL) that incorporates life skills promoted in the Teaching Personal & Social Responsibility model (TPSR) on physical activity and psychosocial outcomes of diverse urban youth. Specifically, we assessed children's daily physical activity levels, self-perceptions of competence in their social life, physical appearance, and global self-worth, and personal and interpersonal developmental skills. In addition, observational data were collected to assess the fidelity of the Camp PAL program in delivering elements of the TPSR model. The results showed that participation in the Camp PAL program helped children achieve substantial daily physical activity levels—which frequently decrease during the summer months when children are not participating in school physical education, especially for marginalized youth. The results also showed that all campers felt their program participation benefited them in terms of their social lives, physical appearance, and global self-worth as well as their development of personal/social, goal setting, and initiative skills. Campers of color reported benefitting the most in a number of these psychosocial domains. Observational data analysis supported the effectiveness of the camp program in delivering elements of the TPSR model. The results provide initial evidence that summer camp programs, like Camp PAL, may help diverse populations of urban children maintain adequate daily physical activity levels while simultaneously promoting their broader social welfare.

Little is known of how reallocations of time spent in different movement behaviors during preschool might relate to preschoolers' fundamental movement skills (FMS), a key predictor of later physical activity (PA). Thus, the aim of this study was to examine (a) whether preschoolers' school-time movement was associated with their FMS and (b) the effects on FMS of reallocating time between PA and sedentary behavior (SB). This was a cross-sectional study, using intervention data with Brazilian low-income preschoolers. We observed Brazilian preschoolers of both sexes (M age = 4.5, SD = 0.8 years-old; 101boys) over 10 hours of school-time and objectively assessed their PA and SB with Actigraph wGT3X and their FMS with the Test of Gross Motor Development – Second Edition. We explored the associations between school-time movement behaviors and FMS and between reallocated school-time movement behaviors and FES using compositional analysis in R (version 1.40-1), robCompositions (version 0.92-7), and lmtest (version 0.9-35) packages. This isotemporal reallocation showed that, for manipulative skills, reallocating time (5, 10, and 15 minutes, respectively) from light PA to SB was associated with increasing skill (0.14, 0.28, and 0.42 FMS units), raising questions as to whether fine motor activity occurred during SB. Thus, school-time movement significantly predicted FMS, with a modest increase in SB, at the expense of light PA eliciting improved manipulative skills. [ABSTRACT FROM AUTHOR]

This research aimed to analyze the current trends in the digital transformation of educational institutions. The investigation lasted from November 2019 to May 2020 and was based on three higher educational institutions (HEIs) in the Russian Federation: Belgorod State University, Moscow State Institute of International Relations, and Kutafin Moscow State Law University. The number of respondents enrolled was 420 people. In an attempt to bring together views and experiences of different actors of the educational sector, three individual online surveys were conducted among administrative staff, teachers, and students of mentioned educational institutions. All respondents were provided with questionnaires aimed at identifying current trends in educational paradigm transformation and studying the extent to which digital strategies are applied in the process of HEIs' development. The detailed analysis of survey outcomes allowed indicating positive and negative trends in digitalization of educational processes from the perspective of university administrative staff, teachers, and students. Positive trends were: ensuring the availability of higher education through the implementation of full-fledged distance learning courses; enhancing the students' experience through the introduction of innovative teaching methods; providing open access to educational resources and research results; opportunity to participate in global "open science" initiatives; and reduction of higher education cost to ensure its accessibility and mass scale. The barriers to the digital transformation of the educational sphere were: lack of funds for the implementation of a comprehensive digital transformation strategy; resistance to changes on the part of the staff; and a low level of confidence in technological solutions used in teaching practice. As a result, the conducted investigation uncovered the essence of digital transformation in the institutional structures of the higher education sector. However, given that digitalization is a complex process affecting most spheres of socio-economic interaction, consideration of only positive and negative digital transformation trends is insufficient to thoroughly analyze global digital shifts and the formation of national vectors for digital society development.

