AB  - OBJECTIVE: To examined the effects of different training modalities on exercise 
      capacity (Vo( 2peak)), systolic function, muscular strength and endurance and 
      quality of life in heart failure patients. DESIGN: Randomized controlled trial. 
      SETTING: Cardiac rehabilitation centre in Canada. SUBJECTS: Forty-two individuals 
      with heart failure (62 +/- 12 years; New York Heart Association (NYHA) classes 
      I-III). INTERVENTIONS: Aerobic training (n = 14), combined aerobic and resistance 
      training (n = 15) or usual care (n = 13) three times per week for 12 weeks. MAIN 
      MEASURES: (1) Vo( 2peak) measured by symptom-limited graded exercise test on 
      cycle ergometer; (2) systolic function assessed by two-dimensional 
      echocardiography; (3) muscular strength and muscular endurance measured by 
      one-repetition maximum procedure; and (4) quality of life assessed by 
      questionnaires. RESULTS: In the intention-to-treat analysis, neither aerobic nor 
      combined aerobic and resistance training significantly improved Vo(2peak), 
      systolic function or quality of life compared with usual care. However, combined 
      aerobic and resistance training significantly improved upper extremity strength 
      (40.7 (14.0)-48.5 (16.0) kg, P<0.05) and muscular endurance (5.7 (2.7)-11.6 (7.6) 
      reps, P<0.05) compared with aerobic training or usual care. In compliant 
      participants (exercise adherence 80%), Vo(2peak) increased in the aerobic group 
      (16.9 (6.0)-19.0 (6.8), P= 0.026) and tended to increase in the combined training 
      group (15.9 (5.0)-17.6 (5.6), P= 0.058) compared with usual care. Quality of life 
      was improved in the aerobic group only. CONCLUSIONS: Both aerobic and combined 
      aerobic and resistance training are effective interventions to improve Vo(2peak) 
      in compliant heart failure patients. Combined training may be more effective in 
      improving muscle strength and endurance.
