The purpose of this study was to compare cardiopulmonary fitness and endurance in 9-11-year-old children with DCD against a group of typically developing children in Taiwan. The Movement ABC test was used to evaluate the motor abilities of children. Forty-one participants (20 children with DCD and 21 children without DCD) were recruited for this study. The cardiopulmonary tests included the 800-m run test and the peak oxygen consumption (peak VO(2)) test using the Bruce treadmill protocol. No significant differences in age, body height, body weight, body mass index, and percentage of body fat between children with DCD and without DCD were found. However, there were significant differences in the cardiopulmonary endurance tests between children with DCD and without DCD. Children with DCD had significantly lower peak VO(2) results than children without DCD. In addition, children with DCD ran 800 m in a slower time than children without DCD. A significant negative correlation (r=-0.437) was found between the peak VO(2) results and time to completion for the 800-m run test. Based on the results, cardiopulmonary endurance in children with DCD was worse than that of children without DCD. Due to the small sample size in this study, the results may not be a direct reflection of the entire population.