Purpose: Physical education policies provide guidance and accountability to develop quality programs that increase physical literacy. The purpose of this study was to conduct a systematic review of physical education policy research to explore its effects on the school environment and programming as an essential component of physical education. Methods: Using the PRISMA guidelines of identify, screen, determine eligibility, and include, studies were extracted from four different databases, using search terms related to the essential physical education component of policy and environment. Of the 225 publications identified, 42 studies met the inclusion criteria for this investigation. Each paper was coded, and emergent themes were identified. Results: The policy research was predominantly descriptive and focused on: (a) minutes in physical education (83%), (b) moderate to vigorous physical activity (MVPA; 31%), (c) certified/qualified teachers (24%), (d) exemptions (17%), and (e) student-teacher ratio (12%). Emergent themes of adherence, policy strength, and implementation accountability were identified as influential physical education policy aspects. Conclusions: Policy research over the last 20 years was focused on the regulatory mandate of time. Policy research did not directly address disciplinary process variables of learning activities or outcomes of physical education. The effects of policy exemptions and class size were underrepresented. Themes may explain the lack of reporting student performance as the primary outcome. Further research is needed to examine the downstream effects of physical education policy and determine whether well-written policies increase the number of physically literate individuals.

Purpose: The purpose of this article is to provide a summary of contemporary empirical evidence supporting the need for the essential components of physical education as the minimum threshold of quality. The collective findings from a series of systematic reviews conducted through university, community, and the Centers for Disease Control and Prevention (CDC) collaborations are timely and warranted given the current trends in physical inactivity and obesity among youth and emerging adults. Methods: Faculty and students from five doctoral physical education teacher education programs (D-PETE) conducted distinct but interrelated systematic reviews of the Essential Components of Physical Education—policy and environment, curriculum, instruction, and assessment. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (identify, screen, determine eligibility, and include), relevant studies were extracted from six databases. Only peer-reviewed publications related to each essential component were examined. Full papers were included in the final analysis if they were published between January 2000 and May 1, 2020, had a primary outcome related to PreK–12 physical education, and were empirical and original investigations. Results: Each essential component, in part, was empirically supported. Some actionable criteria for a given component were underdeveloped and in need of more empirical research to advance our understanding of policy and environment, curriculum, instruction, and assessment in authentic contexts. Conclusions: Implications for the essential components of physical education and future directions for K–12 physical education, teacher education, and research are outlined in this article.

Background: The long‐term closing of schools and home‐quarantine during the COVID‐19 pandemic cause negative effects on the physical and mental health of young people. Studies evaluating the mental health of adolescents during the pandemic are limited in the literature. Aim: In our study, it was aimed to determine the results of home‐quarantine measures taken for adolescents during the pandemic and the affecting factors. Method: This study was conducted as an online cross‐sectional self‐report questionnaire and included children aged between 12 and 18 years. The data were obtained from the children of volunteer families via Facebook family groups, and Google Forms questionnaires sent by the child psychiatry clinic to their smartphones. Sociodemographic form, State‐Trait anxiety scale, and UCLA loneliness survey were used as data collection tools. Results: We examined the data of 745 adolescents. The average age of the study group was 16.83 ± 1.66 years, and 69.5% were females. It was determined that 88.2% of the adolescents followed the developments in the COVID‐19 process and obtained most information from the television. State anxiety was related to "Former psychiatric referral" by 4.39‐fold, "Having a COVID positive patient in the family or your surroundings" by 3.81‐fold, and "The most common medium for obtaining COVID‐related information" by 2.41‐fold. Conclusions: Closure of schools and home‐quarantine during pandemic causes anxiety and loneliness in young people. The identification of risky groups helps to properly support these individuals by various social connections, including healthcare professionals, families, and schools. [ABSTRACT FROM AUTHOR]

When hydrogels are designed for biological applications, the mechanical properties are carefully chosen to match their precise application. However, traditional methodologies of mechanical characterization (simple shear or compression/extension) commonly ignore the multiaxiality of in vivo deformations. A recent study highlights that biopolymers and tissue indeed show a complex response to combined uniaxial and shear strains. In this study a synthetic yet biomimetic fibrous hydrogel is used, which is based on polyisocyanides and forms a self-assembled network of branched semiflexible chains, similar in architecture networks of structural biopolymers like actin, collagen, and fibrin. Its synthetic nature allows to decouple key parameters of these networks and individually understand their impact on the mechanical response under multiaxial deformation. Experimentally, it is found that the persistence length is a key parameter of biological networks, which tunes softening of gels under compression: The stiffer the polymer, the more the network softens in compression. This study provides insights into tissue behavior that likely is only obtainable from synthetic model systems and is able to direct further the design of new synthetic biomimetic soft materials that are in high demand as tunable bio-free extracellular matrix materials.

