Changes in body mass index (BMI) due to various factors, such as a low level of physical activity, are often associated with poor physical fitness in children with probable developmental coordination disorder (pDCD). This study examined whether children with pDCD would show poorer performance in terms of physical fitness when compared with their typically developing (TD) peers. Thirty two children with pDCD and normal BMI and other 32 children with TD and normal BMI, matched by gender, age and BMI, performed the sit and reach, standing long jump, curl-up, modified pull-up and 9-min run tests. The children in the pDCD group showed lower explosive power, muscle strength and endurance, and cardiorespiratory fitness than children in the TD group. Overall, children with pDCD had lower levels of physical fitness, even with normal BMI.
