Primary Outcome Measures:
  • functional capacity [ Time Frame: Change from Baseline in functional capacity at 90 days ] [ Designated as safety issue: No ]
    cardiopulmonary exercise testing (VO2)

Secondary Outcome Measures:
  • respiratory muscle strength [ Time Frame: Change from Baseline in respiratory muscle strength at 90 days ] [ Designated as safety issue: No ]
    PImax e PEmax were obtained using a pressure tansducer

  • Ambulatory blood pressure in 24 hours [ Time Frame: Change from Baseline in blood pressure at 90 days ] [ Designated as safety issue: No ]
    24-hour blood pressure

Estimated Enrollment: 76
Study Start Date: March 2011
Estimated Study Completion Date: December 2012
Estimated Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: stretching exercise Other: Control group -stretching exercise
patients in this group held weekly classes of two stretching for 12 weeks.
Experimental: Tai Chi Chuan exercise Other: Intervention group -Tai Chi Chuan exercise
patients in this group held three weekly classes of 60 minutes during 12 weeks of Tai Chi Chuan, Yang style. The exercises will be mild to moderate (HR 60 to 75% of HR Max). Slow movements combined with exercises and maintained using your own body weight.
