A Randomized Controlled Trial of a Blended Physical Literacy Intervention to Support Physical Activity and Health of Primary School Children

The benefits of physical literacy for human flourishing: A machine learning-based exploration of adolescents

Physical literacy is a multidimensional concept considered fundamental for lifelong participation in physical activity. Although theories on the relationship between physical literacy and human flourishing have been proposed, no comprehensive study of this relationship in adolescents has been found. This study aimed to predict human flourishing variables (physical activity, physical health, mental health, and academic performance) that correlate highly with adolescents' physical literacy. A sample of 1004 primary and middle school students was recruited and six machine learning algorithms (decision tree, random forest, AdaBoost, CatBoost, LightGBM, and k-nearest neighbours) were used. Random forest predicted physical activity, physical health, and mental health in the overall sample, with an accuracy of 53 percent, 86 per cent, and 91.7 percent, respectively; AdaBoost predicted academic performance with an accuracy of 98 per cent. Overall sample and sex subgroup predictions were generally consistent, with "sense of self and self-control" and "self-expression and communication with others" as the most significant variables. Family-type subgroup analysis results varied greatly, suggesting that one-child families should focus on "knowledge and understanding," whereas multi-child families should focus on "self-expression and communication with others." Awareness of adolescents' underlying characteristics may yield greater benefits when intervening through physical literacy.

Effectiveness of a school-based high-intensity interval training intervention in adolescents: study protocol of the PRO-HIIT cluster randomised controlled trial

Introduction

High-intensity interval training (HIIT) is an effective strategy for improving a variety of health and fitness outcomes within school settings. Incorporating HIIT into existing physical activity opportunities appears practically feasible, yet the process evaluation and effectiveness of this strategy needs to be further evaluated. Therefore, a PRO-HIIT intervention will be conducted to evaluate the effectiveness of a 12-week school-based HIIT intervention on cardiorespiratory fitness, physical activity, body composition, muscular strength, bone health, cognitive function, wellbeing and academic performance among 12-13-year-olds.

Methods and analysis

Eight classes of year 7 students (12-13-year-olds) from a secondary school in Ningbo, China, will be recruited and randomly allocated into an intervention or control group. While the control group maintains their usual activities, a 6 to 10 min HIIT session will be embedded in the physical education or physical activity lessons five days a week for 12 weeks for the intervention group. Training workshops will be conducted for participants, teachers, and research staff for facilitating the intervention. Outcome data will be collected at three time points: pre- and post-intervention, and two months (summer holiday) upon completion of the intervention. Linear mixed models will be used to analyse the impact of groups (intervention and control), timepoints (pre-, post- and two-month after intervention) and group by time interactions. The implementation process of the intervention will be evaluated using a process evaluation framework.

Ethics and dissemination

Ethics approval is obtained from the Ningbo University Ethics Committee (TY2024002). Results from PRO-HIIT study will be disseminated via peer-reviewed journals, scientific conferences as well as local education system. The study protocol has been retrospectively registered on ClinicalTrials.gov Protocol Registration and Results System (NCT06374732), https://clinicaltrials.gov/study/NCT06374732.

Stakeholder perceptions of physical literacy: results from a national consultation in England

Background

There is a lack of evidence of stakeholder perspective and understanding of physical literacy among relevant stakeholders from England. As part of research commissioned by Sport England to develop a physical literacy consensus statement for England, this study presents findings from the first national consultation with stakeholders in England.

Methods

One hundred and ninety-three individual stakeholders (50.3%) from education, community sport, national governing bodies of sport, physical activity and sport coaching sectors completed an online survey consisting of fixed item and open ended questions designed to examine their knowledge, understanding, perceptions and practices relating to physical literacy.

Results

Responses from stakeholders suggested there was confusion in use of the term physical literacy in practice and confusion regarding the definition of physical literacy. Most respondents suggested they were involved in physical literacy related activity and understood the term. However, when probed the physical literacy related activity they referred to was likely not actually physical literacy related. Understanding of the term physical literacy was inconsistent in general. Stakeholders considered the affective, social, physical and cognitive areas (domains) of learning to be most important for developing a positive relationship with movement, sport and physical activity for life.

Conclusions

While stakeholders are aware of the term "physical literacy" and hold value of it within their practice, there remain key misconceptions relating to what physical literacy is, and debate as to whether any existing definitions truly capture the construct of physical literacy.

