Aerobic capacity in children and adolescents with cerebral palsy.
Expect kids with CP to tire faster than peers—girls decline steeper with age, so adjust exercise load early.
01Research in Context
What this study did
Verschuren et al. (2010) tested how much oxygen kids with cerebral palsy can use while running. They compared kids with mild CP to kids who walk normally.
The study took place in a lab. Each child walked on a treadmill while wearing a mask that measured their breath.
What they found
Kids with CP had much lower aerobic capacity than their peers. The gap was bigger for girls and grew as they got older.
Even children who could walk without help showed clear fitness deficits.
How this fits with other research
Keawutan et al. (2014) looked at ten studies and found the same pattern. Kids with better motor skills move more during daily life. Olaf’s lab data help explain why: poor aerobic capacity makes activity harder.
Neyroud et al. (2017) showed that young adults with CP also have weaker calf muscles that tire slowly. Together, these studies paint a picture: CP affects both muscle power and heart-lung fitness.
Larsson et al. (2018) tested treadmill walking in girls with Rett syndrome. They also saw low energy output. The message is similar across neurodevelopmental disorders: plan for lower fitness levels.
Why it matters
When you write exercise goals, set the bar lower than charts for typical kids. Start with short bouts and monitor heart rate. Build endurance slowly, especially for girls approaching adolescence. Pair aerobic work with strength training to tackle both weak muscles and low stamina.

03Original abstract
This study described the aerobic capacity [VO(2peak) (ml/kg/min)] in contemporary children and adolescents with cerebral palsy (CP) using a maximal exercise test protocol. Twenty-four children and adolescents with CP classified at Gross Motor Functional Classification Scale (GMFCS) level I or level II and 336 typically developing children were included. All children performed a progressive exercise test on a treadmill with respiratory gas-exchange analysis. The results are compared with normative values for age and gender-matched controls. Aerobic capacity of children and adolescents with CP, who are classified at GMFCS level I or II was significantly lower than that of typically developing controls. Especially in girls with CP, the aerobic capacity deteriorated with age. The aerobic capacity of contemporary children and adolescents with CP, who are classified at GMFCS level I or II is significantly lower than that of typically developing controls.
