Insights

Children with developmental coordination disorder (DCD) have lower cardiorespiratory fitness and muscle strength compared to typically developing children (TDC). Poor balance is linked to reduced cardiorespiratory fitness in these children.

Area of Science:

  • Pediatric physical therapy
  • Developmental pediatrics
  • Exercise science

Background:

  • Developmental Coordination Disorder (DCD) affects motor skills in children.
  • Health-related physical fitness components are crucial for overall child development.
  • Limited research exists on the physical fitness of children with DCD.

Purpose of the Study:

  • Compare health-related physical fitness between Dutch children with DCD and typically developing children (TDC).
  • Investigate the relationship between motor performance issues and physical fitness in children with DCD.

Main Methods:

  • A multicenter case-control study involved 38 children with DCD (ages 7-12) and matched TDC.
  • Motor coordination was assessed using the Movement Assessment Battery for Children.
  • Health-related physical fitness included cardiorespiratory fitness, muscle strength, and BMI.

Main Results:

  • Children with DCD exhibited significantly lower cardiorespiratory fitness (6.7% lower maximal capacity).
  • Muscle strength was significantly reduced in DCD children, particularly elbow and knee flexion.
  • A strong negative association was observed between cardiorespiratory fitness and balance performance.

Conclusions:

  • Children with DCD demonstrate poorer cardiorespiratory fitness and muscle strength than TDC.
  • These findings highlight the need to assess and train cardiorespiratory fitness and muscle strength in children with DCD.
  • Interventions should complement motor coordination training with fitness-focused exercises.