Background: The effectiveness of physical activity (PA) as an intervention against anxiety disorders and depression is undeniable in clinical psychology. Therefore, the question arose whether these effects also occur when a fear stimulus, like the COVID-19 pandemic, affects otherwise healthy adolescents. Boredom is closely linked to symptoms of fear and anxiety, but the connection between PA, boredom and fear is partly unclear. Methods: A cross-sectional online study was conducted that involved 122 students. Participants were 13–19 years old (M age = 15.83, SD = 1.73). The survey was available online from April 27th to May 3rd, 2020. At this time, schools in Germany had already been closed for 6 weeks. A self-report questionnaire was used to measure physical activity, boredom, and fear of COVID-19. A multiple linear regression model was conducted. Results: The reported fear of COVID-19 significantly correlates with total PA, quantity of strenuous PA, and boredom. Furthermore, a significant regression equation was found. The variables boredom, PA, and age contribute significantly to predicting the fear of COVID-19 [ R 2 = 0.127, F (3,118) = 6.876, p < 0.000], among adolescents. Conclusion: Our results indicate that there is an association between PA, boredom and the quarantine experience of adolescents. Students who were physically more active, especially with strenuous intensity, did not feel bored and showed less fear of COVID-19. [ABSTRACT FROM AUTHOR]

The health status of children in the United States varies by racial and ethnic, shaped by an interrelated set of systems that disadvantage children of color in the United States. In this article, we argue for a broad view of resilience, in both research and policy, that views resilience not just as a property of individuals but also as a characteristic of social contexts and policies. Accordingly, we describe the empirical evidence for policies and contexts as factors that can improve health among children and families that are deprived of equal opportunities and resources due to structural racism. We discuss the evidence and opportunities for policies and interventions across a variety of societal systems, including programs to promote economic and food security, early education, health care, and the neighborhood and community context. Based on this evidence and other research on racism and resilience, we conclude by outlining some directions for future research. [ABSTRACT FROM AUTHOR]

The adoption and dissemination of evidence-based programs is predicated on multiple factors, including the degree to which key stakeholders are motivated to implement program best practices. The present study focuses on the development of indicators that capture motivations of teachers to adopt school wellness programming since personal motivations are central to achieving sustainable impacts in these settings. The study specifically describes the measurement development and validation of the Self-Regulations for Educators Questionnaire (SREQ), designed to measure educators' autonomous and controlled motivation for adopting evidence-based programming in their schools. A naturalistic design to study motivation to adopt aspects of NFL PLAY60 programming through the NFL PLAY60 FitnessGram Partnership Project was used. A total of 1,106 teachers completed the SREQ online. Internal validity was assessed through exploratory and confirmatory factor analysis, and predictive validity using structural equation modeling (SEM). The results supported the two-factor solution with separate items capturing aspects of autonomous and controlled motivation. Both factors had good internal reliability and the item-total correlation coefficients were above 0.40 for both factors. The results also supported the predictive validity as autonomous motivation positively predicted the level of overall engagement, teaching effectiveness, fitness testing reports sent home, and completion of fitness testing with students (p <.05). Controlled motivation positively predicted whether the teachers conducted fitness testing and the engagement of Play 60 Challenge (p <.05). Findings suggest that the SREQ displays a number of psychometric characteristics that make the instrument useful for examining motivation of providers to implement evidence-based best practices.

