Study protocol to examine the effects of acute exercise on motor learning and brain activity in children with developmental coordination disorder (ExLe-Brain-DCD)
Developmental coordination disorder (DCD) is one of the most prevalent pediatric chronic conditions. Without proper intervention, significant delays in motor skill performance and learning may persist until adulthood. Moderate-to-vigorous physical exercise has been proven to improve motor learning (adaptation and consolidation) in children with or without disorders. However, the effect of a short bout of physical exercise on motor adaptation and consolidation in children with DCD has not been examined. Furthermore, the role of perceptual-motor integration and attention as mediators of learning has not been examined via neuroimaging in this population.
Therefore, the primary aims of this project will be to compare children with and without DCD to (a) examine the effect of acute exercise on motor learning (adaptation and consolidation) while performing a rotational visuo-motor adaptation task (rVMA), and (b) explore cortical activation in the dorsolateral- and ventrolateral-prefrontal cortex areas while learning the rVMA task under rest or post-exercise conditions.
One hundred twenty children will be recruited (60 DCD, 60 controls) and within-cohort randomly assigned to either exercise (13-minute shuttle run task) or rest prior to performing the rVMA task. Adaptation and consolidation will be evaluated via two error variables and three retention tests (1h, 24h and 7 days post adaptation). Cortical activation will be registered via functional near-infrared spectroscopy (fNIRS) during the baseline, adaptation, and consolidation.
We expect to find exercise benefits on motor learning and attention so that children with DCD profiles will be closer to those of children with typical development. The results of this project will provide further evidence to: (a) better characterize children with DCD for the design of educational materials, and (b) establish acute exercise as a potential intervention to improve motor learning and attention.

Motor Skills in Children Aged 7–10 Years, Diagnosed with Autism Spectrum Disorder
This study used the Movement Assessment Battery for Children (M-ABC2) to assess motor skills in children aged 7–10 years with autism (
n
= 18) in comparison to two groups of age-matched typically developing children; a receptive vocabulary matched group (
n
= 19) and a nonverbal IQ matched group (
n
= 22). The results supported previous work, as indicated by a significant general motor impairment in the group with autism. However, sub-analysis of the M-ABC2 revealed that there were only 2 out of 8 subcomponent skills which showed universal significant specific deficits for the autism group; i.e. catching a ball and static balance. These results suggest that motor skill deficits associated with autism may not be pervasive but more apparent in activities demanding complex, interceptive actions or core balance ability.

Learning better by repetition or variation? Is transfer at odds with task specific training?
Transfer of motor skills is the ultimate goal of motor training in rehabilitation practice. In children with Developmental Coordination Disorder (DCD), very little is known about how skills are transferred from training situations to real life contexts. In this study we examined the influence of two types of practice on transfer of motor skills acquired in a virtual reality (VR) environment.
One hundred and eleven children with DCD and their typically developing (TD) peers, aged 6-10 years (M = 8.0 SD = 1.0) were randomly assigned to either variable (n = 56) or repetitive practice (n = 55). Participants in the repetitive practice played the same exergame (ski slalom) twice weekly for 20 minutes, over a period of 5 weeks, while those in the variable group played 10 different games. Motor skills such as balance tasks (hopping), running and agility tasks, ball skills and functional activities were evaluated before and after 5 weeks of training.
ANOVA repeated measures indicated that both DCD and TD children demonstrated transfer effects to real life skills with identical and non-identical elements at exactly the same rate, irrespective of the type of practice they were assigned to.
Based on these findings, we conclude that motor skills acquired in the VR environment, transfers to real world contexts in similar proportions for both TD and DCD children. The type of practice adopted does not seem to influence children's ability to transfer skills acquired in an exergame to life situations but the number of identical elements does.

The effects of VR-based multi-task sensorimotor intervention on motor performance in children with ADHD and DCD comorbidity
Attention-Deficit/Hyperactivity Disorder (ADHD) and Developmental Coordination Disorder (DCD) are two prevalent neurodevelopmental disorders among children. Both of these diseases, occurring independently or in combination, can result in significant motor skill deficits. The purpose of this study was to observe the improvement in motor performance and skill acquisition of children with ADHD + DCD in comparison with their peers with ADHD or DCD, through repeated practice in the MTSI game. A total of 139 children (37 ADHD, 33 ADHD + DCD, 34 DCD, 35 TD: Typically Developing) participated in the MTSI (Multi-task Sensorimotor Intervention), which involved five sensorimotor intervention tasks. The change of motor performance scores provided by the MTSI system was assessed with repeated measurements, and the skill acquisition in gross & fine motor skills before and after intervention was analyzed with a mixed-design repeated measures ANOVA with post hoc analysis. All groups of children demonstrated a significant increase in motor performance during repeated practice in MTSI and displayed great improvements in gross and fine motor skills, with ADHD + DCD children benefiting more in the magnitude. Multi-task sensorimotor intervention (MTSI) can effectively improve gross and fine motor skills for children with ADHD or DCD, and particularly for those with ADHD and DCD comorbidity, with tailored, multidimensional intervention strategies.

Physical Literacy, Physical Activity and Health: Toward an Evidence-Informed Conceptual Model
Physical literacy (PL) provides a powerful lens for examining movement in relation to physical activity (PA) and motor skill outcomes, environmental context, and broader social and affective learning processes. To date, limited consideration has been given to the role PL plays in promoting positive health behaviours. There is no clear conceptual framework based on existing empirical evidence that links PL to health, nor has an evidence-informed case been made for such a position. The purpose of this paper is to (1) present a conceptual model positioning PL as a health determinant, and (2) present evidence in support of PL as a health determinant, drawing on research largely from outside physical education. Viewing PL from the perspective of a multidimensional, experiential convergence process enables it to be differentiated from other models. However, parallels between our model and existing models that focus on movement competence are also drawn. Arguing from a pragmatic perspective on PL, we present evidence for positioning PL as a determinant of health from two literature sources: research on motor coordination disorders in children, and associations between motor competence, PA and health in typically developing children. Statistical modelling approaches consistent with the concept of PL are discussed. Results from these approaches—confirmatory factor analysis and cluster analysis—support the idea that measures related to motor competence, motivation and positive affect work in an integrative manner to produce differences in PA and subsequent health outcomes in children. There is increasing interest in PL, particularly in the field of public health. Presenting a model that explicitly links PL to health can lead to the generation of new research questions and the possibility of broadening impact beyond the context of physical education alone. To date, there has been little conceptual attention to what positioning PL as a determinant of health means. By providing an evidence-based model of PL as a determinant of health, we hope to further the discussion and stimulate increased empirical research in the field.
