Moderate-to-vigorous physical activity and sedentary behavior in children with and without developmental coordination disorder: Associations with fundamental movement skills

Background: There is a pandemic of physical inactivity in children. Compared to children with typical development (TD), those with developmental coordination disorder (DCD) are less physically active. Mastery of movement skills such as fundamental movement skills (FMS) are potential correlates of physical activity. Aims: To examine the associations of FMS with moderate-to-vigorous physical activity (MVPA) and sedentary behavior (SB) in children with DCD and TD. Methods and procedures: This cross-sectional study included 172 children with DCD (n = 73; boys = 49) or TD (n = 99; boys = 48) aged 6-10 years. Five components of FMS (running, jumping, throwing, catching, kicking) were assessed using process- and product- oriented approaches using the Test of Gross Motor Development-second edition. The time spent in MVPA and SB was measured using accelerometers. Outcomes and results: Children with DCD had significantly poorer performance in FMS proficiency in terms of specific movement patterns (jumping and catching) and outcomes (running, jumping, catching, and kicking) when compared to children with TD. MVPA and SB were significantly associated with certain process-oriented FMS assessments in children, which was moderated by motor coordination status and sex. Movement patterns of catching (odds ratio = 1.686, p < .05) was a significant predictor of children's attainment of the MVPA guideline. Conclusions and implications: It is important to develop FMS patterns and ball skills in early childhood, particularly for children with DCD, to combat physical inactivity and its related health problems.
