Perceived athletic competence and physical activity in children with developmental coordination disorder who are clinically referred, and control children.

The relationship between perceived athletic competence (PAC) and physical activity (PA) in children with developmental coordination disorder (DCD) is still unclear. This study investigated differences in PAC and PA between, and within, a group of children with DCD that were clinically referred (n = 31) and a group of control children (n = 38), aged 7-12 years. All children were categorized in four groups: (1) children with DCD/low PAC, (2) children with DCD/normal to high PAC, (3) control children/low PAC, and (4) control children/normal to high PAC. PAC was assessed with the Self-Perception Profile for Children, and PA was assessed with the Modifiable Activity Questionnaire. Children with DCD participated less in unorganized PA, but not in organized PA, compared with control children. Normal to high PAC was found in more than half of the children (64.5%) with DCD. Children with DCD/low PAC and children with DCD/normal to high PAC participated significantly less in unorganized physical activity compared with control children/normal to high PAC, but not compared with control children/low PAC. The results indicate that there are large individual differences in PAC in children with DCD.

Relationship between participation in leisure time physical activities and aerobic fitness in children with DCD.

PURPOSE: (1) To explore participation in leisure time physical activities (LTPAs) in children with developmental coordination disorder (DCD) compared with children developing typically. (2) To examine the association between participation in LTPA and aerobic fitness. METHODS: Thirty-eight children with DCD (aged 7-12 years) were age and gender matched with 38 children developing typically. Participation in LTPA was self-administered by using an activity questionnaire, and aerobic fitness was estimated using a Shuttle Run Test. RESULTS: Children with DCD spent significantly less time in overall, nonorganized, and vigorous LTPA compared with children developing typically. Aerobic fitness was significantly lower for children with DCD. The best model, including age, group, and overall LTPA, explained 46.2% of the variance in aerobic fitness. CONCLUSIONS: Suitable physical activities should be fostered in children with DCD, who have a low participation rate and aerobic fitness level.