This study examined sex differences in child friendship networks relative to summer care programs and associations with self-reported physical activity (PA) across summer. Children (n = 182; mean age = 9.93 years; SD = 1.28) at two summer care programs reported PA and information about up to five people they hung around with at the program and five outside the program at the beginning and end of summer. Male children reported significantly more PA than females at both timepoints. Average PA of in-program friends was significantly associated with PA for both sexes. More studies should acknowledge access to summer care programming when assessing summertime PA. [ABSTRACT FROM AUTHOR]

Household confinement due to the rapid spread of the pandemic caused by COVID-19 has brought very significant changes, such as the forced stay-at-home of children due to the closure of schools. This has meant drastic changes in the organization of daily life and restrictions on their activities, including exercise, which could affect the quality of life of the children due to its importance. In order to study the relationship between physical activity and psychological well-being of minors, a study has been carried out with Mixed Methods Research, combining survey methodology with transversal design with qualitative methodology using discourse analysis. A total of 234 parents of minors in Spain and several Spanish-speaking countries in America participated. The instrument was a questionnaire in Google Forms, which included the Kidscreen-27 quality of life scale. The results show significant differences in both the type of physical activity and its frequency due to age, and differences in parents' perception of whether their children's physical activity levels were sufficient or not, both on the health, mood and school subscales, and in the categorization of open responses referring to concerns due to the pandemic, analyzed with the ALCESTE technique. The relationship between physical activity of children and adolescents and quality of life is clearly concluded. [ABSTRACT FROM AUTHOR]

The use of Comprehensive School Physical Activity Program (CSPAP) has been recommended to help students achieve 60-minutes of physical activity each day. Implementing a CSPAP requires planning, coordination, and ongoing oversight, but an understudied factor is how principal support influences CSPAP implementation. The purpose of this study was to evaluate the impact of principal support on CSPAP implementation. Method. Schools in the Iowa FitnessGram Initiative (n = 84), a participatory network of schools committed to supporting physical education and wellness efforts, were invited to participate in the study. Physical education teachers from 42 schools completed a survey assessing CSPAP implementation and principal support for school wellness. Descriptive statistics and correlation analyses were used to report associations between the variables. A regression analysis was conducted to evaluate the impact of principal support on CSPAP implementation. Results. Almost half of the schools were reported to be fully implementing just one CSPAP component and no school was reported to be fully implementing all five. The CSPAP component with the highest reported level of implementation was quality physical education, while the lowest level of implementation was reported for family and community engagement and staff involvement. The regression analysis identified that principal support was a significant predictor of CSPAP implementation, b = 0.55, t (37) = 3.10, p <.004. Conclusions. Principal support is associated with implementation of CSPAP initiatives. Strategies that focus on how to attain principal support for CSPAP initiatives are needed and could have a significant impact on student physical activity and health. [ABSTRACT FROM AUTHOR]

During long periods without school, children are more susceptible to unhealthy behaviors, such as an increase in sedentary behaviors, which has a negative impact on children’s motor competence (MC). The COVID-19 lockdown offered us a unique opportunity to test, in a quasi-experimental setting, the impact of lockdown movement restrictions on children’s MC. We assessed the motor competence of 114 children aged 6–9 years using the motor competence assessment. All children were tested before and after the COVID-19 lockdown. Chi-square and 2 × 2 ANOVA (sex by moment) were used to further analyze the data. Regardless of sex, motor performances in all tests (except for jumping sideways in boys) were lower when compared with performances before lockdown. There was a marked decreasing trend in children’s levels of MC, shifting from an upper to a lower quartile in different tests. The results after the lockdown were always significantly inferior to the results before lockdown in all motor tests (except jumping sideways), in the three components of MC, and in global MC. Children’s global MC score decreased by an average of 13 points in boys and 16 points in girls. The imposed movement restrictions had a negative effect on children’s motor competence development.

Studies have demonstrated that cancer cells tend to have reduced stiffness (Young's modulus) compared to their healthy counterparts. The mechanical properties of primary brain cancer cells, however, have remained largely unstudied. To investigate whether the stiffness of primary brain cancer cells decreases as malignancy increases, we used a microfluidic constriction channel device to deform healthy astrocytes and astrocytoma cells of grade II, III, and IV and measured the entry time, transit time, and elongation. Calculating cell stiffness directly from the experimental measurements is not possible. To overcome this challenge, finite element simulations of the cell entry into the constriction channel were used to train a neural network to calculate the stiffness of the analyzed cells based on their experimentally measured diameter, entry time, and elongation in the channel. Our study provides the first calculation of stiffness for grades II and III astrocytoma and is the first to apply a neural network analysis to determine cell mechanical properties from a constriction channel device. Our results suggest that the stiffness of astrocytoma cells is not well-correlated with the cell grade. Furthermore, while other non-central-nervous-system cell types typically show reduced stiffness of malignant cells, we found that most astrocytoma cell lines had increased stiffness compared to healthy astrocytes, with lower-grade astrocytoma having higher stiffness values than grade IV glioblastoma. Differences in nucleus-to-cytoplasm ratio only partly explain differences in stiffness values. Although our study does have limitations, our results do not show a strong correlation of stiffness with cell grade, suggesting that other factors may play important roles in determining the invasive capability of astrocytoma. Future studies are warranted to further elucidate the mechanical properties of astrocytoma across various pathological grades. [ABSTRACT FROM AUTHOR]

