AB The purpose of this study was to investigate if the performance and metabolic response of cerebral palsy (CP)-athletes to a sustained submaximal exercise on a Petra Race Runner (PRR) was confirm their CP-ISRA classification. Furthermore, the impact of fatigue on the quality of propulsive movement was assessed. Nine athletes with CP from CP-ISRA classes CP1 up to CP6 took part in a 12 minute Cooper Test using a PRR. Changes in heart rate, blood lactate and pace per minute were monitored throughout the test. Results showed that heart rate rose immediately to high levels (a mean of over 160 after the first minute), and was sustained at this level through the test. Blood lactate concentration increased in a curvilinear pattern, but was subject to much inter-individual difference. Analysis from video recordings showed that participants maintained a very consistent movement pattern (step-length, stride frequency) as they became fatigued in the later stages of the Cooper test. The results clearly demonstrated the limitations of using the CP-ISRA classes for PRR competition. No evidence was generated showing an adverse impact of sustained submaximal PRR on the quality of propulsive movement.