Effects of Holistically Conceptualised School-Based Interventions on Children's Physical Literacy, Physical Activity, and Other Outcomes: A Systematic Review

BACKGROUND

Schools are a key setting for promoting children's physical literacy development. This review aimed to identify school-based interventions that adopted a holistic conceptualisation of physical literacy and examine the effects on children's physical literacy and any other outcomes, including physical activity (PA).

METHODS

Searches were conducted in seven databases (APA PsycINFO, EMBASE, ERIC, CINAHL, Global Health, MEDLINE Complete, SPORTDiscus with Full Text), and Google and Google Scholar, to identify articles published since 1/1/2017. Studies were included if they (i) adopted a holistic conception of physical literacy as represented by the Australian Physical Literacy Framework (APLF), (ii) were grounded in movement, (iii) assessed three or more domains of learning (either quantitatively or qualitatively), and (iv) included children aged 5-14 years. Quantitative research designs needed to provide pre-and post-intervention measures, whereas qualitative designs (e.g. post-intervention interviews) did not. Study selection, data extraction and quality assessment were conducted independently by teams of two authors. For intervention effects, quantitative and qualitative data were synthesised separately. For quantitative data, level of evidence for intervention effects was assessed by physical literacy domain and/or elements/items by examining the proportion of tests with a significant change in the expected direction. Qualitative data were synthesised using the framework synthesis method and mapped to a framework that included APLF domains/elements, PA, and additional outcomes.

RESULTS

Twelve interventions with 1,427 participants from seven countries were identified: six physical education-based, three afterschool, one structured recess, and two multicomponent. All studies assessed the physical domain quantitatively, with strong positive evidence of intervention effects for the controlled designs (10 of 15 tests). For the affective and cognitive domains, evidence was mixed, and there was no evidence for interventions improving the social components of children's physical literacy (although this was understudied). Most studies assessed PA and one measured cognitive performance; however, there was no evidence for positive intervention effects (i.e. ≥35% of tests reporting an improvement) for either outcome. Five studies assessed intervention effects qualitatively, with positive results reported for all physical literacy domains, PA, and cognitive performance.

CONCLUSIONS

Holistic interventions in schools can improve the physical domain of children's physical literacy. For wider benefits, future interventions should aim to develop all facets of physical literacy, especially domains of learning less frequently targeted and examined.

Assessment of physical literacy in 8- to 12-year-old Pakistani school children: reliability and cross-validation of the Canadian assessment of physical literacy-2 (CAPL-2) in South Punjab, Pakistan

BACKGROUND

The increasing prevalence of physical inactivity, declining fitness, and rising childhood obesity highlight the importance of physical literacy (PL), as a foundational component for fostering lifelong health and active lifestyle. This recognition necessitates the development of effective tools for PL assessment that are applicable across diverse cultural landscapes.

AIM

This study aimed to translate the Canadian Assessment of Physical Literacy-2 (CAPL-2) into Urdu and adapt it for the Pakistani cultural context, to assess PL among children aged 8-12 years in Pakistan.

METHOD

The Urdu version of CAPL-2 was administered among 1,360 children aged 8-12 from 87 higher secondary schools across three divisions in South Punjab province, Pakistan. Statistical analysis includes test-retest reliability and construct validity, employing confirmatory factor analysis to evaluate the tool's performance both overall and within specific subdomains.

RESULTS

The Urdu version of CAPL-2 demonstrated strong content validity, with a Content Validity Ratio of 0.89. Confirmatory factor analysis supported the four-factor structure proposed by the original developers, evidenced by excellent model fit indices (GFI = 0.984, CFI = 0.979, TLI = 0.969, RMSEA = 0.041). High internal consistency was observed across all domains (α = 0.988 to 0.995), with significant correlations among most, excluding the Knowledge and Understanding domains. Notably, gender and age significantly influenced performance, with boys generally scoring higher than girls, with few exceptions.

CONCLUSION

This study marks a significant step in the cross-cultural adaptation of PL assessment tools, successfully validating the CAPL-2 Urdu version for the Pakistani context for the first time. The findings affirm the tool's suitability for assessing PL among Pakistani children, evidencing its validity and reliability across the Pakistani population.

School-based promotion of physical literacy: a scoping review

Introduction

The role of physical activity in children's healthy development is undisputed, with school-based interventions being seen as a priority. The promotion of physical literacy (PL) seems to be promising due to its holistic approach, combining physical, cognitive, and affective domains. To develop recommendations for possible measures, we compiled existing literature on existing school-based PL interventions.

