title: [Clinical effects of sub-maximum ergometry exercise rehabilitation in patients with chronic obstructive pulmonary disease].
abstract: OBJECTIVE
  To study the rehabilitation effects ergometry on COPD patients.
  
  
  METHODS
  Thirty COPD out-patients in our Hospital were randomly divided into 2 groups. Rehabilitation group, 15 patients, performed leg ergometry exercise of 80% peak Watt x 30min/d x 3d/w x 12w. Another 15 patients were control group without exercise. All patients received conventional therapy. Pulmonary function testing (PFT), cardiopulmonary exercise testing (CPET), arterial blood gas analysis (ABG), Borg and CAT sores were done at both baseline and 12 w.
  
  
  RESULTS
  There was no statistically difference in lung function testing, blood gas analysis and cardiopulmonary exercise test when pre- exercises between 2 sub-groups. The IC, peak VO2 and peak, W of rehabilitation group significantly increased (P < 0.05); and Borg and CAT.scores significantly decreased (P < 0.05) from baseline; and other PFT and ABG did not change (P > 0.05). While there was no difference in control group (P > 0.05).
  
  
  CONCLUSIONS
  Leg submaximal ergometry rehabilitation improves health condition and ameliorate dyspnea symptoms in COPD patients.
