Study Arms:
- Patients with cerebral palsy (Type: EXPERIMENTAL): A specially adapted recumbent cycle ergometer with the ability to quickly transform into an isometric dynamometer will be used to assess fatigability development during a task to failure. Throughout the task, which consists of blocks of 3 minutes, neuromuscular assessments will take place to determine the evolution of fatigability and its peripheral and central determinants.
- Healthy people (Type: ACTIVE_COMPARATOR): A specially adapted recumbent cycle ergometer with the ability to quickly transform into an isometric dynamometer will be used to assess fatigability development during a task to failure. Throughout the task, which consists of blocks of 3 minutes, neuromuscular assessments will take place to determine the evolution of fatigability and its peripheral and central determinants.

Based on this trial design, predict the completion outcome and termination type (if applicable).
