Moving well-being well: Using machine learning to explore the relationship between physical literacy and well-being in children.

Physical literacy provides a foundation for lifelong engagement in physical activity, resulting in positive health outcomes. Direct pathways between physical literacy and health have not yet been investigated thoroughly. Associations between physical literacy and well-being in children (n = 1073, mean age 10.86 ± 1.20 years) were analysed using machine learning. Motor competence (TGMD-3 and BOT-2) and health-related fitness (PACER and plank) were assessed in the physical competence domain. Motivation (adapted-Behavioural Regulation in Exercise Questionnaire) and confidence (modified-Physical Activity Self-Efficacy Scale) were assessed in the affective domain. Well-being was measured using the KIDSCREEN-27. Accuracy of predicting well-being from physical literacy was investigated using five machine learning classifiers (decision tree, random forest, XGBoost, AdaBoost, k-nearest neighbour) in the full sample and across subgroups (sex, socioeconomic status [SES], age). XGBoost predicted well-being from physical literacy with an accuracy of 87% in the full sample. Predictive accuracy was lowest in low SES participants. Contribution of physical literacy features differed substantially across subgroups. Physical literacy predicts well-being in children but the relative contribution of physical literacy features to well-being differs substantially between subgroups.

Do our movement skills impact our cognitive skills? Exploring the relationship between cognitive function and fundamental movement skills in primary school children.

OBJECTIVES: The literature suggests that there is a relationship between motor function and cognitive development however, few studies have explored the specific role of Functional Movement Skills on cognitive function. This research aimed to determine if Functional Movement Skills predict cognitive function, when accounting for confounding factors, in a sample of primary school children in Ireland. DESIGN: Cross-sectional. METHODS: Sixty primary school children (51.7 % girls, age range 7-12 years, mean age 9.9 ±â€¯1.28) were assessed in their Functional Movement Skill proficiency using the Test of Gross Motor Development-3rd Edition and a subtest of the Bruininks-Oseretsky Test of Motor Proficiency 2 Short Form (to assess balance). Participants also completed a series of cognitive tests which formed part of the Cambridge Neuropsychological Test Automated Battery. RESULTS: A series of hierarchical regression analyses were conducted whilst controlling for covariates (Age; Gender; Socio Economic Status). Attention Switching, Reaction Time, and Emotional Recognition were found to be associated with Overall Functional Movement Skills (Locomotor, Object Control, Stability). Overall Functional Movement Skills significantly accounted for 4.7 % of the variance in Simple Reaction Time (ΔR2 = 0.032; p = 0.13) whilst Stability significantly accounted for 5.5 % (ΔR2 = 0.055; p = 0.04) and 12.9 % (ΔR2 = 0.129; p = 0.00) of the variance in Simple Reaction Time and Emotional Recognition, respectively, after controlling for covariates. CONCLUSIONS: Overall Functional Movement Skills may be more related to reaction time than attention and spatial working memory, whilst stability may be more associated with emotional recognition. Further research is warranted. Greater comprehension of the impact of Functional Movement Skills on cognitive function in children can contribute to the development of more effective and efficient physical activity programmes, which can in turn contribute to and promote holistic child development.

Are all domains created equal? An exploration of stakeholder views on the concept of physical literacy.

BACKGROUND: Developing physical literacy at population levels provides a transformative appeal for those working in sport, health, education, recreation and physical activity settings. Interdisciplinary approaches to development of policy in this area is recommended. The purpose of this study was to gather empirical data from key stakeholders working with young people in areas related to physical literacy across the Republic of Ireland and Northern Ireland, to capture their current understanding and awareness of the physical literacy to help inform the development of the first all-island consensus statement for physical literacy. METHODS: A total of 1,241 participants (52% male), from a range of stakeholder groups (health, physical activity, sport, recreation and education) completed a researcher developed physical literacy questionnaire. A one-way MANOVA was carried out to investigate differences across stakeholder grouping in terms of perceived importance of three domains of physical literacy. Overlap of independent confidence intervals was analysed to determine importance of the physical literacy domains within stakeholder grouping. RESULTS: A majority (63%) of respondents indicated they were aware of an existing definition of physical literacy, but this varied by stakeholder group (e.g. 86% for higher education, versus 47% of coaches). Participants working in higher education (69%), or working as physical education specialists (67%), were more likely to rate themselves as experts or near experts in physical literacy, while coaches, education generalists, and decision makers were more likely rate themselves as having no expertise (9%, 12% and 12% respectively). Non-specialist teachers and physical education teachers rated the importance of all domains of physical literacy significantly higher than decision makers, and significantly higher than coaches in the cognitive and affective domains. All stakeholders significantly rated the importance of the physical/psychomotor domain of physical literacy higher than the affective or cognitive domains of physical literacy. CONCLUSIONS: Differences observed across stakeholder groups underline the importance of developing a shared vision for physical literacy, and the need to clarify and gain consensus on a definition of the term and its domains. Engaging and understanding the voice of stakeholders is critical in ensuring the relevance, ownership of and commitment to physical literacy statement operationalisation.

