title: The effect of increasing effort on movement economy during incremental cycling exercise in individuals early after acquired brain injury.
abstract: OBJECTIVE
  To investigate the effect of increasing effort on energy cost as measured by oxygen consumption (VO2) during cycling exercise in individuals early after acquired brain injury (ABI).
  
  
  METHODS
  An experimental correlation design.
  
  
  METHODS
  Specialist neurorehabilitation centre.
  
  
  METHODS
  Thirty-eight individuals were recruited early after acquired brain injury. Nine individuals had spasticity; Ashworth Scale >1 in either upper or lower limbs.
  
  
  METHODS
  The VO2 was measured in relation to workload during a graded exercise test.
  
  
  RESULTS
  The VO2 increased in a linear fashion with increases in workload in 34 individuals. Only one individual with spasticity demonstrated a nonlinear relationship.
  
  
  CONCLUSIONS
  Increasing the workload during cycling exercise does not disproportionately increase energy cost in most individuals with spasticity early after ABI.
