According to the Centers for Disease Control and Prevention, CP is the most common physical disability in childhood, significantly influencing muscle control. Physical rehabilitation and strength training interventions play a crucial role in the treatment approach of CP specifically targeting motor deficits. However, not all the training approaches are effective in transferring the improvements related to muscle strength to the activities of daily living (i.e. walking). One strategy that has shown promising results is the functional power training, that includes different exercises involving high velocity movements. To gain insight into this training approach, both architectural and electrophysiological muscle characteristics need to be evaluated during the exercises.
