NCT02263482

Brief Summary

Heart failure is a clinical syndrome that is the common end of several cardiac diseases with symptoms such as muscle fatigue, dyspnea and reduction of quality of life. To improve respiratory and general functional capacity of these patients, there are strategies that can be used such as inspiratory muscle training and peripheral muscle training (dynamic resistance training).

Outcome Measures

Primary Outcomes (1)

  • Change in respiratory muscle strength (in centimeters of water)

    Inspiratory and expiratory muscle strength was assessed by using a pressure transducer (MVD-300 Microhard System, GlobalMed, Porto Alegre, Brazil).

    Before and after 8-weeks

Secondary Outcomes (1)

  • walking distance

    Before and after 8-weeks

Other Outcomes (8)

  • Change in pulmonary function

    Before and after 8-weeks

  • Change in functional capacity

    Before and after 8-weeks

  • Inflammation in the upper airway by cytokines in blood

    Before and after 8-weeks

  • +5 more other outcomes

Study Arms (3)

Control group

OTHER

patients awaiting for evaluation to cardiac rehabilitation or transplantation

Other: control

moderate-intensity group

EXPERIMENTAL

Patients will be submitted to a 8-weeks training program, with inspiratory muscle trained at 30% of the maximal inspiratory pressure (30 minutes/session/7 days/week) and peripheral muscle trained with upper and lower exercises (50% of the 1-maximum repetition test).

Other: moderate-intensity group

low-intensity group

ACTIVE COMPARATOR

Patients will be submited to a 8 weeks training program, with inspiratory muscle trained at 15% of the maximal inspiratory pressure (30 minutes/session/7 days/week) and peripheral muscle trained with exercises of upper limbs and lower limbs (0,5 Kg each).

Other: low-intensity group

Interventions

controlOTHER

No intervention during the 8-weeks period of the study because of awaiting evaluation for cardiac rehabilitation or transplantation

Control group

Patients will be submitted to a 8-weeks training program with inspiratory muscle trained at 30% of the maximal inspiratory pressure (30 minutes/session/7 days/week) + peripheral muscle trained with exercises of upper limbs and lower limbs (50% 1 RM, increased every 2-weeks).

moderate-intensity group

Patients will be submited to a 8 weeks training program, with inspiratory muscle trained at 15% of the maximal inspiratory pressure (30 minutes/session/7 days/week) + peripheral muscle trained with exercises of upper limbs and lower limbs (0,5 kg each)

low-intensity group