Purpose: To estimate temporal trends in broad jump performance for United States youth, a marker of muscular fitness and health. Method: Electronic databases, topical systematic reviews, and personal libraries were systematically searched for studies reporting descriptive standing broad jump data for apparently healthy United States youth (age 10--17 years). Temporal trends at the sex-age level were estimated using sample-weighted regression models associating the year of testing to mean jump performance, with national trends standardized to the year 1985 using a post-stratified population-weighting procedure. Results: Collectively, there was a small increase of 12.6 cm (95%CI: 12.5 to 12.7) or 7.9% (95%CI: 7.1 to 8.6) in 65,527 United States youth between 1911 and 1990. Increases were greater for girls (change in means [95% CI]: 17.1 cm [16.9 to 17.3]; 11.4% [10.7 to 12.2]) compared to boys (change in means [95% CI]: 8.5 cm [8.3 to 8.7]; 4.6% [3.8 to 5.4]), but did not differ between children (10--12 years) and adolescents (13--17 years). Increases in broad jump performance were not always uniform across time, with steady and progressive increases observed for boys and children, respectively, and a diminishing rate of increase observed for girls and adolescents. Conclusions: Muscular fitness is a good marker of health, so greater broad jump performance from 1911 to 1990 may reflect corresponding changes in health. Routine assessment of broad jump performance may be useful to monitor trends in health and muscular fitness of United States youth due to its practicality, scalability, and predictive utility.

Objective On March 10, 2020, the Italian Government ordered a national lockdown to limit the viral transmission of coronavirus disease 2019 infections. This study investigated how these restrictive measures have impacted sleep quality, timing, and psychological difficulties in school-age children and their mothers during the lockdown. Methods In an online survey, 299 mothers reported their sleep habits, experience of time, and psychological difficulties as well as those of their children (6–10 years old) during and, retrospectively, before the lockdown. Results During the lockdown, children showed a marked delay in sleep timing—that is, later bedtime and rise time—and a mild worsening in sleep quality. They were less prone to respect daily routines or to keep track of the passage of time. They showed increased emotional, conduct, and hyperactive symptoms, and the increase in these psychological difficulties was predicted by the change in sleep quality, boredom, and mothers' psychological difficulties. In addition, mothers showed a delayed sleep timing and worsening of sleep quality during the lockdown, in varying degrees depending on their working conditions. Mothers who kept working regularly outside their homes during lockdown reported more regular sleep patterns, whereas mothers who stopped working showed more emotional symptoms and relevant changes in their perception of time. Conclusions Overall, given the evidence of the adverse behavioral and psychological impact of home confinement and social restrictions, effective measures needed to be in place to mitigate long-term effects on children and their mothers, especially those who have had to stop working during lockdown.

This paper presents findings on physical education (PE) trainees' and teachers' attempts to design and implement authentic curricular experiences, within the constraints of a neoliberalist context. It involved adopting a principle‐based approach to promoting active lifestyles designed to align PE trainees' and teachers' health‐related philosophies and pedagogies. The promoting active lifestyles (PAL) project was framed by social cognitive theory and the social ecological model and adopted a qualitative explanatory case study approach. Participants were secondary school PE trainees and teachers involved in a University‐based Initial Teacher Education partnership in the East Midlands in England. The 32 participants were involved in professional development which included co‐constructing and implementing PAL principles in the schools in which they were employed or undertaking their placement. All participants viewed the PAL principles positively and were able to implement at least some of them. Participants experienced unanticipated benefits beyond increased physical activity such as improved pupil behaviour. Many participants described transformative and enduring changes to their health‐related philosophies and pedagogies. This low cost, flexible principle‐based approach to pedagogical change addresses calls for evidence‐based PE‐for‐health pedagogies and the development of possibilities that acknowledge the complexity of supporting physical educators to become more effective promoters of physical activity.

