title: The effects of gender and fatigue on dynamic postural control.
abstract: BACKGROUND
  Deficits in static postural control related to fatigue have been investigated previously, but there is little evidence to link fatigue to performance measures of dynamic postural control.
  
  
  OBJECTIVE
  To investigate the effects of fatigue and gender on performance measures of the Star Excursion Balance Test (SEBT).
  
  
  METHODS
  Mixed-model design.
  
  
  METHODS
  Research laboratory.
  
  
  METHODS
  16 healthy young adults.
  
  
  METHODS
  Subjects performed the SEBT before and after 4 different fatiguing conditions.
  
  
  METHODS
  The normalized reach distances and sagittal-plane kinematics of the knee and hip were recorded.
  
  
  RESULTS
  Fatigue produced deficits in normalized reach distances and decreased knee flexion in all 3 reaching directions. Overall, women were able to reach farther than men while simultaneously demonstrating a greater amount of knee flexion.
  
  
  CONCLUSIONS
  Gender differences were observed during performance of the SEBT, with women demonstrating greater reach distances and knee flexion, and fatigue amplified these differences.
