The Influence of Motor Competence on Broader Aspects of Health: A Systematic Review of the Longitudinal Associations Between Motor Competence and Cognitive and Social-Emotional Outcomes

BACKGROUND

Motor competence has important developmental associations with aspects of physical health, but there has been no synthesis of longitudinal associations with cognitive and social-emotional health.

OBJECTIVES

The first aim was to present a conceptual model that positions motor competence as a mediator between physical activity and cognitive and social-emotional outcomes. The second aim was to synthesize the association of motor competence and cognitive and social-emotional development using longitudinal observational and experimental evidence, in particular to (i) identify the role of task, individual, and environmental characteristics in moderating the association between motor and cognitive and social-emotional outcomes and (ii) synthesize the strength of evidence pertaining to domain-specific relationships.

METHODS

This systematic review was registered with the International Prospective Register of Systematic Reviews (PROSPERO) and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement for reporting systematic reviews and meta-analyses. Five electronic databases (PubMed, Web of Science, Scopus, PsycINFO, and SPORTDiscus) were systematically searched. Following study screening and risk-of-bias assessment by two authors, 49 eligible studies were identified for inclusion and grouped by study design. Evidence for domain-specific paths between motor competence and cognitive and social-emotional outcomes was synthesized by calculating the significant analyses in the hypothesized direction, divided by the total number of analyses for that path. These percentages were then collated for each domain outcome. This collated influence was classified as either no association (0-33%), written as '0', or indeterminate/inconsistent (34-59%), written as '?' If there were fewer than three studies in the domain, the strength of evidence was classified as insufficient (I).

RESULTS

Of the 49 studies, 35% were able to satisfy six or more of the seven risk-of-bias criteria. Longitudinal observational evidence about domain-specific and global associations of motor competence and cognitive and social-emotional development is indeterminate. The included studies also did not provide evidence for a consistent moderating role of age and sex. Some preliminary experimental evidence does support the role of motor competence in moderating the influence of cognitively enriched physical activity on cognitive outcomes, especially working memory and social-emotional skills. However, too few studies were appropriately designed to acknowledge the moderating role of contextual mechanisms.

CONCLUSIONS

Between-study heterogeneity means it was not possible to identify definitive domain- and construct-specific relationships between motor competence and cognitive and social-emotional outcomes. To further develop our understanding, it is important that researchers acknowledge the complexity of these relationships within rigorous study designs.

Cross-Lagged Associations between Physical Activity, Motor Performance, and Academic Skills in Primary School Children

PURPOSE

Few longitudinal studies have investigated the interwoven longitudinal dynamics between physical activity (PA), motor performance, and academic skills in middle childhood. Therefore, we investigated the cross-lagged associations between PA, motor performance, and academic skills from grade 1 to grade 3 in Finnish primary school children.

METHODS

A total of 189 children 6-9 yr old at baseline comprised the study sample. Total PA was assessed using a questionnaire filled out by parents, moderate-to-vigorous PA by combined heart rate and body movement monitor, motor performance by 10 × 5-m shuttle run test, and academic skills by arithmetic fluency and reading comprehension tests in grade 1 and grade 3. Data were analyzed using structural equation modeling adjusted for gender, parental education, and household income.

RESULTS

The final model fitted the data very well ( χ237 = 68.516, P = 0.0012, root-mean-square error of approximation = 0.067, comparative fit index = 0.95, Tucker-Lewis Index = 0.89) and explained 91% of variance in the latent academic skills variable, 41% of the variance in the latent PA variable, and 32% of variance in motor performance in grade 3. Better motor performance in grade 1 was associated with higher academic skills in grade 3, but it did not predict PA. PA was not directly or indirectly associated with academic skills. However, higher levels of PA in grade 1 predicted better motor performance in grade 3. Academic skills did not predict PA or motor performance.

CONCLUSIONS

These results suggest that better motor performance, but not PA, predicts later academic skills. Academic skills in grade 1 do not contribute to PA or motor performance in the early school years.

How Do Health, Biological, Behavioral, and Cognitive Variables Interact over Time in Children of Both Sexes? A Complex Systems Approach

The present study examined gender differences in health, physical activity, physical fitness, real and perceived motor competence, and executive function indicators in three time points, and analyzed the dynamic and non-linear association between health, biological, behavioral, and cognitive variables in children followed over time. A total of 67 children (aged between six and 10 years) were followed during two years and split into two cohorts (six to eight years old: C1; eight to 10 years old: C2). Data regarding health, physical activity, real and perceived motor competence, physical fitness, and executive function indicators were obtained according to their respective protocols. Comparison tests and network analysis were estimated. Significant gender differences were found in both cohorts. The emerged networks indicated different topologies in both cohorts. No clusters were observed between the variables in C1, and there was a greater number of interactions at eight years of age. Sparse networks were observed in children aged eight and 10 years in C2, and greater connectivity was observed at nine years of age between health, physical fitness, motor competence, and physical activity indicators. This study showed that there are non-linear dynamic relationships between health, biological, behavioral, and cognitive variables over time during child development.
