Modulation of the Autonomous Nervous System (ANS) plays as important role in the processes of human development. However, the ANS modulation in children with Developmental Coordination Disorder (DCD) has not been explored by researchers. The goal of this study was to verify the involvement and/or the role of the Autonomous Nervous System related to children with DCD issues through the analysis of Heart Rate Variability (HRV). Spectral, symbolic and conditional entropy analyses of HRV of DCD children was compared to the Typically Developed (TD) children in the following context: (1) Testing for active postural changes, from supine to orthostatic position and (2) in different stages of a motor task, specifically during instruction, practice and assessment. The test results with active postural changes indicated that children with DCD have adequate autonomous modulation while resting in basic posture positions, similarly to TD children. HRV results during different stages of the motor task indicated that, during practice, TD children showed parasympathetic modulations significantly higher than the ones showed by DCD children. During assessment, TD children reduced parasympathetic modulation closer to the modulation pattern of children with DCD. Therefore, DCD children`s neurophysiologic systemic modulation during motor task practice and both groups (DT and TDC) neurophysiologic systemic modulation during motor task assessment were not adequate to the motor performance demands throughout learning process