Methods

Five databases (MEDLINE, Web of Science, SPORTDiscus, ERIC, and PsycInfo) were searched between July 6 and July 10, 2023, by combining the terms "physical literacy," "school," "program," "workshop," "intervention," and "curriculum" as well as a manual search. Records were screened in a two-stage process by two independent authors using a priori criteria. Eligible studies concerned PL interventions in the school context. The included records were sorted according to school type/population, structure, content, PL domains addressed, and evaluation.

Results

In total, 706 articles were found through the database search and an additional 28 articles through the manual search. After removing duplicates, 502 publications remained, which were screened by title and abstract, leaving 82 full texts. These were cut down to 37 articles describing 31 different programs (19 in primary schools, eight in secondary schools, one in both primary and secondary schools, and three unspecified). Most interventions were conducted during physical education classes (n = 12). All three PL domains were addressed by five interventions, while 11 interventions solely concerned the physical domain. In addition, 21 interventions evaluated their effects on PL. Most evaluations showed small to moderate but inconsistent effects on several PL-related constructs (e.g., self-efficacy, motivation, movement skills). Interventions incorporating all three domains reported positive effects on physical competence and enjoyment.

Discussion

Although there is a growing body of data related to school-based PL promotion, their effects and practical application remains relatively underdeveloped: study designs, study quality, PL assessments, and results are heterogeneous. Corresponding research adhering to the holistic approach of PL will be crucial in clarifying the potential lifelong role of PL in promoting physical activity, increasing health and well-being and to actually enable development of recommendations for action.

Physical Fitness of Chinese Primary School Students across the Coronavirus (COVID-19) Outbreak: A Retrospective Repeated Cross-Sectional Study

Social distancing measures against COVID-19 imposed restrictions on students that may have affected their physical health and fitness. The objective of this study was to investigate the change in physical fitness of primary school students across the coronavirus outbreaks from 2019 to 2021. This was a retrospective repeated cross-sectional study. We obtained the annual physical and fitness assessment data measured every November for all students at the same primary school in Guangzhou, China. There was a total of 6371 observations in the dataset for three years. The physical fitness of the students was evaluated with an overall physical fitness score, body mass index (BMI), lung vital capacity, physical flexibility (via a sit-and-reach test) and sports task performances (sprint, shuttle run, rope-jumping, and sit-up). Generalised estimating equations were used to determine any significant changes from 2019 to 2021, adjusted for confounders. After the COVID-19 outbreak in 2021, there was a significant elevation in BMI of 0.64 kg/m2 in 2020 and 0.39 kg/m2 in 2021 (p < 0.001). The overall physical fitness score was significantly increased by 2.1 and 4.1 points, respectively, in 2020 and 2021 (p < 0.001). Lung vital capacity and rope-jumping performance were significantly improved in both 2020 and 2021 compared with 2019, and sit-up performance was marginally significantly improved in 2020 and significantly improved in 2021. However, students demonstrated poorer flexibility and sprint and shuttle run performance in 2021 compared with 2019. A health promotion programme during and after COVID-19, including online physical education classes, television broadcasts, and a rope-jumping campaign, could account for these positive outcomes, along with the ease of administering rope-jumping and sit-ups at home.

Adolescents with Higher Cognitive and Affective Domains of Physical Literacy Possess Better Physical Fitness: The Importance of Developing the Concept of Physical Literacy in High Schools

Physical literacy (PL) is thought to facilitate engagement in physical activity, which could lead to better physical fitness (PF). The aim of this study was to examine the reliability of the Croatian version of two frequently applied PL questionnaires that evaluate knowledge and understanding, perceived competence, environment, and value for literacy, numeracy, and PL and validity regarding correlation with objectively evaluated PF in adolescents. Five hundred forty-four high school students (403 females, 141 males) from Croatia were tested on PF (standing long jump, sit-ups for 30 s, sit-and-reach test, multilevel endurance test) and two PL questionnaires. The reliability of the Croatian version of the Canadian Assessment of Physical Literacy knowledge and understanding (CAPL-2-KU) and PLAYself was good (α = 0.71−0.81 for PLAYself subscales, κ = 0.39−0.69 for CAPL-2-KU). Genders differed in the self-description dimension of PLAYself, with higher results in boys (Z = 3.72, p < 0.001). CAPL-2-KU and PLAYself total score were associated with PF in boys and girls, with PLAYself having stronger associations with PF. This research supports the idea of PL as an essential determinant for the development of PF, highlighting the necessity of the development of cognitive and affective domains of PL in physical education throughout a specifically tailored pedagogical process.
