Acute Response to One Bout of Dynamic Standing Exercise on Blood Glucose and Blood Lactate Among Children and Adolescents With Cerebral Palsy Who are Nonambulant

• Purpose: To investigate the acute exercise effects of dynamic standing exercise (DyS) on blood glucose and blood lactate among children and adolescent with cerebral palsy (CP) who are non-ambulant. Methods: Twenty-four participants with CP who are non-ambulant performed 30 minutes of DyS using a motorized device enabling assisted passive movements in an upright weight-bearing position. Capillary blood-samples were taken from the fingertip for measurement of blood glucose and blood lactate at rest and at the end of exercise. Results: At rest, the participants had hyperlactatemia that was unaffected after exercise presented as median and interquartile range at rest 1.8 [1.3:2.7] mmol/L and after exercise 2.0 [1.1:2.5] mmol/L. Children and adolescents with GMFCS-E&R V had higher lactate levels at rest (2.5 [1.8:2.9] vs 1.4 [1.0:2.0]; p=0.030) and after exercise (2.3 [2.0:2.6] vs 1.2 [0.9:2.2]; p=0.032) compared to children and adolescents with GMFCS-E&R IV respectively. A statistically significant larger decrease in blood lactate levels after exercise was observed in children and adolescents with higher resting blood lactate levels (rho=0.56;p=0.004). There were no statistically significant changes in blood glucose. Conclusions: Forty percent of the participants had mild hyperlactatemia at rest and participants with the highest blood lactate levels at rest had the greatest decrease in blood lactate levels after one bout of exercise. Children and adolescents with classified into higher level of GMFCS-E&R had higher blood lactate levels. More studies are needed on how to prevent chronically high resting levels of lactate with exercise in children with CP who are non-ambulant.