Exploring the relationships between fundamental movement skills and health related fitness components in children.

This study examined the relationship between fundamental movement skills (FMS) and health related fitness (HRF) components in children. A cross section of Irish primary school children across all age groups participated in this study (n=2098, 47% girls, age 5-12 years of age, mean age 9.2 ± 2.04). FMS were measured using the Test of Gross Motor Development (TGMD-3), along with two additional assessments of vertical jump and balance. All HRF components were also assessed: body composition through BMI and waist circumference, muscular strength (MS) using a hand dynamometer, muscular endurance (ME) through the plank test, flexibility with back-saver sit-and-reach, and cardiovascular endurance (CVE) using the 20 m PACER test. Hierarchal multiple regressions were used to measure associations between the HRF components and overall FMS and the FMS subtests: locomotor, object control and balance skills. Results show significant positive relationships between FMS and MS (R2 = 0.25, ß= -0.19), ME (R2 = 0.11, ß = 0.34), flexibility (R2 = 0.13, ß = 0.14) and CVE (R2 = 0.17, ß = 0.39), and an inverse relationship between FMS and body composition (R2 = 0.25, ß= -0.19). The data presented reinforces the position that the relationship between FMS and HRF is dynamic, and predominantly strengthens with age through the course of childhood. Findings suggest that developing FMS as a child may be important to developing HRF across childhood and into adolescence.

TGMD-3 short version: Evidence of validity and associations with sex in Irish children.

This study examined the internal structure and evidence of validity of the Test of Gross Motor Development 3rd edition (TGMD-3) in primary school aged children. Participants (n = 1608, 47% girls, age range 5-11 years, mean age 9.2 ± 2.04) were recruited from Irish schools across twelve counties (56% rural, 44% urban). The TGMD-3 was used to measure FMS proficiency (Ulrich, 2020). A two-factor model (13 skills) was used and confirmatory indexes were calculated. The Bayesian criteria and the Composite Reliability were employed to evaluate alternative models. Relationships between the final model proposed with age, sex and BMI were calculated using a network analysis. Mplus 8.0 and Rstudio were used. A two-factor model (locomotion and object control) with adequate values (> 0.30) for the seven skills (gallop, hop, jump, two-hand strike, bounce, catch, overhand throw) presented excellent indexes. The skills with the highest indicator of strength centrality in the network were bounce and catch for both boys and girls and hop for boys and horizontal jump for girls. This study evidences the validity and reliability of the internal structure of the TGMD-3 and demonstrates that a short version of the TGMD-3, comprising seven skills is a valid measure of FMS in this population.

The Differential Impact of Screen Time on Children's Wellbeing.

Increased screen time has been found to be associated with a number of negative health and wellbeing indicators in youth populations. An increasing number of studies have investigated the association between screen time and wellbeing in adolescents, but evidence in younger children is still emerging. This 2017 study explored the effect of leisure screen time and gender on dimensions of wellbeing (measured using KIDSCREEN-27) in a national sample of 897 Irish primary school children aged 8-12 years. Participants had a mean age of 10.9 ± 1.16 years and were 47.7% female. Just over 30% of the sample accumulated 2 h or more of leisure screen time daily. Results show that there was no significant interaction between screen time category (<2 h/2 h + daily) and gender on overall wellbeing, while controlling for BMI. Children who self-reported <2 h of leisure screen time scored significantly higher on four dimensions of wellbeing: physical, parental, peers, and school, but not psychological. This study supports the growing evidence of the impact that leisure screen time has on health. Further longitudinal research investigating the impact of sub-categories of leisure screen time behaviour on wellbeing is warranted.

Understanding disadvantaged adolescents' perception of health literacy through a systematic development of peer vignettes.

