Motor competence interventions in children and adolescents - theoretical and atheoretical approaches: A systematic review

This study aimed to compare for the first time the immediate and retention effects of theory-based and atheoretical motor competence (MC) interventions, by conducting a systematic review to determine which intervention approach resulted in the most improvements for motor outcomes. In accordance with PRISMA guidelines, studies were identified from searches across seven databases, for articles relating to theory-based (Achievement Goal Theory, Dynamic Systems Theory, and Social-Cognitive Theory) and atheoretically-derived MC interventions in typically developing children and adolescents. Publication bias was assessed using an adapted form of Consolidated Standards of Reporting Trials statement. Of the thirty two included studies, seventeen utilized theory-based intervention approaches. The majority of studies were grounded in Achievement Goal Theory. Also, the majority of MC interventions elicited immediate (short) and/or long-term effects for children and adolescents. Studies varied with regards to intervention components and MC assessment. Many studies scored poorly for risk of bias items. Overall, the levels of success for theoretical and atheoretical intervention programmes were not distinguishable. Findings open up new horizons for motor skills instruction to be taught using developmentally appropriate pedagogy, a research field which has gained significant traction among stakeholders in recent years.

Effect of Wii Fit training on visual perception and executive function in boys with developmental coordination disorders: A randomized controlled trial

BACKGROUND

This paper elucidated the influence of Wii Fit training on visual perception and executive function in boys with developmental coordination disorders (DCD).

METHODS

50 school boy with DCD (Mean Age = 9.55 ± 2.24) were randomly assigned to one of two groups, Wii Fit training (intervention; n = 25) or usual school program (control; n = 25). Visual perception and executive function were measured pre-, post- (8 weeks, 3 sessions per week, 30 minute per session), using Cognitive Assessment System (CAS) and Test of Visual-Perceptual Skills-Revised (TVPS-R), respectively. Pre- and post-test changes in executive function and visual perception were calculated using one-way ANCOVA, with pre-test values as covariate and post-test values as dependent variables.

RESULTS

The findings show that the rates of change in total score of visual perception from pre to post were significantly different between groups (F(1, 47) = 660.76, P = 0.024). Similarly, intervention group showed significantly different rates of change in total score of executive function from pre to post (F (1, 47) = 26.15, P = 0.013).

CONCLUSION

Findings support that when developing interventions for the improvement or management of visual perception and executive function in children with DCD, key stakeholders should include the Wii Fit training programs.

Parental and Peer Support Matters: A Broad Umbrella of the Role of Perceived Social Support in the Association between Children's Perceived Motor Competence and Physical Activity

(1) Background: This study aimed to examine the role of social support in the relationship between perceived motor competence (MC) and physical activity (PA), according to the conceptual model of Motor Development. (2) Methods: Participants were 518 students (46.5% girls), 8–12 years old. By using a structural equation modeling approach, path analysis was used to test the actual-perceived MC relationship and the mediating influence of social support on the perceived MC–PA relationship. Analyses were done with age and sex as covariates. (3) Results: The results showed a good model fit (CFI = 0.98; RMSEA = 0.07; SRMR = 0.02), where actual MC was positively associated with perceived MC (ß = 0.26, p < 0.001), which in turn was positively related to social support (ß = 0.34, p < 0.001). The model showed the direct social support-PA path (ß = 0.42, p < 0.001) and the indirect path from perceived MC through social support to PA (ß = 0.14, p < 0.001). (4) Conclusions: This study confirms that social support mediates the perceived MC–PA relationship. As such, it is not only important to build and develop children’s actual and perceived MC, but also to promote social support for PA engagement.