The article discusses the implications and effectiveness of implementing Comprehensive School Physical Activity Program (CSPAP) in physical education of students. Topics discussed include the Physical Education Teacher Education (PETE), the training of the physical education teachers, and the professional development of classroom teachers and physical educators.

High levels of physical inactivity are evident among many American children. To address this problem, providing physical activity (PA) during the school day within the CSPAP framework, is one strategy to increase children's PA. Thus, the purpose of this study was to examine the effects of a classroom-based PA program on children's PA. Two hundred and ten students from one school participated in TAKE 10! for 12 weeks. All students wore pedometers and a sample of 64 students wore accelerometers for 4 days during week 1 (baseline), week 8 (midintervention), and week 12 (end-intervention). Data were analyzed using repeated-measures ANOVA. The results showed that students' daily in-school step counts increased by 672 steps from baseline to midintervention (P < .001). Students' moderate-to-vigorous intensity PA (MVPA) increased by approximately 2 minutes from baseline to end-intervention (P < .01). In conclusion, participating in TAKE 10! helps children strive toward the goal of recommended daily MVPA. [ABSTRACT FROM AUTHOR]

The purpose of this study was to identify factors associated with Danish schoolteachers sustained use of classroom-based physical activity and to point out usable ways to support teachers in their professional practice. The study reports on data from in-depth interviews with nine teachers across grade levels and subjects. Supportive elements influencing sustained use of CBPA were: didactical skills; teacher collaboration (including sharing and co-creation of activities); and resources focusing on suitable physical activities. This study underlines that integration of classroom-based physical activity is a reflective teaching practice, and that activities are not just an addition, but something that has to make sense for the content of subjects, for the students and for the individual teacher.

Reduced physical activity (PA) and prolonged screen time (ST) negatively influence health-related quality of life (HRQoL), a protective factor against illness and mortality. Studies addressing the relationship between PA, ST, and mental health in youth are scarce, especially in times with high mental health burdens like the COVID-19 pandemic. The purpose of this examination was to investigate whether PA, ST, and HRQoL before COVID-19 predict PA, ST, and HRQoL during the COVID-19 pandemic. Participants from the Motorik-Modul Study (MoMo; N = 1711; Mage = 10.36 (SD = 4.04) years, female = 49.8%; healthy weight = 76.8%) self-reported their PA and ST as well as HRQoL both before and during COVID-19. Relationships of all variables, from before to during COVID-19, were investigated through a path prediction model. Results showed all variables during COVID-19 were predicted by the respective levels before COVID-19, independent of gender and age. Cross-lags revealed a negative influence of before COVID-19 ST on during COVID-19 PA. HRQoL before COVID-19 was positively associated with during COVID-19 PA in children younger than 10 years and females, but not in adolescents and boys. As age- and gender-independent negative influence of before COVID-19 ST on during COVID-19 PA has been detected, health policy may be advised to focus on a general reduction in ST instead of PA enhancement to ensure high PA levels.

Research on physical activity (PA) in different educational settings could elucidate which interventions promote a healthy school lifestyle in early childhood education (ECE). The aims of this study were: (a) to analyse the PA levels of preschoolers during school hours, as well as the rate of compliance with specific recommendations on total PA (TPA) and moderate-vigorous PA (MVPA); (b) to examine the role of structured movement sessions and recess time in the MVPA levels during school hours; (c) to evaluate the sociodemographic correlates of preschoolers and the school environment on MVPA behaviour during school hours. PA was evaluated with Actigraph accelerometers. Our main findings were that: (a) preschoolers engaged in very little TPA and MVPA during school hours; (b) children showed significantly higher MVPA levels on days with versus without structured movement sessions, and the contribution of the structured sessions to MVPA was significantly higher than that of recess time; (c) gender and age were associated with PA, and a high density of young children on the playground was associated with high levels of vigorous PA, whereas in the classroom, high density was associated with more sedentary behaviour. Structured PA could reduce the gap in achieving international recommendations. [ABSTRACT FROM AUTHOR]

