Aerobic, Resistance, Inspiratory Training Outcomes in Heart Failure
Condition: Heart Failure
MeSH terms: Heart Failure
Study type: Interventional

Summary: 
      This study investigates the effects of aerobic, resistance, inspiratory training modalities
      outcomes in functional capacity and quality of life of heart failure (HF) patients, aiming
      for the 'optimum' (greek, αριστος=aristos) training program for HF patients.
    

Detailed description: 
      Heart failure is a clinical syndrome characterized by symptoms of dyspnea, exercise
      intolerance and decreased quality of life. A weakness in both inspiratory and peripheral
      muscles is also reported. Aerobic training (AT) improves the functional status of HF patients
      (level of evidence IA). Additional benefits of inspiratory muscle training (IMT) and/or
      resistance training (RT) when combined with aerobic training (AT) in HF symptoms have also
      been found.

      Four exercise groups will be studied in order to identify the optimum exercise program I.
      Aerobic-Resistance-Inspiratory training (ARIS) group II. Aerobic Training-Resistance Training
      (AT/RT) group III. Aerobic training-Inspiratory Muscle Training (AT/IMT) group IV. Aerobic
      Training (AT) group

Intervention description(s): Patients will be submitted to a 12 week, 3 times/week, continuous aerobic (e.g. bike) training programme at an intensity of 60-80% max HR (or peakVO2) for 30 min combined with resistance training at an intensity of 50% of 1 Repetition Maximum (1RM) for quads training and upper limb exercises (elbow flex/shoulder flex/abd) using dumbbells (1-2 kg) (12-15 reps/3sets) for 10 min, combined also with inspiratory muscle training with a flow-resistive loading system at an intensity of 60% of maximal inspiratory pressure/sustained maximal inspiratory pressure (PImax/SPImax) for 20 min (Aerobic (30min) + Resistance (10min) + Inspiratory (20min) = 60 min); Patients will be submitted to a 12 week, 3 times/week, continuous aerobic (e.g. bike) training programme at an intensity of 60-80% max HR (or peakVO2) for 30 min combined with resistance training at an intensity of 50% of 1RM for quads training, pectoralis m, serratus anterior m, and latissimus dorsi m and upper limb exercises (elbow flex/shoulder flex/abd) using dumbbells (1-2 kg) (12-15 reps/3sets).
(Aerobic (30min) + Resistance (30min) = 60 min); Patients will be submitted to a 12 week, 3 times/week, continuous aerobic (e.g. bike) training programme at an intensity of 60-80% max HR (or peakVO2) for 30 min combined with inspiratory muscle training with a flow-resistive loading system at an intensity of 60% of maximal inspiratory pressure/sustained maximal inspiratory pressure (PImax/SPImax) for 30min (Aerobic (30min) + Inspiratory (30min) = 60 min); Patients will be submitted to a 12 week, 3 times/week continuous aerobic (e.g. bike) training programme at an intensity of 60-80% max HR (or peakVO2) for 30 min combined with callisthenics progressing to treadmill or bike (at the same intensity) for 30 min (Aerobic training = 60 min)
