An exploratory analysis examining differences in physical activity and motor competence in children with and without asthma: brief report.

Objective: The purpose of this pilot study was to examine potential differences in motor competence (MC) and physical activity (PA) between children with and without asthma. Methods: Thirty-seven children and adolescents completed the Exercise for a Healthy Asthma Lifestyle and Enjoyment study (46% with asthma, 51% female, 11.1 ± 0.4 y, and 46% White). Motor competence was assessed using the Movement Assessment Battery for Children 2nd edition (MABC-2). PA was assessed using accelerometry. Results: Children with asthma had significantly lower MC in the domain of aiming and catching (with asthma: 8.2 ± 0.4 vs. without asthma: 9.9 ± 0.5; p = 0.03) and fewer daily minutes spent in moderate-to-vigorous PA (MVPA) (with asthma: 18.0 ± 2.3 min vs. without asthma: 27.2 ± 3.6 min; p = 0.047). There were no significant group differences in manual dexterity, balance, total MABC-2 score, or total daily PA (all ps > 0.05). Conclusion: This study provides confirmatory evidence that children with asthma display lower MC and spend less time in MVPA compared to children without asthma. Because MC is a prerequisite for engaging in PA, future research should seek to determine if the differences observed in MC contribute to disparities in MVPA observed in this clinical population.