The purposes of the study were: (1) to investigate the associations between fundamental motor skills (FMS), health-related fitness (HRF) and physical activity (PA) during middle childhood; and (2) to examine whether HRF serves as a mediator in these pathways. The participants were 342 children (156 girls; Mage = 8.40, SD = 0.50) recruited in Texas. Children's FMS (locomotor and ball skills) were assessed. School-based PA that included light, moderate, and vigorous PA was captured by accelerometers. The FITNESSGRAM battery was used to measure children's HRF, including body composition, cardiorespiratory fitness, and muscular fitness. Structural equation models were used to evaluate two proposed models (model-1 = FMS»HRF»PA; model-2 = PA»HRF»FMS). Both locomotor and ball skills were associated with all components of HRF (p < 0.01), but not PA. The SEM analyses supported associations between FMS, HRF and PA, with sound goodness-of-fit indices: (1) model-1: CFI = 0.95; RMSEA = 0.072; and (2) model-2: CFI = 0.95; RMSEA = 0.071, respectively. The relationship between FMS and PA was fully mediated by the HRF in both directions. The behavioral mechanism (e.g., maintaining appropriate levels of HRF) provides meaningful insights to understand the obesity trajectory during middle childhood. [ABSTRACT FROM AUTHOR]

Disparities in childhood obesity highlight the need for research to identify its early predictors in high-risk populations, such as low-income, Latino families. In the current study, the first of its kind in a low-income Latino sample (N = 55; Mchild age = 12.74 months, SD = 3.96), we investigated whether mothers' self-reported attachment style predicted their infants' weight-for-length (WFL; an early indicator of childhood obesity). We also explored whether observed maternal sensitivity, coded from a video-recorded semi-structured play assessment, mediated this association. We found a significant direct effect of maternal attachment style on infants' WFL z-scores (c' = −0.68, SE = 0.22, p =.004). Infants of mothers who classified themselves as secure had lower WFL z-scores than infants of insecure mothers (avoidant or anxious). Maternal sensitivity did not mediate this association, but was positively associated with infant WFL z-scores. We discuss implications of these findings for future research. [ABSTRACT FROM AUTHOR]

This study demonstrates a novel data-driven method of summarising accelerometer data to profile physical activity in three diverse groups, compared with cut-point determined moderate-to-vigorous physical activity (MVPA). GGIR was used to generate average daily acceleration, intensity gradient, time in MVPA and MX metrics (acceleration above which the most active X-minutes accumulate) from wrist-worn accelerometer data from three datasets: office-workers (OW, N = 697), women with a history of post-gestational diabetes (PGD, N = 267) and adults with ≥1 chronic disease (CD, N = 1,325). Average acceleration and MVPA were lower in CD, but not PGD, relative to OW (−5.2 mg and −30.7 minutes, respectively, P < 0.001). Both PGD and CD had poorer intensity distributions than OW (P < 0.001). Application of a cut-point to the M30 showed 7%, 17% and 28%, of OW, PGD and CD, respectively, accumulated 30 minutes of brisk walking per day. Radar plots showed OW had higher overall activity than CD. The relatively poor intensity distribution of PGD, despite similar overall activity to OW, was due to accumulation of more light and less higher intensity activity. These data-driven methods identify aspects of activity that differ between groups, which may be missed by cut-point methods alone. Abbreviations: CD: Adults with ≥1 chronic disease; mg: Milli-gravitational unit; MVPA: Moderate-to-vigorous physical activity; OW: Office workers; PGD: Women with a history of post-gestational diabetes; VPA: Vigorous physical activity [ABSTRACT FROM AUTHOR]

The coronavirus disease 2019 (COVID-19) pandemic has impacted nonformal education, which includes children's informal learning and social development. Due to the required closings of many informal learning spaces, children have been left without methods to construct their learning physically and socially. This essay discusses how informal learning benefits children, how COVID-19 has interrupted children's receipt of those advantages, and ways in which children, families, educators, and communities can compensate for the temporary closings of informal learning spaces.