BACKGROUND: Adolescence represents a crucial phase of life where health behaviours, attitudes and social determinants can have lasting impacts on health quality across the life course. Unhealthy behaviour in young people is generally more common in low socioeconomic groups. Nevertheless, all adolescents should have a fair opportunity to attain their full health potential. Health literacy is positioned as a potential mediating factor to improve health, but research regarding health literacy in adolescents and socially disadvantaged populations is limited. As part of Phase one of the Ophelia (OPtimising HEalth LIterAcy) framework, The purpose of this study was to explore the perceptions of socially disadvantaged Irish adolescents in relation to health literacy and related behaviours, and utilise this data to develop relevant vignettes. METHODS: A convergent mixed method design was used to co-create the vignettes. Questionnaires were completed by 962 adolescents (males n = 553, females n = 409, Mean age = 13.97 ± 0.96 years) from five participating disadvantaged schools in Leinster, Ireland. Focus groups were also conducted in each school (n = 31). Results were synthesised using cluster and thematic analysis, to develop nine vignettes that represented typical male and female subgroups across the schools with varying health literacy profiles. These vignettes were then validated through triangular consensus with students, teachers, and researchers. DISCUSSION: The co-creation process was a participatory methodology which promoted the engagement and autonomy of the young people involved in the project. The vignettes themselves provide an authentic and tangible description of the health issues and health literacy profiles of adolescents in this context. Application of these vignettes in workshops involving students and teachers, will enable meaningful engagement in the discussion of health literacy and health-related behaviours in Irish young people, and the potential co-designing of strategies to address health literacy in youth. CONCLUSION: As guided by the Ophelia framework, the use of authentic, interactive and participatory research methods, such as the co-creation of vignettes, is particularly important in groups that are underserved by traditional research methods. The approach used in this study could be adapted to other contexts to represent and understand stakeholders' perceptions of health, with a view to explore, and ultimately improve, health literacy.

Movement competence: Association with physical self-efficacy and physical activity.

BACKGROUND: The purpose of this paper was to investigate whether physical self-efficacy mediates the relationship between movement competence (fundamental movement skills and perceived movement skill competence) and physical activity in children. METHODS: A purposive sample of 860 children (47.7% female, 10.9 ± 1.16 years) were recruited and completed assessments for physical self-efficacy (Physical Activity Self-Efficacy Scale), fundamental movement skills (Test of Gross Motor Development-3), perceived movement skill competence (Pictorial Scale of Perceived Movement Skill Competence), and physical activity (PACE+). A bootstrap mediation analysis was employed using movement competence as the predictor variable and physical activity as the outcome variable, and physical self-efficacy as the potential mediator of the relationship. RESULTS: The results from a bootstrap mediation analysis yielded a statistically significant mediation effect for physical self-efficacy, with the entire model explaining approximately 10.3% of the variance of physical activity. The indirect effect of perceived movement skill competence through physical self-efficacy was significantly larger than the indirect effect of fundamental movement skills through physical self-efficacy. Neither sex nor age acted as a covariate. CONCLUSION: Movement competence (fundamental movement skills and perceived movement skill competence) acts as a source of information for children's physical self-efficacy, moreover physical self-efficacy mediates the movement competence - PA relationship. Findings highlight the need for interventions to target and improve movement competence as a whole for children.

Moving Well-Being Well: Investigating the maturation of fundamental movement skill proficiency across sex in Irish children aged five to twelve.

Fundamental movement skills (FMS) are the basic building blocks of more advanced, complex movements required to participate in physical activity. This study examined FMS proficiency across the full range of Irish primary school children (n = 2098, 47% girls, age range 5-12 years). Participants were assessed using the Test of Gross Motor Development, 3rd edition (TGMD-3), Victorian Fundamental Movement skills manual, and the balance subtest from the Bruininks-Oseretsky Test of Motor Proficiency 2 (BOT-2). Independent sample t-tests and a one way between groups ANOVA with planned comparisons were used analyse sex and age differences. Mastery or near mastery of skills ranged from 16% for overhand throw, to 75.3% for run. Girls scored significantly higher than boys in the locomotor and balance subtests with the boys outperforming the girls in object control skills. Improvements in ability can be seen over time (F(8,1968) = 70.18, p < 0.001), with significant increases in FMS proficiency seen up to the age of 10, after which proficiency begins to decline. The findings demonstrate the low levels of FMS proficiency amongst Irish primary school children, the differences between sex that exist, and highlights the need for more programmes that focus on developing these FMS at an early age.