This article reviews recent literature on the contribution of curriculum physical education to health-enhancing physical activity within the context of European countries. Recommended goals for student physical activity are discussed within a curriculum framework based on five 'forms' (concept, designed, implemented, results and effects). The study used a 'rapid reviewing' method, in which sources were identified and analysed using systematic reviewing techniques, but subsequent stages were adapted to facilitate flexible and practical interpretation. Results show that physical education lessons tend not to reach a putative 50% threshold of moderate-to-vigorous intensity. Given that the average time allocated for physical education in Europe is 100 minutes per week, strategies are needed to increase the intensity and duration of physical activity in lessons if they are to make a more meaningful 'direct' contribution to the European and WHO daily target of sixty minutes of moderate to vigorous physical activity. The authors therefore consider the plausibility of introducing an 'Active Schools' concept, in which physical education lessons designed to equip students with the prerequisite knowledge, skills, attitudes, and values supportive of a physically active lifestyle are augmented by other school-based contexts which provide the opportunity to actually meet the recommended guidelines for physical activity participation.

Meta-analysis of physical activity interventions in school settings have revealed low efficacy and that there is a need to explore implementation fidelity. The aim of this rapid realist review was to determine, what physical activity interventions in school settings for children aged 7- to 11-yearsold works, for whom, and in what circumstances. The realist synthesis was conducted following RAMESES guidelines. Relevant studies were identified following a systematic search process and data from 28 studies was extracted for evidence to form context-mechanism-outcome configurations that were clustered and refined. Using the five-level socioecological model, the program theories were classified into the levels of intrapersonal (child), interpersonal (teachers), institutional (program content, school administration, and school environment), community (home and neighborhood), and policy. The school level led to most context-mechanism-outcome configurations related to school leadership and policy, workforce structure, program characteristics, and school environment. At each level, we identified features of interventions, alongside implementation considerations that might work to promote efficacy and sustainability. The need to recognize the school environment as part of a complex system with multi-level interaction and influences was a key finding. In line with realist philosophy, the researchers encouraged primary research to confirm, refute, and refine the program theories presented. [ABSTRACT FROM AUTHOR]

Background: School-based interventions are a key opportunity to improve children's physical activity (PA); however, there is lack of evidence about how pedagogical approaches to motor learning in physical education (PE) might affect PA in children. Therefore, this study aimed to assess how different pedagogical approaches in PE might affect children's PA. Methods: Participants (n = 360, 5-6 years) from 12 primary schools within the SAMPLE-PE randomized controlled trial were randomly allocated to either Linear Pedagogy (LP: n = 3) or Nonlinear Pedagogy (NP: n = 3) interventions, where schools received a 15-week PE intervention delivered by trained coaches, or to a control group (n = 6), where schools followed usual practice. ActiGraph GT9X accelerometers were used to assess PA metrics (moderate-to-vigorous PA, mean raw acceleration and lowest acceleration over the most active hour and half hour) over whole and segmented weeks at baseline, immediately post-intervention and 6 months follow-up. Intention to treat analysis employing multilevel modelling was used to assess intervention effects. Results: LP and NP interventions did not significantly affect children's PA levels compared to the control group. Conclusion: PE interventions based on LP and NP alone might not be effective in improving habitual PA in children. [ABSTRACT FROM AUTHOR]

(1) Background: Family is considered as one of the most important elements for the transmission of healthy habits that improve the lives of students. For this reason, the present study aims to describe the degree of family functionality, emotional intelligence, Mediterranean diet adherence, and extra-curricular physical activity engagement. A further aim is to perform a correlational analysis between these variables. (2) Methods: To this end, an ad hoc questionnaire was used, alongside the APGAR, KIDMED, and Trait Meta Mood Scale (TMMS-24). (3) Results: Finally, the data suggest that a high percentage of students need to improve their diet. Further, students reporting severe family dysfunction showed worse outcomes. Thus, levels of emotional clarity were lower when family functionality was poor. Poor diet quality was also associated with lower emotional attention, with Mediterranean diet adherence being positively related to emotional clarity and repair, as well as normal family functionality. (4) Conclusions: Boys showed higher levels of adherence to the Mediterranean diet adherence, while girls reported higher family functionality. Thus, compliance with the minimum recommendations for physical activity engagement was associated with adequate adherence to the Mediterranean diet. The importance of diet for obtaining an optimal physical condition, adequate emotional state, and family functionality is highlighted. [ABSTRACT FROM AUTHOR]
